Self-Storage Cost Segregation: Buildings, Site Work and Equipment
By AE Tax Advisors · Published 2026-08-09 · Updated November 8, 2026.
A self-storage property can contain buildings, site improvements and equipment with different tax treatment. A reliable study identifies what was acquired or constructed and supports each classification. It does not begin with a required percentage to move out of the building category.
Reconcile land and development costs
Separate land from identifiable depreciable assets. Review site preparation, paving, drainage, fencing and utility work individually. The accounting label site work does not establish that every cost is depreciable or has the same recovery period.
Distinguish building functions from equipment
Document doors, partitions, climate-control systems, security, access controls, office fixtures and equipment by construction and function. A component serving the building generally can differ from one serving a specific piece of machinery.
Drive-up and climate-controlled facilities can have different asset mixes, but neither model establishes a universal allocation. Use plans, specifications and invoices for the property being studied.
Identify who owns improvements
Review lease terms, operator arrangements and tenant improvements. Avoid assigning the same asset to both a landlord and operator or treating leased equipment as an owned purchase.
Check the tax projection
Apply acquisition and service dates, bonus eligibility, elections and applicable loss limits. Operating the facility directly and leasing it to another operator can lead to different activity questions.
Compare the report cost, deductions currently usable, state adjustments and expected holding period. A large depreciation total is not itself proof of a positive return on the study.
Preserve component records
Keep the asset list for later expansion, roof or system replacement and sale allocations. Review recapture by asset instead of assuming the whole property receives one gain rate.
