Summary
Parcels in San Joaquin County within State Responsibility Areas (SRA) or mapped Fire Hazard Severity Zones must maintain 100 feet of defensible space per California PRC §4291. The eastern foothills (Clements, Linden, Lockeford area) contain SRA land inspected by CAL FIRE. Weed abatement on valley-floor parcels is handled by county Code Enforcement under Government Code §39560.
Maintain defensible space of 100 feet from each side and from the front and rear of the structure, but not beyond the property line, except as provided in subparagraph (B). The amount of fuel modification necessary shall consider the flammability of the structure as affected by building material, building standards, location, and type of vegetation. Fuels shall be maintained and spaced in a condition so that a wildfire would be unlikely to ignite the structure. This subparagraph does not apply to single specimens of trees or other vegetation that are well-pruned and maintained so as to effectively manage fuels and not form a means of rapidly
Full Breakdown
California Public Resources Code §4291 requires 100 feet of defensible space around structures in State Responsibility Areas and Very High Fire Hazard Severity Zones. In San Joaquin County this primarily affects the eastern foothill edge around Clements, Lockeford, and the upper Calaveras River watershed. Zone 1 (0–30 feet from the structure) must be lean, clean, and green: remove dead plants, trim tree limbs to 10 feet above chimneys, keep roofs and gutters clear. Zone 2 (30–100 feet) requires reduced fuel: horizontal and vertical plant spacing, grass cut to 4 inches, dead material removed.
CAL FIRE conducts annual inspections in SRA areas. On the valley floor, most land is Local Responsibility Area, the County Weed Abatement Program (administered by Code Enforcement under Government Code §§39560–39588 and Health & Safety Code §14875) mandates clearing of weeds and combustibles on parcels that pose a nuisance or fire hazard, with annual notices typically sent in April before the summer fire season. SJVAPCD burn permits are required before any vegetation burning and are often suspended entirely during no-burn days.
Violations & Fines
PRC §4291 non-compliance: first notice to abate, then fines up to $500 per day until corrected (Public Resources Code §4291(h)). County weed abatement: forced abatement by contractor, cost assessed against property as a lien plus 25% admin fee.
