Can Subcontractors File Liens? (w/Examples) + FAQs

Yes. Subcontractors can file mechanics liens on private construction projects and bond claims on public projects. These legal tools protect subcontractors from non-payment when property owners or general contractors fail to pay for labor and materials provided.

Mechanics lien statutes exist in all 50 states to address a critical problem: subcontractors lack direct contracts with property owners. Under common law, only parties with direct contractual relationships can sue each other for breach of contract. This creates a dangerous payment gap where a subcontractor completes work, the property owner pays the general contractor, but the general contractor fails to pay the subcontractor.

Without statutory lien rights under state law or bond claim rights under the Miller Act (40 U.S.C. §§ 3131-3134), subcontractors would face the immediate negative consequence of providing thousands or millions of dollars in labor and materials with no guaranteed payment mechanism and no legal claim against the property that their work improved.

The construction industry faces a $299 billion annual crisis from slow payments in 2025. According to research by Rabbet, delayed payments create a hidden 14% tax on all construction projects, with 70% of contractors regularly experiencing payment delays that threaten their business survival and force them to inflate bids by an average of 8% to protect against non-payment.

Understanding Subcontractor Lien Rights

Subcontractors occupy a unique position in construction payment hierarchies. A subcontractor is any person or company that contracts with the general contractor or another subcontractor to perform work or supply materials for a construction project. These parties do not have direct contractual relationships with property owners, which creates the fundamental problem that mechanics lien laws solve.

The legal framework distinguishes between different tiers of subcontractors. A first-tier subcontractor contracts directly with the prime contractor (general contractor). A second-tier subcontractor contracts with a first-tier subcontractor. Some states extend lien rights to third-tier subcontractors, but many do not.

This tier system matters because it determines which parties you must notify and which deadlines apply. In some jurisdictions like the District of Columbia, only parties contracting directly with the owner or prime contractor have lien rights. If you furnish materials to a subcontractor or sub-subcontractor in DC, you cannot file a mechanics lien regardless of how much you are owed.

State mechanics lien statutes create a security interest in real property. This means the subcontractor gains a legal claim against the physical property where work was performed. If payment is not received, the subcontractor can foreclose on the lien and force the sale of the property to satisfy the debt. This powerful remedy explains why property owners take lien claims seriously and why filing a lien often prompts immediate payment negotiations.

Federal Law: The Miller Act for Public Projects

You cannot file a mechanics lien against property owned by federal, state, or local governments. Public policy prohibits placing liens on taxpayer-funded property because foreclosure and forced sale of government buildings would disrupt essential public services. The Miller Act addresses this gap for federal construction projects exceeding $100,000.

Under the Miller Act, prime contractors must furnish payment bonds that guarantee subcontractors and suppliers will be paid. The surety company that issues the bond becomes liable if the general contractor fails to pay. This substitutes the bond for the property as the source of payment protection.

The Miller Act protects four categories of claimants: (1) those who furnish labor or materials to the prime contractor, (2) those who furnish labor or materials to a first-tier subcontractor, (3) first-tier material suppliers, and (4) second-tier material suppliers contracting with first-tier subcontractors. Remote subcontractors beyond these tiers cannot recover against Miller Act bonds.

Notice requirements differ dramatically based on your tier. If you contract directly with the prime contractor (first-tier), no notice is required before filing suit. However, if you contract with a first-tier subcontractor (second-tier), you must provide written notice of non-payment to the prime contractor within 90 days after your last day of furnishing labor or materials. This notice must include the amount claimed and the party for whom the work was performed.

The deadline to file suit under the Miller Act is strict: no later than one year after the last day you furnished labor or materials. You must wait 90 days after your final furnishing before filing suit, but you cannot wait beyond one year. Missing this one-year deadline completely extinguishes your payment rights with no exceptions.

“Pay when paid” and “pay if paid” clauses in subcontracts do not defeat Miller Act bond rights. Federal courts uniformly hold that allowing sureties to avoid liability based on these clauses would defeat the Miller Act’s purpose of protecting subcontractors. A subcontractor can recover against a Miller Act surety even if the government has not yet paid the prime contractor.

State Mechanics Lien Laws for Private Projects

Private construction projects are governed by state mechanics lien statutes that vary significantly in their requirements and deadlines. Every state has mechanics lien laws, but the specific procedures differ enough that a lien filed properly in California would be invalid in Texas using the same procedures.

Three fundamental requirements exist in most states. First, the claimant must be within a certain number of tiers from the property owner. Most states allow first-tier and second-tier subcontractors to file liens, though some restrict rights to parties contracting directly with the general contractor or owner.

Second, the materials or labor must become part of the permanent improvement to the property. Suppliers of consumable items that do not become part of the building (such as fuel for construction equipment) typically cannot file liens. The work must be “affixed” to or become a “permanent part” of the improvement.

Third, suppliers to suppliers generally do not have lien rights. If you sell lumber to a lumber yard, and that lumber yard sells the lumber to a contractor, you cannot file a lien against the property where the lumber was used. Your customer must be installing the materials, or your customer’s customer must be doing so.

Preliminary Notice Requirements

The majority of states require subcontractors to send preliminary notices before they can later file mechanics liens. A preliminary notice (also called a “notice to owner,” “notice of furnishing,” or “20-day notice”) informs the property owner and other parties that you are providing labor or materials to the project. This protects owners from surprise liens and establishes your identity in the payment chain.

California requires subcontractors to serve a preliminary notice within 20 days of first furnishing labor or materials. If you send the notice late, you can only claim a lien for work performed within the 20 days immediately before the notice was sent. All earlier work is unprotected. The notice must be sent to the property owner, the prime contractor, and the construction lender if any exists.

Arizona requires a 20-day preliminary notice from all contractors, including general contractors working on projects with lenders. Failure to send this notice within 20 days results in complete loss of lien rights for all work performed before the notice. Unlike California, Arizona provides no grace period to catch up.

Texas does not require preliminary notices from general contractors for most projects. However, subcontractors must send a notice within the earlier of the 15th day of the second month after each month work is performed or the 15th day of the fourth month after the original contract was executed. This complex timing requirement makes Texas one of the most technically demanding lien law states.

Florida requires subcontractors to serve a Notice to Owner within 45 days after first furnishing labor or materials. The notice must include specific statutory warning language in capital letters and must be sent by certified mail or other specified delivery methods. Property owners in Florida must record a Notice of Commencement before construction begins, which identifies all parties involved and shortens lien filing deadlines.

States that do not require preliminary notices include Connecticut, Maryland, Massachusetts, New Jersey, New York, Pennsylvania, Vermont, and Wyoming. In these jurisdictions, subcontractors proceed directly to filing liens without advance notice, though deadlines still apply.

Lien Filing Deadlines by State

The deadline to file a mechanics lien begins running from specific trigger dates that vary by state. Common trigger points include: (1) the date the subcontractor completes its work, (2) the date the entire project is completed, (3) the date the owner records a Notice of Completion, or (4) the date a Notice of Cessation is filed.

StateFiling DeadlineNotice of Completion ImpactEnforcement Deadline
California90 days after project completionShortened to 30 days for subs, 60 for GCs90 days after lien recorded
Arizona120 days after project completionShortened to 60 days6 months after lien recorded
Texas15th of 3rd month after completion for retained funds; 15th of 4th month for original contract amountsN/A2 years after last work or 1 year after completion
Florida90 days after final workShortened to 45 days1 year after lien recorded
New York8 months after last work30 days after filing1 year after filing

Notice of Completion filings dramatically shorten deadlines. Property owners can file these documents with county recorders after project completion specifically to accelerate lien deadlines. Many subcontractors lose their lien rights entirely because they did not know a Notice of Completion was filed and missed the shortened 30-day or 45-day deadline.

The Three Most Common Subcontractor Lien Scenarios

ScenarioResult
Scenario 1: Unpaid Electrical Subcontractor on Private Commercial Building
Metro Electric contracts with ABC General Contractors to install electrical systems in a new office building for $250,000. Metro Electric completes all work in March 2026. ABC General Contractors receives full payment from the building owner but declares bankruptcy in April 2026 without paying Metro Electric. Metro Electric sent a 20-day preliminary notice within the deadline.
Metro Electric can file a mechanics lien against the office building property by June 2026 (90 days after March completion in California). The lien attaches to the property even though the owner paid ABC General Contractors in full. The owner faces potential double payment (once to ABC, again to Metro Electric) because the owner failed to protect itself by requiring lien waivers before paying ABC. Metro Electric can foreclose the lien and force sale of the property if not paid.
Scenario 2: Sub-Subcontractor Plumbing Supplier
City Plumbing Supply sells $50,000 in copper pipes and fixtures to West Coast Plumbing, a first-tier subcontractor. West Coast Plumbing installs these materials in a luxury home project. West Coast Plumbing contracts with the general contractor, but City Plumbing Supply has no direct relationship with the general contractor or property owner. West Coast Plumbing fails to pay City Plumbing Supply. City Plumbing Supply did not send a preliminary notice.
City Plumbing Supply cannot file a mechanics lien in most states because it failed to send the required preliminary notice. In states like California that allow late notices, City Plumbing Supply can file a notice immediately and then file a lien, but it can only claim payment for materials delivered in the 20 days before the notice. The $50,000 worth of earlier materials cannot be secured by lien. City Plumbing Supply’s only remedy is suing West Coast Plumbing for breach of contract.
Scenario 3: HVAC Contractor on Federal Government Building
Summit HVAC, a first-tier subcontractor, contracts with Prime Federal Contractors to install heating and cooling systems in a new federal courthouse for $1.2 million. Prime Federal Contractors received a payment bond as required by the Miller Act. Summit HVAC completes all work in August 2025 but receives only $900,000 in payment. Prime Federal Contractors refuses to pay the remaining $300,000, claiming defects. Summit HVAC disputes these defect allegations.
Summit HVAC cannot file a mechanics lien because government property is immune. However, Summit HVAC has Miller Act bond claim rights. Because Summit HVAC is a first-tier subcontractor (direct contract with prime contractor), no preliminary notice to Prime Federal Contractors is required. Summit HVAC must wait until November 2025 (90 days after final work in August) before filing suit against the payment bond. The deadline to file suit is no later than August 2026 (one year after last furnishing labor). Summit HVAC sues the surety company that issued the bond, not the federal government.

Required Information for Mechanics Lien Documents

Mechanics lien statutes require specific information in lien filings. Omitting required elements or stating information incorrectly renders the lien invalid. Courts interpret these requirements strictly because lien laws are “in derogation of common law” and represent extraordinary remedies that can force property sales.

Every mechanics lien must include: (1) the claimant’s name and address, (2) the name and address of the person who hired the claimant, (3) the name and address of the property owner or reputed owner, (4) the name and address of the general contractor, (5) the amount claimed after deducting all credits and offsets, (6) a description of the labor performed or materials supplied, and (7) a legally sufficient description of the property.

Property Description Requirements

Property descriptions cause more lien rejections than any other element. Simply listing the street address (“123 Main Street”) is insufficient in most states. You must provide a legal description that identifies the property with certainty according to official county records.

Three types of legal descriptions are acceptable: (1) metes and bounds descriptions that define the property boundaries by direction and distance (“Beginning at the northeast corner, thence south 100 feet, thence west 50 feet…”), (2) lot and block descriptions from recorded subdivision plats (“Lot 7, Block 3, Riverside Addition”), or (3) government survey descriptions using townships, ranges, and sections.

The best practice is obtaining the legal description from the most recent deed transferring the property. This information is available from title companies or county recorder offices. Some states allow you to reference the deed by recording information (“as described in Deed recorded at Book 450, Page 89”).

The standard for adequacy is whether the description contains “a nucleus of information that could enable a party familiar with the locality to identify the premises intended to be described with reasonable certainty.” However, relying on this lenient standard is dangerous. When property descriptions are challenged, courts examine whether a surveyor could locate the precise boundaries. Ambiguous descriptions result in lien invalidation.

Service and Notice Requirements After Filing

Filing the lien with the county recorder is not the final step. Most states require the lien claimant to serve a copy of the recorded lien on specific parties within a short deadline. Failure to serve the lien properly invalidates it even if the filing itself was timely and correct.

California requires service of a copy of the claim of mechanics lien on the property owner or reputed owner. Service may be accomplished by registered mail, certified mail, or first-class mail with certificate of mailing. The lien document itself must include statutory warning language in 10-point boldface type that explains the lien’s effect.

Florida requires service of the lien on the property owner and general contractor by certified mail within 15 days after recording the lien. Texas requires service within 5 days after filing. Missing these short service deadlines voids the lien entirely.

The proof of service must be attached to the original lien or filed separately with the county recorder. This creates a permanent record that service was completed. If you later file a lawsuit to foreclose the lien, you must prove proper service occurred. Failure to document service properly can result in dismissal of foreclosure actions even years later.

Mistakes to Avoid When Filing Mechanics Liens

The technical nature of lien statutes creates numerous pitfalls that cost subcontractors their payment rights. These errors occur even when the underlying claim is legitimate and the property owner or general contractor genuinely owes the money.

Mistake 1: Naming the Wrong Property Owner. You must identify the legal owner of the property, not merely the occupant or the person you dealt with. Properties owned by limited liability companies require the exact LLC name as shown on the title. Properties owned in trusts require identifying the trustee. A lien naming “John Smith” when the property is actually owned by “Smith Family Trust, Jane Smith Trustee” is invalid. Use title companies to verify ownership before filing.

Mistake 2: Missing the Last Date of Work. The filing deadline depends on accurately stating when you last provided labor or materials. Property owners routinely challenge liens by examining emails, text messages, and invoices to prove the last date was earlier than stated. If the claimant misstates this date and the deadline has actually passed, the lien is invalidated entirely. Document your final day on site with photographs, delivery receipts, and contemporaneous records.

Mistake 3: Failing to Send Required Preliminary Notices. This is the single most common reason subcontractors lose lien rights. In states requiring preliminary notices, filing a lien without having sent the notice first makes the lien completely unenforceable. Some contractors mistakenly believe they can send the preliminary notice at the same time as filing the lien, but statutes require the notice at the beginning of the project, not at the end. Late notices in California provide limited protection for only 20 days of prior work. States like Arizona provide no protection for work before the notice at all.

Mistake 4: Using Improper Service Methods. Sending the preliminary notice or lien by regular mail, email, or hand delivery may not satisfy statutory requirements. Most states mandate certified mail, registered mail, or certified mail with return receipt requested. Some states allow personal service by a licensed process server. Using the wrong service method means the notice was never legally delivered, voiding all lien rights that depend on that notice. Always use certified mail with return receipt and retain the receipts in your permanent file.

Mistake 5: Including Incorrect Dollar Amounts. The lien amount must represent only the unpaid balance for labor and materials provided, after deducting payments received and credits acknowledged. Including inflated amounts, penalties, damages for delay, or other items not directly related to the physical work can invalidate the entire lien. Courts view exaggerated lien amounts as fraudulent and may dismiss the claim with prejudice. Some jurisdictions impose penalties or attorney’s fees against claimants who overstate lien amounts by significant margins.

Mistake 6: Serving the Lien on the Wrong Parties. You must serve copies of the filed lien on all required parties. At minimum this includes the property owner and the general contractor. If you are a lower-tier subcontractor, you must also serve all contractors above you in the payment chain. Missing even one required party invalidates the lien. Obtain a list of all contractors from the preliminary notice or Notice of Commencement and serve everyone listed.

Mistake 7: Letting the Lien Expire Without Enforcement. A recorded mechanics lien does not last forever. Every state imposes deadlines to “perfect” or “enforce” the lien by filing a foreclosure lawsuit. These enforcement deadlines range from 90 days in California to 2 years in Texas. If you do not file a lawsuit to foreclose the lien before the deadline expires, the lien becomes unenforceable and disappears. The property owner can then demand you execute a lien release, and if you refuse, can sue you for wrongfully clouding title to the property.

A 2016 case in Illinois, Rockford Structures Construction Company, demonstrates how technical compliance requirements can destroy otherwise valid lien claims. A union filed a mechanics lien for $23,595.28 in unpaid wages and benefits. The union properly filed the lien within 90 days and sent notice to all parties. However, the property owner had already paid the general contractor in full based on sworn statements showing all subcontractors were paid. The court held that subcontractors’ lien claims are limited to amounts still due from owner to general contractor at the time the owner receives notice of the lien. Because nothing was owed to the general contractor when the owner got notice, the union’s lien was invalid despite the union doing everything correctly.

This case illustrates the harsh reality for second-tier and lower subcontractors: you are completely dependent on the general contractor not being paid before the owner learns of your claim. To protect against this, send preliminary notices immediately when starting work, monitor for Notices of Completion that shorten deadlines, and file liens promptly when payment problems arise rather than waiting months while hoping for voluntary payment.

Do’s and Don’ts for Subcontractor Lien Rights

Do’s

Do send preliminary notices at the very beginning of every project, even if not required by law. This creates a paper trail establishing your involvement, notifies property owners of your participation, and preserves your options. In states not requiring preliminary notices, voluntary notices still provide tactical advantages by warning owners and general contractors that you understand your rights. The minimal cost of certified mail is insignificant compared to the protection provided.

Do monitor for Notices of Completion at county recorder offices. Property owners file these documents specifically to shorten your lien deadlines from 90 days to 30 days (or similar reductions). Many lien services and title companies offer automated monitoring that alerts you within 24 hours of a Notice of Completion being filed. The notification fee is a small price to pay for avoiding complete loss of your lien rights by missing a shortened deadline you did not know existed.

Do obtain lien waivers from your own subcontractors and suppliers before paying them. If you pay a sub-subcontractor who then files a lien, and that lien is valid, the property owner can withhold funds from you to cover the lien. You will have paid your subcontractor and still not be credited for that payment by the owner. Conditional lien waivers given before payment and unconditional lien waivers exchanged for payment protect you from paying twice for the same work.

Do keep detailed daily logs, photographs, and delivery receipts. If your lien is challenged, you must prove what work you did and when you did it. Memories fade and generic invoices lack credibility. Contemporary documentation created while the work was happening is powerful evidence. Photograph the site at the beginning and end of each week showing work progress. Save all text messages and emails discussing the project. These materials become critical evidence in foreclosure lawsuits.

Do consult with construction lawyers before executing lien waivers requested by general contractors. Many waiver forms contain broad language releasing not only lien rights but also all claims for extras, delays, and acceleration. Once signed, these waivers are enforceable even if the waiver amount is less than what you are truly owed. Never sign a waiver that releases more than the specific payment amount you are receiving in exchange.

Do understand the difference between “pay when paid” and “pay if paid” clauses. “Pay when paid” clauses (stating you will be paid within X days after the general contractor is paid by the owner) create timing provisions but do not eliminate your payment rights. “Pay if paid” clauses (stating you will be paid only if and when the general contractor is paid) attempt to shift the owner’s credit risk to you. Many states void “pay if paid” clauses as against public policy. On federal projects, Miller Act bond rights cannot be defeated by either type of clause.

Don’ts

Don’t rely on verbal promises that payment is coming soon. One of the most common mistakes is failing to file a lien because the general contractor repeatedly promises payment is “in the mail” or “being processed.” While these delays continue, lien filing deadlines are expiring. Many contractors lose their lien rights entirely by waiting too long based on assurances that proved false. If payment deadlines pass without receiving money, file the lien immediately. You can always release it later if payment comes through.

Don’t file a lien for amounts you are not actually owed. Inflating lien amounts or including damages, penalties, or unrelated charges can result in the entire lien being declared fraudulent. Courts take seriously the extraordinary remedy of placing a lien on someone’s property. Subcontractors who overstate claims by substantial amounts face dismissal of their claims, requirements to pay the owner’s attorney’s fees, and potential criminal liability for filing false liens. If there is a good-faith dispute about whether certain work was authorized or materials were delivered, include detailed explanations in the lien affidavit rather than simply inflating the number.

Don’t miss service deadlines after filing the lien. Filing the lien with the county recorder is only half the process. You must also serve copies on required parties within short deadlines (often 5 to 15 days). Missing these service requirements invalidates the lien. Set calendar reminders for service deadlines immediately upon filing the lien, and use certified mail with return receipt so you have proof of service.

Don’t waive lien rights in advance of performing work. Many general contractor subcontract forms include “no lien” clauses requiring the subcontractor to agree it will not file liens. These provisions are void and unenforceable in most states as against public policy. Arkansas law makes it a criminal offense for contractors to request lien waivers from subcontractors in advance of payment. North Carolina recently amended its lien law to void any lien waiver unless “limited to the specific interim or progress payment actually received by the promisor in exchange for the lien waiver.” Never sign a contract containing broad advance waivers of lien rights.

Don’t provide materials or labor to suppliers to suppliers. If you sell materials to a supplier who then sells to a contractor, you generally have no lien rights even if your materials end up in a building project. Your direct customer must be someone who is installing the materials, or your customer’s customer must be. The general rule is that “suppliers to suppliers do not have lien rights.” Before supplying materials to a new customer, determine their relationship to the actual construction project.

Don’t assume your lien will remain enforceable indefinitely. Liens do not last forever. Enforcement deadlines requiring foreclosure lawsuits range from 90 days to 2 years depending on the state. If you file a lien and then do nothing, it will expire and become unenforceable. Property owners can then force you to release it, and if you refuse, can sue you for wrongfully maintaining an expired lien. Set enforcement deadline reminders immediately upon filing any lien.

Pros and Cons of Filing Mechanics Liens

Pros

Liens provide powerful leverage in payment negotiations. The mere filing of a lien often produces immediate payment because property owners cannot sell or refinance property with outstanding liens clouding the title. Lenders will not fund loans on properties with lien claims. Real estate transactions cannot close until all liens are paid or bonded. This creates urgent pressure on owners to resolve lien claims quickly even when the owner believes the claim is not fully justified.

Liens attach to the property regardless of who owns it. Once properly recorded, a mechanics lien remains attached to the property even if it is sold to a new owner. The new owner takes the property subject to the lien and becomes responsible for satisfying it. This protects subcontractors against property owners who attempt to avoid payment by transferring property to shell companies or family members.

Lien foreclosure can result in forced sale of the property. If payment is not received after filing a lien, you can file a lawsuit to foreclose the lien. If you win, the court can order the property sold at auction with proceeds applied to pay your claim. While foreclosure is rare because cases usually settle before trial, the threat of foreclosure creates substantial motivation for owners to pay rather than risk losing their property.

Mechanics liens have priority over many other interests in property. In most states, properly perfected mechanics liens take priority over mortgages and other encumbrances recorded after construction began, and in some states they even take priority over earlier mortgages. This means you may be paid from sale proceeds before the mortgage lender is paid. The “relation back” doctrine causes liens to relate back to the date construction commenced rather than the date the lien was filed, giving them earlier effective priority dates.

Filing liens is relatively inexpensive compared to litigation. Recording fees for filing liens with county recorders typically range from $25 to $100. Certified mail for notices costs a few dollars. The total out-of-pocket cost to preserve tens of thousands or millions of dollars in payment rights is minimal. In contrast, filing a breach of contract lawsuit without a lien can cost $5,000 to $10,000 in attorney’s fees just to initiate the case.

Cons

Strict compliance with technical requirements is mandatory. As discussed throughout this guide, mechanics lien statutes impose numerous specific requirements for notices, filing deadlines, service procedures, and lien content. Missing any single requirement by even one day or one technical detail completely invalidates the lien. This unforgiving nature of lien laws means many otherwise legitimate claims fail because of procedural errors rather than lack of merit.

Filing liens can damage business relationships. Placing a lien on a general contractor’s project signals distrust and creates adversarial positioning. Some contractors refuse to hire subcontractors who have filed liens on past projects, viewing them as litigious or difficult to work with. While this reaction is unfair (filing liens is a legal right), the practical reality is that liens can harm your reputation and cost future work opportunities from contractors who pay reliably but dislike the aggressive approach.

Liens do not guarantee payment. Filing a mechanics lien creates a security interest and legal claim, but it does not automatically result in money in your bank account. You must still file a foreclosure lawsuit, prove your case in court, obtain a judgment, and execute on the judgment. If the property value is less than the amounts owed to senior lienholders (mortgage lenders), there may be no equity available to pay your claim even if you win.

Enforcement deadlines create additional pressure and costs. After filing a lien, you face a new deadline to file a foreclosure lawsuit. This enforcement deadline forces you to make a decision: invest substantial money in litigation to perfect the lien, or allow the lien to expire. Filing foreclosure lawsuits typically costs $10,000 to $50,000 in attorney’s fees depending on complexity. Many subcontractors file liens hoping to prompt settlement but cannot afford to follow through with litigation if settlement fails.

Subcontractor liens can be limited to amounts owed to general contractors. The harsh rule in many states is that subcontractors can only recover amounts the property owner still owes to the general contractor when the owner receives notice of the subcontractor’s claim. If the owner has already paid the general contractor in full, the subcontractor’s lien may be worthless even though the subcontractor properly followed all procedures. This rule transfers to subcontractors the risk that general contractors will be paid but not disburse payments downstream.

Public Projects and Payment Bond Claims

Mechanics liens do not apply to publicly owned property. Governmental entities cannot be subjected to liens because foreclosure and forced sale of government buildings would disrupt public services and waste taxpayer resources. Police stations, courthouses, schools, and other public buildings are immune from lien claims.

State and local “Little Miller Acts” provide equivalent protections through payment bonds. These statutes require general contractors on public projects to post bonds guaranteeing payment to subcontractors and suppliers. The bond functions as substitute collateral replacing the property itself as the source of payment security.

Most states require payment bonds on public projects exceeding threshold amounts, typically $25,000 to $100,000. The bond amount usually equals 100% of the contract price. Subcontractors file claims against the bond rather than against the property. The surety company that issued the bond becomes liable for unpaid subcontractors up to the bond amount.

Notice requirements for bond claims mirror lien notice requirements in many states, but deadlines differ. Florida requires subcontractors on public projects to serve a Notice to Contractor within 45 days of first furnishing labor or materials, similar to the Notice to Owner required on private projects. However, the consequence of missing the deadline on a public project is complete loss of bond rights rather than inability to file a lien.

Georgia’s Little Miller Act allows second-tier and third-tier subcontractors to file claims, extending protection beyond the Miller Act’s limitation to first-tier and second-tier parties. This broader coverage reflects state policy choices to provide greater payment security for all project participants.

The deadline to file suit on payment bonds varies by state but typically ranges from six months to two years after last furnishing labor or materials. These deadlines are strictly enforced. The surety company’s obligation under the bond is conditioned on the claimant filing suit within the statutory period.

When working on projects involving both public and private property, such as a mixed-use development where a private developer is leasing government land, the characterization as public or private determines your remedies. Courts examine who owns the underlying real property. Improvements constructed on leased government land are generally treated as public projects even though a private developer is involved, because the land itself cannot be subjected to a lien.

Retainage and Subcontractor Lien Rights

Retainage refers to portions of contract payments that the hiring party withholds until completion of the work or satisfaction of specific conditions. General contractors commonly retain 10% of amounts owed to subcontractors until the entire project is complete and all issues are resolved. This practice protects the party withholding retainage against defects, incomplete work, or lien claims from lower-tier parties.

State laws regulate retainage amounts and release timing. Texas requires owners to retain 10% of payments due to general contractors to protect against subcontractor lien claims. This “reserved fund” must remain unpaid until deadlines for subcontractors to file liens expire. If the owner pays the general contractor in full without retaining the required 10%, the owner becomes personally liable to subcontractors up to the amount that should have been retained.

Contractual retainage agreed to in the subcontract (as opposed to statutory retainage required by law) extends the time for filing liens in many states. Rather than the lien right accruing when the subcontractor completes its own work, the right accrues when the retainage becomes payable under the subcontract. This later accrual date pushes back the filing deadline.

For example, if a subcontractor completes work in March but the subcontract states retainage will be paid 30 days after the entire project is complete, and the entire project finishes in June, the subcontractor’s lien filing deadline begins running in July (30 days after June) rather than in March. This extended deadline helps subcontractors whose contracts tie payment to overall project completion.

To preserve lien rights for retainage in Texas, subcontractors must file an affidavit claiming a lien for retainage by the 15th day of the third month after the month when the original contract (between owner and general contractor) is completed, terminated, or abandoned. This is a different deadline than the deadline for claiming labor and materials provided during the project.

Property owners who receive affidavits claiming retainage must withhold contract payments from the general contractor sufficient to cover the retainage claims. This withholding may equal or exceed the value of other funds owed, provided unpaid contract funds remain available. The owner essentially freezes payments to the general contractor until the retainage dispute is resolved.

Lien Waivers and Releases

Lien waivers are documents in which potential lien claimants agree to waive or release their lien rights in exchange for payment. General contractors and property owners require waivers as protection against paying for work that might later be liened by unpaid subcontractors or suppliers.

Four types of lien waivers exist. Conditional waivers on progress payment state that the claimant waives lien rights for work through a specific date if payment is received. These are given before payment and become effective only when the check clears. Unconditional waivers on progress payment state that lien rights are waived for work through a specific date immediately upon execution, regardless of whether payment is received. These should only be signed in exchange for simultaneous payment.

Conditional waivers on final payment waive all lien rights for the entire project if final payment is received. These are used at project completion before final payment is made. Unconditional waivers on final payment immediately waive all lien rights for the entire project upon execution. These should only be signed after receiving final payment.

California, Florida, Georgia, Massachusetts, Michigan, Mississippi, Missouri, Nevada, Texas, Utah, and Wyoming have statutory lien waiver forms. Using the statutory forms in these states ensures compliance with legal requirements. Creating custom waiver language is risky because courts in statutory form states strictly construe waivers against the party requesting them.

Many general contractors’ form waivers contain dangerous “broad form” language releasing not only lien rights but also all claims for extras, delays, acceleration, and other disputed amounts. Language stating the signer “releases all claims of every kind and nature arising out of or related to the project” goes far beyond a simple lien waiver. This type of release can forfeit valid claims for additional work that the subcontractor performed but has not yet been paid for.

Pennsylvania law prohibits subcontractors from waiving lien rights except in narrow circumstances. Section 507 of Pennsylvania’s Mechanics’ Lien Law states “a waiver by a subcontractor of lien rights is against public policy, unlawful and void, unless given in exchange for payment” or unless part of a settlement resolving a bona fide dispute. Contract provisions requiring advance waiver of lien rights are unenforceable in Pennsylvania.

North Carolina enacted legislation in 2022 limiting broad-form lien waivers. Under new N.C. Gen. Stat. § 44A-12.2, provisions requiring lien waivers as a condition of receiving interim or progress payments are void and unenforceable unless “limited to the specific interim or progress payment actually received.” This prevents owners and general contractors from using withholding of progress payments as leverage to extract waivers covering future work not yet paid for.

When presented with a lien waiver, carefully review what time period is covered, what payment amount is referenced, and whether the waiver is conditional or unconditional. Never sign an unconditional waiver before receiving payment. If the waiver language extends beyond lien rights to release other claims, negotiate to limit it to the specific payment being made.

Enforcing Mechanics Liens Through Foreclosure

Filing a mechanics lien establishes your claim but does not automatically result in payment. If the property owner refuses to pay or disputes the lien, you must file a lawsuit to foreclose the lien. This foreclosure action asks the court to order the property sold and the proceeds applied to pay your claim.

The deadline to file a foreclosure lawsuit is strictly enforced and varies significantly by state. California requires filing within 90 days after recording the lien. Arizona allows 6 months. Washington allows 8 months. Texas allows 2 years. Florida allows 1 year. Missing the enforcement deadline causes the lien to expire and become unenforceable even though it remains of record until formally released.

The foreclosure complaint must name all necessary parties as defendants. At minimum this includes the property owner and the general contractor. Other parties with interests in the property, such as mortgage lenders and other lien claimants, should also be named. Failure to join necessary parties can result in dismissal of the foreclosure action.

After filing the complaint, you must record a lis pendens (notice of pending litigation) with the county recorder where the property is located. This document places public notice that a lawsuit affecting title to the property is pending. The lis pendens prevents the owner from selling or refinancing the property without disclosing the litigation, which effectively blocks transactions until the case is resolved.

Most foreclosure lawsuits settle before trial. The mere existence of a lawsuit with an associated lis pendens creates pressure on property owners to resolve the dispute. Owners who want to sell, refinance, or simply clear title must either pay the claim, prove the claim is invalid, or post a bond to transfer the lien from the property to the bond.

If the case proceeds to trial, you must prove: (1) you provided labor or materials to the project, (2) you followed all notice and filing requirements, (3) the owner or contractor agreed to the work being performed, (4) you completed the work according to the agreement, and (5) the amount you claim is accurate and owed. Documentary evidence including contracts, invoices, delivery receipts, photographs, and testimony from workers establishes these elements.

If you prevail, the court enters judgment in your favor and orders foreclosure and sale of the property. A public auction is scheduled where the property is sold to the highest bidder. Proceeds from the sale are distributed to lienholders in order of priority. Mechanics liens generally have priority over mortgages recorded after construction began, so you may be paid before the lender.

In the rare circumstance where the property is actually sold at foreclosure auction, the winning bidder receives title to the property free of the lien. The previous owner loses the property. This dramatic remedy explains why most cases settle—property owners do not want to risk losing their property over construction payment disputes.

An alternative to full foreclosure is for the property owner to post a “release of lien bond” or “discharge of mechanics lien bond.” These surety bonds transfer the lien from the property to the bond itself. The bond amount is typically 125% to 150% of the lien amount. Once the bond is posted and a certificate of release is recorded, the lien is removed from the property. The claimant then pursues their claim against the bond rather than the property.

Frequently Asked Questions

Can a second-tier subcontractor file a mechanics lien?

Yes. Most states allow second-tier subcontractors (those contracting with first-tier subcontractors rather than directly with general contractors) to file mechanics liens. However, some jurisdictions like DC restrict liens to parties contracting with owners or prime contractors. Check your state’s specific lien statute.

What happens if I don’t send a preliminary notice?

You lose lien rights. In states requiring preliminary notices, failure to send the notice within the statutory deadline (typically 20-45 days after starting work) completely eliminates your ability to file a mechanics lien. Some states allow late notices but only protect work performed within 20 days before the late notice.

Can property owners force me to waive lien rights before paying me?

No. Many states prohibit advance waivers of lien rights as against public policy. You can only waive lien rights for specific payments actually received. Unconditional waivers should only be signed after payment clears. Contract provisions requiring blanket advance waivers are unenforceable in Pennsylvania, North Carolina, and other states.

How long does a mechanics lien last?

90 days to 2 years depending on state. After filing a lien, you must file a foreclosure lawsuit within the enforcement deadline or the lien expires. California requires suit within 90 days. Arizona allows 6 months. Texas allows 2 years. Missing the enforcement deadline makes the lien unenforceable even though it remains recorded.

Can I file a lien on a government building?

No. Publicly owned property is immune from mechanics liens. For federal projects over $100,000, subcontractors have Miller Act payment bond claims. State and local public projects have similar “Little Miller Act” bond requirements. You file claims against the payment bond rather than liening government property.

What is the Miller Act?

Federal law requiring payment bonds. The Miller Act (40 U.S.C. §§ 3131-3134) requires prime contractors on federal construction projects exceeding $100,000 to post payment bonds. First-tier and second-tier subcontractors can sue the bond for non-payment. Second-tier claimants must send written notice to the prime contractor within 90 days.

Do I need a lawyer to file a mechanics lien?

Not required but highly recommended. Lien statutes are technical and strictly interpreted. Minor errors in filing, service, or content invalidate liens. Foreclosure lawsuits require legal expertise. Many contractors successfully file simple liens themselves, but legal review before filing prevents costly mistakes that forfeit payment rights.

Can I include attorney’s fees in my lien amount?

Check your contract and state law. Some states allow including attorney’s fees if the contract between the parties provides for fee recovery. Other states prohibit including fees in the lien amount. Inflating liens by including fees not authorized by statute or contract can result in courts declaring the entire lien fraudulent.

What if the owner already paid the general contractor in full?

Depends on when the owner was notified. In many states, subcontractors can only recover amounts the owner still owes the general contractor when the owner receives notice of the subcontractor’s claim. If the owner paid the general contractor before receiving your preliminary notice or lien, your claim may be limited or worthless.

Can I file a lien for equipment rental?

Yes in most states. Equipment rental companies that lease tools, machinery, and equipment for use on construction projects generally have lien rights. The equipment must be used on the project itself. Off-site rental of equipment used for general business purposes rather than a specific project typically does not create lien rights.

What is a Notice of Completion and why does it matter?

Document that shortens lien filing deadlines. Property owners file Notices of Completion with county recorders after project completion. Recording this document reduces lien filing deadlines from 90 days to 30 or 45 days for subcontractors in many states. Missing a shortened deadline caused by a Notice of Completion you didn’t know about eliminates lien rights.

Can suppliers file mechanics liens?

Yes if materials become part of the improvement. Material suppliers who provide lumber, concrete, steel, fixtures, and other materials that become permanent parts of the building have lien rights. Suppliers to suppliers generally do not. Suppliers of consumable items like fuel or temporary materials typically cannot lien the property.

What is retainage and how does it affect my lien rights?

Contract provision withholding payment until completion. Retainage refers to amounts a contractor withholds from payment (often 10%) until project completion or issue resolution. Contractual retainage extends lien filing deadlines in many states. Statutory retainage required by law must be withheld by property owners to protect against subcontractor claims.

Can I file a lien after the project is finished?

Yes within the filing deadline. Lien filing deadlines begin running from specific trigger dates (often project completion or your last day of work). You typically have 30-180 days after the trigger date depending on the state. Filing too early (while you’re still working) can invalidate the lien in some states.

What happens if I file a lien and then get paid?

You must release the lien. Once payment is received, you are required to execute and record a lien release removing the lien from the property records. Failing to promptly release a lien after being paid can result in the owner suing you for wrongfully maintaining the lien. You may be liable for the owner’s attorney’s fees.
