Let’s clear up the most common myth first. A kit home is still a real home, so yes, it needs the same approvals as any other house. The word “kit” describes how it is supplied and built, not a shortcut around the rules. The good news is that the process is well worn, and once you understand the pieces it is far less daunting than it sounds. Here is how it works.
The three approvals you will hear about
Most residential builds move through some combination of these:
- DA (Development Application): council assesses your proposal on its merits. It is flexible, so you can propose most things, but it is slower and can be refused. Timeframes commonly run 60 to 120 days.
- CDC (Complying Development Certificate): a faster path through a private certifier, often around 20 days, but only if your design meets every rule. Miss one and you start again as a DA, so it pays to get this call right.
- CC (Construction Certificate): the sign-off that says your final plans meet the standards, and you can begin building. This usually follows a DA.
Which path suits you depends on your block, your design and your council, and choosing correctly at the start saves months.
It varies by state
The framework is national, but the details differ. NSW runs a three-tier system of exempt development, CDC and DA. Victoria separates planning permits from building permits, and many projects need both, in that order. Queensland uses a Material Change of Use application where required, then building approval through a private certifier, often on the quicker end at 10 to 20 days. Wherever you are, always confirm the specifics with your local council or a certifier before you lodge anything.
The reports and certificates you will likely need
Approval is not just a set of drawings. A typical submission also includes a site plan, engineering drawings, a soil or contour report, an energy or BASIX assessment (BASIX in NSW), stormwater plans, and a bushfire (BAL) report if your block is bushfire prone. Heritage, flood and coastal overlays can add more, and they extend both time and cost.
What it costs and how long it takes
As a rough guide for 2026, a NSW CDC might run around $2,500 to $6,000 over about 20 days, while a full DA plus Construction Certificate can be $3,000 to $15,000 or more over 60 to 120 days. Queensland approvals often sit lower and faster. These are ballpark figures, and overlays or a tricky site will move them.
A note for owner-builders
If you plan to build it yourself, the approval pathways are the same as for a licensed builder. What changes is the owner-builder licensing and insurance side, which varies by state, so it is worth checking your obligations early.
How we make this easier
This is the part that stops a lot of people before they start, so it is exactly where we help most. At Mana Kit Homes we assist with compiling the documents required for your certification, including guidance on possible bushfire levels, BASIX and energy reports, and soil and contour surveys, and we know what councils are looking for. We will help you work out the right approval path for your block, so you are not guessing, and so nothing holds up your build.
If you are not sure what your council will need, get in touch and we will help you map it out.
