Washington Condo & HOA Calculators

Washington common-interest community calculators across the dual WUCIOA / Condominium Act regime split at July 1, 2018: the six-month assessment-lien super-priority under both RCW 64.90.485 (WUCIOA, post-2018 communities) and RCW 64.34.364 (Washington Condominium Act, 1990-2018 communities), the RCW 61.24 Deed of Trust Act 190-day nonjudicial sale notice timeline (the longest in the country), and the WUCIOA quorum, supermajority-vote, and resale-certificate disclosure thresholds.

Anchored to: RCW 64.90 (WUCIOA, post-2018); RCW 64.34 (Washington Condominium Act, 1990-2018); RCW 61.24 (Deed of Trust Act)
