SB 5633 Washington Senate · 2025-2026 Regular Session

Concerning the subdivision of land.

SB 5633 updates Washington's outdated land subdivision laws (originally enacted in 1969) by creating a new Chapter 58.17A RCW to replace 30+ existing sections. It streamlines the process by merging the obsolete "short plat" and "subdivision" procedures into one uniform system, requiring local governments to integrate subdivision reviews with Growth Management Act (GMA) and SEPA requirements. The bill directly affects cities, towns, and counties that approve land divisions, aiming to expedite approvals for housing projects while ensuring standards for public safety, infrastructure, and housing needs. Its key provision simplifies the subdivision approval process to address Washington’s housing supply crisis, as explicitly stated in the bill’s legislative findings.
