Permits Required for Tree Removal or Replanting in Cities Around Oregon and Washington

Every city has varying requirements for how its trees are planted, removed, and pruned. And removal of trees above a certain size needs to be handled by a certified arborist.

Depending on size, age, and location, residents may or may not need a permit. We’ve put together a guide for cities around SW Washington and NW Oregon to help you learn more about regulations in your area. The information below generally applies to residential areas. Commercial permitting and fees vary.

Tree permits are required “whenever pruning or removal of a street tree is necessary. A street tree is any tree located within the public right-of-way.

Street Tree Permits are not required for pruning or removal of trees on developed private property.
