Common Questions About Granny Flats
What approvals or permits do I need to build a granny flat?
For most properties, a planning permit is not required. However, you will need a building permit from your relevant municipal council. To learn more about approvals for small second homes, visit the Victoria State Government website.
Can I rent out my granny flat?
Yes, in most cases, a granny flat (small second dwelling) may be rented out, provided it meets Victorian building regulations and remains on the same title as the main home. It’s always important to check any local council requirements before proceeding.
What is the maximum size of the granny flat?
In most cases, a small second dwelling is limited to a gross floor area of up to 60 m². Final size and layout will depend on your site, block, and local building requirements.
What inclusions are required inside the granny flat?
A granny flat must be fully self-contained, including a bathroom, kitchen, doors, and all required services connected. Features such as double-glazed windows, external walls, and internal fittings may be selected to suit your independent living needs.
How much does a granny flat project cost?
The final cost will depend on your layout, range of inclusions, site conditions, structure type, and whether you select standard designs or a custom build. We work closely with property owners to create solutions that offer exceptional value.
