Summary

Removing a tree in Woodinville can require a permit depending on its size, location, and whether it falls under the city’s “significant tree” protections. Homeowners generally do not need a permit for dead, hazardous, or smaller trees, but removals in critical areas or newer developments often require approval. This guide breaks down the updated 2025 regulations so you can make informed decisions and avoid fines.

Do I Need a Permit to Remove a Tree in Woodinville? (2025 Update)

Tree removal regulations in Woodinville can be complex, and requirements vary based on tree size, location, and property zoning. This guide provides a straightforward overview of when a permit is required and when it is not, based on the most current 2025 city guidelines.


When a Permit Is Not Required

A removal permit is typically not required when the tree:

• is dead, dying, or poses an immediate hazard
• is under 6 inches in trunk diameter (measured at 4.5 feet above ground)
• is not located in a designated environmentally critical area
• is not a “significant tree” under Woodinville Municipal Code
• is not protected under a subdivision or HOA tree retention plan

Hazardous trees can often be removed immediately for safety reasons, with documentation provided afterward if necessary.


When a Permit Is Required

A permit is usually needed if the tree:

• has a trunk diameter of 12 inches or greater
• is located within a wetland, buffer, steep slope, or other critical area
• is listed as a “significant tree” based on species and size
• is part of a required landscape or retention plan
• is within a newer development with protected plantings

If you are unsure, an arborist can quickly determine whether your tree meets the city’s criteria.


What Is a “Significant Tree”?

Woodinville designates certain trees as “significant” based on:

• species
• trunk diameter
• ecological value
• contribution to the local canopy

Some species receive special protection due to their importance to the region.


Emergency Removals

If a tree poses an immediate safety risk, emergency removal is permitted. Homeowners should document the condition—such as photos of cracks, uprooting, or leaning—and notify the city afterward if required.
