Washington splits your insurance shopping in two: the state sells one coverage, the market sells the rest. Workers’ compensation comes only from the Department of Labor & Industries — Washington is a monopolistic state, so a private WC policy is not valid here — and coverage is required from the first employee, with premiums computed on hours worked rather than payroll. General liability, the janitorial bond and commercial auto still come from private carriers.

What Washington Actually Requires
| Requirement | Washington rule |
|---|---|
| Workers’ compensation | L&I state fund ONLY, from the first employee — private WC policies are not valid in Washington; premiums assessed on hours worked |
| State cleaning licence | No cleaning-specific licence — but every WA business files the state Business License Application with the Department of Revenue |
| Janitorial bond | Not state-mandated — Seattle-market office and property contracts routinely require one |
Two Sellers: L&I for Workers’ Comp, the Market for Everything Else
A “full coverage” quote from any private carrier will simply not include workers’ comp in Washington — you open an L&I account and pay the state fund directly, at rates set per hour worked for your risk class. For a cleaning business the hours-based premium cuts both ways: part-time-heavy crews pay on the hours they actually work, but every scheduled hour is premium-bearing from hire one.
An out-of-state cleaning company crossing into Washington with its home-state WC policy is uncovered for Washington work — the L&I account is not optional for crews working across the state line.
What Skipping It Actually Costs in Washington
Because Washington’s coverage is a state fund, going without it here isn’t “uninsured” — it’s unregistered, and L&I treats it as premium evasion. An employer operating without an account faces penalties that start at roughly $1,300 or twice the premiums owed, whichever is greater (the floor is inflation-adjusted upward each cycle), on top of the back-premiums themselves.
The sharper provision waits for an injury. Under RCW 51.48.010, when a worker is hurt before the employer secured coverage, the employer is liable for a penalty of not less than 50% and up to 100% of the entire cost of that injury — and cleaning-trade injuries, with their surgeries and time-loss payments, run into six figures without difficulty. The worker is still covered; the state fund pays and then collects from the business. In a first-employee, hours-rated system, the L&I account belongs on the same day-one checklist as the business licence.
The Coverages Every Cleaning Business Carries Regardless
- General liability. The scratched hardwood, the bleach spot on a client’s carpet, the wet-floor slip. One cleaning-specific catch: many policies exclude damage to property in your care, custody or control — which can mean the very surface you were hired to clean. Ask the question before you buy, not at claim time.
- Janitorial (fidelity) bond. Covers employee theft from client premises — the coverage commercial clients ask for by name before handing over keys and alarm codes. No state requires it; nearly every office contract does.
- Commercial auto for the crew vehicle — a personal policy excludes business use.
- Workers’ compensation — in Washington, only from the L&I state fund, never a private carrier.

Frequently Asked Questions
Can a Washington cleaning business buy workers’ comp from a private insurer?
No. Washington is a monopolistic workers’-compensation state: coverage comes only from the Department of Labor & Industries state fund, required from the first employee, with premiums computed on hours worked. Private carriers sell the rest of the stack — general liability, bond, auto and tools.
Does Washington require a licence for a cleaning business?
There is no cleaning-specific state licence, but every Washington business registers via the state Business License Application with the Department of Revenue, and L&I coverage is mandatory once you employ anyone.
