Leasing

Lock-in and escalation: reading the term sheet

The two clauses that decide what a Chennai office lease really costs, with the deposit, notice and GST around them.

Updated 13 Oct 2026By S N Enterprises5 min read

In short

  • Lock-ins of one to five years are usual for offices; leave early and you usually pay the rent for the rest of the lock-in.
  • Rent rises about 15% every three years, or 4–5% every year. Over six years they cost about the same.
  • Deposits run 6–12 months for Grade A offices; above three months must be written into the agreement.

The lock-in

The lock-in is the stretch neither side may end the lease. For offices it's typically one to five years. A tenant who leaves during it usually owes the rent for the rest of the lock-in. After it, either side can usually end the lease on three to six months' notice.

Ask for the lock-in to match how sure you are of your plans, not the full term: a five-year lease with a three-year lock-in is common.

Escalation

Many Chennai office leases raise the rent up to 15% every three years (a Chennai tech-park lease filed in 2019 does exactly this); others raise it every year instead, at around 4–5%.

On a rent of ₹1,00,000After 3 yearsAfter 6 years
5% every year₹1,15,763₹1,34,010
4% every year₹1,12,486₹1,26,532
15% every 3 years₹1,15,000₹1,32,250

Check whether escalation applies to maintenance (CAM) and car parks too; the agreement decides.

Deposit and notice

Grade A offices ask 6 to 12 months' rent as a refundable deposit; two recent Chennai tech-park deals settled at about six. Tamil Nadu's tenancy law makes a deposit above three months lawful only if the agreement says so, so make sure it's written in, with when and how it comes back.

GST and who pays what

  • GST at 18% applies to commercial rent when the owner is GST-registered.
  • Since 10 October 2024, when an owner who isn't registered rents to a GST-registered business, the tenant pays the GST under reverse charge (composition taxpayers were taken out of this from 16 January 2025).
  • Stamp duty and registration are usually paid by the tenant: see registering a commercial lease.

Rent-free months for fit-out and the level of maintenance charges vary building to building; there's no reliable Chennai benchmark, so ask for both in writing. The move-in cost calculator adds up the first payments.

Questions

Can we leave during the lock-in?

Only if the agreement allows it; usually leaving means paying the rent for what's left of the lock-in.

Is 15% every three years better than 5% a year?

It's cheaper in years one and two, and about the same over six years; compare the totals for your term.

Who pays stamp duty on a lease?

Usually the tenant, along with the registration fee; the deed should say.
