All districts
The Macomb Township Zoning Ordinance contains no accessory dwelling unit provision. No section of Article II definitions, Article III general provisions, or the residential district articles authorizes a second dwelling unit, guest house, or accessory apartment on a single-family lot. The AG, R-1-E, and R-1 use sections each limit lots to one principal dwelling (Sec. 10.0402.B; Sec. 10.0602.A; Sec. 10.0702.A), and Sec. 10.0330 bars residential structures on the rear of a lot or on a lot with another dwelling, with a narrow farm tenant house exception in AG. Accessory buildings may not be used for any business or occupancy beyond incidental uses (Sec. 10.0331.10), and a mobile home may serve as temporary living quarters only during construction of a house, for up to 6 months (Sec. 10.0317).
This is a verified absence as of the July 2026 review of Supp. No. 35, not a statement that the township will never allow one; a homeowner wanting an in-law arrangement should ask the Planning Department at 586-992-0710 what, if anything, is possible on their lot.
