A build to suit lease is a long-term commercial real estate arrangement in which a developer buys a site and constructs a building to a single tenant’s exact specifications, and the tenant commits to occupy that building under a lease that typically runs 10 to 30 years. These deals exist because some businesses need features the standing market cannot deliver: unusual ceiling heights, reinforced floors for heavy machinery, specialized ventilation, or loading configurations that only make sense for one operation. The tenant gets a purpose-built facility without tying up capital in ownership. The developer gets a creditworthy tenant locked in long enough to recoup construction costs and earn a return.
That trade is the whole logic of the structure. Everything else — how rent is set, who takes which risks, what the contract has to say — follows from it.
How the Rent Is Actually Calculated
Rent in a build to suit deal is not pulled from comparable market rates. It is built from the total development cost: land acquisition, construction, architectural and engineering fees, permits, and financing charges. The developer applies a return-on-cost rate, sometimes called a rent factor or capitalization rate, to that total. If all-in development cost lands at $10 million and the agreed return rate is 8 percent, annual base rent is $800,000. The specific rate reflects current interest rates, the tenant’s credit profile, the length of the lease, and local conditions.
This math has a direct consequence: every design decision the tenant makes shows up in rent. A second loading dock, an upgraded HVAC system, a reinforced slab — each one raises development cost, which raises rent for the full term. The longer the lease, the lower the annual rent factor tends to run, because the developer has more years to recover the investment. Tenants who understand this negotiate harder during design, because changes made after construction starts cost even more.
The Main Deal Structures
Developer-Led
The traditional structure puts the developer in charge of everything: site acquisition, construction financing, hiring contractors, managing the build. The developer keeps ownership of land and improvements. The tenant signs a long-term lease, usually on a triple net basis, meaning the tenant pays base rent plus property taxes, building insurance, and maintenance. Triple net terms shield the developer’s rental income from unpredictable ownership costs, which is a large part of why lenders will finance these projects at all.
Under this model, construction risk sits with the developer. If materials cost more than planned, if the project runs late, if site conditions produce surprises, those problems belong to the developer unless the lease says otherwise. The tenant’s job is to pay the agreed rent once the building is ready. That clean division of risk is the reason most build to suit tenants prefer the traditional structure.
Reverse Build to Suit
A reverse build to suit flips the construction responsibilities. The tenant manages design, hires the contractors, and runs the build. The landlord funds the work, either by reimbursing the tenant through construction draws at milestones or by paying the general contractor directly. When construction finishes, the tenant occupies the building under a pre-negotiated lease.
Tenants with in-house construction expertise or unusually specialized requirements sometimes prefer this because it gives them direct control over quality and scheduling. The tradeoff is that construction risk shifts to the tenant. Budget overruns, contractor disputes, permitting delays — those all land on the tenant. And cost increases the tenant causes through design changes or mismanagement still result in higher rent, because the landlord adjusts lease economics to reflect actual development costs.
Sale-Leaseback Variation
Some build to suit transactions are structured as sale-leasebacks. The tenant builds, or arranges to build, the facility on land it already owns, then sells the completed property to an investor and simultaneously signs a long-term lease to stay in it. This unlocks the capital tied up in real estate while keeping the business in a purpose-built facility. It shows up most often in corporate real estate strategies where companies want to redeploy capital into core operations rather than carry property on their balance sheets.
What a Tenant Needs Before Negotiating
Financial Documentation
A developer putting up a multimillion-dollar building for one tenant needs strong evidence that tenant can pay for the full term. Plan on providing at least three years of audited financial statements or tax returns. The developer’s lender will review these closely, because the tenant’s creditworthiness is the foundation of the entire financing package. A tenant with weaker financials can still get a deal done, but should expect a larger security deposit, a personal guaranty, or both, and higher financing costs that flow through to rent.
Technical Specifications
Detailed design documents should exist before the lease is signed. Square footage, ceiling heights, floor load capacity, electrical and plumbing requirements, HVAC specifications, and any specialized features like clean rooms, cold storage, or reinforced loading areas all need to be defined upfront. Vague specifications create change orders later, and change orders create disputes and cost increases. The sharper the specifications at signing, the smoother the project.
Zoning and Environmental Due Diligence
Both parties should confirm that the proposed use complies with local zoning before any serious money is spent on design and permitting. Discovering a zoning problem after signing is an expensive mistake.
Environmental diligence is equally important. A Phase I Environmental Site Assessment reviews whether the site has a history of contamination from previous industrial or commercial use. Under federal law, conducting “all appropriate inquiries” into a property’s environmental history before acquisition is a prerequisite for asserting the innocent landowner defense against cleanup liability under CERCLA.1Office of the Law Revision Counsel. 42 USC 9601 – Definitions Skipping this step can leave a property owner on the hook for millions in remediation costs if contamination surfaces during construction.
Insurance
A builder’s risk insurance policy is essential during construction. It covers damage to the partially completed structure and stored materials from risks like fire, theft, vandalism, and severe weather. The property owner or general contractor usually buys the policy, but the lease should spell out who does. Every party with a financial stake — tenant, developer, general contractor, subcontractors, construction lender — should be named as an insured. Gaps here can wipe out months of progress with no recourse.
The Lease Clauses That Decide Whether This Works
Rent Commencement and Substantial Completion
The rent commencement date is the single most important date in the lease. Most build to suit leases tie it not to a calendar date but to “substantial completion” of construction. Substantial completion means the building is functional enough for the tenant to use it for its intended purpose, even if minor punch list items remain. That protects the tenant from paying rent on an unusable building and ensures the developer begins collecting income once the facility is genuinely ready.
If the developer misses the target date, the lease should carry consequences. Liquidated damages structured as daily or weekly rent credits give the developer real incentive to stay on schedule. The tenant should also negotiate an outside completion date: a hard deadline past which the tenant can walk away from the deal if the building still is not finished. Without that backstop, a tenant can be trapped waiting for a building that may never arrive.
Cost Overruns and Guaranteed Maximum Price
Who pays when a project goes over budget? In a developer-led deal, the developer generally absorbs overruns because rent was calculated from a fixed development budget. But “generally” is not “always.” Some leases shift the risk of unforeseen site conditions, environmental remediation, or extreme material cost increases to the tenant, and this is where lease language earns its keep.
A guaranteed maximum price (GMP) contract between the developer and the general contractor adds a layer of protection. Under a GMP, the contractor agrees to complete the project for no more than a stated amount; if actual costs exceed the cap, the contractor eats the difference. This puts overrun risk on the party best positioned to control it. Tenants should push for a GMP contract and make sure the lease is explicit that overruns beyond the GMP are the developer’s problem.
Force Majeure
Force majeure clauses excuse construction delays caused by events genuinely outside either party’s control. In federal construction contracts, the standard list of excusable events includes natural disasters, fires, floods, epidemics, quarantine restrictions, labor strikes, and freight embargoes.2Acquisition.GOV. FAR 52.249-14 Excusable Delays Private build to suit leases typically track a similar framework, though the specific list is negotiable.
The common mistake is accepting vague language like “economic hardship” or “supply chain disruptions.” Phrases that broad can excuse almost any delay. Strong force majeure clauses define specific triggering events, sometimes with objective thresholds such as material cost increases exceeding a stated percentage above the original budget. The clause should also require prompt written notice from the claiming party and reasonable efforts to mitigate.
Construction Warranties
Construction warranties protect the tenant against defects that surface after move-in. The industry standard warranty period is one year from final acceptance or occupancy, covering defects in materials and workmanship.3Acquisition.GOV. FAR 52.246-21 Warranty of Construction During that year, the developer or contractor must repair deficiencies at their own expense, including restoring any work damaged while making the repair.
Twelve months is not enough for everything. Structural defects, foundation problems, and waterproofing issues often take longer to show themselves. Latent defect provisions extend the developer’s responsibility for hidden problems beyond the standard warranty period. The tenant should negotiate latent defect coverage of at least five to ten years for major structural elements, with a clear obligation to remedy any defect that was not reasonably discoverable during the initial warranty window.
Change Orders
Design changes after signing are inevitable. Equipment needs evolve, regulations shift, or a layout that looked right on paper does not work in practice. Change order protocols set a formal process: written approval from both parties, a cost estimate from the contractor, and explicit adjustments to both budget and timeline.
Tenants should watch how change orders affect rent. In a developer-led deal, additional cost from tenant-requested changes typically raises the development budget, which raises rent for the entire term. A $50,000 change order looks manageable on its own, but at an 8 percent return rate over 20 years it adds $4,000 per year to rent. Stack a few of those together and the impact compounds quickly.
SNDA Agreements
This is one of the most overlooked protections in build to suit leasing, and skipping it can be catastrophic. When a developer finances construction with a loan, the lender takes a security interest in the property. If the developer later defaults, the lender can foreclose. Without a Subordination, Non-Disturbance, and Attornment agreement in place, the new owner can refuse to recognize the tenant’s lease and evict the tenant from a facility that was custom-built for its business.
An SNDA has three pieces. Subordination establishes the priority of the lender’s mortgage relative to the lease. Non-disturbance, the critical piece for the tenant, guarantees that if the lender forecloses, the tenant can stay in the building for the remainder of the lease on the same terms. Attornment requires the tenant to recognize the new owner — whether the lender or a buyer at foreclosure — as the landlord. Tenants should insist on an SNDA before signing and should check that the non-disturbance protections are unconditional.
Expansion Rights
A business that expects to grow should negotiate expansion rights into the original lease rather than trying to add them later. These provisions give the tenant the ability to expand beyond the initial space into additional areas controlled by the landlord. The lease should specify which type applies:
- Right of first offer: the landlord must offer available adjacent space to the tenant before marketing it to third parties.
- Right of first refusal: the tenant can match the terms offered by a third party seeking the same space.
- Predetermined expansion option: the tenant has the right to expand into a defined area on a specific date or upon a triggering event.
On larger sites, the clause may also address the tenant’s right to construct additional improvements on unused portions of the property. The lease should define who pays for the expansion, how rent adjusts, and whether the expansion extends the term.
How Construction and Delivery Unfold
Once the lease is signed, the developer submits final plans to the local building department for permits. Commercial permit fees commonly run between 0.5 and 1.2 percent of total project value, not counting plan review, trade permits, and impact fees. Heavily regulated jurisdictions tend toward the upper end. Timelines vary just as widely: straightforward projects in cooperative jurisdictions may clear in weeks, while complex builds in strict jurisdictions can take months.
During construction, the tenant should retain the right to monitor progress through site inspections and regular reporting. Progress payment applications document how much work has been completed and how much has been billed. That paper trail gives the tenant visibility into schedule and budget, and if the lease includes liquidated damages for late delivery, it creates the record needed to enforce them.
Construction concludes when the local authority issues a Certificate of Occupancy, confirming the building meets all applicable safety and building codes. The parties then conduct a final walkthrough and create a punch list of minor items. Formal delivery of possession — when the tenant takes control and the rent clock starts — happens at substantial completion rather than final completion of every punch list item. The lease should spell out exactly how many days the developer has to finish punch list work after delivery.
What Happens at the End of the Term
Renewal Rights
A facility built to one tenant’s specifications is hard for a developer to re-lease to anyone else, which gives the tenant real leverage on renewal terms. Most build to suit leases include at least one or two renewal options, often in five-year increments. Renewal rent is usually reset to fair market value or a predetermined escalation rather than the original build-to-suit rate, because by then the developer has already recovered construction costs.
Purchase Options and Right of First Refusal
Many tenants negotiate the right to buy the property at or before lease end. A fixed-price option sets the price at signing or ties it to a formula. A fair-market-value option gives the tenant the right to buy at appraised value. A right of first refusal is lighter: if the landlord decides to sell to a third party, the tenant gets a chance to match the third party’s offer. Purchase options can affect how the lease is classified for accounting purposes, so tenants should bring in their accountants early.
Holdover Provisions
If the tenant stays past the expiration date without a signed renewal, holdover provisions take over. These impose a rent premium meant to discourage month-to-month occupancy. Rates of 150 percent of the final month’s base rent in the short term, escalating to 200 or even 300 percent for extended holdover, are common in commercial leases. For a build to suit tenant occupying a highly specialized facility with no realistic alternative, holdover terms matter more than usual. Push for a grace period of 60 to 90 days at a more moderate premium, around 125 percent, to allow room for renewal negotiations without punitive rent.
Tax and Accounting Considerations
Depreciation
The party that owns the building for tax purposes claims depreciation on the improvements. In a traditional developer-led build to suit, that is the developer. Nonresidential real property is depreciated over 39 years using the straight-line method under the Modified Accelerated Cost Recovery System.4Internal Revenue Service. Publication 946, How To Depreciate Property Qualified improvement property, which covers interior improvements to a nonresidential building placed in service after the building’s original in-service date, qualifies for a shorter 15-year recovery period.5Office of the Law Revision Counsel. 26 USC 168 – Accelerated Cost Recovery System Improvements to elevators, escalators, or the building’s internal structural framework do not qualify for the 15-year period.
This matters for tenants who fund their own interior buildout. If the tenant pays for qualifying interior improvements, the tenant, not the landlord, claims the depreciation deduction over 15 years. Tenants making significant capital investments in a build to suit space should work with a tax advisor to classify each component properly and capture the deductions available.
Lease Accounting Under ASC 842
The current lease accounting standard, ASC 842, changed how build to suit transactions show up on financial statements. The prior standard treated a tenant bearing substantially all construction risk as the accounting owner of the building during construction, even if the developer held legal title. ASC 842 replaced that risk-based test with a control-based test.
Under current rules, the tenant is treated as the accounting owner of the asset during construction only if the tenant controls the underlying asset. Control exists if, among other situations, the tenant has the right to acquire the partially completed building at any point during construction, the tenant legally owns both the land and the improvements, or the tenant controls the land and the lease term covers substantially all of the property’s economic life. Heavy involvement in design or acting as general contractor, by itself, does not establish control.
If the tenant is deemed the accounting owner, it has to record construction costs on its balance sheet as an asset with a corresponding financing obligation, then apply sale-and-leaseback accounting when the lease begins. If the tenant does not control the asset during construction, it simply records the lease under standard ASC 842 lease accounting at commencement. The difference can move reported debt levels and financial ratios materially, which is why the accounting team belongs in the room before the lease is structured, not after.
