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, Victoria now has small second dwelling rules, and Queensland leaves key development-approval questions with councils. Always confirm zoning, lot size, occupancy rules, overlays, 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.
