In Tamil Nadu, a landlord cannot legally take a security deposit of more than three months’ rent for a tenancy covered by the 2017 Tenancy Act. That rule applies in Coimbatore just as it does in Chennai, although older habits of asking for large “advance” amounts still linger. This guide explains the cap, what can be deducted, how refunds work and how rent may be increased.
Key takeaways
- Security deposit is capped at three months’ rent under Section 11 of the Act.
- The deposit is refunded when the landlord gets vacant possession, less lawful dues.
- Rent cannot be raised mid-term unless the agreement allows it; otherwise three months’ written notice is needed.
- Always record the deposit, receipts and handover condition in the registered agreement.
The legal cap on deposits
The Tamil Nadu Regulation of Rights and Responsibilities of Landlords and Tenants Act, 2017 says a landlord cannot charge a security deposit exceeding three times the monthly rent. It does not set a minimum, so a landlord and tenant can agree on one or two months. Amounts beyond three months are not enforceable in the way the landlord may hope, and a tenant can raise the issue before the Rent Authority.
The cap only helps if the tenancy is documented and registered on the state portal. An unregistered agreement cannot be relied on before the Rent Authority. Our guide to rental agreements under the Tenancy Act walks through registration.
Advance, deposit and lease: know the difference
| Term | What it usually means | Legal position in brief |
|---|---|---|
| Security deposit or “advance” | Refundable amount held against unpaid rent or damage | Capped at three months’ rent |
| Advance rent | Rent paid ahead for a period | Treated as rent, record it in the agreement and receipts |
| Lease (bhogiyam or “lease amount”) | Large lump sum with little or no monthly rent, returned at the end | A different arrangement; take legal advice because it may be treated as a lease or a loan, with stamp duty and tax effects |
If you are offered a lump-sum lease on a house in areas like Vadavalli or Saibaba Colony, treat it as a significant financial transaction. Check the owner’s title and any bank loan on the property, since your money is effectively unsecured.
What can be deducted from the deposit
- Unpaid rent up to the date of handover.
- Unpaid electricity, water or maintenance bills that the tenant was responsible for.
- Repair of damage beyond normal wear and tear, such as broken fittings or holes in walls.
- Any other sum the agreement lawfully makes payable by the tenant.
Normal fading of paint, minor scuffs and ageing of fittings are part of ordinary use. The Act’s Second Schedule splits routine repairs between landlord and tenant, and your agreement can fine-tune that split.
Refund: how to make it smooth
- Do a joint inspection at move-in, with dated photos and an inventory.
- Give notice as required by the agreement and share the date you will hand over keys.
- Do a second joint inspection, compare with the move-in record and note meter readings.
- The landlord refunds the balance with a written list of deductions and bills.
If the landlord refuses to refund, or deducts amounts the tenant disputes, either side can apply to the Rent Authority for the area. The Act aims to settle such matters quickly.
Rent increases and revision
The Act leaves the rent to the parties, but it controls how rent changes. During a fixed term, rent can only be increased if the agreement expressly allows it. Otherwise, the landlord must give at least three months’ written notice of a revision. If the parties cannot agree, the Rent Authority can decide the revised rent. It is sensible to write a clear annual escalation clause, for example a fixed percentage at renewal.
Rent norms in Coimbatore
Coimbatore rents vary widely by locality, building age and amenities. A flat near IT parks on Avinashi Road or in Saravanampatti, a family house in R.S. Puram, and a showroom on a main road are priced on very different bases. Rather than rely on rule-of-thumb figures, compare similar listings, ask for the society’s maintenance charges, and factor in parking, water supply and power backup. Browse current properties for rent or office spaces to see asking levels in your preferred area.
Commercial premises
Shops, offices and showrooms covered by the Act are subject to the same three-month deposit cap. Businesses also need to think about GST on commercial rent and TDS on rent paid to the landlord, both of which your CA should review before signing.
Frequently asked questions
What is the maximum security deposit a landlord can take in Tamil Nadu?
Section 11 of the Tamil Nadu tenancy law makes it unlawful to charge a security deposit of more than three months’ rent. This applies to tenancies covered by the Act, both residential and non-residential.
When must the deposit be returned?
The deposit is refundable when the landlord takes back vacant possession, after adjusting any amount the tenant legally owes, such as unpaid rent, unpaid bills or the cost of damage beyond normal wear and tear.
Can a landlord deduct painting charges from the deposit?
Only if the agreement says so or the tenant caused damage beyond normal use. Routine repainting after years of normal living is usually the owner’s upkeep cost. Write the rule into the agreement to avoid arguments.
Does the tenant have to deduct TDS on rent?
An individual tenant not under tax audit had to deduct TDS under old section 194-IB when rent crossed ₹50,000 a month. From 1 April 2026 TDS provisions sit in section 393 of the Income-tax Act, 2025, so check current rules with your CA.
