Bill > SB5559

This bill aims to streamline the subdivision process inside urban growth areas by introducing new definitions and procedures for unit lot subdivisions. The bill adds several new terms to existing law, including "parent lot" (the original residential lot), "unit lot" (a subdivided lot within a residential development), and "unit lot subdivision" (a subdivision process for residential developments). The legislation requires cities and towns in urban growth areas to adopt procedures for unit lot subdivisions that include specific informational requirements on plats, such as noting the original project approval and potential future development limitations. The bill mandates that these procedures must use clear and objective design standards, avoid requiring public hearings, and provide notice to nearby property owners. Cities must implement these new requirements either in their next comprehensive plan update (for those updating in 2027) or within two years of the bill's effective date. The goal is to make the subdivision process more straightforward and predictable while ensuring that potential buyers are informed about the unique characteristics of unit lot subdivisions. By June 2026, all unit lot subdivisions will require specific notifications about their legal status, and the procedures aim to balance development flexibility with community awareness.
