Portland Fence Permit Guide

Portland fence permits depend on height, zoning overlays, plan districts, erosion control, tree protection, and final inspection requirements.

Permit takeaway

Portland says fences more than seven feet high need a building permit, while fences less than seven feet high generally do not.

Zoning and placement

Overlay zones or plan districts may create alternative standards or zoning permit requirements.

Building and trade review

When a fence permit is issued, Portland provides an inspection card and requires final approval inspection to complete the permit.

Call before applying when

Call before applying if the fence is over seven feet, in an overlay zone, close to trees, near slopes, or part of ground-disturbing work.
