Full or partial tear-offs on commercial and multifamily buildings.
Partial asset dispositions
Write off what you
tore out.
Replace a roof and most depreciation schedules keep depreciating the old one for another twenty years. The tangible property regulations let you dispose of it instead.
How it works.
A building is one asset for depreciation, but the regulations allow an owner to treat the retirement of a structural component, or a portion of one, as a disposition. The adjusted basis still sitting in the old roof, chiller, parking lot or windows becomes a loss in the year it is removed.
The election is made on the timely filed return for the year of the replacement, so it belongs in the same conversation as the repair-versus-improvement analysis. It also removes future depreciation recapture on the retired component when the property sells.
The hard part is the number. The original cost of a component that was never broken out has to be determined with a reasonable method, such as a producer price index discount or an engineering-based allocation. That is where a cost segregation approach does the work.
Who it fits
Chillers, rooftop units, panels, risers and fixtures replaced during renovations.
Parking lot reconstruction, lighting, fencing and landscaping.
Demolition of interior build-outs, storefronts and finishes.
What the engagement looks like.
- 01Identify the retirement
Confirm what was removed, when, and that the replacement was capitalized.
- 02Value the component
Determine the original cost and remaining basis with a documented, reasonable method.
- 03Reconcile the ledger
Remove the retired cost from the building record so no cost is depreciated twice.
- 04Coordinate the election
Provide the schedule and statement your CPA needs for the return.

Common questions
Before you start.
Every engagement begins with a free review of your facts. These are the questions we hear most.
What if the replacement happened in a prior year?
The elective disposition is tied to the timely return for the replacement year. Missed years need a different review; ask before assuming it can be recovered.
Does this conflict with expensing the work as a repair?
No. If the work is a deductible repair, there is no replacement asset and usually no disposition. If it is capitalized, the disposition applies. The two analyses go together.
Does it require a full cost segregation study?
Not always. A targeted valuation of the retired component is often sufficient; a full study is recommended when the renovation is large.
