All districts
Canton Township sizes accessory buildings by formula, not a flat cap (Section 2.03.D.1): the total floor area of all accessory structures may not exceed 33 percent of the house's floor area plus 1 percent of the lot area, may not exceed 25 percent of the rear and side yards, and platted subdivision lots are limited to two accessory structures. An attached garage built as an integral part of the house does not count against the formula.
Placement (Section 2.03.D.3): a detached structure must meet the district's front and side setbacks, sit behind the front building line of the house, and keep a 6 foot rear setback in every district. On double frontage lots, accessory structures are restricted to the central third of the lot (Section 2.03.B.1). Height is capped at the smaller of the house's height or the district maximum, unless the building sits at least 100 feet behind the house and 100 feet from neighboring homes, where 45 feet is allowed (Section 2.03.D.2).
Use limits: no accessory structure may be used as a dwelling or for any business (Section 2.03.D.4); one private garage per lot, for occupants' vehicles only (Section 2.03.D.5); no door taller than 9 feet in residential districts (Section 2.03.D.6). Nothing accessory may be built before the principal building exists (Section 2.03.A.1).
Pools: at least 5 feet from any property line, never in the front yard or a corner lot's street-side yard, 4 feet from buildings, 25 feet from a private well, and never in a recorded easement (Section 2.03.E). Ground-mounted solar arrays are rear-yard only, capped at 10 feet tall and 25 percent of the rear yard or house footprint (Section 2.03.I.5).
