High site-to-building ratio, significant gate systems — and a major panelized construction opportunity that software-based studies consistently miss.

Self-storage facilities have a characteristic that makes them disproportionately attractive for cost segregation: a very high ratio of site improvements to building value.
The asphalt. The gate access systems. The perimeter fencing. The exterior lighting. The stormwater infrastructure. These elements often represent 25–40% of total property value — and every dollar is 15-year land improvement property, fully deductible in Year 1.
The gate and access control system is the most overlooked item. Electronic gate mechanisms, keypads, cameras, intercoms, and card readers all qualify as 5-year personal property.
Then there is the panelized construction opportunity — where most studies fall short. Modern self-storage facilities built with panelized wall systems have interior partition walls that qualify as 5-year personal property. These are not structural walls. When properly engineered and documented, the panelized wall system is by far the largest single depreciation opportunity in modern self-storage — often representing 15–25% of the entire building value. Cost Seg America identifies and documents every qualifying panelized component.
These are the IRS-verified asset classes under Rev. Proc. 87-56 and supporting case law — confirmed across 16,000+ studies. Every component is documented to its correct recovery period with engineering justification, defensible under IRS examination.
Cost Seg America engineers self-storage cost segregation studies with specific attention to two opportunities that software models routinely undercount: the full site infrastructure as 15-year land improvements, and the panelized interior wall systems as 5-year personal property. The panelized wall opportunity is the single largest depreciation asset in modern self-storage construction. Our engineering team documents every qualifying panel.
The IRS publishes a 347-page Audit Technique Guide on cost segregation. It identifies Approaches 1 and 2 as the preferred methodologies. Studies priced under $2,900 recover $60,000–$150,000 less per $1 million of depreciable basis than a fully engineered study. Cost Seg America has used IRS Approaches 1 and 2 on every study for 24 years. 125+ IRS audits. Zero losses. $0 ever returned. The methodology is why.
Cost segregation is an IRS-approved engineering analysis that reclassifies components of your self-storage property from the default 39 yr straight-line depreciation schedule to three shorter recovery periods: 5-year personal property, 7-year personal property, and 15-year land improvements. Every component that qualifies for an accelerated schedule is individually identified, measured, and documented.
With 100% bonus depreciation active under OBBBA for property placed in service after January 19, 2025, every qualifying 5-year, 7-year, and 15-year component can be fully deducted in Year 1. Cost Seg America consistently recovers $60,000–$150,000 more in deductions per $1 million of depreciable basis than studies priced under $2,900.
The typical reclassification rate for self-storage is 20–35% of the depreciable basis. On a $6M property, this translates to approximately $528,000 in Year 1 federal income tax savings at a 37% rate. Actual results vary based on the specific property, construction type, and individual tax situation.
The One Big Beautiful Budget Act (OBBBA) restored 100% bonus depreciation for qualified property placed in service after January 19, 2025. With 100% bonus depreciation, every qualifying 5-year, 7-year, and 15-year component identified in your study is fully deductible in the year you place the property in service. Your CPA determines your eligibility based on your individual tax situation, passive activity rules, and other factors.
Yes. The IRS allows you to go back and claim deductions you never took on prior-year properties using a Form 3115 change in accounting method — without amending previous returns. The catch-up deductions are taken entirely in the current tax year. Cost Seg America applies lookback analysis as standard practice. We partner with a trusted CPA specialist who handles the Form 3115 filing.
Cost Seg America's minimum qualifying property value is $200,000. Below this threshold, the engineering cost typically exceeds the tax benefit. Above $200,000, the fee-to-benefit ratio is consistently favorable and grows substantially with property value.
Unlimited audit defense means if the IRS examines your cost segregation study — this year, five years from now, or ten years from now — Cost Seg America responds. Written responses and phone representation. No time limit. No hour cap. No additional fee. Ever.
In 24+ years and 125+ IRS audits, Cost Seg America has never lost an audit and has never returned a dollar to the IRS.
Cost Seg America doesn't just find the deductions — we document them to survive the most demanding IRS examination.
