Do I need a permit for shed or accessory structure 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.
It depends. Whether shed or accessory structure needs a permit in Keizer comes down to the details of your project.
The ORSC exempts nonhabitable one-story detached accessory structures up to 200 square feet and 15 feet tall from a building permit statewide (R105.2 item 1); on a parcel of 2 acres or more, a structure at least 20 feet from all property lines and regulated structures may be up to 400 square feet. Anything larger, taller, habitable, or attached to the house needs a building permit. A building permit exemption does not waive zoning setbacks or land-use approval, and separate electrical or plumbing permits may still be required.
