POL Government Bureaus & Offices Development Services Permits Residential Enlarging the Building Footprint
Getting Started

Building permits are required for building an addition to a single-family dwelling. This includes enclosing a porch and adding new living space to your home by enlarging the footprint of the original building. Depending on the scope of work, your project may also require electrical, plumbing or mechanical permits.

 

View more information if your project will also involve the addition of a garage.

Your permit will be reviewed under provisions of the current Oregon Residential Specialty Code.

It is recommended to visit or call the Planning and Zoning staff (503) 823-7526 and Buildings staff (503) 823-7310 at the Development Services Center early in the planning of your project.
