Commercial cleaning is one of the few service businesses you can start lean, run nights and weekends around a day job, and grow into recurring monthly revenue without a degree or a franchise fee. The U.S. janitorial services market was worth roughly $112 billion in 2026 and has grown about 2.7% a year over the prior five years (IBISWorld). That growth is steady, not explosive — which is what makes it dependable. Offices, medical buildings, schools, and warehouses need cleaning whether the economy is up or down.
This guide walks through how to actually start a commercial cleaning business — the B2B, after-hours, contract side of the trade — without inventing numbers. If you’re weighing residential maid service instead, start with our broader guide to starting a cleaning business.
Commercial vs. residential: why janitorial is a different game
- Recurring contracts, not one-off jobs. Commercial runs on signed contracts — monthly billing for nightly or weekly service. You’re selling reliability over months.
- After-hours work. Most offices want cleaners in after staff leave — an advantage if starting around a day job, but it shapes hiring.
- Bidding by square footage. Priced on cleanable square footage and time to clean, not a flat “three-bedroom” rate.
- Insurance and bonding usually mandatory. Most clients won’t award a contract unless you’re insured and bonded (Insureon).
- W-2 crews vs. subcontractors. More control vs. less overhead — with real legal risk if you misclassify.
Step-by-step: how to start a commercial cleaning business
1. Register the business and pick a structure
Most owners form an LLC. State filing fees run about $40–$500 (Jobber). Your EIN from the IRS is free. Keep business and personal money completely separate from day one.
2. Get licensed, insured, and bonded
Licensing varies by state and city (verify locally). The three things commercial clients check:
- General liability insurance: often around $30–$60/month for a small operation (Aspire).
- Workers’ compensation: roughly $800–$3,000/year for a small team, usually required once you have employees (Aspire).
- Janitorial (surety) bond: averages about $11/month ($126/year); commercial clients often want a $25,000–$50,000 bond (Insureon).
3. Buy starter equipment and supplies
Plan on roughly $2,000–$5,000 in commercial equipment (Housecall Pro), plus consumables. All in, many commercial startups land between $20,000 and $50,000 if buying vehicles and heavier equipment up front — but you can start far leaner and reinvest as you sign accounts (Aspire).
4. Learn to price and bid a commercial job
Common benchmarks: $0.07–$0.20 per square foot for standard recurring office cleaning, or $30–$75/hour hourly, with productivity near 3,000–4,000 cleanable sq ft/hour (Jobber; The Janitorial Store). Figure cleanable square footage, estimate time, multiply by your fully loaded hourly price. Labor runs 50–60% of job cost, supplies 3–5%, overhead 20–30% before profit (Jobber). Run your rates through our true hourly rate calculator, our commercial cleaning bid calculator, and markup vs. margin calculator. Always walk the building before you bid (ISSA).
5. Land your first contracts
- Direct outreach to the property or facilities manager at offices, medical, retail, HOAs, and private schools; book a walk-through (Jobber).
- Referral relationships with commercial real-estate agents and property managers — one can hand you several buildings (Insureon).
- RFPs and open bids — schools and agencies post contracts on SAM.gov and local portals (Janitorial Manager).
- Local networking — chambers of commerce and business groups.
The recurring-revenue advantage
The reason operators favor commercial: contracts compound. A single office billed every month is worth far more than the same dollar amount in scattered one-time jobs — because you keep it. A handful of nightly accounts gives you a predictable monthly base before any new selling, which lets you hire, buy better equipment, step out of cleaning yourself, and eventually sell the business — buyers pay for recurring contracts.
Tools to run a commercial cleaning business
- Scheduling, work orders, invoicing. Jobber and Service Fusion handle scheduling, client records, invoicing, and recurring billing across accounts.
- Janitorial-specific operations. Swept focuses on crew communication, time/attendance, checklists, and supply tracking; Janitorial Manager targets larger operations.
- Bookkeeping. Keep books clean with QuickBooks.

Common mistakes to avoid
- Bidding without walking the building. You’ll underprice and lose money or quit the contract.
- Forgetting overhead and profit. Carry 20–30% overhead plus profit or a busy month still loses money (Jobber).
- Skipping bonding. It’s cheap and many clients won’t sign without it (Insureon).
- Misclassifying workers. Calling W-2 cleaners “subcontractors” is a real legal risk.
- Competing only on price. The lowest bid attracts clients who leave for the next lowest bid.
Frequently asked questions
How much does it cost to start a commercial cleaning business?
A true commercial operation buying heavier equipment and a vehicle can run roughly $20,000–$50,000 (Aspire); first-year licensing, insurance, and bonding typically land around $2,000–$5,000 on their own (Jobber). You can start leaner and reinvest as contracts come in.
How do I get commercial cleaning contracts?
Combine direct outreach to property/facilities managers, referrals from commercial real-estate agents, public RFPs on SAM.gov and local portals, and networking (Jobber; Janitorial Manager). Always offer a walk-through and follow up.
Do I need to be bonded?
Not legally, but most commercial clients require it before awarding a contract — it protects against employee theft and costs about $11/month average (Insureon).
Commercial vs. residential — which is more profitable?
Commercial’s edge is recurring revenue from signed monthly contracts, making it easier to scale and sell. Residential can carry higher per-hour rates on premium deep cleans but is more one-off. Either way, profit comes down to disciplined bidding and controlling labor (50–60%) and overhead (20–30%) (Jobber).
How do you bid a commercial cleaning job?
Walk the building, then calculate cleanable square footage, time to clean, and your fully loaded hourly price. Many use $0.07–$0.20/sq ft or 3,000–4,000 sq ft/hour as a reference, then add supplies, overhead, and profit before quoting a flat monthly rate (Jobber; The Janitorial Store).
The bottom line
A commercial cleaning business rewards discipline over flash. The startup math is forgiving; the pricing math is unforgiving if you bid blind. Register properly, get insured and bonded, walk every building before you quote, and price for profit. Land a few reliable monthly accounts and you’ve built something that pays you whether or not you sold anything new this month.
