Do You Need a Building Permit in Victoria?
Many renovations and additions in Victoria require a building permit, but the answer depends on the exact work, the building, its location and the exemptions in the Building Regulations. A project that sounds minor in conversation can still affect structure, fire safety, weatherproofing, access or public safety.
This article explains the distinction between planning and building permits, the kinds of work that commonly trigger a building permit, and who should confirm the requirements before work begins. It is general guidance, not a substitute for advice from a registered building surveyor or the relevant authority.
Building permits and planning permits do different jobs
A building permit considers whether proposed building work complies with the Building Act, Building Regulations and National Construction Code. It is concerned with matters such as structure, fire safety, health, amenity and required inspections.
A planning permit considers whether a proposed use or development is acceptable under the relevant planning scheme. Zoning, overlays, neighbourhood character, heritage, vegetation and siting can all affect that assessment.
Some projects need both permits. Others need one but not the other. If a planning permit is required, it will generally need to be obtained before the building permit can be issued.
Work that commonly requires a building permit
Examples commonly include:
• New homes, extensions and many external alterations
• Decks, verandahs, balconies and carports
• Structural alterations, including changes to loadbearing walls, beams, columns, footings or stumps
• Restumping and underpinning
• Many retaining walls
• Swimming pools and spas capable of holding more than 300 millimetres of water
• Larger sheds and outbuildings
• Some re-roofing, demolition and changes of building use
This is not a complete list. The dimensions, materials, location, building class and surrounding conditions can change the answer.
Work that may be exempt
Some limited work may be exempt from a building permit, depending on the precise conditions in the Building Regulations. Examples can include:
• Non-structural kitchen or bathroom refurbishment
• Like-for-like replacement of some windows or doors where openings and structural support are unchanged
• Certain small freestanding sheds
• Some fences and low retaining walls
• Minor repair and maintenance work
An exemption from a building permit does not remove every other obligation. Planning controls, heritage requirements, owners corporation rules, easements, plumbing requirements and other laws may still apply.
Check before design or construction begins
Do not rely on a general online list as the final answer for a particular property. A registered building surveyor can confirm whether the proposed work needs a building permit and what documentation will be required. Your council can advise about planning controls and municipal building matters.
The Victorian regulator’s current practice note explains how the permit requirement and exemptions operate:

Why does a deck need a permit?
A deck can feel like a simple addition, but it must safely support people, resist movement, drain properly and connect to the existing building without creating structural or moisture problems. Falls from height, balustrade failures and collapsed structures can cause serious injury.
That is why structural work is assessed and inspected rather than left to assumption. The permit process is not proof that nothing can ever go wrong, but it establishes minimum requirements, nominated inspections and a documented path to approval.
What happens when a building permit is required?
A building permit is issued by a registered building surveyor. The surveyor is not the designer and does not prepare the project documentation for you. They assess the submitted documents, nominate mandatory inspections and determine whether the proposed work complies with the applicable requirements.
Depending on the project, an application may require:
• Architectural drawings and specifications
• Structural engineering drawings and computations
• An energy assessment
• A geotechnical or soil report
• A certificate of title and relevant property information
• Evidence of a planning permit, where one is required
• Reports or consents from council or other authorities
The exact list depends on the work. Confirm it early because consultant input, authority approvals and changes to the design can affect both programme and budget.
Start with the property and the proposed work
Permit requirements are only one part of deciding whether a renovation is feasible. Planning controls, site constraints, existing conditions, project scope and total budget should be considered together.
Our Home Masterplan Report investigates those questions before you commit to a design direction:
Where to get advice
For building-permit requirements, speak with a registered building surveyor or consult the Victorian Building and Plumbing Commission’s guidance. For planning requirements, contact the planning department at the relevant council or seek advice from an architect or town planner.

A quiet word about unapproved work
In my experience, permit problems often become visible when a property is sold, refinanced or renovated again. Purchasers and their advisers may obtain council records showing permits, certificates, notices or orders affecting the property. Missing approvals can lead to further investigation, retrospective documentation, opening up completed work, rectification or removal.
That does not mean every undocumented alteration is automatically unsafe. It does mean the owner may need to prove what was built and whether it complies, often long after the easiest opportunity to document and inspect it has passed.
Whisker Architecture only works on projects through compliant approval pathways. If you are considering buying a property with questionable alterations, obtain advice from the appropriate building, planning, legal and insurance professionals before relying on the work.
