Homeowners insurance in Washington

The home insurance market in Washington

Washingtonians paid $3.85 billion in homeowners premiums in 2025, according to NAIC market share data. These are the 10 largest insurance groups by 2025 direct premiums written:

Five groups each write at least 10% of the market, and the top 10 together hold about 86%. Liberty Mutual's number includes the old Safeco book; Liberty Mutual, which bought Safeco in 2008, retired that brand on April 25, 2026 and now sells those policies under its own name through the same independent agents. Two Northwest mutuals round out the list: Seattle's PEMCO, which works only in the Pacific Northwest, and Mutual of Enumclaw.

What drives home insurance costs in Washington

NAIC's average HO-3 premium in Washington was $1,232 in 2023, against $1,737 nationally, the 15th lowest of 51 by our ranking of NAIC's table. That average hides sharp local increases: premiums rose about 70% in Franklin County and just over 50% in Benton County from 2018 to 2024, according to Washington Center for Real Estate Research figures reported by the Tri-Cities Area Journal of Business in June 2026.

Wildfire is reshaping the east-side market. The Office of the Insurance Commissioner (OIC) says the number of homeowners nonrenewed or canceled by their insurer has doubled since 2021, largely because of wildfire risk. FEMA's major disaster declaration for the August 2023 wildfires (DR-4759) covered Spokane and Whitman counties, and wildfires on the Yakama and Colville reservations brought further declarations in 2024. West of the Cascades the recurring loss is water: storms, flooding and landslides from Dec. 5 to 19, 2025 led to a declaration (DR-4906) with individual assistance in King, Pierce, Snohomish, Skagit, Whatcom and other counties.

Earthquake is the catastrophe standard homeowners policies leave out. The state's Geological Survey says Washington has one of the highest risks of large, damaging earthquakes in the country. The last Cascadia subduction zone earthquake, about magnitude 9, struck on Jan. 26, 1700, and USGS forecasts cited by the Survey put the chance of a magnitude 9 megathrust earthquake affecting Puget Sound at 15% within 50 years.

Deductibles and coverage rules to know

Washington has no hurricane deductible rules and is not on the Insurance Information Institute's list of hurricane-deductible states; any wind or hail deductible is your insurer's choice.

Earthquake coverage is an endorsement or separate policy, and the OIC says its deductibles usually run 10% to 25% of the building limit, sometimes with separate deductibles for contents and detached structures. Say your dwelling limit is $600,000 with a 15% earthquake deductible: the first $90,000 of quake damage is yours. Insurers may require bolting, wall bracing or water heater strapping first. Run your numbers in the hurricane and percentage deductible calculator and read earthquake insurance explained.

Volcanic eruption is partly covered: the OIC says most homeowners policies cover ash, dust and lava damage and ash cleanup, but not the shaking from an eruption, and it treats mudflows as a flood insurance matter. See volcanic eruption coverage: ash, lava and what your policy pays.

On credit, Washington insurers may not cancel or nonrenew a homeowners policy based in whole or in part on credit history (RCW 48.18.545). The Commissioner's broader ban on credit in pricing was struck down in 2022 and repealed in 2023. See insurance scores: how credit affects home insurance.

Flood and other gaps

FEMA counted 28,899 NFIP policies in force in Washington as of Sept. 30, 2026. King County had the most (6,835), followed by Skagit (3,007), Pierce, Whatcom and Snohomish. The December 2025 storms hit several of those same counties, a reminder that a homeowners policy does not pay for rising water. See NFIP flood insurance explained and the 30-day flood insurance waiting period.

If you can't find coverage

The Washington FAIR Plan insures property that meets reasonable underwriting standards anywhere in the state, through any licensed agent. It is bare-bones: a standard fire policy, with windstorm, hail, smoke, volcanic action and other extended-coverage perils and vandalism as options, settled at actual cash value only. It writes no theft, liability or fair rental value coverage, so liability has to come from somewhere else, and it caps coverage at $1.5 million per location. The plan says neighborhood location alone is not a reason to decline. The other route is surplus lines home insurance when standard carriers say no. See FAIR plans explained: the insurer of last resort for homes.

Washington's notice rules (RCW 48.18.290 and 48.18.2901, for policies issued or renewed since July 1, 2025):

• Nonrenewal or cancellation: at least 60 days' written notice, with the insurer's actual reason; 10 days for nonpayment.
• Renewal terms: the renewal offer, sent at least 20 days before expiration, must show any rate increase and explain contract changes; if it does not, the insurer must renew on the expiring rates and terms.

Claims rules and deadlines

Washington's claim rules change on Oct. 18, 2026 (WSR 26-17-089). Until then, an insurer must acknowledge a claim within 10 working days and accept or deny it within 15 working days after receiving fully completed proofs of loss, with written updates if it needs more time. From Oct. 18, the clock runs from your notice of claim, not the proof of loss: the insurer must acknowledge within 10 business days, finish its investigation and accept or deny within 30 calendar days, and if it needs longer, explain every reason in writing and update you every 30 days, including what it is still waiting for. On request it must disclose the date and source of the pricing and labor data behind its estimate.

Washington's Insurance Fair Conduct Act (RCW 48.30.015) lets a court triple your actual damages and award attorney fees if an insurer unreasonably denies a claim or violates key claim rules, but you must send 20 days' written notice to the insurer and the OIC before suing. A property policy cannot shorten the time to sue below one year from the date of loss (RCW 48.18.200), so check your policy's clause. Washington has no claim mediation program; amount-of-loss disputes go to the appraisal clause. See bad faith claim handling: what it means and what it doesn't.

Discounts and mitigation programs

Washington has no state grant for home hardening. IBHS Wildfire Prepared Home designations are available in the state, and the OIC calls the standard the industry's leading home-hardening benchmark, but any discount is the insurer's choice. Commissioner Patty Kuderer's 2026 bills to fund Strengthen Washington Homes grants and to require insurers to disclose and explain wildfire risk scores both passed the Senate (37-11 and 48-1) and died in the House Consumer Protection and Business Committee; both are priorities again for 2027. See home hardening for wildfire and insurance discounts and wildfire risk scores and how insurers use them.
