Option to Renew a Lease in NSW: Notice Windows and the Mistakes That Cost Tenants

Key Points

  • If you miss the deadline in your option clause, you will usually lose the right to renew.
  • Your notice must follow the lease exactly: in writing, unconditional, sent to the right person and by an allowed method.
  • A past breach of the lease doesn't automatically cancel your option, but some leases are drafted to prevent options being exercised for past breaches.

An option to renew a lease in NSW gives you, the tenant, the right to stay for a further term. But that right only works if you exercise it within the time, and in the way, your lease requires. Miss the window or get the notice wrong, and you can lose the right to renew.

This article explains how to find your option notice period, how to exercise the option properly, what happens if you have breached the lease, and what to do if the deadline has passed.

What is an option to renew a lease in NSW?

An option to renew (sometimes called an option to extend) is a right in your lease to take a further term. A lease described as “3 + 3”, for example, has an initial three-year term and an option for three more years.

The choice is yours. If you exercise the option properly, the landlord is generally bound to grant the further term, usually on the same terms except for the rent, which is often reviewed.

Retail or non-retail lease: why it matters

The Retail Leases Act 1994 (NSW) applies to many retail shop leases and overrides conflicting lease terms. If you have an option to renew a retail lease in NSW at market rent, you can ask for the new rent to be worked out early. The request must be made between six and three months before the last day for exercising the option (shorter periods apply to leases of 12 months or less). You then have 21 days after being told the rent in writing to decide.

For other commercial premises, such as offices and warehouses, that Act does not apply. Your rights come mainly from the lease, and you may have to commit before you know the new rent.

How to find your option notice period

Your option notice period (the option window) is usually in the lease’s schedule or the option clause. It is often stated as a period before the lease ends, such as “not more than six months and not less than three months before the end of the term”.

Check:

  • Work out the exact dates. Count from the end date stated in your lease, not from when you moved in.
  • Check for a first date as well as a last date. Some leases set the earliest day the option can be exercised, so a notice sent too early can also cause problems.
  • Diarise both dates, with a reminder well before the window opens.

Don’t rely on your landlord or agent to remind you. The deadline in your lease is the one that counts.

How to exercise an option to renew a commercial lease

To exercise an option to renew a commercial lease, you give the landlord written notice within the option window. Courts generally expect the notice and its delivery to comply with the lease.

What your notice of exercise of option should say

Your notice of exercise of option should:

  • be in writing and dated;
  • name the landlord and tenant exactly as they appear in the lease;
  • identify the premises and the lease;
  • state clearly that you exercise the option for the further term; and
  • be signed by the tenant, or by someone authorised to sign for it.

Keep it unconditional. A notice that says you will renew “subject to agreeing the rent”, or that you “would like to discuss renewing”, may not count as exercising the option.

Serving the notice correctly

Check both the option clause and the general notices clause. These often say where and how notices must be sent, such as by post, by hand or by email.

Use a method your lease allows, send it to the right person at the right address (including any new address the landlord has given you), and keep proof of delivery.

If you’re unsure, get lease advice before the window closes.

What if you’ve breached the lease?

Many option clauses say you can only exercise the option if you have not breached the lease, for example by paying rent late. That doesn’t mean a past breach automatically cancels your option. Even so, fix any breach, such as rent arrears, before you send your notice.

Under the Conveyancing Act 1919 (NSW), a breach generally can’t stop you exercising the option unless the landlord gives you a formal notice, within a short period, setting out the breach and saying it intends to treat the breach as preventing the option. For a breach that happened before you exercised the option, that period is 14 days after your notice.

If you receive one of these notices, act quickly. You can apply to the Supreme Court for relief, but the time limit is short, and serious or deliberate breaches may count against you. If your landlord is relying on a breach of contract, get advice straight away.

Missed the option to renew your lease? What happens next

If the option window has closed, you have generally lost the right to renew. Your lease will end on its end date unless you and the landlord agree otherwise.

Before you assume the worst, check:

  • whether the deadline really has passed, using the exact wording of your lease;
  • for a retail lease, whether an early rent determination moved the deadline; and
  • what the lease says about staying on after it ends (holding over). Many leases allow a month-to-month arrangement, which either party can end on short notice.

You can still ask the landlord for a new lease, but they don’t have to agree. Get advice before you write to them, as what you say can affect your position.

If the landlord disputes that you exercised the option, the issue can often be resolved through negotiation or mediation. If not, it may need to go to court.

Frequently asked questions

What happens if I miss the deadline to exercise my option?

You will generally lose the right to renew, and the lease ends on its end date. The landlord may offer a new lease but does not have to. Get advice promptly, in case the deadline was miscalculated.

Can I exercise my option by email?

It depends on your lease. If the notices clause allows email, it is generally fine. Courts have sometimes accepted email even where the lease didn’t mention it, but that turned on the wording of the particular lease. The safest approach is to use a method your lease clearly allows, and email a copy as well.

Can my landlord refuse my option because I’ve breached the lease?

Not automatically. In NSW, the landlord must give you a formal notice about the breach within a short time after you exercise the option. If it does, you can apply to the Supreme Court for relief, but you must act quickly.

Can I find out the new rent before I exercise my option?

For many retail leases with a market-rent option, yes, by asking for an early rent determination within the window explained above. For other commercial leases, it depends on your lease and what the landlord will agree to.
