Commercial Cleaning Cost per Square Foot: 2026 Rates by Facility Type

Commercial cleaning for a typical office costs roughly $0.09 to $0.20 per square foot, but that figure hides a trap: some sources and bidders mean per visit, and others mean per month. The cleaning industry association ISSA puts general office janitorial at $0.09 to $0.17 per square foot. Angi's October 2026 guide puts offices at $0.10 to $0.20 per square foot, quoted per visit.

Facility type, cleaning frequency and scope move the number from there. Below are the current ranges by building type, how the three common pricing models compare, and how to turn competing bids into numbers you can actually compare.

Rates by facility type

Two widely cited sources publish commercial cleaning cost per square foot by building type. ISSA's figures come from its December 2025 pricing guide. Angi's, updated in October 2026, are per visit and come with hourly equivalents.

Facility type	ISSA, per sq ft	Angi, per sq ft per visit	Angi, per hour
General office	$0.09 to $0.17	$0.10 to $0.20	$20 to $80
Medical and healthcare	$0.14 to $0.29	$0.20 to $0.50	$35 to $80
Industrial or manufacturing	$0.08 to $0.20	$0.15 to $0.35	$50 to $90
Retail	$0.07 to $0.15	$0.05 to $0.10	$20 to $50
Schools and education	$0.07 to $0.14	$0.10 to $0.30	$30 to $80
Post-construction	Not listed	$0.15 to $0.60	$30 to $50

Medical spaces sit at the top of both lists because exam rooms, restrooms and waiting areas need disinfection protocols, more time per square foot and staff trained in them. Retail and schools sit lower because large open floors clean quickly per square foot. ISSA stresses that its figures are general guidelines rather than fixed prices.

Per visit or per month: read the fine print

A bid of "$0.12 per square foot" on a 10,000-square-foot office could mean $1,200 a month or $1,200 every night. ISSA's facility table does not say which basis it uses, but its calculation method is monthly: divide the total monthly contract cost by cleanable square footage. Its worked example is a $12,000 monthly contract on 100,000 square feet, or $0.12 per square foot. Angi's consumer guide, and many smaller providers, quote per visit instead.

Before comparing anything, convert every bid to a monthly total using the same number of visits. A useful habit is to write the monthly total, the visits per month and the cleanable square footage at the top of each bid, then compare only those three numbers.

Hourly, per square foot or flat monthly

Most commercial cleaners price one of three ways, and each fits a different kind of account.

Model	How it works	Best for	Watch out for
Hourly	You pay for time on site, per cleaner	Small offices, one or two visits a week, irregular tasks	No cap if the crew is slow; ask for estimated hours per visit
Per square foot	A rate times cleanable area, per visit or per month	Larger spaces and frequent service	Unclear whether the rate is per visit or per month; disputes over what counts as cleanable
Flat monthly	One fixed fee for an agreed scope and schedule	Ongoing contracts with stable needs	Scope creep, auto-renewal and missing exit clauses

HomeAdvisor's 2026 guide notes that cleaners tend to charge hourly for one or two cleanings a week and per square foot for three or more. In practice, most janitorial contracts end up as a flat monthly fee that was built from a per-square-foot or hourly estimate, so it pays to ask how the number was calculated.

Why published rates disagree

Put the sources side by side and the ranges do not line up neatly. Angi lists retail lower than ISSA does and medical higher; its per-visit size bands ($150 to $600 for 1,000 to 5,000 square feet) imply a wider spread again. That is not a sign that one source is wrong. Each is averaging different jobs, in different markets, at different frequencies, and some fold supplies and floor care into the rate while others price them separately.

Treat published ranges as a sanity check, not a price list. If a bid lands far outside every range in the table, ask why. A very low number often means fewer crew hours than the scope needs; a very high one may include specialty work, after-hours premiums or supplies you assumed were extra. The bid itself, built from your square footage, your schedule and your task list, is the only number that matters.

The labor math behind the rate

Labor is most of what you pay for. HomeAdvisor estimates a cleaner covers about 1,000 square feet an hour in a typical commercial space, and says neglected spaces can take two to three times longer. According to the Bureau of Labor Statistics, the median wage for janitors and building cleaners was $17.71 an hour in May 2025.

The gap between that wage and a billed rate of $20 to $80 an hour covers payroll taxes, workers' compensation and liability insurance, supplies and equipment, supervision, travel and the provider's margin. A bid far below the market rate usually means fewer hours on site than the scope requires, uninsured labor or both. Ask for proof of insurance and an estimate of crew hours per visit.

What drives the price

• Cleaning frequency. Nightly service costs more per month but less per visit, because a space cleaned every day stays easier to clean. ISSA notes that more frequent service often lowers the per-square-foot rate.
• Soil level and foot traffic. A lobby with hundreds of visitors a day takes far longer than a quiet back office.
• Restrooms and kitchens. These are the slowest rooms per square foot and often the largest line in a scope.
• Floor types and floor care. Carpet, hard floors and specialty surfaces each need different equipment and schedules.
• Scope. Trash and recycling, restocking supplies, interior glass, high dusting and disinfection all add time.
• Access and timing. After-hours, weekend or tightly scheduled work costs more, as do sites with security procedures.
• Supplies. Angi notes standard products are usually included, while eco-friendly products can add $0.02 to $0.05 per square foot.
• Local labor costs. Rates in large, expensive metros run well above national averages.

Specialty services and their rates

Periodic work is usually priced separately from routine cleaning. ISSA's per-square-foot ranges for common floor care and specialty services:

• Carpet cleaning: $0.08 to $0.25
• Hard floor scrub and recoat: $0.20 to $0.40
• Hard floor strip and refinish: $0.30 to $0.60
• Electrostatic disinfection: $0.10 to $0.30

Angi adds interior window washing at $2 to $10 per window and upholstery cleaning at $25 to $55 per item. Ask bidders to list these as separate prices with a planned frequency, so they do not quietly disappear from the routine scope.

How to compare bids

1. Write one scope and send it to every bidder: rooms, tasks, frequency and any specialty work. Our commercial cleaning scope checklist is a ready-made starting point.
2. Measure cleanable square footage, excluding storage rooms, mechanical spaces and anything cleaners will not enter.
3. Ask each bidder for a monthly total, visits per month and estimated crew hours per visit.
4. Confirm insurance, background checks and who supplies products and equipment.
5. Look for a trial period and an exit clause before you sign a long contract.

When to bring in a professional crew

A small office with a handful of desks can often be handled hourly, a few times a week. Once you are past a few thousand square feet, have public restrooms, or need floor care on a schedule, a professional crew with a written scope is easier to manage and easier to hold to account. One-off jobs are different again: Angi lists one-time commercial deep cleans at $300 to $1,500 or more per visit, which is a sensible budget for a lease handover, a move into new premises or a reset before a recurring contract starts.
