Warren, MI Home Business: Zoning & Home Occupation Permits (2026)

29 of Warren's Zoning Ordinance defines a home occupation as an occupation or profession carried on only by a family member residing on the premises, and it bundles the operating limits directly into that definition. No commodity may be sold on the premises. No one may be regularly employed for the business except an immediate family member who lives there. No mechanical equipment may be used beyond what is normally used for domestic or household purposes (the ordinance carves out one exception, the office of a veterinarian).

The home occupation cannot occupy more than 25 percent of the dwelling's total floor area. The signage allowance is folded into the same sentence: one non-illuminated name plate no larger than one square foot, mounted at the building entrance. ' That means an R-2 homeowner cannot simply start a qualifying home business; the Zoning Board of Appeals must sign off first. 29's standards directly as a permitted accessory use without a separate Board of Appeals hearing, so the compliance burden in those districts falls on staying within the four listed conditions rather than obtaining prior approval.
