Washington condo insurance requirements
Insurance is the defining risk in a Washington condo purchase, driven by Cascadia earthquake exposure. Washington condominium associations must carry master property insurance covering at least 80% of replacement value plus liability coverage, under RCW 64.34.352.

HOAs under RCW 64.38 have no explicit state insurance minimum — most declarations require coverage, but the actual policy must be verified. Critically, earthquake and flood are not mandatory and are frequently excluded or carry high deductibles (earthquake deductibles commonly run 5–15% of insured value). Associations often choose high master deductibles ($25,000–$100,000), and many declarations shift the deductible to the responsible unit owner after a loss. For a buyer, the master policy is both a risk document and a financing document — read it closely.
What RCW 64.34.352 requires of condominiums
For condominiums, RCW 64.34.352 requires the association to maintain, to the extent reasonably available, property insurance on the common elements (and on units to the extent the declaration provides) covering at least 80% of the full replacement value of the insured property, plus liability insurance covering the common elements. The 80%-of-replacement-value floor is the statutory baseline — coverage below it is a red flag worth raising before you commit. HOAs and planned communities under the 1995 HOA Act (RCW 64.38) have no equivalent statutory insurance minimum; their coverage obligations come from the declaration and CC&Rs, so for an HOA-governed community the only way to know what is covered is to read the governing documents and the actual policy. That makes the condo-versus-HOA classification the first insurance question to answer, because it determines whether a statutory coverage floor even applies.
Cascadia earthquake — the defining Washington exposure
The Cascadia Subduction Zone is the top insurance risk statewide, concentrated in the Puget Sound metros — Seattle, Tacoma, Bellevue, and Everett — and aggravated by aging condo stock built in the 1970s through 1990s, where roofs, decks, building envelopes, and parking garages are reaching end of life. Earthquake coverage is not mandatory and is frequently excluded from the master policy or carried with a high deductible commonly running 5–15% of insured value. A condo with no earthquake coverage in a Cascadia zone leaves owners exposed to a catastrophic uninsured loss, and a 10%-plus earthquake deductible can mean a five- or six-figure out-of-pocket exposure spread across owners as a special assessment after a quake. Confirm whether earthquake coverage is carried, at what deductible, and how the declaration apportions that deductible among owners after a loss.
Flood, wildfire, deductibles, and the FAIR Plan
Beyond earthquake, Washington carries flood exposure on Puget Sound and along rivers like the Skagit, and eastern Washington (Spokane, Wenatchee) adds wildfire and freeze-thaw stress. Flood, like earthquake, is generally excluded from master policies, so owners in mapped FEMA flood zones should confirm separate flood coverage. Associations often run high master deductibles of $25,000 to $100,000, and many declarations shift a per-unit or unit-originated deductible onto the responsible owner after a loss. The Washington FAIR Plan is the last-resort fire and wind insurer for properties that cannot obtain coverage in the standard market — a master policy placed through the FAIR Plan signals a stressed situation worth examining. As of 2024 the Office of the Insurance Commissioner requires insurers to explain large premium increases, which helps buyers understand a master-policy spike.
Read the master policy against your own HO-6
Pull the master-policy declarations page and read it as both a risk and a financing document, then read your own HO-6 against it. Many Washington declarations push unit-originated claim deductibles — a water leak from a unit, for example — onto the responsible owner, and large blanket deductibles may be apportioned among owners, so your HO-6 loss-assessment coverage matters more than buyers expect. Confirm whether earthquake and flood are covered, at what deductibles, and how those deductibles flow to owners. A high master deductible also collides with Fannie Mae and Freddie Mac financing standards, so the same declarations page that defines your earthquake risk may also determine whether the project is warrantable. In Cascadia country, the gap between what the master policy covers and what an owner ultimately pays is the heart of Washington condo insurance risk.

- Determine whether the property is a condo (RCW 64.34.352 applies) or an HOA (CC&Rs control)
- For a condo, confirm master property coverage at no less than 80% of replacement value plus liability
- For an HOA, read the CC&Rs and the actual policy — no statutory floor exists
- Confirm whether earthquake coverage is carried, and at what deductible (commonly 5–15% of value)
- Confirm how the declaration apportions the earthquake / master deductible among owners after a loss
- Pull the master-policy declarations page and note the master deductible ($25K–$100K is common)
- Confirm flood coverage and FEMA flood-zone status; master policies generally exclude flood
- Check whether the master policy is placed in the standard market or through the WA FAIR Plan
- Review the master-policy premium trend (OIC requires insurers to explain large increases)
- Review your own HO-6 loss-assessment limit against the master deductible and any owner-shifted deductible
