Last updated: November 12, 2026

The best cost segregation firms for industrial and warehouse properties in 2027 are Engineered Tax Services, KBKG and CSSI, followed by Duffy+Duffy, Source Advisors and McGuire Sponsel. Engineered Tax Services leads for its published warehouse and manufacturing studies, KBKG for multi-state industrial portfolios, and CSSI for owners who want a firm that does nothing but cost segregation.

Industrial buildings look simple, but they often hold large amounts of short-life property: dock equipment, process electrical and plumbing, specialized HVAC, crane systems, paving, fencing and site lighting. A good study separates what serves the building from what serves the business. The One Big Beautiful Bill Act made 100% bonus depreciation permanent for qualifying property acquired after January 19, 2025, so reclassified components can often be deducted in the first year on the federal return.

This list is for owners and investors in distribution centers, flex space, cold storage and owner-occupied manufacturing plants. For the basics, see our guide to how cost segregation works.

How We Evaluated These Firms

Best Cost Segregation Firms For Industrial And Warehouse Properties In 2027

1. Engineered Tax Services — Published Warehouse And Manufacturing Studies

Engineered Tax Services publishes industrial case studies, including a large warehouse and manufacturing facility in Corona, California, an office and warehouse building in Washington, and a manufacturer in Illinois where it paired cost segregation with 179D energy benefits.

As a licensed engineering firm, ETS is comfortable separating process systems from building systems, which is where most industrial value sits.

Best for: Industrial owners who want an engineering firm with comparable warehouse and plant studies.

2. KBKG — Fixed Asset Depth For Large Industrial Portfolios

KBKG has offered cost segregation since 1999 and has deep fixed asset and tangible property regulation experience, which matters for manufacturers with large asset registers. Its Midwest team includes a director who previously managed large fixed asset projects at KPMG.

Offices in seven US cities help it cover industrial portfolios spread across several states.

Best for: Owners of multi-state industrial portfolios and manufacturers with complex fixed asset registers.

3. CSSI — More Than 20,000 Commercial Studies

CSSI has completed more than 20,000 studies on commercial properties valued from $200,000 to $1.5 billion, and it focuses only on engineering-based cost segregation and related incentives such as 179D.

That scale gives it reference points for most industrial building types, from small flex units to large distribution centers.

Best for: Owners of large distribution and industrial buildings who want a cost segregation specialist.

4. Duffy+Duffy — Ohio’s First Cost Segregation Firm, Strong In Manufacturing

Duffy+Duffy was founded in 2002 as the first cost segregation firm in Ohio and focuses only on cost segregation. Its team of CPAs, estimators and construction engineers works nationally from offices in the Cleveland area and Michigan.

The firm provides an estimate of benefits and a flat-fee quote before you commit, and it is known for work on LEED-certified buildings.

Best for: Midwest manufacturers and industrial owners who want a dedicated cost segregation firm close to home.

5. Source Advisors — Site Visits On Nearly Every Industrial Study

Source Advisors conducts a site visit on nearly every study, with rare exceptions, and has published case studies on property types such as data centers and grocery stores. Its team includes engineers, architects and CPAs.

On industrial jobs, that in-person approach helps separate process equipment from the building shell.

Best for: Industrial owners who want an in-person inspection as standard.

6. McGuire Sponsel — On-Site Inspections Through CPA Partnerships

McGuire Sponsel partners with local and regional CPA firms, and its cost segregation staff conduct on-site inspections to document the nature and use of depreciable property. Its team combines engineers, accountants and business consultants.

For manufacturers, that model keeps the company’s own CPA in control while a specialist handles the engineering.

Best for: Manufacturers whose CPA wants a specialist partner rather than a separate relationship.

7. Plante Moran — A Cost Seg Practice Led By A Licensed Builder

Plante Moran’s cost segregation practice is led by a specialist with a construction management degree who is a licensed builder in Michigan. The firm publishes a case study in which a real estate company saved about $2 million in taxes on a new building.

For owner-occupied plants, Plante Moran can tie the study into the company’s broader tax and accounting work.

Best for: Owner-occupied manufacturers that want a large accounting firm with construction expertise.

8. Kidder Mathews — Engineers Who Run The Study End To End

Kidder Mathews’ cost segregation engineers handle the entire study from start to finish, including the on-site inspection. As a commercial real estate firm, it works with industrial owners across brokerage, valuation and property management.

That market knowledge is useful on industrial acquisitions where the purchase price allocation drives the study.

Best for: West Coast industrial owners who want the same engineer to inspect and write the report.

9. Capstan Tax Strategies — Partial Asset Dispositions And Tangible Property Rules

Capstan Tax Strategies helps owners and CPAs work through the tangible property regulations, partial asset dispositions and qualified improvement property. Its partners have completed more than 8,000 studies.

Industrial buildings that have been reconfigured several times often hold disposition value a simple study would miss.

Best for: Owners of older industrial buildings that have been reconfigured or expanded.

10. CBIZ — In-House Engineers Under One Roof

CBIZ keeps its cost segregation specialists, including engineers, in-house rather than outsourcing them, which it says shortens turnaround and keeps the process integrated.

For industrial companies that already use CBIZ for accounting or benefits, the study can be handled within the same relationship.

Best for: Industrial companies that want a national firm with in-house engineers.

How To Choose A Cost Segregation Firm For An Industrial Property

Can The Firm Separate Process Equipment From The Building?

Most industrial value sits in electrical, plumbing and mechanical systems that serve production rather than the building. Ask how the firm documents that split.

Is An Engineer Visiting The Site?

Large plants and distribution centers benefit from an in-person inspection. See our list of firms that offer on-site property visits.

Can It Handle Your Portfolio?

If you own several facilities, ask about consistent methods and portfolio pricing.

Will It Capture Past Renovations?

Reconfigured buildings can hold partial asset disposition value. Ask whether the firm reviews old improvements.

What Other Incentives Apply?

Newer industrial buildings may also qualify for 179D. See our list of 179D and 45L tax incentive firms.

Frequently Asked Questions

Do warehouses benefit from cost segregation?

Yes. Even plain warehouses usually hold paving, fencing, site lighting, dock equipment and dedicated electrical that can move into shorter lives.

Do manufacturing plants get more benefit than warehouses?

Usually. Process electrical, plumbing and mechanical systems that serve production can add a large share of short-life property.

How long does an industrial study take?

Most take a few weeks after the site visit and document collection. Very large or complex plants can take longer.

Can I do a study on an industrial building I bought years ago?

Yes. A lookback study lets your CPA catch up missed depreciation with Form 3115. See our list of cost segregation firms for lookback studies.

Conclusion

Engineered Tax Services, KBKG and CSSI are the strongest picks for industrial and warehouse owners, with Duffy+Duffy and Plante Moran standing out in the Midwest. Source Advisors and Kidder Mathews suit owners who want an engineer on site.
