Parking Garage Property Tax Appeals

Downtown parking demand tracks downtown office occupancy almost perfectly — and with hybrid work compressing weekday office attendance to roughly two-to-three days in most markets, contract parking revenue has dropped 20–40% below 2019 stabilized figures in many central business districts. Yet assessments across Michigan, Indiana, and Ohio still anchor to pre-2020 stabilized occupancy and revenue, producing assessed values that materially exceed what a buyer would pay today. Documenting the actual monthly contract count, daily transient revenue, and event-driven income for the current and prior two years is the foundation of a defensible appeal. Owners of attached office buildings often have parallel grounds for appeal on the same campus.

Parking cap rates run higher than office or retail cap rates because investors price in operational complexity, single-use risk, and the sensitivity of revenue to surrounding land-use mix. Standalone downtown decks typically trade at higher cap rates than mixed-use garages attached to a credit-tenant office or hotel, and older structures with deferred maintenance carry a further premium. Assessors who plug a generic commercial cap rate into a garage NOI produce an inflated value — sometimes by 25–40% versus what a market participant would actually pay. Our cap rate and property tax resource explains how the wrong cap rate alone can be the entire over-assessment, and our free review tests yours against current parking market data.

Yes — and assessors routinely under-deduct it. Garages built before the 1990s were designed for smaller passenger vehicles, with seven-foot ceiling clearances, tight ramp radii, narrow stall widths, and column spacing that makes modern SUV and pickup truck use awkward or impossible on certain levels. Older structures also predate current ADA accessibility standards, EV-charging infrastructure expectations, and the structural reinforcement schedules that long-life concrete decks now require. Each of these is functional obsolescence that should reduce the assessed value in either the cost approach (depreciation) or the income approach (cap rate adjustment). Quantifying the retrofit gap with engineering estimates is central to the appeal — see our guide to property tax appeal evidence for what documentation moves a tribunal.

Mixed-use sites — a parking deck below or beside an office tower, a retail anchor, or a hotel — raise carve-out questions that produce some of the largest over-assessments we see. The garage portion is often valued as if its income were the contract rent paid by the attached office or retail user, when in fact a chunk of that rent is a captive intra-portfolio transfer rather than market parking revenue. Triple-net lease structures can further complicate the income picture, because the landlord, not the parking operator, may carry the tax burden — see our resource on triple-net leases and property taxes. Carving the parking component out of the larger parcel, valuing it on standalone market parking economics, and documenting the captive-versus-market revenue split is core to a defensible mixed-use parking appeal.

Parking garages contain a mix of real property (the concrete structure, ramps, elevators), fixtures (gate equipment, ticket machines, payment kiosks, LED signage), and personal property (revenue control software, license-plate-recognition cameras, removable barriers) — and assessors regularly fold fixtures and personal property into the real-property assessment. License plate recognition systems, mobile payment hardware, and EV-charging stations are particularly prone to misclassification because they often appear on the asset schedule without a clear real-versus-personal designation. Each line item that moves from real property to personal property reduces the assessed real-property value, and in Michigan, where small-taxpayer industrial personal property is exempt, the reclassification can wipe out the tax entirely. Start with a free assessment review to identify what should be reclassified.

EPTA represents parking garage and parking deck owners across Michigan, Indiana, and Ohio. In Michigan, parking garage appeals are filed at the Michigan Tax Tribunal, with petitions typically due May 31 or July 31 depending on property classification — income approach methodology is governed in part by MCL 211.27. In Ohio, complaints are filed with the county Board of Revision generally by March 31 following the tax year at issue, with the income approach codified at ORC 5713.03. In Indiana, cases proceed through the county PTABOA and, if necessary, the IBTR. We carry every step on contingency — no fee unless we reduce the assessment.
