Garage, Shed, Accessory Structures

Information relating to small, non-habitable structures on the same property such as a house or duplex.

Getting Started

A building permit is required to build, demolish or move any carport, garage or shed that is greater than 200 square feet in area or greater than 10 feet high measured from the finish floor level to the average height of the roof. Depending on the scope of work, your project may also require electrical, plumbing or mechanical permits.

A building permit is not required to construct an non-habitable accessory structure that is 200 square feet or less in area. However, a zoning permit could be required.

It is recommended to visit or call the Planning and Zoning staff (503) 823-7526 and Buildings staff (503) 823-7310 option four (4) at the Development Services Center early in the planning of your project.
 
Your permit will be reviewed under provisions in the current Residential Specialty Code (formerly the One and Two Family Dwelling Specialty Code).
