Medical office cost segregation: $60K–$220K Year-1 deductions.
Specialty MEP — exam-room plumbing, gas lines, lead-lined imaging walls, sterile water — pushes medical office reclassification well above general office.
The 30-second answer
Medical office cost segregation reclassifies 30–38% of depreciable basis from the 27.5- or 39-year shell into 5-, 7-, and 15-year MACRS classes per 26 U.S.C. § 168 and Rev. Proc. 87-56. Under OBBBA's permanent 100% bonus depreciation (placed-in-service 2025+), reclassified components are deductible in year one. All credible cost-seg providers use the same federal framework — RSMeans 2026 cost data, MACRS classification, IRS Audit Techniques Guide (Pub 5653) compliance. What differs across property types is land-allocation share, FF&E weight, and material-participation eligibility under §469.
