Chino Hills, CA Property Maintenance: Vacant Lot Maintenance (2026)

The City of Chino Hills sits in a wildland-urban interface, so vacant and undeveloped lots are primarily regulated through fire-hazard weed abatement rather than a standalone vacant-property ordinance. The City's Weed Abatement program 'works under the direct supervision of Chino Valley Fire District,' and the City states the work is 'required pursuant to the Chino Valley Independent Fire District's code.' Property owners are 'required by the Fire District to finish cutting weeds on their property by May 15th each year.' The City's own crews abate weeds on public open space, creating 'a buffer or fuel modification zone between structures and the open space,' with city work beginning before fire season in April and continuing through July. Beyond fire-hazard vegetation, vacant lots are also subject to the City's general nuisance and property-maintenance authority under Title 8 of the Municipal Code, which Code Enforcement uses to address illegally dumped debris and other blight on undeveloped parcels. Owners of vacant Chino Hills lots should keep them cleared of dry brush and weeds by the May 15 Fire District deadline and free of accumulated trash. These are City/Fire District requirements distinct from San Bernardino County rules.
