Building Services

​​​​​The Shire of Manjimup is committed to providing information and assistance to owners and builders for safe and compliant buildings that will last and have minimum impact on neighbouring properties and the environment.​

In Western Australia, building legislation is governed by the Building Act 2011 (the Act) and the Building Regulations 2012 (the Regulations). The Act and the Regulations define what is building work and stipulate where a building permit is required and the process for obtaining a building permit.

The minimum standards required for all construction in Western Australia are set out in the Building Code of Australia (BCA) and the associated Australian Standards. All building applications must demonstrate compliance with the BCA.

Building applications - certified or uncertified?

When you apply for a building permit, your application will either be certified or uncertified. Certified applications are those which have been assessed by a Building Surveyor for compliance with the Standards prior to applying. Whereas the Shire's Building Surveyor will assess uncertified applications as part of the permit process. Uncertified applications are only able to be submitted for a Class 1a or Class 10 application.

In either case, a signed certificate of design compliance (CDC) is required before approval can be given. A CDC confirms that a building’s design complies with the applicable building standards.

Once submitted, the Shire has 10 business days to determine a certified application and 25 business days to determine an uncertified application. If an application is missing information or is incomplete, the Shire can 'stop the clock' until it is satisfied that all information and details have been provided.
