Whittier, CA Landscaping Rules: Grass Height Limits (2026)

Whittier is an incorporated city, so overgrown-vegetation rules come from the City of Whittier's own code, not Los Angeles County. The City regulates tall grass and weeds through a nuisance and fire-hazard standard rather than a fixed height. Whittier Municipal Code Section 8.24.010 (Unsafe conditions) states that no owner, agent, or person in control of any lot may maintain or allow the premises to be maintained in a condition in which weeds, rubbish, or any materials exist that constitute a fire hazard, may provide a refuge for rats or other vermin, or may produce pollen injurious to health; the existence of any such condition is declared to be a public nuisance. Section 8.24.007 puts the duty to remove such weeds and rubbish on the property owner, including adjacent rights-of-way. There is no published grass-height number such as the 6-inch or 12-inch limits some cities use. Because Whittier sits at the edge of the Puente Hills, parts of the city are in a CAL FIRE Fire Hazard Severity Zone (Local Responsibility Area), and the State Fire Marshal released updated Very High / High / Moderate hazard maps for Whittier on March 24, 2025, which raises the fire-hazard concern behind weed and brush clearance. Enforcement runs through the director of public works under the Chapter 8.24 notice-and-abatement process described in Whittier's weed-ordinance pages.
