Installing a fence in Oregon means dealing with wet soil, permits, and material choices. Learn what works in the Pacific Northwest.
Oregon Is Hard on Fences
A cedar fence in Salem will last decades. A pressure-treated pine fence in the same location might be rotting in 7 years if not maintained. Oregon's moisture levels make fence material selection one of the most important decisions in any outdoor project.

Permitting Requirements
In most Oregon municipalities, fences under 6 feet tall on the rear and sides of a property do not require a permit. Front-yard fences and fences over 6 feet typically do. Rules vary by city — Salem, Wilsonville, and Oregon City each have their own ordinances. On Top Home Services verifies permit requirements before every fence project.
Installation Best Practices for Oregon
- Post depth: Posts should extend at least 1/3 of their total length below ground. In Oregon's soil conditions, 3-foot depth for a 6-foot fence is standard.
- Concrete footings: Essential in Oregon's moisture-rich soil. Posts set directly in soil will rot at the ground line within years.
- Board spacing: Leave 1/8" gaps between boards for moisture drainage and expansion/contraction.
- Cap posts: Post caps prevent water from pooling on the top of posts, which is the #1 cause of post rot.
