A client finds the right office space and asks: “What’s the monthly rent?” Whatever number you give them will be incomplete — not because you lied, but because commercial rent in India is never just the per-square-foot figure on the listing sheet.
CAM charges, security deposits, lock-in clauses, rent escalation, fit-out periods, and GST at 18% all sit between the quoted rent and what a tenant actually pays every month. Most occupiers don’t know this. Many brokers don’t explain it proactively. The ones who do — clearly, before the deal closes — are the ones clients call back for every future transaction.
This guide breaks down every clause in a commercial lease that matters, what each one means for your client’s bottom line, and how to negotiate each one effectively.

Why Commercial Leases Are Structurally Different From Residential Ones
Residential leases in India are governed primarily by state Rent Control Acts, which heavily protect the tenant. Commercial leases operate almost entirely on contract law — they are freedom-of-contract agreements, which means whatever the two parties agree to in writing becomes the law between them.
This matters enormously for brokers. There is no standard commercial lease template in India. Every landlord — especially in multi-tenanted Grade A buildings — uses their own heavily negotiated agreement, usually drafted in favour of the landlord. The burden on the broker is to help the occupier understand exactly what they are signing up for before the lease is executed.
The key structural differences: commercial leases typically have longer tenures (3–9 years), mandatory lock-in periods where early exit triggers significant penalties, separate charges for building maintenance and services (CAM), and no statutory cap on security deposits. Under the Transfer of Property Act, 1882, leases exceeding one year must be registered as a deed, which incurs stamp duty and registration charges — an additional cost most tenants only discover during documentation.
Commercial properties leased to registered businesses (where the landlord is GST-registered) attract 18% GST on the monthly rent. This GST is recoverable as Input Tax Credit (ITC) by the tenant if they are also a GST-registered entity — but for small businesses, unregistered entities, or professional services firms not claiming ITC, it is a real additional cost that must be factored into the true monthly outgo.
The practical implication for brokers: never lead a commercial lease conversation with the headline rent. Lead with the all-in monthly cost — rent + CAM + parking + GST — so the client makes their decision based on what they will actually pay.
The Five Clauses That Cost Businesses the Most
In our observation of commercial lease disputes in India, the same five clauses consistently create problems for occupiers — not because they are hidden, but because they are rarely explained in plain language before signing.
1. Lock-In Period: This is the minimum guaranteed tenancy period. If a tenant exits during the lock-in, they typically forfeit the security deposit and may owe rent for the remaining lock-in months. Standard lock-in periods run 12–36 months for mid-sized office users; large enterprise deals often carry 36–60 month lock-ins in exchange for fit-out contributions from the landlord. Brokers should negotiate the lock-in relative to the client’s business certainty — a startup should never accept a 36-month lock-in without an exit mechanism. One negotiable tool is a break clause: the right to terminate at a defined milestone (typically month 18 or 24) with 3–6 months’ notice, sometimes with a termination penalty.
2. Rent Escalation: Almost every Indian commercial lease contains an escalation clause — typically a 5% to 15% increase every 3 years. This is often written as a flat percentage in the agreement, but the exact trigger date, compounding structure, and whether it applies to CAM charges as well as base rent all vary. Read this clause carefully: a 15% escalation every 3 years on a ₹5 lakh per month lease adds ₹75,000 per month at first escalation, and ₹86,250 at the second.
3. CAM Charges (Common Area Maintenance): CAM covers the shared cost of running the building: lobbies, lifts, parking, housekeeping, security, power backup for common areas, and facilities management. In Grade A office buildings, CAM is typically billed at a fixed rate per sq ft per month — but the key negotiation point is whether there is a cap on annual CAM escalation. Without a cap, CAM charges can escalate faster than base rent. Always get itemised CAM: what is included, who audits it, and what the escalation mechanism is.
4. Fit-Out Period (Rent-Free Period): When a tenant takes a bare-shell space, they need time to complete fit-out before the space is usable. Standard practice is for landlords to grant 1–3 months of rent-free period for fit-out. This is negotiable based on the size of the space, the length of the lease, and the landlord’s occupancy situation. Larger deals may include a fit-out contribution from the landlord — called a tenant improvement allowance — which is more common in enterprise office deals above 50,000 sq ft. Always negotiate this clause; never assume it is standard.
5. Security Deposit: Commercial security deposits in India are not legally capped. Market practice ranges from 6 to 12 months’ rent, with 6 months being standard for smaller offices and 10–12 months common in premium Grade A buildings. The security deposit earns no interest (unless negotiated), which means a ₹10 lakh/month office with a 10-month deposit ties up ₹1 crore of a business’s working capital for the entire lease tenure. Brokers who highlight this capital cost — and negotiate it down — deliver measurable financial value to their clients.
GST on Commercial Rent: What Every Broker Must Be Able to Explain
The Goods and Services Tax applies to commercial property leasing at 18% (CGST 9% + SGST 9%) when the landlord is a registered GST entity. This applies to offices, retail spaces, warehouses, and industrial units.
For GST-registered businesses renting commercial property, the GST paid on rent qualifies as Input Tax Credit (ITC) — meaning they can offset it against their GST output liability. In practical terms, for a company that regularly collects GST from its own customers, the GST on rent is recoverable and does not increase the real cost.
Where this becomes a genuine cost is for: (a) businesses not registered under GST, (b) exempt-supply businesses (hospitals, educational institutions, certain financial services), and (c) small tenants under the GST threshold. For these categories, 18% GST on rent is a real, non-recoverable expense.
Brokers must ask the client upfront: “Are you GST-registered and claiming ITC?” If yes, calculate the net rent cost after ITC recovery. If no, add 18% to every monthly rent figure you quote them. Not asking this question — and presenting a rent-exclusive-of-GST number to a client who cannot recover it — is one of the most common causes of post-agreement friction in commercial leasing.
Residential property rented to an individual for personal use remains exempt from GST. But residential property rented by a GST-registered business (even for use as staff accommodation) is taxable at 18% under the current framework — a point that confuses many first-time commercial tenants who are renting an apartment as a satellite office.
Stamp Duty and Registration on Commercial Lease Agreements
Under the Transfer of Property Act, 1882, any lease for a term exceeding one year must be registered as a lease deed. This registration attracts stamp duty, which varies by state and the duration of the lease.
Stamp duty on commercial leases in India typically ranges from 0.25% to 2% of the total lease value (annual rent × lease period), depending on the state. In Maharashtra, stamp duty on a commercial lease deed is calculated on the average annual rent plus any premium paid. In Delhi, the rate varies based on the lease period. Registration charges are typically 1% of the property value/lease consideration, subject to state-specific caps.
Two points that frequently catch tenants off-guard. First, stamp duty on commercial leases is calculated on the entire lease value — not just the first year’s rent — which means a 5-year commercial lease at ₹3 lakh/month carries a stamp duty basis of ₹1.8 crore (60 months × ₹3 lakh). At a 1% stamp duty rate, that is ₹1.8 lakh in stamp duty alone. Second, where a tenant has paid a large security deposit or advance, some states include a portion of this in the stamp duty calculation as a “premium.”
Brokers must always factor stamp duty and registration into the total transaction cost — particularly for leases exceeding 3 years, where these costs can be material. Advising the client after the lease is signed is too late.
How to Negotiate a Commercial Lease: A Practical Playbook
Most tenants approach lease negotiation as a rent negotiation. The smarter approach — and what distinguishes a good broker from a transactional one — is to negotiate the total occupancy cost.
The following are the most negotiable elements of a commercial lease in India, in rough order of value to the tenant:
| Lease Element | Landlord’s Opening Position | What Tenants Can Realistically Achieve |
| Base Rent | Listed market rate | 5–10% reduction for longer commitment |
| Fit-Out/Rent-Free Period | 1 month standard | 2–3 months for bare shell, more for large spaces |
| Security Deposit | 10–12 months | 6–8 months, especially with good tenant covenant |
| CAM Escalation Cap | Uncapped or linked to actuals | 5% annual cap with audit rights |
| Break Clause | Not offered | Exit at month 18–24 with 3–6 months’ notice |
| Parking Allocation | Charged separately per slot | 1 slot per 1,000 sq ft included in rent |
The broker’s leverage in negotiation comes from two things: the client’s covenant strength (a funded startup or MNC pays a lower deposit) and market context (in a high-vacancy building, almost everything is negotiable). Always know the building’s occupancy before your first negotiation meeting — it tells you exactly how much room the landlord has to move.
Sirf Broker POV: The Headline Rent Is a Marketing Number, Not a Business Decision
Here is what we see repeatedly in the Indian commercial leasing market: brokers present the per-square-foot rent, the client falls in love with the space, and the lease is signed before anyone has done the math on the total occupancy cost. Three months later, the client is surprised by their monthly outgo — and that surprise becomes distrust, not gratitude.
The commercial lease in India is not a single number. It is a stack of commitments: base rent, CAM charges (which can add 20–25% on top in a Grade A building), GST on the total, parking charges billed separately, and a security deposit that locks up 6–12 months of rent as interest-free capital. When you add it up, the all-in monthly cost is routinely 40–60% above the headline rent. This is not deception — it is structure. But the broker’s job is to make that structure transparent before the client commits, not after.
Our position: the brokers who will dominate commercial leasing in India’s next growth phase are not the ones who close fastest. They are the ones who show up to the first meeting with a proper total-cost-of-occupancy breakdown — rent, CAM, GST, parking, deposit opportunity cost, stamp duty — and help the client make a genuinely informed decision. That is not extra work. That is what differentiates a real estate advisor from a listing agent. If you are not giving your occupier clients a full cost picture before they sign, you are not doing your job — and you are leaving the door open for the broker who will.
Conclusion
Commercial leases in India reward informed tenants and informed brokers. The five clauses explored here — lock-in, escalation, CAM, fit-out, and security deposit — are the primary levers of a deal’s total value. Understanding GST and stamp duty implications rounds out the picture.

Frequently Asked Questions
What is a CAM charge in a commercial lease in India?
CAM stands for Common Area Maintenance. It is a charge paid by tenants to cover the cost of maintaining shared building spaces — lobbies, lifts, corridors, security, housekeeping, and power backup for common areas. In Grade A office buildings, CAM is charged at a fixed per-sq-ft rate per month, separate from the base rent. It typically adds 15–30% on top of the base rent in premium buildings.
Is GST applicable on commercial rent in India?
Yes. Commercial property leasing is subject to 18% GST when the landlord is a registered GST entity. For GST-registered businesses, the GST paid on rent can be claimed as Input Tax Credit (ITC) and offset against their output tax liability. For unregistered businesses or those in exempt-supply sectors, the GST is a real, non-recoverable cost that must be added to the true monthly rent.
What is a lock-in period in a commercial lease and can it be broken?
A lock-in period is the minimum guaranteed tenure during which the tenant cannot exit the lease without financial penalty. Standard lock-ins range from 12 to 36 months for office spaces. If a tenant exits during the lock-in period, they typically forfeit the security deposit and may owe remaining lock-in rent. A break clause — the right to exit at a defined date with advance notice — can be negotiated into the agreement and is the recommended way to protect a tenant against business uncertainty.
How much security deposit is standard for a commercial office in India?
Market practice for commercial security deposits in India ranges from 6 to 12 months’ rent. Smaller offices and independent buildings typically accept 6 months. Premium Grade A buildings in markets like Mumbai BKC, Gurugram, or Bengaluru Whitefield often demand 10–12 months. Unlike residential deposits, commercial security deposits earn no interest unless specifically negotiated. A good broker will always push to reduce the deposit amount or secure interest-bearing terms.
Does stamp duty apply to commercial lease agreements in India?
Yes. Under the Transfer of Property Act, 1882, commercial leases exceeding one year must be registered as a lease deed, which attracts stamp duty. The rate varies by state and is typically calculated on the total lease value (annual rent multiplied by the number of years). Stamp duty on commercial leases generally ranges from 0.25% to 2% depending on the state and lease duration, with registration charges of approximately 1% of the lease consideration. These costs must be factored into the overall transaction budget before the deal is finalised.
How is rent escalation typically structured in Indian commercial leases?
Most Indian commercial lease agreements include a fixed-percentage rent escalation clause — typically 5% to 15% every 3 years. Some leases index escalation to CPI or WPI, though flat-percentage escalation is more common in practice. Brokers should flag three things in the escalation clause: the trigger date (when does the first escalation hit), whether it compounds or is calculated on base rent, and whether CAM charges escalate on the same schedule. Uncapped CAM escalation with a below-market rent can still result in an expensive lease overall.
