South Australia Commercial Security Deposit Laws
Commercial Bond Process in south australia
Negotiate Bond
Agree on bond type and amount during commercial lease negotiations.
Receive Security
Accept bank guarantee or cash bond from the tenant before occupancy begins.
Hold During Lease
Keep the bond secure for the duration of the commercial tenancy.
Release or Claim on Expiry
Return bond if no outstanding claims, or call on it if the tenant has defaulted.
Under the Retail and Commercial Leases Act 1995, commercial landlords in South Australia have specific rules governing how much security they can request and how it must be managed. These rules primarily apply to "retail shop leases" falling within the Act's scope.
Maximum Bond Amount
For leases covered by the Retail and Commercial Leases Act, a landlord can request a security bond of up to three months' rent, exclusive of GST.
If the rent increases during the lease term, the landlord can request an increase to the security bond, provided:
- At least two years have elapsed since the bond was last increased.
- The total bond amount does not exceed the current three months' rent limit.
- 60 days' written notice is given to the tenant.
Bond Lodgement
The requirements for lodging a security bond depend on whether the lease falls under the Retail and Commercial Leases Act 1995.
Retail Shop Leases
For leases covered by the Act (most retail and small commercial tenancies), cash security bonds must be lodged with the Small Business Commission.
- Landlords must lodge the bond within 7 days of receipt.
- Registered Agents must lodge the bond within 28 days of receipt.
The bond is held by the Commission for the duration of the lease. Neither party can access the funds without mutual agreement or a court order.
General Commercial Leases
For commercial leases that fall outside the Act (e.g., large-scale offices, industrial warehouses, or where rent exceeds the prescribed threshold), there is no statutory requirement to lodge the bond with any authority. In these cases:
- The bond is typically held by the landlord or their agent in a designated trust account.
- The terms for holding and releasing the bond are governed entirely by the lease agreement.
Bank Guarantees
As an alternative to a cash bond, it is very common in SA commercial leasing for the landlord to accept a bank guarantee instead. Under a bank guarantee, the tenant's bank promises to pay the landlord a specified amount on demand if the tenant defaults.
- No Statutory Cap: While the cash bond is capped at 3 months' rent, there is no legislated limit on the value of a bank guarantee. However, common practice is for bank guarantees to be between 3 and 6 months' rent.
- Return: The landlord is required to return a bank guarantee within two months after the lease expires and the tenant has fulfilled all their end-of-lease obligations (including "make good" requirements).
Returning the Cash Bond
At the end of a retail lease:
- Mutual Agreement: If both parties agree on deductions, they submit a claim form to the Small Business Commission.
- Dispute: If agreement cannot be reached, the dispute is typically resolved in the Magistrates Court, which has the jurisdiction to order the distribution of SBC-held bonds.
For leases outside the Act, bond returns follow the specific procedure outlined in the lease contract. If a dispute arises, it is handled as a breach of contract claim in the appropriate court (Magistrates, District, or Supreme Court depending on the amount).
Leases Outside the Act
For commercial leases that fall outside the scope of the Retail and Commercial Leases Act (e.g., annual rent exceeds $420,000, or the tenant is a publicly listed company), there are no statutory limits on the bond amount, no requirement to lodge the bond with the SBC, and no prescribed return timeline. Everything is governed entirely by the lease agreement.
Common Misconceptions in
Don't fall for these common myths. Know what the law actually says.
"I must always lodge a commercial bond with the Small Business Commission."
This only applies to retail shop leases under the RCLA 1995. If your lease is for a large commercial office or industrial space that falls outside the Act, you are not required to lodge the bond and should hold it in a trust account.
"A bank guarantee is subject to the 3-month cash bond cap."
No. The 3-month statutory cap only applies to cash bonds under the RCLA 1995. There is no legislative limit on the value of a bank guarantee, which is a matter for negotiation.
"Bond disputes are always handled by SACAT."
While SACAT handles many commercial lease issues, bond refund disputes for retail leases under the Act are specifically under the jurisdiction of the Magistrates Court.
Best Practices for SA Commercial Landlords
- Lodge the Bond Promptly: A 7-day lodgement window is tight. Lodge the bond with the SBC within 48 hours to avoid any compliance risk.
- Document the Property Condition: Conduct a thorough pre-lease and end-of-lease inspection with photographs and video. This evidence is critical if the bond dispute escalates to the Magistrates Court.
- Track Bank Guarantee Expiry: If a tenant's bank guarantee has an expiry date, ensure it is renewed well before it lapses. If the guarantee expires, you lose your security.
Frequently Asked Questions:
If the rent increases during the lease term, the landlord can request a proportional increase to the security bond. To do so lawfully, at least two years must have elapsed since the bond was last increased, the total bond must not exceed the current three-months-rent cap, and the landlord must provide at least 60 days written notice of the requested increase. The tenant then has time to arrange the additional funds or a top-up bank guarantee.
If a commercial tenant enters voluntary administration or liquidation, the landlord s ability to call on the bond (or bank guarantee) depends on the timing and the insolvency legislation. Bank guarantees are generally more protected in insolvency scenarios because they are a direct obligation of the tenant s bank, not of the tenant itself. Landlords dealing with insolvent tenants should seek specialist commercial legal advice immediately, as insolvency law can delay or complicate bond claims.
For retail shop leases under the RCLA 1995, bond refund disputes are resolved in the Magistrates Court. The court issues an order instructing the Small Business Commission on how to distribute the funds. For leases outside the Act, disputes are governed by general contract law and are heard in the Magistrates, District, or Supreme Court based on the claim value.
