Cost Segregation in Westerville, Ohio

Westerville’s commercial growth has centered around suburban office parks, retail plazas, and mixed commercial developments. These properties often involve tenant build-outs, parking infrastructure, mechanical systems, and exterior site improvements that must be properly classified for depreciation purposes.


When office or retail properties are constructed, renovated, expanded, or acquired, construction-related costs require structured evaluation. A Cost Segregation analysis provides an engineering-based review to determine whether specific 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 Westerville.

Westerville’s Office and Retail Development Profile 

The Westerville market commonly includes:

Suburban office parks

Professional office buildings

Retail shopping plazas

Medical and service-oriented commercial buildings

Mixed commercial developments

Office park properties often contain interior tenant improvements, shared HVAC systems, lighting installations, and structured parking components. Retail plazas frequently include exterior paving, signage infrastructure, storefront build-outs, and common-area mechanical systems.



These features require technical evaluation to determine proper depreciation classification.


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

What a Cost Segregation Study Evaluates

A Cost Segregation Study reviews construction-related costs to determine whether certain building components may qualify for 5-, 7-, or 15-year recovery periods, instead of standard 27.5- or 39-year treatment.


RCG’s structured methodology typically includes:

Project Documentation Review 

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

Onsite Engineering Inspection

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

Engineering-Based Cost Allocation and 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 documentation and reconciliation.

Property Types Frequently Reviewed in Westerville

Property Category Components Commonly Evaluated Why Technical Review Is Necessary
Office Parks Tenant improvements, shared HVAC systems Multi-tenant spaces require structured allocation
Professional Offices Mechanical and electrical systems Interior build-outs often contain qualifying components
Retail Plazas Storefront build-outs, site improvements Exterior and common-area costs require classification
Medical Office Buildings Specialized interior systems Facility upgrades require technical evaluation
Mixed Commercial Projects Shared infrastructure components Combined-use properties require cost allocation analysis

Each property must be evaluated individually based on documentation and facility design.

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 based on 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 construction 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

“Retail properties have limited depreciation opportunity.”

Retail plazas often include site improvements and interior build-outs requiring structured engineering review.


“Office parks are fully 39-year property.”

Office properties frequently contain allocable components within tenant and mechanical systems.


“Cost segregation only benefits industrial buildings.”

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