Granny Flats in South Australia: What Homeowners Need to Know
In the past, granny flats were named for their most common use. These backyard homes were built mainly to accommodate family elders, like grandmas. In 2023, South Australian regulations opened granny flats to the rental market. It is no longer illegal to rent out these self-contained apartments to non-family members. This has boosted the popularity of granny flats across Australia.
Before adding one of these self-contained units to your home, here is what you need to know:
Granny Flats: A Profitable Investment
Lifting family-only occupancy restrictions made these apartments more attractive as an investment. South Australian homeowners can rent granny flats to gain extra income. You can use this money for mortgage payments or other financial obligations.
These self-contained studios can also serve as a home for your adult children. Granny flats have their own entrance, bedroom, bathroom, and kitchen. So, your family can still live together while maintaining independence and privacy.
South Australian Rules and Regulations
The process of obtaining approval for granny flats is usually straightforward. Still, you cannot just build these apartments anywhere you want. There is a list of rules and regulations to follow. Under the SA Planning and Design Code, an “ancillary dwelling” is limited to a living area of 60m². This size restriction does not include verandas or carports. Anything exceeding this one-bedroom space limitation will be treated as a full second dwelling.
In most South Australian suburban zones, there are also constraints on the lot size. Usually, a minimum of 600m² is required to add a secondary dwelling. To be considered a granny flat, the unit must share utility connections with your home. This includes water, electricity, and common driveway access.
Building codes also include other aspects, such as a maximum height of 3 m. The granny flat must also be located behind the primary dwelling. It must include a private open space of at least 20m². If these requirements are not fulfilled, you will need council development approval. Going through this process on your own can be confusing. That is why you need the guidance and expertise of a reliable SA builder.
