This Tree Service Provider Directory is a list of providers who have met the registration requirements for the Seattle Department of Construction & Inspections (SDCI) registry for tree work on private property*, for the Seattle Department of Transportation’s (SDOT) registry for tree work in the public right-of-way**, or both.

*For work on private property (SDCI Tree Service Providers), please note that only tree service providers with a current Tree Risk Assessment Qualification (TRAQ) may prepare tree risk assessments for hazardous tree removal.  Contact a provider from the list below to find out if they offer TRAQ services.

**For work in the public right of way (SDOT Tree Service Providers), please note that there is currently no fee for tree permits, but Right of Way Use Permit fees may apply if heavy equipment must be staged in the right of way, or if there is a need for a traffic control plan review.  Work on street trees requires a tree pruning/removal permit from SDOT Urban Forestry in addition to any Tree Service Provider registrations or an Annual Equipment Permits.

This directory only provides information about a tree service provider’s registration status.  The City, SDCI and SDOT do not endorse the listed firms or assume liability for their services.
