Fontana, CA Home Business: Zoning Restrictions (2026)

Fontana Municipal Code Title 30 Zoning allows Home Occupations as an accessory use in single-family, multi-family, and planned residential districts, subject to a Home Occupation Permit issued by the Planning Division plus a citywide Business License from Finance. The defining principle is that the home remains primarily a residence; the business must be clearly secondary to the residential use. Specific standards include: the business activity must occur entirely inside the dwelling or an enclosed accessory structure (no work in the driveway, backyard, or visible from the street); no structural changes or exterior alterations that indicate a business is present; no signage other than the address; no employees who do not live at the residence reporting to the home for work; no sale of goods or services requiring customer foot traffic to the residence except by appointment; no storage of hazardous materials; no deliveries beyond normal residential parcel service. Acceptable home occupations include remote consulting, writing, accounting, online retail fulfillment with warehouse storage off-site, tutoring, and licensed professional services. Prohibited uses include auto repair, welding, large-scale catering, kennels, cannabis businesses, and any use that changes parking demand or noise. Approval requires a simple application, modest fee, and compliance confirmation. Fontana enforces violations through Code Enforcement - neighbors are common complainants when traffic, trucks, or visible activity exceed residential norms.
