Cost Segregation for Assisted Living and Senior Housing (2026)

Senior housing produces strong cost segregation results, commonly 25% to 35% of depreciable basis, because these buildings are dense with fixtures, specialty systems, and equipment that a conventional apartment building does not have.

But before any of that matters, there is a threshold question that changes the whole schedule: is the property residential rental property on 27.5 years, or nonresidential real property on 39 years? The answer depends on service level, and it is decided property by property.

Where the 27.5 Year Line Falls

Under IRC Sec. 168(e)(2)(A), residential rental property is a building from which 80% or more of gross rental income is rental income from dwelling units. The regulations exclude establishments where more than half the units are used on a transient basis.

Independent living communities generally qualify as residential rental property. Residents lease apartments, live independently, and pay rent. The 27.5-year schedule applies.

Skilled nursing facilities generally do not. Revenue is predominantly for medical and personal care services rather than for occupancy of a dwelling unit, and the facility functions as a healthcare operation. The 39-year schedule applies.

Assisted living sits between them and is genuinely fact dependent. A community where residents hold apartment leases and purchase care services separately looks residential. A community where a single all-inclusive fee covers heavy personal care, meals, and supervision looks nonresidential. The fee structure and the revenue breakdown are the evidence, so how the operator bills is a tax decision as much as an operations decision.

What Reclassifies Regardless of Schedule

Senior housing carries far more five-year property than conventional multifamily. Commercial kitchen equipment, walk-in coolers, dishwashing systems, laundry equipment, nurse call and emergency response systems, wander management and door monitoring, medication carts and dispensing systems, salon and therapy equipment, and dedicated generator and transfer switch capacity are all equipment.

Interior finishes contribute heavily too. Decorative and accent lighting, carpet and resilient flooring, millwork in dining and common areas, handrails and grab bars, window treatments, and appliances in resident units are five-year property.

Communities are also fixture-dense in a way that raises the count. A 96-unit assisted living building has 96 kitchenettes, 96 bathroom fixture sets, and a common area program with dining, activity, salon, therapy, and wellness spaces that a conventional apartment building simply does not have.

Site Work and Land Improvements

Fifteen-year land improvements run 8% to 13%. Senior communities require generous surface parking for staff and visitors, covered drop-off canopies, accessible walkways and ramps, resident courtyards and secured memory care gardens, walking paths, site lighting engineered for low-vision residents, fencing, and emergency generator pads.

Memory care courtyards are worth calling out because they are typically fully enclosed with substantial hardscape, secured gates, and specialty landscaping. This is a meaningful improvement package rather than incidental landscaping.

Worked Example: Assisted Living Community

An operator acquires an 88-unit assisted living community for $19,800,000. Land is allocated at $2,300,000, leaving $17,500,000 depreciable. The property bills an all-inclusive care fee and is classified as nonresidential on a 39-year schedule.

The study identifies five-year property of $3,850,000 (22%), seven-year property of $525,000 (3%), fifteen-year land improvements of $1,925,000 (11%), and 39-year structure of $11,200,000 (64%).

Reclassified basis of $6,300,000 is deductible in year one under IRC Sec. 168(k), plus $287,180 of structural depreciation, for approximately $6,587,180 against $448,718 on a straight 39-year schedule.

The Operating Business Advantage

Where the owner also operates the community, this is a trade or business rather than a rental activity. Personal care services are substantial, meals are provided, and staff are on site continuously. Under IRC Sec. 469 the analysis then turns only on material participation, and an owner-operator readily meets it.

That makes the deduction non-passive and usable against other active income. Where ownership and operations are separated through an operating company and a property company, the structure has to be built deliberately. The self-rental rules under Treasury Regulation Sec. 1.469-2(f)(6) can recharacterize rental income as non-passive without giving the corresponding loss the same treatment, which is exactly the wrong outcome. This structure should be reviewed before the study, not after.

Look-Back Studies on Stabilized Communities

Many senior housing owners built or acquired during a development wave and have been depreciating on a straight schedule for years. A look-back study with Form 3115 captures the entire missed deduction as a Sec. 481(a) adjustment in the current year, no amended returns required.

For a stabilized community that is now generating meaningful taxable income, this is often better timing than a study at acquisition would have been, when the property was in lease-up and generating losses anyway.

Frequently Asked Questions

Is assisted living 27.5-year or 39-year property?

It depends on the service model. Independent living generally qualifies as residential rental property at 27.5 years. Skilled nursing is generally nonresidential at 39 years. Assisted living is fact dependent, turning on whether 80% or more of gross rental income is rent from dwelling units under IRC Sec. 168(e)(2)(A).

Does the fee structure really change the depreciation schedule?

It can. Where residents hold apartment leases and buy care services separately, the rental income share is easier to establish. Where a single all-inclusive fee covers heavy care, the property looks less like residential rental. The billing model is evidence, so it deserves attention before it is set.

What percentage of basis typically reclassifies?

Senior housing commonly reaches 25% to 35%, higher than conventional multifamily. Commercial kitchens, nurse call systems, laundry, generators, salon and therapy spaces, and unit-level fixtures across dozens of units all add up.

Can I use the loss against my other income?

If you operate the community, yes. Substantial services make this a trade or business rather than a rental activity, so material participation under Treas. Reg. Sec. 1.469-5T controls. If you own the real estate and lease it to an operator, review the self-rental rules before assuming the answer.

I bought the community four years ago. Is it too late?

No. A look-back study with Form 3115 claims the full cumulative missed depreciation in the current year through a Sec. 481(a) adjustment. For a stabilized community now producing taxable income, this timing is often better than a study at acquisition.
