Seattle has tree regulations that can affect whether a permit is required before removing a tree on your property. Requirements vary by tree size, species, and location, so it’s worth understanding the basics before scheduling removal.
Quick Answer
Seattle requires permits for removing trees above a certain trunk diameter, “exceptional” trees, and any removal tied to development, while hazard trees are typically handled differently but usually still need documentation. Neighboring cities like Bellevue, Shoreline, Edmonds, and Issaquah each have their own separate tree codes.
Why Seattle Regulates Tree Removal
The city’s tree protection rules are meant to preserve significant and “exceptional” trees: generally large, mature, or rare specimens that provide substantial canopy cover, habitat, and neighborhood character. Regulations can also apply to trees in environmentally critical areas, such as steep slopes or shorelines.
What Might Require a Permit
Depending on current city code, permits or notifications may be required for removing trees above a certain trunk diameter, trees classified as “exceptional,” or any tree removal connected to a development or construction project. Smaller ornamental trees and hazard trees typically have more straightforward rules, though documentation of the hazard is often required.
Hazard Trees Are Usually an Exception
Trees that pose an immediate safety hazard (dead, structurally failing, or storm-damaged) are generally handled differently than routine removals, though documentation (such as an arborist report) is often expected to support the hazard determination.
Neighboring Cities Have Their Own Rules
Bellevue, Shoreline, Edmonds, Issaquah, and other Puget Sound cities each have their own tree codes, which can differ meaningfully from Seattle’s. If your property is outside Seattle proper, it’s worth checking local requirements rather than assuming Seattle’s rules apply.

How to Avoid Costly Mistakes
Removing a protected tree without the required permit can result in fines that far exceed the cost of the removal itself. Before scheduling work on a large or potentially protected tree, it’s worth confirming requirements with the city or with a tree service familiar with local codes.
