Street Tree Attachment Permits

When is a permit required?

  • Street trees: A permit is required for permanently attaching items to street trees, which are trees in the public right-of-way (typically located between the sidewalk and the curb). "Permanently" is defined as 6 or more continuous months in a 12-month period. 
  • Private trees: No permit is required for attaching items to private property trees.

Application and instructions

Only an owner of the property abutting the planting strip, the property owner's designee, or a neighborhood business association may apply for a street tree attachment permit.

There is a non-refundable fee of $264 for a street tree attachment permit application. The application can include trees at multiple addresses. The check should be addressed to City of Portland. Payment by cash, debit or credit card is also accepted when the application is dropped off in person at the Development Services Center
