In recent years, the governance of Washington’s common interest communities (CICs) 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 common interest communities (CICs) 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 communities largely exempt until January 1, 2028. This led to a fragmented system of inconsistent standards across the state. 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.
What is SB 5129?
SB 5129 is a law that accelerates the application of WUCIOA provisions to CICs, modifies key provisions of WUCIOA, and extends WUCIOA’s reach to smaller communities that were previously exempt.

Extension of WUCIOA Provisions to Smaller Communities
Prior to SB 5129, plat and miscellaneous communities were automatically exempt from most WUCIOA provisions if they had 12 or fewer units and annual assessments of $300 or less per unit. (A miscellaneous community refers to a common interest community that is not classified as a condominium, cooperative, or plat community, but where units were lawfully created under Chapter 58.17 RCW—Washington’s Subdivision Act.)
Communities that met these criteria were only required to comply with the following 3 provisions: RCW 64.90.020 (separate taxation and classification of units as real property), RCW 64.90.025 (equal treatment under local building and land use laws regardless of ownership type), and RCW 64.90.030 (procedures and compensation rules related to condemnation and eminent domain). SB 5129 significantly expands both the exemption thresholds and applicable WUCIOA provisions. The thresholds increased to 50 or fewer units and annual assessments of $1,000 or less per unit.
The chart below outlines the additional WUCIOA provisions that will now apply to these communities:

Takeaway
SB 5129 marks a major step in how Washington regulates CICs. By modifying key WUCIOA provisions and expanding its reach, the law brings long-overdue consistency and modernization to HOA operations statewide. While it may take some adjustment, the long-term benefits of SB 5129 are clear: stronger communities, better-managed associations, and homeowners with greater influence.
