Carport Regulations in Australia
Carport regulations in Australia - it is the carport owner/property owner's responsibility to check out all local regulations and seek any council approvals that may be necessary. Rules and regulations not only differ in States and Territories but can differ considerably between one local council and another. The following should be treated as a guide only.

Carport building regulations can vary from state to state and even council to council. The information on this page is meant as a guide only and you will need to check with your local authority as to what is permissible in your area.
The below is a list of things you should check with your local authority before building a carport.
How do I find the right carport information?
It can be very challenging finding the right information for your property. The best place to start is your local council website as many have fact sheets on their websites for carports and minor domestic structures – simple search for ‘carport’ in the search box in the home page.
What is a carport?
Most of the legislation defines a carport as a structure primarily used for housing a vehicle that is open on at least two sides and one third of the carport’s total perimeter.
In the Building Code of Australia (BCA), a carport is classified as a Class 10a Building.
How many carports can you have?
In NSW, you’re allowed one carport per residential dwelling on the site. Other states appear not to have specified this criteria or it varies from local council to local council.
When are carports not allowed? -Carport Regulations in Australia
If you have a small or unusually shaped section, check the local regulations to see if a carport is allowed on your property. For example, in NSW, when the property is less than 8m wide and there is no vehicle access from a secondary road (i.e. not the primary road), a carport cannot be built.
In many states, a battleaxe section requires space to turn the car around so it can drive off the property in a forward direction, limiting where (or if) a carport can be placed.
Will the carport need a building permit?
It’s best to assume that your carport will require a permit – most states require one and it’s a good place to start.
New South Wales general carport regulations
Should the carport meet the specific development standards in the policy, it doesn’t need a permit – see this information sheet here.
If any heritage item (or proposed item), is on the site, the carport will need a permit.
In foreshore areas, the carport will need a permit

You do not need planning or construction approval for many minor renovations and low-impact works (exempt development). Council approval is not needed if your project meets specific development standards.
The standards you must comply with for most exempt development works are in the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 (the State Policy).)

Western Australia general carport regulations
Carports require a Building License and Development Approval.
What is the maximum height and floor area of the carport?
Maximum heights vary, as does the part of the structure is being measured to ascertain the ‘height’. You will need to contact your local council to find out what applies to you and keep these things in mind:
- The maximum height may change depending on how close the carport is to the boundary and neighbouring buildings.
- There may also be considerations for the average height of the building, if the carport is to be attached to an existing structure.
- Shading of other houses needs to be taken into account when deciding on the height of the building.
Floor area allowances also vary and in some states. The zoning of the property may affect how large the carport area can be so before you decide on the size of your carport, know for certain which zone you are in.
What are the limitations on placing a carport near the boundary line or with concern to easements?
The frontage setback will be subject to local Council controls which will dictate how close the building can be built to the footpath. Don’t assume you can build it where you like...check first!
What are the regulations concerning carports in bushfire prone areas?
As stated in the BCA, a Class 10a building associated with a Class 1 building (a residential home) needs to provide resistance to bushfires. Further, a class 10a must not significantly increase the risk of fire spread between buildings.
For those in bushfire prone areas, it’s advisable to read through “126.96.36.199 Class 10a buildings” for a full description.
How should you dispose of the water from the roof of a carport?
An oft-forgotten aspect of building a carport is the rainwater run-off. The states listed below appear to have requirements for carport rainwater runoff disposal.
In NSW, any water that runs off the roof of your carport must run into an existing stormwater drainage system.
At the time of writing, Victoria was revising their rainwater collection rules to be more environmentally friendly.
In Queensland, the rules appear to change from council to council. For example, Ipswich Council advises roofwater must be piped to an appropriate stormwater discharge point, while Gympie encourages the use of rainwater tanks.
South Australia appears to be more flexible on how the water will be disposed, but it must be outlined in the building approval application.
Can you connect the carport to the house?
This is difficult as the Australian Standards on the carport are calculated by a qualified engineer so to ensure Standards are met, an engineer should be 'on site' to make the necessary calculations and engineering to ensure a safe attachment. This can be very costly.
Are there any regulations on the appearance of the carport?
Last but not least – check that your local council does not have requirements as to the appearance of your carport.
