Why Gold Coast homeowners choose a granny flat
Across the Gold Coast, families are discovering just how much a granny flat can do. On a single existing property, it can be:
- A home for family. Keep ageing parents, grandparents or adult children close by, with comfortable, independent living of their own.
- A guest house. Somewhere private and welcoming for friends and family to stay.
- An investment property. Rent it out for additional income, with strong tenant demand right across the Gold Coast.
- Long-term value. A quality secondary dwelling adds lasting value to your home and broadens its appeal to future buyers.
It’s extra space, extra options and extra value, without the cost and upheaval of moving house.

A smart investment on the Gold Coast
For many Gold Coast homeowners, a granny flat simply makes good financial sense. A well-designed granny flat can add up to around 30% to your property’s value, and because homes with a secondary dwelling are in high demand among tenants, yours can become a reliable additional income stream.
Rental returns vary with the market, but a well-built granny flat on the Gold Coast has the potential to generate meaningful weekly rent, often enough that, over time, the flat can effectively pay for itself. As an investment in both lifestyle and long-term value, it’s hard to beat.

Gold Coast granny flat rules and approvals
Building a granny flat on the Gold Coast is often more straightforward than people expect, but there are clear rules set out in the Gold Coast City Plan. A secondary dwelling must:
- Have a maximum gross floor area of 80m², excluding patios, decks and carports
- Be the only secondary dwelling on the lot, and remain smaller than and subordinate to the main house
- Sit within 10m of the primary dwelling and share its water, sewerage and electricity connections
- Provide one additional off-street parking space and meet standard residential setbacks
- Keep total site coverage of all buildings to no more than 50% of the lot
As a general guide, your block should be at least 450m² with a minimum frontage of around 12m. On the Gold Coast, a granny flat can often be built without a development application (DA) under certain conditions, though a DA may be required where the property has significant constraints. Either way, building approval is needed through a private building certifier.
It can sound like a lot, which is exactly why we handle it for you. Our team checks what applies to your site, navigates the approvals, and liaises with Gold Coast City Council so you don’t have to.
