Built-to-Suit (BTS) Industrial Leases — What a Property Lawyer in Pune Wants You to Check Before You Sign

What Is a BTS Arrangement, and Why Companies Choose It

A Built-to-Suit — usually shortened to BTS — is an arrangement where a developer constructs a facility to an occupier's specifications on land the developer owns or controls, and then leases the completed facility back to that occupier on a long-term basis. The occupier gets a purpose-built factory, warehouse, or distribution centre without buying land, applying for NA conversion, or managing a construction project. The developer gets a long-term, pre-committed tenant before a single brick is laid.

For manufacturers, auto-component suppliers, and logistics operators expanding in Maharashtra, BTS has become one of the most common ways to acquire operating space — often faster than land acquisition, and without tying up capital that could otherwise go into machinery, inventory, or working capital. But the structure that makes BTS attractive — someone else builds, you occupy — is also what makes it legally different from either buying land or leasing an existing shed. The agreement has to do double duty: it is partly a construction contract and partly a lease, and if either half is drafted loosely, the gap shows up exactly when it is most expensive to fix — during construction, at handover, or at renewal.

Property lawyers in Pune have seen this pattern repeat across the city's industrial belt: a BTS deal negotiated primarily on rent and location, with the construction specification, timeline, and exit terms left thin — because those clauses feel procedural at the term-sheet stage. They stop feeling procedural the moment the building is six weeks late, or delivered with a column grid that does not match the occupier's production line layout.

The appeal of BTS is real and the model works well for both sides when it is documented properly. The risk is not in the concept — it is in how often the legal documentation is treated as a formality to be finalized after the commercial terms and construction have already begun, rather than as the instrument that actually determines what "built to suit" means in practice, clause by clause.

The Two-Agreement Structure Every BTS Deal Needs

A properly structured BTS transaction is documented through two connected but distinct instruments, plus a technical annexure that does more legal work than either.

Treating these as a single, undifferentiated "BTS agreement" is where most drafting problems begin. The construction phase and the occupancy phase carry fundamentally different risks, different remedies, and often different parties involved in oversight — a project manager and architect during construction, a facilities or legal team during occupancy. Documents that reflect this separation clearly are easier to enforce, because each phase's obligations can be assessed against its own, phase-appropriate standard rather than a single blended set of terms that fits neither phase particularly well.

1. Development Agreement (or Agreement to Lease-cum-Development)

This governs the construction phase — what will be built, to what specification, on what timeline, at whose cost for variations, and what happens if either side wants to walk away before completion. It typically includes the approved building plan, a construction schedule with milestones, provisions for the occupier's site inspection rights during construction, and — critically — a mechanism for handling change requests without derailing the entire project.

2. Lease Deed or Leave and License Agreement

This takes effect from the date of possession and governs the occupancy phase — rent, security deposit, lock-in, renewal, escalation, maintenance, and termination. Many BTS deals sign this document upfront, with a "deemed commencement" clause tied to a completion certificate or occupancy certificate, so both parties know exactly what triggers the shift from construction risk to occupancy risk.

3. The Specification Annexure

This is the document most parties underinvest in, and it is usually the single biggest source of BTS disputes. The specification annexure describes the building in operational detail — floor loading capacity, column spacing, dock door count and height, power load, fire-fighting systems, effluent treatment provisions, and finishing standards. When this annexure is vague ("as per industry standard specifications") rather than precise ("floor loading of 5 tonnes per square metre, column-free bay of 24m x 30m"), the occupier has no enforceable basis to reject a building that technically meets the developer's own interpretation of "standard" but does not meet the occupier's actual operational needs.

BTS vs. Buying Land vs. Leasing an Existing Shed

BTS sits between two other common paths to industrial space, and the right choice depends on capital position, timeline, and how customized the facility needs to be.

Leasing an existing (non-BTS) shed sits at the opposite end from buying land — fastest to occupy, lowest customization, and typically used where the operational fit does not need to be precise. BTS is chosen specifically when a business needs purpose-built specifications but does not want to carry construction and land-holding risk directly.

The Clauses That Decide Whether a BTS Deal Works

Beyond the specification annexure, a small number of clauses account for most of the value — and most of the risk — in a BTS agreement.

Stamp Duty & Registration of the Lease Deed

A BTS lease deed, like any lease of immovable property in Maharashtra, attracts stamp duty calculated with reference to the average annual rent, the security deposit, and the lease term — and a lease for a term exceeding 11 months and 29 days is compulsorily registrable under the Registration Act, 1908. Because BTS leases typically run 9 to 15 years, registration is not optional, and skipping it — a shortcut occasionally proposed to save time or duty — leaves the occupier without an enforceable, admissible lease in the event of a dispute.

Getting the stamp duty calculation right at signing matters more on a BTS deal than on a standard lease, because the numbers involved are larger and the consequences of an under-stamped document are correspondingly more serious — an insufficiently stamped lease deed cannot be relied upon in court as evidence until the deficient duty and penalty are paid, which can seriously weaken a party's position exactly when the document is needed most, such as during a dispute over possession or rent default. A property lawyer in Pune structuring a BTS deal will typically work through the duty calculation, and the registration logistics for a large-format industrial or warehousing lease, well before the signing date — not as an afterthought once commercial terms are agreed.

Registration also has a practical benefit beyond enforceability: a registered lease creates a clear public record of the occupier's interest in the property, which becomes relevant if the occupier ever needs to demonstrate its right to possession to a bank, an equipment financier, or a regulatory authority during the lease term.

Maintenance & CAM Charge Structuring

Where a BTS facility sits within a larger developed park — sharing internal roads, common security, effluent treatment, or a common gate — Common Area Maintenance (CAM) charges are usually billed separately from base rent. Disputes over CAM are common precisely because these charges are often left loosely defined at signing: what is included, how costs are allocated across tenants, whether there is a cap on annual escalation, and what audit rights the occupier has over the developer's CAM expense statements. A BTS lease that leaves CAM as "actuals, as determined by the developer" gives the occupier very little recourse if charges rise sharply in later years of a long lease term.

Risks Unique to Built-to-Suit

Some risks in a BTS transaction are shared with any commercial lease. Others are specific to the fact that construction and occupancy are bound together in a single deal.

Underlying Land Title Risk Inherited by the Occupier

An occupier does not own the land in a BTS deal, but that does not insulate them from title risk on it. If the developer's title to the underlying land is defective — an unresolved tenancy claim, a pending acquisition notification, or an unconverted NA status — the occupier's leasehold right is only as strong as the developer's underlying ownership. A BTS occupier should insist on the same category of land due diligence a direct purchaser would conduct, even though they are only leasing.

Approval Risk at Handover

A building can be structurally complete and still not be legally ready for occupation. Occupancy certificate, fire NOC, MPCB Consent to Establish and Consent to Operate, and — where relevant — factory registration are all required before an industrial or warehousing facility can lawfully begin operations. A BTS agreement should make handover and rent commencement conditional on these approvals being in place, not merely on physical construction being finished.

Developer's Risk on Occupier Default or Early Exit

The risk runs both ways. A developer who has built a highly customized facility to one occupier's specification carries real exposure if that occupier exits early or defaults — the building may not be easily re-let to a different tenant without retrofitting. This is precisely why lock-in periods, exit penalties, and security deposit quantum in BTS deals tend to be higher than in a standard lease, and why developers negotiate hard on these terms.

Insurance & Force Majeure Allocation

A BTS agreement should clearly divide insurance responsibility across the two phases it governs. During construction, the developer typically carries contractor's all-risk insurance covering the building under construction. Once the lease commences, responsibility usually shifts — the developer insures the structure itself, while the occupier insures its own equipment, inventory, and business interruption risk. Where this division is left unstated, a fire, flood, or structural event can trigger a dispute over who was supposed to be covered for what, at precisely the moment neither side can afford ambiguity. A force majeure clause calibrated to Indian conditions — covering not just the standard list of natural disasters but also extended regulatory delays in obtaining approvals — gives both sides a clear, pre-agreed path if construction or operations are disrupted by events outside anyone's control.

Financing & Security Structuring

Because a BTS deal typically represents a significant capital commitment for the developer and a long-term operating commitment for the occupier, the security package attached to the agreement deserves as much attention as the rent figure itself.

Developers commonly require a security deposit equivalent to several months' rent, sometimes supplemented by a bank guarantee that can be invoked without extended dispute in the event of default — particularly where the occupier is a newly incorporated Indian subsidiary of a foreign parent with a limited independent credit history. In such cases, a corporate guarantee from the foreign parent company is frequently negotiated alongside the lease, giving the developer recourse beyond the Indian entity's own balance sheet. On the occupier's side, negotiating a reducing security deposit structure — where the deposit steps down after a defined period of clean payment history — is a common way to free up capital once the relationship has proven stable.

Why BTS Is Booming in Pune's Industrial Corridor

The Chakan-Talegaon-Ranjangaon belt, along with the warehousing clusters closer to the Pune-Mumbai and Pune-Solapur corridors, has seen a sharp rise in BTS activity — driven by auto and EV component manufacturers scaling capacity, and by 3PL and e-commerce logistics operators expanding distribution footprint without tying up capital in land.

This growth is also why BTS legal risk is concentrated here in specific, recognizable patterns. Land underlying BTS developments in this corridor often traces back through the same family-held agricultural parcels discussed in industrial land acquisition generally — meaning the title risks a direct land buyer would investigate are just as relevant to a BTS occupier evaluating a developer's site, even though the occupier's name never appears on the sale deed. A property lawyer in Pune working BTS deals in this corridor routinely reviews the developer's underlying land title alongside the lease terms themselves, precisely because the two cannot be assessed independently of each other.

Who Needs This — and When

BTS structures serve a wide range of occupiers and developers, each with a distinct set of priorities in the negotiation.

Across all of these profiles, the point of maximum leverage is before the development agreement is signed — once construction has started, the occupier's negotiating position on specification and timeline weakens considerably, because reversing course mid-build is expensive for everyone. Involving a property lawyer in Pune at the term-sheet stage, rather than after the development agreement has already been drafted by the developer's side, is what preserves that leverage. The same is true for developers: a lease and development agreement negotiated carefully at the outset, with default and exit scenarios addressed in writing, protects the developer's construction investment far more effectively than a strongly worded default clause invoked after a dispute has already begun.

Ten Questions to Ask Before You Sign

Before signing a BTS development agreement or lease deed, run this quick diagnostic. If you cannot confidently answer most of these, the agreement needs another round of review before signature.

• Does the specification annexure use measurable, numeric standards — floor loading, clear height, dock count — rather than general phrases like "industry standard"?
• Has the developer's underlying land title been independently verified, including NA status and any acquisition notifications?
• Is rent commencement tied to occupancy certificate and joint inspection, rather than a fixed calendar date?
• Does the agreement include liquidated damages for construction delay, calibrated to your actual commercial exposure?
• Is there a defined change order process for specification revisions during construction, with clear cost allocation?
• Are lock-in period, early exit rights, and exit penalties clearly quantified rather than left to future negotiation?
• Are security deposit terms — quantum, interest, refund timeline, and deduction conditions — fully specified?
• If a parent company guarantee is being offered or required, has it been reviewed for enforceability under Indian law?
• Does the agreement clearly separate the construction-phase and occupancy-phase obligations, so responsibility does not become ambiguous at handover?
• Has a lawyer reviewed both the development agreement and the lease deed together, rather than each in isolation?
