What Is Cost Segregation for a Medical Office?
Cost segregation for medical office buildings reclassifies components from the standard 39-year commercial depreciation schedule into shorter recovery periods of 5, 7, and 15 years under the IRS Modified Accelerated Cost Recovery System (MACRS). Medical offices are among the highest-yielding commercial property types for cost segregation because of their specialized build-out requirements: exam rooms, procedure suites, sterilization areas, and medical-grade mechanical systems all contain components that depreciate far faster than the building shell.
The IRS treats medical office buildings as 39-year nonresidential real property by default. But a properly conducted cost segregation study identifies the portions of the building that are not structural and assigns them to the correct, shorter asset class. For a medical office, the density of specialized systems is significantly higher than a standard office building, which is why reclassification percentages are typically 30-42% of the depreciable basis.
With 100% bonus depreciation permanently restored for 2025 and beyond, every dollar reclassified into 5, 7, or 15-year property is deductible in the year of purchase or completion. On a $1.5M medical office, this can produce $150,000-$250,000+ in accelerated first-year deductions. Learn more about how bonus depreciation works in 2026.
Medical Office Components That Qualify for Accelerated Depreciation
Medical offices contain a dense concentration of specialized building systems that qualify for accelerated depreciation. These go well beyond the standard office finishes:
5-Year Property: Medical cabinetry and casework, exam room built-ins, reception desk millwork, specialized lighting (surgical lights, dental operatory fixtures), nurse call systems, patient monitoring wiring, interior signage and wayfinding systems, window treatments, decorative finishes in waiting areas, and carpet or luxury vinyl tile throughout non-clinical zones. Dental offices add operatory chairs, cabinetry, and suction/air systems as personal property.
7-Year Property: Lead-lined walls and doors for radiology suites, sterilization equipment, medical gas piping systems (oxygen, nitrous oxide, vacuum), specialized HVAC zones for procedure rooms and labs, backup generator systems dedicated to medical equipment, and data/telecom infrastructure for electronic health records.
15-Year Property: Parking lots and striping, patient drop-off areas, accessible ramps and sidewalks, exterior signage, landscaping and irrigation, perimeter lighting, and storm drainage. Medical offices in suburban locations with large surface parking lots can have 8-12% of their basis in 15-year improvements alone.
In total, medical office cost segregation studies typically reclassify 30-42% of the depreciable basis. Multi-specialty facilities with procedure rooms, imaging suites, or dental operatories yield the highest percentages because of the concentration of specialized mechanical and electrical systems within those spaces.
Why Medical Office Owners Order Cost Segregation Studies
Specialized build-outs generate above-average reclassification. A standard office might reclassify 25-35% of its basis. Medical offices routinely exceed that because of lead-lined walls, medical gas piping, procedure room ventilation, and specialized plumbing that all qualify for shorter depreciation lives. The more specialized the practice, the higher the reclassification percentage.
Physician-owners and practice groups benefit directly. Many medical offices are owned by the practicing physicians or a related entity. Cost segregation deductions flow through to the owners' personal returns, reducing taxable income from the practice or offsetting income from other investments. For physician-owned buildings, the tax savings often exceed the annual mortgage payment reduction from a rate drop.
Tenant improvements are separately depreciable. If you own the building and a medical tenant installed specialized improvements, those improvements may qualify for their own cost segregation analysis. Leasehold improvements placed in service by the building owner are depreciable over their MACRS life, not the lease term.
