Many municipalities within the Portland Metro area require tree permits for tree care, tree removal, and urban tree planning. As a homeowner, it is important that you check with your local jurisdiction to determine if the tree care you request requires tree permits prior to commencing the work. Such permitting can be based on the location of the tree, the neighborhood, if a Homeowner Association (HOA) exisits and if your property falls within other environmental zones. Always confirm the requirements for your home. This resource page is meant to assist homeowners with locating the appropriate websites to obtain the needed information and phone numbers for contact.

  • A permit is always required for work on trees in the right-of-way.  Whether or not the tree can be removed follows another process.  Our code requires that trees in the right-of-way be dead, dying, or diseased before they can be removed.  If it is clear that the tree is dead, engineering can allow the tree to be removed and replaced.  If the tree’s health is in question, an Arborist Report is required to make the determination.  If the tree is on private property generally there is no permit required.  However, there are overlays in the city (Willamette Greenway, wetland conservation, etc.) that have different rules, even on private property.  A quick call to engineering will let you know if the property in question is in one of these areas.
