Simi Valley Driveway Rules Rules (2026): What You Need to Know

Simi Valley Municipal Code Title 4, Chapter 9 and the Development Code Title 9 collectively regulate how and where vehicles may be parked on private residential property. All vehicle parking must occur on a solid paved surface such as concrete or asphalt — parking on grass, dirt, or landscaped areas is prohibited. Driveways may not be extended informally; any expansion of paved parking area on a residential lot requires a building permit and must be constructed to city standards. A parked vehicle on a driveway may not overhang the public sidewalk or block the pedestrian right-of-way, which would create an accessibility and safety hazard.

The Simi Valley Municipal Code and California Vehicle Code provisions enforced locally prohibit storing inoperable, dismantled, or unregistered vehicles in open view on residential property. Vehicles that are not currently registered with the DMV, have expired tags, or are in a state of disassembly (missing wheels, engine exposed, covered with a tarp for an extended period) may be subject to abatement as a nuisance. Residents are required to store such vehicles in an enclosed garage or behind a solid fence not visible from public view. Covered storage with a tarp visible from the street generally does not satisfy the screening requirement.

Garages must retain their functionality as vehicle parking spaces per the zoning code. Conversion of an attached garage to a bedroom, game room, or workshop without pulling the appropriate permit and providing equivalent replacement parking is a code violation. Permitted accessory dwelling unit conversions of garages are allowed under state ADU law but require eliminating the parking space consistent with applicable exemptions.
