.

Anyone can apply for a building permit including the owner, builder, architect or building surveyor. The applicant provides details of the person responsible for the work, i.e. the builder, in the application form. The builder takes responsibility for ensuring the construction complies with the applicable building standards and the requirements of the building permit.

The building commission website contains a lot of helpful information regarding building work, several are listed below:

There are two types of building permit applications 'certified' and 'uncertified' which are explained below:

.

Certified Building Permit Application (Form BA1)

A certified application is provided by a private non-local government building surveying contractor & must be accompanied by a Certificate of Design Compliance. This type of application can be for any class of building and incidental structure and the shire, as the permit authority has 10 business days to determine the application.

Applications for Class 1b and Class 2 to Class 9 buildings (commercial) must be made as certified applications whereas this is optional for Class 1a and 10 buildings and incidental structures.

Note: Certification from a structural engineer is not to be confused with building certification, they are two separate disciplines.

.

Uncertified Building permit Applications (Form BA2)

An uncertified application is submitted to the permit authority without a certificate of design compliance and can only be made for Class 1a and Class 10 buildings. The building surveyor employed by the permit authority (the Shire) checks the proposal and issues a certificate of design compliance and the building permit. The permit authority has 25 business days to determine an uncertified application.
