On the Gold Coast, mapping and parking set the shape.
Granny flats on the Gold Coast are assessed as secondary dwellings under the Gold Coast City Plan. Keep the design to 80sqm of gross floor area on a standard residential lot, or around 90sqm on rural and rural residential land, and keep it subordinate to the main house. Do that and you can generally build under the accepted development pathway, with building approval through a private certifier and no development application to council. One local quirk is worth planning for. The Gold Coast typically expects an additional on-site car space for the secondary dwelling, so we work parking into the site layout early.
Where the Gold Coast gets interesting is mapping. Flood overlays are common across canal estates and low-lying suburbs from Coombabah to Carrara, and bushfire and environmental overlays touch the hinterland. If an overlay applies, or the design cannot tick every code requirement, you move into a development application. Allow roughly eight to twelve weeks with council on top of design time. Compliant sites skip that entirely, which is why we check your overlay mapping before quoting.
Renting is straightforward. Since the Queensland statewide change in September 2022, a Gold Coast secondary dwelling can be rented to anyone on the long-term market, not only family. Short-term letting is a different use with its own rules, so if Airbnb is the plan, talk to us first and we will map the pathway with council.

What will it cost on your block?
The numbers above are real ranges from completed builds. Your block decides the rest. Send us the address and we will come back with what the Gold Coast allows on it, the site costs, and the model that fits.
4 areas in this council.
High land values and high rents, which is the pairing that makes a back-yard dwelling pay for itself fastest. Access on the older canal blocks is the usual constraint.
Established blocks with depth, close to everything, and an easy run down the M1 for delivery.
Acreage in the hinterland foothills. Bushfire exposure on the treed boundaries and slope on most of the blocks.
Newer estates and rural residential side by side. Which one you are on decides whether the Family 13.5 is deliverable.
Which model fits the Gold Coast.
Six models, two widths. The 3.4m series travels without a pilot vehicle. The 4.0m series needs one.
