Pleasanton, CA Property Maintenance: Weeds & Overgrown Grass (2026)

The City of Pleasanton sets a specific weed/grass standard in Chapter 9.28 of its Municipal Code. All premises and exterior property must be maintained free from weeds or uncontrolled plant growth in excess of 20 inches in height, and all noxious weeds are prohibited on developed properties. The code defines 'weeds' as all grasses, annual plants and vegetation other than trees or shrubs, but expressly excludes cultivated flowers and gardens. The code also identifies as nuisances: dead, decayed, diseased or hazardous trees, weeds or other vegetation that are unsightly, dangerous to public safety, and visible from a public street; and overgrown vegetation visible from a public street that is likely to harbor rats, vermin or other nuisances, that obstructs the view of drivers on public streets or driveways, or that impedes pedestrian or other lawful travel on sidewalks, walkways or other public rights-of-way. On developed properties, overgrown weeds and vegetation are enforced by the city's Code Enforcement Division. On undeveloped/vacant land, hazardous vegetation is instead handled by the Livermore-Pleasanton Fire Department. Upon failure of the owner to cut and destroy weeds after a notice of violation, the owner is subject to prosecution as prescribed by the authority having jurisdiction. Cultivated lawns, flowers and gardens are not 'weeds' and are not restricted by the height standard.
