Quick answer: Commercial office cleaning cost in 2026 runs about $0.09 to $0.17 per square foot for a general office, according to ISSA, the cleaning industry association. Priced by the visit, most businesses pay $161 to $402 per cleaning, with an average near $253 (Thumbtack, 2026). Office size, how often the crew comes, and extras like floor care decide where your price lands.

Office cleaning is one of those costs that is easy to overpay or underbudget, because quotes arrive in different shapes: one company prices per square foot, another per hour, a third sends a flat monthly number. Comparing them without knowing what sits behind each figure is how offices end up with a cheap contract that skips the restrooms.

This guide breaks the commercial office cleaning cost down the way the industry does: the published rates per square foot, what a single visit costs by office size, how frequency changes the bill, and which extras add to it. We are Lucy’s Cleaning Home, and we have cleaned homes and offices across Haverhill, the Merrimack Valley and southern New Hampshire for more than 16 years.

What is the average commercial office cleaning cost?

The average office cleaning cost is about $253 per visit, and most businesses pay between $161 and $402, based on Thumbtack’s 2026 pricing data from customer estimates and local professional quotes (Thumbtack, Commercial Cleaning Cost). The full range runs from about $84 for a very small space to about $795 for a large or demanding one. That spread is the most useful single benchmark for commercial office cleaning cost in a small business.

Measured per square foot, the benchmark comes from ISSA, the worldwide cleaning industry association. Its December 2025 guide puts general office cleaning at $0.09 to $0.17 per square foot (ISSA, Commercial Cleaning Rates per Square Foot). ISSA calculates that rate by dividing the monthly contract by the cleanable square footage: a $12,000 monthly contract for 100,000 square feet works out to $0.12.

So the commercial office cleaning cost you see depends on which question you ask:

• Per visit: what one cleaning of your office costs, the way most small offices book
• Per square foot: the rate janitorial contracts use, most useful for larger buildings
• Per hour: labor time, common for small jobs and one-time cleans
• Per month: the recurring contract total, which folds frequency into one number

Commercial office cleaning cost by office size

Office size is the biggest single driver of commercial office cleaning cost, because square footage sets how many hours the crew needs. Thumbtack’s 2026 data shows the typical price per cleaning climbing with every thousand square feet:

Notice that the price per square foot of a single visit is far higher than the ISSA contract rate. That is expected. A one-time or occasional visit carries travel, setup and a heavier first clean, while a recurring contract spreads those costs across many visits.

Why do per-visit prices and per-square-foot rates look so different? They measure different things. Thumbtack’s figures are what customers were quoted for a cleaning job, which in a small office often means one crew for a few hours. ISSA’s rates describe ongoing janitorial contracts, where large, regularly cleaned buildings drive the cost per square foot down. For a small office, the per-visit number is usually the more realistic guide; for a large floor on a recurring contract, start from the per-square-foot rate. If you are still sorting out what these services include, see what is commercial cleaning.

How is commercial office cleaning priced per square foot?

Commercial cleaning prices per square foot depend on the type of facility, because some spaces take more time and stricter protocols per square foot than others. ISSA’s 2025 guide lists these ranges:

Medical offices sit at the top of the range because of infection-prevention requirements. A general office with a few restrooms and a break room usually keeps its commercial office cleaning cost inside the office band, and office cleaning cost per square foot moves toward the upper end when there are more restrooms, more kitchen space or more foot traffic per square foot.

How do I estimate my own rate? Multiply your cleanable square footage by the rate band to get a monthly contract range. At ISSA’s office rates, a 3,000-square-foot office works out to roughly $270 to $510 a month under that method. Treat it as a starting point for comparing quotes, not a price: scope and frequency still change the number, and small offices often pay more per square foot than the band suggests.

What changes your commercial office cleaning cost?

Beyond size, six factors decide where your commercial office cleaning cost lands inside those ranges:

1. Frequency. Daily cleaning costs more per month than weekly, but less per visit, because the space never builds up grime between visits.
2. Scope. Restrooms, a kitchen or break room, and glass partitions take more time than open desk space. A written scope, like our commercial cleaning checklist by zone, is what makes two quotes comparable. Restrooms are usually the biggest line, as our restroom cleaning checklist shows.
3. Floor types. Carpet and hard floors need different equipment and different periodic care.
4. Condition and the first clean. An office that has not been cleaned professionally in months needs a heavier first visit, the same logic as deep cleaning vs regular cleaning at home.
5. Timing. Evening or weekend cleaning outside business hours keeps work uninterrupted, and some companies price it differently.
6. Facility type. Medical, dental and food-service spaces need stricter protocols and cost more per square foot.

Which extras cost the most? Periodic floor care adds the most to a commercial office cleaning cost. ISSA lists carpet cleaning at $0.08 to $0.25 per square foot, scrubbing and recoating hard floors at $0.20 to $0.40, stripping and refinishing at $0.30 to $0.60, and electrostatic disinfection at $0.10 to $0.30 per square foot. These are usually quoted separately from routine cleaning and scheduled a few times a year.

How much does small office cleaning cost?

Small office cleaning for a space under 1,000 square feet averages about $211 per visit, and a space of 1,000 to 2,000 square feet about $376, based on Thumbtack’s 2026 data. Small offices rarely need a daily crew. Two or three visits a week, with restrooms and the break room covered every time, is a common setup.

For a small office, the per-visit commercial office cleaning cost matters more than the per-square-foot rate. Ask each company for the price of one visit at your chosen frequency and what that visit includes. A lower quote that leaves out the restroom or the kitchen is not cheaper; it is less cleaning.

Office cleaning cost per hour vs a flat rate

Thumbtack cites $35 per hour as an example rate for commercial cleaning, and office cleaning cost per hour is the simplest model to understand. The risk is that the total commercial office cleaning cost depends on how long the crew takes, and you cannot see that in advance.

Whatever the model, a commercial office cleaning cost quote should come with the scope in writing. That is the only way to compare an hourly quote against a flat one.

Can an office cleaning cost calculator give me a real price? An office cleaning cost calculator is useful for a rough range: it multiplies your square footage by a rate like the ISSA bands above. It cannot see your restroom count, your floors or how often you want service, so the figure it gives is a budget line, not a quote.

How to get an accurate commercial office cleaning quote

The only accurate commercial office cleaning cost is a quote for your space and your schedule. You get a firmer number, faster, when you send these details up front:

• Cleanable square footage, or the number of rooms and desks
• Number of restrooms and whether there is a kitchen or break room
• How many visits per week, and on which days
• Preferred hours (before opening, evenings or weekends)
• Floor types and any periodic work you want (carpets, floor finish)
• Anything that needs special care, such as a reception area that clients see

Compare every commercial office cleaning cost quote line by line against the same scope. The lowest total means little until you know what each company actually cleans on each visit.

How Lucy’s Cleaning Home prices office cleaning

We do not publish one flat commercial office cleaning cost, because a two-room office and a busy multi-room suite are not the same job. Four things set the price: the size of the space, the scope, how often we come back, and any extras such as floor care. A recurring clean costs less per visit than a one-time clean, and the first visit in an office that has not been cleaned in a while may need extra time, closer to what a full deep cleaning covers than to a routine visit.

Send us your square footage or room count, the number of restrooms and how often you want us, and we will give you a firm quote the same business day, with no visit required and no obligation. We clean offices and small business spaces outside working hours when needed, and the same team comes back each time with the same checklist. If you are also comparing prices for your home, our guide to house cleaning cost for homes covers the residential side.

Frequently asked questions

How much does commercial office cleaning cost per month?

Commercial office cleaning cost per month depends on size and frequency. ISSA prices general office cleaning at $0.09 to $0.17 per square foot, calculated from the monthly contract, so a 3,000-square-foot office works out to roughly $270 to $510 a month by that method. Small offices booked per visit often pay more per square foot.

What is the average cost to clean an office?

The average is about $253 per cleaning, with most businesses paying $161 to $402, according to Thumbtack’s 2026 data. An office under 1,000 square feet averages about $211 per visit, and 4,000 to 5,000 square feet about $834.

How much do commercial cleaners charge per hour?

Thumbtack cites $35 per hour as an example rate for commercial cleaning. Hourly pricing is common for one-time or irregular jobs, while recurring office service is usually priced per visit, per square foot or as a monthly contract.

What is the going rate per square foot for office cleaning?

ISSA’s December 2025 guide lists $0.09 to $0.17 per square foot for general office cleaning, $0.14 to $0.29 for medical and healthcare facilities, and $0.07 to $0.15 for retail spaces.

Is it cheaper to clean an office weekly or daily?

Weekly service lowers the monthly commercial office cleaning cost, but daily service usually costs less per visit, because the office never has time to build up dirt between visits. Most small offices land in between, with two or three visits a week.

What is included in a standard office cleaning?

A standard visit usually covers trash and recycling, desk and surface wiping, high-touch points, restroom cleaning and restocking, break room counters and sinks, and vacuuming or mopping floors. Carpet cleaning and hard-floor refinishing are usually priced separately.

Why do office cleaning quotes vary so much?

Commercial office cleaning cost quotes differ because companies price different scopes and use different models: per hour, per visit, per square foot or per month. Comparing them only works when every quote lists what is cleaned, how often, and what is billed as an extra.

Conclusion

Commercial office cleaning cost comes down to four numbers you can check: the size of your space, how often the crew comes, what each visit includes, and which extras you add. As benchmarks, general offices run about $0.09 to $0.17 per square foot on contract (ISSA, 2025), and a single cleaning averages about $253 (Thumbtack, 2026). Use those to sanity-check any commercial office cleaning cost you are quoted, then compare them against the same written scope.
