Granny Flats in Australia
A granny flat is usually a secondary dwelling on an existing property. Compared with tiny houses on wheels, granny flats often have a clearer approval and valuation pathway, but rules differ by state and council.
Approval pathways vary by state
NSW has a relatively clear secondary dwelling pathway for qualifying lots, while other states use different terms and restrictions. Always confirm zoning, lot size, occupancy rules, and private open space requirements.
Prefab and modular options
Some granny flats are site-built, while others use modular, prefab, or kit construction methods. Compare total installed cost and approvals support, not just the advertised build price.
When a granny flat beats a tiny house
If the goal is rental income, long-term family accommodation, or property value uplift, a compliant granny flat is often easier for councils, banks, insurers, and future buyers to understand.
