How Much Should I Charge to Clean an Office Building? (w/Examples) + FAQs

Most office cleaning contracts in the United States price between $0.05 and $0.25 per square foot per visit, or $25 to $90 per hour, with monthly contracts for a typical 5,000–10,000 square foot office landing between $1,200 and $6,500. The exact number depends on building class, frequency, scope, region, labor cost, and the legal classification of your workers under the Fair Labor Standards Act.

The pricing problem is rarely about what the market pays. The problem is that cleaning is governed by a tangle of federal wage rules, state janitorial licensing statutes, OSHA bloodborne pathogen standards, EPA Safer Choice chemical rules, and IRS worker-classification tests that quietly raise your true cost per hour. Underprice and you lose money on every visit, misclassify a worker and you owe back wages, taxes, and penalties.

According to the Bureau of Labor Statistics, janitors and building cleaners earned a median wage of $16.57 per hour in 2024, with total loaded labor cost (taxes, insurance, supplies, supervision) typically running 1.45x to 1.75x the base wage.

Here is what you will learn in this guide:

• 💵 How to calculate a profitable bid using square footage, productivity rates, and loaded labor cost
• 🏢 Real pricing examples for Class A, Class B, Class C, medical, and coworking offices
• ⚖️ The federal and state legal traps (FLSA, IRS, OSHA, EPA, prevailing wage) that destroy margins

• 🚫 The seven most expensive bidding mistakes new cleaners make on commercial accounts

The Core Pricing Question Answered First

You should charge enough to cover loaded labor, supplies, equipment depreciation, insurance, overhead, and a net profit of 10% to 25%. For most U.S. office buildings in 2026, that translates to $0.07 to $0.18 per square foot per cleaning for standard nightly janitorial, and $0.18 to $0.40 per square foot for medical or specialty offices. Hourly rates for solo cleaners typically run $25 to $50, while crew-based commercial firms bill $45 to $90 per hour to the customer.

The number you quote must always answer three questions at once. First, does it beat your break-even cost? Second, does it match the building’s tier and the local market? Third, does it leave room for the legal costs of running a compliant cleaning business under the IRS independent contractor rules and the FLSA minimum wage and overtime rules?

Most new cleaners skip the second and third questions and lose money for a year before they realize it. The fix is to build pricing from the bottom up using a documented productivity rate, then test it against the top-down market rate.

The Four Main Pricing Models for Office Cleaning

There are four pricing models used in U.S. commercial cleaning, and the right one depends on the building, the scope, and the predictability of the work. Picking the wrong model is the single fastest way to lose a contract or lose your shirt on it. Each model carries its own legal risk profile under federal wage law and state contract law.

A working bid almost always uses one model as the headline price and a second model as the internal sanity check. For example, you may quote a flat monthly rate to the client while internally building the price from a per-square-foot productivity rate.

Per Square Foot Pricing

Per square foot pricing charges a set rate for every cleanable square foot of the building, usually expressed per visit or per month. The plain-English explanation is simple: you measure the floor, multiply by a rate, and that is the price. The standard 2026 range is $0.05 to $0.25 per square foot per visit for general office work, per ISSA Cleaning Industry Management Standard benchmarks.

The consequence of getting the rate wrong is brutal. A 50,000 square foot building priced at $0.04 per square foot instead of $0.08 costs you $2,000 every single visit in lost margin. Over a five-night-per-week contract that is $520,000 in lost revenue per year.

A real-world example: Maria runs a two-person crew and bids a 20,000 square foot Class B office at $0.09 per square foot, five nights per week. Her monthly invoice is 20,000 x $0.09 x 22 visits = $39,600, and her loaded labor and supply cost is roughly $26,000, leaving a 34% gross margin.

A common misconception is that bigger buildings should always cost more per square foot. The opposite is true. Larger buildings get a lower rate per square foot because productivity rises with open floor plate and reduced setup time per visit.

Hourly Pricing

Hourly pricing charges a billable rate for every hour worked on site, typically used for one-time cleans, small offices under 3,000 square feet, or accounts where scope changes weekly. The 2026 range is $25 to $50 per hour for solo operators and $45 to $90 per hour for insured commercial crews, according to data published by the Building Service Contractors Association International.

The consequence of underpricing your hour is a slow death. If your loaded labor cost is $24 per hour and you bill $30, a single workers’ compensation claim or one unpaid invoice wipes out a quarter of profits.

A real-world example: David cleans a 2,500 square foot accounting firm three nights per week at $40 per hour, two hours per visit, for $240 weekly or roughly $1,040 monthly. His take-home after supplies, fuel, and self-employment tax is about $620.

A common misconception is that hourly billing protects the cleaner. It does the opposite when the client pressures you to “finish faster,” because you are now incentivized to cut corners and lose the contract on quality.

Flat Monthly Rate

A flat monthly rate bundles all visits, supplies, and routine extras into one predictable number the client pays every month. This is the most common model for nightly office janitorial because facility managers love budget certainty. The 2026 range for typical office buildings runs $1,200 to $6,500 per month for properties between 5,000 and 25,000 square feet.

The consequence of building a flat rate without a square-foot or hour-based foundation is scope creep. Clients add tasks, attendance days, or square footage and you absorb it because the contract did not define a unit price.

A real-world example: Tasha signs a 12,000 square foot tech startup at $3,400 per month, five nights per week, with a clearly defined scope and a $0.13 per square foot adjustment clause for any added space. Six months later the client adds 4,000 square feet, and Tasha’s automatic adjustment adds $520 per month.

A common misconception is that flat-rate clients want the lowest price. Most facility managers want the most defensible price, meaning one that survives an audit by their finance team.

Per Cleanable Square Foot and Productivity Rate

Per cleanable square foot pricing excludes spaces that do not need cleaning (mechanical rooms, vacant suites, storage) and applies a productivity rate measured in square feet per hour. ISSA publishes 612 standardized cleaning time tasks, with rates from 1,000 sq ft per hour for detailed restroom work to 20,000 sq ft per hour for open-area dust mopping.

The consequence of skipping productivity rates is that you can never defend your price. When a client asks “why $4,200 per month?” you need to show how many labor hours you priced and at what wage and burden.

A real-world example: Carlos prices a 30,000 square foot building at a productivity rate of 3,500 sq ft per hour, giving 8.6 labor hours per visit. At a loaded labor cost of $28 per hour plus 20% overhead and 15% profit, his price is roughly $365 per visit or $8,030 per month at 22 visits.

A common misconception is that productivity rates are only for big firms. Solo operators benefit more because every wasted hour comes straight out of their take-home pay.

How Building Class Changes Your Price

Office buildings are graded by BOMA International as Class A, Class B, or Class C, and the class drives both the cleaning standard expected and the price the market will support. Cleaning a Class A high-rise to Class C standards gets you fired in 30 days, and cleaning a Class C strip-mall office to Class A standards loses you the bid because you are too expensive.

Each class has different finishes, fixtures, foot traffic, and contract expectations. Each also has different insurance and bonding requirements written into the standard commercial lease abstract.

Class A Buildings

Class A buildings are top-tier properties with premium finishes, high-end tenants, and detailed cleaning specifications. They expect daytime porter service, day-cleaning programs aligned with LEED O+M v4.1 green-cleaning credits, and full transparent reporting. Pricing typically runs $0.12 to $0.25 per square foot per visit, and contracts often require $2 million general liability insurance and a $25,000 janitorial bond.

The consequence of underpricing a Class A building is that you cannot afford the labor density required to meet specifications. A real-world example: Priya wins a 75,000 square foot Class A tower at $0.15 per square foot, five nights per week, generating roughly $24,750 per month. Her crew of four runs three hours per night, all W-2 employees, fully covered under workers’ compensation insurance.

A common misconception is that Class A clients always pay top dollar. They pay top dollar only when your bid documents prove you can deliver to spec, with measurable APPA cleaning levels attached to the scope.

Class B Buildings

Class B buildings are functional, well-maintained, mid-tier offices that house professional services firms, regional companies, and government tenants. Pricing runs $0.07 to $0.13 per square foot per visit, with monthly contracts on 10,000–40,000 square foot buildings between $2,200 and $14,000. These buildings expect nightly cleaning, weekly detail tasks, and quarterly carpet care.

The consequence of overpricing Class B work is losing the bid to a regional competitor by 15%. A real-world example: Marcus prices a 22,000 square foot Class B medical office building at $0.10 per square foot, five nights per week, for roughly $48,400 per month. His crew handles common areas only; tenants pay for in-suite cleaning separately.

A common misconception is that Class B does not need detailed scope documentation. It does, because Class B clients are the most likely to compare bids line by line.

Class C Buildings

Class C buildings are older, basic-finish offices, often in secondary or tertiary markets, with cost-sensitive tenants. Pricing runs $0.05 to $0.09 per square foot per visit, with most monthly contracts between $600 and $2,800. Frequencies are usually two or three nights per week rather than five.

The consequence of misjudging Class C scope is that thin margins disappear instantly when you add a single unbudgeted hour. A real-world example: Aisha cleans a 6,000 square foot Class C insurance office three nights per week at $0.07 per square foot, generating about $1,820 per month, working solo at 90 minutes per visit.

A common misconception is that Class C clients accept lower quality. They accept lower frequency but expect the same baseline cleanliness during the visits they pay for.

Specialty Office Pricing

Some offices fall outside the standard Class A/B/C rubric and require specialty pricing because of regulation, hazard, or schedule. Medical offices fall under OSHA’s Bloodborne Pathogens Standard 29 CFR 1910.1030, which requires written exposure control plans and EPA-registered List N disinfectants for many surfaces. Coworking spaces require daytime presence and high-touch disinfection cycles every two to three hours.

Government offices may trigger the McNamara-O’Hara Service Contract Act, which sets prevailing wages and fringe benefits the contractor must pay. Failure to pay SCA wages results in back wages, debarment from federal contracts for three years, and possible criminal prosecution for willful violations.

Medical Office Buildings

Medical office pricing runs $0.18 to $0.40 per square foot per visit because of disinfection protocols, biohazard handling, and HIPAA-compliant trash handling. A 10,000 square foot medical office often prices between $5,500 and $12,000 per month for five-night service.

The consequence of pricing a medical office at standard office rates is operational disaster: you cannot afford the disinfectant chemistry, the dwell-time labor, or the OSHA-mandated Hepatitis B vaccination program. A real-world example: Lena prices a 12,000 sq ft pediatric clinic at $0.28 per square foot five nights per week for $36,960 per month, builds in a $400 monthly chemical line item, and pays a $0.75 per hour shift differential.

A common misconception is that medical cleaning equals “cleaning plus a little bleach.” Medical cleaning is a regulated activity with documentation, training, and chain-of-custody requirements that materially raise loaded labor cost.

Coworking and Tech Offices

Coworking and tech offices price between $0.10 and $0.20 per square foot because of constant traffic, kitchen and beverage service areas, and nonstandard hours. They require both a nightly clean and a daytime porter for restroom restocks, dish handling, and reception support.

A real-world example: Jamal contracts a 15,000 square foot coworking space at $0.14 per square foot, plus a $3,200 monthly day-porter line item, totaling about $49,400 per month. His porter is a W-2 employee paid $19 per hour with full payroll burden.

A common misconception is that coworking space owners want lower prices. They want predictable, documented cleanliness because clean space is the product they sell to members.

Three Realistic Bid Scenarios

The fastest way to internalize pricing is to walk through full bids on three different buildings. Each scenario below uses 2026 labor rates, a 1.55x burden multiplier, and a 15% net profit target. Each table is a side-by-side view of the bid line items and the resulting financial outcome.

Scenario 1: 8,000 Sq Ft Class B Law Firm, Five Nights Per Week

Scenario 2: 25,000 Sq Ft Class A Corporate HQ, Five Nights Per Week

Scenario 3: 6,000 Sq Ft Medical Clinic, Three Nights Per Week

Federal Laws That Set Your Floor Price

Three federal frameworks set a hard floor under what you can charge: the Fair Labor Standards Act, the IRS worker classification rules, and OSHA general industry standards. Skipping any of these does not save you money long term; it only delays the back-pay, penalty, or settlement check.

The plain-English explanation is that you must pay at least minimum wage, pay overtime after 40 hours, classify W-2 vs 1099 correctly, and maintain a safe workplace. The consequence of ignoring these is back wages, liquidated damages equal to the back wages, civil penalties up to $2,515 per violation under FLSA enforcement, and personal liability for owners.

A real-world example: a janitorial company in Texas was ordered to pay $1.6 million in back wages to 376 cleaners after a Wage and Hour Division investigation found systematic overtime miscalculation. A common misconception is that paying “cash to subcontractors” sidesteps these laws. It does not, because the economic realities test usually finds that nightly office cleaners working a fixed route are W-2 employees.

The FLSA Overtime Rule

FLSA requires time-and-a-half for all hours worked over 40 in a workweek by non-exempt employees. Most office cleaners are non-exempt and therefore eligible for overtime. The consequence of skipping overtime is double damages plus attorney fees in any private suit.

A real-world example: Roberto schedules four cleaners at 38 hours each but routinely lets them stay 45 minutes late. Without overtime tracking, after one year he owes roughly $8,400 per cleaner in unpaid overtime and an equal amount in liquidated damages.

A common misconception is that “salary” cleaners are overtime-exempt. Janitorial salary positions almost never meet the FLSA executive, administrative, or professional duties test.

The IRS 1099 vs W-2 Test

The IRS uses a three-factor common law test covering behavioral control, financial control, and the relationship of the parties. The plain-English explanation: if you set the schedule, supply the equipment, and direct the work, the cleaner is your employee. The consequence of misclassification is back FICA, back federal unemployment, back state unemployment, and a 100% penalty under IRC Section 6672.

A real-world example: Nancy hires five “1099 contractors” to clean her route at $18 per hour. After an IRS audit, she owes back employer taxes of roughly $11,400 per worker per year plus penalties.

A common misconception is that signing a “1099 contractor agreement” controls the answer. The agreement is one piece of evidence and almost always loses to the actual working relationship.

State Law Nuances You Cannot Ignore

State law layers extra obligations on top of federal rules, and three states deserve a special call-out: California, New York, and Illinois. Each has a janitorial-specific statute that raises your true cost per cleaning hour.

California’s Property Service Workers Protection Act (AB 1978) requires janitorial employers to register with the Division of Labor Standards Enforcement, provide sexual harassment training, and maintain a public registry. New York’s Wage Theft Prevention Act requires written wage notices in the employee’s primary language at hire and any pay change. Illinois requires janitorial business licensing under 225 ILCS 422 and bonding for any commercial cleaning company.

The consequence of ignoring state janitorial statutes is denial of contract eligibility. Most facility managers will not sign with an unregistered or unbonded contractor in regulated states.

A real-world example: Sofia expands from Nevada into California and bids a 40,000 square foot Oakland office. Her bid is rejected solely because she has not completed California’s janitorial registration.

A common misconception is that registration is optional for small operators. In California, every employer of janitorial workers must register, regardless of size.

The Mistakes To Avoid

These are the most expensive bidding mistakes a new commercial cleaner can make. Each one quietly shrinks margins and can end the contract, the business, or both.

• Pricing without a measured walk-through. The negative outcome is missing whole zones (mechanical, garages, exterior glass), then absorbing them at zero margin.
• Using a 1.0x labor multiplier instead of 1.45x–1.75x. The negative outcome is forgetting payroll taxes, workers’ comp, and insurance, then losing 30% of every dollar.
• Misclassifying cleaners as 1099 contractors. The negative outcome is IRS, DOL, and state liability stacking three layers deep.
• Skipping a written scope of work. The negative outcome is uncontrolled scope creep that adds hours you cannot bill back.
• Bidding without a cancellation clause. The negative outcome is buying equipment and uniforms for a 24-month payback on a contract the client cancels in 30 days.
• Ignoring insurance certificate requirements. The negative outcome is being barred from the building on day one for missing additional-insured endorsement.
• Pricing below local prevailing wage on government work. The negative outcome is debarment from federal contracts for three years under SCA.
• Forgetting consumables (paper, soap, liners) escalation. The negative outcome is eating 4–8% of revenue in supply inflation each year.
• Not adjusting for LEED green-cleaning chemistry. The negative outcome is failing the building’s sustainability audit and losing the contract.
• Quoting verbally without a signed agreement. The negative outcome is unenforceable terms under most state statute of frauds provisions for service contracts over a year.

Do’s and Don’ts of Office Cleaning Pricing

A short, sharp checklist you can apply to every bid before you send it.

• Do measure the building yourself, because broker-supplied square footage is wrong about 20% of the time.
• Do build the price from loaded labor up, because that protects margin when wages rise.
• Do include a CPI-linked annual escalator, because flat three-year contracts erode 6%–9% in real terms.
• Do require a 60-day cancellation clause, because it lets you recover startup investments.
• Do carry $1M–$2M general liability, because most Class A and Class B buildings require it as a baseline.
• Don’t quote before walking the building, because surprises always cost more than you estimated.
• Don’t assume nightly frequency, because three-night and four-night schedules are common in Class B and C.
• Don’t ignore state janitorial registration, because unregistered firms cannot legally bid in many states.
• Don’t bundle supplies into a flat rate without an adjustment clause, because consumable inflation will gut your margin.
• Don’t forget supervisor labor, because a working supervisor is required for any crew of three or more.

Pros and Cons of Each Pricing Model

Each pricing model has structural strengths and structural weaknesses. A working bid often blends two of them.

• Per square foot pro: Easy to defend to a finance team that understands real estate metrics.
• Per square foot con: Hides labor risk if the building has unusual layouts or fixtures.
• Hourly pro: Protects you on unpredictable scope, because every minute is billable.
• Hourly con: Caps revenue at your slowest worker’s pace and invites client micromanagement.
• Flat monthly pro: Predictable revenue and predictable client invoices.
• Flat monthly con: Absorbs scope creep unless the contract has a unit-rate adjustment clause.
• Productivity rate pro: Defensible to ISSA and BSCAI standards, audit-proof.
• Productivity rate con: Requires real measurement skills and ISSA training time.
• Hybrid (flat + unit) pro: Gives the client predictability and gives you protection.
• Hybrid (flat + unit) con: Requires a longer contract and more legal review up front.

The Step-by-Step Bid Process

A clean, repeatable bid process keeps you out of trouble and out of money-losing contracts. Each step has its own decision points and its own consequences.

Step 1: Walk the Building and Measure

Walk every floor with the property manager or facility lead. Measure cleanable square footage using a laser distance meter and exclude mechanical rooms, vacant suites, and exterior areas not in scope. The consequence of skipping the walk is pricing the wrong number of square feet, restrooms, or floor types.

Step 2: Document the Scope

Write a scope of work that lists every task by frequency: nightly, weekly, monthly, quarterly, annually. Reference APPA Custodial Staffing Guidelines for objective cleanliness levels 1 through 5. The consequence of vague scope is endless free work.

Step 3: Calculate Loaded Labor

Take the base wage and multiply by your burden factor. Burden includes payroll taxes (FICA 7.65%, FUTA 0.6%, SUTA varies), workers’ comp (typically 4%–9% for janitorial code 9014), general liability, health insurance if offered, and paid time off. The consequence of using base wage instead of loaded labor is a guaranteed margin gap.

Step 4: Build Supplies, Equipment, and Overhead

Add 4%–8% of revenue for consumables, 2%–4% for equipment depreciation, and 8%–15% for overhead. The consequence of skipping these lines is calling them “profit” by accident and then having no actual profit.

Step 5: Add Profit and Submit a Written Bid

Apply 10%–25% net profit, format the bid with line items, and require a signed contract before starting. The consequence of starting without signature is unenforceable scope and possible non-payment.

Insurance and Bonding Minimums

Most commercial offices require $1,000,000 per occurrence and $2,000,000 aggregate in commercial general liability insurance, plus a $10,000 to $25,000 janitorial bond to cover employee theft. Workers’ compensation is mandatory in 49 states (Texas is the exception), and most Class A buildings require $1M employer’s liability and a waiver of subrogation.

The consequence of inadequate insurance is being barred from the building, sued personally for any loss, or losing the entire contract on the first slip-and-fall claim. A real-world example: Eli skips the additional-insured endorsement on a Class A tower contract, a vendor slips on a wet floor, and Eli’s policy denies the claim because the property owner was not named.

A common misconception is that a homeowner’s policy or a personal umbrella covers commercial cleaning work. They do not, and the policy will deny the claim on first review.

Contract Clauses That Protect Margin

The price on the front page of the bid is only as strong as the contract clauses on the back pages. The five most important clauses are scope, term, escalation, cancellation, and indemnity. Each has direct dollar consequences if drafted poorly.

A solid scope clause references the written task list and frequency table, and ties any change to a written change order. A term clause sets a minimum 12 months with auto-renewal, because shorter terms do not justify startup costs. An escalation clause tied to the BLS Consumer Price Index protects against wage and supply inflation. A cancellation clause requires 60 days’ written notice. An indemnity clause limits your exposure to your own negligent acts and excludes the client’s negligence.

A real-world example: Hannah signs a Class B contract with no escalation clause, watches minimum wage rise from $15 to $17.50 over three years, and loses $48,000 in eroded margin by the end of the term.

Frequently Asked Questions

Is $0.10 per square foot a fair price for office cleaning in 2026?

Yes. $0.10 per square foot per visit sits in the middle of the national 2026 range for Class B office cleaning, but you must verify it covers your loaded labor cost in your specific market before quoting it.

Do I need a license to clean office buildings?

Yes. Several states including Illinois, California, and Nevada require janitorial business licensing or registration, and many cities require a general business license, so check with your state’s labor department before bidding.

Can I pay my office cleaners as 1099 contractors?

No. Almost all nightly office cleaners fail the IRS and DOL economic realities tests, so they must be W-2 employees with payroll taxes, workers’ comp, and overtime protection.

Should I include supplies in my monthly price?

Yes. Most commercial clients prefer a fully bundled monthly rate that includes paper goods, soap, and liners, but always include a written annual adjustment clause for consumable inflation.

Is hourly billing better than flat monthly billing?

No. Flat monthly billing is generally better for both sides on routine office work because it gives the client budget certainty and gives you predictable revenue once your scope is documented.

Do I need insurance to bid on office buildings?

Yes. Most commercial properties require $1M–$2M in general liability and a janitorial bond, and you cannot enter many Class A buildings without proof of insurance and an additional-insured endorsement.

Can I charge more for medical office cleaning?

Yes. Medical offices price 50%–100% above standard office rates because of OSHA bloodborne pathogen rules, EPA-registered disinfectants, and HIPAA-compliant trash handling, all of which raise loaded labor cost.

Should my bid include weekend or holiday work?

No. Standard office contracts cover Monday–Friday only, and weekend or holiday work should always be priced as a separate line item at a premium hourly rate.

Is it legal to underbid the prevailing wage on federal contracts?

No. The McNamara-O’Hara Service Contract Act sets minimum wages and fringe benefits on federal service contracts, and underbidding triggers back wages, debarment, and possible criminal penalties for willful violations.

Can I raise prices mid-contract if my labor cost goes up?

Yes. A properly drafted CPI escalation clause or annual review clause lets you raise prices on schedule, but without that clause the original rate is locked for the contract term.

Do I have to pay overtime to my office cleaners?

Yes. Office cleaners are non-exempt under FLSA, so any hours over 40 per workweek must be paid at one-and-a-half times the regular rate, even if the cleaner is paid a salary.

Is a verbal cleaning agreement enforceable?

No. Most state statutes of frauds require a written agreement for service contracts longer than one year, and verbal agreements are nearly impossible to enforce in court without written backup.
