Do You Need a Permit to Remove a Tree in Snohomish, WA? (2026 Guide)
Understanding tree removal permit rules in Snohomish, WA, can save you from costly fines and project delays. Whether you have a towering Douglas fir or a big-leaf maple in your yard, the City of Snohomish regulates what you can and cannot remove. Contact us today at (253) 736-5286 to get expert guidance before any tree removal work begins.
What the Snohomish Tree Ordinance Covers
Snohomish's tree rules apply to all properties within city limits. Tree removal, pruning, and maintenance must be conducted in accordance with SMC Chapter 14.120, which was updated by Ordinance 2516. This ordinance governs significant trees, protected trees, and heritage trees, each carrying different rules and replacement requirements. Even if your situation is exempt from a formal permit, you still need to follow the code.
What Is a "Significant Tree" in Snohomish?
A significant tree is the key term that determines whether you need to act before picking up a chainsaw. A tree is generally considered significant at a diameter of 10 inches or greater, while certain species like dogwoods and vine maples qualify at just 7 inches.
The city also designates protected trees and heritage trees. Snohomish maintains a Heritage Tree Program for trees of unique importance due to age, size, or historical significance, and these carry the highest level of protection. If a tree falls into any of these categories, the rules get stricter.
When Do You Need a Tree Removal Permit?
A tree removal permit is typically required before removing any significant tree. For single-family lots not subject to a pending or approved development permit, the city allows a set number of removals per year based on lot size:
- Lots under 1/4 acre: up to 2 trees per year, maximum 4 over five years.
- Lots between 1/4 and 1/2 acre: up to 4 per year, maximum 8 over five years.
- Lots between 1/2 and 1 acre: up to 6 per year, maximum 10 over five years.
- Lots between 1 and 2 acres: up to 8 per year, maximum 12 over five years.
- Lots over 2 acres: up to 10 per year, maximum 16 over five years.
Homeowners must still submit a tree removal permit application, though there is no charge. You only need to provide the tree's general location and species.
Are There Exemptions to the Permit Requirement?
Some situations do not require a permit, but most still require advance notification to the city. Exemptions do not apply to trees in critical areas or their buffers.
Common exemptions include removal of trees that do not meet the definition of significant, protected, or heritage trees, and routine landscaping such as pruning, planting, and removal of invasive or exotic species.
What About Hazard Trees?
Protected trees may not be removed unless assessed by a qualified tree professional and determined to be a hazard tree as defined in the municipal code. A written assessment from a certified arborist is typically required. If your tree is leaning dangerously or has significant decay, a professional evaluation may be the fastest route to safe, compliant tree removal.
Tree Replacement Requirements After Removal
Removing a tree does not end your obligations. Trees removed under SMC Chapter 14.120 must be replaced: significant trees require three replacements, protected trees require four, and heritage trees require five.
This replacement obligation is one of the most overlooked parts of the permit process. Understanding replacement ratios upfront helps you plan your landscape and avoid compliance issues. Illegally removing a significant tree can result in fines up to $5,000 per tree per occurrence under county authority, and city penalties under SMC 14.120 carry similar intent. This is not a risk worth taking.
City Limits vs. Unincorporated Snohomish County
Your location within or outside city limits matters. If your property sits outside the city boundary, Snohomish County's own regulations apply instead of SMC 14.120. Confirm your parcel's jurisdiction before assuming which rules govern your property.
Why Working With a Certified Arborist Helps
A certified arborist can identify your tree's classification, evaluate hazard conditions, and prepare documentation the city may require. For development-related removals, the city may require a qualified tree professional to confirm a retained tree is healthy and viable with an expected lifespan of at least 30 years. That same documentation can support hazard tree exemption requests on residential lots.
