In recent years, the governance of Washington’s HOAs has become a growing concern for both lawmakers and residents. To address this concern, the state enacted the Washington Uniform Common Interest Ownership Act (WUCIOA) in 2018, establishing modern standards for how HOAs should operate.

However, the law only applied to communities formed after its passage and to existing communities that chose to opt in, leaving many older HOAs largely exempt until January 1, 2028. To address these disparities sooner, the legislature passed Senate Bill 5129 (SB 5129), which begins taking effect July 27, 2025, with full implementation by January 1, 2026.
