How Tall Can a Fence Be Without a Permit in Portland?

In Portland, the number that matters is 7 feet: a fence taller than that needs a permit from the Portland Permitting & Development, while anything at or under it can usually go up without one. That cutoff covers standard residential fences; retaining walls, pool barriers, and masonry walls typically follow their own rules, so flag those to the department separately. Even a permit-free fence still has to respect setbacks and corner sight-line rules, so check placement before you dig post holes.

Do You Need a Permit to Build a Fence in Portland?

For a typical backyard fence at or under 7 feet, no — you can skip the building permit in Portland. Go taller and you'll file with the Portland Permitting & Development, with permit fees typically in the No permit fee range. Two cautions before you skip the paperwork: zoning rules (height caps, setbacks, corner visibility) apply to every fence, permitted or not, and HOA or deed rules stack on top of city code. When your plan sits close to the line, a quick call to the department beats rebuilding a fence later.
