Even a plain box reclassifies more than you’d expect.

The building may be four walls and a roof — but the truck courts, dock aprons, heavy power, and yard infrastructure around it typically move an estimated 10–25% of basis out of 39-year recovery.

What reclassifies

Walk the site, not just the building.

Warehouses look low on personal property — until you walk the site. Truck courts, dock infrastructure, heavy power, and yard work are where the recovery periods shorten, and on a big footprint the site work is usually the largest reclassified category.

The shell, roof structure, and general-purpose systems remain 39-year — the study separates them cleanly so everything labeled above can move.

About these figures. Representative example, not a client result. The square-footage leverage is the point: a lower percentage of a very large basis is still a large absolute number. Reclassification percentages are engineering estimates; year-1 figures are modeled tax estimates that depend on the §481(a) computation, the bonus rate for the placed-in-service date (2025 is a split year), state conformity, §469 passive-activity limits, and entity structure. Run the numbers with the §481(a) calculator or see a sample study at Cost Seg Smart. Ranges, not promises.

Questions

Asked by warehouse owners.

My warehouse is just a shell — is there anything to reclassify?

+

More than most owners expect. The building may be simple, but the site rarely is: truck courts, dock aprons, paving, fencing, yard lighting, and storm drainage are typically 15-year land improvements rather than 39-year building basis. On a large-footprint property, the site work alone is often the largest reclassified category.

What does “estimated” mean on the figures shown here?

+

Reclassification percentages are engineering estimates that vary by property, and the year-1 figure is a modeled tax estimate. What lands on a return depends on the §481(a) computation, the bonus rate for the placed-in-service date, state conformity, §469 passive-activity limits, and entity structure. A completed study and your CPA determine the final numbers.

Does it matter whether I own the racking and dock equipment?

+

Yes. A study reclassifies only what sits in your cost basis. Owner-owned racking, dock levelers, and process equipment can carry 5- or 7-year recovery; tenant-owned equipment belongs to the tenant’s schedule. The engineering takeoff documents ownership component by component, so only your basis is counted.

I bought through a 1031 exchange — does that change the study?

+

It changes the basis the study works from. A 1031 carries the relinquished property’s basis forward (carryover basis), often with an excess-basis layer from any new cash; the two are treated differently and that allocation affects how much accelerates. Your CPA confirms the treatment for your return, and tax-side figures remain estimates.
