Oakland, CA Home Business: Signage Rules (2026)

Oakland caps home-business signage far below its general residential sign allowance. 112. 040(F) spells out the specifics: a home occupation may have exactly one sign, with a display surface of no more than one square foot on any face, and it must be nonmoving, with any illumination indirect and nonflashing. The same subsection bars any other outside or window display of the business's materials or products and prohibits any other exterior indication that a home occupation exists at the address; the residential appearance of the property, including a building's historic character-defining features, has to be preserved.

040(G) adds a related restriction on vehicles: no commercial or passenger vehicle carrying a sign that advertises or identifies the home occupation may be parked anywhere on the lot where that sign would be visible from a lot line. Together, the sign, display, and vehicle rules are meant to keep a home occupation invisible from the street beyond that single square-foot sign.
