Medical Office Cost Segregation: Buildouts & Ownership

Updated October 9, 2026 · Stratum Cost Segregation · Editorial policy

Review medical office cost segregation with a focus on equipment connections, tenant improvements, ownership, project costs, and CPA coordination.

Start with the owner and the building's use

A medical practice and the owner of its office can be different taxpayers. Identify the legal owner, tenant, equipment owner, and party paying for each improvement before assembling a study. Nonresidential real property generally has a 39-year GDS recovery period. That starting point does not make all costs in a medical office building structural, nor does a clinical use automatically make them short-lived.

Distinguish equipment support from general building systems

Map examination rooms, imaging rooms, laboratories, sterilization areas, reception space, and shared circulation. For each specialty installation, record what it serves and what would remain if the equipment were removed. Dedicated equipment connections can require a different analysis from the building's general electrical, plumbing, or HVAC systems. Supply drawings and contractor detail; a description such as medical plumbing does not establish a tax classification.

Reconcile tenant improvements and landlord allowances

Keep the lease, work letter, allowance agreement, change orders, invoices, and payment records together. Create separate columns for the party contracting for work, the payer, reimbursement, and the person treated as owner for tax purposes. Ask the preparer to resolve those facts. Do not count the same buildout in both the landlord's and tenant's cost schedules simply because both have records of it.

Review qualified improvement property separately

Some interior improvements to an existing nonresidential building may meet the qualified improvement property definition. The rules exclude specified categories and have timing requirements. Ask the preparer to distinguish eligible interior work from original construction, enlargement, structural framework, and elevator or escalator work. Keep acquisition and construction dates separate from the date the practice opened.

Use a project map before a tax projection

Consider an illustrative practice that pays one contractor for exam rooms and reception, and another vendor for imaging equipment. Begin with the final invoices and supported ownership. Ask whether the first invoice can be separated into actual scopes and whether the equipment installation overlaps with those charges. Resolve duplicate costs and allowance reimbursements before applying any depreciation assumptions. This is a documentation example, not a deduction estimate.

Coordinate the property and practice tax reviews

If a related entity rents the office to the practice, flag that relationship for the preparer. A cost segregation study alone does not establish whether a loss can offset practice earnings. Ask for a written analysis of the relevant activity rules, basis, elections, and state adjustments. For a study proposal, request the component methodology, excluded costs, supporting evidence, delivery schedule, and responsibilities for implementing the final report.

Medical offices: identify landlord and practice-owned assets

Collect leases, buildout agreements and equipment schedules. Distinguish the building owner’s investment from the medical practice’s separately owned equipment and tenant improvements. Document the function of dedicated installations and ordinary building systems before proposing treatment.

A fictional scope example

A physician owns the real estate through one entity and operates the practice through another. Match each invoice to the payer, tax owner and underlying asset. A payment from the practice account does not by itself determine who owns a building improvement.
