ADU Rules
The Village of Mount Pleasant regulates accessory dwelling units in Chapter 90 (Zoning) of the Code of Ordinances, adopted under Wis. Stat. Sec. 61.35 (village zoning). Mount Pleasant uses two ADU forms: a 'backyard cottage' (a small detached accessory residential building containing a single self-contained accessory dwelling unit on the same lot as a detached house) and a 'secondary suite' (an attached accessory dwelling within the principal dwelling). Backyard cottages are allowed in all R (Residential) Districts on lots occupied by a single detached house and are subject to the lot and building regulations of Table 90-110-8. Only one backyard cottage is allowed per lot, and a backyard cottage is not permitted on a lot that already contains a secondary suite. Recent amendments presented to the Village Board lowered the maximum height for detached accessory structures to 20 feet (or the height of the principal structure, whichever is less), increased the detached accessory-structure setback from 6 to 10 feet, and added a Building Area Ratio (BAR) for new residential construction.

Some RestrictionsShed Rules
Sheds in the Village of Mount Pleasant are regulated as accessory structures under Chapter 90 (Zoning), Division 90-330 of the Mount Pleasant Code. Sec. 90-330 limits accessory uses and structures to lawfully established principal uses, requires them to be located on the same lot as the principal use, and requires that the principal use be in place first. The Village's permit threshold is generous: a private shed, deck, pool, or fence and a private garage or accessory structure of less than 750 square feet do not require a zoning compliance permit, while private garages and other accessory structures 750 square feet or larger do require a permit. All accessory structures must comply with the dimensional standards (lot coverage, setbacks, and height) of the underlying zoning district under Division 90-110 (Residential Districts) and the measurement rules in Sec. 90-510. Authority: Wis. Stat. Sec. 61.35 and Sec. 62.23.
