Calaveras County, CA Home Business: Signage Rules (2026)

Signage for home businesses in unincorporated Calaveras County is governed by Chapter 17.24 of the Zoning Code. Section 17.24.100 (Allowed Signage) provides that nonresidential uses in residential zones, including home occupations and short-term vacation rentals, are permitted 'a single-sided sign without illumination,' provided the sign 'is mounted on the residence' and is 'no larger than twelve inches in height and twenty-four inches in length.' This works together with the home-occupation rule in Section 17.25.140, which requires that the residential appearance of the property be maintained and that there be no exterior indication of the home occupation except a sign consistent with the sign chapter. In practice this means a home business may post one small, wall-mounted, unlit sign of up to roughly two square feet and may not use freestanding, illuminated, animated, or oversized signage. Chapter 17.24 also contains general sign rules including exempt and prohibited sign categories, sign-height standards, and maintenance requirements that apply countywide. Because the County's Design Review provisions can add requirements in certain overlay areas, and the sign code includes specific prohibitions, owners should confirm sign details with the Planning Department before installing any home-business sign.
