A commercial lease option to renew is a contractual right that lets a tenant extend their lease for a further term, usually by giving the landlord written notice within a set window before the current term ends. It does not happen automatically.
The tenant must exercise it correctly and on time, or the right can be lost. Getting the timing and the wording right is what keeps your business on its premises, and the sections below explain exactly how to do it across Australia.
How Does an Option to Renew a Commercial Lease Work?
An option to renew gives you, the tenant, the right to extend your commercial lease for a further fixed term once the current term ends, provided you give proper notice and meet the conditions in your lease. The option belongs to you, not the landlord.
A landlord does not have to include an option when the lease is first negotiated, but once it is in the lease and you exercise it correctly, the landlord is generally bound to grant the further term.
You will often see options written as “3 + 3” or “5 + 5”, which means an initial term followed by one or more further terms of the stated length.
The key point many tenants miss is that the renewal is not automatic and the further term is usually documented as a fresh lease or a deed of renewal, not just a continuation of the old one.
What Notice Period Do You Have to Exercise the Option?
The notice period is set by your individual lease, so there is no single national deadline that applies to every commercial tenancy.
Most leases require you to give written notice within a defined window before the current term expires.
Common windows are three to six months, six to twelve months, or three to nine months before the expiry date.
Your clause will usually be phrased as something like “not more than six months and not less than three months before the expiry date”, which creates both an earliest and a latest date to act.
The safest approach is to read your clause as soon as you sign, then diarise both the opening and closing dates of the window with reminders well in advance.
How Do You Exercise the Option Correctly?
You exercise the option by giving the landlord clear written notice that unequivocally states you are taking up the further term.
The notice should identify the lease, the premises, the landlord and the tenant, and it should be signed by the tenant named in the lease rather than an agent acting informally.
Avoid conditional notices, such as saying you will renew only if the landlord agrees to a certain rent or completes works, because a notice that is not clear and unconditional can be rejected.
Check how your lease says notice must be delivered, as some clauses allow email while others require post or hand delivery to a specific address.
In the 2011 New South Wales Supreme Court decision in Kavia Holdings Pty Ltd v Suntrack Holdings Pty Ltd, the court accepted that an email could satisfy a requirement for notice in writing, but you should never assume this without checking your own clause.
Always keep proof that the landlord received your notice inside the window, because a posted letter may be treated as received several days after you send it.
Why Is Timing “Of the Essence” for an Option to Renew?
For options to renew, time is treated as being of the essence, which means the deadline is strict and even a notice served one day late can be ineffective.
Australian courts consistently interpret option windows strictly and will not usually rescue a tenant who serves notice outside the permitted period.
In Tripple A Pty Ltd v WIN Television Qld Pty Ltd [2018] QCA 246, the Queensland Court of Appeal confirmed that a landlord cannot waive the requirement to exercise the option within the set timeframe once that timeframe has already passed.
The practical effect is that a late attempt to renew does not create a renewal in law, and any deal reached afterwards is treated as the negotiation of a brand new lease.
This is why the deadline matters far more than most tenants expect, and why acting early is always safer than leaving it to the final week.
What Conditions Must You Meet Before Exercising the Option?
Most option clauses set preconditions that you must satisfy before you can validly exercise the option.
These conditions are usually strict, and failing even one can invalidate your notice.
Common preconditions include:
- No unremedied breach of the lease at the time you give notice
- Rent paid up to date
- Outgoings and other money owed under the lease paid in full
- Compliance with any other covenants the lease specifically ties to the option
If you are behind on rent or in breach when you serve your notice, the landlord may be entitled to reject the renewal, so it is wise to tidy up any issues before the option window opens.
What Happens to Your Rent When You Renew?
The rent for the renewed term is almost never simply carried over because it is reset using the review method written into your lease.
The three most common methods are a fixed percentage increase, a Consumer Price Index adjustment, or a market rent review carried out by an independent valuer.
Market rent reviews cause the most disagreement because the landlord and tenant can hold very different views on what the premises are worth.
The table below compares how each method works and what it means for your budgeting.
| Review method | How the new rent is set | Predictability for the tenant | Common dispute risk |
| Fixed percentage | Rent rises by a set percentage, such as 3 to 4 per cent, at each review | High, because the figure is known in advance | Low |
| CPI adjustment | Rent moves in line with the Consumer Price Index | Moderate, because it depends on inflation | Low to moderate |
| Market review | Rent is reset to current market value, often by an independent valuer | Low, because the figure is unknown until determined | High, due to valuation disagreements |
Many commercial leases contain a ratchet clause, which prevents the reviewed rent from falling below the rent you were already paying, so a market review can only hold rent steady or push it higher.
Retail leasing legislation limits this in several states, and both New South Wales and Western Australia make clauses that stop a market rent review from decreasing the rent void, so a ratchet clause may not apply if your lease is a retail shop lease.
If your renewal triggers a market review, it helps to gather evidence of comparable rents early and to understand how the lease appoints a valuer if the parties cannot agree.
Knowing which method applies before you commit to renewing lets you decide whether staying is still the right commercial choice.
What Happens if You Miss the Option Window?
If you miss the option window, the right to renew generally lapses and the landlord is not obliged to grant you a further term.
A late notice will usually not create a renewal, and the landlord may either negotiate a new lease on fresh terms or ask you to leave.
This can be a serious blow to a business that has invested in fit-out, built up local goodwill, or relies on the location to trade.
Losing the option does not always mean immediate eviction, but it does mean you lose the certainty and the bargaining position the option was meant to give you.
Can You Get Relief if You Exercise the Option Late?
Relief for a late exercise is possible in limited situations, but it is rare and should never be relied on as a safety net.
Courts have generally held that equity does not relieve a tenant who simply fails to exercise an option to renew in time, especially where the landlord did nothing to cause the delay.
In some cases, tenants have succeeded using the unconscionable conduct provisions of the Australian Consumer Law, but those outcomes turned on unusual facts and cannot be assumed.
In Queensland, the Property Law Act 2023, which commenced on 1 August 2025, lets a tenant apply to the court for relief where the tenant has exercised an option but the landlord seeks to refuse the renewal because of a breach or a formal defect in a notice that was given on time.
This relief does not rescue a notice given after the option window has closed, because the timing of the option notice is treated separately from those formal requirements.
Even where relief may be available, court proceedings are costly and uncertain, so meeting the deadline remains far cheaper and safer than fighting to be excused for missing it.
What Does Holding Over Mean for Your Tenancy?
Holding over is when you stay on the premises after the lease ends without having validly renewed, usually on a month to month basis.
During a holdover, the tenancy is often on the same terms as the old lease, but the rent may increase, and either party can usually end the arrangement on short notice, with the exact notice period depending on your lease and the law in your state.
This gives you flexibility, but it removes the security of a fixed term, leaving your business exposed to a notice to vacate.
Holding over can be a useful bridge while you negotiate, but it is a weaker position than a properly exercised option, so it should be a fallback rather than a plan.
How Do the Rules Differ for Retail Shop Leases in Western Australia?
In Western Australia, most retail shop leases are regulated by the Commercial Tenancy (Retail Shops) Agreements Act 1985, which adds tenant protections on top of what the lease itself says.
The Act generally applies to premises with a lettable area of 1,000 square metres or less that are used for retail, and it does not cover shops above that size or leases held by publicly listed companies and their subsidiaries, subject to the Act’s exact definitions and exceptions.
Under the Act, landlords must give tenants written notice of the date on which an option to renew is no longer exercisable, and the tenant should receive this notice between six and twelve months before that date.
If the landlord fails to give this notice, the option expiry date may be extended, which offers retail tenants a measure of protection that ordinary commercial tenants do not have.
The Act also gives most retail tenants an entitlement to a minimum tenancy of up to five years, worked out on the assumption that available options are taken up.
You can read more about how the Act treats options on the Western Australian Small Business Development Corporation’s Commercial Tenancy Act page.
If your Western Australian premises are not a retail shop, your lease is governed only by its own terms and general contract law, so there is no statutory reminder and the option deadline is entirely up to you to track.
Other states run their own retail leasing systems, and Victoria and Queensland also require landlords to remind retail tenants of the option deadline, while New South Wales does not, so the exact protections depend on where your premises are located.
How Can Tenants and Landlords Protect Their Position at Renewal?
The single most effective step is to read the option clause the day you sign the lease and record every key date, rather than discovering the deadline in the final weeks.
Diarise the earliest and latest dates to give notice, add reminders months ahead, and confirm how your lease requires the notice to be delivered.
Before the window opens, clear any rent arrears, settle outstanding outgoings, and fix any breaches, because these are the issues landlords most often use to reject a renewal.
Getting your lease reviewed early also lets you plan for the rent review, weigh the cost of staying against moving, and negotiate better terms while you still hold the option as leverage.
Security of tenure matters because premises are often central to how a business trades, and with 2,729,648 actively trading businesses recorded in Australia at 30 June 2025, according to the Australian Bureau of Statistics, competition for good locations is real.
The same figures show a 13.9 per cent business exit rate over 2024-25, a reminder that losing a well-placed premises at the wrong moment can put real pressure on a business.
For landlords, the lesson is the opposite side of the same coin, because clear option clauses, accurate records, and timely notices reduce the risk of costly disputes over whether an option was properly exercised.

Frequently Asked Questions
How much notice do I need to give to exercise a commercial lease option to renew?
The notice period is set by your lease, not by a fixed national rule. Most leases require written notice between three and twelve months before the term ends, often a window of three to six months or six to twelve months before expiry. Always check your exact clause and diarise both the earliest and latest dates.
What happens if I miss the deadline to exercise my option to renew?
If you miss the option window, the right to renew usually lapses and your landlord is not obliged to grant a further term. Courts read these deadlines strictly, and a late notice will generally not create a renewal. You may still negotiate a new lease, but you lose the certainty the option gave you.
Can my landlord refuse to renew if I exercise the option correctly?
If you exercise the option strictly in line with the lease and meet every condition, the landlord is generally bound to grant the further term and cannot refuse. Disputes usually arise only where the tenant was in breach, had unpaid rent, or served notice late or in the wrong form. Correct, on-time notice protects your right.
Does the rent stay the same when I renew a commercial lease?
Usually not. The rent for the renewed term is reset using the review method in your lease, such as a fixed percentage rise, a CPI adjustment, or a market rent review. Many leases also include a ratchet clause, which means the reviewed rent cannot fall below what you currently pay. Check how your rent is calculated.
Do I need to sign a new lease when I exercise an option to renew?
Often yes. Exercising the option usually creates a binding agreement for a further term, and the landlord will prepare a new lease or a deed of renewal to document it. Registration rules vary by state, but in New South Wales, for example, a lease longer than three years, including any option period, generally must be registered to fully protect your interest in the premises.
Are the options to renew the rules different for retail shop leases in Western Australia?
Yes. Most retail shop leases in Western Australia fall under the Commercial Tenancy (Retail Shops) Agreements Act 1985, which adds protections beyond the contract. Landlords must tell tenants the date an option is no longer exercisable, and most tenants gain a minimum five-year term. Non-retail commercial leases are governed only by the lease and general law.
