Modesto, CA Business Licensing & Operations: Auto Repair on Residential Property (2026)

207(a). Unlike the traffic, signage, and staffing conditions that a home business can satisfy to operate legally, vehicle repair is disqualified outright regardless of scale, meaning even an occasional side job fixing a neighbor's car for pay falls outside the permitted home occupation category. 104(d), which governs licensed auto repair shops generally: the business of auto repair shall only be conducted at a location approved by the Planning Department and shall not be operated as a mobile business that goes house to house or building to building.

104(d). 104(a)-(c) adds further street-use restrictions applicable to any licensed auto repair shop, barring repair work, storage, or display of vehicles being serviced on any public street or highway, with a narrow exception for the shop operator's own registered vehicle. Because these are treated as zoning and licensing conditions rather than mere guidelines, operating an unlicensed at-home repair business or running a repair operation as a mobile service exposes the operator to the same infraction enforcement Modesto applies to other home occupation and public-street violations.
