Irvine FAQ
Can I work on my own car in my driveway?
Yes, occasional maintenance and repair on personally owned vehicles is permitted. The line is crossed when you accept payment, store customer vehicles, or operate as a commercial business from the property.
What about a mobile mechanic dispatched from home?
Mobile mechanics need a BAR license and a commercial business address. Dispatching paid repair work from a residential address typically violates both BAR rules and OC home-occupation zoning standards.
Santa Ana FAQ
Can I change my own oil at home?
Yes, occasional maintenance on a personal vehicle parked at the residence is allowed, provided fluids are properly contained and disposed of and no commercial activity occurs.
What about helping a friend with a brake job?
Casual help on a friend's car is generally tolerated, but charging money, advertising, or repeated activity becomes commercial repair and violates zoning and state BAR registration laws.
