Carport, Garage or Shed

The following is the minimum information that is required to be submitted for a building permit application.

Whilst the information required might seem excessive, please note that it is the Relevant Building Surveyors (RBS) responsibility to ensure that the application contains sufficient information to determine compliance with the Building Act and Regulations. It is not appropriate for the RBS to “mark-up” plans or accept notes on plans that are too general.

Where the RBS is not satisfied that the appropriate information has been provided they must not issue the building permit and should request further information.

Have you checked with the relevant officers if you require a Planning Approval? (Note: where a planning approval is required, a building permit cannot be issued until the Planning Approval has been received).

Is the structure closer than 6m from the existing building? If so, has the designer of the building confirmed your properties Bushfire Attack Level (BAL), which is now required for every site? (Please see information provided by the Building Commission “A guide to assessing your property’s Bushfire Attack Level”).
