Beaverton, OR Landscaping Rules: Tree Trimming (2026)

Beaverton's tree regulations live in the Beaverton Development Code (BDC) Chapter 60.60 (Trees and Vegetation), which establishes the city's urban-forestry framework. The code distinguishes between routine private trees, designated Significant Trees and Significant Tree Groves, Historic Trees, and street trees in the public right-of-way. Routine pruning of small or non-designated trees on private property is generally allowed without a city permit, provided the work does not constitute removal and does not damage long-term tree health. Significant Trees and Significant Tree Groves identified during development review or formally designated under BDC Chapter 60.60 are protected: removal, topping, or substantial pruning that compromises canopy or structural integrity requires city review and approval, and tree replacement or mitigation may be required if removal is approved. Street trees, typically located in the planting strip between the sidewalk and the curb, are part of the public right-of-way and may not be pruned beyond minor clearance pruning or removed without coordination with the city. Adjacent property owners are responsible for keeping street trees clear of sidewalks (7-foot pedestrian clearance), streets (typically 14-foot vehicle clearance), and intersection sight lines. The Beaverton Planning Division administers Significant Tree and street-tree decisions, and the city maintains an online tree-information page.
