Cost segregation for data centers
A data center is a shell wrapped around an extraordinary amount of power and cooling. This is a real-property study of the facility itself — the electrical distribution, standby generation, and mechanical cooling the building provides — not the servers, storage, or network gear a tenant or operator owns and depreciates separately. Because the base building is so infrastructure-heavy, the short-life share runs unusually high.
| Modeled reclass range | 38–60% |
|---|---|
| Typical study fee (Cost Seg Smart) | $4,995–$54,995 (sub-$100M); $100M+ by proposal |
| Recovery periods captured | 5-, 7- and 15-year vs the 39-year shell |
| Delivery | Engineering-based; virtual or on-site depending on the provider |
1What reclassifies in a data centers
Cost segregation moves qualifying components out of the 39-year building shell into shorter recovery periods. In a data center the recurring short-life components are:
| Component | Recovery period | Authority carried (with caveat) |
|---|---|---|
| Electrical distribution (switchgear, PDUs, busway) | 5-year | Distribution serving the identifiable computing load rather than general building power may qualify under Asset Class 57.0 / equipment treatment; the load it serves and how it is installed drive the outcome, so it depends on the facts. |
| Uninterruptible power supply (UPS) & battery plant | 5-year | Ride-through power dedicated to protecting connected equipment generally reads as machinery-supporting rather than building electrical; recovery depends on whether it serves the load or the structure. |
| Standby generators & paralleling gear | 5-year to 7-year | Emergency generation and switching tied to keeping the compute load online may qualify as equipment; a generator serving general building safety systems can read differently, so an engineer reviews the primary function. |
| CRAC/CRAH units & chilled-water cooling | 5-year | Process cooling that exists to remove heat from the servers, as distinct from human-comfort HVAC, generally supports the identifiable load; classification depends on what the system is designed to condition. |
| Raised access floor | 5-year | A structural-support access floor housing power and cooling distribution for equipment may qualify where it serves the systems rather than acting as the building floor; depends on installation and function. |
| Clean-agent fire detection & suppression | 5-year | Gaseous suppression protecting the equipment environment, beyond code-required life-safety, may be short-life; the portion tied to the building's base life-safety obligation is generally structural. |
| Building management & low-voltage systems | 5-year | Controls and monitoring dedicated to the mechanical/electrical plant serving the load may qualify; cabling and controls for general building operation are treated as structural — the served function governs. |
2Typical results and what drives the spread
Across standardized data center configurations, the engine models an accelerated share of roughly 38–60%. Power density (watts per square foot) and cooling architecture drive the spread more than square footage does. These are modeled ranges, 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. Cost Seg Smart's own fee for this type starts at $4,995–$54,995 (sub-$100M); $100M+ by proposal (published, pulled from its pricing system).

6Is it worth it — break-even
Because per-square-foot modeling overstates lightly loaded facilities, a defensible number comes from proportional, engineered basis reconciliation against the actual installed plant rather than a density assumption. These are engineer-signed studies offered by proposal; the reclassifiable share is generally modeled at 38–60% of depreciable basis, and at data-center basis levels the benefit clears a study fee comfortably, earlier still with bonus depreciation.
7Frequently asked questions
Does this study cover the servers and IT equipment?
No. Servers, storage, and network hardware are the operator's or tenant's personal property and are depreciated on their own schedule. This study addresses the facility — the base building's electrical, mechanical, and life-safety infrastructure — which is what the real-property owner depreciates.
Why is the reclassification percentage so high compared with an office building?
A data center's value is concentrated in power and cooling infrastructure rather than in the shell and finishes. Systems that serve the identifiable computing load may qualify for shorter recovery, and in a data center those systems dominate the basis, so the modeled range runs 38–60%.
Does it matter how densely the facility is loaded?
Yes, considerably. A partially populated or low-density facility carries less installed infrastructure per square foot, so a per-SF assumption tends to overstate its short-life share. That is why the reconciliation is engineered to the actual plant rather than a rule of thumb.
Can bonus depreciation apply to the reclassified assets?
Assets reclassified into shorter recovery periods may be eligible for bonus depreciation depending on the placed-in-service date and the facts of acquisition or construction. Your CPA confirms eligibility for your specific situation.
Is this a modeled estimate or an engineered study?
For data centers it is an engineer-signed, by-proposal study. The infrastructure is too specialized and too basis-significant to rely on a generic model; the analysis reconciles the installed electrical and mechanical plant to a supportable basis allocation.
