New SEPA Exemption for Housing Proposals
Seattle has made considerable progress in planning for housing growth in both its comprehensive plan and land use codes. In recognition of that progress, the Washington State Legislature has amended (Senate Bill 5412) the State Environmental Policy Act (SEPA) to help reach those goals by expediting the review of development that includes housing. As of July 23, 2023, most projects proposing additional housing units will be exempt from SEPA review, including several types of residential and mixed-use developments that would have previously undergone SEPA review. This SEPA change does not affect other SDCI discretionary approvals, such as Design Review, that may be required for specific proposals. This SEPA amendment will be in effect until September 30, 2025, when the Seattle Comprehensive Plan Update provides new housing growth targets and updated SEPA thresholds.
