Full Breakdown
Sign rules for home businesses are set by each city and township, not by Macomb County. The common Michigan approach bars any sign or outward advertising for a home occupation so the residence keeps its residential appearance. Macomb Township Zoning Ordinance Sec. 10.0320 imposes two controlling conditions: subsection C requires no change in outside appearance or other visible evidence of the business, and subsection H prohibits all indoor or outdoor advertising. Together these bar a yard sign, window sign, or exterior lettering. General (non-home-occupation) signage falls under the township's separate sign provisions and needs its own permit. Confirm the exact rule with your own city or township building/zoning department before posting anything.
Violations & Fines
Posting a prohibited home-occupation sign or advertising the business at a residence is a zoning violation enforced by the local municipality, which may issue a municipal civil infraction citation, order the sign removed, and impose fines.
