🇺🇸 Made in America·100% U.S.-Based Team · 24+ Years in Cost Segregation
An assisted living or senior housing community is a building and an operating business in one, and the business layer is where the depreciation sits: the commercial kitchen, the laundry, the emergency call system, the dining and lounge furnishings, the bathing rooms, the generator, and a site built for walkers and ambulances. By default all of it goes on the building's long schedule. A fully engineered and accounted cost segregation study separates what the engineering supports as 5-year, 7-year and 15-year property, and with 100 percent bonus depreciation that property comes out in the first year. Two catches come before the benefit. First, the building itself may be on 27.5 years or 39, depending on whether 80 percent of its rental income comes from dwelling units, and your CPA has to decide that before anything else. Second, if the real estate sits in one entity and rents to your operating company in another, the self-rental rules can leave the loss stranded. Settle those two and senior housing is one of the stronger property types for this work.
Vince ran a construction company in Green Bay, Wisconsin, for twenty years before he bought a 40-unit assisted living community on the east side of town in March 2025 for $6,000,000. He understood buildings, having built plenty of them, and he assumed the tax side worked like the warehouses and strip centers he had owned.
The community came with a commercial kitchen serving three meals a day, a laundry room with two commercial washers and dryers, an emergency call system wired to every unit and bathroom, a 150-kilowatt standby generator, two spa bathing rooms with lift tubs, a dining room and three lounges full of furniture, a therapy room, a covered drop-off canopy, 1,800 feet of accessible walkway, a courtyard, 48 parking spaces and landscaping designed so nobody trips.
His accountant put the whole $6,000,000 on one line, took out the land, and started depreciating the rest on one line.
Vince's instinct from twenty years of building things was that this made no sense. A commercial dishwasher and a concrete footing wear out on different clocks, and the tax code says so. Nobody had applied it to his property.
People treat senior housing as multifamily with older tenants. For depreciation, that framing misses most of what matters.
An apartment building is residential space plus common areas. A senior living community is residential space plus a commercial food service operation, plus a laundry operation, plus a care delivery system, plus hospitality space, plus a site designed around mobility and safety. Each layer adds equipment and improvements an apartment building never installs. More non-structural content means more that may qualify for faster recovery. It also means the analysis takes engineering judgment rather than a template.
Before any component is examined, the building itself has to be put on the right schedule, and on senior housing that is a real question.
Residential rental property depreciates over 27.5 years. Nonresidential real property depreciates over 39. One building is on one schedule, and the test is whether 80 percent or more of the building's gross rental income comes from dwelling units. A unit where most of the monthly fee pays for care, meals and services rather than housing is where the test gets hard. Independent living that functions like apartments usually passes. A skilled nursing facility delivering substantial medical care usually does not. Assisted living sits between, and the answer turns on how your fees are structured and what the residents are paying for.
That determination belongs to your CPA, and it affects the recovery period for the building itself before the study begins. It does not change what the study finds in the short-life property. The kitchen equipment is examined the same way whether the shell is on 27.5 or 39. If nobody has walked you through which schedule your building is on and why, that is the first conversation to have.
How any specific component is classified is an engineering and tax determination made on your building's facts, under the IRS Audit Techniques Guide and the tests the courts have set. These are the categories the analysis works through.
Food service and laundry operations. A commercial kitchen and a commercial laundry are business equipment, and the dedicated electrical, plumbing and ventilation that exist to serve that equipment rather than the building are examined with it.
Resident care infrastructure. Emergency call and monitoring systems, nurse call stations, and the wiring and devices that serve them exist because of the care operation. How they are installed and what they serve drives the analysis.
Furnishings and movable equipment. Dining rooms, lounges, activity rooms and therapy spaces are full of items whose attachment and permanence are the question. Movable items used in the operation are examined differently from things built into the structure.
Removable finishes serving appearance. Senior housing competes on how it feels. Decorative lighting, removable wall coverings, carpet, and decorative millwork exist for the resident experience, and that function matters.
Site improvements. Often larger than owners expect. Parking, drives, the covered drop-off, accessible walkways, exterior lighting, courtyards, fencing, signage and landscaping all sit outside the building, most of it examined as 15-year land improvement.
The structure stays the structure. Foundation, framing, roof, exterior walls, elevators, the main HVAC and the building's core electrical and plumbing recover on the building's schedule. Built-in kitchen and bath casework inside the units stays with the building too, because courts have treated it that way on dwelling units. A study that argues otherwise invites a challenge.
These numbers are illustrative and rounded. They use a 37 percent federal rate, and the actual split comes from the engineering. For this illustration Vince's CPA has confirmed the community meets the 80 percent test and is residential rental property.
At 37 percent, $1,696,811 of deduction is $627,820 of federal tax. The one-line version was $56,457. The difference in the first year is $571,363, on the same building with the same residents paying the same fees.
One cap sits on top of that, assuming the loss is nonpassive to Vince, which the next section covers. Vince and his wife file jointly, so Section 461(l) limits the net business loss he can deduct against wages and investment income to $626,000 for 2025 ($313,000 single; $512,000 joint and $256,000 single for tax years beginning in 2026, adjusted annually). The community's own operating income absorbs part of the deduction; whatever net loss remains above the cap carries forward as a net operating loss. He gets all of it, over two or three returns instead of one.
A fully engineered and accounted study on a qualifying property typically identifies $200,000 to $450,000 in additional first-year federal deductions per $1 million of depreciable basis. Senior housing lands in the middle to upper part of that range because of the operating layer, and the study determines where yours falls. If the building were on 39 years instead of 27.5, the building line in the first year would be $75,424 at the 39-year March rate of 2.033 percent rather than $106,811; the $1,590,000 would not change.
A first-year deduction is worth your tax rate only if you can use it in the year it lands, and senior housing owners run into the passive activity rules more often than other owners because of how the business is structured.
The common structure holds the real estate in one entity and the operating company in another, with rent between them. It makes sense for liability and financing. It collides with the self-rental rule in Reg. 1.469-2(f)(6): net rental income from property rented to a business you materially participate in is treated as nonpassive, but a net rental loss stays passive. A $1,590,000 depreciation loss in the real estate entity can end up stranded while the operating company pays tax on its profit.
There are two ways out, and both belong to your CPA. One is the grouping election under Reg. 1.469-4(d)(1)(ii), which can treat the rental and the operating business as a single activity when each owner holds the same proportionate interest in both, so the depreciation offsets the operating income. The other applies when the real estate and the operation sit in the same entity and the owner provides substantial services to residents; an activity where extraordinary personal services are provided is not a rental activity at all under Reg. 1.469-1T(e)(3)(ii)(C), and an owner who materially participates has a nonpassive loss. Which one applies, or whether neither does, depends on your structure, your participation and your other income. Ask before the study is ordered, while the grouping can still go on a timely filed return.
Senior housing is never finished. Units get refreshed as they turn, and memory care wings get reconfigured as the care model changes. A community operating for a decade has usually spent a large fraction of its original cost again, in pieces.
Most of that spending lands on the schedule as one more capitalized line on the building's long life, and a good deal of it replaces something still being depreciated. When flooring is replaced through a wing, the old flooring had remaining basis on the books. The partial disposition election under Reg. 1.168(i)-8 lets you write off the remaining cost of what you removed in the year you removed it, and deduct the cost of tearing it out, instead of stacking replacements on top of ghosts. As a rule the election is made on that year's timely filed return, with a late election allowed only in narrow cases, and it only works if the property was broken into components in the first place. You cannot write off what you never separately identified. On a community that renovates continuously, the recurring benefit over a holding period can rival the first-year deduction.
Keep the invoices. Unit-turn contractors, the kitchen equipment vendor, the flooring installer, the call-system integrator: those invoices document actual component costs, and they are the strongest support a study can have.
Vince bought an existing community and the study had to work backward from one purchase price. An operator who builds a 60-unit community for $14,000,000 is in a better documented position. The schedule of values, the monthly pay applications, the subcontracts for the mechanical, electrical, kitchen and site packages, the change orders and the closeout breakdown say what every component cost, written by unrelated parties at the time.
Developers purge those files within a few years. If you are building, tell your accounting team and your general contractor the cost detail is being kept for tax. One more point for builders: direct construction cost goes into basis, and so do indirect costs and construction-period interest that the capitalization rules require, so a developer's depreciable basis is usually larger than the hard-cost contract. Those soft costs get allocated across the components, and getting that allocation right feeds the study.
A software estimate that has never seen a care operation treats your community as a generic building and assigns a percentage. It cannot tell an examiner which circuits serve the kitchen and which serve the hallway lights, which is the question the examiner asks. A fully engineered and accounted study works component by component under the first two approaches the IRS Audit Techniques Guide describes: Approach 1, detailed engineering from actual cost records, and Approach 2, engineering with documented estimates reconciled to actual cost. The output is a component schedule your CPA imports and an examiner can trace, signed by credentialed professionals. It also records the original cost of every component, so each future renovation has a disposition number waiting. Cost Seg America defends it for as long as you own the building, no time limit, no hour cap, no additional fee, with written responses and participation in examiner calls alongside your CPA.
Treating it as multifamily. The operating layer is what separates senior housing from apartments, and it is where most of the deduction sits. A study built on an apartment template misses it.
Never confirming the recovery period. The 80 percent test decides whether the building is on 27.5 or 39, and the answer is fact-driven. If nobody has explained yours, ask.
Ordering the study before checking usability. A stranded passive loss is still real, but it is worth less, and the grouping decision has to be made on a timely filed return.
Discarding renovation records. Communities renovate constantly, and those invoices are both the best documentation for the study and the key to the partial disposition election.
Assuming the operating equipment was already handled. Usually it was swept into the building basis at acquisition and never separated. Check rather than assume.
A small residential care home in a converted house, with under $180,000 of depreciable basis after land, has limited basis and a thin operating layer; the fee can swallow the benefit.
An owner planning to sell within a year or two faces recapture: ordinary income under Section 1245 on the 5-year and 7-year property, and unrecaptured Section 1250 gain at up to 25 percent on the rest. On a short hold the recapture can outweigh the time value of the deduction.
An owner whose loss will be passive and who has no passive income to absorb it, and no grouping available, banks a carryforward. The deduction is real, but the delay costs money.
A community owned for fifteen years with no renovations has less remaining basis to analyze, though the renovation history usually changes that.
The proposal is free so you learn which of these describes you before spending anything. Declining a property where the numbers do not work is part of the job.
Yes. Senior housing carries a heavy layer of operating equipment, finishes and site work on top of the shell, and by default all of it sits on the building's long schedule.
It depends on the 80 percent gross rental income test. If 80 percent or more of the building's rental income comes from dwelling units, it is residential, 27.5 years. If the fees are mostly for care and services, it may be nonresidential, 39 years. Your CPA makes that call on your facts.
Commercial kitchen and laundry equipment serving the operation, and the dedicated connections that exist to serve it, are examined as business equipment rather than building. The recovery period for any item is determined by the engineering on your property.
The built-in casework and the plumbing in resident units stay with the building. Removable finishes like carpet and the movable appliances are examined separately.
Only if the loss is nonpassive or you have passive income. Where the real estate rents to an operating company you materially participate in, the self-rental rule keeps a loss passive unless a grouping election under Reg. 1.469-4 applies. Raise it with your CPA before ordering the study.
Yes, twice. The renovation spending is itself analyzed, and the old components you removed can be written off under the partial disposition election in the year of removal, if the property was broken into components and the election is made on that year's return.
No. The missed depreciation is caught up on your current-year return through Form 3115 and a Section 481(a) adjustment, at the bonus rate that applied when you placed the building in service. No amended returns. Cost Seg America prepares the computation and, for a separate fee, the Form 3115; your CPA files it.
Then you have the actual cost of every component from the pay applications and subcontracts, which is the strongest position a study can be built on. Keep those records.
Memory care wings carry more security, monitoring and specialized finishes, and the fee structure is heavier on care, which pushes the 80 percent test toward nonresidential. The component analysis works the same way.
On a community this size an in-house analyst does a proper inspection. On smaller properties a live video walkthrough, or a guided photo and video checklist the owner follows with the team reviewing every frame, covers it.
Ask your CPA two questions: which recovery period is the building on and why, and has the operating equipment ever been separated from the building basis. Then send Jim Dougherty and his team the property address, the purchase price and date, the unit count and a sentence about the care level. You will get a free proposal within 24 hours showing the estimated first-year deduction, the method, the timeline and the fee. The study is delivered in 30 days, with rush available.
