Seattle Tree Service Providers: New Single Registration for SDCI and SDOT

February 28, 2024

Hiring tree service providers knowledgeable in the City’s regulations ensures that your provider knows and understands the City’s regulations and policies for proper tree care and protection. Tree service providers are required to be registered with the City to do certain tree work on private property (registry administered by the Seattle Department of Construction and Inspections (SDCI)) and in the public rights-of-way (registry administered by the Seattle Department of Transportation (SDOT)). These two departments previously managed separate application and monitoring processes for their respective tree service provider registries. We are happy to announce that the City of Seattle launched a single registration process for SDCI and SDOT Tree Service Providers on February 22, 2024. The new registration process helps create a more streamlined and efficient experience for tree service providers and a more automated and efficient process for staff.

New Tree Protection Code

August 1, 2023

The City of Seattle is committed to protecting our urban tree canopy. Canopy cover is one important measure of the health of the urban forest. Urban trees provide numerous ecological, economic, and social benefits, including wildlife habitat, neighborhood livability, and improved public health outcomes. The Seattle City Council recently passed Council Bill 120534 establishing new tree protection requirements on private property in Seattle. The new regulations went into effect on July 30, 2023. It is important for property owners, tenants, developers, and tree service providers to understand the new regulations to know when a tree is protected and when a tree may be removed. We are currently developing public information to help explain the new regulations. Please watch for updates on our Trees & Codes website, including links to any new or revised Tips and Director’s Rules.

New Tree Protection Ordinance Goes into Effect on July 30

July 27, 2023

Beginning July 30, Seattle’s new tree protection ordinance will take effect for all trees on private property. The new tree code (Ordinance 126821) strikes a balance by protecting and growing a healthy tree canopy citywide and addressing inequities in tree canopy distribution that impact historically underserved communities while supporting housing production needed during a homelessness and housing crisis.  As shown in the Office of Sustainability and Environment’s 2021 Tree Canopy Assessment, most tree loss is occurring outside of development and in areas zoned Neighborhood Residential (formerly Single Family) and Parks and Natural Areas. Losses in these two areas account for 78% of the total canopy loss between 2016 and 2021. The assessment also showed the canopy loss is not happening equitably, with neighborhoods most impacted by racial and economic injustices starting with less canopy coverage and losing more canopy than the citywide average.  Under the new ordinance, the City will add tree protections for over 157,000 more trees by limiting removal of trees on properties not undergoing redevelopment and requiring replacement for any tree removed that is 12” or greater in diameter. Removal of hazardous trees will also require tree replacement, and there are new incentives for property owners and builders to retain trees.

Updates to Seattle Tree Service Provider Regulations

April 3, 2023

In April, 2022 the City of Seattle passed regulations to help protect our urban canopy. Those regulations require tree service providers to register with the City of Seattle before conducting commercial tree work, consultations on private property and posting a public notice on-site for any tree work beyond minimal routine maintenance. In February 2023, the City passed additional legislation to modify and clarify those regulations. See the SDCI tree code webpage for the detailed registration and notice requirements.
