Commercial Cleaning Rates Per Square Foot (2026)
Commercial cleaning cost per square foot in Ontario typically falls between $0.05 and $0.50 per cleaning visit, with the exact rate driven by the type of facility, how detailed the scope is, and — counterintuitively — how large the space is. The per-square-foot figure is the unit cleaning companies use behind the scenes to price a job consistently. It is then multiplied by your square footage and your cleaning frequency to produce the flat monthly rate you sign for.
The table below shows the realistic 2026 range by facility type. These are per square foot, per cleaning visit for routine janitorial service — not per month and not for one-time deep cleans, which are priced differently (covered further down).
| Facility Type | Cost Per Sq Ft / Visit | What Drives the Rate |
|---|---|---|
| Standard office | $0.08 – $0.20 | Desk areas, restrooms, kitchenette, vacuuming — the GTA baseline |
| Retail / showroom | $0.08 – $0.20 | Open floor, glass and fitting rooms, customer-facing finish |
| Medical / dental clinic | $0.15 – $0.40+ | IPAC protocols, DIN-registered disinfectants, written logs |
| Daycare / childcare | $0.12 – $0.30 | CCEYA sanitizing, toy and surface disinfection, washrooms |
| Warehouse — routine janitorial | $0.05 – $0.12 | Large open floor area, lower touch-point density |
| Warehouse / industrial — deep clean | $0.15 – $0.35 | Degreasing, high-bay dusting, machinery, food-grade scope |
| Restaurant / commercial kitchen | $0.20 – $0.50+ | Nightly grease removal, food-safe products, compliance |
For the most common request — a standard GTA office on a regular janitorial schedule — $0.08 to $0.20 per square foot per visit covers the large majority of quotes. Smaller offices sit at the top of that range, larger ones at the bottom, and the scope of work moves you within it. Everything else in this guide explains why your specific number lands where it does.
Why Bigger Spaces Cost Less Per Square Foot
The most surprising part of per-square-foot pricing is that the rate drops as the space gets larger, even though the total bill goes up. This is economies of scale, and it is real:
- Fixed tasks spread out. Restrooms, kitchens, entrances, and emptying bins take roughly the same time whether the office is 1,000 or 10,000 sq ft. Spread across more square footage, the per-foot cost falls.
- Travel and setup are one-time per visit. Getting the crew to site, unloading equipment, and locking up afterward is a fixed cost absorbed into a larger job.
- Open area cleans faster. A big open floor plate vacuums far faster per square foot than the same area chopped into a maze of small private offices, each with its own door, corners, and bin.
In practice, a 1,000 sq ft professional office might price near $0.18 per square foot, while a 20,000 sq ft office of the same type and frequency prices at $0.07–$0.09. The big contract still costs much more in total dollars — it is just more efficient per foot. This is also why a quote expressed only as a flat monthly figure can hide whether you are getting a competitive rate: the per-square-foot basis is what makes two quotes comparable.
What the Per-Square-Foot Rate Includes
When a cleaning company quotes you a price per square foot for recurring janitorial service, that rate should cover the full routine scope — not a stripped-down version with everything billed as an extra. A standard inclusion list looks like this:
- Labour for the trained cleaning crew
- All cleaning supplies, chemicals, and consumables
- Commercial equipment (vacuums, microfibre systems, floor machines)
- Restroom cleaning, sanitizing, and restocking
- Floor care — vacuuming carpet, dust-mopping and damp-mopping hard floors
- High-touch surface disinfection (door handles, switches, shared surfaces)
- Waste and recycling collection
- WSIB coverage and general liability insurance
What is normally not in the per-square-foot routine rate — and should be quoted separately — are the periodic and one-time services:
- Floor stripping, waxing, and burnishing (hard floors)
- Carpet hot-water extraction
- Interior and exterior window washing
- Post-construction or post-renovation cleaning
- One-time deep cleans and move-in / move-out cleaning
One-time and deep cleans are usually priced by the hour, not the square foot. Most commercial cleaners in the GTA charge $30–$60 per cleaner per hour for unpredictable jobs, because the time required for a heavy reset is harder to estimate than a maintained space on a regular schedule. The per-square-foot logic is built for recurring contracts where the workload is consistent week to week.
What Moves Your Rate Within the Range
Pushes Cost Up Per Sq Ft
- Many small rooms instead of open floor
- Medical, dental, or food-prep compliance scope
- High foot traffic and customer-facing finish
- Detailed scope (glass, polishing, high dusting)
- Tight or after-hours cleaning window
- Daily service vs a few times a week
- Downtown Toronto access and parking
Pulls Cost Down Per Sq Ft
- Larger total square footage
- Open-plan layout with few partitions
- Lower cleaning frequency
- Light-maintenance scope (no deep services)
- Generous, flexible cleaning window
- Single-tenant building, easy access
- Suburban location, free parking
Per-Square-Foot Cost by Facility Type
Office and retail — the GTA baseline
Standard offices and retail spaces are the reference point for per-square-foot pricing at $0.08–$0.20 per visit. Light-maintenance scope on a larger floor sits at the low end; a small, partitioned, or detail-heavy space sits at the top. For most GTA businesses this is the band your quote will fall into.
Medical and dental — the compliance premium
Clinical environments run $0.15–$0.40+ per square foot because the work is fundamentally different: Health Canada DIN-registered intermediate-level disinfectants, proper contact times, dirty-to-clean workflow, written service logs, and staff with vulnerable sector screening. The premium over a standard office of the same size is typically 30–50%, and it is not negotiable — it reflects what the College and Public Health Ontario require.
Warehouse and industrial — it depends entirely on scope
This is where per-square-foot pricing is most misunderstood. Routine warehouse janitorial — office areas, washrooms, lunchrooms, and sweeping main aisles — is one of the cheapest categories per square foot ($0.05–$0.12) because of the vast open area. But industrial deep cleaning — degreasing, high-bay dusting, machinery, racking, or food-grade scope — jumps to $0.15–$0.35, because the work per square foot is far more intensive. Two warehouse quotes can look wildly different per foot and both be correct; the scope is what separates them.
Restaurant and commercial kitchen — the highest per-foot category
Commercial kitchens are the most expensive per square foot ($0.20–$0.50+) because of nightly grease removal, food-safe DIN-registered products, after-hours scheduling, and health-authority compliance documentation. A restaurant and an office of identical square footage are never priced in the same band.
How to Turn a Per-Square-Foot Rate Into a Monthly Budget
The arithmetic is simple once you separate the two multipliers — size and frequency:
- Cost per visit = square footage × per-square-foot rate
- Monthly cost = cost per visit × visits per month
A few worked examples for a standard office at $0.10 per square foot:
| Office Size | Cost Per Visit | 3× / Week (~13 visits/mo) | 5× / Week (~22 visits/mo) |
|---|---|---|---|
| 2,000 sq ft | $200 | ~$2,600/mo | ~$4,400/mo |
| 4,000 sq ft | $400 | ~$5,200/mo | ~$8,800/mo |
| 8,000 sq ft | $640 (rate drops to ~$0.08) | ~$8,300/mo | ~$14,100/mo |
Notice that the 8,000 sq ft example uses a lower per-foot rate ($0.08) than the smaller offices ($0.10) — that is the economies-of-scale effect in action. The frequency multiplier is just as important as size: the same office cleaned five times a week instead of three costs roughly 70% more, because you are buying nearly twice as many visits.
For a standard GTA office, take your square footage, multiply by $0.10, and multiply by your weekly visit count × 4.3 to get a ballpark monthly figure. It will not be your exact quote — only an on-site walkthrough produces that — but it tells you instantly whether a number you have been given is in the right universe.
Why Companies Quote a Flat Monthly Rate, Not Per Square Foot
If cleaning is priced per square foot internally, why does almost every recurring contract show a single flat monthly number? Because a flat rate is better for both sides:
- It is a predictable budget line. You pay the same amount every month regardless of how long a given clean actually takes.
- It shifts the risk to the cleaner. If a clean runs long, or a holiday week shortens the schedule, the company absorbs the variance — not you.
- It avoids nickel-and-diming. Per-visit invoicing invites disputes over what counted and what did not. A flat rate keeps the relationship simple.
The per-square-foot rate does not disappear — it is the engine under the hood. The right move as a buyer is to ask the company to show you the per-square-foot basis behind their monthly number. A professional will walk you through it without hesitation.
How to Compare Quotes on a Per-Square-Foot Basis
When two quotes look far apart, the per-square-foot lens almost always explains why. Before you assume the cheaper one is the better deal, check these:
Are both quotes for the same frequency?
A "cheaper" quote is often just fewer visits per week. Normalize to cost per visit first, then per square foot, before comparing.
Are both quotes for the same scope?
If one includes restroom restocking, floor care, and high-touch disinfection and the other quietly excludes them, the per-foot rates are not measuring the same work. Get the inclusion list in writing.
Is the low rate too low to be real?
A standard office quoted under about $0.05 per square foot per visit is a warning sign. At that level something is usually missing — WSIB coverage, liability insurance, proper products, or consistent staffing. The cheapest quote that cannot cover those is the most expensive mistake.
Always require a walkthrough. Any per-square-foot rate quoted by phone or email without seeing your space is a placeholder, not a price. Layout, floor type, restroom count, and access all move the real number. A professional company provides a written proposal within 24–48 hours of an on-site visit — and will show you the per-square-foot logic behind it.
Frequently Asked Questions
How much does commercial cleaning cost per square foot in Ontario?
Commercial cleaning in Ontario typically costs $0.08–$0.20 per square foot per cleaning visit for a standard office or retail space, with the rate falling as the space gets larger. Medical and food-service facilities run higher ($0.15–$0.50+ per sq ft) because of compliance and grease load, while large open warehouses fall to the low end ($0.05–$0.12 per sq ft) on routine janitorial. The per-square-foot figure is then multiplied by your cleaning frequency to produce a flat monthly rate.
Is commercial cleaning priced per square foot or per hour?
Both methods are used, but for recurring contracts the per-square-foot rate is the underlying logic and a flat monthly rate is what you actually pay. Cleaning companies estimate the square footage, the scope, and how long the job takes, then express it as a price per square foot to compare jobs consistently. One-time and deep cleans are more often quoted hourly ($30–$60 per cleaner per hour in Ontario) because the time is harder to predict.
Why do larger spaces cost less per square foot to clean?
Larger spaces benefit from economies of scale. Fixed tasks like restrooms, kitchens, entrances, and travel time are spread across more square footage, and open floor area cleans faster per square foot than a space cut up into many small rooms. A 1,000 sq ft office might price at $0.18 per square foot while a 20,000 sq ft office of the same type prices at $0.07–$0.09, even though the larger contract costs far more in total dollars.
What does the per-square-foot cleaning rate include?
A standard per-square-foot janitorial rate includes labour, all cleaning supplies and equipment, restroom servicing and restocking, floor care (vacuuming and mopping), waste removal, high-touch surface disinfection, WSIB coverage, and liability insurance. It does not normally include periodic deep services like floor stripping and waxing, carpet extraction, window washing, or post-construction cleaning, which are quoted separately.
How do I convert a per-square-foot rate into a monthly cleaning budget?
Multiply your square footage by the per-square-foot rate to get the cost per visit, then multiply by the number of visits per month. For example, a 4,000 sq ft office at $0.10 per square foot is $400 per visit; cleaned three times a week (about 13 visits a month) that is roughly $5,200 a month — in practice this is packaged as one flat monthly rate confirmed after an on-site walkthrough.
Why do cleaning companies quote a flat monthly rate instead of charging per square foot each visit?
A flat monthly rate gives you a predictable budget line and shifts the risk to the cleaning company — if a clean runs long, your price does not change. The per-square-foot rate is the tool the company uses internally to build that monthly number consistently and fairly. Asking for the per-square-foot basis behind a quote is the best way to compare two proposals on equal terms.
