Tips

Summary: This Tip is an overview of a series of Tips that focus on Seattle’s tree regulations. It outlines when activities that may impact trees are allowed and how to obtain the appropriate approvals from the Seattle Department of Construction and Inspections (SDCI). Seattle’s Tree Protection Code, Seattle Municipal Code (SMC) 25.11, limits the number, size, and type of trees that may be removed from private property. These regulations help protect our urban forest.
