Janitorial insurance for a house cleaner taking the first office account

The first office client changes more than your hours. In California it can end your exemption from a $500 janitorial registration, and everywhere it moves the limits from what you choose to what a contract says.

Say a house cleaner gets asked to do an office on Friday nights, a dental practice or a property manager's lobby, and says yes. The work is familiar. The paperwork isn't, because the person signing is a business with a vendor policy, not a homeowner asking if you're insured.

Progressive draws the line in one sentence: janitorial services may be limited to a specific building, while a cleaning business might travel to multiple job sites and customers' homes. For everything the policies pay, start at the coverage page and the general liability page. Where office and building accounts come from, and what a property manager asks a vendor for before the first invoice, is in the guide to how to get cleaning contracts. A builder's subcontract form is its own case, covered on the post-construction cleaning insurance page.

What changes when the client is a business

The owner of a house doesn't ask for a certificate on day one. A business does, and often before a key changes hands. Insureon says many commercial clients, property managers and government agencies may require general liability, janitorial bonds or other cover before signing. One of its insurance specialists puts the usual minimum for winning commercial contracts as general liability, a bond when required and a certificate of insurance. biBERK says the same about proof of insurance: many commercial clients require it before signing a contract.

The client's paperwork sets the limits, not your agent, and the contract may name the exact wording your certificate has to carry. You also work in the building after hours, often alone, with alarm codes, so a theft accusation lands on you first. That's why the bond comes up.

What office clients write into the contract

Two published vendor requirements show the range. The first is an HOA's rule for people working inside units, which is what a house cleaner meets when an owner books through a managed building. The second is a university's general rule for vendors, not a cleaning contract, but it shows how a commercial buyer writes limits.

Requirement	Evo HOA and Action Property Management (Los Angeles)	Bryant University
General liability	At least $1,000,000, including hired and non-owned auto, primary and non-contributory	$1,000,000 per occurrence, $3,000,000 annual aggregate
Auto	Hired and non-owned auto inside the liability policy	$1,000,000 combined single limit
Workers' comp	Statutory limits	Statutory, plus $1,000,000 employers' liability
Umbrella	Not asked	$1,000,000 per occurrence
Bond	Employee dishonesty bond "if reasonably available", with a special legal obligation clause for property of others	Not listed
Wording	HOA and manager as additional insured; waiver of subrogation for both	University as additional insured on general liability and umbrella

Sources: Evo HOA vendor rules, Bryant University vendor insurance policy. Bryant says these are its most common requirements and that limits may vary by contract. Evo's list is a request for changes to your policy, not lines on a form. The certificate of insurance guide walks through each one.

Additional insured, and the $3 million question

Insureon's janitorial page says many janitorial contracts require additional insured endorsements, and that they can affect what the cover costs. An endorsement names the client on your policy, so it needs your insurer's action, and a certificate alone doesn't create it.

When a contract asks for more than $2 million, Insureon's answer is an umbrella. Its example is a client that requires $3 million in general liability, met with $2 million of general liability plus a $1 million umbrella. Bryant's list above has an umbrella of its own.

California: the $500 registration that residential-only cleaners skip

In California, the step from houses to offices can change your legal paperwork, and it hinges on who your clients are. The Labor Commissioner's janitorial registration FAQ lists these as not required to register: a person or entity that only cleans residential dwellings, including private residences, condos and mobile homes. Take even one office and you no longer only clean residential dwellings.

The same page's examples of who must register include a janitorial provider that cleans commercial establishments, such as office buildings, and has no employees. It doesn't have to be a crew. A covered worker is anyone working predominantly as a janitor, whether employee, independent contractor or franchisee. The FAQ doesn't say how a mostly residential cleaner with one office client counts as "predominantly", so ask the Labor Commissioner before you sign, not after.

If you must register:

• The fee is $500, and registration runs one year and renews annually at $500.
• You need proof of workers' comp if you employ one or more employees.
• You need to give employees biennial in-person sexual violence and harassment prevention training under Labor Code section 1429.5.
• An unregistered employer faces a civil fine of $100 for each calendar day, up to $10,000.
• A client that contracts with an unregistered janitorial employer faces $2,000 to $10,000 for a first violation.

That last line explains why California office managers ask for your registration number. A business that is itself the recipient of the janitorial service is not required to register, which is the client's side of the same rule. The FAQ is the Labor Commissioner's, read here from a May 19, 2026 archive copy because the live page did not load for us. The California cleaning license page goes through the penalties, the workers' comp rule and local licenses for the state, the cleaning business license page covers the rest of the license rules, and the requirements page has the workers' comp rules.

Workers' comp when the office needs a second cleaner

A second person on the office route changes the workers' comp question. Insureon says state laws typically require it for janitorial businesses with employees, and its janitorial median is $114 a month. In California, the registration asks for proof of coverage the moment you have one employee.

The 1099 helper isn't a way around it. Insureon says that even if you mostly use subcontractors, some states or clients may still require coverage depending on how those workers are classified. California's own registration counts independent contractors as covered workers. biBERK says subcontractors are typically required to carry their own liability insurance and to get a certificate from each. State thresholds and the domestic worker rules are in the workers' comp guide.

The bond: optional by law, expected by contract

Commercial work is where the bond stops being optional in practice. NerdWallet says a commercial cleaning contract will likely require a bond. Swift Bonds says contracts above $50,000 a year typically ask for a bond of $10,000 to $25,000, and that hotels and hospitals often want $25,000. Those are Swift's descriptions of client habits, not a rule. Insureon's janitorial median is $10 a month, or $120 a year.

Read the clause before you buy. Evo's request is for a clause covering property of others stolen by your employees, so ask the seller whether its form carries that wording. Prices, amounts, application steps and the conviction and repayment fine print are on the janitorial bond page.

What janitorial cover costs: $9 a month more for liability

Insureon publishes a separate janitorial page, with medians for the janitorial businesses that buy through it. Beside the house cleaning medians:

Policy (monthly)	Janitorial median	House cleaning median	Janitorial, annual
General liability	$60	$51	$725
Workers' comp	$114	$100	$1,362
Janitorial bond	$10	$9	$120
Commercial auto	$234	$268	$2,810
Business owner's policy	$77	$79	$919
Commercial umbrella	$87	$72	$1,040

Sources: Insureon janitorial costs (updated September 3, 2026) and house cleaning costs (September 1, 2026). Insureon says most of its customers in both groups have fewer than five employees and $50,000 to $200,000 or more in revenue, and that the sample general liability policy carries $1 million per occurrence and $2 million aggregate. The gap in general liability is $9 a month. The umbrella is $15 a month higher for janitorial businesses, and Insureon says it is the policy that meets a client's demand for higher limits.

Insureon says janitors who wax floors, do industrial cleaning, pressure wash or handle hazardous materials may pay higher premiums than businesses doing basic office cleaning. Hiscox's own claim example is a fall after waxing where someone slips and breaks their wrist although warning signs were up. If floor work is part of the bid, put it on the application.

Professional liability is the line to ask about for mistakes in the work itself. ERGO NEXT's janitorial page gives permanent marks on a carpet from the wrong stain remover as its professional liability example.

Questions to answer before you bid

• What limits and endorsements does the contract name, and can my insurer issue them before the first night?
• Is the client asking for a bond, a dishonesty bond with a special clause or crime coverage? See the bond page.
• In California, am I registered, or do I qualify for the residential-only exemption after this client?
• Do I employ anyone, or use 1099 helpers, and is workers' comp in place for them?
• Does my general liability quote include hired and non-owned auto if I drive my own car to the site?
