Most commercial janitorial contracts are priced one of three ways: per square foot, per hour, or as a flat monthly fee. ISSA, the cleaning industry association, describes the same three approaches. Behind all of them sits the same thing: labor hours, plus supplies, equipment, overhead and margin. The right model depends on how predictable your scope is. Recurring office cleaning suits square-foot or flat pricing. Variable work such as deep cleans and post-construction suits hourly or per-project pricing.
This guide is written for property managers, facility directors and building owners who sign the contract. It explains how each model is built, which buildings it fits, and how to compare proposals that use different models.
TL;DR
- The three common models are price per square foot, hourly or time-and-materials, and a fixed monthly fee. Most contracts are a blend.
- Square-foot pricing suits larger buildings and competitive bids. Hourly suits work with an unpredictable scope. Flat fees suit small, steady, recurring jobs.
- Every model reduces to labor hours. Ask any bidder for the hours behind the number.
- To compare bids fairly, give every vendor the same written scope: tasks, frequencies and square footage by zone.
- Our quotes follow a site visit, so the price reflects your building and not a generic rate card.

The three core janitorial pricing models
The models differ in what the vendor charges for, and so in who carries the risk. Under square-foot and flat pricing the vendor carries the risk of a job taking longer than expected. Under hourly pricing you carry it.
| Model | What you pay for | Who carries the risk | Best fit |
|---|---|---|---|
| Per square foot | A rate multiplied by cleanable area | Mostly the vendor | Larger facilities, competitive bids |
| Hourly / time and materials | Hours worked plus materials | Mostly the client | Variable-scope projects |
| Flat monthly fee | One fixed monthly amount for a defined scope | The vendor, as long as scope holds | Small recurring jobs |
ISSA's guidance matches this split: flat rates are easy for clients to understand and work well for small recurring jobs, square-foot rates are ideal for competitive bids and larger facilities, and hourly rates are best for variable-scope work like deep cleaning or post-construction (ISSA).
Price per square foot
Per-square-foot pricing multiplies a rate by the cleanable area of the building, then converts that to a monthly figure. ISSA gives a general U.S. range of $0.05 to $0.25 per square foot, and notes that the rate varies by location, type of cleaning and service level. Its worked example prices a 20,000-square-foot space at $0.10 per square foot, which comes to $2,000 per month (ISSA).
You can run the same math on your own building. A 2,000-square-foot office across that range works out to roughly $100 to $500 per month. A 50,000-square-foot building at $0.10 works out to $5,000 per month. These are illustrations of the arithmetic, not quotes. The real rate depends on the factors covered below.
The rate is also a useful check in reverse. Divide a proposal's monthly price by your cleanable square footage, and you get an effective rate you can set beside other bids and published ranges.
Where square-foot pricing works well
- Open-plan offices and large retail floors with consistent, repeatable tasks.
- Multi-tenant buildings where common areas are a known size.
- Bid processes where you want every vendor quoting on one common unit.
Where it misleads
Square footage says nothing about how the space is used. Ten thousand square feet of warehouse storage and ten thousand square feet of restrooms, break rooms and exam rooms are very different jobs. If a quote is a single blended rate for a mixed-use building, ask for the rate by zone.
Hourly and time-and-materials pricing
Hourly pricing charges for the crew's time, usually with materials and equipment added at cost or as a set line. ISSA lists a common hourly range of $25 to $60 and recommends hourly pricing for variable-scope projects such as deep cleaning or post-construction. It also advises setting a minimum time commitment (ISSA).
A quick example: a three-hour clean at $25 to $60 per hour comes to $75 to $180 in labor before materials and any minimum charge. Whether a given rate is a good deal depends on what the hourly figure includes. Does it cover supervision, supplies, equipment, insurance and travel? Two vendors at the same hourly rate can differ widely once those are counted.
When hourly makes sense
- Post-construction cleanouts, where debris and dust levels are only clear once you walk the job. Our guide to post-construction cleaning costs covers how those budgets are built.
- First-time deep cleans of a neglected space.
- One-off events, emergency cleanups and unusual scopes.
For project work you will often see hourly estimates converted into a fixed project price once the scope is walked. That gives you a ceiling while keeping the pricing grounded in real hours.
Flat monthly fee
A flat fee sets one monthly price for a defined list of tasks at defined frequencies. It is the easiest model to budget, because the invoice is the same every month. It works best when the scope is stable: the same rooms, the same schedule, the same standard.
Under the surface, the vendor still builds the fee from labor hours. The usual build-up is hours per visit times visits per month times loaded labor cost, then supplies, equipment, travel, overhead and profit. A flat fee is therefore only as fair as the hours assumption under it.
The Oregon Department of Administrative Services, in its janitorial costing instructions for state procurement, makes the point directly: verify that fixed-fee proposals rest on a documented labor-hour assumption, because bids with suspiciously low hours often lead to missed tasks and slipping service quality (Oregon DAS). A low flat fee is not a saving if the hours cannot cover the work.
Hybrid and per-event pricing
In practice, many buildings run on a blend. A common structure is a flat or square-foot monthly price for nightly janitorial work, plus separate pricing for periodic tasks.
Periodic services are the usual add-ons: floor stripping and waxing, carpet extraction, window cleaning and pressure washing. They are typically priced per event, per square foot or per unit, because they do not happen every night. Keeping them out of the base fee also keeps the base fee honest: you are not paying every month for work that happens twice a year.
Other hybrids you may see:
- Day porter pricing. Usually hourly or a fixed weekly fee, since the coverage window is set by the schedule. We cover this under our facility and day porter services.
- Tiered scopes. A base level, a standard level and a premium level, each with a defined task list.
- Performance-linked terms. Inspection scores or response times tied to the invoice. These need clear, measurable standards to work.

Which model fits which building
| Situation | Likely best model | Why |
|---|---|---|
| Small office, steady weekly schedule | Flat monthly fee | Simple budgeting, stable scope |
| Large office or multi-tenant building | Per square foot, by zone | Easy to bid and compare |
| Medical or clinical space | Per square foot with a defined disinfection scope | Compliance tasks raise time and price |
| Post-construction cleanout | Hourly or fixed project price after walkthrough | Scope is unclear until the site is seen |
| Tenant turn or move-out | Per unit or per project | Each space is a discrete event |
| Multi-site portfolio | Standardized rate card plus site adjustments | Consistent comparison across sites |

What moves the price under any model
Whichever model is on the page, the same drivers decide the number. ISSA identifies square footage, facility type, service frequency, labor costs, and supplies and equipment (ISSA). In plain terms:
- Size and layout. More area means more hours. Many small rooms take longer than one open floor of the same size.
- Frequency. Five nights a week costs more than three, though not in direct proportion, because setup and travel are spread over more visits.
- Facility type. ISSA notes that medical facilities require disinfection and strict hygiene compliance, and that a space's complexity and regulations affect both time and price (ISSA). Healthcare, cleanroom and food-adjacent spaces cost more per square foot than standard offices.
- Local labor costs. Wages differ by market, so the same scope costs different amounts in different metro areas.
- Service specification. Eco-friendly products, specialized equipment and after-hours access can all change the line items.
- Contract term and portfolio size. Longer terms and more sites give a vendor steadier routes and lower mobilization costs, which can support better pricing.

Why labor hours are the common denominator
A vendor who quotes you $0.10 per square foot and one who quotes $2,000 flat for the same 20,000 square feet are saying the same thing in different units. Both have estimated crew hours, multiplied by loaded labor cost, and added supplies, equipment, overhead and profit.
That is why the most useful question you can ask is: how many labor hours per week does this price assume, and for what tasks? A good bidder can answer in a few minutes. A vague answer is a warning sign, in line with the Oregon guidance above.
Contractors who track cleaning as part of project costs can also benefit from coding it consistently. A construction chart of accounts keeps hourly, per-square-foot and fixed-price cleaning invoices in one cost structure, so you can see what each model actually cost on a job.
How to compare janitorial proposals fairly
Proposals priced in different models are hard to compare by eye. The fix is to standardize the input, not the output.
- Write one scope. List tasks, frequencies, standards and square footage by zone. Precisely written scopes produce more accurate and comparable bids (Facility Management Insights).
- Ask every vendor to walk the site. Remote quotes miss the details that change hours: restroom counts, floor types, access limits.
- Request the hours assumption. Ask for weekly labor hours and the crew size behind each price.
- Convert everything to one unit. Divide each monthly price by cleanable square footage and compare the effective rates.
- Check what is excluded. Supplies, consumables, periodic tasks, holiday service and supervision are the usual gaps.
- Read the term and exit clauses. Contract length, renewal terms and termination notice affect your real cost.
On contract terms, a 2021 IFMA survey of European facility managers found terms ranging from one year or less up to six to ten years, and 62% planned to renew with their current provider. The sample is European, but it shows how common long relationships are, which is a reason to get the scope and pricing mechanism right at signing.

Red flags in a bid
- A price far below the others with no hours breakdown.
- A single rate for a mixed-use building.
- No site visit before the quote.
- Open-ended "additional charges as needed" language.
- No defined inspection or response process.
Our perspective on pricing models
We have quoted everything from single-floor offices to healthcare facilities and large post-construction cleanouts, and we have learned that no single model fits every job. Our approach is to match the model to the work.
For recurring janitorial service, we prefer a clear monthly price tied to a written scope, because it gives you a predictable budget and gives our crews a defined standard. For post-construction cleans, deep cleans and other variable work, we price after a site visit, because the real scope only shows once someone walks the space. Our process is built around that: a quote, a site visit, scheduled cleaning, and your approval.
We do not publish a rate card, because pricing depends on property size, frequency and service scope, and a generic number would not reflect your building. What we do commit to is transparency in how the number is built. You should see what is included, how often, and in which zones, so you can compare us to anyone.
We operate with local crews in every state rather than a franchise model, and we aim to respond within 24 hours. For property managers with several sites, that means one scope standard and one point of accountability across the portfolio.

FAQ
How do you charge for janitorial services?
The three standard ways are per square foot, per hour, or as a flat monthly fee. Whichever you choose, the price should rest on a written scope and a stated labor-hours assumption. Recurring work usually runs on a monthly price, and one-off projects on hourly or fixed project pricing.
How much does it cost to clean a 2,000-square-foot office?
Using ISSA's general U.S. range of $0.05 to $0.25 per square foot, the math gives roughly $100 to $500 per month (ISSA). Your actual price depends on frequency, local labor costs and what the scope includes. A site visit gives you a firm figure.
Is $50 an hour a good rate for commercial cleaning?
It sits inside ISSA's common hourly range of $25 to $60 (ISSA). Whether it is good value depends on what it covers: supervision, supplies, equipment, insurance and minimum hours. Compare the all-in cost for the same scope, not the headline rate.
Which pricing model is best for post-construction cleaning?
Hourly or a fixed project price set after a walkthrough usually fits best, because debris levels and finish details are unclear until the site is seen. ISSA also recommends hourly pricing for variable-scope work like post-construction (ISSA). Ask for a minimum time commitment and a defined completion standard.
