The Washington State Department of Commerce is updating administrative rules for the Growth Management Act to address recent legislation on housing, permitting, development regulations, urban growth areas, and rural development.
Growth Management Services (GMS) is actively working with local governments and other stakeholders to ensure local comprehensive plans and development regulations plan for and accommodate housing affordable to all economic segments of the population in Washington. Planning for housing now requires an inclusive and equity-driven approach to meet the housing needs for all residents at all income levels. Rulemaking will reflect recommendations in the technical guidance that GMS developed to support local government planning for increased densities, housing types, and considerations of displacement, exclusion and racially disparate impacts in local housing policies.
