Cost segregation for parking structures
A parking garage is mostly a concrete deck, and the deck is 39-year structure — so this is a low-ceiling asset by design. The reclassification is not the ramps and slabs; it is the equipment and coatings bolted onto them: lighting and ventilation, revenue-control gear, traffic membranes, and increasingly EV chargers. Together those short-life lines put a garage in an 8–20% modeled range.

1What reclassifies in a parking structures
In a parking structure, cost segregation typically reclassifies 8–20% of depreciable basis out of the 39-year building shell into 5-, 7- and 15-year property. The components that recur:
| Component | Recovery period | Authority carried (with caveat) |
|---|---|---|
| Lighting & ventilation / CO monitoring — LED fixtures, exhaust fans, CO sensor network | 5-year | Equipment serving operations and air quality may qualify depending on whether it is machinery rather than a structural building component. |
| Revenue-control equipment (PARCS) — entry/exit gates, ticket dispensers, pay-on-foot stations, LPR | 5-year | Access and payment equipment may be §1245 depending on whether it is business equipment rather than part of the structure. |
| Traffic coatings & deck sealers — waterproofing membranes, wearing-surface coatings | 5- or 15-year | Applied coatings may qualify depending on whether they function as a protective/finish layer versus part of the structural deck. |
| Signage & wayfinding — level markers, dynamic space-count displays, directional signage | 5-year | Directional and dynamic signage may qualify depending on whether it is business equipment rather than a permanent structural element. |
| Drainage — trench drains, oil/water separators, pumps | 5- or 15-year | Drainage components may qualify depending on whether they serve equipment/operations versus function as structural site drainage. |
| EV chargers — charging stations, dedicated conduit and switchgear | 5-year | Charging equipment may be §1245 depending on whether it is dedicated operating equipment rather than base electrical infrastructure. |
2Typical results and what drives the spread
Across standardized parking structure configurations, the engine models an accelerated share of roughly 8–20%. Position inside the 8–20% modeled range rises with how equipment-rich the garage is — automated PARCS, extensive ventilation, EV charging, and fresh traffic coatings — versus a bare open-air deck. These are modeled ranges, not a promise for any specific building — see by the numbers.

6Is it worth it — break-even
Because the concrete deck dominates, a garage generally needs a larger absolute basis for the benefit to clear a study fee, but a well-equipped structure with PARCS, ventilation, and EV charging reaches worthwhile numbers sooner, especially where bonus depreciation applies to the eligible basis.
7Frequently asked questions
Why is the reclassification percentage so low for a garage?
Because the building is overwhelmingly structural concrete — decks, ramps, columns, and slabs — all of which are 39-year property. The short-life basis is limited to the equipment and coatings added on top, which is a small share of total cost, so the ceiling is inherently low.
If the percentage is low, is a study even worth it?
It can be, on absolute dollars. A large garage with automated revenue control, extensive ventilation, EV charging, and recent traffic coatings can produce a meaningful short-life figure even at a modest percentage. The equipment lines, not the rate, decide whether it pays.
Are the entry and exit gate systems short-life property?
The PARCS equipment — gates, ticket dispensers, pay stations, and license-plate recognition — may qualify as §1245 property, depending on whether it functions as business equipment rather than part of the structure. That gear is typically among the strongest short-life items in a garage.
Do EV chargers change the analysis?
They can add short-life basis. The charging stations and their dedicated equipment may qualify, depending on whether they are operating equipment rather than base electrical infrastructure. As garages add charging capacity, this is a growing piece of the reclassification.
What about the waterproof coating on the decks?
Applied traffic coatings and sealers may qualify, depending on whether they function as a protective finish layer versus part of the structural deck itself. An engineer distinguishes the wearing surface from the structure, so only the defensible portion is reclassified.
