Our Seattle Municipal Code (SMC) 25.11, Tree Protection, limits the number, size, and type of trees that may be removed from your property. We regulate the removal of trees because they are important for human and environmental health.
See our Trees & Codes webpage for more information on tree requirements on private property, tree service providers, tree public notice, and additional resources.
Our tree protection requirements vary based on the size (tree tier), species, whether there is construction occurring or proposed on the lot, and the zoning of the property. Certain trees are protected and may not be removed unless specific requirements are met. If you unlawfully remove a tree, the penalties can be expensive. If you are planning a construction project and your site contains large trees, please contact SDCI early to understand the protection requirements or opportunities for removal if certain conditions exist on your lot.
There are a series of Tips related to Seattle’s tree regulations that provide more detailed information and guidance about specific regulations for property owners and tree service providers. So far these include:
In addition, you should also be familiar with any associated Director’s Rules that support the Tree codes. So far these include:
The fee for tree removal varies depending on the type of request, summarized below. The fee is charged when you apply.

Use the resources below to determine if you need a permit or SDCI approval before removing your tree.

If necessary, we can set up a virtual meeting to discuss potential or actual projects.

Start your application. Tree removal associated with a construction project is typically reviewed through the SDCI record authorizing the construction. When SDCI review and approval is required to remove a tree outside of development, you can request approval using the Tree Removal and Vegetation Restoration application through the Seattle Services Portal. Either login to your existing account or create a new account if necessary. Instructions for submitting this application are at: How to Apply for SDCI Approval for Tree Removal and Vegetation Restoration.
