San Benito County, CA Property Maintenance: Weeds & Overgrown Grass (2026)

Weed and vegetation control in the unincorporated county rests primarily on the public nuisance standard rather than a numeric height rule. County Code Sec. 1.06.030 declares overgrown, dead, decayed or hazardous trees and vegetation that can attract rodents, constitute a fire hazard, or be dangerous to public safety to be unlawful and a public nuisance. The County enforces a minimum weed-abatement standard and responds to fire-hazard complaints, mailing notices to abate that generally give owners about 30 days to clear hazardous vegetation before the County may abate and bill the cost. Importantly, in April 2023 the Board of Supervisors unanimously rejected a proposed amendment that would have set a maximum 3-foot weed height on parcels of 5 acres or smaller, mandated 30-foot crisscross fuel breaks, and imposed 15-foot fuel breaks on pasture and crop land, after residents objected to the cost and environmental burden. So no specific weed height, fuel-break width or distance is codified county-wide; do not assume a 3-foot rule applies. Separately, parcels in the State Responsibility Area must comply with California Public Resources Code Section 4291, which requires 100 feet of defensible space around structures (enforced through CAL FIRE). Residents are advised to mow or weed-eat flammable vegetation, especially on slopes, to maintain that 100-foot defensible space.
