Permitting & Inspections Department


The Permitting and Inspections Department serves as a one-stop permitting, licensing, and inspections shop, which centralizes services and reduces wait times. The department oversees building permits, code enforcement, business licensing, housing safety, rental regulation, and zoning.

The Department is responsible for the enforcement of the City’s building, plumbing, electrical, housing, solid waste and land use codes.  A combination of education and enforcement is crucial to protect the health, safety and welfare of all Portland residents and visitors. Each year, the Department reviews thousands of building plans and conducts thousands of inspections to ensure quality construction, safe housing and the proper use of the land.
