Do I need a permit for shed or accessory structure in Unincorporated Tillamook County?
It depends. Whether shed or accessory structure needs a permit in Unincorporated Tillamook County 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.
