Washington is the rare state where the landscaping licence itself is an insurance mandate. Landscape work is contractor work here: you register with the Department of Labor & Industries as a specialty contractor, and registration requires a $15,000 surety bond plus liability insurance of $50,000 for property damage and $100,000/$200,000 for injury (or a $250,000 combined single limit) — on file before you may lawfully bid a job.

What Washington Actually Requires
| Requirement | Washington rule |
|---|---|
| Contractor registration | Required for landscape contracting — specialty contractor registration with L&I under RCW 18.27 |
| Surety bond | $15,000 for specialty contractors (RCW 18.27.040; general contractors $30,000) |
| Liability insurance | $50,000 property damage + $100,000/$200,000 injury, per RCW 18.27.050 — must stay in force or registration is suspended |
| Workers’ compensation | L&I state fund ONLY, from the first employee — Washington is monopolistic; private WC policies are not valid here |
The Registration Is the Insurance Mandate
Most states on this page hide their insurance requirement inside a pesticide licence. Washington puts it at the front door: RCW 18.27.050 makes the liability policy a condition of the contractor registration every landscaping business needs, and RCW 18.27.040 stacks the $15,000 bond on top. Let either lapse and the registration goes with it — advertising or bidding while unregistered is an infraction with per-violation fines, and unregistered contractors lose the right to place liens or sue for payment.
Workers’ Comp Comes Only From L&I
The half of the stack you cannot buy from a private carrier: Washington is a monopolistic workers’-compensation state. You open an account with the Department of Labor & Industries and pay the state fund directly, with premiums computed on hours worked rather than payroll — a meaningful difference for part-time-heavy landscaping crews. A “full coverage” quote from any private insurer will not include Washington workers’ comp, because it legally cannot.
The Coverages Every Landscaping Business Carries Regardless
- General liability. The rock a mower throws through a picture window, the severed irrigation main, the client’s dog out the gate your crew left open. One landscaping-specific catch: standard GL forms often exclude herbicide and pesticide claims under the pollution exclusion — if you treat lawns, ask for the endorsement by name before you buy.
- Tools & equipment (inland marine). Mowers, trimmers and blowers live on an open trailer at a job site — theft of equipment is the most-filed claim class in this trade, and it is not covered by GL or auto.
- Commercial auto for the truck AND the trailer — a personal auto policy excludes business use, and the trailer needs to be scheduled, not assumed.
- Workers’ compensation — in Washington, only from the L&I state fund, never a private carrier.

Frequently Asked Questions
Does Washington require insurance for a landscaping business?

Can a Washington landscaping 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, tools, and commercial auto.
