What is the average size of a granny flat

The first factor is the size of your property. The Australian Government's National Planning Policy Framework states that granny flats should not take up more than 40% of the total area of the land on which your house is located. So, if your house is located on a 500 square metre block of land, your granny flat should not be larger than 200 square metres. This is the maximum size allowed by law.

The second factor to consider is local council zoning regulations. These regulations vary from council to council, so it's important to check with your local council before you start construction on your granny flat. Some councils have special rules in place for granny flats, so it's best to be informed before you begin any building work.

The area of your lot is the only factor that determines if you can have compliant development. If it's less than 450 square meters, then no matter how many bedrooms or bathrooms are in this secondary dwelling--it won't be considered complying with building codes and will therefore not meet accessibility standards for people with disabilities!
