Can You Build a Granny Flat on Your Brisbane Property?
The short answer: Most likely — but it depends on your zoning, lot size, overlays, and site constraints.
Brisbane City Council has specific requirements around:
- Maximum dwelling size
- Setbacks from boundaries
- Fire separation
- Car parking
- Flood or character overlays
- Services and infrastructure
Many homeowners assume granny flats are simple to build, but Brisbane’s varying zoning rules can make the process complex if you don’t know what to look for.
Builder Brokers handles this process for you — from preliminary feasibility and design coordination all the way to tendering your project to our panel of vetted builders.
Why Granny Flats Are So Popular in Brisbane Right Now
1. High Rental Demand
With vacancy rates near historic lows, a granny flat can significantly increase rental yield.
2. Affordable Entry Into Property Investment
Compared to buying an entire investment property, building a secondary dwelling is often more cost-effective.
3. Increased Property Value
Well-designed granny flats add long-term value through improved cash flow and broader buyer appeal.
4. Flexibility
Use it for rental income today, and for family members later. Or vice versa.
