Medical office cost segregation: $95K–$485K 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 and dental office cost segregation is an engineering-based study that reclassifies a clinical office's components out of the default 39-year commercial schedule into faster 5-, 7-, and 15-year MACRS classes. A clinical office reclassifies far more than a plain office because the fit-out is dense with specialty infrastructure: exam and procedure casework, medical-gas distribution (oxygen, vacuum, nitrous, medical air), scrub sinks and specialty plumbing, dedicated imaging power and cooling, nurse-call and clinical low-voltage, and procedural lighting are all 5-year personal property when owned and documented. With 100% bonus depreciation the reclassified amount (about 16–23% of building basis, more when imaging and clinical equipment is documented) is deductible in Year 1.
Medical office cost segregation reclassifies 16–23% 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 — industry-standard 2026 construction 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.

Real examples
What medical office cost seg looks like in practice.
Estimates assume 37% federal bracket and full first-year usability of the loss (active income offset or REPS). Your actual benefit varies with bracket, basis allocation, and CPA's treatment.
Good fit when…
- ✓Owner-operator physicians or dentists who built out the suite
- ✓Medical office buildings with significant specialty MEP
- ✓Practices with imaging suites, sterile-area plumbing, or specialty lighting
Skip it when…
- ×Vanilla shell space leased to a medical tenant where you didn't pay for the build-out

Frequently asked
Medical office cost segregation, by question.
Do medical and dental offices qualify for cost segregation?
Yes — a clinical office reclassifies more than a plain office because the fit-out is dense with specialty infrastructure. Exam and procedure casework, medical-gas distribution (oxygen, vacuum, nitrous, medical air), scrub sinks and specialty plumbing, dedicated imaging power and cooling, nurse-call and clinical cabling, and procedural lighting are all 5-year personal property when owned and documented. A typical practice reclassifies roughly 16–23% of building basis, more when imaging and clinical equipment is documented.
Is medical gas piping and exam casework 5-year property?
Generally yes. Medical-gas distribution (oxygen, vacuum, medical air, nitrous) and specialty plumbing serve identifiable medical equipment rather than the building's general systems, and exam-room sink cabinets and procedure counters are removable trade-fixture casework — both typically depreciated over 5 years. The classification of any specific asset depends on its facts and is confirmed in the study.
Is imaging equipment like a CBCT or X-ray reclassified?
Yes, when you own it and it is documented — the equipment books as 5/7-year personal property, and the dedicated power, cooling, structural reinforcement, and mounts that serve an imaging suite are 5-year property because they serve identifiable medical equipment. It is captured only when the imaging suite and equipment are actually present and documented.
I lease my office and paid for the build-out — does it apply?
Yes, and often more strongly. A tenant who funded the clinical build-out depreciates that investment, and with no land or 39-year shell to strip out, a medical build-out reclassifies far more of its cost. That is handled as a tenant-improvement study on your build-out basis.
How much does a medical or dental office cost segregation study cost?
Medical and dental offices are priced as standard commercial property: from $1,995 for a sub-$1M basis and $3,295 for a typical $1M–$3M practice, delivered as a CPA-ready PDF in under an hour. No site visit required.
