Grass Height Limits
Beaverton Code Chapter 5 (Public Nuisances) defines noxious vegetation to include grass exceeding 10 inches in height and weeds going to seed. Property owners must keep their lot and the abutting public right-of-way (the planting strip between sidewalk and curb) free of noxious vegetation. After notice, the City may abate the nuisance by mowing and charge the cost back to the property, with the unpaid charges becoming a lien on the property.

Some RestrictionsTree Trimming
Beaverton regulates tree trimming and removal under the Beaverton Development Code Chapter 60.60 (Trees and Vegetation), which protects designated Significant Trees, Significant Tree Groves, and Historic Trees. Routine pruning of small private trees is allowed without a permit, but pruning, topping, or removing a Significant Tree or any street tree in the public right-of-way requires city approval through Beaverton Planning. Property owners are responsible for keeping trees clear of sidewalks, streets, and intersection sight lines.

Some RestrictionsWater Restrictions
Beaverton residents are served by either the Tualatin Valley Water District (TVWD) or the City of Beaverton Water Department depending on location, with some areas receiving wholesale water from the Portland Water Bureau or the Joint Water Commission. Both TVWD and the city follow the Regional Water Providers Consortium curtailment framework (four stages from voluntary conservation to mandatory outdoor watering bans). Mandatory restrictions are not in effect year-round and are triggered by drought conditions or supply constraints; year-round conservation practices (efficient irrigation, leak repair) are always encouraged.
