Build-to-suit accounting under ASC 842 turns on one question: does the tenant control the asset while it’s being built? Answer that, and everything else follows — balance sheet treatment during construction, lease classification at commencement, and whether a sale-leaseback at the end even qualifies as a sale. Get it wrong and you may be restating financials, because the control test can pull a tenant onto its own balance sheet for a building it never intended to own.
What a Build-to-Suit Arrangement Looks Like
A build-to-suit (BTS) deal is a real estate transaction in which a landlord constructs or significantly customizes a property for a single tenant. The tenant specifies the design, layout, and features; the landlord develops to those specifications. That level of customization is what separates BTS from a lease of existing space, and it’s also what drives most of the accounting complexity. A distribution center built around one company’s automated sorting system, for example, often has little practical use for anyone else. That lack of alternative use will come back into the analysis more than once.
Every BTS arrangement splits into two accounting periods. The construction period runs from the start of development until the asset is substantially complete. The lease period begins when the tenant takes possession. Each period has its own rules, and the construction period is where the harder decisions live.
The Construction-Period Control Test
ASC 842 uses a control-based framework, borrowed from ASC 606, to decide who owns the asset for accounting purposes during construction. If the tenant controls the asset, the arrangement is treated as an asset purchase with a financing liability rather than a lease. If the tenant does not, no lease accounting happens until the tenant takes possession and the lease commences.
ASC 842-40-55-5 lists five indicators of tenant control. Meeting any single one makes the tenant the accounting owner during construction:
- The tenant has the right to obtain the partially built asset mid-construction, such as through a call option paid to the landlord.
- The landlord has a legally enforceable right to payment for work completed to date, and the asset has no alternative use to the landlord. Both conditions must be present together.
- The tenant legally owns both the land and the improvements under construction. For non-real-estate assets such as ships or aircraft, ownership of the asset itself is enough.
- The tenant controls the land where improvements will be built and has not leased it to the landlord or a third party for substantially all of the improvements’ economic life before construction begins.
- The tenant leases the land for a term covering substantially all of the improvements’ economic life and has not subleased it to the landlord or a third party for a similar duration before construction starts.
The first three indicators trace directly to the ASC 606 control concept. Even when none of the five explicit indicators applies, a tenant can still be deemed to control the asset under the broader ASC 606 framework, though in practice most BTS assessments turn on one of the five listed items.
One point about the no-alternative-use test: you look at the characteristics of the finished asset, not the asset in its partially completed state. A half-built shell might look adaptable, but if the final design specifications lock in features that only work for one company, the no-alternative-use analysis follows those final specifications.1FASB.

When the Tenant Is the Accounting Owner During Construction
If the control test makes the tenant the accounting owner, the arrangement is not a lease during construction. The tenant capitalizes construction costs as a construction-in-progress asset under ASC 360 (property, plant, and equipment). As the landlord funds construction, the tenant records a corresponding financing liability for the amounts advanced.
The landlord treats its construction funding as a loan receivable from the tenant rather than as an investment in a building it owns. Neither party runs lease accounting until construction is complete and a separate assessment determines what has happened next.
When construction ends, one of two paths opens. If the tenant retains the asset, it stays on the tenant’s books and the financing liability amortizes like a conventional loan. If the tenant transfers the completed asset to the landlord and leases it back, the transaction moves into sale-leaseback territory, which has its own tests.
Lease Classification When Construction Ends and the Tenant Is Not the Owner
If the tenant did not control the asset during construction, the standard ASC 842 lease model applies at commencement. The tenant classifies the lease as either finance or operating based on five criteria. Meeting any one triggers finance lease treatment:
- The lease transfers ownership of the asset to the tenant by the end of the lease term.
- The tenant has a purchase option it is reasonably certain to exercise.
- The lease term covers the major part of the asset’s remaining economic life.
- The present value of lease payments equals or exceeds substantially all of the asset’s fair value.
- The asset is so specialized that it has no alternative use to the landlord at the end of the lease term.
That fifth criterion is the one BTS arrangements often trip. A highly customized building with no practical use for another tenant will frequently satisfy it even when the other four don’t apply, which is why BTS leases so often end up as finance leases.
Finance Lease
The tenant recognizes a right-of-use (ROU) asset and a lease liability at commencement. The income statement carries two separate expenses: straight-line amortization of the ROU asset and interest expense on the lease liability. The interest component is front-loaded and declines over time, so total expense is higher in the early years and tapers off.
Operating Lease
An operating lease also puts an ROU asset and lease liability on the balance sheet, but the income statement carries a single straight-line lease expense over the lease term. No separate breakout of interest and amortization. For companies watching earnings patterns, this difference between finance and operating classification matters.
Discount Rate: Implicit Rate or IBR
The discount rate used to measure the lease liability directly affects how large the liability appears. ASC 842 requires the tenant to use the rate implicit in the lease when it can be readily determined. In practice, the implicit rate is rarely available, because computing it requires the landlord’s expected residual value of the asset, which most landlords do not share.
When the implicit rate cannot be determined, the tenant uses its incremental borrowing rate: the interest rate it would pay to borrow a similar amount, on a collateralized basis, over a similar term, in the current economic environment. For a specialized BTS asset, the IBR calculation requires thought about what kind of collateral is appropriate and how the asset’s specialization affects borrowing terms.
The IBR should reflect the tenant’s actual credit profile rather than a theoretical best case. Weaker credit means a higher rate, which produces a smaller lease liability but more interest expense over the life of the lease. A tenant that cannot obtain third-party financing due to its financial condition should start with the lowest-grade market debt rate and adjust for collateral.
Landlord Classification
The landlord runs the same five criteria and arrives at one of three classifications: sales-type, direct financing, or operating. Because BTS assets are often highly specialized, the no-alternative-use criterion frequently pushes landlords into sales-type treatment.
Sales-Type Lease
A sales-type lease is the landlord equivalent of a sale. The landlord derecognizes the building, records a net investment in the lease (essentially a receivable), and recognizes any profit or loss at commencement. Interest income accrues on the net investment over the lease term.
Direct Financing Lease
If none of the five classification criteria are met, the landlord tests for direct financing. The lease qualifies as direct financing when the present value of lease payments plus any third-party residual value guarantee equals or exceeds substantially all of the asset’s fair value, and collection is probable. Under direct financing, the landlord defers any selling profit and recognizes it gradually over the lease term through interest income.
Operating Lease
A lease that fails both the sales-type and direct financing tests is an operating lease. The building stays on the landlord’s balance sheet and is depreciated over its useful life, and rental income is recognized on a straight-line basis. For BTS assets this outcome is uncommon, because the specialization usually satisfies at least one of the classification criteria.
Collectibility
Even when a lease qualifies for sales-type or direct financing classification, the landlord cannot use that accounting if collection of lease payments is not probable. In that case the landlord keeps the asset on its books, does not derecognize it, and treats any cash received as a deposit liability until either collection becomes probable or the lease terminates with the amounts received nonrefundable. Skipping this check is a common lessor error.
Sale-Leaseback When the Tenant Owned During Construction
A sale-leaseback BTS transaction happens when the tenant is the accounting owner during construction, finishes the building, sells it to the landlord, and leases it back. Two hurdles have to be cleared for this to receive sale-leaseback accounting: the transfer must qualify as a sale, and the leaseback cannot be classified in a way that suggests the tenant never really gave up control.
Does the Transfer Qualify as a Sale?
The sale test comes from ASC 606. Control has genuinely passed to the landlord when the landlord has a present obligation to pay, the tenant has a present right to that payment, and the landlord can direct the use of and obtain the remaining benefits from the asset.2PwC Viewpoint. Sale and Leaseback – Determining Whether a Sale Has Occurred
Repurchase options are where these deals often fail. A fixed-price repurchase option generally prevents sale treatment because the exercise price won’t necessarily reflect the asset’s fair value at the time. A repurchase option at then-prevailing fair value can work, but only if substantially similar assets are readily available in the marketplace. For real estate, that second condition is nearly impossible to satisfy because every location is unique. Most BTS sale-leasebacks involving real estate with a repurchase option therefore fail the sale test.
The Leaseback Classification Gate
Even when the transfer qualifies as a sale under ASC 606, sale-leaseback accounting is blocked if the leaseback is classified as a finance lease by the tenant or a sales-type lease by the landlord. Either signals that the tenant effectively retained control, which contradicts the premise of a sale. Only an operating leaseback allows sale-leaseback treatment to proceed.
Failed Sale-Leaseback
When the transaction fails, neither party changes its balance sheet to reflect a sale. The tenant keeps the building on its books and continues depreciating it. The cash received from the landlord becomes a financial liability, and lease payments split between interest expense and principal repayment. The landlord doesn’t record the building; it records the cash paid as a loan receivable, with incoming lease payments split between interest income and principal recovery.
One safeguard applies. The interest rate on the tenant’s financial liability must be adjusted so that interest never exceeds the principal payments over the shorter of the lease term or the financing term, and so that the asset’s carrying amount never exceeds the liability’s carrying amount by the time control ultimately transfers to the landlord.
Separating Lease and Non-Lease Components
A BTS contract rarely covers only the right to use a building. Maintenance, property management, janitorial services, and common area upkeep frequently sit inside the same agreement. Under ASC 842, non-lease components must be identified and separated from the lease component because they follow different accounting rules.
Tenants have a practical expedient: they can elect, by asset class, to skip the separation and treat the entire contract as a single lease component. This simplifies the work but inflates the ROU asset and lease liability because non-lease payments get folded in. Whether that trade is worth it depends on the size of the services and the effort separation would take.
Landlords have a version of the same expedient with tighter conditions. The landlord can combine components only when the timing and pattern of transfer are the same for both and the lease component standing alone would be classified as an operating lease. If the non-lease component is the predominant element of the combined package, the landlord accounts for the whole arrangement under the revenue standard rather than the lease standard.
Variable Payments
BTS leases often carry payments that change over time, and how they’re treated depends on what drives the variability.
Payments tied to an index or rate, such as an annual escalation based on CPI, are included in the lease liability at commencement using the index or rate as of that date. The liability isn’t adjusted for future expected changes in the index. It’s remeasured only when the actual payments change because of an index update.
Payments tied to performance or usage, such as percentage rent based on the tenant’s sales, are excluded from the lease liability entirely and recognized as expense in the period the obligation is incurred. Common area maintenance charges that vary based on actual costs generally fall into this excluded category.
Two BTS leases with identical total expected payments can produce very different lease liabilities depending on structure. A lease with high base rent and low variable components shows a larger liability than one with low base rent and substantial performance-based payments. Structuring decisions during negotiation flow directly into the numbers.
Tenant Improvement Allowances
Many BTS deals include a tenant improvement allowance where the landlord funds tenant-directed customization beyond the base construction. Under ASC 842, a TIA is a lease incentive that reduces the tenant’s ROU asset.
If the TIA hasn’t been received at commencement, the reduction also flows through to the lease liability as a decrease in future minimum lease payments. If the TIA is paid upfront, it reduces the ROU asset but creates a separate leasehold improvement asset for the amount received, which the tenant then amortizes over the shorter of its useful life or the remaining lease term.
Modifications and When to Reassess
Construction projects change. Scope adjustments, design modifications, and cost overruns are routine, and the accounting effect depends on when the change occurs and what it does to the arrangement.
The BTS control guidance in ASC 842-40 applies specifically to construction that occurs before lease commencement. If significant improvements are made to an already-leased asset during the lease term, the BTS guidance generally doesn’t apply; the changes are evaluated under the standard lease modification rules.
There’s one exception worth watching. If construction-period changes are so extensive that the tenant effectively loses the right to use the underlying asset during the modification work, and the result is essentially a new lease commencement date, the BTS control assessment may need to be performed again. The test is whether the tenant maintained continuous use of the asset throughout the modification period. If it did, the changes are treated as lessee-owned improvements. If it didn’t, the full control assessment may be triggered again.
Separately, if a contract allows the tenant to expand leased space by constructing a physically distinct adjacent structure, that new construction is a separate unit of account. The BTS control analysis applies independently to the new space even though the original lease is already in effect.
Common Mistakes
A handful of errors come up over and over, and they’re expensive to fix later.
The most frequent one is treating the construction-period control test as a formality. Companies assume that because the landlord is managing construction and will end up owning the building, the tenant can’t be the accounting owner. The control indicators, though, look at legal rights, not who is directing the work. A tenant that owns the land, holds a call option on the partially built asset, or has negotiated an arrangement where the landlord has an enforceable right to payment on a highly specialized asset can end up as the accounting owner even when the landlord runs every aspect of development.
Another mistake is failing to reassess when deal terms change during construction. A renegotiated purchase option, a land transfer, or a shift in which party bears completion risk can flip the outcome. This is not a one-time exercise done at signing and filed away.
On the lessor side, overlooking collectibility causes real problems. A landlord that classifies a BTS lease as sales-type and books a day-one profit, then finds that collection wasn’t probable, has to reverse the treatment and hold the asset on its books with payments recorded as deposits.
Finally, the no-alternative-use criterion gets underestimated on both ends. A building constructed to one tenant’s exact specifications will often satisfy it during the construction-period control test and again at lease classification. The specialization that makes BTS attractive from a business perspective is the same feature that produces most of the accounting complexity.
