Cost Segregation for Apartment Buildings

Apartment buildings — whether a 10-unit walk-up or a 200-unit garden-style complex — contain a significant amount of personal property and land improvements that qualify for accelerated depreciation. Without a cost segregation study, these components get lumped into the 27.5-year residential depreciation schedule, and you lose years of tax benefit.

What Gets Reclassified in an Apartment Building?

A cost segregation study identifies building components that qualify for 5-year, 7-year, or 15-year depreciation instead of the default 27.5-year schedule. In a typical apartment building, reclassifiable items include:

Unit interiors: Carpeting, vinyl flooring, cabinetry, countertops, appliances, window treatments
Common area finishes: Lobby fixtures, mailboxes, decorative lighting, fitness equipment
Site improvements: Parking lots, sidewalks, landscaping, fencing, retaining walls, exterior lighting
Mechanical components: Dedicated HVAC units, water heaters, laundry equipment
Security and access: Door entry systems, security cameras, gate operators

Example: A 50-unit apartment complex purchased for $5M might yield $1M–$1.75M in reclassified assets. With bonus depreciation, that translates to $250,000–$450,000+ in first-year tax savings.

Cost Segregation for Multifamily Syndications

If you invest in multifamily syndications, cost segregation is especially powerful. The accelerated depreciation flows through to investors as passive losses, which can offset passive income from other investments. For syndicators, it makes your deal more attractive to LPs who benefit from the front-loaded depreciation. Read more about cost segregation for multifamily properties.

Look-Back Studies for Existing Properties

Already own an apartment building? You can still capture accelerated depreciation through a look-back study. The IRS allows a Form 3115 change in accounting method that lets you claim all the missed depreciation in the current tax year — no amended returns required.

This is one of the most underutilized strategies in rental property tax planning.

When Does a Study Make Sense?

A cost segregation study is typically worthwhile for apartment buildings with a cost basis of $750,000 or more. The study cost ranges from $5,000 to $20,000 depending on property size and complexity, but the tax savings almost always exceed the investment by 5x or more.
