Street Tree Permits

If you’re thinking about planting, pruning or removing a tree in public right-of-way, you might need a permit. This page will guide you through when a permit is required, what documents you’ll need, and how to follow Seattle’s street tree regulations. Our goal is to make it easy for you to help protect and grow Seattle’s urban forest.

When do you need a Street Tree Permit? 

You’ll need a Street Tree Permit if you’re performing any of the following actions in the public right-of-way:

  • Planting a tree
  • Pruning a tree (a permit is required for Major Pruning—details below)
  • Removing or replacing a tree
  • Protecting or relocating a tree during construction

There are two types of Street Tree Permits.  Which type do you need? 

  1. For routine planting / pruning / or removing: If you would like to plant, prune, or remove a tree in public right-of-way as part of routine maintenance not associated with a development project, use the Street Trees – Plant/Prune/Remove permit. These permits are identified with a SDOTTREE prefix before the permit number.
  2. For development projects: If you are working on a development project and you would like to plant, prune, remove, relocate, or protect a tree in public right-of-way to meet code requirements, use the Street Trees – Approval for Development (Conceptual Approval) permit. These permits are identified with a SDOTTRLA prefix before the permit number.

Why are permits necessary? 

Permits help us preserve Seattle's urban tree canopy while ensuring public safety and compliance with city regulations. Street trees are an essential part of our public infrastructure, providing cleaner air, managing rainwater, and cooling our neighborhoods. When planted and cared for properly, these trees offer lasting benefits to Seattle residents, enriching our community today and for generations to come.

You’ll need a Pruning Permit in the following situations:

  • If you’re cutting branches or roots that are 2 inches or more in diameter, or
  • If your pruning will remove 15% or more of the tree’s canopy.

For minor pruning—such as trimming branches or roots smaller than 2 inches in diameter or removing less than 15% of the canopy—a permit is usually not required.
