Cost segregation for big-box retail
A big box is a simple building on an enormous site. The shell is deliberately plain — a large sales floor, a receiving dock, and a wall of storefront glass — but the parking field wrapped around it is often the single largest depreciable improvement on the property, which is why the 15-year pool tends to dominate the study.

1What reclassifies in a big-box store
In a big-box store, cost segregation typically reclassifies 12–28% 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) |
|---|---|---|
| Parking field paving, curbing & striping | 15-year | The site's paving and curbing generally qualify as land improvements; on a big-box lot this is usually the largest single item, and the depreciable share depends on the basis the study can attribute to the lot rather than land. |
| Site & parking-lot lighting | 15-year | Pole-mounted site lighting serving the parking field generally qualifies; wiring that crosses into building loads is an engineer-review split and only the exterior-serving portion follows the land improvement. |
| Storefront, entry vestibule & display lighting | 5-year | Decorative display lighting and non-structural vestibule finishes may qualify where they serve merchandising rather than the building; the structural storefront framing and glazing generally stay 39-year. |
| Interior decorative finishes & department millwork | 5-year | Removable decorative finishes and non-load-bearing fixtures may qualify; anything integral to the structure or life safety stays 39-year, and the split is a facts-and-circumstances review. |
| Receiving-dock equipment — levelers, seals & bumpers | 5-year | Dock levelers, seals and bumpers that serve loading operations may qualify as equipment; the dock's structural slab, pit and framing generally stay 39-year. |
| Grocery-anchored refrigeration package | 5-year | Where a big box is grocery-anchored, removable refrigerated cases and their dedicated condensers may qualify; the insulated walk-in envelope generally stays 39-year, and a non-grocery box carries none of this. |
2Typical results and what drives the spread
A typical range for big-box stores runs 12–28% — general industry experience for this property type, not an output of our engine. A grocery-anchored box with a large lot runs toward the high end; a bare dry-goods box on a modest site sits lower. Either way this is not a promise for any specific building — see by the numbers.

4What a study costs for this type
Study fees track building size, documentation quality and whether an on-site inspection is performed. A big-box store study typically runs in the $6k–18k range — an indicative band, not a quote, since the fee scales with depreciable basis. See the pricing guide for how Cost Seg Smart's fees scale by basis and which providers publish prices at all; most competitors are quote-only.

6Is it worth it — break-even
Big boxes concentrate short-life value in the site, so the land-improvement pool tends to set the outcome and the shell contributes relatively little. On a store with meaningful depreciable basis, shifting 12–28% into 5- and 15-year pools pulls deductions forward — strongest in the placed-in-service year if bonus depreciation applies, and weaker if the hold is short enough that recapture erodes the timing benefit. Whether the box is grocery-anchored is what pushes a given property toward the top of that band.
7Frequently asked questions
Why does the parking lot matter so much for a big box?
Because the building is a simple shell and the site is enormous. On a big-box property the paving, curbing, striping and pole lighting can represent the largest block of depreciable improvements, so the 15-year land-improvement pool often carries the study more than the interior does.
Does a plain retail shell have much to accelerate on the inside?
Less than an equipment-dense property. Display lighting, decorative finishes and department millwork may qualify where they serve merchandising rather than the structure, but a deliberately simple box concentrates its short-life value in the site, not the sales floor.
Does refrigeration count if the box isn't a grocery store?
Only where there's grocery use. Removable refrigerated cases and their dedicated condensers may qualify in a grocery-anchored box, but a dry-goods store carries none of that package, and even in a grocery box the insulated walk-in envelope generally stays 39-year.
Is the loading dock a 15-year land improvement?
The equipment on it can be shorter-lived — dock levelers, seals and bumpers may qualify as 5-year property that serves loading operations. The structural dock slab, pit and framing generally stay 39-year, so the dock gets split by what's equipment and what's building.
How does bonus depreciation interact with a big-box study?
It accelerates the timing on property already sorted into 5- and 15-year pools, letting those take bonus in the placed-in-service year at the rate then in effect. Because so much of a big box's short-life value sits in the site, bonus tends to concentrate a large first-year deduction on the land improvements.
