Full Breakdown
Kern County Zoning Ordinance § 19.94.040(9) provides verbatim: 'No sign shall be permitted, other than the clearly posted address of the home.' This restriction applies to every home occupation permitted under Chapter 19.94 in unincorporated Kern County. The Planning and Natural Resources Department's Form 606 reinforces the rule in its published purpose statement: 'Under the County's Home Occupation Ordinance, employees other than the resident/applicant are not permitted, except as permitted under AB1616 (Food Safety: Cottage Food Operations), and no advertising signs are permitted on the property.' The address-only allowance means a residence may display the standard street-number sign required for emergency response, but may not add a nameplate, business name, logo, sandwich board, banner, or any other visible advertisement of the home occupation. The signage prohibition operates together with the broader 'residential appearance' policy implicit in Chapter 19.94: the home occupation must be conducted so that 'an average neighbor, under normal circumstances, would not be aware of its existence.'
Violations & Fines
Posting any home-occupation sign other than the clearly posted address violates § 19.94.040(9) and may trigger code enforcement under Title 19. The Planning Director may issue a notice of violation, require removal of the sign, and revoke the Home Occupation Permit. Continued display may result in administrative penalties and abatement under the County's general code-enforcement procedures.
