Santa Paula, CA Home Business: Signage Rules (2026)

The Non-Coastal Zoning Ordinance takes a strict position on advertising a home occupation. Under NCZO Sec. 8107-1.2, subsection (c), signs advertising the home occupation are prohibited on the premises, and the address or location of the dwelling shall not be disclosed in any form of advertisement or signage. This is part of the broader requirement that the existence of a home occupation shall not be evident beyond the boundaries of the property on which it is conducted (subsection (h)), and that no internal or external alterations to the dwelling that are not customarily found in such structures are permitted. The ordinance also reaches business vehicles: under subsection (g), any lettering on a commercial vehicle that is associated with the home occupation shall not divulge the address of the dwelling where the home occupation is located. Likewise, subsection (a) prohibits displaying merchandise, produce, or other materials or equipment for advertising purposes. Together, these rules mean a compliant home business in the unincorporated county generally cannot post a yard sign, window sign, or any exterior signage naming the business or address. Operators can still advertise off-site (online, print, etc.) so long as the dwelling's address or location is not disclosed. These standards apply in addition to any general sign regulations in the County's zoning code.
