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.

City-specific rules exist: Modesto has its own signage rules rules that differ from Stanislaus County's county-level regulations. If you live in Modesto, check the city-specific page instead.

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.

Frequently Asked Questions

Can I put up a sign advertising my home business in Stanislaus County?
Yes, but only one, and it cannot exceed two square feet, per Section 21.94.020(H). Anything larger, or any other visible sign of commercial activity at the property, means the use no longer qualifies as a protected home occupation.
Can I list my home address in an ad for my home business?
No. Section 21.94.020(I) bars advertising of any kind, including phone-book and newspaper listings, that depicts the address of the home occupation's location, regardless of how compliant the physical sign at the property is.
Does parking a work vehicle in my driveway count against the sign rule?
It can. Section 21.94.020(H) treats vehicles associated with the home occupation as visible evidence of the business, the same as an oversized sign, except for the specific contractor and trucking exceptions carved out in Section 21.94.020(J)(2) and (J)(4).
