Parks and Public Spaces Washington 4 Minutes Read ยท published February 07, 2026 Flag of Washington

Seattle, Washington property owners and managers should follow city rules for pruning trees in rights-of-way, street trees, and regulated trees on private property. This guide explains the typical pruning schedule, when a permit or notice is required, who enforces the rules, and practical steps to apply, report, or appeal. It consolidates official Seattle sources and directs you to the permitting pages and municipal code for authoritative procedures and contact points.

When to Prune

Seattle recommends timing that minimizes stress to trees and protects nesting birds during local nesting seasons; specific timing windows can vary by species and location. For most routine maintenance of privately owned trees, pruning outside of bird-nesting season is ideal when possible. For street trees or trees that affect sidewalks, utilities, or public safety, coordinate with the city before work begins. [1]

  • Time: avoid major pruning during bird nesting (spring) when possible.
  • Safety: remove dead or hazardous limbs immediately when they present a public danger.
  • Coordination: contact the city before pruning street trees or trees adjacent to sidewalks.
Contact the city before pruning trees that overhang sidewalks or streets.

Permits and When They Are Required

Permits depend on tree location and type. Street trees in the public right-of-way generally require coordination or a permit through the city department that manages trees in the right-of-way. On private property, substantial pruning, cutting of regulated trees, or work related to development may trigger separate permits or tree protection requirements. For official permit details and application steps, consult the city tree and permit pages. [1]

  • Street-tree pruning: check SDOT permit requirements before work on public trees.
  • Private property: development-related tree work may fall under building or land-use permits.
  • Questions: contact the listed department for site-specific guidance.
Permits or approvals are commonly required for work on street trees and for substantial alterations to regulated trees.
