What Is Cost Segregation for a Condo?
Cost segregation for condominiums reclassifies the interior components of your unit from the standard 27.5-year residential depreciation schedule into shorter MACRS recovery periods of 5, 7, and 15 years. The IRS permits this for any condo that is used as rental or investment property, whether it is a long-term rental, a vacation rental, or a short-term rental on platforms like Airbnb or VRBO.
Condos present a distinct cost segregation profile compared to single-family homes. Because you own only the interior of your unit (not the foundation, roof, exterior walls, or common-area structure), a larger share of your depreciable basis is concentrated in shorter-life personal property: flooring, cabinetry, countertops, appliances, and bathroom fixtures. The structural components that would normally dominate a single-family depreciation schedule are either excluded from your ownership entirely or represent a smaller fraction of the assessed value.
This means condo cost segregation studies often reclassify 20-30% of the depreciable basis into accelerated categories. With 100% bonus depreciation permanently restored under the One Big Beautiful Bill Act, every reclassified dollar is deductible in Year 1. On a $500K condo, that translates to roughly $25,000-$45,000 in first-year accelerated deductions depending on the unit's finishes, age, and furnishing level.
Condo Components That Qualify for Accelerated Depreciation
Because condo ownership is limited to the unit interior and a proportional share of common elements, the reclassifiable components are almost entirely interior finishes and personal property:
5-Year Property: Kitchen appliances (refrigerator, range, dishwasher, microwave, garbage disposal), carpeting and luxury vinyl plank flooring, cabinetry and countertops, bathroom vanities and mirrors, interior light fixtures, ceiling fans, window treatments (blinds, shades, curtains), closet systems, and in-unit laundry equipment. For furnished condos, all furniture, mattresses, linens, artwork, electronics, and kitchenware are also 5-year property, significantly increasing the reclassification total.
7-Year Property: Built-in shelving units, specialty plumbing fixtures (jetted tubs, steam showers), smart home systems, and removable wall coverings or accent walls.
15-Year Property: Your proportional share of land improvements maintained by the HOA, including parking areas, sidewalks, exterior lighting, landscaping, pool decks, and fencing, may be allocable to your unit. The portion attributable to your unit depends on the condo declaration and the number of units in the building.
Unfurnished condos typically see 20-25% reclassification. Furnished units used as short-term rentals can reach 28-35% because all furnishings, decor, and guest supplies qualify as 5-year property. High-end condos with upgraded kitchens, premium bathroom fixtures, and built-in closet systems also trend higher. See our guide to expected cost seg percentages by property type.
Why Condo Owners Order Cost Segregation Studies
Interior-heavy ownership favors reclassification. Since you do not own the building shell, a higher percentage of your depreciable basis is made up of shorter-life components. This makes condos more efficient for cost segregation on a per-dollar basis than many investors expect. The study isolates exactly which interior components qualify and assigns each one to the correct IRS asset class.
STR condos generate outsized benefits. Vacation rental condos that are fully furnished can reclassify all furniture, linens, kitchen supplies, and entertainment equipment as 5-year property. Combined with interior finishes, furnished STR condos often hit the top of the reclassification range. If you also meet the material participation requirements for short-term rentals, the resulting depreciation can offset W-2 and active business income.
Converted primary residences qualify. If you converted a condo from your primary residence to a rental, you can perform a cost segregation study as of the conversion date. The depreciable basis is the lesser of your adjusted basis or the fair market value at conversion, and the reclassified components begin accelerated depreciation from that point.
