What does commercial cleaning mean?
Commercial cleaning means cleaning performed for a commercial or institutional customer, such as an office, store, clinic, school, warehouse or apartment building’s common areas, usually by an outside company under a written agreement. The word “commercial” describes who is paying and on what terms; it does not describe a method. A commercial cleaning service is a business that sells that work.
Government statistics do not use the phrase. The Census Bureau’s 2022 NAICS manual puts most of this work under 561720, Janitorial Services, defined as establishments primarily engaged in cleaning building interiors, interiors of transportation equipment, and windows, with custodial services, housekeeping, maid services and washroom sanitation as examples. Carpet and upholstery cleaning (561740) and services such as duct cleaning, chimney cleaning and building exterior cleaning (561790) are separate codes. So in Census terms, commercial cleaning is the business-customer share of three industries.
The occupation behind it is janitor and building cleaner. O*NET, the U.S. Department of Labor’s occupational database, describes the job as keeping buildings in clean and orderly condition and performing heavy cleaning duties such as cleaning floors, shampooing rugs, washing walls and glass, and removing rubbish. Compare that with the maid and housekeeping definition on the same site, which covers light cleaning duties in private households or commercial establishments such as hotels and hospitals, and you have the practical line: commercial cleaning is heavier, scheduled, equipment-based work on premises that are empty when you do it.
A working definition for owners
Commercial cleaning is recurring, contracted cleaning of business premises, performed outside operating hours, priced monthly, and sold to a manager who is accountable for the building rather than living in it. Every part of that sentence changes how you run the company compared with house cleaning. The guide to starting a commercial cleaning business covers the setup; this page explains the service itself.
What does commercial cleaning include?
Commercial cleaning includes four kinds of work: routine janitorial service on a nightly or weekly schedule, periodic maintenance such as floor refinishing and carpet extraction, specialty services such as post-construction cleanup or disinfection, and one-time jobs such as move-out cleaning of a leased space. A contract usually bundles the first two and quotes the rest separately.
| Category | Typical tasks | Frequency | How it is sold |
|---|---|---|---|
| Routine janitorial | Trash, restrooms, vacuuming, mopping, dusting, break rooms, glass doors, restocking paper and soap | Nightly to weekly | Monthly price in the contract |
| Periodic floor and carpet care | Strip and refinish resilient floors, burnishing, carpet extraction, tile and grout scrubbing | Monthly to annually | Scheduled in the contract or quoted per job |
| Specialty | Post-construction cleanup, disinfection, high dusting, window cleaning, pressure washing, kitchen hood cleaning, biohazard | As needed | Per job, often by a specialist company |
| One-time | Move-in or move-out of a leased space, event cleanup, deep clean before an inspection | Once | Flat quote |
Two things make the scope different from residential work. First, consumables: many contracts include supplying toilet paper, paper towels, hand soap and trash liners, billed at cost plus a markup or built into the price. Second, compliance: OSHA’s walking-working surfaces rule requires employers to keep workplace floors clean, orderly and sanitary, and maintained in a dry condition to the extent feasible, which is one reason businesses buy cleaning rather than skip it. Where disinfection is in scope (clinics, gyms, daycares), the products used should be EPA-registered disinfectants applied with the label’s contact time; a disinfectant that is wiped off in ten seconds has not disinfected anything.
What is usually excluded: employees’ desks and personal items, dishes, exterior windows above the first floor, anything requiring a lift, and biohazard cleanup, unless the agreement says otherwise. Per-building checklists such as the office cleaning checklist and the medical office cleaning checklist show the task lists by building type.
Commercial cleaning vs janitorial vs custodial: what is the difference?
Commercial cleaning is the market: all cleaning sold to businesses. Janitorial service is the routine, recurring part of that market (the nightly trash, restrooms and floors). Custodial usually describes the same routine work done by a building’s own employees, as in a school custodian. The three words overlap, and companies use them loosely in their names, but that is the distinction that holds up.
| Commercial cleaning | Janitorial service | Custodial | |
|---|---|---|---|
| What it names | The whole category of cleaning for business customers | Routine recurring cleaning of a building | Routine cleaning and light upkeep by in-house staff |
| Who does it | Contractors of every size, plus specialists | Contractors (building service contractors) or in-house | Employees of the school, hospital or property |
| Typical scope | Routine plus periodic plus specialty | Routine only, with periodic work as add-ons | Routine plus minor maintenance, setups, snow |
| How it is bought | Contracts and per-job quotes | Monthly contract | Payroll |
The duties themselves are covered in the companion page on what janitorial services are. The Census lumps all three under 561720 when the work is done by a contractor; in-house custodians are counted in whatever industry their employer belongs to, which is why BLS counts 2,432,600 janitor and cleaner jobs (2025) while the Census counts 1,148,248 employees of janitorial businesses (2022).
Commercial vs residential
Residential cleaning is sold to a household, done in the daytime with the home often occupied, priced per visit by home size and paid at each visit. Commercial cleaning is sold to a manager, done when the premises are closed, priced monthly from labor hours and paid by invoice. Residential clients notice detail; commercial clients notice consistency and whether the restrooms were stocked. The cleaning business ideas guide compares the two as businesses to run.
Who buys commercial cleaning services?
Commercial cleaning is bought by whoever is responsible for a building’s condition: the office manager at a small firm, the property or facility manager for a multi-tenant building, the practice manager at a clinic, the store or franchise operator for retail, and a purchasing or facilities department for schools, governments and large companies. The bigger the buyer, the more formal the purchase.
| Buyer | What they manage | How they buy | What they ask for |
|---|---|---|---|
| Office manager or owner (small business) | One suite, 1,500 to 10,000 sq ft | Walkthrough and a one-page proposal; decides in days | Certificate of insurance, references, a price |
| Property or facility manager | Common areas and tenant spaces across one or many buildings | Competitive bids, often annual | Insurance with the owner as additional insured, bond, scope, inspection plan |
| Clinic, dental or lab manager | Exam rooms, waiting areas, restrooms | Proposal plus a review of your procedures | Bloodborne pathogen training, EPA-registered disinfectants, background checks |
| Retail, gym, restaurant operator | Floors, restrooms, front of house | Quick decision, price-sensitive | Early-morning availability, floor care capability |
| School district, government, hospital | Large campuses | Formal RFP or bid, sometimes a registration portal | Bonds, background checks, prevailing wage where it applies, references at similar scale |
Almost every buyer asks for proof of insurance before the first visit. Median premiums for cleaning businesses buying through Insureon were $59 a month for general liability, $114 for workers’ compensation and $9 for a janitorial bond (updated October 12, 2026). Where to find these buyers and how to approach them is covered in the commercial cleaning contracts guide.
Size of the market: the Census Bureau’s 2022 Economic Census counted 68,108 janitorial employer establishments with $72.6 billion in receipts, and most of that revenue is commercial. Another 1,095,927 janitorial businesses had no employees in 2023, so the market is a few large contractors, tens of thousands of small companies and about a million businesses with no employees.
How is commercial cleaning priced?
Commercial cleaning is priced four ways: a fixed monthly price (the standard for routine janitorial service), a price per square foot (common in bids for large or simple spaces), an hourly rate (for day porters and unpredictable work), and a per-job price (for periodic and specialty work). Whatever the model shown to the client, the contractor builds it from labor hours.
| Model | Used for | Strength | Risk |
|---|---|---|---|
| Fixed monthly price | Routine janitorial contracts | Predictable for both sides; easy to invoice | Scope creep if the task list is vague |
| Per square foot | Large open spaces, bid comparisons | Easy to compare bids | Ignores restroom count, condition and frequency |
| Hourly | Day porters, event cleanup, unknown scope | No estimating risk | Client questions every hour; no reward for efficiency |
| Per job | Floor refinishing, carpet extraction, post-construction | Clear deliverable | Underestimating condition |
How the monthly price is built (hypothetical numbers)
- Measure the space and count fixtures: 6,000 sq ft of office, two restrooms with five fixtures total, one break room.
- Estimate minutes per task from production rates such as those in The Official ISSA Cleaning Times (ISSA’s workloading reference, 8th edition) and your own timing: say 110 minutes a visit.
- Multiply by visits: three nights a week is about 13 visits a month, roughly 24 labor hours.
- Apply a loaded labor cost (wage plus payroll taxes and workers’ comp), say $21 an hour: about $500.
- Add supplies, travel, overhead and profit, say 60% on top of labor: a monthly price near $800.
Shown per square foot, that is $0.13 a square foot a month, which is how a facility manager will compare it. The commercial cleaning calculator runs this math, and the office cleaning prices guide gives the going ranges by building type.
Terms that go with the price
- Payment by invoice, net 15 to net 30, or at the start of the month for small accounts.
- A one-year term with 30 days’ notice, and an annual price adjustment clause.
- Consumables at cost plus a markup, or included at a fixed allowance.
- Periodic work listed with its own price and schedule, so nothing is assumed to be free.
How a commercial cleaning service actually runs
A commercial cleaning service runs on a route: each evening, cleaners (often part-time) go from building to building with keys and alarm codes, follow a per-building task list, log what they did, and move on. The owner or a supervisor inspects accounts on a schedule and handles requests from the clients during the day.
A typical evening
- 5:30 pm: a two-person crew picks up the van with the cart, backpack vacuums and the night’s supplies.
- 6:00 pm: first account, a 4,000 sq ft dental office; restrooms and exam rooms first, floors last; 50 minutes.
- 7:10 pm: second account, a 12,000 sq ft office; trash, restrooms, kitchen, vacuum traffic lanes; 2 hours.
- 9:30 pm: third account, a small gym; locker rooms, equipment wipe-down, floors; 1 hour.
- 10:45 pm: lock up, set alarms, mark the three visits complete, note the broken soap dispenser at the office for the client.
What the owner does in the daytime
- Answers client requests and schedules the extras (a carpet extraction before an open house, a deep clean after a renovation).
- Inspects two or three accounts a week and sends a short report.
- Bids new buildings, orders supplies, runs payroll and invoices.
Scheduling is the operational core of the business and the thing that gets messy first. Broombook is booking, scheduling and reminders for recurring service businesses: it holds each account’s recurring visits, assigns them to cleaners and sends reminders. It fits companies running routes of small and mid-size commercial accounts alongside residential work; it is not an enterprise facilities platform with inspection modules. See cleaning scheduling software for the details.
Is commercial cleaning the right business for you?
Commercial cleaning suits owners who want recurring monthly revenue, can work or staff evenings, and can carry payroll for a month or two before invoices are paid. It suits less well anyone who wants daytime hours, immediate payment or jobs that are different every day.
| Good fit if | Poor fit if |
|---|---|
| You want contracts that renew and revenue you can forecast | You need to be paid the day you work |
| You can hire and manage part-time evening staff | You want to do all the work yourself long term |
| You are comfortable with floor machines, chemicals and safety rules | You prefer light, detailed work in occupied spaces |
| You can fund one to two months of payroll | You are starting with no cash cushion |
Many companies do both. A residential cleaner who adds three small offices on weeknights has a commercial division, and the same scheduling, insurance and software carry over. If the answer is yes, the commercial cleaning startup guide takes you from registration to the first contract, and the office cleaning checklist shows what a routine visit covers.
