This bill prevents local zoning laws from stopping owners from connecting their accessory dwelling units to the same sewer system as their main home. It applies specifically to secondary living spaces that are owned by the same person and located on the same property as the primary residence. By adding a new section to the state's zoning enabling act, the legislation ensures municipalities cannot restrict this utility connection under these conditions. The change aims to simplify infrastructure setup for homeowners who build or rent out additional units on their land.
This bill amends Michigan's zoning enabling act to prevent local governments from completely banning short-term rentals if there is a demonstrated need for them in the area. It specifically prohibits municipalities from adopting or enforcing rules that would totally prohibit short-term rentals, unless no suitable location exists within the local unit or the use is unlawful. The legislation defines "short-term rental" by referencing the existing short-term rental act and ties its effectiveness to the passage of a companion bill.
HB 5581 sets a 500-square-foot minimum size requirement for new homes in Michigan, preventing local governments from imposing larger minimums through zoning ordinances. This directly affects homeowners, developers, and local municipalities that create zoning rules for residential construction. The bill amends Michigan’s zoning law by adding Section 205e, which explicitly prohibits zoning ordinances from requiring dwelling sizes greater than 500 square feet. It does not change other zoning regulations like land use types, building heights, or lot coverage. The bill is currently pending in the House Government Operations Committee.
HB 5531 requires local governments in Michigan to make a decision on site plan approvals within 60 days. It limits when officials can request additional studies or documents after initial approval, allowing such requests only for material changes, safety concerns, or to ensure compliance with existing standards - preventing new requirements unrelated to the project. This affects developers seeking land use approvals and local officials reviewing applications. The bill clarifies that extra studies cannot be used to delay projects or revisit issues already approved.
HB 5532 revises protest petition requirements for cities or villages amending zoning ordinances. For most changes, a protest petition must be signed by owners of at least 20% of the affected land area (or 20% within 300 feet of the boundary), but if the amendment increases dwelling units, it requires signatures from owners of at least 60% of the affected land area. The bill specifies detailed petition formatting, including land ownership verification by the clerk and warnings about false signatures, with penalties for fraud. This directly affects local governments proposing zoning changes and landowners who may protest such changes.
HB 5530 limits local zoning ordinances from requiring single-family home lots larger than 1,500 square feet in areas with public water and sewer service. It directly affects local governments that set zoning rules for residential neighborhoods, preventing them from imposing larger minimum lot sizes under these conditions. The bill adds a new provision (Sec. 205f) to Michigan's zoning law, ensuring that such ordinances cannot restrict lot size beyond 1,500 square feet when public utilities are available. This change applies specifically to detached single-family residences zoned for residential use. The policy aims to allow more compact housing development in utility-served areas.
HB 5583 would limit local zoning rules in metro areas by prohibiting minimum setbacks for homes or outbuildings that exceed 15 feet from the front property line or 5 feet from rear/side lines. It allows up to 25 feet of setback only near specific environmental features: wetlands, lakes/streams, or the Great Lakes shoreline as defined by state law. The bill applies to all local governments located within or adjacent to a federally designated metropolitan statistical area. This change aims to simplify zoning for residential development in urban and suburban regions while maintaining environmental protections.
HB 5582 limits local zoning rules for multifamily housing and mobile homes in Michigan. It prohibits municipalities from requiring more than one parking space per dwelling unit (including guest spaces) in multifamily residential developments, except where required by the Americans with Disabilities Act. The bill also prevents residential zoning from excluding mobile homes - defined under state law - through aesthetic or material restrictions not tied to public safety. These changes directly affect developers building multifamily housing and mobile home residents in communities governed by Michigan's zoning laws.
HB 5585 modifies Michigan's zoning laws to make it easier to add secondary housing units and mobile homes. It prohibits local zoning rules from implicitly excluding mobile homes based on aesthetics or materials not tied to public safety, directly affecting mobile home residents and developers. For accessory dwelling units (ADUs) - secondary housing units like backyard cottages - the bill automatically allows them in residential zones if they meet size limits (max 800 sq ft or 75% of the main house), maintain 5-foot setbacks, and are attached to or near an existing single-family home. ADUs under these rules no longer require public hearings or discretionary approval, and they do not count toward local density limits.
HB 5584 allows duplexes to be built in any zoning district where single-family homes are permitted, directly affecting homeowners, developers, and local governments in Michigan. The bill requires local governments to treat duplexes the same as single-family homes for permitting and prohibits them from imposing restrictions that would prevent duplex construction - such as minimum unit size requirements, excessive parking mandates, or stricter design rules. It specifically bans requirements like lot coverage limits, setbacks, or height restrictions that would make duplexes impractical, while allowing reasonable, non-discriminatory rules. This policy change aims to increase housing options by making duplex development more accessible in single-family neighborhoods.
