Macomb County does not zone home-based businesses; each city and township does. Local ordinances typically allow a home occupation only if it stays incidental to the residence, employs only family, uses limited floor area, and shows no outside evidence of the business.
Zoning of home-based businesses in Macomb County is a city/township function — the county has no zoning authority over residential land use. Standards vary, but Macomb Township Zoning Ordinance Sec. 10.0320 is representative, permitting a home occupation in a single-family dwelling only if it stays clearly incidental to residential use, uses no more than 200 square feet within the dwelling, is not in an accessory structure, employs only resident family members, involves no sale of goods manufactured elsewhere, generates only neighborhood-normal traffic, and creates no off-lot noise, vibration, glare, fumes, or odors. Hours are limited to 9:00 a.m. to 8:00 p.m. Check your own city or township ordinance and whether a permit or zoning-compliance certificate is required.
Operating a home occupation outside the local conditions — hiring non-resident employees, exceeding the floor-area cap, or using an accessory building — is a zoning violation enforced by the township or city, with notices, municipal civil infraction citations, and fines.
