What Is a Commercial Lease? Key Terms and Legal Basics

Signing a lease can feel like a big “we’re doing this” moment for your business.

Whether you’re opening your first shopfront, moving into a warehouse, setting up a studio, or taking a small office for your startup team, the lease you sign will shape your costs, risk, and flexibility for years.

So if you’re asking what is a commercial lease, you’re already thinking like a smart business owner. A commercial lease isn’t just paperwork - it’s a long-term deal that can either support your growth or make it harder than it needs to be.

Below, we’ll break down what a commercial lease is (in plain English), what’s usually inside one, and what you should look out for before you commit.

What Is A Commercial Lease (And How Is It Different From A Residential Lease)?

A commercial lease is a legally binding agreement where a landlord lets you (the tenant) use a property for business purposes in exchange for rent and other payments, for an agreed period of time.

In practice, a commercial lease sets out:

• What space you’re renting (and what you can use it for)
• How long you can occupy it (and renewal options)
• How much you pay (rent, outgoings, increases)
• Who is responsible for repairs, maintenance, and insurance
• What happens if things change (assignment, subleasing, early exit, default)

Commercial leasing is different to residential leasing because the rules, protections, and negotiation norms are not the same.

Commercial Leases Are Usually More “Negotiable” (But Also More Risky If You Miss Something)

Residential leases tend to be more standardised and heavily regulated.

Commercial leases can be much more flexible - which is great when you negotiate the right terms - but it also means the lease might shift more risk onto your business if you sign without fully understanding it.

“Retail Lease” Vs “Commercial Lease”

In Australia, you’ll often hear two terms:

• Commercial lease: a broad category covering many business premises (offices, warehouses, industrial units, studios, consulting rooms, and more)
• Retail lease: a type of commercial lease that applies where the premises are used for certain retail activities (for example, a shop in a shopping centre)

This distinction matters because retail leases often come with extra legal protections and disclosure requirements (which vary by State and Territory). In NSW, for example, retail lease arrangements can be affected by the Retail Leases Act.

If you’re not sure whether your lease is “retail” or not, it’s worth clarifying early - it can change what rights and processes apply.

What Does A Commercial Lease Usually Cover?

Commercial leases can vary a lot, but most follow a similar structure. Here are the clauses that typically matter most for small businesses and startups.

1. The Term, Options, And Renewal

The term is how long the lease runs (for example, 3 years). Many leases also include an option to renew (for example, one further term of 3 years).

This is important because your lease term affects:

• how stable your location is (especially if foot traffic matters)
• how bankable your business looks to lenders/investors
• how long you’re financially “locked in”

Renewal timing is also critical. Leases often require you to exercise an option within a strict window. If you miss that window, you might lose the right to renew.

It’s also worth thinking ahead about lease renewal notice periods (even if you’re not in QLD, the concept is the same: timing and process can make or break your renewal).

2. Rent, Rent Reviews, And Incentives

Rent isn’t always just “a weekly price”. Your lease may include:

• Base rent (weekly/monthly)
• GST (often added on top, depending on the landlord’s GST registration and the lease)
• Rent review mechanism (fixed percentage increases, CPI, or market review)
• Incentives (rent-free period, fitout contribution, or reduced rent for the first months)

It’s common for landlords to offer incentives, especially in competitive markets. The key is making sure the incentive is clearly documented and doesn’t come with unexpected “clawback” provisions if you exit early.

Note: The tax treatment of rent, GST and incentives can be complex and will depend on your circumstances. This is general information only - it’s worth speaking to your accountant for tax advice before you sign.

3. Outgoings (The Hidden Cost That Catches Many Businesses)

Outgoings are costs relating to the property that the tenant may have to pay in addition to rent. Examples can include:

• council rates
• water rates
• strata levies (if applicable)
• building management fees
• land tax (sometimes, depending on the lease and state or territory rules)
• insurance premiums

Outgoings can significantly change your real occupancy cost, so it’s worth requesting an estimate or previous year’s outgoings before you sign.

Note: The way outgoings (including items like land tax) can be recovered from tenants varies by lease and by state or territory, and there may be tax implications. This is general information only - consider getting advice from your lawyer and accountant.

4. Make Good And Fitout

Many leases include a make good clause, which usually means you must return the premises to a particular condition at the end of the lease.

This can be one of the biggest “surprise” costs in a commercial lease.

Make good might require you to:

• remove your fitout
• repair any damage
• repaint the walls
• replace flooring
• reinstate ceilings, lighting, or partitions

Before agreeing, think about what your space will need to operate (signage, shelving, consulting rooms, reception, storage), and how expensive it would be to undo it later.

5. Repairs, Maintenance, And Insurance

Commercial leases usually set out who is responsible for different categories of repairs and maintenance.

Be careful here - responsibility can range from “landlord pays for structural repairs” to “tenant pays for almost everything”. If your business uses specialised equipment (for example refrigeration, extraction systems, heavy machinery, or clinical fitout), you’ll also want clarity about maintenance obligations.

Insurance is another key area. For example, many business owners ask who should cover building insurance and related risks - and the answer often depends on what the lease says and how the property is set up. It’s worth understanding building insurance responsibilities before you sign, not after something goes wrong.

What Are The Main Types Of Commercial Leasing Arrangements?

When people ask “what is a commercial lease?”, they’re often also trying to work out what kind of arrangement they’re entering.

Here are a few common structures you might come across.

Lease Vs Licence (And Why It Matters)

A lease generally gives you a right to exclusive possession of the premises for the lease term, subject to the lease conditions.

A licence is often more flexible and may look like a “permission to occupy” rather than a traditional lease (for example, some co-working or shared space arrangements).

Licences can work well for early-stage startups that want flexibility, but they can also offer less security of tenure.

If you’re entering a shared workspace or similar arrangement, a Property Licence Agreement can be a better fit than a standard lease - the important thing is making sure the document matches what you’ve been promised in practice.

Gross Lease Vs Net Lease

Commercial leases are often described as gross or net (sometimes with variations in between).

• Gross lease: outgoings are usually included in the rent (or the landlord pays most outgoings)
• Net lease: you pay rent plus outgoings (sometimes described as a “net, net, net” lease where the tenant pays the majority of property-related expenses)

There’s no universally “better” option - what matters is that you understand your total occupancy cost and can budget for it.

Head Lease And Sublease

Sometimes you’ll lease directly from the landlord (a head lease). Other times, you may lease from an existing tenant (a sublease), which introduces extra moving parts:

• you may be bound by both the sublease and the head lease conditions
• your rights can be affected if the head tenant breaches their lease
• you might need landlord consent for the sublease

If you’re considering a sublease, it’s worth getting clarity on how termination, make good, and access rights work in the chain of documents.

What Should You Negotiate Before Signing A Commercial Lease?

Many small business owners assume commercial leases are “take it or leave it”. In reality, it’s common to negotiate - especially where you have a good business case, multiple location options, or a landlord keen to secure a stable tenant.

Here are practical points that can have a big impact on your day-to-day operations.

Permitted Use (So You Can Actually Run Your Business)

Your lease will usually contain a permitted use clause describing what activities you can carry out at the premises.

This sounds simple, but it can create real problems if it’s too narrow.

For example, you might start as “retail clothing” but later want to add alterations, online order fulfilment, small workshops, or a coffee cart. If your permitted use doesn’t allow it, you may be in breach - or stuck having to renegotiate later.

Fitout, Signage, And Approvals

If you need to modify the premises (even minor changes), check:

• whether landlord consent is required
• who pays for approvals
• what happens to the fitout at the end of the lease
• what signage is allowed (and where)

Also consider timing. If you have a launch date, you’ll want realistic handover and fitout periods built into the deal.

Assignment And Subleasing (Flexibility If Your Business Changes)

Startups evolve quickly. Even established businesses can outgrow a space (or downsize).

That’s why clauses about assignment (transferring the lease to someone else) and subleasing (leasing part or all of the space to another tenant) matter more than people expect.

Common questions to ask include:

• Do you need the landlord’s consent to assign or sublease?
• Can the landlord refuse consent (and on what grounds)?
• Will you remain liable even after assignment?
• Are there fees for processing consent?

Personal Guarantees And Security

Many landlords ask for security such as:

• a cash bond
• a bank guarantee
• a director’s personal guarantee

These can be standard, but they’re also a key risk point for founders - especially personal guarantees, which can expose your personal assets if the business can’t meet lease obligations.

If the landlord requires a personal guarantee, it’s worth understanding the scope (for example, does it cover all obligations? does it continue after an assignment? is it capped?).

What Happens If You Need To Leave Early Or There’s No Lease Signed?

This is where many business owners get caught out - because the “best case” plan is that everything goes smoothly, but good planning also covers the “what if” scenarios.

Can You Break A Commercial Lease?

In many cases, you can leave early only if:

• the lease has a negotiated break clause, or
• you reach an agreement with the landlord (often documented as a surrender), or
• you assign the lease to a replacement tenant (with landlord consent), or
• there’s a legal basis to terminate (which can be complex and fact-dependent)

Leaving without following the lease process can expose you to costs such as unpaid rent for the remainder of the term, make good costs, and the landlord’s losses.

Because this is such a common pain point, it’s worth understanding the practical risks around breaking a commercial lease agreement before you sign one in the first place (so you can try to negotiate flexibility upfront).

Ending The Lease The “Normal” Way

Even when you finish a lease at the end of the term, you’ll often need to manage:

• notice requirements
• make good obligations
• handback condition reports
• bond or bank guarantee release

Sometimes a landlord may issue a notice asking you to vacate or dealing with a breach scenario. If that happens, you’ll want to move quickly and understand your position. The rules can vary based on what kind of lease you have and what state you’re in, but the concept of a notice to vacate is an example of why timing and process matter so much in commercial leasing.

What If You’re Occupying A Space Without A Signed Lease?

This happens more often than you’d think - for example, you move in based on email negotiations, or you start trading while the landlord is “finalising the lease”.

Trading without a signed lease can create uncertainty about:

• how long you can stay
• how rent increases work
• who pays for repairs and outgoings
• what notice period applies if either party wants to end the arrangement

Even if it feels like a short-term convenience, it can become a serious business risk. If you’re in that situation, the issues around no lease agreement arrangements are worth addressing early (ideally before you invest in fitout, marketing, or staff for that site).

Key Takeaways

• A commercial lease is a legally binding agreement that sets the rules for how your business can occupy and use a premises, and what you must pay and maintain.
• Commercial leases often include key clauses around term, options to renew, rent reviews, outgoings, make good, repairs, and insurance - and these can significantly affect your cash flow.
• Retail leases are a specific type of commercial lease and may have additional legal protections depending on your state and the nature of your business.
• Negotiating permitted use, fitout rights, assignment/sublease flexibility, and security (like guarantees) can make a major difference to your risk and ability to grow.
• Plan for “what if” scenarios early, including whether you can exit the lease, assign it, or what happens if you occupy a premises without a signed document.
