Merced, CA Fire Regulations: Brush Clearance (2026)

Unlike hillside or wildland cities, the City of Merced is overwhelmingly flat Central Valley farmland and urban development, so the statewide 100-foot defensible-space requirement of California Government Code Section 51182 and Public Resources Code Section 4291 applies only where land is actually mapped in a Fire Hazard Severity Zone. On CAL FIRE's updated Local Responsibility Area maps (received by the City from the State Fire Marshal and released February 24, 2025), only a Moderate Fire Hazard Severity Zone in the northeast section of the city limits is designated - the City is required under Government Code Section 51178.5 to adopt that zone by ordinance. Most Merced parcels are not in any FHSZ and are not subject to the 100-foot rule. The practical local requirement for typical lots is weed and rubbish abatement: the City of Merced, through code enforcement and the Fire Department, can declare overgrown dry weeds, dead vegetation, and accumulated combustible rubbish a fire hazard or public nuisance and order the property owner to abate it, with the City able to clear the hazard and assess costs as a lien if the owner does not comply. Keeping grass and weeds mowed, removing dead brush, and clearing debris from around structures are the core obligations. For any parcel mapped in the northeast Moderate zone, owners should follow defensible-space best practices around structures.
