Buena Park, CA Home Business: Signage Rules (2026)

Buena Park's home occupation conditions in the Title 19 Zoning Ordinance flatly limit signage: there shall be no signs or other structures except those permitted for a dwelling use in the zone, and a home occupation shall not present any external evidence of nonresidential activity such as appearance, noise, vibration, odor, lighting, or signs. Because residential dwellings are not permitted commercial or advertising signs, this means a home-based business in Buena Park generally cannot post any sign advertising the business at the residence. The City's broader sign regulations live in Division 9 of the Development Code (Chapter 19.904 General Sign Provisions and related chapters), with the substantive commercial sign allowances in Chapter 19.912 (Sign Standards for Commercial and Industrial Zones) - confirming that business signage is oriented to non-residential zones, not homes. The practical effect is that customers cannot identify a Buena Park home business by exterior signage; the business must look like a normal residence from the street. This 'no external evidence' standard is a hallmark of the City's home occupation program and is enforced by Code Enforcement alongside the residential character requirements. These are City of Buena Park standards.
