In a distribution building the yard often matters more than the box. Cost Seg Smart models warehouses as a first-class type with a dedicated component library that captures the truck-court paving, dock equipment, material-handling infrastructure and refrigerated-warehouse equipment that a generic commercial template misses.
The signature fact: the dominant short-life line is usually the heavy-duty truck-court paving, and it scales with the paved yard area — not the building footprint. A low-coverage distribution box on a large truck court legitimately runs “hot.” The counterweight is discipline on the interior: building fire protection (interior ESFR sprinklers) generally remains 39-year, even though the underground yard fire loop and hydrants are 15-year site work.
What reclassifies in a warehouse
| Component | Recovery period | Basis |
|---|---|---|
| Dock equipment (levelers, seals, shelters, restraints); material-handling rough-ins | 5-year | Removable equipment serving the loading/handling function |
| Warehouse low-voltage, security, high-bay lighting controls | 5-year | Removable systems serving operations |
| Cold-storage refrigeration equipment (refrigerated warehouses) | 5-year | Removable equipment; the insulated envelope stays 39-year |
| Truck-court & trailer paving, yard lighting, drainage, fencing, monument sign | 15-year | Land improvements (paving scales with yard area) |
| Building shell, roof, interior ESFR sprinklers | 39-year | Real property (stays) |
Illustrative (modeled, not a completed client study). On a $5.0M distribution building with ~$4.2M depreciable basis and a large truck court, an accelerated share near the mid-20s percent would move well over $1M into 5- and 15-year pools. Actual results depend on site coverage, dock count and documentation, and on your CPA’s positions.
Cost Seg Smart produces warehouse studies using its dedicated engineering methodology, including the yard site-work analysis; per-property figures are produced at study time. Fees are published at costsegsmart.com.
