Cost segregation for self-storage facilities
A self-storage facility is mostly pavement wrapped around a cheap shell, and the drive aisles usually cover two to three times the building footprint. That paving is the reliable part of the result. The roll-up unit doors are the contested part: they are commonly treated as equipment, and there is real authority pointing the other way, which makes the rationale behind a storage study worth reading before you pick a provider.

1What reclassifies in a self-storage facility
In a self-storage facility, cost segregation typically reclassifies 8–38% of depreciable basis out of the 39-year building shell into 5-, 7- and 15-year property (modeled central tendency near ~23%). The components that recur:
| Component | Recovery period | Authority carried (with caveat) |
|---|---|---|
| Drives, aprons & loading-lane paving | 15-year | Land improvements (Asset Class 00.3) — usually the single largest short-life line. Scales with paved site area, which for a drive-up facility is 2–3× the building footprint. |
| Roll-up storage unit doors | 5-year (contested) | Commonly treated as Asset Class 57.0 property serving the identifiable rental-storage function rather than the building. Note the counter-authority: Reg. §1.48-1(e)(2) lists doors among structural components, and in McManus a hangar's doors were held §1250. The distinguishing argument is that a hangar door is the building wall, while a storage unit door encloses a rentable unit inside a shell that stands without it. A study taking this position should say so explicitly. |
| Climate-control HVAC (climate-controlled units) | 5-year (engineer review) | Split/PTAC units dedicated to conditioning rentable units may qualify as removable equipment serving the identifiable storage-unit function; a central system conditioning the building generally stays 39-year, and Reg. §1.48-1(e)(2) names HVAC among structural components. The building envelope stays 39-year either way. |
| Security, cameras, keypad & gate access | 5-year | Removable electronic security and access-control (Asset Class 00.12). |
| Movable corridor partitions, aisle lighting, wayfinding | 5-year | Demountable, non-structural systems serving the storage operation; partitions that are load-bearing or permanently affixed stay with the shell. |
| Rental-office FF&E, low-voltage & data | 5-year | Point-of-rental equipment and structured cabling serving the office function (Asset Class 00.12); a small line but routinely missed on facilities studied purely as a shell plus site. |
| Rental-office furniture | 7-year | Office furniture and fixtures fall in Asset Class 00.11 at 7 years, not the 5-year default that the rest of the office package carries. |
| Perimeter fencing/gates, site lighting, gate arm & call box, monument signage | 15-year | Land improvements (Asset Class 00.3); excavation and raw grading remain non-depreciable land. |
| Landscaping, irrigation, site drainage & detention | 15-year | Site land improvements (Asset Class 00.3). Detention basins and drainage are frequently omitted on storage studies even though the paved site that requires them is the property's largest short-life pool. |
2Typical results and what drives the spread
Our component engine models self-storage facilities directly, and its sanity band for this type runs 8–38% (central tendency near ~23%). Site coverage and climate control drive the spread. A multi-story climate-controlled facility on a tight urban lot sits well below a single-story drive-up facility on a large paved site, because the paving that carries the result is missing. Either way this is not a promise for any specific building — see by the numbers.

4What a study costs for this type
Study fees track building size, documentation quality and whether an on-site inspection is performed. A self-storage facility study typically runs in the $3.5k–12k range — an indicative band, not a quote, since the fee scales with depreciable basis. See the pricing guide for how Cost Seg Smart's fees scale by basis and which providers publish prices at all; most competitors are quote-only.

6Is it worth it — break-even
Because paving and doors concentrate short-life value, self-storage often accelerates well relative to a simple building. On a facility with meaningful depreciable basis, moving roughly a quarter of that basis into 5- and 15-year pools pulls deductions forward materially; the benefit generally clears a study fee once basis is in the low seven figures, earlier with bonus depreciation.
7Frequently asked questions
How much of a self-storage facility typically reclassifies?
Across standardized self-storage configurations our component engine models this type directly, and its modeling centres near 23%; the QC sanity band that flags an outlier study runs 8–38%. A single-story drive-up facility on a large paved site sits toward the high end because the paving dominates.
What drives the result in self-storage?
Site paving. A drive-up facility typically sits on two to three times its building footprint in drive aisles and aprons, so the 15-year paving pool is large relative to building square footage. Roll-up doors and access/security systems are the main 5-year lines.
Are the roll-up doors really equipment?
That is the open question in a self-storage study, and it is worth understanding rather than taking on faith. The common position, and the one most engineering-based providers take, is that per-unit roll-up doors serve the identifiable rental-storage function and are removable rather than load-bearing, so they are treated as 5-year §1245 property. The counter-authority is real: Reg. §1.48-1(e)(2) lists doors among a building's structural components, and in McManus v. United States the Seventh Circuit treated an airplane hangar's doors and partitions as §1250 property. The distinguishing argument is that a hangar door is the building's wall, while a storage unit door encloses a rentable unit inside a shell that stands perfectly well without it. Reasonable, but it is an argument, not a settled rule — so ask a provider to state the rationale in the report rather than simply booking the doors as equipment.
Is a site visit required?
It depends on the provider. Self-storage is highly repetitive and well-documented (unit counts, site plans), which makes a well-run virtual study feasible; some providers still require an on-site inspection.
What gets missed most often on a self-storage study?
Two things, both on the site rather than the building. The first is drainage and detention: a facility that is mostly pavement needs stormwater management, and those improvements are 15-year land improvements that get left out when a study treats the site as just the drive aisles. The second is the rental office, which carries its own small 5-year equipment and cabling and a 7-year furniture line under Asset Class 00.11 rather than the 5-year class most of the facility uses.
