Bishop, CA Home Business: Signage Rules (2026)

Inyo County's Zoning Ordinance (Title 18) regulates signs through Chapter 18.75, and signs accessory to a permitted, accessory, or conditional use must comply with that chapter. For home occupations specifically, Chapter 18.78 requires that the activity cause no alteration in the residential character of the premises and produce no objectionable glare. As a practical matter, this limits a home occupation to a small, low-key identification sign rather than commercial-style advertising, illuminated signs, or window displays. In residential zones, the County's sign rules generally allow only a modest nameplate or identification sign for the dwelling and any permitted accessory use; large freestanding or off-site signs advertising a home business are not consistent with the residential-character standard. Because exact dimensions and any permit requirement for a particular sign are set in Chapter 18.75 and applied case by case, anyone planning a sign for a home occupation should confirm the maximum sign area, placement, and whether a sign permit is needed with the Inyo County Planning Department before installing it. Signs in the County right-of-way or that create traffic hazards are separately prohibited.
