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

In unincorporated Yuba County, overgrown weeds and dry vegetation are addressed under the Property Maintenance Ordinance, Chapter 7.36. Section 7.36.310 makes it a public nuisance to maintain or use property in violation of the County Code, State law, or Federal law, and to allow conditions that significantly hamper the prevention or suppression of fire. This expressly ties into California Government Code Sec. 39500 et seq. and Sec. 39560 et seq., the State weed and rubbish abatement laws that empower local agencies to declare weeds and combustible rubbish a public nuisance and order their removal. Research of the County Code and County Code Enforcement materials did not reveal a specific numeric grass or weed height threshold (for example, a published maximum height in inches) for unincorporated parcels — the standard is whether the vegetation constitutes a fire, health, or safety hazard or a nuisance, rather than a fixed measurement. Separately, the County Agricultural Commissioner runs a grant-funded roadside weed-spraying program targeting invasive species such as skeletonweed to reduce fire hazard and protect rangeland and ecosystems; that program is about County roadways and invasive plants, not a parcel-by-parcel grass-height rule for homeowners. Property owners with hazardous weed or brush growth can be served a Notice and Order to Abate under Chapter 7.36 and, if they fail to clear the hazard, the County may abate it and lien the costs.
