Cost Segregation for Veterinary Clinics (2026 Guide)

Veterinary clinics reclassify at rates comparable to dental practices, generally 35% to 50% of build-out cost, and multi-doctor hospitals with surgery, imaging, and boarding run higher.

The reason is the same. A veterinary hospital is a distributed mechanical and equipment system that happens to sit inside a building, and the tax code classifies by function.

Kennel and Boarding Areas

Kennel runs, cage banks, gates and dividers, and the elevated flooring and drainage systems serving them are equipment rather than structure. Modern kennel systems are manufactured, modular, and removable, which supports five-year classification under IRC Sec. 168(e)(3)(B).

The dedicated mechanical serving these areas follows the same logic. High air-change ventilation, dedicated exhaust, and the specialized floor drains and trench drains installed for sanitation serve the kennel function rather than general building comfort, and under Treasury Regulation Sec. 1.48-1(e)(2) they classify with the function they serve.

Epoxy and seamless resinous flooring in kennel and treatment areas is a wear and sanitation surface applied over a structural slab. It is a finish, not a structural component.

Surgical and Treatment Suites

Surgical tables, lights, anesthesia machines and scavenging systems, monitoring equipment, autoclaves and sterilization, dental units, treatment tables, and wet tables with their dedicated plumbing are five-year property.

Medical gas systems, including oxygen and nitrous distribution, manifolds, and outlets, serve equipment rather than the building and follow the same treatment. Same for the dedicated vacuum and scavenging lines running to each treatment position.

Casework throughout treatment, pharmacy, and lab areas is generally equipment-grade fixture rather than site-built structural millwork, and classifies at five or seven years accordingly.

Imaging Rooms

Digital radiography, ultrasound, CT where present, and their dedicated power and data are five-year property. Lead shielding installed specifically to serve radiographic equipment can often be classified with that equipment, though the framing and drywall around it remain structural. This split should be documented rather than assumed in either direction.

Reception, Exam, and Retail

Exam room casework and tables, scales, computer and practice management hardware, sound masking, security and camera systems, decorative and accent lighting, resilient flooring and carpet, reception millwork, retail display fixtures, and signage are five-year property.

Clinics increasingly build retail and grooming areas, which reclassify like any retail fit-out. Display shelving, grooming tubs and their dedicated plumbing, dryers, and grooming tables are equipment.

QIP Covers the Structural Remainder

Most veterinary build-outs occur in existing nonresidential buildings. Interior improvements placed in service after the building itself generally qualify as qualified improvement property under IRC Sec. 168(e)(6), carrying a 15-year recovery period with full bonus eligibility.

That means new partition walls, ceilings, general lighting, and general HVAC in a leasehold build-out are recovered in year one under IRC Sec. 168(k) rather than over 39 years. Combined with the five-year personal property, a veterinary build-out is frequently close to fully deductible in the year it opens.

Worked Example: Multi-Doctor Hospital

An owner completes a 6,200 square foot hospital build-out for $1,480,000 in construction cost, plus $520,000 in medical equipment.

The study allocates construction to five-year property of $592,000 (40%), 15-year QIP of $814,000 (55%), and structural components not eligible for QIP of $74,000 (5%). All $520,000 of equipment is five-year property.

Under IRC Sec. 168(k), the five-year property, the QIP, and the equipment are all bonus eligible, producing approximately $1,926,000 of first-year deduction against a $2,000,000 total investment.

At a 37% marginal rate that is roughly $713,000 of federal tax reduction in the opening year, when a practice owner is typically carrying the heaviest debt service.

Owning the Building

Many veterinary owners buy the real estate through a separate entity and lease it to the practice. That building is its own cost segregation opportunity with its own study, typically reclassifying 20% to 30%.

The interaction matters. Under the self-rental rules in Treasury Regulation Sec. 1.469-2(f)(6), net rental income from a property leased to a business in which you materially participate is recharacterized as non-passive, but a net rental loss generally is not. A large first-year depreciation deduction in the property company can therefore create a suspended passive loss rather than a current deduction, which is the opposite of what most owners expect.

There are structural answers, including grouping elections under Treasury Regulation Sec. 1.469-4 where the requirements are met. This should be addressed before the study is commissioned, not after the return is filed.

Frequently Asked Questions

What percentage of a veterinary build-out reclassifies?

Typically 35% to 50% of construction cost to five-year property, with most of the balance qualifying as 15-year QIP. Multi-doctor hospitals with surgery, imaging, and boarding sit at the top of the range.

Are kennel runs five-year property?

Generally yes. Modern kennel systems are manufactured, modular, and removable equipment rather than structural components. The dedicated ventilation, exhaust, and trench drainage serving them follow the same treatment under the functional test in Treas. Reg. Sec. 1.48-1(e)(2).

Is epoxy flooring a structural component?

No. Seamless resinous and epoxy flooring applied over a structural slab is a wear and sanitation finish serving the clinical function, not a structural component. The slab beneath it is structure.

How are medical gas systems classified?

Oxygen and nitrous distribution, manifolds, outlets, and scavenging lines serve equipment rather than the building and are five-year property. The same applies to dedicated vacuum lines running to treatment positions.

I own the building through a separate LLC. Does that change anything?

Yes, significantly. Self-rental rules under Treas. Reg. Sec. 1.469-2(f)(6) can leave a large depreciation loss in the property company suspended rather than currently deductible. Grouping elections under Treas. Reg. Sec. 1.469-4 may solve it, but the structure should be reviewed before the study is run.
