Homeowners Insurance in Washington State: How a Policy Works and What It Leaves Out
$1,151 a year. That was the average premium for a standard HO-3 homeowners policy in Washington in 2022, against $1,569 for the U.S. as a whole, according to NAIC data published by the Insurance Information Institute (Triple-I). Washington paid about 73% of the national average and ranked 37th in Triple-I's state table, where 1 is the most expensive. 2022 is the newest state figure I can verify; NAIC has since released a 2023 report, but I couldn't confirm its Washington premium, so I'm not quoting one.
Cheaper than average isn't the whole story. Washington's average rose 70% from 2013 to 2022, against 43% nationally. And the price says nothing about what the policy pays for. That's in the contract, which has more holes than most people expect: no earthquake, no flood, no sewer backup, no wear and tear, and a settlement formula that can shrink a claim if your dwelling limit is too low.

| 2022 | $1,151 | $1,569 |
Two things in that chart are worth a closer look. Washington closed part of the gap: it went from 62% of the U.S. average in 2013 to 73% in 2022. And the last year jumped. From 2021 to 2022 the Washington average rose 15% ($1,001 to $1,151), compared with 11% nationally. One caution: there's a big step from 2014 to 2015 that may reflect changes in the data rather than prices, so I wouldn't read much into that single year.
The OIC's explanation is plain: Insurance premiums go up when the costs of repairing or replacing homes go up. Inflation can also affect premiums.
(OIC).
Is homeowners insurance required in Washington state?
Not by state law. I'm not aware of any Washington statute that requires it, and the OIC treats it as a choice once there's no loan: If you don't have a mortgage, it's still a good idea to protect your investment and buy homeowner insurance
(OIC).
Your lender is a different matter. Per the OIC, If you have a home and a mortgage, your lender will require you to have homeowner insurance.
Let it lapse and the lender can buy lender-placed (force-placed) insurance on the house. Per the OIC, it protects your lender, not you,
usually costs much more than your own policy, and gets added to your loan payment (OIC). Avoid it by keeping your own policy, listing the lender as lien holder and sending the lender your declarations page.
Flood is the one place where federal law steps in. Under 42 U.S.C. 4012a(b), a regulated lender can't make, increase, extend or renew a loan on a building in a FEMA special flood hazard area (where NFIP coverage is available) unless the building is covered by flood insurance for the term of the loan. The amount has to be at least the outstanding principal balance or the maximum NFIP coverage for that type of property, whichever is less.
| Coverage | Washington law | Mortgage lender | No mortgage |
|---|---|---|---|
| Homeowners policy | Not required | Required | Your choice |
| Flood insurance | Not required | Required in a special flood hazard area (federal law); may be required elsewhere | Your choice |
| Earthquake coverage | Not required | Varies by lender | Your choice |
| Lender-placed insurance | n/a | Bought by the lender if your coverage lapses; protects the lender | n/a |

Which kind of policy most Washington owners have
"Homeowners insurance" is really a family of standard forms, numbered HO-1 through HO-8. NAIC's latest report counts coverage in house-years (one home insured for one year). In Washington in 2023, nearly half of all residential policies, renters and condos included, were the HO-3.
Source: NAIC, Dwelling Fire, Homeowners Owner-Occupied, and Homeowners Tenant and Condominium/Cooperative Unit Owners Insurance: Data for 2023 (July 2026); shares calculated
Show the numbers
| Form | Share of house-years |
|---|---|
| HO-3 | 48.7% |
| HO-4 (renters) | 27.9% |
| HO-5 | 12.7% |
| HO-2 | 5.1% |
| HO-6 (condo unit) | 4.9% |
| Dwelling fire | 0.5% |
| HO-1 and HO-8 | 0.1% |
The HO-3 (the ISO "special form") is the standard owner-occupied house policy. It's 48.7% of Washington house-years, a bit below its 55.1% share nationally. The HO-5 is the other big owner form here at 12.7%. HO-4 is renters insurance and HO-6 is the condo unit owner's policy.
Insurers write their own wording, but much of it follows the standard form, so my examples quote the ISO HO-3 sample form (2000 edition) hosted by Triple-I. Your own policy is what counts.
If you own a condo, the setup is different: the association's master policy and your unit policy work side by side, and what your unit policy has to cover depends on the association's governing documents (OIC guide). Ask for those documents before you pick limits.
The six coverages in a homeowners policy
The OIC calls a homeowners policy a "package" policy: it bundles coverage for the house, other structures, your belongings, extra living costs, medical payments for guests, and lawsuits against you. Section I of the policy covers property; Section II covers liability and guest medical payments. The letters A to F come from the ISO form. Your declarations page shows a dollar limit for each.
| Coverage | What it pays for | Typical amount (OIC) | On a $500,000 dwelling limit |
|---|---|---|---|
| A. Dwelling | Repairing or rebuilding the house and attached structures, such as an attached garage or deck | Set from the home's estimated rebuilding cost | $500,000 |
| B. Other structures | Detached garage, fence, workshop, gazebo; usually not buildings you rent out or use for business | Typically 10% of dwelling | $50,000 |
| C. Personal property | Your belongings, with lower sub-limits for items such as jewelry, firearms, silver and collections | Usually 50% to 70% of dwelling | $250,000 to $350,000 |
| D. Loss of use | Extra living costs (housing, extra mileage, extra food) while the home is unlivable after a covered loss | Most policies: 20% of dwelling | $100,000 |
| E. Personal liability | Injury or property damage to others when you're legally liable, at home or away | Most policies: at least $100,000 | $100,000 or more |
| F. Medical payments | Medical bills of guests hurt on your property, regardless of fault | Most policies: at least $1,000 | $1,000 or more |
Source: OIC, A consumer's guide to homeowner insurance (rev. 3/26); letters A to F from the ISO HO-3 form. Right-hand column is a hypothetical calculation. These are typical policy amounts, not legal minimums: Washington law doesn't set any.
A few things in that table catch people out.
Loss of use has two limits. The OIC notes it typically has a dollar limit and a time limit. It pays the extra cost of living somewhere else, not your mortgage payment or your usual utility bills. After a big fire or a long rebuild, both limits matter; the wildfire post walks through that.
Contents have sub-limits. On the standard ISO form, theft of jewelry, watches and furs is capped at $1,500, theft of firearms at $2,500, cash at $200 and business property at home at $2,500. If you own something worth more than that, it needs to be scheduled or endorsed separately. Contents are also covered away from home, but the OIC says most policies cap that at 10% of the personal property limit.
Liability follows you. Coverage E isn't limited to your lot, and $100,000 is a floor in most policies, not a recommendation. The OIC lists umbrella liability among the optional coverages.
What a Washington homeowners policy leaves out
The HO-3 covers the house and other structures on an "open perils" basis: it insures against risk of direct physical loss
unless the policy excludes it. (Your belongings are covered only for a named list of perils.) That makes the exclusions list the most important page in the contract. The OIC says it in one line: Homeowner insurance usually doesn't cover floods and earthquakes
(OIC). Those are the two big gaps in Washington, but not the only ones.
| Excluded on the standard form | The fine print | How people fill the gap |
|---|---|---|
| Earthquake and other earth movement | Includes landslide, mudflow, sinkholes and ground sinking or shifting. Fire or explosion that follows a quake is covered. | Earthquake endorsement, separate policy or difference in conditions coverage; separate deductible, usually 10% to 20% |
| Flood and surface water | Includes waves, tidal water and overflowing bodies of water | Separate flood policy (NFIP or private) or difference in conditions coverage |
| Sewer or drain backup, sump overflow | Water that backs up through sewers or drains | Sewer backup or sump pump endorsement |
| Groundwater seepage | Water below the surface seeping through foundations, walls or floors | Not on the OIC's list of add-ons; ask what a flood policy says |
| Wear and tear, rot, rust, settling, pests | Also mechanical breakdown, latent defects, cracking from settling, birds, vermin and insects | Maintenance, not insurance |
| Mold, fungus, wet rot | Except hidden mold from an accidental leak in plumbing, heating, A/C, sprinklers or an appliance | Fix leaks fast; the exception is narrow |
| Code upgrades (ordinance or law) | Limited additional coverage, up to 10% of the dwelling limit | Ask about a higher ordinance-or-law limit |
| Vandalism on a vacant home | Not covered if the home was vacant more than 60 days in a row before the loss | Read the vacancy wording before a long absence |
| Frozen pipes | Covered only if you kept the heat on or shut off and drained the water | Heat or drain the plumbing |
Source: ISO Homeowners 3 Special Form HO 00 03 (2000 edition), sample via Triple-I; OIC homeowner insurance guide (optional coverages, earthquake deductible); OIC (difference in conditions coverage). Wording varies by policy.
Earthquake coverage is optional, not every company offers it, and some want the house retrofitted or the water heater strapped first. The deductible is a percentage of the coverage amount, so on $500,000 of earthquake coverage a 10% deductible is $50,000 before the policy pays a dollar. The Washington earthquake insurance post has the USGS odds and the deductible math.
Flood is the other gap. FEMA's own line: Most homeowners and renters insurance does not cover flood damage.
NFIP policies cover up to $250,000 on the building and $100,000 on contents, and coverage usually starts 30 days after you buy it (FloodSmart). That waiting period is why buying flood coverage once the river forecast turns ugly is usually too late. The exceptions are narrow; one is buying it as part of making, increasing, extending or renewing a mortgage. Our Washington flood insurance page explains how it fits next to a home policy.
Wildfire is different: fire is a covered peril on the standard form. My read: after a wildfire, the hard questions tend to be about limits and living expenses, not exclusions.
Replacement cost, actual cash value and the 80% rule
- Replacement cost pays to repair or replace at today's prices, without taking off depreciation. The OIC says it's standard on most homeowners policies for the house.
- Actual cash value (ACV) pays replacement cost minus depreciation. The OIC's example: a TV bought for $1,000 five years ago and damaged in a fire gets paid at what it's worth today.
Contents are where people get surprised. The base ISO form settles personal property at ACV; replacement cost for contents is an add-on, and per the OIC guide it typically pays the depreciated value first and the rest after you replace the item and send receipts.
The house has its own catch. Under the ISO HO-3 loss settlement clause, you get full replacement cost only if your dwelling limit is at least 80% of the full cost to rebuild at the time of the loss. Below that, the insurer pays the greater of the ACV of the damaged part, or a proportion of the repair cost after the deductible: your limit divided by 80% of the rebuild cost.
On the ISO form, the insurer also pays no more than ACV until the repair is actually done (small losses excepted), and if you take the ACV payment first, you have 180 days from the loss to tell the insurer you'll claim the rest.
Your rebuild cost isn't the sale price or the county assessment. The OIC guide warns the insurance amount may not match the local government's assessed value
and that rebuilding can cost more than market value. Most policies adjust the dwelling limit at renewal,; still, tell the insurer about a remodel or addition, because the OIC says it can affect how much coverage you need. Some policies offer an extended replacement cost endorsement that pays above the limit, which matters most on a total loss.
What sets your premium, and your right to know why it went up
The OIC doesn't set home insurance rates. Insurers file rate changes, and the OIC reviews and either approves or denies
them; state law requires rates that are reasonable and not excessive, inadequate or unfairly discriminatory. The filings are public through SERFF Filing Access (OIC guide).
The OIC lists the main rating factors as territory, construction (wood frame carries more fire risk, masonry more earthquake risk), the amount of insurance, credit history (insurance score) and claims history. Underwriting also looks at the roof, the age of the home's systems, fire protection and any gap in coverage. Even filing a claim can count: per the OIC, If you file a claim, your insurer may decide to stop covering you or increase the cost of your coverage
(OIC).
When the renewal comes in higher, Washington gives you a right to an explanation under chapter 284-30A WAC. It applies at renewal for home, condo, renters, manufactured home and auto policies, and the dates are staged:
| Starting | What the insurer must do at renewal |
|---|---|
| June 1, 2024 | Give a reasonable explanation of any premium increase if you ask in writing |
| Nov. 1, 2026 | Print a "Did my premium go up?" notice on renewal notices, renewal emails and bills, with an email and mailing address for your request |
| March 1, 2027 | On request, explain the increase and give up to three primary factors behind it |
| Jan. 1, 2029 | Send a notice automatically, at least 20 days before renewal, when the premium rises 10% or more |
Source: WAC 284-30A-020, -040 and -050 (as amended by WSR 26-15-007, effective Aug. 2, 2026); OIC, insurers must explain premium increases.
Once the insurer receives a written request, it has 20 calendar days to answer. My read: use it. It costs nothing, and the answer tells you whether the increase is something you can change. The OIC also suggests asking about multi-policy, long-time customer and protective device discounts, and weighing a higher deductible.
Cancellation, nonrenewal and credit: the rules in Washington law
Source: RCW 48.18.290; RCW 48.18.2901; RCW 48.18.200.
Since July 1, 2025, a Washington insurer has to give at least 60 days' written notice before cancelling or not renewing a homeowners policy, and the notice has to state the insurer's actual reason (RCW 48.18.290, RCW 48.18.2901). It used to be 45 days; SSB 5798 changed that for policies issued or renewed on or after July 1, 2025. Nonpayment is the exception, with 10 days' notice. Your mortgage lender gets a copy of a cancellation notice too.
There's one wrinkle on nonrenewal. Instead of a nonrenewal notice, an insurer can send a written renewal offer with the premium at least 20 days before the policy expires. If you don't pay, the policy ends. Open renewal mail; don't assume it's a routine bill.
Credit gets its own statute, RCW 48.18.545. An insurer shall not cancel or nonrenew personal insurance based in whole or in part on a consumer's credit history or insurance score.
Credit alone can't be the reason to deny you coverage, and having no credit history or medical collection accounts can't be a reason to deny you. Credit can still affect your price; if it does, the insurer has to tell you the main reasons in writing.
If you think a notice or a decision breaks these rules, the OIC's consumer advocates take calls at 800-562-6900, weekdays 8:30 a.m. to 4:30 p.m. The post on filing an OIC complaint covers the steps.
Claims: new deadlines start Oct. 18, 2026
Washington's claim-handling rules change on Oct. 18, 2026. The OIC's permanent rule (WSR 26-17-089) rewrites parts of the unfair claims settlement practices rules in chapter 284-30 WAC. The biggest change for homeowners: the clock to accept or deny a claim now starts when you notify the insurer, not when you've sent a completed proof of loss.
| Step | Deadline from Oct. 18, 2026 |
|---|---|
| Acknowledge your claim | 10 business days |
| Approve an emergency mitigation scope (or send an approved one) | 5 business days |
| Finish the investigation | 30 calendar days after notice of claim, or written reasons, then a written update every 30 days |
| Accept or deny the claim | 30 calendar days after notice of claim (was 15 working days after a completed proof of loss); denial in writing citing the policy provision |
| Respond to your request for claim-file documents | 15 business days |
| Pay after you sign a release | 15 business days |
Source: WSR 26-17-089 (filed Aug. 18, 2026, effective Oct. 18, 2026); WAC 284-30-360, 284-30-330(16) and (20), 284-30-370, 284-30-380, 284-30-340.
Also new: an investigation can't rely solely on a database or estimating software. The Washington claim laws post goes through every change, plus appraisal and the Insurance Fair Conduct Act, which lets a policyholder who was unreasonably denied sue for actual damages and, at the court's discretion, up to three times actual damages (RCW 48.30.015).
If no one will write your house: the Washington FAIR Plan
When an agent can't place a house in the regular market, the OIC's answer is the Washington FAIR (Fair Access to Insurance Requirements) Plan. It provides basic property insurance up to $1.5 million if you can't get coverage
(OIC). Per the FAIR Plan, it's available anywhere in the state as long as the property is occupied and reasonably maintained. You get a quote through an agent.

Still small: 306 residential (habitational) policies in FY2024. But that's 4.5 times the 68 it had in FY2020. "Basic" is the word to notice: ask exactly what it covers compared with a standard homeowners policy, including liability.
What to check on your declarations page
The OIC's advice is to review your declarations page to make sure the policy has the coverage and amounts you asked for. Here's the list I'd go through at every renewal:
- Policy form. HO-3, HO-5 or something narrower. The form decides how broadly the house and your belongings are covered.
- Dwelling limit vs. rebuild cost. At least 80% of today's rebuild cost? Any extended replacement cost endorsement?
- Contents valuation. Replacement cost or ACV. And the special limits for jewelry, firearms and collections.
- Loss of use. Both the dollar limit and any time limit.
- Liability limit. $100,000 is common. Is it enough for what you own?
- Deductibles. The all-perils deductible, plus any separate earthquake deductible.
- Endorsements. Earthquake, sewer backup, ordinance or law, scheduled items. If it isn't listed, assume you don't have it. Flood won't be here at all; it's a separate policy.
- Mortgagee. Your lender listed correctly, so notices reach them and lender-placed insurance never comes up.
If you want a second pair of eyes on any of it, our Washington home insurance page has more on home coverage in this state, and the Washington insurance FAQ answers the common questions.
FAQ
Is homeowners insurance required in Washington state?
Not by state law. If you have a mortgage, your lender will require it, and if your coverage lapses the lender can buy lender-placed insurance that protects the lender and usually costs much more than your own policy.
How much is homeowners insurance in Washington state?
The newest verified state average is for 2022: $1,151 a year for an HO-3 policy in Washington, compared with $1,569 for the U.S., based on NAIC data published by Triple-I. Your own premium depends on location, construction, the amount of insurance, your credit-based insurance score and your claims history.
Does homeowners insurance cover earthquakes or floods in Washington?
Usually not. The standard HO-3 form excludes earth movement and flood. Earthquake coverage is an optional endorsement or separate policy with its own deductible, and flood coverage is a separate policy through the NFIP or a private insurer.
How much notice does a Washington insurer have to give before cancelling or not renewing a home policy?
At least 60 days' written notice that states the insurer's actual reason, for policies issued or renewed on or after July 1, 2025. Cancellation for nonpayment of premium needs 10 days' notice.
Your own policy wording and Washington law control what any policy pays. Confirm your situation with a licensed agent, the Washington Office of the Insurance Commissioner or, for legal questions, an attorney.
