Bill
HB 4081
The bill expands parceling rules to allow up to 10 parcels from the first 10 acres after one year, boosting buildable lots and local authority to loosen divisions.
Status / Procedural history
- Introduced: Feb. 12 / filed Mar. 7, 2025 (Rep. Jay DeBoyer primary sponsor).
- Passed the House (substitute H‑1 adopted) April 16, 2025; referred to the Senate (Local Government).
- Committee reports and bill text specify the act takes effect one year after enactment (one document version cites July 1, 2026 as the operative date).
Purpose / Intent
- Increase flexibility for dividing ("platting") land under Michigan’s Land Division Act to enable creation of more buildable lots from certain parent parcels, with the stated aim of supporting housing production and making smaller tracts more usable for development.
Key provisions (what the bill changes)
- Raises the cap on how many parcels can be created from the first 10 acres of a parent parcel/tract:
- For the first year after the bill’s effective date, the status quo remains (up to 4 parcels for the first 10 acres).
- Beginning 1 year after the bill’s effective date, the first 10 acres (or fraction) may be divided into up to 10 parcels.
- Other parcel-count calculations remain in place:
- +1 parcel for each additional whole 10 acres beyond the first 10 (up to 11 additional).
- +1 parcel for each whole 40 acres beyond the first 120.
- Local-option authority:
- Beginning on the bill’s effective date, a municipality or county that has authority under section 109 may, by ordinance, authorize partitioning/splitting into more parcels than Section 108 would otherwise allow — provided local standards are met.
- Parcels or tracts created under such a local ordinance (or under the bill’s exempt-split rules) generally cannot be further partitioned without triggering the platting requirements, except as the ordinance or specified exempt-split rules permit.
- Other technical provisions:
- Special rules for large parcels (e.g., 40+ acre parcels not counted toward the parcel cap if accessible).
- Limited additional parcels for parent tracts ≥20 acres under certain road/access or minimum-size conditions.
- Conditions governing subsequent splits of parcels created by an exempt split (e.g., 10‑year waiting period, limits on resulting parcel counts).
Who is affected
- Landowners and developers (more opportunities to create buildable lots on smaller tracts).
- Municipalities and counties (new authority to set local standards to allow greater divisions).
- Local planners, surveyors, drain commissioners, utilities and public works (potentially increased demand for infrastructure, review, and drainage oversight).
- Local taxing units (possible changes to property tax base; fiscal impact depends on how parcels are developed).
Potential impacts and concerns
- Supporters argue it will increase lot supply and help address housing shortages by making small-tract development more feasible.
- Opponents (surveyors, county drain commissioners, planning associations) cite risks of insufficient oversight, sprawl, increased infrastructure and drainage costs, and long‑term land‑use complications from hastily or poorly planned divisions.
- Fiscal impact is indeterminate: subdividing a parcel could increase or decrease total local/state tax revenue depending on subsequent development patterns.
Notes
- The bill amends Section 108 of the Land Division Act (MCL 560.108). Nonpartisan fiscal/committee analyses accompanying the bill flagged the indeterminate fiscal effect and recorded positions of supportive and opposing stakeholder groups.
