Which law governs your association today
| Date | What happened |
| 1 July 2018 | WUCIOA (RCW 64.90) took effect. It fully governs associations created on or after this date. |
| 1 January 2026 | A list of ten WUCIOA sections began applying to associations created before 1 July 2018 (RCW 64.90.365(1)). This did not make WUCIOA fully apply to anyone. |
| 1 January 2028 | WUCIOA applies to every common interest community (RCW 64.90.360(2)). The old chapters, RCW 64.32, 64.34 and 64.38, are repealed. |
Until 2028, an older association runs on its old chapter: homeowners associations on RCW 64.38, condominiums created before 1990 on RCW 64.32, and condominiums created from 1990 on RCW 64.34, plus the ten sections that already reach back.
Your board may be quoting dead section numbers. In 2024 the key sections were renumbered: RCW 64.90.075 is now 64.90.360, 64.90.080 is now 64.90.365, and 64.90.095 is now 64.90.370. Memos written before mid-2024 usually use the old numbers.
The ten sections that already reach older associations
Since 1 January 2026, older associations must follow WUCIOA on: the opt-in route (64.90.370); the duty to adopt budgets and impose assessments (64.90.405(1)(b) and (c)); meetings (64.90.445); a free way to pay assessments (64.90.480(10)); emergency powers (64.90.502); EV charging (64.90.513); budget ratification (64.90.525); reserve studies (64.90.545); heat pumps (64.90.580); and the definitions needed to read them (64.90.010).
Reserve studies can't be waived
RCW 64.90.545 requires a reserve study, updated every year, with a professional update and site visit at least every third year. The words "waive" and "waiver" do not appear in the section, so an annual vote to waive the study has no basis in the statute. It applies to older associations too. Owners holding at least 20% of the votes can demand a study when more than three years have passed since the last professional one (RCW 64.90.555).
Silence means yes on budgets
Under RCW 64.90.525 a budget, or a special assessment, is ratified unless owners holding a majority of all the votes in the association vote to reject it. No quorum is needed at that meeting.
New in 2026
From 11 June 2026, a resale certificate costs no more than $275 to prepare and $100 to update within six months (RCW 64.90.640). From the same date, an owner who sends a written question by certified mail is entitled to a substantive written answer within 30 days (RCW 64.90.715).
