Verify Wildfire Zone Status

Check if your property is in a wildfire hazard zone — additional roofing material and exterior requirements apply in these areas.

Submit your permit application through Portland's online portal or visit the Development Services Center at 1900 SW 4th Ave. Free 15-minute consultations are available.

Pay Fees & Await Review
