Home businesses in Pomona generally cannot display exterior signage. Pomona Zoning Code regulates sign locations and prohibits posting signs on public poles. Ordinance No. 4357 updated the city's sign regulations.
The Pomona Zoning and Development Code Sign section (updated May 7, 2025) governs all signage in the city. Signs posted on public poles are prohibited under PMC. Home-based businesses in residential zones are subject to strict sign limitations consistent with residential character. The Sign section regulates size, placement, materials, and illumination. All business signs require compliance with zoning standards. Specific home occupation signage limits should be reviewed in the current Development Code.
Unauthorized signs are subject to removal and code enforcement action. Contact Code Compliance at 909-620-2374.
