There are two types of building permit applications:
- Uncertified or Certified applications - Class 1 (Residential) and Class 10 (Non-Habitable) Buildings
- Certified applications - Class 2 – 9 Buildings.
Certified building permit applications (BA1 Form)
A certified building permit application means that the plans and specifications of a proposed building have been assessed by a registered private building surveyor. The building surveyor will issue a Certificate of Design Compliance (CDC) if the proposed structure complies with applicable building standards.
You will need to submit the CDC with all the plans and information certified by your private building surveyor with your building permit application.
The BA1 form is available below under 'Related documents'.
Uncertified building permit applications (BA2 Form)
An uncertified Building Permit application means that the plans and specifications for a proposed structure have NOT been assessed by a registered private building surveyor. Instead, the drawings and documents submitted with the application will be assessed by the City’s building surveyors.
The BA2 form is available below under 'Related documents'.
To obtain a building permit, you will need to complete and submit the relevant building permit application form, together with two copies of all plans and specifications to the City’s Building Services Department. The forms are available below under 'Related documents'.
Please note that the building permit application fee plus all associated State levies must be paid at the time of lodgement of your application.
The City will be unable to process your application without payment. This will delay the approval of your building permit application. In some instances, your unpaid application might even be returned to you.
Links to all forms are provided below under 'Related documents'. Please note that the majority of these forms are published by the Building Commission. The City is unable to verify the accessibility of these forms.
Building permit assessment timeframes
- Certified building permit applications: the City has 10 business days (excluding public holidays) to assess.
- Uncertified building permit applications: the City has 25 business days (excluding public holidays) to make a determination.
The above timeframes are in accordance with the Building Act 2011.
If the City’s preliminary assessment of a certified or uncertified building permit application reveals that additional information is required, the City will send out a Further Information Request letter to the nominated builder or applicant. The builder or applicant has 21 calendar days to provide the requested information to the City.
Under the Building Act 2011, the City has the right to refuse an application if all required information is not provided within the stipulated 21-day timeframe. The City also has the right to retain the application fee.
Building permit application fees
Refer to the Fees page for all planning and building related costs. Fees payable with the building permit application are based on the contract value of the proposed works (including GST).
If there is no contract, the estimated value of the works must include all material costs, labour costs, necessary services, fees payable, overheads, etc (as stipulated in the Building Regulations 2012).
