Medical office buildings are packed with specialized construction, advanced utility systems, and extensive interior fit-outs. Because healthcare facilities require far more specialized infrastructure than standard office buildings, they are among the strongest candidates for accelerated depreciation of any commercial property type — often reclassifying a meaningfully higher share of their cost basis than a typical office building. A cost segregation study isolates these high-value components, allowing you to write them off faster and, under current bonus depreciation rules, potentially in full in year one.
At MVO Cost Segregation, we perform engineering-based studies for healthcare properties nationwide. Our team delivers clear property analyses and audit-ready documentation to build a depreciation strategy tailored to your exact facility.
In this article, we will break down why medical offices are perfectly suited for cost segregation, exactly how the underlying depreciation mechanics work, what different types of healthcare facilities can realistically expect to reclassify, the caveats worth understanding before you commit, and how MVO helps you maximize your immediate tax savings.
Why Medical Office Buildings Are Strong Candidates for Cost Segregation
Under standard IRS depreciation rules, a commercial medical office building is depreciated straight-line over 39 years using the Modified Accelerated Cost Recovery System (MACRS). Medical offices, however, require heavy-duty infrastructure that goes far beyond a standard office space. Healthcare facilities are packed with high-value, specialized assets, including dedicated electrical grids, medical gas plumbing, enhanced HVAC systems designed for infection control or medication storage, and reinforced flooring for heavy imaging equipment.
An engineering-based cost segregation study separates a medical office’s cost basis into the correct MACRS asset classes:
- 5-year property: Dedicated electrical circuits supporting medical equipment, isolated power systems, medical-grade plumbing connections, specialized HVAC components serving treatment areas, technology infrastructure (servers, HIPAA-compliant network systems), and certain casework and cabinetry.
- 7-year property: Office furniture, certain equipment, and other assets not otherwise classified.
- 15-year property (land improvements): Parking lots, sidewalks, exterior lighting, landscaping, and drainage systems.
- 39-year property: The core building structure — the shell, roof, structural framing, and general building systems that don’t qualify for a shorter life.
Through this engineering-based analysis, these specific upgrades can be isolated and fast-tracked for accelerated depreciation. This unique, specialized construction opens up tax-saving opportunities that simply don’t exist to the same degree with a traditional commercial office property — medical offices commonly reclassify a meaningfully higher percentage of their basis than standard office buildings, and facilities with imaging, surgical, or high-tech diagnostic buildouts can reclassify more still.
Healthcare facilities also tend to include extensive site improvements and interior build-outs that warrant a detailed review. Through Commercial Cost Segregation, engineering-based studies evaluate these assets individually to determine whether they qualify for shorter recovery periods under applicable IRS guidelines. This property-specific approach is especially valuable for cost segregation healthcare real estate because every medical facility is designed to support different specialties, patient services, and operational needs.
Every medical office is built differently, so generic assumptions do not work. A comprehensive, engineering-based study evaluates your specific construction and interior upgrades to identify every qualifying asset, ensuring your depreciation strategy perfectly aligns with your long-term investment goals.
How Bonus Depreciation Changes the Math in 2026
Cost segregation and bonus depreciation are two different tools that work together, and understanding the distinction matters for medical office owners planning their tax strategy.
- Cost segregation determines which assets can be reclassified into shorter recovery periods (5, 7, or 15 years instead of 39).
- Bonus depreciation determines how fast those reclassified assets can be written off once they’re in a qualifying class.
Under the Tax Cuts and Jobs Act, bonus depreciation was on a scheduled phase-down toward 20% by 2026 and full expiration by 2027. The One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, reversed that path: it permanently restored 100% bonus depreciation for qualifying property with a MACRS recovery period of 20 years or less, acquired and placed in service after January 19, 2025. The IRS issued Notice 2026-11 in January 2026 to clarify how the reinstated rule applies in practice.
For medical office owners, this is particularly meaningful because healthcare facilities typically carry a higher concentration of qualifying short-life assets than most commercial property types. A few mechanics to understand:
- The building shell itself doesn’t qualify for bonus depreciation. Only components with a recovery period of 20 years or less benefit from full first-year expensing. The core 39-year structure still depreciates on the standard schedule; only the assets a cost segregation study identifies and reclassifies benefit from bonus depreciation.
- The acquisition date matters. Property placed in service between January 1 and January 19, 2025 falls under the prior 40% bonus depreciation rate rather than 100%. Property placed in service after January 19, 2025 qualifies for the full 100% rate.
- Not every state conforms. States including California, New York, and New Jersey do not fully conform to federal bonus depreciation rules. A medical office in a non-conforming state may see the federal benefit without an equivalent state benefit, which should be modeled with your CPA.
- Frequent renovations create additional opportunities. Medical practices tend to update and expand their spaces more often than standard offices, which means there may be multiple layers of build-out costs, tenant improvements, and equipment upgrades that were never separately classified for depreciation purposes.
A Simplified Example: What a Medical Office Study Might Reclassify
The figures below are illustrative, not a guarantee — actual results depend entirely on the property’s specific construction and buildout. That said, applying the mechanics to real numbers helps explain why medical offices are considered one of the strongest healthcare property types for cost segregation.
Suppose a practice owner acquires or constructs a medical office building with a $2,500,000 depreciable basis (after subtracting land value), placed in service after January 19, 2025.
- Without cost segregation: The full $2,500,000 depreciates straight-line over 39 years — roughly $64,000 per year.
- With cost segregation: Standard office buildings typically reclassify somewhere in the 15%–25% range of depreciable basis. Medical offices, because of their specialized electrical, plumbing, and HVAC infrastructure, commonly reclassify a meaningfully higher share — often cited in the 25%–40% range, with facilities that include imaging, surgical, or dental operatory buildouts sometimes exceeding that. At 30%, that would move roughly $750,000 into the 5-, 7-, and 15-year classes.
- With 100% bonus depreciation: That $750,000 in reclassified assets can generally be fully expensed in year one rather than depreciated gradually, creating a substantial first-year deduction, while the remaining $1,750,000 continues on the standard 39-year schedule.
The actual percentage for any given practice depends on its specialty, buildout intensity, equipment infrastructure, and site improvements — which is why a property-specific engineering study, not an industry average, is the only reliable way to know your real numbers.
What a Medical Office Cost Segregation Study Evaluates
A medical office cost segregation study examines the property in detail to identify building components and site improvements that may qualify for shorter depreciation recovery periods. Rather than treating the entire building as a single asset, the study evaluates individual components based on their function, construction, and applicable IRS guidance.
Common assets reviewed during the study include:
- Specialized electrical systems that support medical equipment and treatment areas, including isolated power systems and dedicated circuits
- Medical plumbing serving exam rooms, laboratories, imaging suites, and specialty care spaces
- Dedicated HVAC systems designed for healthcare environments, including systems with enhanced filtration or pressurization
- Interior finishes, cabinetry, flooring, and partitions associated with medical operations
- Technology and data infrastructure supporting electronic health records (EHR), HIPAA-compliant networks, and telemedicine systems
- Parking lots, sidewalks, landscaping, exterior lighting, and other site improvements
- Security systems, access control, and additional infrastructure supporting daily operations
Medical building depreciation cost segregation relies on a detailed engineering review to determine how these assets should be classified for depreciation purposes. If you’d like to learn more about the methodology behind these evaluations, our guide on How Cost Seg Works explains how engineering-based studies identify qualifying assets while supporting accurate depreciation planning.
Because every medical office is designed differently, the assets identified will vary from one property to another. A property-specific analysis helps ensure the study reflects the facility’s unique construction and operational requirements.
Who Can Benefit From Cost Segregation?
Medical office buildings vary widely in design and use, which means the value of a cost segregation study depends heavily on the property’s specific characteristics and specialty. From single-provider clinics to large outpatient facilities, many types of healthcare properties may benefit from an engineering-based depreciation analysis.
Physician Offices
A cost segregation physician office study may be appropriate for privately owned medical practices — general practice, family practice, primary care, and urgent care facilities — with specialized treatment rooms, dedicated utility systems, custom cabinetry, and other improvements that support patient care.
Dental Offices and Dental Specialty Practices
Dental offices are frequently cited as one of the strongest healthcare property types for cost segregation, often reclassifying a comparable or higher percentage of building value than a general medical office. Dental operatory plumbing, delivery units, dedicated electrical circuits for imaging equipment, lead shielding in X-ray rooms, nitrous oxide delivery lines, and specialty cabinetry are all commonly identified and reclassified. This applies to general dentistry, orthodontic, endodontic, periodontic, and oral surgery practices alike.
Imaging and Diagnostic Centers
Imaging centers, radiology practices, and diagnostic facilities often carry some of the highest reclassification potential in healthcare real estate, driven by reinforced flooring, dedicated electrical infrastructure for MRI, CT, and X-ray equipment, specialized shielding, and enhanced HVAC.
Ambulatory Surgical Centers and Outpatient Surgery Facilities
Surgical centers typically involve extensive medical gas systems, specialized electrical and backup power infrastructure, enhanced HVAC and filtration, and reinforced construction — features that frequently support a higher reclassification percentage than a standard exam-room-based practice.
Urgent Care, Physical Therapy, and Rehabilitation Clinics
Urgent care centers, physical therapy practices, and rehabilitation clinics often include specialized flooring, equipment support systems, dedicated electrical, and treatment-area buildouts that may qualify for shorter recovery periods.
Dialysis Centers and Infusion Clinics
Dialysis and infusion facilities require dedicated water treatment systems, specialized plumbing, and backup power infrastructure that are frequently strong candidates for reclassification.
Multi-Tenant Medical Buildings
Buildings that lease space to multiple healthcare providers often include common areas, shared infrastructure, and tenant improvements that warrant a comprehensive engineering review. Each component is evaluated based on its function and applicable depreciation guidance.
Outpatient and Specialty Care Facilities
Urgent care centers, imaging facilities, surgical centers, rehabilitation clinics, and other specialty healthcare properties frequently contain specialized construction and equipment support systems. If you’re considering whether your facility may qualify, you can Estimate Your Savings to receive an initial evaluation based on your property’s details.
Every healthcare property has different construction features, improvements, and operational requirements. A professional evaluation helps determine whether cost segregation is appropriate and identifies the depreciation opportunities that best align with the property’s characteristics.
Important Caveats Before Moving Forward
Medical offices are among the most favorable property types for cost segregation, but that doesn’t mean a study is automatically the right move for every practice or every owner. The following caveats are just as important as the potential upside.
Depreciation Recapture on Sale
Accelerating depreciation defers tax liability — it doesn’t eliminate it. When a medical office building is eventually sold, the IRS may require depreciation recapture on gains attributable to previously claimed depreciation. Reclassified personal property (Section 1245 property) is generally recaptured at ordinary income tax rates, while the building structure itself (Section 1250 property) is subject to separate real property recapture rules, typically capped at a 25% rate. Because medical offices often reclassify a larger-than-average share of their basis, recapture exposure on sale can be more significant than on a comparable standard office property. This is worth modeling with your CPA before commissioning a study, particularly for practice owners planning to sell the building alongside the practice within a few years.
Passive Activity Loss Limitations
A large first-year deduction is only immediately useful if the owner can use it against taxable income in the current year. Under the passive activity loss rules, medical office owners who don’t materially participate in the property (for example, a physician who owns the building through a separate entity but leases it to their own practice) should confirm with their CPA how their specific ownership structure affects their ability to use the deduction immediately. Rules around self-rental and grouping elections can materially affect the outcome for physician-owned real estate specifically, and this is an area where the interaction between practice ownership and building ownership deserves careful tax planning.
State Tax Non-Conformity
Not every state follows federal bonus depreciation rules. Medical office owners in states that decouple from federal bonus depreciation, including California, New York, and New Jersey, may see a federal benefit that isn’t mirrored at the state level, which changes the overall economics of a study and should be modeled with a tax advisor familiar with the property’s state.
The Study Needs to Be Engineering-Based
Because medical offices commonly reclassify a higher percentage of basis than most commercial property types, they can also draw more scrutiny if the underlying study isn’t well documented. A study based on a rule-of-thumb percentage or a simplified software model carries meaningfully more audit risk than one built on a documented engineering review of architectural plans, mechanical/electrical/plumbing (MEP) specifications, contractor invoices, and a physical site inspection. The IRS has published audit guidance specific to healthcare and hospital properties in addition to its general Cost Segregation Audit Techniques Guide, underscoring how closely this property type is reviewed. An aggressive reclassification percentage without supporting documentation is one of the most common issues flagged on review.
Minimum Basis for the Study to Make Sense
Because a quality engineering-based study involves real time and expertise, it generally only makes financial sense once a facility’s depreciable basis reaches a meaningful threshold — commonly cited around $500,000 or more, depending on the provider and the complexity of the buildout. Below that range, the cost of the study can outweigh the incremental tax benefit. A qualified provider should be able to give you a realistic, property-specific estimate of both cost and expected benefit before you commit.

Frequently Asked Questions About Cost Segregation Medical Office
What is a cost segregation medical office study?
A cost segregation medical office study is an engineering-based analysis that identifies qualifying building components and site improvements that may be depreciated over shorter recovery periods (typically 5, 7, or 15 years instead of 39). This may allow eligible healthcare property owners to accelerate depreciation, and under current law, potentially fully expense those components in the year placed in service through 100% bonus depreciation, while complying with applicable IRS guidelines.
How much bonus depreciation can a medical office owner claim in 2026?
Under the One Big Beautiful Bill Act, 100% bonus depreciation is now a permanent feature of the tax code for qualifying property with a recovery period of 20 years or less, placed in service after January 19, 2025. Reclassified medical office components identified through a cost segregation study can generally be fully deducted in the year placed in service, subject to passive activity loss rules and state conformity issues.
Which medical office buildings are good candidates for cost segregation?
Many healthcare properties may qualify, including physician offices, dental practices, imaging and diagnostic centers, ambulatory surgical centers, urgent care and physical therapy clinics, dialysis centers, outpatient clinics, and multi-tenant medical office buildings. Eligibility depends on the property’s construction, improvements, and overall characteristics.
Do dental offices qualify for cost segregation, and are the savings different from a general medical office?
Yes. Dental offices are frequently among the strongest healthcare property types for cost segregation, often reclassifying a comparable or higher percentage of building value than a general medical office, due to operatory plumbing, imaging infrastructure, dedicated electrical systems, and specialty cabinetry.
What percentage of a medical office building’s basis typically gets reclassified?
Medical offices commonly reclassify a higher percentage of basis than standard commercial office buildings — often in the 25%–40% range, compared to roughly 15%–25% for a typical office. Facilities with imaging, surgical, or dental operatory buildouts can reclassify more still. The only way to know your property’s actual figure is through a property-specific engineering study.
What assets are commonly identified during a medical office cost segregation study?
A study may identify assets such as specialized electrical systems, medical plumbing, dedicated HVAC equipment, technology and data infrastructure, interior finishes, parking areas, exterior lighting, landscaping, and other site improvements. The assets identified vary based on each property’s design, specialty, and use.
Does depreciation recapture affect medical office cost segregation savings?
Yes. When a medical office building is sold, depreciation recapture rules generally apply to previously claimed depreciation. Reclassified personal property is typically recaptured at ordinary income rates, while the building structure is subject to separate real property recapture rules. Because medical offices tend to reclassify a larger share of basis than average, this is an important consideration for owners planning a shorter hold period.
Can a physician who owns their medical office building actually use the deductions right away?
It depends on the specific ownership structure. Physicians who own their building through a separate entity and lease it to their own practice should discuss self-rental rules, material participation, and grouping elections with their CPA, since these can significantly affect whether large first-year deductions are immediately usable or treated as passive losses.
Can an existing medical office building qualify for cost segregation?
Yes. A cost segregation study is not limited to newly constructed properties. Existing medical office buildings may qualify for a look-back study, which catches up previously unclaimed depreciation in the current tax year through a change in accounting method, without the need to amend prior returns.
How long does a medical office cost segregation study take?
The timeline depends on the property’s size, complexity, and the availability of construction and financial documentation. After reviewing the property, a qualified provider can provide a more accurate estimate of the expected timeframe.
Why choose an engineering-based cost segregation study?
An engineering-based study provides a detailed, documented evaluation of a property’s assets, including architectural plans, MEP specifications, and site inspection findings. This approach helps ensure qualifying assets are identified accurately and that the study reflects the property’s unique construction and operational features, in a way that holds up if the return is ever reviewed.
How do I know if my medical office building is a good candidate?
The best way to determine whether your property may benefit from cost segregation is through a professional evaluation. A qualified provider can review the building’s construction, improvements, asset composition, specialty type, depreciable basis, and ownership structure to determine whether a study aligns with your depreciation strategy.
