Registered Tree Service Providers
(This web page is also known as Client Assistance Memo 2303.)

Revised January 4, 2016

Please Note: Neither the City nor this department endorses these firms or assumes liability for their services.

Info for Tree Service Providers

To be a registered tree service provider, you must submit a Tree Service Provider Registration Application to the Seattle Department of Transportation, along with a copy of:

  1. Washington State Contractor License
  2. City of Seattle Business License
  3. Certificate of Insurance, with City of Seattle listed as additional insured
  4. Current Annual Equipment permit number(s).

All firms must also agree to follow guidelines established by the Seattle Street Tree Ordinance (SMC 15.43); The Street Tree Manual, The Seattle Traffic Control Manual and the ANSI A300 Standards for tree care.

As the permittee you will be responsible for ensuring that pruning and other tree work complies with all ANSI 300 standards.  

For more information, call the City Arborist's office at 206-684-TREE (8733).

Info for Property Owners / Property Managers

Major pruning work on street trees requires the issuance of a permit. Only firms that are registered with the Seattle Department of Transportation will be issued permits for street tree work. The work they perform must be done in accordance with the City's guidelines and specifications as outlined in the Street Tree Manual.  If the firm you wish to hire is not listed below, please have them contact us, so we may assist them in obtaining the registration required to obtain a permit.

If you are planning to have work done on your planting strip trees, you, the property owner, should refer to the following Client Assistance Memos for instructions on how to care for trees that are located in the planting strip. For information on required permits, please see our website at For Planting Strip Paving and Tree Planting Rules see CAM 2304 . There are additional resources located on the City Arborist web page. Specifically go to: and

The following is a list of tree service contractors who have met the requirements for registration as a tree service provider. They also have obtained a permit authorizing operation of equipment in the right-of-way (cannot impede vehicular or pedestrian traffic, and must have insurance and take precautions to assure pedestrian safety). There is currently no fee for tree permits, but fees may be assessed if heavy equipment must be staged in the right of way, or if there is a need for a traffic control plan review. Please note: Tree Service Registration or an Annual Equipment Permit does not allow a tree service to work on street trees without first obtaining a tree pruning/removal permit from the SDOT Arborists Office.
