Selling a Property with Unapproved Structures
Unapproved building work — decks, extensions, carports, granny flats built without council approval — is more common than most people think. If you're selling, here's what you need to know.
How Common Is It?
Very common. Common unapproved structures include:
- Enclosed patios and verandahs
- Carports and sheds over the size threshold
- Bathroom/kitchen additions
- Raised decks
- Granny flats and secondary dwellings
- Swimming pool fencing non-compliance
Your Options
1. Regularise Before Selling
- Apply for retrospective building approval
- Cost: $3,000–$15,000+ depending on complexity
- Benefit: Clean sale, no buyer concerns
- Risk: Council may require modifications
2. Disclose and Sell As-Is
- Disclose known unapproved work in the contract
- Buyer accepts the risk (usually at a discount)
- Your legal obligation is to disclose known issues
3. Remove the Unapproved Structure
- Sometimes the simplest option
- Eliminates the issue entirely
- Cost of removal vs. cost of regularisation
Impact on Development Sites
For development site sales, unapproved structures are generally irrelevant — the developer plans to demolish everything. Focus on the site's zoning and development potential rather than existing building compliance.
