Fullerton, CA Home Business: Signage Rules (2026)

030(P), but the code lists ten conditions that strip the permitted-use status if broken. " The surrounding conditions show how tightly the city confines a home business: only residents living on the premises may work in it, no more than one room in the dwelling may be devoted to the occupation, no outside storage of stock in trade is allowed beyond the garage, and no equipment beyond normal household or hobby use may operate on-site. The operation cannot be evident from outside the residence through sound, odor or vibration, no new structure may be built to house it, no business vehicles may be parked on the property beyond what a residential zone otherwise allows, and clients or customers may never visit the premises.

Deliveries are limited to standard residential carriers such as UPS and Federal Express. 030(P) must be met simultaneously, a homeowner who posts even a small placard identifying the business at the curb, on a fence or in a window is out of compliance with the zoning code, not just a sign ordinance technicality. The Community and Economic Development Department administers home occupation compliance, and code enforcement staff investigate complaints from neighbors who spot advertising signage tied to a residential address.
