Missing Middle Housing Project
Missing Middle Housing Update
Project Overview
In 2023, The Washington Legislature passed the Engrossed 2nd Substitute House Bill requiring 77 jurisdictions across the state to adopt development regulations allowing for middle housing on all lots zoned for residential use. Additionally, House Bill 1337 mandates the adoption or amendment of municipal zoning regulations to permit at least two accessory dwelling units (ADUs) on all lots within urban growth areas that allow for single-family homes. The City is currently in the process of developing policies, zoning, and development standards to facilitate missing middle housing and the ADU requirements.
