How to Navigate Seattle’s Tree Removal Permitting Process

How to Navigate Seattle’s Tree Removal Permitting Process

Tree removal in Seattle is not as simple as hiring a crew and cutting it down. The city has strict regulations that protect trees based on size, species, and location. Whether you plan to build, sell, or simply maintain your property, understanding how to legally remove a tree can save time, money, and potential penalties.

1. Determine if You Need a Permit for Tree Removal

  1. Not every tree requires approval to remove, but many do. Seattle classifies trees into categories or “tiers” based on their size and importance. The larger the tree, the more likely it is protected.

    To start, review the city’s Tree Regulations and identify your tree’s tier using Director’s Rule 7-2023: Designation of Tier 2 Trees.

    Generally:

    • Tier 1 trees (heritage or exceptional) are heavily protected and rarely approved for removal.
    • Tier 2 trees often require an arborist report and city review.
    • Tier 3 or 4 trees, depending on size and zoning, may not require a permit unless located in an environmentally critical area.
The city will use a variety of factors to determine a tree’s eligibility to be removed, one of which being the Diameter at Standard Height (formerly Diameter at Breast Height). This graphic shows how it is measured. (City of Woodinville)

2. Check Whether Your Property Lies in a Protected Zone

Seattle restricts tree removal in Environmentally Critical Areas (ECAs) such as steep slopes, wetlands, or shorelines. You can verify your property’s zoning and ECA status through the Seattle GIS map.

If your lot includes these areas, removal usually requires additional environmental review and a restoration plan.

3. Gather Required Documentation for Tree Removal

Most applications need the following:

  • Arborist report or tree risk assessment completed by a certified TRAQ professional
  • Site plan showing tree location, structures, and setbacks
  • Photos of the tree
  • Statement of financial responsibility
  • Replanting or restoration plan if required

All forms and details are provided through SDCI’s Tree Removal and Vegetation Restoration Application.

4. Submit Your Application Online

Applications are filed through the Seattle Services Portal. If you’re removing a tree as part of a construction or development project, the review will be connected to your building permit record.

Once submitted, the city will notify you if fees are due before approval. Keep in mind that reviews can take several weeks depending on complexity.

5. Post Public Notice Before Work Begins

Seattle requires public notice for reportable or permitted removals. You must post a sign on-site for a set number of business days before and after work. Full details are in SDCI Tip 242B: Tree Removal on Private Property.

Failure to post notice or remove a protected tree without authorization can lead to fines or mandatory restoration.

6. Work with a Qualified Tree Service or Developer

Seattle maintains a Registered Tree Service Provider Directory listing licensed professionals familiar with city permitting. Hiring a qualified arborist or working with a developer experienced in tree regulations can prevent costly mistakes and delays.
