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

Weed and overgrown-vegetation control in Chino Hills operates on two tracks. First, fire-hazard weed abatement: the City's Weed Abatement program works 'under the direct supervision of Chino Valley Fire District,' and owners are 'required by the Fire District to finish cutting weeds on their property by May 15th each year.' The City states this work is 'required pursuant to the Chino Valley Independent Fire District's code' and is intended to create 'a buffer or fuel modification zone between structures and the open space.' City abatement of public open space runs from before fire season in April through July. Second, general property maintenance: the City's Code Enforcement Division responds to 'Landscaping or Property Not Maintained' and 'Vegetation/Objects Obstructing the Sidewalk/Street,' which covers overgrown yards and plant growth encroaching on the public right-of-way regardless of fire season. The City's published pages do not state a specific maximum grass or weed height in inches, so any height figure should be verified with Code Enforcement or the Fire District. These are City of Chino Hills and Chino Valley Fire District requirements, distinct from County standards.
