MI HB5584

Duplexes must be permitted as of right in any zoning district that allows single-family residences, subject to the same permitting procedures as single-family homes.

Local governments cannot impose bulk or size requirements that would prevent duplexes from having at least 1,000 square feet of habitable floor space per unit, including restrictions on lot coverage, setbacks, height, or floor area ratio.

Parking requirements for duplexes are capped at 1 space per residential unit, including guest parking, subject to ADA requirements.

Design, aesthetic, height, placement, and other requirements imposed on duplexes cannot be more restrictive than those applied to single-family residences.

The act takes effect 180 days after enactment.
