Self Storage Cost Segregation
The three positions our estimate uses for this property type, the components a study itemizes in the shorter lives, and an illustrative example from our estimate engine.
Conservative
10%
of building basis excluding land
Middle of the Road
15%

Aggressive
25%
of building basis excluding land
The shares our estimate uses for this property type. What the three positions mean
Expected reclassification range 22% to 42%, midpoint 32%
The comparative band for every property type is SmartCostSeg house judgment used to gauge an allocation against the type's own Conservative, Middle of the Road and Aggressive positions; it is not an IRS threshold, an industry percentile or a published median.
For this property type the Middle of the Road position sits below the expected reclassification range. The range is our comparative band for the audit risk gauge; the three positions are the shares the estimate uses.
The Conservative, Middle of the Road and Aggressive percentages for Self Storage are transcribed verbatim from the Expectation Guide row "Self Storage"; they are planning priors, not a substitute for documentation.
An Illustrative Example
Illustrative example computed by our estimate engine: purchase price $2,000,000, land $300,000 at the engine's default share of the price, acquired and placed in service January 1, 2026, so the engine applies a 100% bonus rate. The price and the land share are inputs for this example, not figures for this property type. Results vary with property specifics and your tax situation.
The estimate keeps the building on its 39 year life.
Building basis $1,700,000. First year depreciation without a study $43,590.
