The least glamorous study on the table, sized honestly
A warehouse is deliberately simple: slab, structure, skin, roof, lights. That simplicity is why Engineered Tax Services reports 20% to 30% typical acceleration for warehouses, the low end of their published table, and any provider promising apartment-level percentages on a plain box is selling something. We would rather size it honestly: the percentage is modest, and the absolute dollars are frequently still excellent because industrial deals are big.
Where do the dollars hide? Outside, mostly. Truck courts, trailer parking, and yard paving at distribution scale are a serious 15-year pool, along with security fencing, gates, guard shacks, and site lighting. At the dock: levelers, seals, shelters, and door systems lean equipment. Inside: the electrical distribution sized for charging banks, conveyor and automation power, and compressed air serves equipment and allocates accordingly; office build-outs within the box reclassify like small offices.
The other honest point: much of a modern distribution center's cost is not the building at all. Racking, conveyors, sortation, robotics, and forklifts are equipment from their own invoices, 5- or 7-year property eligible for bonus or Section 179 with no study required. Keeping that layer out of building basis, and claiming it correctly, is often worth more than the study itself.
A 24% reclassification sounds unimpressive until it is 24% of a $18M basis. Warehouse studies clear their fees on absolute dollars and on the yard; screen them that way, and let the racking layer do its own work outside the study.
Where Warehouse Basis Actually Moves
The yard, the dock, and the power backbone.
| Component | MACRS life | Notes |
|---|---|---|
| Truck courts, trailer parking, yard paving | 15-year | The dominant pool at distribution scale |
| Security fencing, gates, guard structures, site lighting | 15-year | Land improvements |
| Dock levelers, seals, shelters, high-speed doors | 5-year | Dock equipment serving the operation |
| Electrical distribution serving chargers, conveyors, automation | 5-year | Allocated share of power backbone |
| Compressed air systems, battery charging infrastructure | 5-year | Equipment-serving utilities |
| Interior office build-out: finishes, cabling, break areas | 5-year / QIP | The office-within-the-box |
| Warehouse lighting (general), ESFR sprinklers, HVAC | 39-year | Building systems |
| Slab, structure, skin, roof | 39-year | The box itself |
Racking, conveyors, sortation, and mobile equipment are personal property from their own invoices and sit outside the building study entirely; do not let them be capitalized into building basis at construction.
Worked example (illustrative)
Regional distribution building, $18M basis
- Depreciable basis (excluding land and racking)
- $18,000,000
- 15-year: yard, truck courts, fencing, site lighting
- $2,700,000
- 5-year: dock equipment, allocated power, office fit-out
- $1,500,000
- Total accelerated (23.3% of basis)
- $4,200,000
- Year 1 deduction with 100% bonus
- ~$4,200,000 plus ~$354,000 straight-line
- Racking and automation (separate invoices, no study needed)
- Bonus/179-eligible on their own

Hypothetical case study
The 1031 buyer who studied only the delta
This is a hypothetical, illustrative composite, not an actual client or an actual result. Savings vary with your income, entity, state, and how usable the losses are.
A hypothetical investor completes a 1031 exchange out of an apartment building into an $18M distribution facility, carrying over substantial old basis. Only the excess basis (new money above the carryover) is fresh depreciable basis eligible for the full study treatment; the carryover continues its old schedule.
The study is scoped to the excess basis plus a classification review of the carryover schedule, in this hypothetical accelerating $1.9M of new-money basis rather than a naive $4.2M, and the fee is priced to the real opportunity. An unscoped study quoting the full building would have overpromised by more than half.
Hypothetical composite, not client figures. Exchange buyers should always tell the study provider about the 1031; the basis mechanics change the entire engagement.
The Industrial Owner's Stack
Racking, energy, and the tenant-vs-owner split.
- Racking and automation: 5- and 7-year property from invoices, bonus or Section 179 eligible, no study needed; the discipline is keeping installation and electrical tie-ins classified with the equipment they serve.
- Section 179D on warehouse LED conversions and HVAC: big flat roofs and high-bay lighting make industrial the classic 179D retrofit case.
- Rooftop solar carries its own credit and depreciation profile, coordinated with the building schedule.
- Net-lease investors: the passive gates (REPS, passive income) govern the study's usability, and tenant-owned trade fixtures stay off your schedule.
- Owner-users (3PLs, e-commerce operators) route the analysis through the self-rental and grouping rules when the real estate LLC rents to the operating company.
- Look-back studies on long-held industrial, where decades of yard paving sit inside 39-year basis.
Taxstra Tip
At construction or fit-out, give your GC a cost-code structure that separates yard, dock equipment, office fit-out, and equipment tie-ins. The classification you set in the draw schedule is the study you will not have to pay for later.
Delivering Warehouse Engagements
Scoped honestly, implemented completely.
We scope industrial studies against the honest range, coordinate the engineering through Engineered Tax Services, and keep the racking and automation layer claimed correctly outside the study. Taxstra implements schedules, Form 3115 look-backs, 179D coordination on retrofits, and the exchange-aware basis work for 1031 buyers.

What to check before you order a study
The pre-study review that decides whether the deduction is actually usable.
Separate racking, conveyors, and automation invoices from building basis from day one.
Measure the yard: paving scope drives the 15-year pool, and site plans price it quickly.
Disclose any 1031 carryover basis to the study provider before scoping.
Screen LED and HVAC retrofits for 179D alongside the study.
Confirm state bonus conformity for the building and each owner state.
Run the honest model in the cost segregation estimator before engaging.
