Tree protection and removal requirements vary based on the tree tier, zone, lot condition, and whether development is proposed. Removal of Tier 1, Tier 2, Tier 3, or Tier 4 trees is generally prohibited in all zones when no development is proposed either on developed property or undeveloped land. While tree removal is generally prohibited when no development is proposed, tree protection regulations have several exemptions and allowances for tree removal outside of development proposals. Most of these removals require SDCI review and approval prior to the tree work. See Tip 242B, Tree Removal on Private Property, for information on tree removal allowances and fees associated with SDCI review. Trees less than 6 inches DSH are not regulated by SMC 25.11. If you have questions, please contact us via email at sdci-trees@seattle.gov or through SDCI’s Submit a Request form.
If you need to remove a tree on your property, follow these steps to get approval from the Seattle Department of Construction and Inspection.
