5 rules for unincorporated Mono County, California.
Verified from official government sources
Home occupations are permitted in all residential designations in unincorporated Mono County, subject to a business license and the home-occupation standards in General Plan Section 04.290. The business must be incidental and secondary to the residence, run by resident family members, with no outside employees and no neighborhood traffic impact.
In unincorporated Mono County, signs advertising a home occupation are NOT permitted unless allowed through an Expanded Home Occupation Permit (Sign Code Section 07.060(8)). Standard home occupations may show no external evidence. A private residence may post only a 2 sq. ft. identification sign with the occupants' names.
Cottage food operations in unincorporated Mono County are governed by California's Cottage Food Law and administered locally by Mono County Environmental Health. Class A operators register with a self-certification checklist; Class B operators register and obtain a permit after a home-kitchen inspection. Only CDPH-approved non-hazardous foods are allowed.
Family daycare homes in unincorporated Mono County are protected by California state law. Health & Safety Code 1597.45 makes small and large family daycare homes a residential use 'by right' for all local zoning, and bars local business-license fees for them. Operators license through the state, not through County zoning approval.
A standard home occupation in unincorporated Mono County needs a business license and must meet the Section 04.290 home-occupation standards — no separate discretionary permit. To exceed those limits (outside employees, signage, greater visibility), an Expanded Home Occupation Permit is required, approved by the Planning Commission at a public hearing.
