Tips for Your Granny Flat in Tasmania

Check your local council zoning — most states allow granny flats on lots 450sqm+ but setback and coverage rules vary.

Kit/prefab granny flats are 20–30% cheaper than custom builds and can be completed in 8–12 weeks vs 14–20 weeks.

A well-designed granny flat can add $100,000–$200,000 to your property value and generate $300–$600/week in rental income.

Ensure separate metering for electricity and water if you plan to rent the granny flat — this simplifies tenant billing.

Consider orientation carefully — north-facing living areas maximise natural light and reduce heating and cooling costs.
