What is a Street Trees Versus Private Tree?

These types of trees are regulated with differing codes and standards, so it is important to start by understanding the difference.

  • Street Trees

Any tree that is growing in the City's public area near the street, called the right-of-way (ROW) is a Street Tree.

Example of Street Trees
  • Care and maintenance of Street Trees in the right-of-way is the responsibility of the adjacent (or bordering) property owner. 
  • The right-of-way can be with or without a sidewalk, the trees below are still street trees.
    • More Terms: An "unimproved" right-of-way does not have a sidewalk, as opposed to an "improved" one.

  • The configuration of theright-of-way sizing variesdepending on the location, so it is necessary to look up the address and check (more details below for looking up your address).
    • Note: A tree that straddles the line between private property and the right-of-way is considered a Street Tree. 

Examples of various right-of-way configurations:

Right of way line beyond the sidewalk example

The right-of-way line extending past sidewalk and towards a private property. The trees within this right-of-way are Street Trees.

Example of a right-of-way with no planting strip, but with a 4 -foot wide right-of-way (ROW) between the sidewalk and the private property boundary. The tree pictured is a Street Tree.

  • Private Trees

A Private Tree is a tree located on private property, that does not straddle the right-of-way line. 

Example of Private Tree

Overlay Zone or Plan District

In certain environmental overlay zones and plan districts, private property trees of any size may require a permit for removal. 


Gathering Information 

Using PortlandMaps.com to Determine if a Tree Is a Street or Private Tree

Portlandmaps.comis a useful resource for seeing aerial photos and clear private property lines. 

Many Street Trees are in the planting strip between the sidewalk and the curb. Most trees within 15 feet of the edge of the roadway (paved or unpaved) are Street Trees. See the definition of a Street Tree in the Title 11 Tree Code under Chapter 11.80.020.B.36.K.

To determine if a tree in an alleyway or unimproved street is a Street Tree:

Finding aerial Icon
Click plane icon to show aerial view of address
  1. Go to PortlandMaps.com.
  2. Type in the address or navigate to your location on the map.
  3. Click on the airplane icon at the top to turn on the aerial photo view.
  4. Determine if the tree is inside or outside of the blue outline. If it is inside the line, then it is a private property tree. Remember, if it straddles the line, it is likely considered a Street Tree. 

Determine if a Land Use Review Governs Tree Preservation

Important Definitions

It is important to understand if you must include tree permitting into a larger project (Development) or if this is a stand alone permit (Non-development). The permitting process for developments varies from non-development, it is best to head that way now. 

Development Versus Non-Development Permits 

  • Development (or Redevelopment) Permits

    • Involve new construction, additions, and exterior renovations. 

      • Examples: Building a new house, or adding/altering an existing building. 
        • This process requires submitting plans and going through a review process. 
        • The tree plans are reviewed with this submittal. 
        • Tree work is permitted through this process, not by individual tree. 

Follow Trees and Development link if your tree work is part of a development. 

  • Non-development Permits

    • Are permits not related to any development. 

      • Multiple trees can be permitted through this process
      • Examples:
        • A Street Tree needs a limb pruned.  
        • A large private tree is dead, or dying and needs to be removed. 
    • Below we expand on these types of permits:
