Alhambra, CA Home Business: Signage Rules (2026)

Two operational standards inside Alhambra's home occupation section combine to create a complete sign ban. 170(E)(1) requires that the residential appearance of the unit within which the home occupation is conducted shall be maintained, and no exterior indication of a home occupation is permitted, meaning nothing about the outside of the house, from paint to displays, may reveal that a business operates inside. 170(E)(13) then addresses signage directly: no signs shall be permitted for a home occupation. Unlike commercial businesses, which are governed by Alhambra's separate sign chapter, a home-based operator gets no sign allowance at all, not even a small identification plate at the door or a name on a mailbox tied to the business.

170(C)(3)(b) separately requires that operation to abstain from posting signage or other outdoor displays advertising the microenterprise home kitchen operation, so the no-signage rule reaches even the state-protected cottage food category. Direct sales from the site are also barred under subsection (E)(7) except by mail, phone, internet, or other remote means, reinforcing that a home occupation cannot look or operate like a storefront; the sign ban is one piece of a broader rule keeping home businesses invisible from the street. The provision was adopted by Ordinance 4823, passed January 22, 2024.
