Complying Development Certificates For Granny Flats

Nothing is more frustrating than going through the expense of building an addition to your home, only to realize you’re in violation of city ordinances. Sadly, with unreputable granny flat companies sprouting up in response to the housing crisis, this is becoming a more frequently seen scenario.

You can rest assured that this will never happen with us. Unlike some of our competitors, our main priority is making sure you are completely satisfied with your granny flat, before, during, and after construction is complete.

Guidelines On Planning Approvals

Some basic rules apply for all areas, such as the size of the structure (60 square meters in Sydney), but generally permits for plumbing, electricity, and other building features will vary slightly depending on location. As our customer, you will not need to worry about making sure your structure complies; we will do all of that for you.

A few general restrictions should be observed:


Many cities require zoning permits. The only restriction is that the site on which you wish to build must be zoned for residential use. This simply means that your granny flat must be built as an addition to your home, not your commercial place of business.


In order to submit the required permits, the owner of the flat being built must also be the owner of the main residence. Although you can lease your flat, you must be the owner. Subdivision is not allowed.

We serve the cities below:

  • Sydney
  • Melbourne
  • Brisbane
  • Perth
  • Adelaide

If you have any questions about what specific requirements these cities have for your structure, please view the page for your area, or contact us directly.

Granny flat approval process in Sydney

Housing is a dominant issue in almost all countries developed ones counted in. Currently, in Australia, the property market is trending for the name ‘granny flats.’ These have been adopted widely not only in Sydney but across the country and beyond.

Aspects of doing with macro economics and affordability of housing contribute to this trend. The many benefits of having the additional property and the extra uses coming in are other reasons pushing people to go for the idea.

Alongside these reasons is the fact that the government has eased planning policies with the intention of fast-tracking the approval process to as short as 10 days. This is allowed according to SEPP legislation for affordable housing 2009. It is however just one of the approval processes you can follow.

2 types of approval processes

There are many ways of killing a rat, so they say. If you have made up your mind to construct a granny home, you have two ways to seek permission of construction.

What is mandatory is getting the legal approval. To get there, you can either follow the CDC compliance channel or take the development DA application option if you are not in a hurry. The previous is as discussed in the first paragraph usually being super-fast.

Building a granny flat is usually a fast process taking several weeks. Some people believe that planning and granny flat approvals should also go the short term way. However, the route requires your project to meet certain qualifications. If you are not lucky to meet these demands, the DA application to the local council is yet another route.

There also some rules to comply with here including state environmental planning policy and development control for secondary dwellings. The latter option is much slower and can take up to 3 months to complete.

Documents required

Some people don’t know just what is expected of them when seeking approvals. To make matters easier, you require certain key documents including;

  • Sewer diagrams – you don’t want to interfere with the sewer networks down there if you are to keep the price low.
  • 149 certificate – if you have your certificate, you will need it. If you don’t have one, then apply for one after paying a necessary small fee.
  • Title search – is it legal to build on your lot or are there restrictions or easements that can prevent that?

Having all these documents in order will give you peace of mind and a sense of direction on which approval option you are to take.

Type flats

Many people see granny flats as simple studio houses. However, there are several classifications of these including;

If your structure is not under these categories, you might need to consult further. Other structures may not require approvals such as barbeques, garden sheds etc.
