Building Services Levy

Payable on building permits and certificates.

Payment

The amount of Building Services Levy payable will vary according to the type of application and, where applicable, the value of building works undertaken. The table below shows the application types that attract BSL and how much should be paid to the local government permit authority.

Permit authorities pay the levy to Building and Energy for certificates or permits that have been issued or granted.

More information for permit authorities on remittance to Building and Energy is provided below.

Determining value of work

When estimating the value of building work, Schedule 1 of the Building Regulations 2012 requires that the value is the sum of the value of the following relevant components (including GST)

• All goods (including manufactured goods forming part of the work)
• Labour
• Services necessary
• Fees payable
• Overheads to be met
• Profit margin

More information can be found in Industry Bulletin 76 – Estimating the value of building work. The value of unauthorised work is the current value of the work as determined by the permit authority.

For local governments

Levy remittance

The Building Services (Complaint Resolution and Administration) Regulations 2011 requires a permit authority to remit the building services levy to the Building Commissioner within 14 days after the end of the month in which it issues or grants a permit or building approval certificate.

• Permit authorities are required to use Form 81 – Remittance advice and to provide a supporting report which provides a breakdown of the remittance.

Further information on the Building Services Levy:

• Industry Bulletin 143 - Building Services Levy – Changes to information requirements

Refund of the Building Services Levy

Under Regulation 16 of the Building Services (Complaint Resolution and Administration) Regulations 2011, if a permit authority refuses to grant a permit or building approval certificate, or if an applicant withdraws an application before the permit or certificate is issued or granted, the permit authority must refund the building services levy.

Once a permit or certificate is granted or issued the permit authority forwards the building services levy to Building and Energy. The levy cannot then be refunded unless the Building Commissioner assesses that there are exceptional circumstances which might qualify for a refund.

• Form 82 – Request for refund should be used when a permit or certificate was issued or granted, but there are exceptional circumstances which might qualify for a refund of the levy.Building Act fees

Building classes

The Building Code of Australia (BCA) is a national code, produced and maintained by the Australian Building Codes Board (ABCB). The BCA is Volume One and Volume Two of the National Construction Code (NCC).

The NCC provides a uniform set of technical provisions for the design and construction of buildings and other structures throughout Australia. Buildings classifications are determined in accordance with the Governing Requirements of the NCC.

Each part of a building must be classified and comply with all appropriate requirements for its classification.

The NCC groups buildings and structures by the purpose for which they are designed, constructed or adapted to be used,  rather than by the function or use they are put to, assigning each type of building or structure with a classification.  A building may have parts that have been designed, constructed or adapted for difference purposes.  In most cases, each of these parts is a separate classification.  A building (or part of a building) may also have more than one such purpose and may be assigned more than one classification.

Below is a list of the different building classifications, from Class 1 to Class 10, and an explanation of each class.

Further information including limitations and exemptions and updates on building classification is available under Part A6 of the Governing Requirements in the NCC. The NCC and other useful resources regarding building classification is available to view for free on the ABCB website.
