Can Ann Arbor Make Short-Term Rental Owners Move In or Sell? The $96 Million Claim, Checked

A restriction on short-term-rental use is not the same as a government purchase. That distinction changes nearly every step in a widely circulated cost estimate.

Last verified: August 16, 2026

Quick answer: Ann Arbor does not generally have to buy a property before it can regulate short-term-rental use. Michigan's 125% compensation rule applies when an individual's principal residence is taken for public use; it is not a surcharge on every non-owner-occupied rental affected by zoning or licensing. The much-discussed $96 million estimate also relies on parcel counts and a valuation field that cannot be reproduced from a published city table. The useful policy question is not simply whether owners would “move in or sell.” It is how many legal dwelling units would actually leave short-stay use, what those units would become, and what public cost—if any—would produce each verified housing outcome.

The Argument Starts With a False Choice

A recent Ann Arbor policy argument begins with a provocative idea: require owners of certain non-owner-occupied short-term rentals to make the property their principal residence or sell it. A separate numerical analysis then asks what it would cost the city to make that happen.

The analysis starts with a claimed 313 licensed parcels, removes parcels showing a full or partial Principal Residence Exemption, excludes certain large commercial buildings, and arrives at 124 parcels containing 188 housing units. It treats a reported city valuation of about $76 million as the value of those properties, adds Michigan's 25% principal-residence eminent-domain premium, and concludes that acquisition would cost about $96 million, or roughly $512,000 per unit.

The arithmetic is easy to follow. The legal and data premises are not.

Three different government or market actions have been compressed into one scenario:

1. Regulating a use: the city changes which properties may operate as short-term rentals.
2. A voluntary sale: an owner decides to sell on the open market after the economics of the property change.
3. Condemnation: the government takes a property interest for a public use under eminent-domain authority and pays compensation.

Only the third action necessarily begins an eminent-domain compensation analysis. A permit rule does not transfer title to the city. A voluntary sale does not become condemnation just because a regulation influenced the owner's decision.

That does not mean every possible phaseout would be lawful, simple or free of litigation. Ann Arbor recognizes some older non-principal-residence short-term rentals as lawful nonconforming uses, and their histories matter. It does mean that “regulate” and “buy” cannot be used as synonyms.

First, What Has Ann Arbor Actually Done?

The “move in or sell” idea is a 2026 council campaign proposal, not an enacted citywide sale mandate. The distinction is important because Ann Arbor already regulates short-term rentals and has not ordered licensed owners to transfer their properties.

Under the city's current framework, a short-term rental is generally a dwelling or part of a dwelling rented for 30 consecutive days or less. The ordinance recognizes three categories:

• a non-principal-residence short-term rental, also called a commercial rental;
• a principal-residence homestay, where a permanent resident remains onsite during the guest's stay; and
• a principal-residence whole-house rental, where the resident is away while guests occupy the home.

Ann Arbor's current short-term-rental guidance says only principal-residence properties may apply in residential zones. Non-principal-residence rentals are generally limited to eligible mixed-use districts. A qualifying commercial short-term rental established before March 1, 2021 may, however, continue as a lawful nonconforming use. Each unit needs a license, currently priced at $500 per unit per year. City of Ann Arbor: Short-Term Rentals · Ann Arbor STR Guide · Chapter 97 legislative file

This means the local debate is not about introducing owner-occupancy rules into a completely unregulated market. It is about future licenses, enforcement, unregistered operations and the treatment of existing or legacy uses.

On July 20, 2026, City Council adopted a resolution directing the City Attorney to prepare a six-month moratorium on new short-term-rental licenses while staff studies possible regulatory changes. The resolution allows for renewals in the contemplated draft and does not itself prove that a final moratorium ordinance had taken effect. As of this article's verification date, the city's legal-notices page did not show a final effective moratorium ordinance. Council Resolution R-26-301 · Ann Arbor legal notices

The safe description is therefore narrow: Council ordered a draft and a study. Ann Arbor did not enact the campaign slogan as a literal “move in or sell” command.

What an Owner Could Do After a Rule Change

Suppose a valid future rule prevents a particular property from continuing as a short-term rental. Selling is only one possible response.

The owner might:

• occupy the property as a principal residence;
• offer it under a long-term lease;
• sell it to a homebuyer;
• sell it to another investor who uses it lawfully;
• leave it vacant;
• seek another permitted use;
• apply under an exception or different license category; or
• challenge the rule or its application to the property.

Those choices have different effects on housing. A switch to a long-term lease may increase long-term rental availability. A sale to a homebuyer changes tenure but does not create a new physical housing unit. A vacancy produces no immediate housing-access gain. A city or nonprofit purchase can create controlled affordable inventory only if the buyer funds closing, rehabilitation, operations and an enforceable affordability term.

This is why the number of short-term-rental licenses retired is not, by itself, the number of homes added to the market.

Auditing the 313-to-124 Parcel Funnel

The public calculation is best treated as an unverified dataset hypothesis. Some of its subtraction works, but its inputs and classifications are not available in a reproducible official table.

The city FOIA log is useful evidence that source records exist, but a granted request is not the same as a public, auditable dataset. To validate the funnel, the analysis would need to publish at least a dated license status, parcel ID, zoning district, legal dwelling-unit count, legacy-use status, PRE percentage and year, property class, ownership form, valuation field and an inclusion reason for every row. Ann Arbor FOIA log

There is another denominator problem. Ann Arbor charges for licenses per unit, while the analysis moves among licenses, parcels, buildings and housing units. Those categories can produce different totals. One parcel can contain several legal units; a building can contain several parcels; a platform can show more than one listing for the same licensed unit; and a license can expire without the physical unit disappearing.

The proper inventory formula is closer to:

licensed STR units
− units outside the final policy's scope
− inactive, expired or revoked licenses
− duplicate records tied to the same legal dwelling
− protected or preserved legacy uses
= potentially affected legal dwelling units

Until that unit-level table exists, 124 parcels and 188 units should not be described as city-confirmed facts.

PRE Is Evidence of Residency, Not a Complete Occupancy Registry

Michigan's Principal Residence Exemption, or PRE, reduces certain school operating taxes on an eligible principal residence. In general, a qualified owner must own and occupy the property as the one true, fixed and permanent home to which the owner intends to return. Michigan Treasury: PRE background

That makes PRE useful evidence. It does not make PRE percentage a perfect switch for classifying every short-term rental.

Why not?

• The eligible owner has to claim the exemption.
• A tax roll can lag a move, transfer or rescission.
• Trust ownership can require beneficiary-specific analysis.
• Duplexes, multi-unit properties and mixed-use parcels can have partial PRE.
• An owner may rent part of a home and retain some or all eligibility, depending on the facts.
• Ann Arbor's STR ordinance can recognize a permanent resident who is a tenant of more than 30 days, while PRE is an owner-focused tax benefit.

The city's own STR guide lists PRE alongside other possible residency indicators, including a driver's license, voter registration, utilities, tax returns and financial statements. It does not say PRE alone decides the issue. Ann Arbor STR Guide · Michigan Treasury: Partial PRE · Michigan Treasury: Occupancy Requirement

This creates a sharp inconsistency in the $96 million argument. The calculation first selects parcels for lacking full or partial PRE, then assumes all selected parcels qualify for a constitutional premium reserved for an individual's principal residence. PRE and the constitutional term are not perfectly interchangeable, but the first screen is evidence against applying the premium to every parcel in the residual group.

Michigan Does Not Pay 125% for Every Taking

Article X, section 2 of the Michigan Constitution requires just compensation when private property is taken for public use. It adds a special floor: if the property consists of an individual's principal residence, compensation must be at least 125% of fair market value, plus other reimbursement allowed by law. Michigan Constitution, Article X §2

Each phrase matters.

• Individual: an LLC-owned or corporate investment property is not automatically covered.
• Principal residence: a second home, commercial building or non-owner-occupied investment is not automatically covered.
• Taken for public use: a voluntary purchase or a zoning restriction is not automatically a constitutional taking.
• Not less than 125%: even for a qualifying residence, 125% is a floor rather than a universal exact price.

Michigan's condemnation process also involves more than choosing a multiplier. The acquiring agency generally develops a valuation, makes a good-faith written offer, provides an appraisal or written basis, and may litigate if the parties do not agree. Public necessity, relocation and other statutory reimbursements can matter. Michigan Uniform Condemnation Procedures Act

A real acquisition model would therefore include, parcel by parcel:

appraised fair market value
+ any legally applicable constitutional or statutory amount
+ relocation and displacement costs
+ appraisal, title, environmental, legal and closing costs
+ rehabilitation and accessibility work
+ conversion and first-year operating reserves
= all-in public acquisition cost

The $96 million figure includes none of those additions. More importantly, it applies the principal-residence premium to a group selected largely for not showing PRE.

SEV Is Not Fair Market Value

The underlying analysis describes approximately $76 million as the city's total “valuation” for the selected parcels. That word is too vague to support an acquisition estimate.

Michigan tax records contain several different fields:

The Michigan Tax Tribunal defines State Equalized Value as one-half of true cash value and true cash value as fair market value or the usual selling price. Michigan Tax Tribunal glossary

If $76 million is a sum of SEVs, the tax-roll-implied aggregate true cash value would be approximately $152 million—not $76 million. But that does not establish a corrected $152 million purchase price. It only shows why the original valuation label must be identified. A condemnation appraisal still requires property-specific evidence, condition, interests taken and a valuation date.

Even the final multiplication is imprecise: $76 million multiplied by 1.25 is $95 million. Rounding different underlying figures could produce “about $96 million,” but precise output cannot repair an undefined input or an inapplicable legal premium.

Lawful Nonconforming Uses Require a Separate Analysis

The distinction between regulation and condemnation does not make legacy rights disappear.

Michigan's Zoning Enabling Act protects a land use that was lawful when a zoning ordinance or amendment took effect. Ann Arbor's guidance expressly recognizes qualifying non-principal-residence short-term rentals established before March 1, 2021 as legal nonconforming uses. A future phaseout would therefore need to address lawful-use history, permits, continuity, abandonment, transfer and the exact ordinance text. MCL 125.3208 · Ann Arbor STR Guide

A federal appellate decision involving New Buffalo, Michigan illustrates why facts matter. In that case, owners who had not obtained permits and had not established a lawful prior STR use failed to show the protected property interest needed for their claims. The unpublished opinion is useful as an illustration, not a ruling that resolves Ann Arbor's grandfathered properties. Moskovic v. City of New Buffalo

Michigan law also exposes a problem with the proposed public-housing shortcut. MCL 125.3208(3) authorizes a local government to acquire property to remove nonconforming uses, but says property acquired by a city or village under that subsection cannot be used for public housing. That does not bar every voluntary affordable-housing acquisition under every possible authority. It does mean this particular nonconforming-use mechanism cannot automatically turn legacy STR properties into public housing.

What Would Actually Add Housing?

Housing policy discussions often count four different outcomes as if they were the same:

• Physical stock: how many legal housing units exist?
• Availability: how many are offered for occupied long-term use?
• Tenure: are they owner-occupied or rented?
• Affordability: are rents or resale prices restricted for a defined term?

Changing a short-term rental to a long-term rental can improve availability without adding physical stock. Selling an existing house changes ownership without creating a unit. Acquiring a house for a public or nonprofit program can add controlled inventory, but only after funding, rehabilitation and occupancy. Building a project on underused land can add net new units.

A serious impact forecast should model owner behavior as ranges:

potentially affected units × conversion-to-long-term-rental rate
= added long-term-rental availability

potentially affected units × sale-to-owner-occupant rate
= existing units changing tenure

potentially affected units × vacancy-or-other-use rate
= no immediate housing-access gain

None of those rates is established by the license count alone.

Why the Arbor South Comparison Is Not Apples to Apples

The public analysis compares the hypothetical STR acquisition program with Arbor South and concludes that buying the selected properties would deliver a similar value per unit. The ratios are recognizable, but the comparison mixes different projects and financing structures.

Official Arbor South documents describe more than 1,000 proposed residential units, with versions ranging from 1,039 to 1,073 units and 209 planned income-restricted homes. The project also includes a hotel, retail space, parking structures, streets, sidewalks, utilities, transit work, public space and brownfield remediation. City Arbor South overview · Planning staff report

The approved Brownfield Plan estimates approximately $184.9 million of Priority One eligible activities and $160.2 million of Priority Two eligible activities, or about $345.1 million combined. Those are eligible project costs expected to be reimbursed through a long-term tax-increment structure subject to actual spending and agreements—not a one-time city check for housing units. Arbor South Brownfield Plan · Council file R-26-040

Using the disputed numbers, $96 million is about 28% of $345.1 million, while 188 units are about 18% of 1,039 units. But those percentages do not measure value for money. One numerator is an incomplete hypothetical acquisition estimate for existing properties. The other covers eligible costs for a multi-phase, mixed-use development that would add more than 1,000 homes and substantial infrastructure.

The comparison becomes useful only after choosing a common outcome, such as:

• public cost per net new housing unit;
• public cost per net new income-restricted unit;
• public cost per occupied affordable unit-year;
• cost per existing unit converted to an occupied long-term lease; or
• time from policy authorization to actual occupancy.

Without a common denominator, “cost per unit” can conceal more than it reveals.

Is $96 Million Really 15% of Ann Arbor's Budget?

Ann Arbor's adopted FY2027 budget includes approximately $650 million in total expenditures. Dividing $96 million by $650 million produces 14.8%, which likely explains the 15% claim. City of Ann Arbor FY2027 budget announcement

The calculation is not a financing plan.

The all-funds budget combines General Fund operations with enterprise, capital, restricted and other funds. Those dollars are not freely interchangeable or sitting in one account waiting to purchase houses. For perspective, the adopted FY2026 General Fund was about $147.4 million; the same hypothetical $96 million would equal roughly 65% of that amount. Neither percentage identifies available cash.

A credible acquisition proposal would need to specify:

• legal acquisition authority;
• funding source and restrictions;
• bond or other debt service;
• appraisal and transaction cost;
• rehabilitation and accessibility work;
• property management and replacement reserves;
• rent or resale restrictions; and
• the number of units actually occupied under the intended program.

Calling a proposal a percentage of “the annual budget” may create scale, but it does not answer whether the city can finance or operate it.

A Better Scorecard for Ann Arbor's STR Debate

Whether a reader favors tighter rules or stronger protection for existing operators, the same evidence should be required.

1. Publish the unit-level baseline

Report licenses, parcels, buildings, listings and legal dwelling units separately. Freeze the dataset to a date. Identify active status, zone, license category and legacy-use status.

2. Define the policy precisely

Is the proposal an enforcement campaign, a moratorium on new licenses, a future principal-residence rule, nontransferability, attrition, an immediate phaseout, a voluntary conversion incentive or an acquisition program? Each has a different legal and fiscal path.

3. Forecast destinations, not just exits

Estimate how many affected units would become long-term rentals, owner-occupied homes, vacancies or other lawful uses. Validate the estimate after implementation with permits, rental certificates and occupancy records.

4. Protect the relevant legal categories

Separate unlicensed operations from existing compliant licenses and lawful nonconforming uses. State the notice, renewal, appeal, transfer and phaseout rules.

5. Use the right valuation field

Do not substitute taxable value or SEV for fair market value. For voluntary or compulsory acquisition, use parcel-specific appraisals and include all-in conversion and operating costs.

6. Compare equivalent housing outcomes

Do not compare an existing-unit transfer with new construction solely by nominal “units.” Use net new units, occupied restricted units, affordable unit-years, delivery time and ongoing subsidy.

This scorecard does not decide whether Ann Arbor should tighten its rules. It makes the tradeoffs visible enough for that decision to be honest.

What an Ann Arbor Property Owner Should Preserve Now

No final “move in or sell” ordinance was identified in the reviewed record, so owners should not make irreversible decisions based on a campaign slogan or a draft direction alone. But anyone operating or planning a short-term rental should keep a dated compliance file.

Include:

• the current license and renewal history;
• the property's zoning district and permitted-use table;
• evidence of when lawful STR use began;
• advertisements showing the license number;
• rental inspection and Certificate of Compliance records, if applicable;
• principal-residency evidence used in the application;
• notices, complaints and city correspondence;
• ownership and transfer records;
• the ordinance version in effect on each relevant date; and
• every appeal, hearing or response deadline.

Frequently Asked Questions

Would Ann Arbor have to buy a home before restricting its short-term-rental use?

Not as a general rule. Zoning and licensing regulate use; condemnation acquires property. A lawful nonconforming use or a parcel-specific takings claim may require separate legal analysis, but regulation is not automatically a government purchase.

Has Ann Arbor ordered short-term-rental owners to move in or sell?

No such enacted mandate was identified. A 2026 campaign proposal used that framing. City Council's July 2026 action directed the City Attorney to draft a temporary moratorium on new licenses and ordered a broader study.

Does Michigan always pay 125% in eminent domain?

No. The state constitutional floor of at least 125% of fair market value applies when property consisting of an individual's principal residence is taken for public use. It does not automatically apply to every rental, commercial property or entity-owned investment.

Does a parcel without PRE prove that no one lives there?

No. PRE is relevant evidence, not a complete occupancy registry. Claim timing, ownership structure, partial use and Ann Arbor's recognition of certain long-term tenant-hosts can matter.

Is State Equalized Value the same as market value?

No. SEV is generally one-half of true cash value. Taxable value is another field used to calculate taxes and can be lower still. Neither automatically equals a purchase price or condemnation award.

Is the $96 million estimate verified?

No. The subtraction and some ratios can be reconstructed, but the underlying parcel table, valuation field, unit count and legal basis for applying a 25% premium to the selected properties are not established in a published, reproducible city dataset.

Would selling an STR add a housing unit?

No. A sale transfers an existing unit. Long-term availability increases only if the property becomes occupied under a long-term lease, owner occupancy or a controlled housing program. New construction is what increases physical housing stock.

Could the city condemn a legacy STR and turn it into public housing?

Not through MCL 125.3208(3)'s mechanism for acquiring property to remove a nonconforming use; that subsection says a city or village cannot use property acquired under it for public housing. A voluntary purchase or another legal authority would require a separate analysis.

Is Ann Arbor's six-month moratorium already in effect?

The July 20, 2026 resolution directed preparation of an ordinance. Confirm a final ordinance, enactment date, effective date and exceptions before treating the moratorium as operative.

Turn a Policy Headline Into a Dated Property File

If a license notice, renewal decision or enforcement letter changes what you can do with a property, Pine can help you organize the ordinance version, license history, zoning record, residency evidence, notices, deadlines and financial records into one dated file. That can expose missing facts and help you prepare focused questions for the city, assessor, insurer, accountant or a qualified Michigan attorney.

Pine does not decide whether a use is legally vested, calculate condemnation compensation, file an appeal or replace local legal advice.
