Driveway Rules: Anza vs Riverside

Unincorporated Riverside County regulates driveways through Ordinance 457 (grading) and Ordinance 461 (road improvement standards). Driveways accessing county-maintained roads require an encroachment permit from Transportation. Width, sight distance, and drainage are controlled, and paving is required for many rural residential parcels to reduce dust and PM10 emissions.

Riverside allows parking on private residential driveways but prohibits blocking the public sidewalk. Vehicles must be parked on an approved paved surface, not on lawns or unimproved dirt. RMC Title 19 zoning standards regulate driveway width and the percentage of front yard that may be paved.
