How To Sublease Your Business Premises

Thinking about subleasing part (or all) of your business premises? Whether you’re downsizing, in between moves, or want to offset rising rent, subleasing can be a smart way to reduce costs while keeping your lease obligations on track.

There are, however, some important legal steps to follow in Australia. Your head lease will set out what you can and can’t do, your landlord may need to consent, and you’ll want a robust sublease in place to protect your position if things go wrong.

In this guide, we’ll step you through how a commercial sublease works, what to check in your current lease, the subleasing process from start to finish, key clauses to negotiate with your subtenant, and the documents you’ll need to do it properly.

What Does Subleasing Your Business Premises Mean?

Subleasing is when you (the head tenant) grant a new lease to a third party (the subtenant) for some or all of your leased space. You remain a tenant under your original lease and continue to owe obligations to your landlord, but you also become a landlord of sorts to your subtenant under the sublease.

It’s different from assigning your lease. An assignment transfers your entire interest in the lease to a new tenant, and the incoming tenant deals directly with the landlord (usually via a Deed of Assignment of Lease). With a sublease, you stay in the middle: you still pay rent to your landlord and collect rent from the subtenant.

There’s also a third arrangement called a licence to occupy. This can suit short-term or flexible arrangements where exclusive possession isn’t granted (for example, desk space or shared facilities), often documented via a Property Licence Agreement. The right structure for you depends on your head lease terms, the space and fit-out, and how long you want the arrangement to run.

Subleasing can deliver real benefits-reduced holding costs, better use of unused rooms, and a smoother transition if you’re scaling down. The trade-off is extra admin and risk: you’ll manage another legal relationship and need to ensure the subtenant’s conduct doesn’t put your head lease at risk.

Can You Sublease Under Your Current Lease?

Your starting point is always the head lease. Commercial and retail leases typically include clauses dealing with subletting. Some allow subleases with landlord consent, others restrict them to certain conditions, and a few prohibit them entirely.

Key things to look for in the head lease:

• Sublease clause: Does the lease allow subleasing? Is landlord consent required? Are there conditions (for example, minimum rent, no partial sublease, subtenant quality tests)?
• Use of premises: Will the subtenant’s proposed use fit within the permitted use in your head lease?
• Term alignment: The sublease term must end before (or on) the expiry of your head lease, including options. No sublease can outlast your own lease.
• Outgoings and utilities: Does your lease specify how these are charged and whether you can on-charge a proportion?
• Fit-out and alterations: Are you allowed to make changes or let a subtenant make changes? What approvals are required?
• Make-good obligations: Consider how the sublease will deal with end-of-term reinstatement and who pays.

If the premises is a retail shop, state-based retail leasing laws often set rules about when a landlord can refuse consent to a sublease, and may impose disclosure obligations. For example, the Retail Leases Act (NSW) contains specific requirements around assignments and subleases, consent, and disclosure. Each state and territory has its own retail legislation, so it’s important to understand the rules that apply in your location.

Outside of the lease itself, also check planning and zoning, building rules, and any strata or centre rules. The subtenant’s business must be lawful in the premises and compliant with centre or building policies (for example, trading hours, signage, or waste disposal).

Step-By-Step: How To Sublease Your Premises

Subleasing isn’t difficult when you break it down. Here’s a practical, step-by-step process to follow.

1) Confirm Your Subleasing Rights

Read your lease closely for subleasing clauses and any preconditions (for instance, that you aren’t in default). Note any timelines for seeking consent and the documents you must provide with your request.

2) Define The Space And Use

Decide whether you’re subleasing the whole premises or a defined part. If it’s part, have a plan to delineate it (e.g. a scaled plan attached to the sublease) and consider shared areas like reception, kitchens and bathrooms.

Make sure the proposed use fits your head lease “permitted use” and any building or centre rules. If necessary, talk to the building manager about access or after-hours use early to avoid surprises later.

3) Find And Vet Your Subtenant

Treat this like you’re the landlord. Check the subtenant’s financials, business references and trading history. If they’ll be operating a retail business, consider their brand compatibility and fit-out plans.

4) Seek Landlord Consent Early

Landlords usually require a formal consent request with details about the subtenant, the proposed sublease terms, the area, and the intended use, plus supporting documents (financials, IDs, plans). Build in time for this step-consent can take weeks.

In retail contexts, landlords are generally not supposed to unreasonably withhold consent (subject to the specific legislation in your state). Expect conditions such as being up to date on rent, payment of the landlord’s legal costs, providing a bank guarantee or bond, and using the employer’s or centre’s standard consent form.

5) Draft And Negotiate Your Sublease

Use a tailored Commercial Sublease Agreement that mirrors key obligations in your head lease and fills the gaps that matter between you and the subtenant (rent split, outgoings, access, fit-out, and default processes). Remember, if your subtenant breaches the sublease and the landlord takes action against you, you’ll want clear rights to recover your losses from the subtenant.

6) Agree On Security

Landlords commonly require security from tenants; it’s sensible for you to do the same. Typical options include a cash bond, a personal guarantee, or a bank guarantee. If you’re taking a bank guarantee, make sure the terms align with the sublease and the landlord’s consent deed-our guide to Bank Guarantees explains the basics. If the subtenant’s directors will guarantee performance, be mindful of the risks on both sides-see our overview of Personal Guarantees.

7) Get The Consent Deed Signed

Consent is often documented in a deed signed by all parties (landlord, tenant and subtenant). It typically confirms the landlord’s consent and sets conditions (for example, minimum insurance, no variations without consent, and step-in rights). Keep this document safe-it’s evidence you did the sublease properly.

8) Finalise Insurance, Fit-Out And Access

Check that the subtenant has the insurances required by your head lease (public liability, plate glass, workers compensation) and that you’re noted as an interested party if appropriate. Manage any fit-out approvals through the landlord’s process and confirm practical matters like keys, alarm codes, after-hours access and waste removal.

9) Handover And Ongoing Management

Do a condition report with photos at handover. Agree on how you’ll manage maintenance requests and compliance inspections. Decide whether the subtenant pays you directly or reimburses their share of outgoings based on invoices you receive from the landlord.

10) Keep An Eye On Compliance

Your head lease obligations continue. Diary dates for rent, outgoings, renewals and options, and monitor the subtenant’s performance. If they default, act quickly under the sublease so you can remedy any knock-on issues with your landlord before they escalate.

Key Terms To Negotiate With Your Subtenant

A strong sublease sets clear rules so everyone knows where they stand. Key terms to consider include:

• Rent And Outgoings: Will rent be a fixed amount, a percentage of your head rent, or market-based? Decide how you’ll apportion outgoings (for example, pro-rata by floor area, or actual usage for utilities) and how you’ll reconcile them.
• Bond Or Guarantee: State the amount and form of security (cash bond or bank guarantee), where it will be held, and the conditions for drawing on it.
• Term And Options: Ensure the sublease expiry falls before your head lease expiry. If you have an option on your head lease, consider whether you’ll offer an aligned option in the sublease (noting you must validly exercise your own option first).
• Permitted Use: Keep it within the head lease permitted use and note any restrictions (noise, odours, signage, trading hours).
• Repairs And Maintenance: Set out who handles routine maintenance, compliance checks (e.g. fire services) and repairs for exclusive and shared areas.
• Fit-Out And Alterations: State approval processes, who pays, and restoration obligations on exit.
• Insurance And Indemnities: Mirror head lease requirements and include appropriate indemnities and waivers to reflect the practical risks in the premises.
• Default And Termination: Include practical default notice periods, step-in rights, and termination rights that track your head lease. If you lose your head lease (for example, early termination), the sublease will usually end-make sure this is clear.
• Access And Shared Facilities: Spell out access hours, security procedures, parking, lifts, loading docks, cleaning, and any service level expectations for shared spaces.
• Make-Good: Align end-of-term make-good with your head lease and decide who pays for reinstatement (full, partial, or none).

Getting these points right up front reduces disputes later. If you’re unsure what’s market standard in your area or building type, a quick Sublease Review can highlight risks and help you negotiate a fair deal.

What Legal Documents Will You Need?

Every sublease arrangement is a little different, but most will require some combination of the documents below. Where possible, align terms with your head lease so you’re not caught between conflicting obligations.

• Commercial Sublease Agreement: The core contract between you and the subtenant setting out the area, term, rent, outgoings, use, insurances, maintenance, default and make-good. A tailored Commercial Sublease Agreement is the best way to manage risk.
• Landlord Consent Deed: Confirms consent and sets any landlord conditions. Often tripartite (landlord, tenant, subtenant).
• Security Documents: A bank guarantee or cash bond deed; if directors are guaranteeing performance, a short-form guarantee and indemnity. See background on Bank Guarantees and Personal Guarantees.
• Plans And Fit-Out Approvals: An annexed floor plan depicting the subleased area and any shared spaces, plus any landlord-approved fit-out drawings and conditions.
• Insurance Certificates: Certificates of currency evidencing the subtenant’s required policies and noting parties as required.
• House Rules/Centre Rules: These may be referenced or attached to ensure the subtenant understands building procedures, deliveries, signage and safety.
• Alternative Forms: In some cases, a short-term or flexible occupancy is better documented as a Property Licence Agreement rather than a lease-particularly if you don’t want to grant exclusive possession or a fixed term.

A well-prepared bundle makes landlord consent smoother and sets your sublease up for success. If the landlord provides their own templates, check that they dovetail with your head lease and the sublease you’ve negotiated.

Key Takeaways

• Subleasing lets you reduce costs by granting a new lease to a subtenant while you remain on the hook under your head lease-so your sublease must protect you if things go wrong.
• Start by checking your lease for subletting clauses, permitted use, approval processes and any restrictions; retail premises may be impacted by the Retail Leases Act (NSW) or similar legislation in your state.
• Get landlord consent early and in writing, then put a tailored Commercial Sublease Agreement in place that mirrors key head lease obligations.
• Negotiate clear terms on rent and outgoings, security (bond, bank guarantee or guarantees), repairs, insurance, access, default rights and make-good to avoid disputes.
• Align all documents-consent deed, sublease and security-so your rights and responsibilities are consistent from top to bottom.
• If you only need a short-term or shared-space arrangement, consider using a Property Licence Agreement instead of a lease.
