Bannock County, ID Home Business: Signage Rules (2026)

Section 17.52.270(H) of the Bannock County Code sets a hard, low ceiling on identification signage for any home-based business operating in the Residential Rural, Residential Suburban or Recreation zoning district: the sign cannot exceed four square feet in size. The county requires the sign to be flat-mounted directly on the dwelling itself, meaning it cannot stand on a pole, hang from a post, or otherwise project from the building, and it cannot be directly illuminated with spotlights, floodlights, or internal lighting. The rule extends beyond a fixed sign at the house: subsection H separately bars any sign on a business vehicle from displaying the home occupation's address, regardless of where that vehicle is stored, so an owner cannot get around the size cap by parking a lettered work truck in the driveway as a de facto business sign.

The signage limit sits within the broader set of conditions in Section 17.52.270 that keep a home occupation secondary to the residential use of the dwelling, including a companion rule in subsection G that forbids any yard or window display indicating a business operates at the address. Read together, the two provisions mean a home business in unincorporated Bannock County may identify itself only with the single, small, flat, unlit sign the code allows and nothing else visible from the street. Planning and Development Services reviews compliance with the sign standard as part of the zoning permit process for the home occupation itself, since no separate sign permit track exists for this specific use in the ordinance.
