Qualified Production Property Under Section 168(n): Why Most Landlords Cannot Claim It (and Who Can)
A New Depreciation Category for Manufacturing Real Estate
The One Big Beautiful Bill Act created a brand new asset class that did not exist before 2025: qualified production property, or QPP, under IRC Section 168(n). On February 20, 2026, the IRS issued Notice 2026-16 to provide the first substantive interim guidance on how the provision actually works. Because the notice is new and the rules are unusually generous, a lot of loose talk has started circulating in real estate investing circles suggesting that any landlord who owns industrial or warehouse space leased to a manufacturing tenant can now write off the entire building in year one.
That is not what the statute says, and it is important that rental property investors understand the difference before they build a tax strategy around a misunderstanding. Section 168(n) is genuinely one of the most powerful depreciation provisions Congress has enacted in years, but it was built for owner-operators of manufacturing facilities, not for passive landlords collecting rent from a tenant who happens to manufacture something. This article walks through what QPP actually requires, why the original use rule blocks most conventional landlord arrangements, and the narrower set of situations where a rental property investor can genuinely use it.
What Counts as a Qualified Production Activity
QPP is defined as nonresidential real property that is used by the taxpayer as an integral part of a qualified production activity, or QPA. A QPA generally means manufacturing, production, or refining of tangible personal property where the process results in a substantial transformation of the property. Think of a metal fabrication plant turning raw steel coil into finished components, a food processor turning agricultural inputs into packaged products, or a chemical manufacturer converting raw feedstock into a different chemical product.
Activities that do not rise to the level of substantial transformation generally do not qualify. Simple assembly of already-finished components, packaging, labeling, or minor processing that does not fundamentally change the nature of the product typically falls outside the definition. Office space, showrooms, retail areas, and administrative functions within an otherwise qualifying facility are also excluded from QPP even when they sit inside the same four walls as a production line, because those areas are not themselves used in the qualified production activity.
This is a meaningfully narrower category than most of the industrial and flex-space inventory that rental property investors typically buy. A self-storage facility, a distribution warehouse that receives and ships finished goods without transforming them, a cold storage facility, or a light industrial building used for equipment repair generally will not meet the substantial transformation standard on its own.
The Original Use Rule That Trips Up Landlords
Here is the provision that matters most for anyone reading this as a rental property investor rather than a manufacturer. Section 168(n) requires that the original use of the property in the qualified production activity begin with the taxpayer claiming the deduction, and the statute explicitly provides that property used by a lessee is not treated as used by the taxpayer for this purpose.
In plain terms, if you own an industrial building and lease it to a tenant who runs a manufacturing operation inside it, you as the landlord cannot claim the Section 168(n) deduction on that building. The tenant is the one conducting the qualified production activity, not you, and the statute was written specifically to prevent the deduction from being claimed by a party who is not the one operating the qualifying activity. This is a sharp departure from how bonus depreciation under Section 168(k) and a conventional cost segregation study work, where a landlord can fully benefit from accelerated depreciation on components regardless of what the tenant does with the space.
This single rule eliminates the most common scenario that gets pitched informally: buy a warehouse, lease it to a manufacturer, and expense the building. It does not work that way under the current guidance, and any advisor telling you otherwise is either misreading the statute or is not accounting for the leasing carve-out that Notice 2026-16 reaffirms.
Where the Real Opportunity Lives: Related Parties and Self-Occupied Real Estate
The original use rule does not eliminate QPP for real estate investors entirely. It narrows the opportunity to structures where the entity claiming the deduction is functionally the same economic party as the one operating the production activity.
The most common fact pattern we see is the business owner who holds real estate in a separate LLC for asset protection and liability reasons, then leases the building to their own operating company. If the operating company is engaged in a genuine qualified production activity, and the ownership and lease structure meets the related-party standards that Notice 2026-16 and subsequent guidance address, the original use requirement can be satisfied because the taxpayer group as a whole is both the property owner and the operator of the production activity. This is a materially different situation from an arm's length lease to an unrelated tenant, and it requires careful structuring with your CPA and tax attorney to get right, including attention to related-party depreciation rules under Section 267 and consolidated group considerations where applicable.
The other clear case is straightforward owner-occupied real estate. If you are constructing or acquiring a facility that your own business will use directly for manufacturing, and you hold title to the real estate yourself rather than leasing from an unrelated landlord, the original use requirement is naturally satisfied. This is common among manufacturers who are also real estate investors in the sense that they own their operating facility outright.
The 95% De Minimis Rule for Mixed-Use Facilities
Most real production facilities are not 100% production floor. There is office space, a break room, a loading dock, and often a showroom or shipping department. Notice 2026-16 addresses this with a de minimis rule: if 95% or more of the physical space within a building is used for qualifying production activities, the taxpayer can elect to treat the entire building as QPP, including the portions used for non-qualifying purposes like offices and administrative space.
This threshold is high. A facility with a modest front office and a large production floor can often clear 95%, but a building with a substantial showroom, significant warehousing of finished goods for shipment, or a meaningful administrative footprint may fall short. Measuring this accurately requires the same kind of engineering-based square footage analysis that a cost segregation study relies on, and getting the measurement wrong in either direction creates real risk: understating the qualifying percentage leaves money on the table, while overstating it creates exposure on audit.
Timing: Construction Start and Placed-in-Service Windows
QPP has its own timing rules that are separate from the general bonus depreciation windows under Section 168(k). Construction on the property must begin after January 19, 2025, and before January 1, 2029. The property must then be placed in service after July 4, 2025, and before January 1, 2031. Property that does not fall within both windows does not qualify for the Section 168(n) deduction, regardless of how clearly it otherwise meets the production activity and original use tests.
These dates matter for planning purposes if you are in the process of developing or acquiring a facility for your own manufacturing operation. A project that broke ground before the window opened, or that will not be placed in service until after the window closes, needs a different depreciation strategy, most likely a conventional cost segregation study paired with standard bonus depreciation under Section 168(k) on the components that qualify.
How QPP Interacts With a Traditional Cost Segregation Study
It is worth being precise about what makes Section 168(n) different from the cost segregation studies Stratum performs every day. A standard cost segregation study identifies the portion of a building's cost that qualifies as tangible personal property or land improvements under Sections 1245 and 1250, typically 20% to 35% of the depreciable basis, and applies accelerated MACRS recovery periods and bonus depreciation to those components. The structural shell of the building itself, which normally depreciates over 27.5 or 39 years, is excluded from bonus treatment entirely under ordinary rules.
QPP changes that equation dramatically, but only for the narrow category of property that qualifies. If a building meets the QPP definition, the structural components themselves become eligible for the 100% special depreciation allowance, not just the personal property and land improvements a traditional study identifies. That is a fundamentally larger deduction, because it reaches the largest cost category in almost any building: the shell, roof, and structural systems.
For taxpayers who do qualify, whether through direct ownership and operation or a properly structured related-party arrangement, the right approach is a combined analysis. An engineering-based study should first determine whether the facility clears the 95% threshold and document the qualifying square footage, then separately identify any remaining components, such as land improvements outside the building footprint, that fall under standard cost segregation treatment rather than Section 168(n). Getting this sequencing right avoids double-counting and produces documentation that will hold up if the IRS examines the return.
The Section 1245 Recapture Clock
The 100% deduction under Section 168(n) comes with a meaningful string attached. If the property ceases to be used in a qualified production activity within 10 years of being placed in service, Section 1245 recapture applies. That means the accelerated deduction gets clawed back and taxed as ordinary income rather than the more favorable capital gains treatment that would otherwise apply to a sale of real property.
This is a materially longer and more punitive recapture exposure than what applies to typical cost segregation components. Investors who plan to hold a qualifying facility for a shorter period, sell it, convert it to a different use, or lease it to a tenant running a different kind of operation need to model the recapture exposure before claiming the deduction, not after. A large first-year write-off that gets recaptured at ordinary rates six years later because the business changed direction can turn out to be a much worse outcome than a smaller deduction claimed under conventional MACRS.
A Realistic Example
Consider an investor who owns a metal fabrication business and decides to build a new 40,000 square foot production facility, holding title in a separate LLC that leases the building back to the operating company under common ownership. Construction begins in March 2026 and the building is placed in service in January 2027, both dates falling inside the QPP windows. An engineering study determines that 97% of the building's square footage is dedicated to the fabrication floor, tooling areas, and material staging, with the remaining 3% used for a small front office. Because the facility clears the 95% de minimis threshold, and because the related-party structure satisfies the original use requirement, the entire building, structural shell included, can be treated as QPP.
On a $4 million construction cost, that is a dramatically different first-year outcome than a conventional cost segregation study would produce. A standard study on the same building might identify $900,000 to $1.2 million in bonus-eligible components. Under Section 168(n), the full $4 million becomes eligible for the 100% special depreciation allowance, assuming the taxpayer group continues operating the qualifying activity and the 10-year recapture window is factored into the long-term hold strategy.
Now compare that to an unrelated investor who simply buys an existing warehouse and leases it to a manufacturing tenant with no common ownership. That investor gets none of this. The building follows standard MACRS, and a conventional cost segregation study identifying land improvements and personal property remains the correct and only available strategy.
What Rental Property Investors Should Actually Do
If you are a passive investor who owns or is considering industrial, warehouse, or flex space leased to an unrelated manufacturing tenant, Section 168(n) does not change your tax strategy. A conventional engineering-based cost segregation study, combined with permanent 100% bonus depreciation under Section 168(k) on qualifying components, remains the right tool, and it is still a powerful one.
If you also own or are connected to an operating manufacturing business, and you are structuring real estate ownership around that business, QPP is worth a serious conversation with your CPA and tax attorney before you finalize the entity structure, the lease terms, and the construction timeline. The original use requirement, the related-party rules, the 95% threshold, and the 10-year recapture window all need to be addressed at the planning stage, not discovered after the building is already placed in service.
The Bottom Line
Section 168(n) is a real and powerful provision, but it was built for manufacturers who own or effectively control the real estate they operate from, not for arm's length landlords. Notice 2026-16 confirms that the original use rule blocks the deduction whenever a tenant, rather than the taxpayer, is the one running the qualifying production activity. Understanding this distinction now will save you from building a tax plan around a strategy that will not survive an IRS examination.
