Home Insurance in Washington: What It Costs and What Actually Covers You

Washington is a below-average state for home insurance cost, and it has two catastrophe perils that could plausibly produce the largest insured loss in state history.

Both things are true, and the way they fit together is the most useful thing to understand about insuring a home here.

Wildfire is real, it is getting worse, and it is fully covered by a standard policy under your ordinary deductible. The August 2025 Spokane fire destroyed roughly 700 homes and forced 60,000 evacuations, and for insured homeowners it was a fire claim - the same claim type as a kitchen fire, settled the same way, with the same $1,000 deductible.

Earthquake is the opposite. The Cascadia subduction zone is identified by the USGS as one of North America's most significant seismic threats, the Seattle Fault runs directly under the state's densest housing, and a standard Washington homeowners policy excludes earthquake entirely. It is a separate purchase, it carries a deductible in the tens of thousands of dollars, and only a minority of Washington homeowners have it.

So Washington's below-average premium is partly a real reflection of a functioning market, and partly an artifact of what is not in the policy. Both halves are worth knowing before you compare Washington's number to anyone else's.

This guide covers what the premium is, which deductible applies to what, what is covered and what is not, whether your Coverage A limit is anywhere near your rebuild cost, and what the state's FAIR plan actually does - which is considerably less than most people assume.

A note before you start: everything below is general information about how homeowners insurance works in Washington, not personalized insurance, legal, or financial advice. Policy forms, rates, and underwriting rules vary by carrier and by your individual circumstances - county, wildland-urban-interface exposure, roof age, construction type, distance to a fire station, and claims history all move the answer materially. For coverage specific to your property, talk to a licensed Washington insurance agent; for regulatory questions or complaints, the Washington Office of the Insurance Commissioner is the state authority.

1. What home insurance actually costs in Washington

The reference figure is $1,633 a year for $300,000 of dwelling coverage with a $1,000 deductible.

"Dwelling coverage" - labeled Coverage A on your declarations page - is the maximum the policy will pay to repair or rebuild the structure of your home. It is the anchor number for the entire policy, and as Section 2 explains, it is also what an earthquake policy's percentage deductible would be calculated from. $300,000 is a reference tier used so states can be compared on the same basis. As Section 4 explains, it is almost certainly not the right number for a Washington home.

The national average at that same $300,000 tier runs roughly $2,870. Washington reads about 43% below it.

Where the figure comes from

Two independent 2026 surveys quote Washington at the same $300,000 tier:

• Insurance.com's 2026 state rate table: Washington at $1,766, at $300,000 dwelling / $300,000 liability / $1,000 deductible.
• Insurify's 2026 state table: Washington at $1,500, at $300,000 dwelling / $1,000 deductible / $25,000 personal property / $300,000 liability, drawn from more than 180 carriers.

They disagree by about 15% - ordinary variation between quote-derived surveys with different carrier panels. Neither is stale, and neither is measuring a different tier, so both are treated as reasonable and averaged rather than one being discarded.

Corroboration at other levels: NerdWallet's May 2026 analysis puts Washington at $1,880 at $400,000 of dwelling coverage, higher as it should be at a higher limit. ValuePenguin's 2026 table reads $1,483 at $350,000, but that is a single-profile quote series rather than a market average.

Why Washington is cheap despite the wildfire risk

The honest answer has two parts, and one of them is uncomfortable.

The comfortable part: Washington's ordinary weather is mild by insurance standards. No hurricanes, no tornado alley, no Plains hail. Wind and rain losses are frequent but small. Most of what a homeowners policy pays for in most states - severe convective storm damage - barely happens here.

The uncomfortable part: the earthquake peril that would otherwise dominate Washington's risk profile is excluded from the policy being priced. A Cascadia rupture is among the largest single-event losses imaginable on the U.S. mainland, and none of that potential sits inside the $1,633. It sits in a separate market that most Washington homeowners have opted out of.

That is not a criticism of Washington's insurance market - the earthquake exclusion is standard almost everywhere. It is a caution about cross-state comparison. Washington's premium and, say, Oklahoma's are not measuring the same product.

Where the statewide average breaks down

Eastern Washington and wildland-urban-interface properties run above this figure. Western Washington suburbs run below it. After Spokane in August 2025, that gap is likely to widen rather than narrow.

The trend, and a genuine tension in the data

The projected change for 2026 is about +4.4% - Insurify's series has Washington moving from $1,533 in 2025 to a projected $1,600, and Insurify confirms 4.4% in its own Washington write-up. That is roughly in line with the +4% national figure in the same report.

Here is the tension, stated rather than smoothed over. The average requested homeowners rate change filed with Washington's Office of the Insurance Commissioner as of May 1, 2026 had dipped slightly below zero - about -0.5%. Carriers were, on average, asking for slightly lower rates.

Both numbers can be right at once. Filed rate requests measure what carriers want to charge for a given risk. The projection series measures what the average policyholder actually pays, which also moves when the mix of insured properties, dwelling limits, and coverage choices changes. A homeowner shopping mid-2026 may well not experience a 4.4% increase, and the negative filings describe a market that had been healing before the Spokane event landed.

Note that the dollar levels in the projection series are not comparable to the $1,633 headline: it models a median policy at each home's actual dwelling limit rather than a fixed $300,000 tier. Only the rate of change is used here.

2. The deductible that actually applies to your most likely claim

Here is the plain answer, and it is good news: there is no catastrophe deductible on a standard Washington homeowners policy.

That was checked, not skipped. Washington is absent from the National Association of Insurance Commissioners' list of nineteen states plus the District of Columbia with hurricane or named-storm deductibles in place. And no source consulted describes a separate percentage wind/hail deductible as an ordinary feature of a Washington homeowners policy either.

Your $1,000 all-perils deductible is the one that applies. To fire, wildfire, wind, hail, theft, vandalism, a burst pipe, a tree through the roof.

If you are coming to Washington from Colorado, Texas, or the Plains, understand how much of an improvement that is. In those states the deductible governing your most likely claim is a percentage of your dwelling limit - frequently 1% to 5%, which on a $500,000 home means $5,000 to $25,000 before the insurer pays anything. Here it is $1,000.

Do not assume it, though. Read your declarations page and confirm there is no separate wind/hail line. Percentage wind/hail deductibles have been spreading outward from the Plains, and "not a Washington convention" is a statement about the market, not a guarantee about your carrier's specific form.

Wildfire: covered under the ordinary deductible

This deserves to be stated flatly, because people assume otherwise and the assumption causes real anxiety.

Wildfire in Washington is a fire loss. Fire is a covered peril on every standard homeowners form, and a wildfire claim settles under your ordinary all-perils deductible - $1,000 in the typical case.

The August 2025 Spokane fire is the clearest available example. Driven by high winds, it jumped the Spokane River, destroyed roughly 700 homes, and forced 60,000 evacuations. For insured homeowners it was a standard fire claim - not a catastrophe-deductible event, because Washington policies do not have one.

What wildfire does affect in Washington is whether you can buy a policy at all, and at what price. That is an underwriting and appetite question, covered in Sections 5 and 6, not a deductible question.

Earthquake: the state's largest uninsured exposure, and it is outside the policy

A standard Washington homeowners policy excludes earthquake. This is standard almost everywhere. In Washington it is more consequential than almost anywhere.

Two hazards stack here:

• The Cascadia subduction zone, offshore, identified by the USGS as one of North America's most significant seismic threats and capable of a magnitude 8-plus rupture affecting the entire western half of the state at once.
• The Seattle Fault, a shallow crustal fault running directly beneath the densest housing and commercial value in the Puget Sound region. A shallow fault under a metro area produces very different - and in some respects worse - local shaking than a distant offshore rupture.

Earthquake coverage is available as a separate policy or endorsement, and it carries its own percentage deductible - commonly 10% to 25% of the dwelling limit in high-hazard western states.

Work it out. Section 4 puts a 2,000 square foot Washington home's rebuild cost at about $500,000. On a $500,000 dwelling limit:

• 10% = $50,000
• 15% = $75,000
• 20% = $100,000
• 25% = $125,000

And note the mechanic that catches people: the earthquake deductible is a percentage of the coverage limit, not of the loss. A 15% deductible on a $500,000 limit is $75,000 whether the quake did $80,000 of damage or $450,000 of damage. It is not "15% of the claim."

That has a direct consequence: earthquake insurance in Washington is catastrophe insurance, not repair insurance. It will not pay for a cracked foundation wall and a fallen chimney. It exists to keep a major event from destroying your entire net worth in a morning.

Only a minority of Washington homeowners buy it. That is a defensible individual decision - the premium is real money and the deductible is enormous - but it should be a decision, not an accident. It is the single largest uninsured exposure in the state, and if you have never priced it, you have not actually made the choice.

What to actually do about it

1. Confirm your declarations page shows a single flat all-perils deductible and no separate wind/hail line.
2. Confirm whether you have earthquake coverage. Look for a separate policy, a separate declarations page, or an earthquake endorsement named as such. If you cannot find one, you do not have it.
3. If you do have it, find the deductible percentage and multiply it out against your actual dwelling limit. Write the number down.
4. If you do not, get a quote before deciding. Ask specifically how your construction type changes the price - wood-frame homes on good soil price very differently from unreinforced masonry, and unreinforced masonry is a meaningful share of older Seattle, Tacoma, and Spokane housing. Ask also about soil liquefaction exposure if you are in a filled or low-lying area near the water, because it changes both price and expected damage.

3. What a standard policy covers here - and the gaps

A homeowners policy bundles several distinct coverages:

• Coverage A - Dwelling. The structure itself.
• Coverage B - Other Structures. Detached garage, shed, fence. Usually about 10% of Coverage A automatically.
• Coverage C - Personal Property. Your belongings, usually 50% to 70% of Coverage A.
• Coverage D - Loss of Use. What it costs to live elsewhere while repairs happen. After an event like the Spokane fire, where hundreds of households need housing in the same market at the same time, this coverage matters enormously and runs out faster than people expect.

Covered perils typically include fire (including wildfire), lightning, windstorm, hail, theft, vandalism, explosion, falling objects, weight of ice and snow, and sudden accidental discharge of water from plumbing.

Flood is never covered - anywhere, by anyone's homeowners policy

This is universal across all fifty states, not a Washington rule. No homeowners policy covers flood. Flood coverage is a separate purchase through the National Flood Insurance Program (NFIP) or a private flood carrier.

Washington's flood risk is more varied than people credit. Atmospheric river events produce riverine flooding on the Skagit, Snoqualmie, Chehalis, and Puyallup systems that has repeatedly reached disaster scale. Coastal and Puget Sound properties face tidal and storm-driven flooding. And post-wildfire debris flow is the Washington-specific hazard worth naming: a burn scar above a community sharply raises flood and debris-flow risk for years afterward, because the vegetation that used to absorb and slow runoff is gone. Debris flow and mudflow are flood-side perils, meaning the fire may be covered and the mudslide that follows a year later may not be.

Being outside a mapped high-risk flood zone is a statement about a flood map, not about whether your house can flood. A meaningful share of NFIP claims nationally come from outside high-risk zones.

Other exclusions worth knowing in Washington

• Earthquake. Covered above. Excluded, bought separately, 10% to 25% deductible.
• Landslide and earth movement generally. Excluded, and broader than earthquake. Washington's steep slopes, saturated winter soils, and coastal bluffs produce genuine slope-stability failures - the 2014 Oso landslide is the extreme case, but bluff and hillside failures around Puget Sound are routine. Standard policies do not cover them, and this is one of the larger uncovered exposures in western Washington after earthquake.
• Water damage from seepage or gradual leaks. In a wet climate, "sudden and accidental" versus "gradual" is the line that decides a lot of Washington claims. Long-term leaks are excluded.
• Mold, beyond limited sublimits - a live issue in western Washington's humidity and a frequent post-water-loss dispute.
• Maintenance and wear. Insurance covers sudden accidental damage, not deterioration. Moss, rot, and roof degradation are maintenance items, and a claim for a gradually failing roof will be denied.
• Ordinance or law - the extra cost of rebuilding to current code rather than as originally built. Washington's energy and seismic code updates make this a larger gap on older homes than people expect. Available as an endorsement; ask for it.
• Water backup from sewers and drains. Not covered by the base policy. Inexpensive endorsement, worth having.

4. Making sure you have enough coverage

The most consequential number on your policy is your Coverage A limit, and the most common way it goes wrong is setting it to your home's market value or your mortgage balance.

Neither is right. Dwelling coverage should equal the cost to rebuild your home from the foundation up at today's construction prices. Market value includes land, which does not burn. Your mortgage balance is a financing number with no relationship to construction cost.

In Washington, this error runs in both directions at once, which makes it unusually confusing. Washington's median home price is about $617,990, one of the highest in the country, and a very large share of that is land value in the Puget Sound corridor. Insure to market value and you are likely paying for coverage you cannot use. Insure to your loan balance and you are likely badly under-covered. The only number that matters is the construction cost.

Working a real Washington example

Rebuilding in Washington runs roughly $250 per square foot - the midpoint of a published $185 to $320 band covering materials, labor, and general contractor overhead and profit, excluding land.

On a 2,000 square foot home:

• 2,000 x $250 = $500,000 to rebuild

Take the band seriously:

• At $185/sq ft: $370,000
• At $320/sq ft: $640,000

Unlike most states in this dataset, Washington carries its own distinct cost band rather than sharing one with a group of neighbors - which is a modest point in the figure's favor. Still, the honest limitation: the source publishes cost bands, not surveyed averages, and no Washington building department or insurance regulator publishes a competing rebuild-cost survey to check it against. The $185-$320 spread is the honest width of this number.

Two other construction-cost series read Washington lower - $193 and $173 per square foot. Note that the $193 figure is the highest that series assigns to any state outside Hawaii, Alaska, California, New Jersey, New York, and Massachusetts, so it agrees that Washington is an expensive place to build. Both are also measuring a narrower quantity: they land near a $162 national figure that excludes general contractor overhead and profit. Rebuilding after a loss includes those, because you are hiring a contractor - often at post-disaster prices. That is why the higher figure is used here.

The market-value trap, worked

A 2,000 square foot Washington home costs about $500,000 to rebuild. The state's median home price is about $617,990.

If you insured that home to market value, you are carrying roughly $118,000 of dwelling coverage you cannot ever collect, because the lot survives every peril on the policy. You pay premium on it every year.

The reverse error is worse. A homeowner who bought at $617,990 with a $430,000 mortgage and insured to the loan balance is carrying $70,000 less than the rebuild cost and, as the next subsection shows, sits below the coinsurance threshold - which damages their small claims too.

Get an actual replacement-cost estimate for your specific home from your carrier or an independent estimator. In Washington this is genuinely worth doing, because the market-value and rebuild-cost numbers are far enough apart that guessing goes wrong in both directions.

The 80% coinsurance rule, and what a shortfall does to a partial claim

Most homeowners policies contain a coinsurance provision requiring you to insure the dwelling to at least 80% of its full replacement cost. Fall below that and the insurer does not merely cap your payout at your limit - it reduces every partial claim proportionally.

Work it on the example. Full replacement cost $500,000, so the 80% threshold is $400,000. Suppose you carry the $300,000 reference limit instead, and a fire does $80,000 of damage. Your limit is nearly four times the loss, so it feels safe. It is not:

• $300,000 carried / $400,000 required = 0.75
• 0.75 x $80,000 = $60,000
• Then subtract your $1,000 deductible
• Net payment: $59,000 on an $80,000 loss

You are $21,000 short on a claim comfortably inside your policy limit, entirely because Coverage A was set too low. None of it is visible until you file.

Two endorsements worth asking about by name

• Extended replacement cost - pays a stated percentage above your Coverage A limit (commonly 25% to 50%) when rebuilding costs more than expected. After a wildfire that destroys hundreds of homes in one area, contractor capacity vanishes and materials pricing moves sharply. Spokane in 2025 is exactly the scenario this endorsement is written for.
• Ordinance or law coverage - covers the extra cost of rebuilding to current code, which in Washington can include seismic, energy, and wildfire-related construction requirements triggered by a substantial rebuild.

5. Roof age, and why it decides your premium and your payout

An honest limitation first. This site's Washington data file records no statewide roof-settlement standard, because Washington does not set one by statute. Whether your roof is settled at replacement cost or actual cash value is decided by your policy form and your carrier's underwriting rules. So rather than tell you what your policy does, here is what to go find out.

The distinction to look for: ACV versus RCV

• Replacement cost value (RCV) pays what it costs to put a new roof on today.
• Actual cash value (ACV) pays replacement cost minus depreciation for the roof's age.

The gap widens every year. On a typical ACV depreciation schedule, a roof fifteen years into a twenty-year expected life has roughly 75% of its value depreciated away - the insurer pays about 25% of replacement cost and you fund the rest. Your deductible comes off the top of even that reduced amount.

Work it on a $22,000 roof replacement with a $1,000 deductible:

• On an RCV policy: the insurer pays $21,000.
• On an ACV policy with a 15-year-old roof at 75% depreciation: the loss is valued at roughly $5,500, minus the $1,000 deductible - the insurer pays about $4,500, and you fund $17,500.

Washington's flat $1,000 deductible means the ACV-versus-RCV gap is the whole difference here, rather than being compounded by a percentage deductible the way it is in hail states. That makes it simpler to reason about and no cheaper.

One Washington-specific warning: if you are placed with the Washington FAIR Plan, the question does not arise - every FAIR plan policy is actual cash value, full stop. Replacement cost is not offered. See Section 6.

Roof age in Washington is mostly an underwriting question

Because Washington does not have hail-state claim frequency, the more common way roof age hurts you here is on the front end: whether a carrier will write you, and at what rate.

Two state-specific pressures:

• Moss, moisture, and organic growth. Western Washington roofs age visibly, and an inspector's photograph of a moss-covered roof is a non-renewal risk regardless of the roof's chronological age. Regular cleaning and moss treatment is genuinely a maintenance-and-insurability item here, not cosmetics.
• Wildfire underwriting in the WUI. In or near wildland areas - which in Washington means much of the east side and a growing share of the west - carriers look hard at roofing material. A Class A fire-rated roof (asphalt composition, tile, or metal) is often a gating requirement. Wood shake is the opposite, and in high-risk areas it can make a property unwritable in the admitted market.

What to look for on the page

Open your policy's loss settlement section and find:

• A "roof surfaces" endorsement, or any actual cash value language applied specifically to the roof even where the rest of the dwelling is on replacement cost. This is the most common structure and the easiest to miss.
• A roof payment schedule depreciating payout by roof age and material.

Then ask your agent what a Class A fire-rated roof and documented defensible space would do for both your premium and your renewal prospects. In Washington, staying inside the admitted market's appetite is worth far more than any single discount, because - as the next section explains - the alternative is thin.

6. If no carrier will write you

Washington has a backstop. It is real, it takes no taxpayer money, and it is much narrower than most people assume. Understanding exactly what it is and is not is the point of this section.

Washington FAIR Plan Association

The Washington FAIR Plan Association (wafairplan.com) is the state's insurer of last resort. It was established in 1968 under Chapter 284-19 WAC and operates as a joint reinsurance association that every property insurer licensed in Washington must belong to. It takes no taxpayer funding - this is the industry backstopping itself under regulatory supervision - and it is overseen by the Office of the Insurance Commissioner.

The critical point: it is not a homeowners policy

This is the thing to internalize before you need it. The Washington FAIR Plan does not write homeowners insurance. It writes a much narrower property policy.

What it covers:

• Basic fire and lightning on dwellings and commercial buildings. That is the core product.
• Extended Coverage is available as an add-on, bringing in wind, hail, explosion, riot, aircraft, vehicles, and smoke.
• Vandalism is a further separate option.
• Wildfire is paid as a fire loss under ordinary fire-policy terms - which is the one place the FAIR plan lines up cleanly with what a standard policy would have done.

What it excludes outright:

• Liability. No personal liability coverage at all. If someone is injured on your property, this policy does nothing.
• Theft.
• Water damage. Including the burst-pipe losses that are among the most common homeowners claims in the country.
• Flood.

How it settles:

Policies are written exclusively on an actual cash value basis. Replacement cost is not available. Depreciation comes out of every claim payment. On a 25-year-old house with a 15-year-old roof, that is not a small adjustment - it is the difference between rebuilding and not.

Limits and eligibility:

• Coverage is capped at $1.5 million per location. For most Washington homes that cap is not the binding constraint - Section 4 puts a 2,000 square foot rebuild at about $500,000 - but it is a real ceiling on high-value property.
• Available anywhere in the state, provided the property is occupied and reasonably maintained.
• No fixed number of prior declinations is required, unlike some states' plans.
• Autos, farm risks, and manufacturing risks are ineligible.

What the usage numbers tell you

Roughly 306 habitational policies were in force as of May 2026, having plateaued near 400 over the preceding three quarters.

That is a very small number for a state of Washington's size, and it is the most honest signal in this section: Washington's admitted market is still writing most risks. The FAIR plan here is a bridge for a few hundred properties, not a destination for a collapsing market - which is a genuinely better situation than the one in California or Florida.

Whether the Spokane fire moves that number is being watched by state officials but is not yet in the data. If you are reading this a year from now, it is worth checking again.

The right way to think about it

The Washington FAIR Plan is protection against having nothing, and specifically against losing your house to fire with no insurance at all. It is not a substitute for a homeowners policy, and treating it as one will leave you exposed on liability, theft, and water damage simultaneously.

If you end up there:

1. Buy the Extended Coverage and vandalism options. The base fire-and-lightning-only policy is very thin.
2. Buy liability separately. A standalone personal liability policy or an umbrella that does not require an underlying homeowners policy is worth investigating, because the FAIR plan gives you none.
3. Understand you are on ACV. Set expectations accordingly and keep the property in good enough condition to get back into the admitted market.
4. Re-shop the voluntary market at every renewal. With only a few hundred policies statewide, the admitted market is clearly still writing - which means getting back in is realistic.

7. How to actually lower your premium in Washington

Ranked roughly by how much they move the number in this state specifically.

1. Do wildfire mitigation, and document it. Defensible space out to 100 feet where you have the lot for it, a Class A fire-rated roof, ember-resistant vents, non-combustible siding in the first several feet, gutters kept clear, and nothing combustible stored under decks. In Washington these increasingly affect whether you get written, not just what you pay - which makes them worth more than any discount. Take dated photographs, keep receipts, and give them to your carrier proactively rather than waiting to be asked.

2. Get your Coverage A limit right - in both directions. With a median home price around $617,990 and a 2,000 square foot rebuild cost around $500,000, some Washington homeowners are meaningfully overinsured and paying for coverage they cannot collect, while others insured to a loan balance are badly short. Get an actual replacement-cost estimate. This is the rare adjustment that can lower your premium and improve your coverage.

3. Raise your deductible - and note this is a clean trade in Washington. Moving from $1,000 to $2,500 lowers your premium and raises your exposure by $1,500 on any claim. In a percentage-deductible state this decision is entangled with a separate wind/hail deductible; here there is only the one number. For most households with a reserve, $2,500 is a sensible landing point.

4. Keep the roof clean and current. This is more of a Washington item than it sounds. Moss removal and roof maintenance directly affect inspection outcomes, and inspection outcomes drive non-renewal. A roof that would have been fine at 18 years can present as failed at 14 if it has been growing a garden. It is cheap maintenance with an outsized insurability effect.

5. Bundle home and auto. Multi-policy discounts remain among the largest routinely available, and as WUI underwriting tightens, being a multi-policy customer helps on the appetite side too.

6. Stop filing small claims. With a $1,000 deductible, most small losses are barely worth claiming. Claims frequency drives non-renewal, and given how narrow the FAIR plan is, being pushed out of the admitted market in Washington is a much larger downgrade than it appears. Paying a $2,500 repair yourself is often strictly better than a claim that nets you $1,500 and marks your record.

7. Ask about the credits nobody offers unprompted. Monitored alarm and fire systems, automatic water-shutoff devices (particularly relevant given how much Washington claim activity is water), updated electrical, plumbing, and HVAC on older homes, new-roof credits, new-home credits, and claims-free longevity. Ask item by item, and ask which need documentation.

8. Shop earthquake coverage on its own merits. This raises your total spend rather than lowering it, and it belongs on the list because the cheapest possible homeowners premium is meaningless against the one peril that could take the whole house and your equity with it. Get a quote. Ask what the deductible percentage is, multiply it out, and ask specifically how your construction type and soil affect price and availability. Then decide knowingly rather than by default.

9. Consider flood if you are below a burn scar, on a river system, or on the water. Post-fire debris flow and atmospheric river flooding are both genuine Washington hazards, and both are flood-side perils. In moderate-risk zones NFIP premiums are often far below what people assume.

10. Re-shop every year or two, and compare the right four things. Line them up: the premium, the dwelling limit, the deductible - and confirm no separate wind/hail line has appeared in the new quote, and the roof settlement basis (RCV or ACV). A quote that beats yours on premium by moving your roof to actual cash value is not a better quote.

What to do next

If you want these numbers applied to your actual house rather than a statewide average, the Washington premium calculator estimates your annual cost from your own dwelling limit and deductible. The replacement cost calculator works out the Coverage A limit you actually need from your home's square footage using Washington construction costs - the first thing to check in this state, given how far Washington market values sit above Washington rebuild costs and how easily that produces both over- and under-insurance. And while a standard Washington policy has no percentage catastrophe deductible, the deductible calculator is the fastest way to see what a 10%, 15%, 20%, or 25% earthquake deductible would mean in real dollars against your specific dwelling limit.

All three show every figure they use and where it came from.

This guide is general information about homeowners insurance in Washington, based on publicly available figures current as of August 2026. It is not an insurance quote, a policy, coverage advice, or legal advice, and it does not reflect your individual property, county, wildland-urban-interface exposure, roof age, claims history, or carrier's specific policy language. Premiums, earthquake coverage availability and pricing, FAIR plan terms, and underwriting rules vary substantially by carrier and by property, and Washington does not set roof settlement by statute. For coverage specific to your home, speak with a licensed Washington insurance agent; for regulatory questions or complaints, contact the Washington Office of the Insurance Commissioner.
