Option to renew a lease: the notice a tenant has to give, and by when.

An option to renew gives a tenant the right to extend a lease by giving the landlord notice, usually within a window counted back from the end of the term. The right is only as good as the notice: given inside the window, in the manner the lease requires. This guide is general information about how option clauses are often written and what to check in yours. It is not legal advice. Read your lease, and ask a lawyer when the stakes are high.

What an option to renew is

An option to renew is a clause that lets the tenant extend the lease for a stated further term, or for several successive terms, on the conditions the lease sets, by giving the landlord notice. The tenant chooses whether to use it. The clause says how, by when and on what conditions, and the rent for the extra term is either fixed by the clause or set by the method it names.

The notice window

An option clause usually sets a window by counting back from the end of the term. “Not earlier than twelve months and not later than nine months before the expiration date” gives a first day and a last day. A notice inside the window is in time. A notice before it or after it may not count.

An example, not your lease: for a term ending on 30 June 2030, that window opens on Saturday 30 June 2029 and closes on Sunday 30 September 2029. Both ends of that example fall on a weekend. Whether a weekend moves a deadline is for the lease to say, so do not assume it does.

Work out both ends for your own lease with the lease notice date calculator: run it once for each end of the window.

Why missing it matters

Treat the last day as final. Do not assume a late notice will be accepted because the lease does not say time is of the essence. A late notice may leave the tenant without the right to extend: the option may lapse, and what follows depends on the lease and local law. That can mean losing the extra term and the rent that was agreed for it. Whether a late notice can be rescued depends on the lease and the law where the property is.

How to find it in your lease

These are the places to look, and what to read with the clause once you have found it.

The clause itself
Look for headings such as option to renew, renewal option, option to extend, extension option or right to renew. If the lease has a table of contents, start there; if it has a summary of basic terms near the front, check it too.
The expiration date it counts from
The window is usually counted back from the date the term ends. Find how the lease defines that date. It may be stated outright, worked out from the commencement date and the length of the term, or set by a separate memorandum of dates.
Every amendment
An amendment can extend the term, move the expiration date, change the notice period or remove the option. The window follows the latest expiration date, so read every document that changes the lease.
Conditions on the option
Many options are subject to conditions, such as not being in default when notice is given. The lease lists them, and a condition that is not met can matter as much as the date.
The rent for the renewal term
A fixed figure, a stated schedule or a method such as market rent. Know which, before you give notice.
How the notice must be given
In writing or not, to whom, at which address, by which method, signed by whom. The lease sets the manner, and a notice that is on time but given another way may not count.

What to do

Read the option clause and copy the sentence that sets the window.
Find the expiration date it counts from, and check every amendment for changes to it.
Work out both ends of the window, and the conditions that go with it.
Put the dates in your calendar with reminders, the first well before the window opens, so there is time to decide, to fix anything a condition needs, and to prepare the notice.
Give the notice in the manner the lease requires: in writing if it says so, to the named person and address, by a method it allows, signed by whoever it names.
Keep proof: a copy of the notice as sent, the proof of delivery or a receipt, the date and time it was given, and any reply.
When the stakes are high, ask a lawyer before the window closes, not after.

A spreadsheet can hold the dates: the lease date tracker template has a column for the option and the date its notice is due.

What it will not do

This guide does not tell you whether your option is valid, whether a notice you gave was in time, or what to do about a notice that is late. What binds you is your lease and the law where the property is. It is not legal advice.

Questions

What is an option to renew?

A clause that lets the tenant extend the lease for a further term, on the terms the lease sets, by giving the landlord notice. It is the tenant’s right to use or let lapse. It is different from an automatic renewal, where the lease continues unless someone gives notice to stop it.

What if I miss the window?

The option may lapse, and the lease may then run only to its current end date; what follows depends on the lease and local law. Treat the last day as final: whether a late notice can be rescued depends on the lease and the law where the property is, and you should not count on it. If you may already be late, ask a lawyer promptly.

Can I give notice before the window opens?

The clause may say "not earlier than", and a notice given before the window opens may not count. Read the first date as carefully as the last.

Does the notice have to be in writing?

A clause often says how the notice must be given: in writing, to a named person or address, by a named method. Read what yours says and follow it exactly, and keep proof that you did.

What happens after I give notice?

Read the clause. Some options set steps after notice, for example a period for the landlord to state the renewal rent, or a way to settle a rent that is to be decided. Keep a copy of your notice and any reply.

Can an amendment change the window?

Yes. An amendment can change the expiration date, the notice period or the option itself, so the window moves with it. Check every document that changes the lease before you work out the dates.

Is this legal advice?

No. This guide is general information about how option clauses are often written and what to check in yours. What binds you is your lease and the law where the property is. Read your lease, and ask a lawyer when the stakes are high.

The same clause from the landlord's side

The landlord reads the same window to know whether the space is staying. The option to renew guide for landlords shows what a landlord dates around it, and the guide to lease renewal notice deadlines shows how a window is read from a lease.
