Project Overview
A multifamily owner completed a CSSI cost segregation study, identifying assets eligible for accelerated depreciation. Through a detailed engineering analysis, a significant portion of building costs were reclassified from a 39-year depreciation schedule to much shorter recovery periods, putting money back in the owner’s pocket sooner.
Study Results
The detailed engineering analysis successfully reclassified 17% of the total building costs into accelerated depreciation categories:

Financial Impact
By accelerating depreciation on $15.3 million of the property’s cost basis, the study generated substantial first-year tax deductions and meaningfully improved cash flow. Through the identification of personal property and land improvements, the owner was able to take advantage of:
- Bonus depreciation eligibility on qualifying assets
- Accelerated depreciation schedules on shorter-life property
- Enhanced cash flow through reduced tax liability
- Proper cost basis documentation for future disposition analysis
Building Systems Documentation
The study also included thorough documentation of the property’s building systems, a valuable resource for making informed capitalize-vs.-expense decisions in line with IRS Tangible Property Regulations. This documentation gives property owners:
- Current replacement cost benchmarks for each building system
- Detailed asset inventories by depreciable life
- Support for partial disposition elections on future improvements
- Compliance with IRC Section 1.263(a)-3 requirements
Compliance & Methodology
The study was conducted in full accordance with:
- IRS Revenue Procedure 87-56 asset classification guidelines
- Modified Accelerated Cost Recovery System (MACRS) regulations
- IRC Section 168 property classification standards
- Tangible Property Final Regulations (Treasury Decision 9636)
All asset classifications were supported by site inspection, architectural plans, construction documentation, and established engineering cost analysis standards designed to withstand IRS scrutiny.
Why This Matters
This case study illustrates how multifamily owners can unlock meaningful tax savings through a properly executed cost segregation study. By identifying and reclassifying nearly $15.3 million in assets eligible for accelerated depreciation, the property owner captured significant first-year tax benefits, all while remaining fully compliant with IRS guidelines.
