Regulations

Trees are Regulated


Within the City of Seattle, removing, planting, or pruning a tree is regulated depending on a number of factors . Where your tree is located – either on private property or in the right of way along a street determines which regulations you should follow. Most right of way street trees between the curb and sidewalk in residential neighborhoods are managed and cared for by the adjacent property owner.

The Seattle Department of Construction & Inspections (SDCI) administers and  regulates trees on Private Property. The Seattle Department of Transportation (SDOT) regulates trees in the street rights-of-way. 

The SDOT Tree Service Provider List shows all approved vendors who are allowed to work on street trees within the city.

The SDCI Tree Service Provider Directory is a list of all approved vendors who are allowed to work on your private trees. If you are hiring someone to care for a tree in Seattle, they must be on the Tree Service Provider registry.
