Welcome to the Bureau of Development Services (BDS) Maps & GIS website. This website is the Bureau’s location for Portland Maps and GIS tools that provide access to information about private property, land use reviews, permits and enforcement cases administered by the Bureau, as well as information on how to use Portland Maps search functions. If you are not able to find information through the resources provided on this page, complete property records maintained by BDS can be requested through the Bureau Public Records Access webpage.
The Portland Maps and the BDS Permit/Case Search can be used to find active and historical building permit, trade permit, land use review and enforcement case information (from 2000 to present).
BDS staff have created two how-to search Portland Maps guides that provided step-by-step instruction on how to navigate to information available in the BDS Permit/Case Search interface.
BDS has created a number of “thematic” maps of more popular BDS records, including residential demolitions, assessor short term rentals and recent enforcement cases.
