Summary
Sign rules for a home business are set by your city or township, not Genesee County. Michigan's Zoning Enabling Act expressly lets local governments regulate advertising tied to a home occupation.
This section does not prohibit the regulation of noise, advertising, traffic, hours of operation, or other conditions that may accompany the use of a residence under this section.
Full Breakdown
Genesee County does not regulate home-business signs; sign size, placement, illumination, and whether any sign is allowed at all come from your local zoning and sign ordinances. Most Genesee County communities either prohibit home-occupation signs or cap them at a small non-illuminated nameplate to preserve residential character. The Michigan Zoning Enabling Act, which authorizes home-occupation rules, specifically states that the mandatory craft/fine-art home-occupation allowance does not prohibit local regulation of advertising, among other conditions. Check with Flint, Grand Blanc, Fenton, Flushing, or your township building/zoning office before posting any business sign at a residence.
Violations & Fines
An unpermitted or oversized home-business sign is typically a municipal civil infraction: the city or township can order removal and levy a fine set by local ordinance.
