Information on building applications

When you apply for a building permit, you must consider whether to lodge a certified application or an uncertified application.

Certified

A certified application is where you engage a private building surveyor to complete a Certificate of Design Compliance before the application for a building permit can be submitted to the City. Building Permits for works to buildings of Class 2 to Class 9 (including alterations and additions) must be lodged as Certified Applications. Class 2 to Class 9 buildings include but are not limited to; shops, apartments, warehouses, offices, factories.

Important information: The City’s Building Services Section also provides a service for the issue of Certificate of Design Compliance. Contact Building Services for further information about this service.

Uncertified

An uncertified application is submitted directly to the City for assessment and issue of a building permit. Only buildings of Class 1 (houses) and Class 10 (eg. sheds, patios, retaining walls, pools)  can be lodged as "uncertified".

More information is available from the Government of WA Building and Energy website

The Residential Design Codes (R-Codes) provide the basis for the control of residential development throughout Western Australia. The R-Codes set out two paths to compliance:

  1. Demonstrating compliance with the Deemed To Comply criteria; or,
  2. Demonstrating compliance with the Design Principles criteria

If you are unable to comply with the Deemed to Comply criteria you may apply for a variation to the R-Codes using the application form below:

The application fee for a Codes application is based on the estimated cost of development and uses the Development Application fee schedule to calculate the fee payable:

For works up to $50,000 the fee is $147.00
For works between $50,001  - $500,000 the fee is 0.32% of the estimated cost of the development
For works between $500,000  - $2.5 million the fee is $1,700.00 + 0.257% for every $1.00 in excess of $500,000
