The Granny Flat Experts
The good news is that most granny flats can be approved through a Private Certifier, provided the property meets Complying Development Certificate (CDC) requirements. This streamlined approach reduces costs and speeds up the construction of your new granny flat. During our Site Assessment phase, we’ll confirm your property’s compliance and work with you to create a customised floor plan that suits both your needs and your site requirements. At The Granny Flat Experts, we guide you through every step to ensure a no hassle, smooth and stress-free experience.

Additional CDC Requirments to note:
What if I can't get a CDC?
-
Maximum of 1 Granny Flat is permissible per lot
-
Maximum floor area permissible for a Granny Flat is 60m2
-
Must have a 24m2 courtyard space for the Granny Flat, with an area of at least 4m wide
-
Conditions may apply if the property is in a bush fire, flood affected or heritage area
-
For battle-axe blocks, an access handle of at least 3m wide is required
-
Off-street car parking for the Granny Flat is not essential
There are other options available if your property does not meet all the requirements listed for a CDC approval. You can get your Granny Flat approved through a Development Application (DA). Development Applications are lodged to your local council. Each Council has a different Development Control Plan (DCP), meaning the rules and regulations permissible for building a Granny Flat vary across each council area. We have been dealing with development approvals for many years, and are familiar with each Council’s requirements. We can assist you throughout the entire process.
Return on Investment
A granny flat is a great way to earn additional income and in most cases is a positively geared investment. This means that the income you earn from rent is greater than the interest payable on your loan, even if you borrow 100% of the funds from your bank! Below is an example showing how you can earn over $16,000 of additional income per annum from your granny flat!
