Cleaning business insurance: coverage, requirements and costs

A cleaning business needs commercial general liability that responds to damage in the client's building, workers' compensation for a crew doing repetitive physical work, and a bond or crime cover because most clients hand you keys. The trap is that the standard liability form does not automatically pay for property in your care or the surface you are cleaning. Janitorial work sits in NAICS 561720, carpet and upholstery cleaning in 561740, and window cleaning and pressure washing in 561790.

Why cleaning businesses need business insurance

The Bureau of Labor Statistics put the 2024 recordable injury and illness rate for janitorial services at 2.5 cases per 100 full-time workers (BLS table 1, 2024). Its handbook counts about 2.4 million janitors and building cleaners in 2025, 35% of them employed in services to buildings and dwellings, and names sprains and strains from heavy lifting and repetitive motion as the usual injuries. Many of them work evenings in empty offices.

That schedule creates the other exposure: lone workers with keys, alarm codes and unrestricted access after hours. When something goes missing, the cleaner is the first suspect and the cleaning company is the defendant. Add slip-and-fall claims on wet floors, chemical damage to finishes, and the vehicle risk of crews moving between sites.

Core coverages

• General liability. The ISO form (CG 00 01) pays third-party bodily injury and property damage and your defense. Two exclusions matter for cleaners. Exclusion j(4) removes personal property in your care, custody or control, such as furniture you move. Exclusion j(5) removes damage to the particular part of real property you are working on when it arises from your operations, so a floor you strip and ruin is a different question than a visitor who slips on it. Janitorial carriers often add endorsements to buy some of that back. The Care, custody and control: why the CGL won't pay for property you hold guide explains the wording. Thimble says many janitorial policies carry the exclusion and that its own does not; read your policy, not the marketing.
• Workers' compensation. Rated by payroll in the janitorial class. NCCI classes janitorial services by contractors in 9014, which excludes window cleaning above ground level; that work goes in 9170. NCCI's Item B-1450 proposed new multistate wording for those two classes, effective July 1, 2026, and the Texas Department of Insurance declined to adopt that part, noting that "above ground level" is undefined and that employers without records would be rated in the higher class. Wording varies by state; keep payroll records by task.
• Bond or crime cover for client property. A janitorial bond is a surety bond that protects the client, not you, against employee theft or dishonesty (NEXT's New York cleaning guide says no New York law requires one), and some clients write it into the contract. It is bought separately from the insurance. Crime coverage can be endorsed to protect client property too. See employee theft coverage and fidelity bonds: what they cover and who needs one.
• Commercial auto and hired and non-owned. Crews carrying equipment between sites are on business use. If staff drive their own cars to sites, add hired and non-owned auto.
• Equipment. Floor machines, extractors and vacuums are covered under inland marine, not general liability.
• Employment practices liability. Night shifts, small teams and high turnover generate harassment, wage-and-hour and wrongful termination claims. See Employment practices liability insurance (EPLI): what it covers.

Coverage you may be required to carry

State law. Workers' compensation follows the state; see workers' comp requirements by state: who must carry it. Most states do not require a cleaning company to carry liability insurance, so the requirement comes from the client. California is the exception on registration. Janitorial employers there must register with the Labor Commissioner, pay a $500 annual fee and put employees through in-person sexual violence and harassment prevention training every two years. The registration also reaches contractors, subcontractors and franchisors who engage janitorial workers.

Government contracts. On federal work, FAR 28.307-2 sets minimums: $500,000 general liability per occurrence, $100,000 employer's liability, and auto liability of $200,000 per person and $500,000 per occurrence for bodily injury plus $20,000 for property damage. Contract schedules can set more. See insurance requirements for government contractors.

Private clients. Property managers and office owners typically want $1 million per occurrence and $2 million aggregate, additional insured status, waiver of subrogation, workers' compensation, auto, an umbrella above that, and increasingly a bond or crime cover. Run each agreement through the contract insurance requirements checker; indemnity clauses for slip-and-fall deserve attention.

Common claims and how to prevent them

• Wet-floor falls. Signs help but do not end the exposure. Hiscox's own example is a visitor who slips after a floor is waxed despite posted warnings. Barricade the area, record the time, and photograph the work.
• Surface damage. Test chemicals on a hidden spot, match the product to the finish, and keep a log of what was used where.
• Theft allegations. Run background checks, assign keys against a signed log, change alarm codes when staff leave, and carry bond or crime cover that fits the contract.
• Back and shoulder injuries. Use ergonomic tools, lift limits and rotation. Report injuries the same day; see the workers' comp claims process for employers.
• Chemical exposure. Keep safety data sheets on site, label secondary containers as OSHA's hazard communication standard requires, and ban mixing products.
• Pre-existing damage. Document with photos at the first visit, because the claim often arrives months later.

What drives the cost

• Workers' comp: payroll by class code (janitorial, window cleaning at height, carpet cleaning, other), the experience mod, and records that split the payroll. A premium audit will add uninsured subcontractors at your rates.
• General liability: receipts or payroll, the type of premises (offices, schools, medical, retail, residential), window or high-rise work, floor stripping and waxing, carpet extraction, and the share of work done by subcontractors.
• Bond and crime: the limit, the number of employees and locations, and your hiring and key-control controls.
• Auto and equipment: vehicle count, driver records and the value of machines.
• History: loss runs, turnover, training, and written procedures.

Specialized coverages to consider

• A janitorial bond or third-party crime endorsement.
• Pollution liability for chemical releases, mold remediation or biohazard cleanup, which general liability often excludes.
• High-rise window cleaning cover, which some carriers will not write on a general liability form.
• Umbrella liability to reach $2 million.
• Key coverage for rekeying after lost keys.
• Cyber exposure if you handle client data in schedules or alarm systems.

How to buy

Small residential and office cleaners can start online with carriers such as The Hartford, biBERK, NEXT, Thimble or Hiscox, all of which publish cleaning pages. Contract cleaners with building owners, hospitals or schools usually need an agent who places building service contractors, because bonding, crime cover and additional insured terms are negotiated. Have ready: payroll by class, receipts, a list of sites and types, subcontract costs, hiring and key-control procedures, sample contracts and loss runs.

Key takeaways

• Ask how your policy handles property in your care and the surface you are cleaning; the standard form excludes both in part.
• Janitorial bonds and crime cover protect the client against employee theft and are often a contract term.
• Comp classes split ordinary janitorial work from window cleaning above ground level, so keep payroll records by task.
• California requires janitorial employer registration; federal contracts carry FAR minimums.
• Document the condition of every site before the first shift.
