When planning a granny flat in the ACT, you must know your regulations. I have noticed these can be hard to find. So, here is a summary of rules for Granny Flats in the ACT:
A granny flat, known as a “secondary residence” in the ACT, can be anywhere from 40sqm – 90sqm. You must have a minimum land size of 500sqm and it must be in a residential zone. It must be a water sensitive urban design and suit the needs of people with disabilities. It can be rented out, but you must provide private open space for tenants plus one car parking space.
Today, I will discuss how to build a granny flat on your ACT property.

I will talk about the costs to build a granny flat in the ACT. Plus the specific regulations for a granny flat in Fyshwick.
Finally, I will provide you with a list of recommended granny flat builders in the ACT.
Compliant with the total plot ratio allowable for the block (i.e. 50% when combining the size of the house plus the secondary residence on a 500sqm lot).
In a ‘residential’ zone.
Compliant with the Australian Standard AS 4299 Adaptable Housing (Class C). That is, “easily adaptable to suit the needs of people with disabilities“. A floor plan must be submitted to your Council, showing adaptability can be attained. You may find the Australian Government’s site helpful as to what is expected.
A “water sensitive urban design” – meaning, the development achieves a minimum 40% reduction in mains water consumption. A water tank will help, they can capture almost 40%.
Compatible with exterior building materials of existing buildings in the neighbourhood.
Your “lease purpose clause” must state your land permits a specific use prior to you lodging a DA – This can checked on ACTLIS. Every search will cost $30, but is important, as if not correct before lodging a DA, you won’t be approved.
Instead, you will need to submit another application, costing $2400.
As the owner of your property, it is your responsibility to ensure there is enough space to bring in equipment.
If you build too close/over network infrastructure and mains, you are accountable for the thousands it can cost in repair work.
In 2013, changes were made to the ACT Government’s planning laws when they introduced Variation 306, allowing secondary residences to be:
Built a minimum of 40sqm to a maximum of 90sqm (previous limit being 75sqm).
This change also removed the rule that occupants must be related to the residents of the primary dwelling.
Your secondary residence must be:
In a residential zone.
On a property a minimum of 500sqm.
Design regulations include that it must:
Suit the needs of people with disabilities.
Achieve a minimum 40% reduction in mains water consumption.
Provide private open space for tenants.
Have one car parking space.
You can apply for Development Approval with your local Council, who will perform a Completeness check based on “merit”. Or, you can hire a private certifier to advise if your proposed development is exempt from development approval.
Then you can gain Building Approval and expect to pay anywhere from $100 000 – $200 000. However, do your research first, as this price excludes, amongst other things, Council fees.
