Summary
A home-based business in unincorporated Stanislaus County can post exactly one sign, and it cannot be bigger than two square feet. Section 21.94.020(H) treats any larger sign, or any other visible change to the property's outside appearance, as evidence the use has stopped being a home occupation and become an unpermitted commercial operation.
H. There shall be no change in the outside appearance of the building premises, or any visible evidence of the conduct of such home occupations other than one sign not to exceed two square feet. Visible evidence shall include, but not be limited to, any vehicles associated with the home occupation, except as allowed by Section 21.94.020(J)(2) and (J)(4).
Full Breakdown
020(J)(2) and (J)(4). 020(I), which bars any advertising, including phone-book and newspaper listings, that discloses the property's address, the sign standard is designed to keep a home occupation invisible from the curb: a single small identification sign is the only outward sign the property is anything other than a private residence. 020(F), showing the county treats home-business signage as a narrower carve-out than ordinary residential signage.
Violations & Fines
A sign larger than two square feet, or any other visible commercial marker on the property, takes the use outside Section 21.94.020's protection and turns it into an unpermitted commercial use subject to code enforcement. Stanislaus County Code Section 1.36.010 makes a code violation a misdemeanor punishable by up to a $1,000 fine and six months in county jail, and Section 1.36.020 allows the county to instead cite escalating infraction fines of $100, $200 and $400.
