Why Common Areas & Unit Finishes Matter for Multifamily Investors
Common areas and individual unit finishes are the biggest missed depreciation opportunity for apartment building owners.
Lobby finishes, hallway improvements, laundry facilities, fitness centers, and individual unit fixtures are 5 and 15-year depreciable property — not part of the 27.5-year building. Most standard depreciation schedules treat everything as one bucket.
With bonus depreciation, eligible common area and unit components can be deducted in Year 1 — turning your property improvements into immediate deductions.
Multifamily properties typically have $30K–$120K+ in shorter-life components across common areas and units. Without cost segregation, those deductions are spread over 27.5 years instead of taken in Year 1.

Frequently Asked Questions
Cost segregation is an IRS-recognized depreciation method that reclassifies portions of your property into shorter depreciation categories (5, 7, and 15 years instead of 27.5). For multifamily investors, this means accelerating tens of thousands of dollars in deductions into the early years of ownership — reducing your taxable income significantly on apartment buildings, duplexes, and other multifamily properties.
Common areas that qualify include lobbies and entryways, hallway finishes, parking lots and garages, landscaping, exterior lighting, laundry facilities, fitness centers, pool areas, and mailroom fixtures. These are classified as 5, 7, or 15-year property — not part of the 27.5-year building structure — and can be depreciated on an accelerated schedule.
Yes. Duplexes, triplexes, and fourplexes all qualify for cost segregation at residential rates (27.5-year recovery period for the building). The same reclassification into 5, 7, and 15-year categories applies. Smaller multifamily properties often have a higher percentage of reclassifiable components per unit.
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.
Studies are delivered within 48 hours as a CPA-ready PDF sent to your email. Your CPA can use it directly — no additional formatting needed.
Yes. If you didn't do cost segregation when you bought the property, you can file a Form 3115 (Change in Accounting Method) to catch up on missed depreciation — without amending prior returns. The full catch-up amount is taken in a single year.
Yes. Our methodology follows the IRS Cost Segregation Audit Techniques Guide. Each study includes component-level analysis, IRS asset class citations, and supporting engineering narratives. We recommend all clients work with their CPA when filing.
