If you’re planning to build, renovate, or add a structure to your property, one of the first questions you’ll likely ask is, “How do I get a building permit?” The answer depends on where you live, what you’re building, and how much work the project involves.
In this blog, we will explain what a building permit is, when you need one, and how the requirements differ across Queensland, New South Wales, and Victoria. We will also cover the application process and common mistakes to avoid when applying for a building permit.
What Is a Building Permit?
A building permit is a formal approval that confirms your proposed building work has been assessed against the National Construction Code and relevant state or territory regulations. It is generally required before construction begins for new buildings, structural alterations, and additions. Certain other types of building works, such as pools, decks, carports, and retaining walls over a particular height, may also require approval depending on local requirements.
The term “building permit” is commonly used in everyday speech, but the formal terminology differs between states and territories. In Queensland, it is generally called a “building approval”, while in Victoria, it is called a “building permit”. In NSW, the relevant approval is generally a “Construction Certificate” after development consent, or a “Complying Development Certificate” (CDC) for eligible projects using the complying development pathway.
It is also worth noting that building approval differs from development approval or planning permission, which deal with land use, zoning, and neighbourhood impact. Depending on your project and location, you may need both.
Building Classifications Under the NCC
While categories differ between states, building permits generally fall into a few types, including:
- Class 1: Houses (detached dwellings, townhouses, terrace houses)
- Class 2: Apartment buildings (multi-residential)
- Class 3: Residential buildings, such as hotels, motels, and boarding houses
- Class 4: A dwelling within a non-residential building
- Class 5 to 9: Commercial, industrial, and public buildings (offices, retail, warehouses, factories, hospitals, schools)
- Class 10: Non-habitable structures, such as sheds, carports, garages, fences, retaining walls, and pools
When Is a Building Permit Required?
Queensland
In Queensland, a building permit or building approval is required for most building work, including new homes, extensions, structural changes, pools, and many outbuildings. Some minor structures may be exempt depending on size, height, and location, but it’s always worth checking before starting work.
For a more detailed breakdown of when a building permit is required in Queensland, see our dedicated blog on Queensland building approval requirements.
New South Wales
In NSW, building work generally requires either a Construction Certificate (issued after development consent) or a Complying Development Certificate. A Construction Certificate signifies approval for construction only, while a Complying Development Certificate combines planning and building approvals for eligible projects into a single streamlined pathway.
Victoria
Victoria requires a building permit for most building work, issued either by a municipal building surveyor or a private registered building surveyor.
This includes new builds, renovations, pools, and many smaller structures. Some minor works may be exempt, but exemptions are specific and should not be assumed without checking.
How Do You Get a Building Permit?
The process for getting a building permit is similar across Australia, but the requirements vary by state and project type. Some projects may also require separate planning or development approval before building work can begin.
Process From Application to Approval in Queensland
- Engage a building certifier: In Queensland, you can use a private certifier or your local council’s building certification team.
- Submit your application: This includes architectural plans, structural engineering details (where required), site plans, and supporting documentation, such as soil reports or energy-efficiency statements.
- Assessment against the Queensland Development Code and National Construction Code: The certifier checks compliance with structural, fire safety, access, and amenity requirements.
- Request for information: If anything is missing or unclear, the certifier will request additional details before proceeding.
- Permit issued: Once compliant, the certifier issues the building approval, and work can commence, along with any required inspections during construction.
Process From Application to Approval in New South Wales
- Determine your pathway: Decide whether your project suits a Complying Development Certificate (CDC) or requires a development application followed by a Construction Certificate (CC).
- Lodge your application: Submit your application to the council or an accredited certifier, along with plans, specifications, and any required reports.
- Assessment: The application is assessed against the Building Code of Australia, council planning controls and any relevant state environmental planning policies.
- Certificate issued: For a CDC, this single certificate provides planning and construction approval. For the development application pathway, construction can begin once the CC is issued. Both pathways are subject to mandatory inspections at key stages.
- Occupation Certificate: Once construction is complete, an Occupation Certificate is generally required before the building can be occupied, confirming it is suitable for occupation.
Process From Application to Approval in Victoria
- Appoint a building surveyor: Choose your local council’s building surveyor or a private registered building surveyor.
- Submit documentation: Provide plans, specifications, and any required reports, such as engineering or bushfire assessments.
- Assessment: The building surveyor assesses the application against the Building Code of Australia and Victorian regulations.
- Permit issued: Once approved, the building permit is issued, outlining the required inspection stages.
- Occupancy permit or certificate of final inspection: Once construction is complete, the relevant document is issued after the surveyor confirms the work meets the applicable requirements.

Common Mistakes To Avoid
When applying for a building permit, there are a few common mistakes to avoid, including:
- Assuming small projects don’t need approval: Decks, sheds, retaining walls, and pools often require permits depending on size and height, even if they seem minor.
- Using outdated plans or incomplete documentation: This leads to delays, as certifiers may need to request missing information.
- Confusing planning approval with building approval: These are separate processes in most states, and both may be required.
- Not booking required inspections: Skipping mandatory inspection stages can delay your occupancy certificate at the end of the project.
Final Thoughts
To answer the question: How do I get a building permit? Begin with understanding your state’s requirements, engaging the right certifier early, and preparing the required documentation. While the process varies between Queensland, New South Wales, and Victoria, obtaining the necessary approvals helps ensure your project meets building regulations and can proceed without avoidable delays.
