General building work permit checklist — Riverside County, California

Do you need a permit?
Riverside County requires a permit for general building work.
Riverside County publishes its own exempt-work handout (form 284-094), and it departs from the State list in several places. Accessory structures — one story, detached, 120 square feet or less — are exempt only if they have no utilities. Fences are exempt to 7 feet, matching the State. Block walls are exempt only to 3 feet measured from grade (the County equates this to 4 feet counted from footing bottom to wall top), which is tighter than the State rule. Decks track the State's four-part test: 200 square feet maximum, height staying within 30 inches of grade at every point, freestanding rather than attached, and not serving an egress door. Roof replacement is exempt only where it covers less than 25 percent of the legally existing roof area, does not involve the underlying framing, and does not recur more than once in a 12-month period. Unincorporated projects still face Riverside County Fire, septic (DEH) and, in the western county, MSHCP habitat review as separate conditions.
