Upland, CA Home Business: Signage Rules (2026)

Signage for home-based businesses in Upland is tightly limited by the home occupation standards in Chapter 17.27 and the citywide sign rules in Chapter 17.15. The central rule for home occupations is that there must be no exterior evidence of the conduct of the business. Because a business sign would itself be exterior evidence inconsistent with the residential character the chapter is designed to preserve, advertising signage at the home is effectively not permitted for a home occupation. Beyond that, Chapter 17.15 governs all signs, advertising structures, and devices exposed to view from outside a building, including their location, type, size, height, design, quantity, content, and illumination. Animated, electronic changeable-copy, moveable, flashing, lighted, or rotating signs are expressly prohibited in all zones, with limited exceptions. Residential zones in particular are not intended to host commercial advertising. The practical takeaway for an Upland resident running a home occupation is that the business should not be identifiable from the street: no commercial signage, no window displays of merchandise, and no displayed inventory. Anyone seeking any form of on-site signage should confirm directly with the Planning Division what, if anything, is permitted, since the no-exterior-evidence standard is strict.
