WUCIOA: a practical guide for Washington HOA boards and homeowners
A plain-English breakdown of the Washington Uniform Common Interest Ownership Act (RCW 64.90) — including the January 1, 2028 deadline that will bring every Washington HOA under this law.
Washington homeowners associations are in the middle of a multi-year legal transition. Older communities have long operated under RCW 64.38, a shorter, more general HOA statute. But the Washington Uniform Common Interest Ownership Act (WUCIOA), codified at RCW 64.90, is a much more comprehensive framework — and by law, every common interest community in Washington must be operating under WUCIOA by January 1, 2028.
That deadline is not widely understood by boards yet, which makes it one of the most useful things a management company can help a Washington HOA get ahead of. WUCIOA expands requirements around reserve studies, resale certificates, budget disclosures, and meeting procedures well beyond what RCW 64.38 required.
The four areas that matter most under WUCIOA
The 2028 WUCIOA Transition
Every Washington common interest community — regardless of when it was formed — must be governed by WUCIOA (RCW 64.90) by January 1, 2028. Associations still operating under RCW 64.38 need a transition plan: updated governing documents, reserve study compliance, and revised disclosure practices.
Reserve Studies
WUCIOA requires associations to conduct a reserve study and keep it updated, with specific funding disclosure requirements tied to the study. This is a meaningfully higher bar than many older Washington HOAs have historically met.
Resale Certificates
When a unit or lot sells, WUCIOA requires the association to provide a detailed resale certificate covering financial condition, pending litigation, insurance, and rule violations — with statutory timelines the seller and buyer are entitled to rely on.
Meetings & Budget Disclosure
WUCIOA sets requirements for open meetings, member notice, and annual budget ratification, including disclosure of reserve funding adequacy — giving homeowners more visibility into the association's financial health than RCW 64.38 required.
Knowing the law and following it are different problems
- Reserve study conducted and kept current per WUCIOA funding disclosure requirements
- Resale certificates prepared accurately and within statutory timelines
- Annual budget ratification and meeting notice procedures documented
- Governing documents reviewed against the 2028 WUCIOA transition deadline
- RCW 64.38 legacy associations given a clear transition roadmap
We manage HOAs and condo associations across Washington — Seattle, Spokane, Tacoma, Bellevue, and Vancouver — with WUCIOA compliance and the 2028 transition built into every management cycle.
