Rancho Cucamonga, CA: Auto Repair on Residential Property (2026)

040 applies to any vehicle, camper, trailer, trailer coach, motorcycle, boat, or similar conveyance kept in a residential district or on any residentially occupied site citywide. Subsection (A) draws the line at commerciality, not skill level: a resident can service, repair, assemble, disassemble, wreck, modify, or restore a conveyance, but only inside a garage or accessory building, or in a paved area shielded from the street and neighboring lots by a legally built fence, wall, or equivalent screening, and the work must be noncommercial. The code calls out 'home garage repair shops' by name as the activity it is stopping: charging customers, running a side business, or repairing vehicles that are not the resident's own out of an open driveway is prohibited even with screening in place.

Subsection (B) separately bars storing or parking any disabled, unlicensed, unregistered, or inoperative conveyance, or one missing an essential legally required part, anywhere visible from the street or adjoining lots unless it too sits inside a garage, accessory building, or behind a view-obscuring fence or wall. Subsection (C) carves out a limited safety valve: a resident who owns the vehicle may perform emergency or minor repairs, or park it short-term, for up to 24 hours total within any rolling 48-hour period, without meeting the screening rules, covering a flat tire, dead battery, or quick oil change without triggering a violation. 010.
