Commercial cleaning costs $0.08 to $0.20 per square foot per visit for most office environments, based on HomeAdvisor and HomeGuide national cost data. A 2,500-square-foot office cleaned three times per week typically runs $800 to $1,500 per month. Specialized environments - medical offices, restaurants, industrial facilities - can run two to three times the standard rate because of additional protocols and labor.
What does commercial cleaning cost on average?
HomeAdvisor reports the national average for commercial cleaning at $0.11 per square foot for standard office environments. HomeGuide's 2024 commercial cleaning data puts the range at $0.08 to $0.20 per square foot depending on cleaning frequency and facility type.
Monthly cost depends on square footage and how many visits per week are included. More visits per month means more labor hours, but the per-visit rate may be lower because the cleaner travels to an established account rather than a new site each time.
| Office size (sq ft) | Monthly cost, 2x/week | Monthly cost, 3x/week | Monthly cost, daily |
|---|---|---|---|
| Up to 1,000 | $200 - $350 | $300 - $500 | $450 - $700 |
| 1,000 - 2,500 | $350 - $600 | $500 - $850 | $700 - $1,200 |
| 2,500 - 5,000 | $600 - $1,000 | $850 - $1,400 | $1,200 - $2,000 |
| 5,000 - 10,000 | $900 - $1,500 | $1,300 - $2,200 | $2,000 - $3,500 |
| 10,000 - 25,000 | $1,500 - $3,000 | $2,200 - $4,200 | $3,500 - $7,000 |
Estimates from HomeAdvisor and HomeGuide national surveys. High-cost metro areas (New York, San Francisco, Boston) typically run 25 to 50 percent above these figures.
Minimum charges apply with most commercial cleaning companies. Few will take on a contract below $200 per month, even for a very small office.
Office cleaning rates per square foot
Per-square-foot pricing is the most common billing structure for ongoing commercial cleaning contracts. The rate accounts for all labor, supplies, and travel to an established account.
Baseline rates by facility type, based on ISSA industry research and HomeGuide data:
| Facility type | Typical rate per sq ft per visit |
|---|---|
| Standard office space | $0.08 - $0.14 |
| Medical office / clinic | $0.18 - $0.40 |
| Restaurant / food service | $0.15 - $0.30 |
| Retail store | $0.10 - $0.18 |
| Warehouse / light industrial | $0.05 - $0.10 |
| School or childcare facility | $0.12 - $0.22 |
Medical environments carry a higher rate because cleaners must follow biohazard protocols, use hospital-grade disinfectants, and in some cases hold OSHA bloodborne pathogen training. Restaurants have grease and health-code compliance requirements that add labor time. Warehouses are often less intensive per square foot because the work is primarily sweeping large floor areas with minimal surfaces.
Monthly cost by office size and cleaning frequency
Frequency is one of the biggest variables in commercial cleaning cost. More visits per month means more labor, but the per-visit cleaning time is shorter because soil does not accumulate as much between visits.
A useful way to estimate: take the square footage times the per-visit rate, then multiply by visits per month. For a 3,000-square-foot office at $0.11 per square foot cleaned 12 times per month (three times per week): 3,000 x $0.11 x 12 = $3,960 per month. That is the rough labor cost basis; overhead and profit add 20 to 40 percent on top.
In practice, commercial cleaners quote total monthly contract prices rather than this calculation explicitly. But the math helps you evaluate whether a quote is in a reasonable range.
What affects commercial cleaning rates?
Several factors push a commercial cleaning quote above or below the baseline per-square-foot rate:
Location. Labor costs drive significant variation. A quote for a 5,000-square-foot office in Dallas will look substantially different from the same office in New York City or San Francisco.
After-hours requirement. Most businesses prefer cleaning after hours to avoid disruption. Night-shift cleaning is standard and usually included in the quoted rate, but some providers add a small surcharge for weekend or holiday coverage.
Restroom count and size. Restrooms require the most intensive cleaning per square foot and the most frequent attention. A 2,000-square-foot office with four restrooms costs more to maintain than the same office with one.
Specialized areas. Break rooms, kitchens, server rooms, and reception areas require more time than standard office space. If your facility has a commercial kitchen or food-prep area, expect higher rates.
Security clearance requirements. Government contractors and facilities handling sensitive materials sometimes require cleaners to hold background clearance. This narrows the pool of eligible providers and typically adds a premium.
Move-in, move-out, and deep cleaning. Periodic deep cleans - floor stripping and waxing, carpet extraction, window cleaning - are usually priced separately from the routine maintenance contract. Budget for these as one to two additional visits per year.
Janitorial contracts vs. one-time commercial cleaning: which costs more?
One-time commercial cleaning - for a post-renovation cleanup, a move-in clean for a new space, or a single event cleanup - is priced at a higher per-visit rate than an ongoing contract. Contract pricing gives the cleaning company predictable revenue and scheduling efficiency; the savings are passed through in a lower per-visit rate.
A one-time commercial clean for a 2,500-square-foot office might cost $400 to $700 as a standalone job. The same scope under an ongoing three-visit-per-week contract runs $150 to $250 per visit, or less.
If your need is truly one-time, the standalone price is fair. If you expect to need cleaning regularly, a contract is almost always the better value.
What is included in a standard office cleaning contract?
Standard commercial cleaning contracts cover routine maintenance tasks that keep a working environment sanitary and presentable. What is included varies by provider, so reviewing the scope of work section in the contract is essential before signing.
Typical inclusions in a standard contract:
- Emptying all trash receptacles and replacing liners
- Cleaning and sanitizing all restrooms (toilets, sinks, mirrors, floors)
- Wiping kitchen and break-room surfaces, cleaning sink, wiping microwave exterior
- Vacuuming carpeted areas
- Sweeping and mopping hard floors
- Dusting surfaces (desks, windowsills, filing cabinets) where accessible
- Wiping down door handles and light switches
- Cleaning glass on entry doors and interior glass partitions
Items typically not included unless specified: internal glass window cleaning, deep carpet extraction, stripping and waxing hard floors, exterior window cleaning, cleanout of kitchen appliance interiors, cleaning of electronic equipment. These are usually available as add-ons at an additional flat rate.
How to get competitive bids and evaluate them fairly
Getting three bids from comparable providers gives you a reasonable picture of local market rates for your scope. Make sure each bidder is quoting on identical terms: same square footage, same frequency, same scope of work. A quote that looks low may exclude restroom supplies or after-hours access fees that others include.
Ask each provider to walk through the contract's scope of work section with you. The vaguest contracts create the most disputes. Clauses like "clean common areas as needed" are meaningless - you want explicit lists.
For context on evaluating any cleaning service, including verification of insurance and bonding credentials, see our guide to how to choose a cleaning service. If you are also managing residential cleaning for a home office or similar arrangement, average house cleaning rates provides the residential pricing baseline.
Ask for References from Similar-Size Clients
When evaluating commercial cleaning companies, ask for references from clients with facilities similar to yours in size and industry. A company that excels at cleaning a 500-person corporate campus may not be the right fit for a 10-person professional services office - different scale, different staffing model, different attention to detail.
Commercial cleaning is a commodity service in most markets, which means price competition is real and bids can vary significantly for identical scope. Understanding the per-square-foot baseline for your facility type, confirming scope in writing, and comparing contract terms rather than just total monthly price will get you to a fair arrangement.

Frequently asked questions
What does commercial cleaning cost per square foot?
Commercial cleaning typically costs $0.08 to $0.20 per square foot per cleaning visit, based on HomeAdvisor and HomeGuide national cost data. Offices with specialized requirements - medical facilities, food-service environments, high-security areas - can run $0.25 to $0.50 per square foot due to stricter protocols and more intensive labor.
How often should an office be professionally cleaned?
Most offices benefit from at least three cleaning visits per week. High-traffic offices with 20 or more staff often need daily cleaning to maintain sanitary standards for restrooms, kitchen areas, and common surfaces. Low-traffic offices with fewer than 10 staff can often manage with twice-weekly cleaning. Conference rooms and reception areas need more attention than private offices.
What is the difference between janitorial service and commercial cleaning?
Janitorial service is typically an ongoing maintenance contract covering routine tasks - emptying trash, cleaning restrooms, vacuuming floors, wiping surfaces. Commercial cleaning often refers to a broader or one-time scope, including deep cleaning, floor stripping and waxing, or post-construction cleanup. In practice, many companies use the terms interchangeably.
Do commercial cleaners bring their own supplies and equipment?
Most commercial cleaning companies supply all cleaning products, equipment, and consumables. Some contracts include restroom supplies (paper towels, soap) as an add-on; others expect the client to supply them. Confirm this in the contract. Specialty equipment like floor buffers and carpet extractors are typically provided by the cleaner.
Is it cheaper to hire a cleaning company or in-house staff?
For offices under 10,000 square feet cleaned three times per week or less, outsourcing to a commercial cleaning company is typically more cost-effective than hiring in-house. An in-house cleaner at $18 to $22 per hour for 20 hours per week costs $1,440 to $1,760 monthly before benefits. A cleaning company for the same scope often runs $800 to $1,200 per month.
What certifications should a commercial cleaner have?
ISSA certification (from the International Sanitary Supply Association) is the most recognized credential in the industry. IICRC certification applies to carpet and restoration work. For medical or food-service environments, ask about biohazard handling training and compliance with OSHA bloodborne pathogen standards. General liability insurance and workers' compensation are baseline requirements.
