Granny flats have grown in popularity as a way to accommodate larger families, generate extra cash from rentals, or just make better use of backyard space.
However, it’s crucial to comprehend the granny flat approval process before starting construction, particularly if you wish to prevent expensive delays or legal issues.
Obtaining the necessary approvals is the first step, regardless of whether you’re designing a self-contained investment property or a cosy home for ageing parents.
Everything you need to know is covered in this guide, including how to get council approval for granny flats, how much it costs to get approved, and whether hiring a private certifier could expedite the process.
Why Are Granny Flat Approvals Necessary?
A granny flat is governed by building and planning codes since it is regarded as a secondary residence.
These permits guarantee that the building complies with local zoning regulations and is safe and livable. You might have to stop construction, pay fines, or even have the building demolished if you don’t have the right approvals.
Obtaining approval also gives your construction legitimacy, which is crucial if you ever plan to sell the property or lease it out.
When Does a Granny Flat Need Council Approval?
One of the most frequent queries from homeowners is: Does a granny flat require council approval?
Generally speaking, the answer is yes, particularly if your property does not meet your state’s or territory’s Complying Development Certificate (CDC) requirements.
For example, in New South Wales, granny flats can frequently be constructed without obtaining full council approval provided that :
- The property is at least 450 square metres.
- The apartment is no more than 60 square meters.
- The lot has a single primary residence.
- The development conforms to floor space ratios, height restrictions, and setbacks.
Should your project not meet these requirements, you will have to submit a Development Application (DA) to your local council, which can be a more involved and drawn-out procedure.
Using a Private Certifier for Granny Flats
Instead of using the council’s channels, more and more homeowners are choosing to use a private certifier for granny flats.
Throughout the building process, a private certifier can review your plans, provide a Complying Development Certificate, and conduct work inspections.
Using a private certifier has the following advantages:
Quicker approvals: Compared to councils, they are able to issue certificates faster.
Simplified communication: Throughout the process, you only interact with one contact.
Professional advice: Certified professionals are knowledgeable about state and local laws.
But it’s crucial to confirm that your certifier is licensed and accredited in accordance with state laws.
Comprehending the Cost of Granny Flat Approval
The cost of approval varies based on your location, the kind of approval you need, and whether you apply through the council or a private certifier.
An overview of the usual granny flat approval fees in Australia is provided below:
| Item | Estimated Cost (AUD) |
| Private Certifier Fees | $1,500 – $3,000 |
| Development Application (DA) Fee | $500 – $2,000 (Council Dependent) |

| BASIX Certificate (NSW Only) | $200 – $500 |
| Surveys, Reports & Other Documentation | $1,000 – $3,000 |
These numbers are merely estimates that could change depending on the site’s complexity or the requirements of your local council.
Typical Mistakes to Avoid
Consider the following possible problems before submitting your plans:
Inaccurate classification of the site: Additional reports and approvals might be needed for a site that has heritage overlays, bushfire zones, or flood risk.
Failure to adhere to height and setback requirements: Even minor infractions may result in rejection or expensive adjustments.
Absence of expert assistance: Your project may be delayed if you attempt to oversee the procedure without the assistance of an architect, planner, or certifier.
How to Obtain Approval for a Granny Flat
This is a condensed synopsis of the procedure:
Evaluation of the Site: Verify that your property satisfies the zoning and size requirements.
Design & Planning: Create compliant plans by collaborating with experts.
Select the Approval Route:
- CDC through a private certifier if your property is eligible.
- For complex or non-compliant builds, DA through the local council.
Obtain Relevant Certificates : Acquire the necessary BASIX, construction, fire safety, and other certificates.
Commence Construction : Only after all necessary approvals have been obtained can construction start.

Always seek advice from knowledgeable experts, conduct thorough research, and never take short cuts when obtaining approvals. You will ultimately experience less stress if you invest the time and money up front.
