Rancho Cucamonga requires a home occupation permit for any business conducted from a residence. The business must be incidental to residential use with no customer traffic, signage, or outward evidence.
Rancho Cucamonga Municipal Code Title 17 (Zoning Code) regulates home-based businesses through a home occupation permit administered by the Planning Division. The business must be clearly incidental and secondary to the residential use, conducted entirely within the dwelling or an accessory structure by residents of the household. Standards typically include no more than one non-resident employee, no outdoor storage or display of materials, no signage visible from the public right-of-way, no customer or client visits that generate additional vehicle trips, and no equipment that creates noise, vibration, smoke, dust, odors, heat, glare, or electrical interference perceptible beyond the property line. Businesses involving hazardous materials, vehicle repair, manufacturing, or retail walk-in sales are generally prohibited. A business license from the Finance Department is also required. Apply through the Planning Division at City Hall or call 909-477-2750 for specific standards.
