Whether you are maintaining a mature yard, prepping a rental, or planning a remodel, Kirkland’s tree rules affect your timeline and budget. Knowing when you can prune, when you need a permit, and how mitigation works helps you avoid fines and keep projects moving.
Why Tree Rules Matter in Kirkland
Kirkland treats trees as vital infrastructure. The City aims to protect canopy, manage risk, and guide growth through its tree code and permit system. If you own in Kirkland, understanding the basics protects property value and reduces surprises during maintenance or construction.
Kirkland regulates most trees at or above 6 inches DBH and sets extra protections for landmark trees at 26 inches DBH or more. The City’s policy goals balance a healthy urban forest with practical development and safety needs according to the City’s tree guidance.
Pruning Standards And Permit Triggers
Healthy pruning is part of routine care. But some actions cross into regulated work that can be treated like removal.
Allowed Routine Maintenance
- Selective pruning that maintains structure and health
- Removal of dead, diseased, or broken branches using proper cuts
- Light crown cleaning and clearance pruning away from your home
On private property, routine pruning is commonly allowed without a permit unless the tree is in a critical area or buffer, the Holmes Point Overlay, a shoreline setback, or protected by covenant or NGPE. Topping is prohibited, and excessive pruning can be considered removal per City guidance.
For public trees in the right of way or parks, you generally need City approval. Limited “minor pruning” of small branches may be allowed, but you must follow City limits and definitions. When in doubt, contact the City before any work on public trees as outlined by the City.
Work That Needs Approval
You should expect City review when any of the following apply:
- Pruning that removes a significant portion of live canopy, which can be treated as removal
- Any work in mapped critical areas or buffers, Holmes Point Overlay, or shoreline setbacks
- Work on public right of way or park trees
- Removal of regulated or landmark trees
The Kirkland Zoning Code Chapter 95 sets definitions, thresholds, and replacement standards for removals and mitigation see KZC 95.
Documenting Tree Condition
Good records can save time and prevent disputes:
- Take clear before-and-after photos
- Note dates, locations, and measurements such as DBH
- Keep invoices and credentials for arborists
- If risk is a concern, obtain an arborist assessment in writing
If questions arise, this file demonstrates intent and compliance the City encourages documentation on its Trees page.
Tree Permits: Process, Timelines, Fees
Kirkland uses a notification or permit system for removals and some pruning, with online submission and City arborist review.
When You Need A Permit
Common triggers include:
- Removing a regulated tree on private property
- Removing or heavily pruning trees in critical areas or overlays
- Any work on right-of-way or park trees
- Landmark tree removal requests
Some private-property removals may qualify for a simpler notification pathway if allowances and retention minimums are met. Otherwise, a full permit is required. The City explains when notification is allowed and when a permit is necessary on its Trees page see City guidance.
How To Apply Step By Step
- Define scope: identify trees by location and DBH; check if you are in a critical area or overlay.
- Consult an arborist: many applications require an arborist report and a mitigation plan.
- Prepare documents: site plan, photos, tree list, and any replanting details per KZC 95 see KZC 95.
- Submit online: use the City’s MyBuildingPermit.com portal linked from the Trees page.
- Respond to review comments: the Development Review Arborist may request revisions.
- Receive conditions: permits often include protection measures and replanting terms.
- Schedule inspections as required and keep approval on site during work.
The City aims to issue determinations within a defined review window after a complete submittal per the Trees page.
Typical Fees And Mitigation
Budget for application and review fees, and plan for mitigation. Most removals require replanting based on the size and type of tree removed, or a fee-in-lieu payment if allowed by code. Replacement ratios and maintenance obligations are established in KZC 95, and the City records mitigation agreements for long-term compliance see KZC 95 standards and City fee framework.
After Approval And Inspections
- Follow tree protection and work-hour conditions
- Post the permit on site if required
- Complete replanting within the deadline set by your permit
- Keep records for final inspection and long-term maintenance
Unauthorized work can trigger enforcement and delays see Code Enforcement.
Special Cases And Exceptions
Some situations carry unique rules or faster paths.
Emergency And Hazard Trees
If a tree poses an imminent risk to life or property, the City allows emergency removal without prior approval. You must report the removal within the required timeframe and provide evidence such as photos or an arborist letter. If the City determines the emergency was not justified, fines can apply per City guidance.
Right‑Of‑Way And Utilities
Trees in the public right of way or parks require City permits. If you are unsure whether a tree is on your property or in the right of way, check City maps or call the Planning and Building Department for direction. Do not prune or remove public trees without authorization as the City advises.
Renovations, Additions, And New Builds
Construction projects are reviewed under KZC 95, which sets minimum tree retention, protection, and replacement standards. Removing healthy regulated trees just before applying for development permits can trigger waiting periods and complicate approvals. Plan your tree strategy early in design and coordinate with your builder and arborist see KZC 95 and City guidance.
HOAs And Neighborhood Standards
City approval does not override HOA rules. Review your CC&Rs and architectural guidelines for any extra restrictions or approvals. Aligning both City and HOA requirements avoids double violations and rework.
Compliance Tips And Professional Help
A proactive process saves time and protects value.
Avoiding Fines And Delays
- Check rules before work begins, especially in overlays and near shorelines
- Confirm your scope in writing and keep a photo log n- Build review time into your schedule, including potential revisions

Choosing Qualified Arborists
- Look for ISA Certified Arborists with local permitting experience
