Bill Summary · HB 5530

Purpose and intent

  • HB 5530, introduced for the 2025-2026 Michigan legislative session, amends the Michigan Zoning Enabling Act (and, in related bills, the Land Division Act) to reform minimum parcel size rules and related zoning and site-plan processes.
  • The overarching aim is to curb or standardize minimum lot sizes for new detached single-family residences when public water and sewer are available, and to tighten procedural requirements around site plans, protest petitions, and related processes.

Key provisions

Minimum parcel size for detached single-family lots (Sec. 205f)

  • A zoning ordinance may not impose a minimum parcel size greater than 1,500 square feet for land zoned for a detached single-family residence if:
    • The parcel will be served by public water and public sewer.

Related provisions in the Land Division Act (HB 5529, summarized for context)

  • Prohibits municipalities (or counties with authority) from enacting ordinances that set a minimum parcel size greater than 1,500 square feet for parcels with detached single-family residences served by public water and sewer.
  • In final plats, may allow residential lots smaller than the current minimum (12,000 square feet) but not less than 1,500 square feet if served by public water and sewer.
  • Eliminates the 7,200-square-foot waiver threshold for contiguous parcels owned since September 1, 1992 to qualify for waivers, tightening waiver eligibility.

Site plans and review (HB 5531)

  • Requires local governments to:
    • Develop and provide blank site plan application forms.
    • Require site plans to be submitted with completed forms.
    • Permit review of reasonable studies or documents necessary to evaluate the proposal’s nature, scope, and intensity.
  • After initial site plan approval:
    • Governments cannot require additional studies or material changes unless necessary to ensure compliance with zoning standards, federal/state law, or to address a demonstrated public health or safety concern.
  • If a proposed change to the site plan occurs, additional studies are not required unless needed to assess impacts of the change.
  • Mandates a 60-day decision period on site plan applications, with explanations required for rejections or conditional approvals to support appeals.

Protest petitions and signature requirements (HB 5532)

  • Revises protest petition requirements for zoning ordinance amendments:
    • Increases the outward boundary for the second area from 100 feet to 300 feet.
    • If the amendment increases the number of dwelling units, petition signatures must meet stricter criteria (60% of area ownership or tenants within 300 feet, rather than 20% ownership only in the immediate area).
  • Requires local clerks to verify land ownership of petition signers.
  • Specifies petition content, including summaries, parcel descriptions, signer information, and circulator certifications.
  • Establishes misdemeanor penalties (up to $500 fine, up to 93 days jail, or both) for improper petition practices (e.g., duplicate signatures, false ownership statements, falsified circulator certificates).

Who/what is affected

  • Local units of government (cities, villages, towns, and counties with zoning and land division authority), and the processes they administer (zoning, site plans, plat approvals).
  • Developers, landowners, and applicants affected by minimum parcel size rules, final plats, and site-plan requirements.
  • Petition organizers and participants in protest petitions, with changes to who can sign and how petitions are verified and certified.

Procedural and timeline aspects

  • Site plan decisions: Local units must decide within 60 days of receiving a site plan; decisions must include explicit justification for rejections or conditional approvals.
  • Effective scope of site-plan requirements: Controls on requiring additional studies after initial approval, and limits on reopening issues.
  • Petition process: Expanded verification duties for clerks and more stringent signature and circulator certification requirements; increased potential penalties for noncompliant petition activity.
  • Fiscal impact: Projected to be minimal for state and many local units (HBs 5529-5530). Potential nominal revenue effects or cost variations for localities imposing site-plan fees (HB 5531) and unclear impacts on local courts and jails due to added protest petition penalties (HB 5532).
