Cleaning business insurance in California: what you need

What California requires by law

Three rules apply to most cleaning businesses. First, workers’ compensation: California’s Division of Workers’ Compensation says every employer must provide workers’ comp benefits under Labor Code section 3700 once the business has one or more employees. A sole proprietor with no employees can choose to cover themselves but does not have to.

Second, janitorial registration: businesses that provide janitorial services, generally commercial cleaning, must register annually with the Labor Commissioner’s Office under the Property Service Workers Protection Act. Third, local rules: there is no statewide general business license, but Insureon notes that cities such as Los Angeles, San Diego and San Jose require a business license or business tax certificate.

General liability is not required by state law. Insureon notes it can still be required depending on the county you work in, a commercial lease or a client’s contract, which is how most cleaners end up buying it.

Janitorial registration and the insurance it requires

The Labor Commissioner defines a janitorial employer as anyone who employs at least one janitor or contracts for janitorial work by one or more covered workers. Covered workers include employees, independent contractors and franchisees who work mainly as janitors, so paying cleaners on 1099s does not get you out of registering.

Registration costs $500 a year, both for a new application and for each renewal. You must attach proof of workers’ comp: a certificate naming your exact legal entity and every location, with the Division of Labor Standards Enforcement in Oakland listed as the certificate holder. If you have no employees, you disclose the reason for your exemption on the application instead.

The penalties are steep. An unregistered janitorial employer faces a fine of $100 a day, up to $10,000, and a business that hires an unregistered janitorial contractor faces a fine of $2,000 to $10,000 for a first violation. That is why property managers and building owners check registration before signing.

Workers’ comp rates for California cleaners

California prices workers’ comp per $100 of payroll, and cleaning is not a cheap class. As reported by CPR Business Solutions from Workers’ Compensation Insurance Rating Bureau (WCIRB) figures, the advisory pure premium rate effective September 1, 2026 is $7.628 for contract janitorial work (class 9008) and $9.338 for residential cleaning (class 9096). The janitorial rate was $7.070 in 2025.

These are a starting point, not your price. The WCIRB explains that pure premium rates leave out insurers’ administrative and overhead costs, so the rates insurers actually charge are typically higher. Rates are also rising overall: Insurance Journal reported in July 2026 that the commissioner approved advisory rates averaging 10.4% higher than the year before.

As an illustration only, a residential cleaning company with $100,000 of annual payroll would start from about $9,338 in pure premium before insurer expenses and credits. Insureon reports its California cleaning customers pay an average of $259 a month for workers’ comp, reflecting mostly very small payrolls.

Penalties for cleaning without workers’ comp

California treats going uninsured as a crime. The Division of Workers’ Compensation says Labor Code section 3700.5 makes it a misdemeanor punishable by a fine of at least $10,000, up to a year in county jail or both, and the state can assess penalties of up to $100,000.

The Labor Commissioner can also issue a stop order that bars you from using employee labor until you buy coverage, plus a penalty of $1,500 per employee or twice the premium you should have paid, whichever is greater. If a worker is hurt while you are uninsured, you are responsible for all of their injury-related bills.

What clients and contracts usually add

Most of the insurance a California cleaner carries comes from clients rather than the state. Common requests include:

• General liability, for a client who slips on a wet floor or property you damage. It is usually the first policy cleaners buy.
• Additional insured status for the building owner or property manager, shown on a certificate of insurance.
• A janitorial bond, which reimburses clients if an employee steals. Insureon notes the surety will expect you to pay it back after a claim.
• Commercial auto for vehicles the business owns, or hired and non-owned auto if you or your staff drive personal cars between jobs.
• Tools and equipment coverage for vacuums, floor machines and supplies you carry from site to site.

Published figures come from marketplaces that sell to small cleaners, so treat them as a guide. Your price depends on your services, payroll, revenue, location, limits and claims history.

How to meet the requirements without overpaying

A few steps keep you compliant while holding down the bill.

• Get your workers’ comp class right. Residential cleaning (9096) and commercial janitorial (9008) carry different rates, so describe your actual mix of work accurately.
• Report payroll honestly and keep the records the Labor Commissioner requires for three years. Clean records make the year-end audit predictable.
• Renew janitorial registration on time; renewal notices go out 90 days before expiration, and lapses carry daily fines.
• Bundle general liability and property in a business owner’s policy if you have a shop or storage unit.
• Buy the bond amount and liability limits your contracts actually require, and compare several insurers, since appetite for cleaning accounts varies. A broker such as Florin can compare quotes from several insurers.
