Anza, CA Home Business: Signage Rules (2026)

Because home occupations must remain clearly incidental to the residential use of the property, Riverside County Ord. 348 § 18.28 explicitly forbids any exterior display, sign, or advertising visible from the street that would indicate a business is being conducted on the premises. This applies to wall signs, yard signs, banners, window signs, illuminated signs, and vehicle signage parked in view. The County Sign Ordinance (Ord. 521.2, later recodified into Article XIX of Ord. 348) regulates permissible signs by zone; residential zones (R-1, R-A, R-R, etc.) do not include home occupations as a sign-eligible use. Nameplate signs identifying the occupant (not the business) up to a small area (typically under 2 square feet) are allowed. Real estate, political, and address signs have separate allowances. Violation of the signage rule is a common trigger for home occupation complaints and can result in a Notice of Violation from Code Enforcement, with administrative citations escalating from $100 to $500 per occurrence under the County's general enforcement framework.
