The journey through the building approvals process varies significantly depending on the class of building and the nature of the construction or renovation. This section provides a step-by-step guide through the typical sequences of approvals needed for different types of buildings, detailing the various permits and documents required along the way.

Understanding the Approval Sequences

Certified and Uncertified Applications:

• Certified Applications (BA1): These are used for any class of building where a Certificate of Design Compliance (CDC) has been obtained before the application is submitted. The process is generally quicker, with the permit authority required to make a decision within 10 business days.
• Uncertified Applications (BA2): Typically for Class 1a (houses) and Class 10 buildings (non-habitable structures like sheds and carports), where the CDC is obtained from the permit authority after the application is submitted. The decision timeframe is 25 business days.

The Path from Application to Construction:

• Building Permit Issuance: Following the approval of either certified or uncertified applications, a building permit is issued, allowing construction to commence.
• Occupancy Permit Requirements: For buildings where public access or permanent occupancy is intended, such as in Class 2 to Class 9 buildings, an occupancy permit must be obtained after construction is completed to ensure the building is safe and suitable for use.

Detailed Steps in Approval Processes

Building Permit Process (BA1 for Certified, BA2 for Uncertified):

• Submission: Applications are accompanied by the necessary CDC, plans, specifications, and evidence of compliance with relevant laws.
• Assessment: The permit authority assesses the application against the Building Code of Australia and other relevant standards.
• Decision: A permit is either granted or refused. If approved, construction can commence according to the stipulated plans.

Occupancy Permit Process (BA9):

• Completion of Construction: Once the building work is completed, a Certificate of Construction Compliance (CCC) or a Certificate of Building Compliance (CBC) is required to apply for an occupancy permit.
• Safety and Compliance Checks: The building must meet all safety and usability standards for its intended purpose.
• Issuance: Upon successful verification, the occupancy permit is issued, allowing the building to be occupied or used.

Examples of Specific Approval Sequences

For Residential and Non-Habitable Structures (Class 1a and Class 10):

• Application: Typically uncertified, with the CDC obtained post-application.
• Construction: Follows the granting of the building permit.
• Completion: No occupancy permit required unless the structure’s use changes that necessitate such a permit.

For Commercial and Public Buildings (Class 2 to Class 9):

• Application: Must be certified with all compliance documents ready at submission.
• Construction: Begins post-approval, adhering strictly to the approved plans.
• Occupancy: Requires an occupancy permit verifying the building’s safety and suitability for public use.

Conclusion: Streamlining the Approval Process

Understanding the typical approval sequences for building projects in Western Australia can greatly enhance the efficiency and compliance of any construction project. By following these established pathways, builders and developers can ensure that their projects progress smoothly from conception through to occupancy, adhering to all necessary safety standards and regulatory requirements.
