What changed

You can now rent a granny flat to anyone.

For years, Queensland restricted who was allowed to live in a secondary dwelling — in many cases, only members of the same household. That restriction was removed statewide on 26 September 2022.

Today, a secondary dwelling — a granny flat — can be rented to anyone, related or not. For homeowners that opened up a genuine income stream: a self-contained dwelling on your block that can be let long-term or short-stay, instead of sitting empty or limited to family.

The part people miss

You still need approval

The 2022 change removed the occupancy restriction — it did not remove the need to build and approve the dwelling properly. To rent a granny flat in Queensland you still need:

  • Development and building approval for the secondary dwelling
  • Council approval for your block under the local planning scheme
  • A dwelling built to the residential construction standard (NCC Class 1A)

Note: turning an existing, non-compliant granny flat into a rented tenancy can trigger a building application of its own, because rented dwellings must meet additional fire and sound-transmission requirements. Starting with a properly certified dwelling avoids that headache.

How big can it be?

Size limits are set by your council

There's no single statewide size cap — each local council sets its own. Many Queensland councils allow a secondary dwelling up to around 80m², though some regional councils differ. Setbacks, site cover and parking rules also vary.

The Forge 12's footprint sits comfortably within typical limits, but the golden rule applies everywhere: check your local council's planning scheme before you commit. If you tell us your block, we can help you understand what's likely to apply.

Why this is easy with a Forge 12

Built to the standard the rules require

The reason renting trips people up is almost always the build: a caravan or non-compliant tiny home can't meet the residential construction standard, so it can't be approved as a rentable secondary dwelling. The Forge 12 is different — it's certified NCC Class 1A, the same classification as a house, and delivered with a full certification pack.

That means once it's approved on your block, it can be legally rented — long-term or short-stay — and insured as residential property. Model the income on our rental calculator, or see the full cost breakdown.
