The Department of Planning and Development (DPD) issues two types of permits, Master Use Permits (MUPs) and Construction Permits.
In general Master Use Permits assure that structures meet zoning requirements and comply with environmental regulations, such as the State Environmental Policy Act (SEPA) and the Seattle Shoreline Master Program. Components of a MUP may also include use approvals, variances, administrative conditional uses, design review, special exceptions, shoreline district approvals, short plats, and certain street uses.
Construction Permits assure that the structural and fire/life safety elements of your project are in compliance with the latest adopted code.
DPD has several Client Assistance Memos (CAMs) available to help guide applicants through the permitting process.
