RCW 64.90
—
The Washington Uniform Common Interest Ownership Act (WUCIOA). Enacted in 2018 (Chapter 277, Laws of 2018), WUCIOA replaces the patchwork of pre-existing condominium and HOA regimes (RCW 64.32, 64.34, 64.38) with a single unified statute based on the Uniform Common Interest Ownership Act. Initially governed only communities with declarations recorded on or after July 1, 2018; ESSB 5796 (2024) extends WUCIOA to every Washington common interest community by January 1, 2028, regardless of formation date. SB 5129 (2025) accelerates several key provisions to January 1, 2026.

Governance
| Ref | Requirement |
|---|---|
| (chapter) | By January 1, 2028, every condo and HOA in Washington — no matter how old — must operate under WUCIOA. Boards governing pre-2018 communities need a compliance plan now to identify governing-document provisions inconsistent with WUCIOA. |
| (chapter) | Several WUCIOA provisions don't wait for 2028 — SB 5129 made them apply to every Washington HOA and condo starting January 1, 2026. Most notable is the fee-free payment-method requirement, which forces every association to offer at least one way to pay assessments without a third-party processor fee. |
| (chapter) | WUCIOA is the new master statute for HOAs and condos in Washington. It replaces three separate older statutes with one consistent set of rules. Every community will operate under WUCIOA by 2028. |
| (chapter) | When WUCIOA first took effect in 2018, only newly created communities were bound by it. Older condos and HOAs kept operating under their original statutes — until the 2024 transition law changed that. |
