San Jose FAQ
Can I work on my own car in my driveway?
Yes, occasional repair of personally owned vehicles is allowed. The ban is on operating a business: accepting payment, advertising services, repairing customer vehicles, or storing client cars at a residence.
What if I only work in the garage with the door closed?
It still violates Title 20 if customers, payment, advertising, parts deliveries, or commercial fluid disposal are involved. The standard is whether the activity is a commercial business, not whether neighbors can see it.
Santa Clara FAQ
Can I fix my own car in my driveway?
Personal vehicle maintenance is allowed but should occur inside a closed garage. Driveway oil changes risk stormwater violations, and major repair noise can violate quiet hours.
Can I run a side mobile mechanic business from home?
Not as a home occupation. Customer vehicles, advertising, paid auto repair, and outdoor painting are prohibited in residential zones under Title C zoning rules.
