Cost segregation for laboratories
A lab is a building organized around exhaust and process utilities. Fume hoods pull air out fast enough that the whole HVAC scheme bends to them; benches carry piped gases, deionized water and waste; floors and casework are specified for chemicals, not comfort. Most of that exists to serve identifiable bench processes and equipment — which is where the short-life value concentrates.

1What reclassifies in a laboratories
Cost segregation moves qualifying components out of the 39-year building shell into shorter recovery periods. In a laboratory the recurring short-life components are:
| Component | Recovery period | Authority carried (with caveat) |
|---|---|---|
| Fume hoods & lab exhaust — hoods, snorkels, exhaust fans, ductwork, VAV controls | 5-year | Dedicated process exhaust serving identifiable bench equipment and hoods generally follows that function rather than the building's general ventilation; general building HVAC stays 39-year. |
| Process gas & DI/RO water piping — specialty gases, deionized/reverse-osmosis loops | 5-year | Specialty piped utilities feeding identifiable lab equipment and benches may qualify as serving that equipment; domestic water and ordinary plumbing stay with the shell. |
| Dedicated once-through / high-exchange HVAC | engineer review | Air systems built for high air-change or non-recirculating lab operation can be arguable to the extent dedicated to process needs; the base-building comfort portion stays 39-year, so the split must be engineered. |
| Epoxy / chemical-resistant flooring & lab casework | 5-year | Non-structural specialty finishes and fixtures selected for process use generally reclassify; the structural slab and permanent building elements underneath remain 39-year. |
| Emergency power — generator, UPS to freezers/instruments | engineer review | Backup power dedicated to identifiable critical lab equipment can be arguable; capacity serving general building load stays 39-year, and the classification rests on a load allocation. |
| Eyewash, safety showers & specialty waste plumbing — acid-neutralization, sanitary dilution | 5-year | Safety and process-waste plumbing serving identifiable lab function generally qualifies; standard restroom and building drainage does not ride along. |
2Typical results and what drives the spread
Across standardized laboratory configurations, the engine models an accelerated share of roughly 20–40%. A wet lab dense with fume hoods, process gas and specialty waste lands high in the range; a dry or computational lab that is mostly bench and office sits lower. These are modeled ranges, not a promise for any specific building — see by the numbers.

6Is it worth it — break-even
Because so much of a lab is process infrastructure rather than shell, a modeled reclassification of 20–40% of depreciable basis is a credible planning band — a market range, not a promise. Front-loading that share into 5- and 15-year pools accelerates deductions by years; the benefit generally clears a study fee once basis reaches the low seven figures, and bonus depreciation, where available, deepens it. Wet, hood-heavy labs sit toward the top of the band.
7Frequently asked questions
Do the fume hoods and their exhaust really come out of the building?
The dedicated exhaust serving identifiable hoods and bench equipment is the strong part — it exists for the process, not general ventilation, so it generally follows that function. Shared makeup-air and comfort conditioning stay 39-year. The line runs between process exhaust and building HVAC, and an engineer draws it.
How is the lab HVAC handled if it's all one system?
By allocation. High air-change or once-through air has a process component that can be arguable and a comfort component that stays 39-year. When it's a single system, an engineer separates the dedicated capacity from the base-building capacity rather than the study claiming the whole thing.
Are the benches and casework worth reclassifying?
Generally yes — non-structural casework and chemical-resistant flooring selected for process use are classic 5-year candidates. What stays 39-year is anything structural or permanently integral to the building beneath them. The distinction is fixture-versus-structure, decided on the facts.
Does the type of lab change the outcome?
Significantly. A wet lab loaded with hoods, process gas and specialty waste concentrates far more short-life value than a dry or computational lab that is mostly bench, power and office space. That's why the modeled band is wide — the property type name alone doesn't fix the result.
We're a tenant in a research building — can we still do this?
Often, yes. A tenant who funded the lab fit-out generally holds the basis in those improvements and depreciates them, and qualified improvement property may have its own treatment. The study confirms who owns the improvements before classifying anything.
