Granny Flat & Secondary Dwelling Approvals
Logan City Planners
Thinking of Building a Granny Flat or Second Dwelling in Logan?
A granny flat, secondary dwelling or tiny home can provide extra accommodation, house family members or make better use of a larger property.
Under the Logan Planning Scheme, a secondary dwelling is a self-contained dwelling on the same lot and under the same ownership as the main house. It can be attached or detached. Logan City Council
Do Granny Flats Need Council Approval?
Not always.
Secondary dwellings are typically accepted development where they comply with the planning scheme requirements. If they do not comply, a Development Application may be required. Building approval from a private certifier is still required. Logan City Council
Common issues include:
- Building setbacks
- Site coverage and building height
- Lot size
- Flooding
- Bushfire and environmental constraints
- Sewer and other infrastructure
- Whether the proposal is actually a secondary dwelling, auxiliary unit or dual occupancy
Logan also applies a maximum secondary dwelling size of 70m² on residential lots under 1,000m², or 100m² otherwise. Infrastructure charges also apply.
What About Tiny Homes?
Tiny homes are not automatically exempt from planning requirements.
If a tiny home is used as a permanent residence, Council will consider how it fits within the relevant residential use. Where it sits alongside an existing house, it may potentially fall within the secondary dwelling provisions.
The use, size, location and property zoning all matter.
Secondary Dwelling or Dual Occupancy?
This distinction is important.
A secondary dwelling remains part of the main dwelling house use and cannot be separately titled. If you are proposing two more independent dwellings, Council may instead consider the proposal as an auxiliary unit or dual occupancy, which has different requirements.
