"Is this a city/village rezoning that a 20% landowner protest petition can push to a supermajority vote, or a township/county rezoning that a citizen referendum petition can send to the ballot -- and does the site even sit somewhere with a zoning ordinance at all?"
One statute, consolidated in 2006, and still optional for a jurisdiction to adopt at all
The Michigan Zoning Enabling Act (2006 PA 110, MCL 125.3101 et seq., effective July 1, 2006) repealed and replaced three separate prior statutes: the City and Village Zoning Act (1921 PA 207), the County Zoning Act (1943 PA 183), and the Township Zoning Act (1943 PA 184). The Act's own repealer section preserved continuity deliberately -- it does not alter, void, or require readoption of any zoning ordinance that existed under the repealed acts, and pending litigation or permits based on those acts are unaffected. A zoning ordinance adopted decades ago under the old Township Zoning Act, for example, remains valid today; it is simply now interpreted and amended under the consolidated Act's procedures rather than the 1943 statute's.
The Act is explicitly permissive, not mandatory: a local unit of government (defined as a county, township, city, or village) "may provide by zoning ordinance for the regulation of land development," and nothing in the Act requires it to. A genuinely material fraction of Michigan's 1,240-plus townships and many smaller municipalities have historically operated without any zoning ordinance at all -- a site-screening fact that changes the entire entitlement pathway for a project (there is no rezoning process to navigate if there is no zoning ordinance to amend, though a jurisdiction without zoning may still regulate through other means, and one without zoning today can always adopt an ordinance later, including as an interim ordinance under Section 404 while a permanent one is drafted).
Jurisdiction itself has a specific overlap rule worth checking before assuming which body controls: "the zoning jurisdiction of a county does not include the areas subject to a township zoning ordinance." In practice, if a township within a county has adopted its own zoning ordinance, the county's zoning ordinance simply does not apply inside that township's borders -- a site inside a zoned township is governed by the township, not the county, even though the county itself may also have a zoning ordinance covering its other, unzoned townships.
Two very different ways a rezoning can be taken out of the applicant's hands
The Zoning Enabling Act gives Michigan two structurally different citizen-driven mechanisms that can alter or delay a rezoning outcome, and which one applies depends entirely on what kind of local unit of government controls the site -- a distinction a Michigan entitlement screen has to get right early.
| Protest petition (Sec. 403) | Referendum petition (Sec. 402) | |
|---|---|---|
| Applies to | Rezonings (amendments) by a city or village only | New zoning ordinances or amendments in a county or township |
| Trigger | Signed by owners of at least 20% of the land area in the proposed rezoning, or 20% of the land area within 100 feet of its boundary (publicly owned land excluded from the calculation) | A registered elector files a notice of intent within 7 days of the ordinance's publication, then has 30 days to gather signatures from registered electors equal to at least 15% of the total vote cast in the jurisdiction for governor at the last gubernatorial election |
| Effect | Approval requires a 2/3 vote of the legislative body instead of a simple majority -- and up to 3/4 if a local ordinance or charter sets a higher bar | The ordinance or amendment does not take effect until it is put to, and approved by, a majority of registered electors voting on it at the next regular or special election |
| Practical risk | A well-organized, hyper-local group of adjacent landowners can force a supermajority vote with no election required | A single registered elector can trigger a process that, if a valid petition is filed, can delay effectiveness by months and ultimately put the rezoning to a popular vote of the entire township or county electorate |
These are genuinely different tools, not two names for the same thing. A city/village rezoning application can face a protest petition; a county/township rezoning cannot (Section 403 applies only to cities and villages) -- but a county/township rezoning instead carries the referendum exposure that a city/village rezoning does not.
Both mechanisms sit on top of the baseline notice requirements the Act applies to any hearing: published notice in a newspaper of general circulation at least 15 days before the hearing, and individual notice to the property owner, all owners of record and occupants within 300 feet of the subject property (one occupant per unit unless a single structure has more than four units, in which case notice may go to the manager or owner to post). For a rezoning affecting 11 or more adjacent parcels, the requirement to notify individual property owners and list street addresses does not apply to that group.
Special land use, PUDs, and where MSHDA's own scoring rewards entitlement already in hand
Beyond a straight rezoning, the Act separately authorizes special land use approval (Section 502) and planned unit development regulations (Section 503) as tools a local unit of government may build into its zoning ordinance. A planned unit development can waive otherwise-applicable district requirements according to its own PUD-specific standards, need not apply uniformly across a jurisdiction, and (at a landowner's request) can include non-contiguous open space where the PUD regulations don't prohibit it -- both potentially useful tools for a scattered- or irregular-site LIHTC deal, but each one is itself a discretionary local approval with its own hearing and notice requirements, not a by-right path.
Where a site's entitlement status stands at the time of application matters directly to MSHDA's own scoring, independent of anything in the Zoning Enabling Act itself. The 2026-2027 LIHTC Scoring Criteria's Development Characteristics section (Section C) awards 3 points for Evidence of Proper Zoning (documentation that the site is already properly zoned for its intended use) and a further 3 points for Evidence of Site Plan Approval -- available only where the applicant can submit a letter from the local governing body confirming the relevant board or commission has reviewed the proposal, including the level of rehabilitation work, and that no further plan approvals or reviews (other than staff-level review) are necessary. Separately, the QAP's own General Threshold Requirements (Exhibit I, Item IV) require zoning evidence dated within one year of the funding round deadline regardless of whether the site scores those points, including a description of what steps, if any, are underway to obtain proper zoning where it is not already in place.
A live legislative fight over zoning preemption, and where TEFRA hearings actually happen
Two genuinely separate Michigan housing-policy tracks were moving on different timelines as of this research and should not be conflated. The Michigan Housing Opportunity Tax Credit -- the state's real LIHTC-adjacent state tax credit (not the nonexistent "MIHP" that a prior internal note referenced) -- was enacted via House Bills 5805, 5806, and 5807 together with Senate Bill 966, signed by Governor Whitmer on July 21, 2026 (HB 5807 became Public Act 31 of 2026); it authorizes MSHDA to award roughly $42 million a year in state housing credits, with set-asides for new-construction and preservation 4% projects and at least 30% directed to rural areas. That program is now law.
A separate, more sweeping statewide zoning-preemption package -- House Bills 5581 through 5585, which would amend the Zoning Enabling Act itself (HB 5585 specifically amends MCL 125.3102 and adds new Sections 207a and 516) to mandate accessory dwelling units by right in residential districts, cap minimum lot sizes, and limit parking mandates -- had not passed as of this research. HB 5585 was introduced February 24, 2026 and referred to the House Committee on Government Operations, where it remained without a floor vote recorded through the most recent legislative history checked. A screen relying on news coverage of Michigan's 2026 housing legislation should keep these two tracks separate: the tax-credit program is enacted and operating; the zoning-preemption bills are not law, remain contested (Michigan Townships Association and the Michigan Municipal League have both organized opposition), and their eventual scope and effective date -- if any -- cannot be assumed from the current bill text.
For bond-financed 4% deals, the relevant public-hearing requirement is not run by the local jurisdiction at all but by MSHDA itself, acting as the conduit bond issuer under 26 U.S.C. § 147(f) and the Treasury's final TEFRA regulations (effective for MSHDA bonds issued on or after April 1, 2019). MSHDA posts and holds its own TEFRA public hearings -- for example, a hearing held September 16, 2026 at MSHDA's Lansing office for a $6.41 million bond issuance financing The Monarch Apartments in the City of Ecorse, Wayne County, noticed 13 days in advance and open to written comment through the hearing date. This research did not confirm, in an MSHDA-specific document, exactly who signs off as the "applicable elected representative" required by 26 U.S.C. § 147(f)(2)(E) after MSHDA's hearing closes (comparable state housing finance agencies typically designate their Governor for this role); that specific approval step should be confirmed directly with MSHDA's bond counsel for a given transaction rather than assumed from this research.
Where this goes wrong
- Assuming Michigan zoning runs on one unified statute with no history -- the Michigan Zoning Enabling Act is only two decades old (2006) and repealed three prior, separately-administered acts for cities/villages, counties, and townships; ordinances adopted under those older acts remain valid without readoption.
- Assuming every Michigan township or county has an enforceable zoning ordinance. The Act is explicitly permissive ("may provide by zoning ordinance"), not mandatory, and a real number of Michigan townships have historically had none.
- Assuming a county zoning ordinance governs a parcel inside a township that has its own zoning ordinance -- the county's zoning jurisdiction explicitly excludes areas already subject to a township zoning ordinance.
- Treating the protest petition (city/village rezonings) and the referendum petition (county/township zoning ordinances and amendments) as the same mechanism, or assuming both apply to every rezoning -- they apply to different jurisdiction types and produce different outcomes (a supermajority vote vs. a public referendum election).
- Underestimating the referendum petition's practical timeline risk for a rural or township-sited deal -- a single registered elector's notice of intent, followed by a valid petition gathering signatures equal to 15% of the jurisdiction's last gubernatorial turnout, can delay an ordinance's effectiveness until the next regular or special election.
- Treating a Planned Unit Development or special land use approval as a by-right or expedited path -- both are discretionary local approvals under the Zoning Enabling Act, each with its own hearing and notice requirements, not a shortcut around a standard rezoning.
- Confusing the enacted Michigan Housing Opportunity Tax Credit (HB 5805/5806/5807 + SB 966, signed July 21, 2026, HB 5807 = Public Act 31 of 2026) with the still-pending statewide zoning/ADU preemption package (HB 5581-5585) -- one is law; the other, as of this research, was still sitting in House committee with no floor vote recorded.
- Referring to Michigan's state LIHTC-adjacent credit as "MIHP" -- that program name does not exist in Michigan; the real program is the Michigan Housing Opportunity Tax Credit (HOTC), MSHDA-administered.
- Assuming a local unit of government, rather than MSHDA itself, holds the TEFRA public hearing for a bond-financed 4% deal -- MSHDA is the conduit issuer and holds its own hearings at its own offices under 26 U.S.C. § 147(f) and IRC § 142.
- Assuming this research has confirmed exactly who signs the post-hearing TEFRA approval for an MSHDA bond issue -- that specific approval authority was not confirmed against an MSHDA-specific primary source in this pass and should be verified with MSHDA bond counsel before relying on it.
- Skipping MSHDA's own zoning-related scoring items (Evidence of Proper Zoning, 3 points; Evidence of Site Plan Approval, 3 points) when a site's entitlements are already fully in place -- these are real, separate scoring lines under Development Characteristics, distinct from the zoning threshold requirement everyone must clear.
