All districts
Detached accessory buildings (garages, sheds, pole barns) follow Section 27.02.A township-wide:
- A principal building must already exist on the parcel, with one narrow exception for certain historically platted lakefront lots meeting the Section 27.02.A.1 conditions (amended 10.20.25).
- Placement: a detached accessory building meets the same front and side setbacks as the house, but the rear setback is only 10 feet (Section 27.02.A.4). Corner and multi-frontage lots follow the modified rules in the same subsection, and no detached accessory structure may extend past the leading edge of the house into the front yard.
- Size is capped by lot size (Section 27.02.A.8, amended 10.20.25). Detached floor area and total accessory floor area, counting every story: up to 1/2 acre, 750 and 1,150 square feet; over 1/2 to 1 acre, 900 and 1,300; over 1 to 2.5 acres, 1,000 and 1,500; over 2.5 to 5 acres, 1,900 and 2,500; over 5 to 10 acres, 2,400 and 3,000; over 10 acres, 3,200 and 3,800. Attached accessory buildings are separately capped at 75 percent of the principal structure.
- Larger buildings need a Zoning Board of Appeals variance, with combined coverage still capped at 20 percent of the lot in SF, SE, and SR or 25 percent in R-1, R-2, and R-3 (Section 27.02.A.9).
- Height: a detached accessory building in a residential district may not exceed the height of the house, unless it sits at least 150 feet behind the house, and never above the district height cap (Section 27.02.A.5).
- Accessory buildings count toward lot coverage, may not sit in a road easement, and may not host commercial operations other than a lawful home occupation (Section 27.02.A.4, 7, 11).
Farm buildings in the agricultural-friendly districts may reach 40 feet of height under the district footnotes (Section 5.02.J; Section 6.02.O).
