Why Tenant Improvements Matter for Office Investors
Tenant improvements and build-outs are the biggest missed depreciation opportunity for office building owners.
Custom build-outs, specialty lighting, data cabling, raised floors, and security systems are 5 and 15-year depreciable property — not part of the 39-year building. Most standard depreciation schedules miss these entirely. We break out every tenant improvement asset.
With bonus depreciation, eligible TI components can be deducted in Year 1 — turning your build-out costs into immediate deductions.
Office buildings typically have $50K–$200K+ in tenant improvements. Without cost segregation, those deductions are spread over 39 years instead of taken in Year 1.

Frequently Asked Questions
Cost segregation is an IRS-recognized depreciation method that reclassifies portions of your commercial property into shorter depreciation categories (5, 7, and 15 years instead of 39). For office building owners, this means accelerating tens of thousands of dollars in deductions into the early years of ownership — reducing your taxable income significantly.
Tenant improvements (TIs) include custom build-outs, specialty electrical and data cabling, dedicated HVAC zones, security systems, and modular partition systems. These are 5-year and 15-year depreciable property — not part of the 39-year building structure. Without cost segregation, these shorter-life assets are depreciated over 39 years, costing you tens of thousands in missed early deductions.
Yes — if you own the building. Cost segregation applies to the building owner, regardless of whether the space is leased to tenants. In fact, tenant improvements made by the building owner are some of the most valuable assets to reclassify. If you are a tenant who has made leasehold improvements, consult your CPA about depreciation options for your specific situation.
Just the basics: property address, purchase price, square footage, and year built. Our intake form takes about 5 minutes. No site visit required. Photos and documents (closing statement, tax assessment) are optional but can improve accuracy.
