Riverside County, CA Parking Rules: Driveway Rules (2026)

Driveway and yard parking in the unincorporated county is governed mainly by zoning Ordinance 348 and enforced by County Code Enforcement, rather than by a single dedicated section. Code Enforcement states that cars and trucks that are dismantled, wrecked or not in running condition must be stored inside a completely enclosed, permitted building such as a garage; storing them in the street, driveway or yards can require removal, and only minor repairs to one vehicle for a very short period are tolerated. Parking on unpaved surfaces is a commonly cited violation: vehicles may not be parked on a front yard, lawn or unpaved area except while the vehicle is being washed. Ordinance 348 also requires required off-street parking spaces and driveways to be developed with paved (impervious) surfaces under its parking standards. On the public side, County Ordinance 413 protects access near driveways and mail service: Section 1.10 prohibits parking any vehicle or trailer within 15 feet of a community mailbox or cluster of mailboxes serving four or more residences, and no signs are required to enforce it when parked vehicles block mail delivery. There is no county ordinance imposing a special permit just to park in your own paved driveway, but inoperable-vehicle and unpaved-surface rules apply.
