What can I build on commercial property in Macomb Township?

It depends which of the five commercial districts you are in, and they nest. O-1 and O-2 are offices only, no retail of tangible goods, with O-2 adding hotels and 10-story height (Sec. 10.1302; Sec. 10.1402). C-1 adds neighborhood retail and services inside enclosed buildings: drugstores, salons, dry cleaning drop shops, florists (Sec. 10.1502). C-2 adds general retail: restaurants without drive-throughs, supermarkets, department stores, package liquor, service stations with convenience stores; bars, hotels, drive-throughs, and outdoor sales need special approval (Sec. 10.1602; Sec. 10.1603). C-3 is for planned shopping centers of at least 50,000 square feet on 5 plus acres (Sec. 10.1702; Sec. 10.1706). C-4 takes everything in C-1 through C-3 plus the C-2 special-use list by right, and adds auto dealerships, repair garages, drive-ins, and amusement uses (Sec. 10.1802).

Every commercial project goes through Planning Commission site plan review (Sec. 10.2403), and each district carries a masonry wall plus greenbelt screening requirement against residential and MTC land, from 20 feet in C-1 up to 50 feet in C-3 and C-4 (Sec. 10.1505.G; Sec. 10.1705.G; Sec. 10.1805.G). Special land uses take a public hearing under Sec. 10.2402.
