Full Breakdown
Riverside County Code § 15.04.080 amends Appendix J of the California Building Code so that clearing, grubbing, excavation, stockpiling, private-road paving, exploratory excavation, and precise grading all need a grading permit from the Building Official (J103.1). Minor projects, small fills under 200 cubic yards, farm discing, well excavations, and other listed cases, are exempt if approved. Unpermitted grading must be restored under Section J112, and a documented violation can trigger a five-year denial of building permits, use permits, subdivisions, and zone changes on the property (J103.5), enforced through Riverside County Ordinance No. 725. The rule applies only in the unincorporated county, not Riverside, Temecula, Palm Springs, or the county's 25 other cities.
Violations & Fines
Grading without a permit must be restored under Section J112, and documented violations can bar building, use, subdivision, and zoning applications on the property for five years under J103.5, enforced via Ordinance No. 725.
