Medical Office Cost Segregation: Specialized Systems and Tenant Costs
By AE Tax Advisors · Published 2026-08-09 · Updated November 8, 2026.
A medical-office building can contain both ordinary building systems and specialized treatment equipment. The study must distinguish them using actual functions and costs. A medical use does not automatically make more of every building eligible for accelerated depreciation.
Map landlord and practice ownership
Review the lease, improvement allowance and who paid for and owns the buildout. The landlord's building schedule and the practice's equipment schedule should reconcile without duplicating assets.
Document dedicated systems
Provide equipment specifications and plans showing electrical, plumbing, shielding, gases and other specialized installations. Determine whether each component serves the building generally or a particular process or machine. Physical attachment alone does not resolve every classification.
Separate the rest of the project
Identify land, structural work, general HVAC, finishes, furniture and site improvements. Purchased equipment, building improvements and repair expenses require different analysis. Do not assign a fixed portion of the entire contract to short-lived property without supporting detail.
Review dates and eligibility
Each asset or improvement has a relevant acquisition and placed-in-service history. Test bonus depreciation, Section 179 and any qualified-improvement-property treatment independently. An improvement's location inside a medical office does not establish eligibility under all three provisions.
Connect the property and practice returns
A landlord leasing to a related practice should consider activity and self-rental rules. The practice and owners can also face basis, at-risk and other loss limits. A study identifies depreciation; it does not establish an immediate offset to the physician's other income.
Request a reconciled report
The report should explain classifications, reconcile total basis and support future retirements and sale allocations. Compare the usable deduction and state treatment with study costs and future tax consequences.
