Sierra County, CA Home Business: Home Occupation Permits (2026)

Unlike many jurisdictions, Sierra County's zoning code (Sierra County Code Title 15) has no dedicated home-occupation permit chapter and no separate home-occupation definition in its definitions (Sierra County Code Chapter 15.08). Instead, home occupations are authorized through the conditional-use mechanism. In the R3 residential multiple-family district (Sierra County Code section 15.12.100), 'home occupations' are expressly listed among conditional uses, and the code states that all conditional uses are 'subject to the issuance of a use permit.' Application fees for zoning entitlements, including use permits, are set in Sierra County Code Chapter 15.16. A use permit is discretionary: the Planning Commission or Planning Department reviews the proposed business for compatibility with the surrounding residential area and can attach conditions covering items such as hours, traffic, parking, and signage. In districts where home occupations are not listed, a home business may need a different entitlement or may not be allowed, so the parcel's specific zoning district controls. Because the County is the land-use authority for all unincorporated areas (Loyalton being the only city), residents from Sierraville to Sierra City apply through the Sierra County Planning Department in Downieville.
