Tree removal permit rules in Tualatin, OR — sometimes called heritage tree, protected tree, or street tree ordinances — list which trees require a permit before you can cut them down.
Tualatin Development Code Chapter 33 regulates removal of any tree eight inches or larger in diameter (measured 4 feet above grade) on private property. Homeowners may remove up to four qualifying trees per calendar year without a permit, but heritage trees and site-plan trees always require review.
Tree removal on private property is regulated by Chapter 33 of the Tualatin Development Code (TDC). A regulated tree is any living standing tree with a trunk at least 8 inches in diameter measured 4 feet above ground. A property owner may remove up to four regulated trees per calendar year without a permit; the fifth tree in the same year requires a Tree Removal Permit. Heritage Trees and trees preserved under an approved site plan always require separate review. Where the site has an approved site plan, removal of up to 10 protected trees requires a Minor Architectural Review, and 11 or more requires a full Architectural Review. Trees in wetlands or vegetated corridors trigger Clean Water Services review.
Removing five or more regulated trees in a year without a permit, removing a Heritage Tree, or cutting a site-plan tree without architectural review violates TDC Chapter 33. Planning may issue stop-work orders, civil penalties, and require replacement plantings.
