The 1990 Condominium Act (RCW 64.34) governs 1990–2018 condos. The 1995 HOA Act (RCW 64.38) governs pre-2018 planned communities. SB5796 (2024) and SB5129 (2025) are phasing WUCIOA in across all associations by 2028. The state requires reserve studies for associations with significant assets, mandates a detailed condo resale certificate with a 5-business-day buyer rescission right, and is rolling out new open-meeting and pre-foreclosure rules starting January 2026. Cascadia subduction-zone seismic exposure, increasingly stressed insurance economics, and aging Seattle high-rise stock are the leading risk drivers.
Cascadia earthquake exposure across Puget Sound
The Cascadia subduction zone runs offshore from the Pacific Northwest. Washington's I-5 corridor — Seattle, Bellevue, Tacoma — faces concentrated seismic exposure. Earthquake coverage is not statutorily required and is typically a separate rider with high deductibles. Many associations decline it entirely, leaving owners exposed to substantial post-event loss-assessment risk.
Reserve studies required, funding not
Both RCW 64.34 and RCW 64.38 require reserve studies for associations with significant assets — initial study by professional inspection, annual updates, and on-site updates at least every 3 years (RCW 64.34.380, RCW 64.38.065). WUCIOA continues these requirements. The statutes do not require funding to a specific level. Many associations carry up-to-date studies but underfunded reserves.
Detailed resale certificate with 5-day rescission
RCW 64.34.425 requires a condo resale certificate covering assessments, financials, reserve balances, insurance, litigation, and governing documents. The buyer has 5 business days to rescind after first receiving the certificate. This is one of the stronger statutory disclosure regimes among Western states. WUCIOA RCW 64.90.640 imposes parallel requirements on newer associations.
Three coexisting statutes through 2028
Until WUCIOA fully consolidates the regime by 2028, the first diligence question is which statute governs. RCW 64.90 (post-2018), RCW 64.34 (1990–2018 condos), or RCW 64.38 (pre-2018 HOAs) — each with materially different reserve, governance, lien, and insurance provisions. Verify in the declaration before assuming any statutory protection.
2026 governance reforms (SB5129 + SB214/2023)
Starting January 1, 2026, SB5129 requires all associations to hold open meetings and use ballot voting (banning email voting for major decisions). SB214/2023 adds detailed pre-foreclosure notice requirements once an owner is 90+ days delinquent or owes $2,000. Boards preparing for compliance ahead of the effective date are demonstrating governance discipline. Boards deferring engagement may not be.
