- Defensible space rules
- Source
Defensible space in Mariposa County is governed by state law. Under PRC 4291, homeowners in the State Responsibility Area must keep 100 feet of defensible space around their home, or clear to the property line if it is closer, with the most intensive fuel reduction nearest the house. CAL FIRE's Madera-Mariposa-Merced Unit checks compliance with seasonal defensible space inspectors and engine crews (LE-100 inspections) and completed 7,812 inspections across Madera, Mariposa and Merced counties in 2025, focusing on areas never inspected or not inspected in over two years. For new construction, the unit's fire marshal, acting as County Fire Warden, applies the PRC 4290 fire safe standards with county building and public works staff.
- Chipping
- Source
The Mariposa Fire Safe Council's Brush & Chip Program chips brush from the 100-foot defensible space and driveway of inhabited homes for Mariposa County residents, and also brushes defensible space for low-income (PG&E CARE-qualified) or disabled residents. As of September 2026 the council lists the program as on hold until further notice for environmental study updates. When it runs, piles must be within 10 feet of a truck-accessible driveway (not on a county road), limbs 6 inches or less in diameter, piles no more than 4 feet high and free of trash.
