Fences

The information on this page contains an overview of requirements for adding a fence to either residential or commercial property.

Getting Started

A building permit is required when building a fence taller than seven feet. The height is measured from the ground where the posts or supports enter the ground to the top of the fence, including any lattice, posts or any other material added to the top. Fences under six feet tall do not need a building permit but may need a zoning permit, depending on where the fence will be located on your lot.

For more information, visit the Planning and Zoning staff at the Development Services Center or call (503) 823-7526.

Your building permit will be reviewed under provisions in the Residential Specialty Code (formerly the One and Two Family Dwelling Specialty Code) based on the 2003 IRC.  More information on building codes.
