What Are The Requirements For Carports Construction?

Brisbane Council Carport Regulation

Carports are fancy and a popular choice for providing shade and off-street covered parking. Although functional, state regulations in Queensland provide certain requirements that individuals must meet before constructing a carport. Licensed builders can custom build your carport according to Queensland Government Building regulations. Their team will work with local council officials to get your project approved. 

Carport By Definition

Carports are class 10a building structures and fall under the Building Code of Australia (BCA). As a result, you need to obtain approval depending on the zone your property is located. According to the Queensland Building Act 1975, you need to seek construction approval under the following conditions:

  • An overall building height of more than 2.4m
  • A building plan area of more than 10m²
  • Any building side longer than 5m
  • A mean building height of more than 2.1m
  • Not freestanding building (attached to another building or structure)

Preferred Locations

A carport is an accepted development that is subject to the requirement of the property locations in the zones below.

  • Rural residential zone
  • Township zone
  • Rural zone
  • Environmental management zone
  • Emerging community zone

For each zone, the design must comply with identified requirements of the dwelling house code. For example, if you have a small lot, the carport must comply with the identified requirements of the dwelling house or small lot code.

Approval Guidelines

Guidelines in Building A Carport

Before commencing your plan, you must seek approval from the city council. If you don’t plan a DIY carport project, most local builders will include building approval in their packages. The reason is that they have a higher chance of obtaining building approval faster and easier. It takes about 20 days to approve an application to build a carport. However, to hasten the process, prepare the following:

Application fees

The local council publishes the latest rates on their sites. After checking the rate, pay the application processing fee and proceed with your application.


A 1:200 dimensioned Site Plan that shows the existing building structures around the carport, boundaries, and north point. A 1:100 dimensioned Floor Plan that reflects the building layout A 1:100 dimensioned Elevation that shows the height of the proposed structure from the ground

Supporting Documents

Building designs, Reports, and Form 15 Design Certificates, and Structural Engineering Drawings. Provide Energy Efficiency Assessment with the application for new buildings or in case of a major alteration to the existing building. A Portable Long Service Levy Payment for buildings valued at $150,000 or more. If you want to do it yourself, you must provide evidence of an Owner Builder Permit, especially if the building work value is over $11,000. If the value of the work exceeds $3,300, provide a copy of the Confirmation of Insurance letter from the Queensland Building Construction Commission (QBCC). This is to show that you have paid insurance.

Create a Building Plan

After obtaining approval from the city plan, lay out the plan of how you want to construct the carport. Since you can’t make any changes after completing the construction, you must plan and consider various requirements before proceeding with the construction. For example;

Roof Water Disposal

Carports are designed to provide shade and protect cars from harsh weather conditions. However, most people don’t consider the elevations while building. As a result, rainwater fills the carports after a downpour. You must plan how you want to dispose of roof water before building the carport. For example, you can install a gutter or storm water pipes as you see fit.

Adjoining Properties

Before approval, the city council will consider the carport’s surroundings. However, you should consult your neighbors to know how the new carport will affect their existing building. This way, you will avoid disputes at the end of the day. If there is any dispute before building the carport, you can contact the city council.

Fire Protection

The Building Code of Australia (BCA) lays out our plans for every class 10 buildings like carports. The fire protection requirement of the BCA aims to protect the neighborhood and surrounding buildings in case of a fire outbreak in and near the carport. Therefore, your carport must:

  • Have clearance of at least 900mm between the carport and the boundary
  • Have clearance of at least 900mm between the carport and the house
  • Have a 60/60 fire-rated wall between the house and the boundary.

Carport Design

Carport Design Rules

For an open carport with two open sides, you don’t need to meet any of the fire protection requirements. However, a class 10a open carport must have two open sides where 1/3 of its perimeter is open as well. The carport must not be closer than 1.5 meters to any room or window of an adjacent building. If you plan to use a rainwater gutter for water removal, it should be set back at least 150mm to prevent it from covering any footpath area. The council recommends that you use the same color and style of material you used for the main building for the carport. The city council will assess the soil condition, land, and design of the designated area before approval. Apart from this, the council will also consult with your neighbors.

Carport Height, Width, Length, and Support


The main front of the carport that faces the road must not be higher than 3.0 meters from the natural ground. Likewise, the rear side should not be higher than 3.5 meters.


A carport with eaves must not exceed 7.2 meters in width from one pier to the other. The width also includes two 600mm overhangs. A carport without eaves must not exceed 6 meters for a double carport. The width measures from one pier to the other.


The carport must not exceed 9 meters along any of its sides.


The front supports should not be less than 350mm2 masonry columns in case of unplanned and expected weight like hail storms on the carport.


Carports are definitely a fancy addition to residential and commercial areas. However, the design must meet Australian Standards. The assessment manager will ensure it does.
