A commercial lease can shape a business for years. Rent is only the beginning: outgoings, reviews, fit-out obligations, repair costs, personal guarantees, options and make-good requirements can materially change the real cost of the premises. An experienced commercial lease lawyer Adelaide based can identify those risks before you sign, negotiate clearer terms and help resolve a dispute if the relationship later breaks down.
O’Dea Lawyers assists South Australian tenants and landlords with commercial lease reviews, drafting, negotiations, renewals, assignments, defaults and disputes. We focus on what the document means in practice: what must be paid, who carries each risk, what happens if plans change and how the lease supports the commercial deal.

Commercial lease advice for Adelaide tenants and landlords
A useful lease should do more than record a rent and an address. It should allocate responsibility clearly, reflect the agreed deal and provide workable answers when circumstances change. The right advice therefore depends on which side of the transaction you are on and what the premises need to achieve.
Advice for commercial tenants
For a tenant, a lease review is a form of business-risk review. We can explain the total occupancy cost, identify obligations that continue after the keys are returned and negotiate protections for matters such as landlord works, fit-out access, approvals, delays, business sales and renewal rights. The objective is not simply to change legal wording. It is to make sure the lease works with your operating model, finance, licences and plans for growth or exit.
Advice for commercial landlords
For a landlord, careful drafting protects the asset and makes the lease easier to administer. The document should accurately capture the premises, permitted use, rent, recoverable outgoings, security, maintenance responsibilities, approval processes and remedies. It should also comply with any mandatory retail-leasing rules that apply. Clear documents and consistent records can reduce enforcement problems and make a future sale or refinancing smoother.
Why obtain a commercial lease review before signing?
Commercial leases are usually drafted for a long relationship, but problems often begin before the lease does. A tenant may sign a heads of agreement without making the deal conditional on planning approval. An incentive may be described in emails but omitted from the lease. A landlord may assume that a tenant must replace ageing air-conditioning equipment when the repair clause does not say so. These issues are much harder to renegotiate after documents are signed, fit-out money has been spent or trading has begun.
A commercial lease agreement lawyer should compare the draft lease, disclosure statement, heads of agreement, plans, incentive deed and fit-out documents as one transaction. A clause that looks acceptable alone may conflict with another document. Dates also need to align: access, commencement, rent commencement, practical completion, option deadlines and expiry can each have different consequences.
Legal review does not replace financial, tax, planning, building or technical advice. It helps coordinate those questions and records the agreed allocation of risk in enforceable documents.
Does the Retail and Commercial Leases Act apply?
The title of South Australia’s Retail and Commercial Leases Act 1995 (SA) can be misleading. It does not automatically govern every lease of business premises. Its core application is to a qualifying “retail shop lease”, including premises where goods are sold to the public by retail or services are provided to the public, subject to the statutory definitions and exclusions.
From 1 September 2025, the Retail and Commercial Leases Regulations 2025 (SA) prescribe an annual-rent threshold of $420,000 excluding GST. Rent above the threshold is one reason the Act may not apply, but it is not the only test. The premises, use, term, parties, rent and any specific exclusion must all be considered. The application of the Act can also change during the lease in some circumstances.
Where the Act applies, it imposes rules that may override inconsistent lease wording. Among other things, it deals with pre-lease documents, disclosure, certain capital expenditure, lease-preparation costs, security, minimum terms, rent reviews, outgoings, assignments, some shopping-centre practices and dispute resolution. Where it does not apply, the negotiated contract assumes even greater importance, although other legislation and general legal principles may still affect the parties.
Do not assume that a warehouse, office, consulting room, hospitality venue, salon or mixed-use premises is automatically inside or outside the Act. A retail lease lawyer in Adelaide can assess the particular lease rather than relying on the label used by the agent or landlord.
Before signing heads of agreement
Check whether the premises can support the business
A lease does not itself guarantee that a proposed business is lawful, financially viable or technically possible at the site. Before committing, investigate the permitted use and any planning approval, building classification, liquor or industry licences, signage rules, disability-access requirements, fire and safety systems, power and data capacity, grease traps, ventilation, loading, waste arrangements, customer access and parking. For strata or community-titled property, relevant by-laws may also restrict use or fit-out.
If an approval, finance, franchise consent or technical report is essential, the transaction may need an express condition and a realistic deadline. A general conversation with an agent is not a substitute for a properly drafted condition.
Treat the heads of agreement seriously
Heads of agreement are often intended to record commercial terms before the full lease is prepared. Whether all or part of the document is binding depends on its wording and the circumstances. Confidentiality, exclusivity, access, costs or deposit provisions may be binding even where the main leasing terms are not. Avoid signing or paying money until you understand the effect of the document and any withdrawal consequences.
The heads should address more than face rent. Important items include the parties and any guarantors, premises and car parks, term and options, reviews, incentives, outgoings, permitted use, exclusivity, landlord works, fit-out access, commencement triggers, security, insurance, make-good and conditions precedent.
Pre-lease disclosure for a qualifying retail shop lease
If the Act applies, the lessor or agent must provide a prospective lessee with a proposed lease after negotiations begin and before the lease is entered into. The South Australian Small Business Commission’s retail and commercial leasing guide must be supplied at the same time. A signed disclosure statement must also be given before the lease is entered into.
The disclosure statement records important information such as the premises, permitted use, term, access, availability for occupation, base rent, reviews and monetary obligations. Shopping-centre disclosures include further details. The document is not merely a formality: it should be checked against the lease, plans and negotiated deal. Missing, inconsistent, incomplete or materially misleading information can have significant consequences.
The South Australian Small Business Commission’s leasing information is a useful starting point, but it cannot assess the risks of a particular transaction.
Commercial lease review Adelaide: clauses to examine
1. Parties, premises and permitted use
The correct legal entity must be named. A newly formed company, trustee, partnership or franchisee may require different drafting and execution. Plans should show exactly what is leased and what is shared, including storage, car parks, outdoor areas, loading zones and access routes.
The permitted-use clause should be broad enough for current operations and foreseeable changes without undermining planning or the landlord’s tenancy mix. A narrow description can restrict new products, online fulfilment, ancillary services or a future sale of the business. Any exclusivity should state precisely what is protected, where it operates, its exceptions and the remedy for breach.
2. Term, commencement and renewal options
Confirm the initial term, option periods and each relevant date. “Commencement” may mean execution, access, handover, practical completion or the day rent starts; unclear definitions create avoidable disputes. If the landlord must complete works, the lease should explain the standard, evidence and consequences of delay.
For a retail shop lease governed by the Act, the aggregate term is generally required to be at least five years, but statutory exceptions apply, including certain short-term arrangements and properly certified exclusions. The five-year rule should never be applied without checking the particular facts.
An option is valuable only if it can be exercised correctly. The lease may require written notice within a strict window and may make exercise conditional on there being no specified breach. Diarise the opening and closing dates well in advance. Where an option rent is current market rent and the Act applies, the tenant may have a statutory opportunity to request an early market determination before the option deadline.
3. Base rent, GST, incentives and payment timing
Check whether figures include or exclude GST, when invoices are issued, the payment method, any interest on late payment and whether rent is payable during access or fit-out. Budget for the full occupancy cost rather than the advertised rent.
Rent-free periods, fit-out contributions and other incentives should be documented consistently. An incentive deed may include repayment or “clawback” obligations if the lease ends early or is assigned. Those obligations can survive termination and materially affect the cost of exit, so the triggers and calculation need close review.
4. Rent-review mechanisms
Common methods include fixed percentages, fixed amounts, CPI-based changes and current-market reviews. Model the likely rent across the whole term and option periods. Check the CPI definition, reference quarter, rounding, notice process and what occurs if a review is late.
For a retail shop lease covered by the Act, mandatory restrictions apply to changes in base rent. Certain clauses that let a party select the highest of multiple methods are void. If a market-review method can produce a decrease, a provision preventing that decrease may also be void. Market-rent disputes may proceed to valuation under the statutory or contractual process. A commercial lease lawyer can check whether the proposed formula is lawful and commercially workable.
5. Outgoings and other occupancy costs
Outgoings can include council rates, water charges, insurance, cleaning, security, common-area maintenance, management costs and other building expenses. The lease should identify recoverable items, the tenant’s proportion, the accounting period, the estimate and reconciliation process, and rights to supporting information. Review exclusions and capital expenditure separately.
Under the Act, a tenant is not liable for retail-shop outgoings unless the lease specifies what is recoverable, how it is calculated and apportioned, and how it may be recovered. The lessor must also provide prescribed estimates and information. The Act restricts recovery of land tax from a lessee, subject to the application of the relevant provisions and any transitional rules. Non-retail leases may allocate costs differently, making the written definition especially important.
6. Fit-out, landlord works and access
Fit-out documents should state what each party will design, approve, construct and pay for. Address access dates, building rules, contractors, approvals, services, hoardings, defects, delays and removal at expiry. A tenant should understand whether rent starts even if approvals are delayed or the premises cannot yet trade.
If the landlord has works to complete, attach a detailed scope rather than relying on broad promises. Specify objective completion requirements and what happens if works are late or defective. Record the condition of the premises at handover with dated photographs, plans and a condition report; those records may later be central to a repair or make-good dispute.
7. Repairs, maintenance and legal compliance
Do not assume “structural” and “non-structural” allocate every responsibility. The lease should deal with the roof, walls, floor, plumbing, electrical systems, air-conditioning, lifts, fire equipment, grease traps, plate glass, pests and damage. It should distinguish routine servicing, repair, replacement and capital upgrades.
Compliance clauses can transfer the cost of new laws or authority requirements. Consider whether the obligation arises from the tenant’s specific use, its fit-out, the general condition of the building or a pre-existing defect. The Act restricts certain capital-expenditure obligations in covered retail leases, but that protection should not be assumed to resolve every repair question.
8. Insurance, indemnities and damage
Check required policies, coverage limits, interested-party requirements and when certificates must be provided. Indemnities and releases should be read with the insurance clauses so there is no uninsured gap. Consider who bears business-interruption losses and what happens to rent if the premises are damaged, inaccessible or unusable. Covered retail leases have statutory provisions concerning damaged premises; other leases depend more heavily on their wording.
9. Security deposits, bank guarantees and personal guarantees
Security provisions should identify the amount, form, issuer, expiry requirements, top-up obligations and circumstances in which the landlord may draw. A personal guarantee can expose a director’s or other guarantor’s assets even though the tenant is a company. Negotiations may address caps, time limits, replacement guarantors or release following an assignment.
For leases governed by the Act, security-bond rules apply and a lessor who receives a bank guarantee must generally return it within two months after the tenant completes the secured obligations, subject to matters such as pending court proceedings. The end-of-lease process should therefore document handover, keys, make-good, final accounts and any unresolved claim.
10. Assignment, subletting and changes in control
A tenant may need to transfer the lease when selling the business, restructuring or bringing in an investor. Review consent requirements, information to be provided, landlord costs, guarantees and release of the outgoing tenant. A prohibition on a change in corporate control can capture transactions that are not described as an assignment.
For a covered retail shop lease, the Act limits the grounds on which consent to assignment may be withheld and requires an assignor’s disclosure process. The statutory steps and timing must be followed carefully. Outside the Act, the lease and general law determine the consent process.
11. Relocation, demolition and redevelopment
Relocation or demolition can interrupt trade and strand fit-out expenditure. Examine the trigger, notice, evidence of a genuine proposal, alternative premises, new-lease terms, moving costs, fit-out costs, rent during closure and termination rights. The Act supplies minimum protections for certain relocation clauses in retail shopping centres, but negotiated protections can still be important.
12. Make-good, reinstatement and end-of-lease obligations
Make-good is often negotiated at the beginning and priced at the end. A broad clause may require removal of the fit-out, services and alterations; repair of resulting damage; repainting; replacement of flooring; professional cleaning; and reinstatement to an earlier configuration. It may apply even where the landlord plans to redevelop.
Define the required condition and relevant baseline. Attach a condition report, identify items that may remain, address fair wear and tear, and create an inspection and works process before expiry. Tenants should obtain early estimates. Landlords should issue instructions consistently with the lease and preserve evidence of the premises’ condition and reasonable rectification cost.
Drafting a commercial lease for a landlord
Landlord drafting should begin with the commercial deal and the property, not a generic precedent alone. The lease must identify the asset accurately, preserve necessary management rights and provide a practical system for approvals, payment, inspection, repair and enforcement. It should also reflect mortgagee requirements and any strata, community-title or shopping-centre arrangements.
Before issuing documents, a landlord should confirm whether the Act applies and prepare the required leasing guide, disclosure statement and outgoings material. Proposed incentives and landlord works should be documented with the lease. Once signed, the landlord needs an administration calendar for reviews, option and expiry notices, insurance certificates, reconciliations and guarantee expiry dates.
- Use the correct ownership entity and an accurate premises plan.
- Make rent, outgoings and review calculations objectively workable.
- Set clear consent processes for fit-out, signage, assignment and alterations.
- Match repair, compliance and make-good obligations to the building and deal.
- Ensure default and security clauses can be administered lawfully.
Commercial lease disputes in South Australia
Commercial lease disputes can threaten cash flow, premises access and business continuity. Early advice is particularly important after a default notice, lockout threat, bank-guarantee demand, option rejection, relocation notice or urgent repair failure. A party should preserve its rights without taking steps that create a separate breach.
Common lease disputes
- Unpaid rent, outgoings, interest or incentive repayments
- Incorrect rent reviews or disputed market valuations
- Repair, maintenance, water ingress or air-conditioning responsibilities
- Fit-out delays, defects and failure to complete landlord works
- Refusal of consent to assignment, sublease or alterations
- Option exercise, expiry and renewal disputes
- Drawdown of security or claims against guarantors
- Relocation, demolition, access and quiet-enjoyment issues
- Make-good, reinstatement and dilapidation claims
- Termination, re-entry and relief against forfeiture
A practical resolution pathway
A commercial lease dispute lawyer will usually start by identifying the operative documents, chronology, alleged breach, evidence and immediate commercial objective. The next step may be a carefully framed response, a proposal to remedy, document exchange, negotiation or a without-prejudice settlement conference. Technical evidence from a valuer, accountant, engineer, building consultant or quantity surveyor may be needed.
For disputes concerning a retail shop lease, a party may apply to the South Australian Small Business Commission for alternative dispute resolution. The Commission can facilitate resolution of disputes arising from or related to the lease or occupation of the premises. If a binding determination is required, the Act gives the Magistrates Court powers that include restraining breaches, requiring compliance, awarding compensation in appropriate cases and reinstating forfeited rights. Different forums and remedies may apply to leases outside the Act.
Do not stop paying rent, withhold keys, draw security, change locks or assume a lease has ended without advice on the specific documents and law. Urgency can affect the remedies available.

Frequently asked questions about commercial leases
When should I engage a commercial lease lawyer?
Ideally, obtain advice before signing heads of agreement, paying a non-refundable amount or beginning fit-out. Early review gives you more scope to negotiate the permitted use, conditions, incentive, landlord works, security and exit terms. If documents are already signed, advice can still clarify obligations and identify the safest next step.
What does a commercial lease lawyer check?
A review commonly covers the parties, premises, term, options, permitted use, rent and reviews, outgoings, fit-out, repairs, compliance, insurance, security, guarantees, assignment, relocation, default, termination and make-good. The lawyer should also compare the lease with the heads, disclosure statement, plans and incentive documents.
Is a heads of agreement legally binding?
It depends on the wording and circumstances. Some heads are intended to be non-binding except for selected clauses; others may create enforceable obligations. Conduct after signing can also matter. Have the document reviewed before signing rather than assuming its title determines its effect.
Does every South Australian commercial lease have a five-year minimum term?
No. The general minimum five-year rule applies to qualifying retail shop leases under the Act, and exceptions exist. A lease outside the Act is not given a five-year minimum merely because it is commercial. The premises, use, rent, term and any exclusion must be assessed.
What is the retail-lease rent threshold in South Australia?
From 1 September 2025, the prescribed threshold is $420,000 in annual rent excluding GST. A lease may fall outside the Act while rent exceeds that amount, subject to the detailed statutory provisions. The threshold alone does not establish coverage, and it should be checked against the current regulations.
Can a tenant negotiate a commercial lease?
Yes. The landlord may decline a proposed change, but many commercial terms are negotiable. Priorities often include conditions, permitted use, incentives, review mechanisms, outgoings exclusions, landlord works, security, assignment, option rights and make-good. A focused request usually works better than treating every clause as equally important.
Who pays the landlord’s lease-preparation costs?
The answer depends on whether the Act applies and what has occurred. For a covered retail shop lease, the Act limits the tenant’s liability for the landlord’s preparation and registration costs and requires supporting accounts. Different consequences can apply if a person enters negotiations and later withdraws. Non-retail leases may allocate costs under their own terms.
Can a landlord recover land tax and other outgoings?
For leases governed by the Act, recoverable outgoings must be properly specified and the Act restricts recovery of land tax, subject to application and transitional provisions. For other commercial leases, the agreed wording is critical. In every case, check the list of charges, allocation method, estimates, reconciliations and information rights.
What happens if I miss the deadline to exercise an option?
The landlord may not be obliged to renew if the option was not exercised in the required manner and within the specified period. Do not assume reminders or prior discussions preserve the option. Obtain urgent advice, check all notices and communications, and consider whether another legal or negotiated pathway is available.
Can I assign my lease when I sell the business?
Usually only through the consent process in the lease and any applicable legislation. The buyer may need to provide financial and business information, and disclosure documents may be required. Check whether the outgoing tenant and guarantors will be released; an assignment does not automatically eliminate every continuing liability.
How can a make-good dispute be reduced?
Start with precise drafting and a reliable condition report. Before expiry, inspect the premises, identify disputed items, obtain scopes and quotes, and record any agreement about work the landlord does not require. Leaving the issue until the final days can increase cost and reduce practical options.
How are retail lease disputes resolved in South Australia?
Parties often begin with direct negotiation. A party to a retail shop lease may apply to the South Australian Small Business Commission for alternative dispute resolution. The Magistrates Court has statutory powers to resolve covered disputes, and substantial monetary matters may be referred to the District Court in specified circumstances. The appropriate process depends on urgency, the remedy sought and whether the Act applies.
Do I need a solicitor for a lease agreement?
Independent legal advice is strongly recommended for a commercial lease, even where the agent describes the document as standard. A solicitor can identify obligations that may not be apparent from the rent summary, check whether mandatory legislation applies and negotiate terms before the business commits to the premises.
How much does a commercial lease review cost?
Cost depends on the length and complexity of the documents, the value and term of the deal, whether the Act applies, the number of negotiation rounds and the urgency. Ask for a written scope covering what will be reviewed, whether negotiations are included and what work would be additional.
