This page answers some of the most common questions we receive about building a granny flat. Got another question for us? Don’t hesitate to get in touch.
The NSW SEPP states the block must be 450m2. We recommend for you to read our ‘No Council Approval’ page for further details on other minimum criteria.
Yes, this may be possible via a local council Development Application, however different local council areas have varying guidelines.
No, current regulations state that regardless of the size of your block, you may only build one granny flat on your property.
The maximum size that a granny flat can be built is 60m2.
Yes, these items do not form part of the 60m2 granny flat.

We can build it either attached or detached from the main dwelling.

A Complying Development Certificate (CDC) is issued by a private certifier, rather than your local council and is assessed against the state government legislation. In 2009, the NSW Government released the Affordable Housing State Environment Planning Policy (SEPP) which permits all residential home-owners to build a granny flat on their property. Your property must be larger than 450m2, have a minimum of 12m street frontage and also meet a number of set criteria. For more information about a CDC, please click here.
A DA is a Development Application which is lodged through your local council to get your granny flat approved. A DA specifies the design, structural elements, location and timeframe in which the development should occur.
Yes, if your property is between 900-1500m2 you can still build a granny flat via a complying development. However, the setbacks will change to 1.5m for side setback and 5m for the rear setback. Under a DA and depending on your local council, these setbacks can possibly be relaxed upon application.
Yes, you can build a granny flat on a rear sloping block, however, we will need to find a suitable stormwater solution. Depending on the extent of the slope, the method or design used to create a solution will change. Additionally, each local council may have a different solution required.
A BAL refers to the Bushfire Attack Level. This is used for establishing the requirements for construction to improve the protection of the building elements from a bushfire attack. For a granny flat to be built, the requirement is to be BAL 29 or lower.
Everyone’s situation is different, and we recommend you talk with our sales team or in-house mortgage broker for advice on when to apply for a loan.
To process a CDC Application, it takes as little as 10 weeks including design, documentation, submission and approval. To process DA, this process takes on average 4-6 months from design, documentation and submission, however each council have their own timeframes.
Yes. Your granny flat will have Home Owners Warranty insurance for the duration of construction. Backyard Grannys also has a workers compensation insurance policy and a public liability insurance policy all ensuring you are protected.
Home Owners Warranty Insurance protects the homeowner if the builder suddenly is unable to complete the project.
