Understanding Unapproved Structures in Your South Australia Property Contract

Q: What does "Unapproved Structures" mean for a South Australia buyer?

**Unapproved Structures** refers to any building, extension, or permanent modification on a property that was constructed without the necessary development approval or building consent from the local council. In the context of a South Australia property contract, this typically involves structures like sheds, carports, pergolas, or internal structural walls that were built in violation of the *Planning, Development and Infrastructure Act 2016*. In practice, read it together with the surrounding special conditions rather than as an isolated label.

Plain English Definition

Unapproved Structures refers to any building, extension, or permanent modification on a property that was constructed without the necessary development approval or building consent from the local council. In the context of a South Australia property contract, this typically involves structures like sheds, carports, pergolas, or internal structural walls that were built in violation of the Planning, Development and Infrastructure Act 2016.

Who This Affects

Buyers negotiating or exchanging a REISA Contract who need to know how "Unapproved Structures" affects deposit and exit rights.
Sellers and agents relying on this clause to lock in (or accelerate) a sale in South Australia.
Auction or private-treaty purchasers — auction pathways often change whether cooling-off or special conditions still protect you.

The Danger Zone: Buyer's Risk

Council Demolition Orders Local councils across South Australia have the legal authority to issue enforcement notices requiring the new owner to demolish or rectify any structure built without proper authorisation, regardless of who built it.
Insurance Exclusions Most Australian insurance policies contain "illegal works" exclusions, meaning you may not be covered for fire, storm damage, or public liability claims arising from or related to an unapproved structure.
Mortgage Complications If a bank valuer identifies significant unapproved works during the finance process, the lender may reduce the property's valuation or refuse the loan entirely, putting your deposit at risk if you cannot settle.
Retrospective Approval Costs Seeking "Development Approval" after the fact is a costly process involving surveyor fees, engineering reports, and council applications, with no guarantee that the structure will be allowed to stay.
Resale Value Impact When you eventually sell, a savvy buyer’s building inspector will likely flag the unapproved structures, forcing you to either lower your price significantly or fix the issue at your own expense.
The REISA Contract Default The standard REISA Contract generally operates on the principle of caveat emptor (buyer beware), meaning if you don't identify these issues before the cooling-off period ends, you usually inherit the legal liability for them.
Safety and Compliance Hazards Structures built without oversight often bypass critical Australian Standards for fire safety, structural integrity, and electrical wiring, posing a genuine physical risk to occupants.

Key South Australia Rules

In South Australia, outcomes for Unapproved Structures are driven by the wording of your REISA Contract together with local conveyancing practice. Do not assume NSW, Queensland, or Victorian default rules apply unchanged. Before exchange, your solicitor or conveyancer should map this clause to any cooling-off rights, disclosure documents, finance or inspection conditions, and default remedies that actually appear in your paperwork.

Real-Life South Australia Scenario

Haruto, a first-home buyer in Morphett Vale, purchased a property that featured a large, modern outdoor entertaining area. After settlement, a neighbour complained to the council about drainage, leading to an inspection that revealed the pergola was an unapproved structure built too close to the boundary. Haruto was served with a council notice requiring her to either spend $12,000 on structural modifications for retrospective approval or demolish the structure entirely. Because she had already signed the REISA Contract without a specific warranty regarding council approvals, she had no legal recourse against the seller. The lesson: Always cross-reference the property's physical structures against the council's approved plans during your due diligence period.
