Cost Segregation in Dublin, Ohio 

Dublin has developed into a high-value commercial real estate market characterized by office campuses, mixed-use developments, and technology-driven corporate facilities. These properties frequently involve substantial investment in tenant improvements, mechanical systems, structured parking, and exterior site infrastructure.


When office or mixed-use real estate is constructed, renovated, acquired, or expanded, construction-related costs must be properly evaluated for depreciation classification. A Cost Segregation analysis provides a structured engineering review to determine whether certain building components may qualify for shorter recovery periods under applicable tax guidance.


Since 2004, RCG has completed more than 25,000 R&D tax credit studies and identified over $750 million in tax savings. RCG applies the same documentation-focused and compliance-driven methodology to Cost Segregation engagements performed in Dublin.

Dublin’s Office and Technology Property Profile 

Dublin’s commercial base commonly includes:

Corporate office campuses

Technology-oriented office facilities

Mixed-use developments

Structured parking facilities

Retail and commercial components integrated within office projects

Office properties often include high-end interior build-outs, mechanical and HVAC upgrades, electrical infrastructure, and shared building systems. Mixed-use projects may combine retail, residential, and office components requiring layered cost allocation.


Technology-focused facilities frequently incorporate specialized electrical systems and infrastructure components that require engineering-based evaluation.



Each project must be analyzed individually based on documentation and physical characteristics.

What a Cost Segregation Study Evaluates 

A Cost Segregation Study examines construction-related costs to determine whether specific components may qualify for 5-, 7-, or 15-year recovery periods, rather than standard 27.5- or 39-year treatment.


RCG’s structured methodology generally includes:

Project Documentation Review  

  • Contractor payment applications
  • Construction invoices
  • Change orders
  • Depreciation schedules
  • Final cost summaries

Onsite Engineering Inspection

A physical inspection is conducted to evaluate building systems, operational use, and property configuration. Photographs of qualifying components are incorporated into the final report.

Engineering-Based Cost Reconciliation

  • Blueprint review when available
  • Quantity take-offs and cost estimation where required
  • Reconciliation of total project costs by tax life
  • Allocation of applicable soft costs
  • Preparation of a report aligned with IRS Cost Segregation Audit Technique Guide standards

The objective is proper classification supported by engineering analysis and documentation.

Property Types Frequently Reviewed in Dublin

Property Category Components Commonly Evaluated Why Technical Review Is Necessary
Office Buildings Tenant improvements, HVAC, electrical systems Office build-outs often require cost allocation
Mixed-Use Developments Shared mechanical systems, retail components Multi-use properties require structured classification
Technology Facilities Specialized electrical infrastructure Infrastructure may require engineering evaluation
Structured Parking Concrete systems, lighting installations Parking structures may include qualifying components
Commercial Developments Site work and common areas Exterior improvements may qualify for shorter recovery periods

Each property must be evaluated based on project-specific documentation.

Communities Served in the Dublin Market

RCG performs Cost Segregation analyses for properties located throughout the Dublin commercial corridor and adjacent business districts serving the northwest Columbus area.



These markets frequently support office expansion, commercial redevelopment, and mixed-use construction tied to the broader metropolitan economy.

Ohio Tax Considerations

Ohio income tax calculations begin with federal adjusted gross income but may include state-level modifications. Certain federal bonus depreciation deductions under IRC §168(k) may require adjustment under Ohio law.


Ohio’s Commercial Activity Tax (CAT) is measured by taxable gross receipts rather than net income. Accelerated depreciation generally impacts income tax liability rather than CAT liability.


Implementation decisions should be coordinated with a qualified CPA or tax advisor.

RCG’s Technical Approach

Engineering-Based Evaluation - Onsite inspections and engineering quantity take-offs support accurate asset classification decisions.

Documentation and Compliance Standards - A defensible Cost Segregation analysis requires proper classification, legal rationale, and reconciliation to actual project costs. RCG’s methodology aligns with IRS documentation expectations.

Experience in Technical Tax Services - Since 2004, RCG has completed more than 25,000 R&D tax credit studies and identified over $750 million in tax savings.

Common Misconceptions

“Office buildings have limited opportunity for cost segregation.”

Office campuses frequently include tenant improvements and infrastructure requiring technical evaluation.


“Mixed-use properties are too complex.”

Layered construction costs can be analyzed through structured engineering-based review.



“Only industrial facilities benefit.”

Eligibility depends on property type and cost basis, not industry classification.
