Homeowners in Washington pay an average of $1,384 per year for home insurance - 22% below the national average of $1,776. That ranks Washington as the 35th most expensive state out of 51 for homeowners insurance. Between 2018 and 2022, premiums rose by 7.9%; nonrenewal rates climbed by 48.6% over the same period.
On five-year premium growth (2018–2022), Washington ranks 20th out of 51 states. Its nonrenewal rate (0.96%) ranks 28th out of 50 - nonrenewal is an early warning indicator of insurer retreat, often tied to disaster risk.
According to the U.S. Department of the Treasury, Federal Insurance Office - "Analyses of U.S. Homeowners Insurance Markets, 2018–2022." Premium values are five-year averages across all ZIP-level observations. See methodology for how the state rank and comparison are calculated.
Across the 511 Washington ZIP codes in the U.S. Treasury FIO data, the average annual home insurance premium is $1,384. That is an average of ZIP codes, in which a ZIP of a few hundred people counts the same as one of tens of thousands. That is 22% below the national average of $1,776 per year reported by the Federal Insurance Office. Washington ranks 35th most expensive out of 51 states and territories on annual premium, with ZIP-level observations ranging from $903 in 98266 to $6,096 in 98039.
Between 2018 and 2022, average premiums rose by 7.9% in Washington, placing the state 20th nationally on five-year premium growth. The state-level loss ratio averaged 64.9%, meaning insurers retained a healthy margin after claims, typical of stable markets. Nonrenewal rates, the share of policies insurers decline to extend at expiration, averaged 0.96% across the ZIP codes that report one (94% of the state's ZIP codes; those without a published rate are smaller and higher-premium on average, so this figure is likely conservative), a climb of 48.6% over the study period (ranking 28th out of 50 states).
Within Washington, premium dispersion across ZIP codes is substantial: the most expensive ZIP (98039 in Medina) charges 575% more than the least expensive (98266 in Maple Falls), reflecting local differences in catastrophe exposure, construction costs, and claims history. The FIO dataset aggregates voluntary reporting from the 40 largest homeowners insurers covering roughly 80% of the U.S. market, so ZIP-level figures represent market averages rather than individual quotes; actual premiums vary with dwelling value, deductible, coverage limits, and insurer-specific underwriting. This page is a FIO registry extract, not a quote or a recommendation.
How to read these figures: state averages on this page are computed from U.S. Treasury Federal Insurance Office data, which the office collects directly from the largest homeowners insurers and reports at the ZIP-code level. A statewide average blends expensive coastal and wildfire-exposed markets with lower-cost inland areas, so the figure is a useful benchmark but will understate what some residents pay and overstate what others pay. The loss ratio is the share of every premium dollar that insurers returned as claims; sustained ratios near or above one signal a market under pressure, where rate increases, tighter underwriting, or nonrenewals tend to follow. Claim frequency and nonrenewal rates show how often policies result in claims and how often insurers decline to renew, both of which track local catastrophe exposure. Treat the state number as a registry average, then open the ZIP table below for the same filing year's local premium and nonrenewal extracts.
