Why Build a Granny Flat in South Australia?
Granny flats, also referred to as dependent accommodation in SA, are a practical solution for:
Elderly parents needing proximity and support
Teenagers or young adults living at home
Families seeking extra space for guests or a home office
Enhancing property functionality and value
Unlike some other states, granny flats in South Australia are generally not allowed as separate rental investments. They must usually be used to accommodate an immediate family member and must share the same services (water, electricity, sewerage) as the main dwelling.
What Are the Rules for Building a Granny Flat in SA?
Granny flats (dependent accommodation) in South Australia are considered development and require council approval. Here are key conditions that typically apply under most local development plans:
General Requirements:
Must be for an immediate family member, not a rental investment
Must be on the same allotment as the primary dwelling
Must share utilities and services with the main home
Site & Design Criteria:
Minimum lot size: generally over 600m²
Maximum floor area:
No more than 60m², or
No more than 70% of the existing dwelling’s floor area — whichever is less
Outdoor space: At least 100m² of shared open space for both dwellings
Parking: One additional on-site parking space must be provided
Design: Must be attached to the main dwelling and built using complementary colours and materials
Please note: Each local council in South Australia may interpret or apply these rules slightly differently, so it’s important to check with your local planning authority.
Tip: Ask your council whether the additional dwelling will affect your property’s annual rates or service charges, as this can vary depending on the development’s classification.
