Jurupa Valley FAQ
Does the 100-foot rule apply to my flatland Mira Loma or Glen Avon lot?
Statutory PRC §4291 defensible space mainly applies to State Responsibility Area land and Very High Fire Hazard Severity Zones — primarily the Jurupa Hills, Pedley Hills, and Santa Ana River bottom edges within Jurupa Valley. Flatter suburban lots are still subject to Riverside County Fire's annual weed abatement program for tall grass, dead vegetation, and accumulated combustibles.
When do I have to start brush clearance each year?
Riverside County Fire typically issues abatement notices in spring (April–May) ahead of fire season. CAL FIRE recommends completing defensible space work before May 1 in inland Southern California. Maintain the cleared state through the end of October.
Can I be required to clear vegetation past my property line?
PRC §4291(a)(2) allows defensible space to extend onto adjacent property only with the written consent of the adjacent owner. Otherwise you maintain only up to your property line, and that's what the law requires of you.
Riverside FAQ
How tall can weeds and grass be on my property?
Riverside enforces a fire-safe standard year-round. As a rule of thumb, dry grass and weeds should be kept under 6 inches during fire season; in FHSZ areas, vegetation must be reduced per PRC §4291 to maintain defensible space.
What happens if I don't clear my property?
After a Notice of Violation, you generally have 30 days to abate. If you don't, the city or county may hire a contractor to clear the property and bill you, with the cost becoming a lien against the parcel.
Does my parcel need 100 feet of defensible space?
Yes, if your home is within a Fire Hazard Severity Zone (Moderate, High, or Very High) under the State Fire Marshal's maps. Check the Riverside County FHSZ map or the City of Riverside Fire Department's FHSZ page.
