Summary: This Tip explains the processes and requirements for the Seattle Department of Construction and Inspections (SDCI) addressing reviews. SDCI is responsible for assigning all addresses for the city of Seattle, and for adding addresses to the discrete address point (DAP) layer in the geographic information system (GIS). The DAP layer allows some governmental and non-governmental agencies the ability to locate properties within the city with a high degree of certainty so that services, including emergency response, may arrive to an accurate location in a timely manner.
