What Is a Build-to-Suit Lease?
A build-to-suit lease is a contractual arrangement in which a developer (or landlord) agrees to design and construct a commercial building according to a tenant’s specific requirements, and the tenant agrees to lease the completed facility for a predetermined term and rental rate. The developer funds the construction — either through equity, construction loans, or a combination — and recovers the investment through the lease payments over the term.
BTS leases are most common in industrial and logistics (distribution centers, manufacturing plants), single-tenant retail (quick-service restaurants, drugstores, auto parts stores), corporate office (headquarters, regional offices), and healthcare (medical office buildings, ambulatory surgery centers). The defining characteristic is that the building would not exist without the specific tenant’s commitment — it is purpose-built for their operations.
How BTS Differs from Traditional Leasing
In a traditional lease, the landlord offers existing space and the tenant negotiates rent based on market conditions. In a BTS arrangement, there is no existing building — the rent is fundamentally driven by the cost of development rather than comparable market rents. This creates an entirely different negotiation dynamic, where construction budgets, timelines, and design specifications become central to the lease terms rather than peripheral considerations.
| Factor | Traditional Lease | Build-to-Suit Lease |
|---|---|---|
| Rent Basis | Market comparables | Development cost × cap rate |
| Lease Term | 3–10 years typical | 15–20 years typical |
| Tenant Improvement | TI allowance from landlord | Built into total project cost |
| Design Control | Limited to interior fit-out | Full building shell + interior |
| Construction Risk | Minimal (existing building) | High — cost overruns, delays |
| Occupancy Timeline | Weeks to months | 12–24 months from execution |
| Credit Requirements | Standard financial review | Stringent — investment-grade preferred |
| Exit Flexibility | Moderate (shorter terms) | Low — long-term commitment required |
Developer vs. Tenant Responsibilities
The allocation of responsibilities between developer and tenant is the foundation of every BTS transaction. Misalignment here leads to disputes, cost overruns, and project delays.
Developer’s Typical Obligations
- Land acquisition and entitlements — securing the site, zoning approvals, environmental clearances, and building permits
- Construction management — hiring and supervising the general contractor, subcontractors, and design professionals
- Financing — arranging construction loans and permanent financing, bearing interest carry during development
- Base building delivery — completing the structural shell, core mechanical systems, parking, and site improvements
- Warranty coordination — ensuring contractor warranties transfer to the tenant or landlord entity as appropriate
Tenant’s Typical Obligations
- Design specifications — providing detailed requirements for layout, ceiling heights, floor loads, HVAC capacity, electrical service, and specialized equipment
- Timely approvals — reviewing and approving design documents, shop drawings, and material selections within agreed timelines
- Tenant-specific equipment — procuring and installing racking, fixtures, technology infrastructure, and specialized production equipment
- Operating expenses — paying NNN charges (property taxes, insurance, maintenance) throughout the lease term
- Change order costs — funding any tenant-requested changes that exceed the approved scope and budget
Cost Allocation: Shell vs. Tenant Improvements
Understanding how costs are allocated between the base building (shell) and tenant improvements (TI) is critical because it determines not only the total rent but also the accounting treatment, tax depreciation schedules, and each party’s ownership rights upon lease termination.
| Cost Category | Industrial / Warehouse | Office | Retail |
|---|---|---|---|
| Land | 10–20% of total cost | 15–35% of total cost | 20–40% of total cost |
| Hard Costs (Shell) | 45–55% | 35–45% | 30–40% |
| Tenant Improvements | 5–15% | 15–25% | 15–25% |
| Soft Costs | 8–12% | 10–15% | 10–15% |
| Developer Fee / Profit | 3–5% | 4–6% | 4–6% |
| Financing / Carry Costs | 3–5% | 4–6% | 3–5% |
| Typical Total PSF | $85–$150 | $250–$500 | $200–$400 |
Guaranteed Maximum Price (GMP) Provisions
The GMP is the single most important cost control mechanism for tenants in a BTS transaction. Under a GMP arrangement, the developer commits to delivering the completed building for a maximum total cost. If actual costs exceed the GMP, the developer absorbs the overrun. If costs come in under budget, the savings are typically shared — a common split is 50/50 or 60/40 in favor of the tenant.
Key negotiation point: Tenants should insist that the GMP includes a detailed line-item budget with contingency clearly identified (typically 5–10% of hard costs). Without line-item transparency, the developer can bury excess contingency across categories, effectively inflating the GMP while maintaining the appearance of a competitive price.
BTS Rent Calculation from Development Cost
The fundamental formula for BTS rent is straightforward, but the inputs require careful scrutiny. Rent is a function of total development cost and the agreed-upon capitalization rate (cap rate), which reflects the developer’s required return and the tenant’s credit quality.
The cap rate is the lever that swings the most value. A 50-basis-point difference on a $15 million project translates to $75,000 per year — or $1.5 million over a 20-year term. Credit tenants (investment-grade rated by S&P or Moody’s) typically command cap rates of 6.5–7.5%, while non-credit tenants see cap rates of 8.0–9.5% or higher, reflecting the developer’s increased risk of default.
NPV Comparison: BTS Lease vs. Self-Development
Tenants frequently evaluate whether to pursue a BTS lease or develop the facility themselves using corporate capital. The NPV comparison illuminates the true cost of each path.
Construction Timelines and Delay Penalties
Construction delays are among the highest-risk elements of a BTS transaction. Every month of delay costs the tenant in temporary facility expenses, lost revenue, or extended holdover at their current location — while the developer faces increased interest carry and potential breach claims.
Typical BTS Construction Timelines
- Pre-development (entitlements, design, permitting): 3–6 months
- Industrial / warehouse (tilt-up or steel frame): 8–14 months
- Office (multi-story): 14–24 months
- Retail (single-story pad): 6–10 months
- Total from LOI to occupancy: 12–30 months depending on property type
Delay Penalty Structures
Most BTS leases include a liquidated damages provision that compensates the tenant for developer-caused delays beyond the scheduled delivery date. Common structures include:
- Rent abatement — one day of free rent for each day of delay, applied after rent commencement
- Per diem penalties — a fixed daily payment (often $500–$5,000/day) from the developer to the tenant
- Escalating penalties — lower rate for first 30 days of delay, escalating for each subsequent 30-day period
- Termination right — if delay exceeds a threshold (typically 120–180 days), the tenant may terminate the lease entirely
Red Flag #1: No force majeure carve-out for material shortages. In 2025–2026 construction markets, material lead times for structural steel, switchgear, and specialized HVAC equipment can extend 20–40 weeks. If the lease does not excuse delays caused by material unavailability beyond the developer’s control, the developer bears enormous risk — or passes hidden contingency costs into the GMP.
Design Approval Rights and Change Order Procedures
The interplay between the tenant’s right to approve design decisions and the developer’s obligation to maintain budget and schedule is one of the most tension-filled aspects of BTS transactions.
Design Approval Stages
- Schematic design (SD) — overall building layout, massing, site plan. Tenant approval required before advancing.
- Design development (DD) — detailed floor plans, structural systems, MEP specifications. Tenant has 10–15 business days to review and approve.
- Construction documents (CD) — permit-ready drawings. Tenant reviews for conformance with DD-approved design.
- Shop drawings and submittals — manufacturer-specific details for materials and equipment. Tenant approval on key items only.
Change Order Protocol
Change orders are modifications to the approved scope after construction has commenced. Every BTS lease should include a detailed change order protocol covering:
- Cost impact — the developer provides a written estimate of the additional cost (or credit) within 5–10 business days
- Schedule impact — the developer identifies any delay to the delivery date
- Approval threshold — changes below a dollar threshold (e.g., $25,000) may proceed with manager-level approval; larger changes require executive sign-off
- Cost allocation — tenant-requested changes are funded by the tenant (either added to the project cost and capitalized into rent, or paid directly)
- Documentation — all change orders must be in writing and signed by both parties before work proceeds
Red Flag #2: Verbal change order authorization. If the lease permits the developer to proceed with changes based on verbal tenant approval, the tenant loses cost control. Insist on written authorization with cost and schedule impact disclosed before any change order work begins.

The rent commencement date (RCD) is the point at which the tenant’s obligation to pay rent begins. In a BTS lease, this is not a fixed calendar date — it is tied to the completion of construction. The most common triggers include:
- Substantial completion — the building is complete per the lease specifications, a certificate of occupancy (or temporary CO) has been issued, and only minor punch-list items remain
- Tenant occupancy — rent commences when the tenant takes physical possession and begins operating, even if punch-list items are outstanding
- Outside date — a hard deadline (e.g., 18 months from construction start) after which rent commences regardless of completion status, protecting the developer from indefinite delay
- Hybrid trigger — the earlier of substantial completion or a specified outside date, with rent abatement credits if delivery is late due to developer fault
Red Flag #3: Outside date set too early without tenant protections. If the outside date does not exclude tenant-caused delays and force majeure events, the tenant could be paying rent on a building that isn’t yet usable. Negotiate for the outside date to toll during any period of tenant-caused delay, force majeure, or government-imposed construction moratorium.
Purchase Options and Right of First Refusal
Many tenants negotiate the right to purchase the BTS facility during or at the end of the lease term. This preserves flexibility to eventually own the asset they’ve been paying for. Common purchase option structures include:
- Fair market value (FMV) option — exercisable at specified intervals (e.g., years 7, 10, 15), with FMV determined by independent appraisal or broker opinion
- Fixed-price option — a predetermined purchase price, often set at original development cost plus a premium (e.g., 5–10%)
- Right of first refusal (ROFR) — if the developer receives a bona fide third-party purchase offer, the tenant has the right to match it
- Right of first offer (ROFO) — the developer must first offer the property to the tenant before marketing it to third parties
Accounting alert: A bargain purchase option (priced significantly below expected FMV at exercise) will almost certainly cause the lease to be classified as a finance lease under ASC 842, which requires the tenant to record the building as an asset on its balance sheet. This may be undesirable for tenants seeking off-balance-sheet treatment.
ASC 842 Implications for Build-to-Suit Leases
The accounting treatment of BTS leases under ASC 842 is among the most technically complex areas of lease accounting. The central question is: Who is the accounting owner of the asset during construction?
Control Indicators
Under ASC 842, a tenant may be deemed the accounting owner of a BTS asset during construction if they exhibit control over the construction project. Key indicators include:
- The tenant directs the structural design and specifications beyond standard tenant improvements
- The tenant has the right to approve the general contractor and major subcontractors
- The tenant bears construction period risk (e.g., cost overruns, change orders at tenant’s expense)
- The tenant funds a significant portion of construction costs during the build phase
- The tenant has a purchase option at a below-market price
If the tenant is deemed the accounting owner, they must recognize the asset and a corresponding liability on their balance sheet during construction — even before they occupy the building. After construction is complete, they must evaluate whether the arrangement can be “de-recognized” and reclassified as an operating lease, or whether it remains a finance lease.
Red Flag #4: Tenant-directed construction without accounting analysis. Many tenants negotiate extensive design approval rights and construction oversight without considering the ASC 842 implications. If the lease gives the tenant control over the construction process, they may inadvertently trigger on-balance-sheet treatment for the entire building — adding tens of millions to reported liabilities and reducing key financial ratios.
Credit Tenant Requirements
BTS developers and their lenders evaluate tenant creditworthiness with far greater scrutiny than in a typical lease transaction. The developer is committing millions in construction capital based primarily on the tenant’s promise to pay rent for 15–20 years. Key credit requirements include:
- Investment-grade rating — BBB– or better (S&P) / Baa3 or better (Moody’s) is the gold standard for BTS financing
- Financial statement review — three to five years of audited financials, with focus on revenue stability, debt coverage ratios, and liquidity
- Corporate guarantee — if the tenant is a subsidiary or SPE, the parent company typically must guarantee the lease obligations
- Security deposit or letter of credit — non-investment-grade tenants may be required to post 6–12 months of rent as security
- Net worth covenants — ongoing requirements to maintain minimum net worth or revenue thresholds throughout the lease term
Market Rent Resets and Escalation Structures
BTS leases with 15–20 year initial terms must address how rent adjusts over time. Unlike a conventional lease where rent resets to market at renewal, BTS leases use structured escalation provisions:
- Fixed annual increases — 1.5–2.5% per year, providing predictable growth for the developer and budgetable costs for the tenant
- CPI-based escalations — rent adjusts annually based on Consumer Price Index changes, often with a floor (1%) and cap (3%)
- Step-ups at intervals — rent increases at years 5, 10, and 15 by a predetermined percentage (e.g., 10% per step)
- Fair market value resets — rent resets to FMV at specified intervals, protecting both parties from sustained divergence between contract rent and market
Red Flag #5: Uncapped CPI escalation without a ceiling. In inflationary environments, uncapped CPI escalations can produce rent increases far exceeding what the tenant budgeted. A tenant that signed a BTS lease in 2022 with uncapped CPI escalation saw their rent increase 8.7% in a single year. Always negotiate a cap (2.5–3.5% maximum annual increase) even in CPI-based structures.
The 12-Point BTS Lease Negotiation Checklist
Whether you represent the tenant or the developer, these twelve provisions should be carefully negotiated in every build-to-suit transaction:
- Guaranteed Maximum Price (GMP) — confirm a firm cap on total development cost with a detailed line-item budget, identified contingency, and shared savings mechanism
- Cap rate and rent calculation — agree on the capitalization rate, define exactly which costs are included in the rent basis, and confirm the formula in a lease exhibit
- Construction schedule and milestones — establish a detailed timeline with interim milestones, identify the critical path, and define consequences for missed deadlines
- Delay penalties and force majeure — negotiate liquidated damages for developer-caused delays, define excusable delays (weather, material shortages, government actions), and set an outside termination date
- Design approval rights — specify the tenant’s approval rights at each design stage (SD, DD, CD) with defined review periods and deemed-approval provisions
- Change order protocol — require written authorization, cost/schedule impact disclosure, and clear allocation of costs between tenant-requested and developer-initiated changes
- Rent commencement trigger — define substantial completion criteria, CO requirements, punch-list completion timelines, and the relationship between the outside date and tenant-caused delays
- Purchase option structure — if applicable, negotiate the pricing mechanism (FMV, fixed, formula), exercise windows, and accounting implications of the option
- Rent escalation structure — agree on fixed, CPI, or step-up escalations with appropriate floors and caps to protect both parties over the long term
- ASC 842 / accounting provisions — structure the lease to achieve the desired accounting treatment (operating vs. finance) by carefully allocating construction risk and control
- Renewal options and end-of-term provisions — define renewal term lengths, rent reset mechanisms, notice periods, and the tenant’s obligations for surrender condition at expiration
- Assignment and subletting rights — negotiate flexibility for corporate restructuring, permitted transfers to affiliates, and subletting rights if the tenant’s space needs change over a 20-year horizon
Red Flags in Build-to-Suit Lease Agreements
Beyond the red flags identified above, watch for these additional warning signs that can expose tenants to significant financial risk:
Red Flag #6: Cost-plus pricing with no GMP. A pure cost-plus arrangement means the tenant bears 100% of construction cost risk. The developer has no financial incentive to control costs, and every change order, delay, or material price increase flows directly into higher rent. If the developer insists on cost-plus, negotiate a “not-to-exceed” cap with a meaningful contingency buffer.
Red Flag #7 (combined): Developer retains unilateral value engineering rights. If the developer can substitute materials or systems to reduce costs without tenant consent, the tenant may receive a lower-quality building while paying rent based on the original budget. Require that all value engineering savings be shared and that material substitutions require written tenant approval.
