Do I need a permit for basement finishing in Keizer?
Keizer does not issue residential building permits. Keizer does not run its own building program. The Oregon Building Codes Division Local Building Department Directory lists Marion County as the building department for Keizer for all permit types (structural, mechanical, electrical, plumbing). The City of Keizer Building Permit Division takes applications at City Hall for single family homes, residential remodels and accessory structures on Marion County permit forms; Marion County Building Inspection (5155 Silverton Rd NE, Salem, 503-588-5147) handles plumbing with plan review, septic, deferred submittals, re-inspections and electrical with plan review.
The requirements below come from Oregon rules and describe the standard the work must still meet. They are not a statement that Keizer will issue you a permit.
Yes. In Oregon, basement finishing generally requires a permit, and Keizer is no exception.
Creating new habitable space, a new toilet room, or a new bathroom requires a building permit (ORSC R105.1.1), and BCD lists finishing a basement to make additional living space as permitted work. Oregon kept its long-standing rule that basements and every sleeping room need an operable emergency escape and rescue opening; where a basement has sleeping rooms, each one needs its own (ORSC R310.1 as amended effective Oct. 1, 2024). Turning an unconditioned basement into conditioned space is a change of use under ORSC N1101.2.3, and the permitted work triggers smoke alarms (R314.2.2) and carbon monoxide alarms (R315.2.2) for the dwelling.
