See our article on the updated Seattle Tree Protection Ordinance

Seattle’s Tree Protection Code is changing significantly with a new tree code ordinance that adds restrictions for private property owners looking to book tree care services.

This ordinance will help protect our urban canopy and work toward Seattle’s goal to reach 30% canopy cover by 2037.

We are anticipating how our clients will be impacted and preparing our team for these changes.

Decoding the Updated Tree Protection Codes

Our team of ISA Certified and Tree Risk Assessment Qualified Arborist project managers are currently analyzing the new ordinance requirements and enforcement policies, and we’ll share more information as November 10 approaches.

In the meantime, here are the biggest changes you need to know:

  • All tree care companies must be registered with the City to offer major pruning or removal of trees with a diameter at standard height (DSH) – which is measured at 4 ½ feet above the ground – larger than 6”
  • Property owners must hire a registered tree service company for major pruning and removal of trees with a DSH larger than 6”
  • Public notice of major pruning and removal of trees with a DSH larger than 6” must be posted three business days before the work begins

>Changes in the tree code will raise the standard for tree service providers in the City. To be on the City registry, companies must have at least one ISA Certified Arborist on staff, follow American National Standards Institute (ANSI) A-300 standards for tree work, have a valid and current Seattle business license, a Washington State Contractors License, and a certificate of insurance – all things Seattle Tree Care already has. Except instead of one ISA Certified Arborist on staff, we have twelve.
