Moving from residential to commercial cleaning

Two businesses that share a vacuum

A residential cleaning company sells trust to a homeowner, usually on a recurring weekly or biweekly visit booked in daytime hours. A commercial cleaning company sells reliability to a facility manager or owner, usually under a written contract with a defined scope, nightly or several-times-weekly visits, and an invoice paid on terms. The mop is the same. Almost everything else changes.

Owners usually consider the move for steadier revenue. One office contract can equal several residential clients, it rarely cancels for a family vacation, and it fills evening hours when residential crews are idle. Those benefits are real, but they arrive with a longer sale, tighter margins on large accounts and a different kind of risk.

What the market looks like

Cleaning is dominated by solo operators. In 2023 there were 1,095,927 US janitorial and cleaning businesses with no paid employees, against 67,799 employer establishments, about 16.2 to 1^[1]. The average nonemployer cleaning business took in about $20,785 in receipts that year^[1]. Commercial contracts mostly go to the smaller group of employer firms, because clients want insurance, supervision and backup staff.

Those employer establishments employed 1,088,193 people in 2023, and 61.3% of them had fewer than five employees^[3]. Janitorial services employment stood at 1,084,200 in September 2026, up 1.4% on a year earlier^[4]. It is a large, slow-growing, competitive field, which is why the winners compete on reliability and communication rather than on price alone.

Side-by-side comparison

Winning the first accounts

Your first commercial clients are usually closer than you think. Residential customers own businesses, manage offices and sit on church and school boards. Small offices, medical and dental practices, real estate offices and property managers' common areas are realistic first targets; large buildings with national janitorial vendors are not.

Keep the first call short and specific. A workable script: 'We clean homes for several of your neighbors and are adding a small number of office accounts this quarter. We would like to walk through your space for fifteen minutes and send a written proposal with a fixed scope. Who handles cleaning decisions for the building?'

• Ask existing residential clients who they know, in person, not by mass email.
• Approach property managers who already trust you with move-out cleans.
• Bid two or three small accounts before any large one, to learn your real production rates.
• Collect references from the first accounts in writing, with permission to share them.

Bidding a commercial job

Commercial bids live and die on production rates: how many square feet a cleaner can complete per hour for a given type of space and task list. Rates vary widely by floor type, fixture density and specification, so build your own from timed pilot cleans rather than borrowing a number from a forum.

1. 01

   Walk the space

   Measure cleanable square feet by area type: offices, restrooms, break rooms, hallways, entry. Count restroom fixtures and note floor types.

2. 02

   Write the specification

   List each task with its frequency: nightly trash and restrooms, weekly dusting, monthly high dusting, quarterly floor care.

3. 03

   Estimate hours

   Apply your timed production rates to each area and add travel, setup and supervision time.

4. 04

   Price labor at loaded cost

   Use wages plus payroll taxes, workers' compensation, benefits and paid time off, not the hourly wage alone.

5. 05

   Add supplies, equipment and overhead

   Include consumables if you supply them, equipment wear and the office time to manage the account.

6. 06

   State exclusions and change terms

   Spell out what is not included, such as carpet extraction or window cleaning, and how added work is priced.

Example: an 8,000 square foot office cleaned five nights a week might take about 2.5 crew hours a night once restrooms and break rooms are included, or roughly 54 hours a month. At a loaded labor cost of 25 an hour, labor alone is about 1,350 a month before supplies, supervision and margin. Your own timed rates replace these illustrative numbers.

Staffing nights and supervising remotely

Commercial cleaning happens when clients are gone. BLS notes that many cleaners work evening hours and some shifts include nights, weekends or holidays^[2]. Residential cleaners who like daytime schedules may not want those shifts, so plan to recruit a separate night crew rather than stretching the day team.

Wages in the two segments are close. The median hourly wage for janitors and building cleaners was $17.71 in May 2025^[2], and for maids and housekeeping cleaners $17.07^[5]. The difference is supervision: nobody is home to notice a skipped restroom, so you need inspections, checklists signed per visit, and a supervisor who visits each site on a schedule.

• Issue keys and alarm codes per person, log them, and change codes when someone leaves.
• Use photo check-ins or a site checklist app so the client can see what was done.
• Run a monthly walkthrough with the client contact for the first six months.
• Keep a trained floater who can cover any site on short notice.

Insurance, bonding and safety

Commercial clients will ask for a certificate of insurance naming them as additional insured, and many want a janitorial bond that covers theft by employees. Contracts often include indemnity clauses; read them, and have your insurance agent read them, before you sign. Workers' compensation classifications for commercial janitorial work may differ from residential cleaning, which changes your premium.

The safety exposure is not trivial. Work fatalities among building and grounds cleaning and maintenance workers rose to 356 in 2024 from 337 in 2023^[6]. Ladders, chemicals, wet floors and lone night work all need written procedures and training before your first commercial shift.

Cash flow: the trap nobody mentions

Residential cleaning is usually paid on the day of service. Commercial accounts are invoiced, typically monthly, and paid on terms. Meanwhile your night crew is paid every week or two. A new large account can therefore drain cash for its first two months even when it is profitable on paper.

• Invoice on the first day of the month for the month ahead where the contract allows.
• Ask for ACH payment and put late-payment terms in the contract.
• Model the first 90 days of payroll against the expected payment dates before signing a large account.
• Keep a reserve or line of credit sized to at least one month of commercial payroll.

Quality control that keeps contracts

Commercial clients rarely cancel over one bad night; they cancel after a pattern they feel nobody noticed. Build a simple quality loop before the first account starts, so problems surface in your system before they surface in the client's inbox.

• A site-specific checklist for each visit, signed or photographed by the crew lead.
• A supervisor inspection at least weekly for new accounts, scored against the specification.
• A named contact at each client and a monthly two-minute check-in call.
• A same-day response rule for complaints, with the fix confirmed in writing.
• A quarterly review of each account's hours against the bid, so underpriced accounts are renegotiated at renewal rather than quietly losing money.

Example: a residential company adds offices

Example (fictional): Maplewood Home Cleaning ran four daytime teams. The owner bid three small offices referred by clients, each under 5,000 square feet, and timed every clean for the first month to build real production rates. She hired a separate two-person night crew led by an experienced commercial cleaner, and kept residential and commercial schedules, pricing and payroll reporting separate.

Within a year the company had nine office accounts. The owner turned down a large building bid that would have required doubling the night crew immediately, because one lost contract of that size would have left her with staff and no work.

Should you keep residential?

For most companies, yes. Residential work keeps day crews busy, pays faster and spreads risk across many clients. Treat commercial as a second division with its own crew, pricing and reporting, and let the numbers decide the mix over time.
