Common Mistakes in Commercial Property Leasing Deals | Sirf Broker

A commercial lease is not a document you sign and forget. It is a multi-year financial and legal commitment — one that defines how much a business pays, what it can do with the space, how easily it can exit, and what happens when something goes wrong.

And yet, commercial leasing deals in India are routinely completed with mistakes that should never have happened — mistakes in due diligence, in lease drafting, in cost calculation, in document verification, and in the assumptions both parties bring to the table without checking.

The consequences are not minor. A tenant who signs a lease with a poorly drafted escalation clause may pay lakhs more than anticipated over a five-year term. A landlord who leases to a tenant without verifying their creditworthiness may face months of rent default before legal remedies kick in. A broker who completes a transaction without checking the land use classification may find their client shut down by the local authority, with the broker’s reputation attached to the outcome.

Most of these mistakes are not made by people who are careless or uninformed in general. They are made by people who are in a hurry, who assume that because one party seems professional, the documents must be in order, or who have done residential transactions well for years and assume commercial works the same way.

It does not.

This article covers every significant and recurring mistake in commercial property leasing deals — from the due diligence stage to the post-signing stage — with specific guidance on how to prevent each one.

1. Skipping Land Use Verification — The Most Expensive Assumption

Of all the mistakes in commercial leasing, this one has the most severe consequences — and is made most often by brokers who come from a residential background.

Every commercial property has a designated land use in the local development plan or master plan. A property can only be legally occupied for its designated purpose. A warehouse on agricultural land, an office in a residential zone, a manufacturing unit in a commercial zone — all of these are violations with real regulatory consequences.

What happens when land use is not verified:

• The local authority issues a sealing or closure order — sometimes with very little notice
• Utility connections — electricity and water — are connected at the wrong tariff category and can be disconnected or reclassified.
• The tenant’s business operations are interrupted or shut down entirely
• The lease deed is unenforceable for an illegal purpose — the tenant has limited legal protection
• The broker’s reputation is permanently damaged with that client

Why does it keep happening?

Brokers assume the landlord knows their own land use classification. Tenants assume that because the building looks operational and has been occupied before, the land use must be correct. Neither assumption is safe.

A previous tenant may have occupied the space in violation, without ever facing enforcement. A building constructed on agricultural land may look identical to one on properly classified commercial land. The classification is in the government records — not visible from the outside.

The fix:

Check the local development authority’s portal for the specific survey number or khasra number of the property — not a general locality map. Confirm the designated use matches the proposed occupancy before arranging a single site visit. This takes 30 minutes. The consequence of skipping it can take years to resolve.

2. Comparing Options on Base Rent Alone — Missing the True Cost

This is the mistake that most frequently causes budget overruns in commercial leasing — and it is made by tenants and brokers alike.

In commercial real estate, the base rent is never the total occupancy cost. Once CAM charges, GST, parking, electricity, and security deposit opportunity costs are added, the actual cost can be 60 to 100 per cent higher than the headline rent figure.

A real illustration of the gap:

A tenant is choosing between two offices:

Option A — ₹65 per sq ft base rent Option B — ₹85 per sq ft base rent

Option A looks meaningfully cheaper. But:

Once parking is added on a per-sq-ft basis, the options are within 5 per cent of each other — not 24 per cent apart as the base rent comparison suggested.

What the broker must always do:

Present a total occupancy cost comparison — across every cost component — before the client makes a shortlisting decision. A client who makes a decision based on base rent and later discovers the full cost has not been well served.

3. Not Reading the Lock-In Clause Carefully — The Trap That Cannot Be Undone After Signing

The lock-in period is the clause that generates the most disputes in commercial leasing — and the one that is most often read without being properly understood.

A lock-in period is the duration during which neither party can terminate the lease. Standard commercial lock-ins run three to five years. This means a tenant who signs a five-year lease with a three-year lock-in cannot exit for the first three years without a penalty — regardless of what happens to the business.

The most common lock-in mistakes:

Lock-in that binds only the tenant: Many landlord-drafted lease deeds include a lock-in clause that binds the tenant but not the landlord, giving the landlord the right to terminate for reasons like sale of the property, personal use, or redevelopment, while the tenant has no exit. A lock-in that is not mutual is not truly a lock-in — it is a one-sided commitment.

No break clause: For growing companies, startups, or businesses in transformation, a break clause — the right to exit at a defined mid-lease point with sufficient notice — is essential. A tenant who signs a five-year lease with no break clause in a business that doubles in size within two years has no option but to stay in an undersized space or pay a break penalty.

Unclear penalty for early exit: The penalty for exiting during the lock-in must be explicitly stated — not left to “as mutually decided.” A vague penalty clause creates disputes. An explicit clause — “the tenant shall forfeit the security deposit and pay rent for the remaining lock-in period” — is enforceable and clear.

What brokers must do:

Explain the lock-in clause to both parties before the lease deed is drafted. Flag any asymmetry. Recommend that the break clause be discussed during the Letter of Intent stage — not after the lease deed is in circulation.

4. Ignoring the OC Status — A Non-Negotiable That Gets Negotiated Away

The Occupancy Certificate (OC) is the municipal authority’s confirmation that a commercial building has been constructed as per the approved plan and is fit for occupation. Without it, the building’s occupation is technically illegal.

Despite this, a significant number of commercial leases in India are signed for buildings without a valid OC — because the tenant is in a hurry, the rent is attractive, or the broker does not raise it.

What happens when a tenant occupies a building without an OC:

• Utility connections — electricity, water — cannot be formalised in the tenant’s name
• The Fire NOC may be provisional or absent — creating insurance complications
• If the local authority conducts an inspection, the building can be sealed or the occupants asked to vacate
• The tenant’s fit-out investment — ₹50 to ₹80 lakh in a typical commercial office — is at risk of being stranded in a property that cannot be legally occupied.

Why does it keep happening?

Landlords tell tenants the OC is “in process” or “expected shortly” — and tenants accept possession under this assurance. The OC then takes months or years to arrive — or never arrives because the building has construction deviations that the authority will not approve.

The fix:

Do not sign a commercial lease and do not accept possession without the OC in hand. If the tenant is willing to take the risk — because the location is genuinely irreplaceable — the risk must be explicitly acknowledged in writing, the lease must include a timeline for OC delivery with a rent abatement or exit clause if it is not delivered, and the tenant must have taken independent legal advice.

5. Accepting Vague CAM Charges — The Cost That Compounds Without a Ceiling

CAM charges — Common Area Maintenance — are the single most frequently disputed element in Indian commercial leases. And in most cases, the dispute was avoidable if the CAM clause had been properly drafted.

The most common CAM-related mistakes:

No cap on annual CAM increase: If the lease does not specify a maximum annual increase in CAM charges, the landlord can — and often does — increase them significantly year-on-year. A tenant who budgeted for ₹20 per sq ft CAM in year one may be paying ₹32 per sq ft by year three.

No written breakdown of what CAM includes: “CAM charges as applicable” is not a contractual definition. Without a written breakdown, the landlord can include ineligible costs — capital expenditure on building improvements, depreciation of building equipment, costs specific to other tenants — in the CAM calculation.

No audit rights: Without the right to audit the building’s actual operating expenses, the tenant has no way to verify that CAM charges are being calculated correctly. In a multi-tenant building, the allocation method — and whether it is being applied correctly — can only be verified through an audit.

No gross-up provision: In a building that is partially vacant, fixed CAM costs are shared among fewer tenants — meaning each occupied tenant bears a higher proportionate share. A gross-up provision — which calculates variable CAM costs as if the building is at least 85 to 90 per cent occupied — protects occupied tenants from this effect.

What brokers must do:

Before a commercial lease is signed, ensure the CAM clause includes:

• A written breakdown of what is and is not included
• A cap on annual increase — typically 5 to 8 per cent
• Audit rights for the tenant — annually or on request
• A gross-up provision if the building has a meaningful vacancy
• Exclusion of capital expenditure and ineligible costs from the CAM calculation

6. Not Verifying the Landlord’s Authority to Lease — For Corporate and Institutional Landlords

In commercial leasing, landlords are frequently companies, trusts, or partnerships — not individuals. And a lease signed by an unauthorised representative of a corporate landlord may not be legally binding on the company.

The most common authority verification failures:

No Board Resolution: A company can only authorise specific individuals to sign on its behalf through a Board Resolution. If the person who signs the lease has not been formally authorised by the board, the lease may be unenforceable against the company.

Outdated PoA: If the landlord’s representative is acting on a Power of Attorney — verify that the PoA is registered, current, not revoked, and specifically authorises the leasing of this property. A PoA that has expired or been revoked gives the agent no authority.

Joint ownership without all owners’ consent: If the property is jointly owned by multiple family members, business partners, or co-promoters, all owners must consent to the lease. A lease signed by one joint owner without the others’ knowledge or consent is challengeable.

What brokers must do:

For any corporate landlord — ask for the Certificate of Incorporation, the Board Resolution authorising the signatory, and confirmation that the company is the registered owner on the title documents. This is not an intrusive ask for a legitimate transaction. Resistance to providing these documents is a red flag worth taking seriously.

7. Leaving Out Key Commercial Terms at the LOI Stage — Renegotiating After Commitment

The Letter of Intent (LOI) or Term Sheet is the document that records the commercial terms agreed before the formal lease deed is drafted. It is not legally binding in most cases — but it sets the expectation framework for the lease negotiation.

The most common LOI mistake is leaving important commercial terms vague — with the intention of finalising them during lease deed drafting. By that point, both parties have invested time and money in the process — and walking away from a disagreement on terms that should have been resolved at the LOI stage is significantly more difficult.

Terms that must be explicitly agreed in the LOI — not deferred to the lease deed:

• Exact base rent — in ₹ per sq ft per month and as a total monthly amount
• CAM charges — current rate per sq ft and what is included
• Security deposit — number of months’ rent
• Lock-in period — duration and whether it is mutual
• Escalation — percentage, frequency, and whether it applies to base rent only or base rent plus CAM
• Fit-out period — duration and whether CAM applies during fit-out
• Renewal option — yes or no, and the terms
• Break clause — yes or no, and the terms
• Parking — number of slots, cost per slot, and type (dedicated vs shared)
• Stamp duty allocation — who bears the cost

A tenant who reaches the lease deed stage with these terms unresolved is negotiating from a weaker position — having already indicated intent to proceed.

8. Not Registering the Lease Deed — Leaving the Tenant Without Legal Protection

Under Section 17 of the Registration Act, 1908, a lease deed for a period exceeding 12 months must be registered. An unregistered commercial lease deed has limited legal enforceability — and cannot be produced as evidence in court in the event of a dispute.

Despite this, a significant number of commercial leases — particularly for smaller premises, older buildings, and transactions where the landlord resists the stamp duty cost — are not registered.

What an unregistered lease deed cannot do:

• Cannot be used as evidence in court if the landlord disputes the terms
• Does not bind the landlord’s successors — if the landlord sells the property, the new owner is not obligated to honour an unregistered lease.
• Cannot be used as the basis for sub-letting or assignment
• Does not protect the tenant against eviction if the landlord terminates the lease in violation of its terms

Why tenants accept unregistered leases:

Stamp duty on a long-term commercial lease — calculated on the total lease value — can be significant. Landlords sometimes resist registration because they do not want to pay stamp duty or disclose the rent to the tax authorities. Tenants sometimes accept this to avoid the cost or the delay.

The fix:

Insist on registration. For any commercial lease with a meaningful fit-out investment or a tenure of more than 12 months, an unregistered lease is an unacceptable risk. The stamp duty cost — shared between landlord and tenant as agreed in the LOI — is small compared to the legal exposure of operating without a registered document.

9. Not Accounting for Fit-Out Obligations at Lease End — A Surprise That Arrives Years Later

Most commercial tenants invest significantly in fitting out their leased space — false ceilings, raised floors, partitioned cabins, electrical panels, branding elements, server room infrastructure. At the time of signing, the reinstatement obligation — whether the tenant must restore the space to its original condition at lease end — receives very little attention.

During the time of vacation, it receives a great deal.

The most common reinstatement mistakes:

No clarity on what “original condition” means: If the lease says the tenant must return the space in its “original condition” without specifying what that means, the landlord and tenant will have different interpretations. Does it mean bare concrete? Does it mean the condition at the start of the lease? Is the fit-out the landlord provided at commencement included?

No provision for what happens to tenant fit-out: In most commercial leases, the tenant’s fit-out becomes the landlord’s property at the end of the lease — unless the landlord requires reinstatement. If the landlord wants reinstatement, the tenant bears the cost of demolition and restoration, which can run into lakhs for a fully fitted office. This cost must be budgeted for at the start of the lease — not discovered at the end.

No documentation of the pre-fit-out condition: If the pre-fit-out condition of the space is not documented — with photographs and a written schedule — there is no agreed baseline against which restoration is measured. Disputes are almost inevitable.

The fix:

At the LOI stage, agree explicitly whether reinstatement is required, what standard applies, and who bears the cost. Document the pre-fit-out condition with dated photographs and a written schedule, signed by both parties. This documentation is as important as the lease deed itself at the end of the tenancy.

10. Treating TDS and GST as Afterthoughts — Creating Compliance Problems

Commercial leasing transactions in India have specific tax obligations that are mandatory — not optional — and that create problems when they are not understood and planned for at the start of the transaction.

TDS on commercial rent:

Under Section 194-I of the Income Tax Act, a tenant is required to deduct TDS at 10% on commercial rent where the total annual rent exceeds ₹2,40,000. The tenant must:

• Deduct 10% from each rent payment
• Deposit it with the income tax department
• File the applicable TDS return
• Provide Form 16A to the landlord, so the landlord can claim the TDS as an advance tax credit

What happens when TDS is not deducted:

• The tenant is liable for the TDS amount plus interest — even if the landlord received full rent
• The tenant may face penalties under the Income Tax Act
• The landlord may receive an income tax notice for income that appears unverified on the return

GST on commercial rent:

If the landlord is GST-registered, the tenant must pay 18% GST on rent and CAM charges. The tenant can claim Input Tax Credit (ITC) on this — but only if they are GST-registered and use the property for taxable business activity.

A tenant who is not properly advised about GST may under-budget for the monthly occupancy cost by 18 per cent — a significant recurring shortfall.

What brokers must do:

At the LOI stage, confirm the landlord’s GST registration status. Include the TDS obligation in the standard transaction explanation given to every commercial tenant. Do not assume the client’s accountant will handle it — confirm it is understood before the lease is signed.

11. Neglecting the Dispute Resolution Clause — Finding Out How It Works When It Is Too Late

The dispute resolution clause is one of the most consistently neglected sections of a commercial lease, because at the time of signing, both parties believe the relationship will be smooth.

When a dispute arises — over CAM charges, over reinstatement obligations, over a rent abatement claim, over the landlord’s attempt to terminate — the dispute resolution clause determines how long the dispute takes and who has a structural advantage in the process.

The most common dispute resolution mistakes:

Arbitrator appointed solely by the landlord: Many landlord-drafted commercial leases include a clause giving the landlord the sole right to appoint the arbitrator in any dispute. This gives the landlord a structural advantage — a potentially sympathetic arbitrator — in any disagreement.

The tenant must negotiate for a neutral arbitrator appointment mechanism — either a mutually agreed appointment, or appointment by an independent institution such as the Indian Council of Arbitration.

Jurisdiction that does not match the property location: If the dispute resolution clause specifies jurisdiction in a city other than the property’s location — for the landlord’s administrative convenience — the tenant faces the cost and inconvenience of pursuing a dispute in an unfamiliar forum. Jurisdiction should match the property location.

No reference to RERA (for applicable properties): For mixed-use or under-construction commercial properties that are RERA-registered, the lease should not contain a clause that attempts to waive the tenant’s right to approach RERA. Such clauses are unenforceable — but their presence creates confusion.

What brokers must do:

Flag the dispute resolution clause for both parties before the lease deed is circulated. Recommend that the tenant’s lawyer specifically review the arbitrator appointment mechanism and the jurisdiction clause. This is a standard instruction — not an unusual request — in any professionally managed commercial transaction.

12. Closing the Deal Without a Lawyer — Saving a Fee That Costs Multiples Later

In a commercial leasing deal — particularly one involving a significant fit-out investment, a long lock-in period, or a complex building structure — the legal review fee is the cheapest insurance a tenant can buy.

Commercial lease deeds are drafted by the landlord’s lawyer, with the landlord’s interests as the primary consideration. Every clause that is favourable to the landlord and unfavourable to the tenant is intentionally drafted that way — not an oversight.

Without the tenant’s own lawyer reviewing the document, these clauses go unchallenged.

The clauses that a lawyer typically catches and renegotiates:

• One-sided lock-in binding only the tenant
• CAM charges with no cap and no audit rights
• Reinstatement obligation without a specified standard
• An arbitrator appointed solely by the landlord
• Force majeure clause that does not include rent abatement
• Sub-letting restriction with no provision for “consent not unreasonably withheld”
• Security deposit return timeline that is vague or absent

What brokers must do:

For any commercial lease above a threshold of ₹10 lakh annual rent, recommend legal review as a standard part of the transaction process — not as an optional extra. A tenant who declines is making an informed choice. A tenant who was never told about it has been underserved.

13. No Post-Signing Follow-Up — Leaving the Client Alone at the Most Operationally Critical Stage

The signing of the lease deed is not the end of the broker’s role. For the tenant, it is the beginning of the most operationally complex period — fit-out, possession, utility connection formalisation, move-in, and the first few months of occupancy.

Problems discovered in this period — an OC that is not forthcoming, a CAM charge that is higher than stated, a parking slot that is not as promised, a power supply that is inadequate for the tenant’s load — are significantly easier to resolve when the broker is still engaged, and the relationship with the landlord is fresh.

A broker who disappears after the deal is signed and the fee is received misses:

• The opportunity to resolve early-stage problems that would otherwise damage the tenant’s experience
• The opportunity to build a long-term relationship that generates lease renewal, brokerage and expansion transactions
• The opportunity to maintain a reputation as someone who stays through the transaction, not just to the fee

What brokers must do:

Check in at possession — confirm the space is handed over in the agreed condition. Check in at the one-month mark — confirm fit-out is proceeding without issues with the building management. Check in at the six-month mark — confirm the operational experience is meeting expectations. Set a reminder for six months before lease expiry — to initiate the renewal or relocation conversation.

These check-ins do not require significant time. They require intentionality — the decision to treat the commercial client relationship as ongoing, not transactional.

A Quick Mistake-Prevention Checklist for Commercial Brokers

Use this on every commercial leasing transaction:

Before shortlisting:

• Land use classification verified for proposed use
• OC status confirmed — not assumed
• Fire NOC current and applicable
• Total occupancy cost calculated — base rent + CAM + GST + parking + fit-out amortised
• Landlord’s GST registration status confirmed

At the LOI stage:

• All key commercial terms explicitly stated — no deferrals
• Lock-in mutual and clearly defined
• CAM charges with breakdown, cap, and audit rights
• Reinstatement obligation explicitly agreed
• Stamp duty allocation confirmed
• TDS obligation explained to the tenant

At the lease deed stage:

• Tenant’s lawyer engaged for review
• Dispute resolution clause reviewed — neutral arbitrator, correct jurisdiction
• Registration confirmed — stamp duty calculated and planned
• Pre-fit-out condition documented with photographs

Post-signing:

• Possession checked — space handed over as agreed
• OC delivered — or timeline confirmed in writing if pending
• One-month check-in — fit-out proceeding without issues
• Six-month check-in — operational experience confirmed
• Lease expiry reminder set — six months before end

What Brokers Who Avoid These Mistakes Do Differently

They treat commercial leasing as a technical discipline — not a larger version of residential practice. They verify land use before shortlisting. They calculate the total occupancy cost before presenting options. They read the lock-in clause and flag its implications before the client signs. They insist on registration. They recommend legal review as standard.

And they stay engaged after the deal closes — because they understand that the commercial client relationship does not end at the fee. It begins there.The broker who makes these choices consistently does not just close more commercial deals. They build a reputation for professional depth in a market where most brokers are operating at the surface level — and that reputation, earned one careful transaction at a time, becomes the most durable competitive advantage available.
