The commercial lease clauses that cause the most disputes are lock-in, rent escalation, security deposit refund, who pays GST and maintenance, fit-out and restoration, and the exit terms. Read those first, get every promise in writing, and make sure the agreement is written, reported to the Rent Authority and, if it runs beyond a year, registered. This checklist applies to offices, shops, showrooms and warehouses in Tamil Nadu.
Key takeaways
- Tamil Nadu’s 2017 tenancy Act applies to commercial premises (not industrial use) and requires a written agreement reported to the Rent Authority.
- Leases longer than one year must be registered under the Registration Act; stamp duty depends on term, rent and deposit.
- Lock-in, escalation, deposit refund and restoration clauses drive most of the cost risk.
- State clearly who pays GST, property tax, maintenance and utilities.
The legal basics first
The Tamil Nadu Regulation of Rights and Responsibilities of Landlords and Tenants Act, 2017 covers buildings let for residential, commercial or educational use, except industrial use. It prohibits letting without a written agreement and requires the tenancy to be reported to the Rent Authority, which issues a registration number. Separately, the Registration Act makes registration at the Sub-Registrar office compulsory for leases of more than one year or from year to year. Stamp duty and the registration fee depend on the term and the amounts payable; check the current table on TNREGINET.
Clause-by-clause checklist
| Clause | What to check | Why it matters |
|---|---|---|
| Parties and title | Owner’s name matches the title deed and tax records; any power of attorney is valid and registered | A lease from someone without authority can be challenged |
| Premises description | Door number, floor, carpet and chargeable area, parking slots, signage spots | Rent and CAM are usually billed on area |
| Term and lock-in | Total term, lock-in for each party, renewal option | Exiting during lock-in often means paying rent for the balance period |
| Rent and escalation | Start date, rent-free period, escalation percentage and frequency | Compounded escalation adds up over a long term |
| Security deposit | Amount, interest (if any), refund timeline, permitted deductions | The state Act caps deposits at three months’ rent unless the agreement says otherwise |
| Taxes and charges | GST, property tax, CAM, electricity, water, generator | Unclear wording leads to disputes |
| Use and approvals | Permitted use, trade licence and fire NOC responsibility | The premises must be approved for your activity |
| Fit-out and restoration | Approval process, what you can remove, reinstatement standard | Restoration can be costly at exit |
| Exit and default | Notice period, cure period for breach, handover process | Protects you from sudden termination |
Lock-in and term
A lock-in is the period during which neither side (or only one side) can end the lease. Landlords want long lock-ins when they spend on the building; tenants want short ones. Check that the lock-in is mutual, and that a landlord who breaches key obligations (for example, not providing power or access) cannot rely on it against you. Also check whether renewal is at your option and on what rent.
Rent, escalation and rent-free periods
Escalation clauses usually increase rent by a fixed percentage at fixed intervals. Model the rent across the whole term, not just year one. For bare-shell offices and showrooms, ask for a rent-free fit-out period and write down exactly when rent starts: on handover, on fit-out completion, or on a fixed date. Under the state Act, rent revision should follow the agreement and requires advance written notice.
Security deposit
The 2017 Act says it is unlawful to charge more than three months’ rent as deposit, save where the agreement provides otherwise, and requires the refund within one month of the tenant handing over possession, after lawful deductions. In practice commercial deposits are negotiated, so write the amount, refund timeline and a list of permissible deductions into the lease. Ask for a joint inspection at handover.
GST, property tax and maintenance
Renting commercial property is taxed at 18% GST. A registered landlord charges it on the invoice. Since 10 October 2024, if the landlord is unregistered and the tenant is GST registered, the tenant pays the GST under reverse charge; composition taxpayers were excluded from this from January 2025. Write down whether rent is quoted inclusive or exclusive of GST, and who bears it if the landlord’s registration status changes. Property tax to the local body is normally the owner’s liability; if you agree to reimburse it, say so and ask your chartered accountant how it affects the GST value. For a fuller explanation see GST on commercial rent.
Use, approvals and compliance
Confirm the building plan allows your use. A showroom in a building approved only for offices, or a warehouse on land without the right zoning, can face action from the local body. Agree who obtains the trade licence, fire safety certificate, signage permissions and power load enhancement, and who pays for them. You will also need the landlord’s ownership document and consent to register the address for GST.
Fit-out, maintenance and repairs
- Require the landlord’s consent to be “not unreasonably withheld” for interiors.
- List what stays and what you may remove at exit (partitions, AC units, generators, signage).
- Define the restoration standard: “bare shell”, “as handed over, fair wear and tear excepted” and so on.
- Split repairs clearly: structural and major repairs usually sit with the owner, day-to-day upkeep with the tenant.
Our office fit-out guide covers budgeting and timelines.
Exit, default and disputes
Check the notice period for termination after lock-in, the cure period before either side can terminate for breach, and what happens to the deposit if the landlord sells the property. Add a subletting or assignment clause if you may restructure your business. The state Act sets up Rent Authorities, Rent Courts and Rent Tribunals for tenancy disputes, and you can also agree on mediation or arbitration for commercial matters.
Before you sign
Have an advocate review the title, approvals and draft. Pay the deposit by bank transfer, register the lease if required, and keep copies of the registered deed and the Rent Authority acknowledgement. If you are still searching, browse properties for rent in Coimbatore.
Frequently asked questions
Does the Tamil Nadu tenancy Act apply to shops and offices?
Yes. The 2017 Act defines premises to include buildings let for commercial or educational use as well as homes, but excludes industrial use and certain categories such as hotels and lodging houses.
Is an 11-month commercial lease exempt from registration?
Under the Registration Act, leases up to one year are not compulsorily registrable, but the Tamil Nadu tenancy Act still requires a written agreement reported to the Rent Authority. Ask your advocate which route suits your deal.
Who pays GST on commercial rent?
A GST-registered landlord charges 18% GST. If the landlord is unregistered and the tenant is registered (and not a composition taxpayer), the tenant pays under reverse charge.
Can the deposit be more than three months’ rent?
The Act caps it at three months’ rent unless the agreement provides otherwise, so a higher figure is possible if both parties agree in writing.
