Getting Started

A demolition permit is required to demolish any building that required a building permit. Structures exempt from a building permit to construct do not require a permit for demolition. Structures that should have been constructed under permit, but were built without benefit of a permit, will require a demolition permit for removal.

A demolition permit is issued when the entire building is being demolished. The removal of a portion of a building is considered an alteration to that structure, and is usually reviewed and permitted as part of a larger project, not as a stand-alone permit. For more information about determining if your project is a demolition, alteration/remodel, or addition, please visit the Development Services Center.

Each structure removed requires a separate permit. For example, a detached garage and house on the same property will require two separate demolition permits.

A separate demolition permit is required even when a permit is being issued simultaneously to construct a new building in its place.

Erosion control inspections are required for each permit issued. Your permit will be reviewed under various code provisions, including Chapter 24.55 of the Portland Zoning Code. View more information on building codes.

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.
