Building Permits for Melbourne Renovations: A Homeowner's Guide
If you are renovating or extending a home in Melbourne, the safest starting assumption is that you need a building permit. In Victoria, building work needs one unless it is specifically exempt under the Building Regulations, and the permit must be in hand before any construction begins. Many projects also need a planning permit from your local council first, particularly in heritage areas.
This guide explains how the two permits differ, which work usually needs approval, what the process looks like, and where Melbourne renovations tend to get stuck. We have guided plenty of homeowners through this, and the same worries come up again and again. So we have answered them in plain words.
TL;DR
Most renovations that change structure, add floor area, open up walls or alter the roof need a building permit in Victoria. Only specific, minor work is exempt.
A building permit is about safety and compliance. A planning permit is about how land is used and developed. A single project can need both, and the planning permit comes first.
A registered private building surveyor (or occasionally a council surveyor) issues the building permit. You, as the owner, remain responsible for making sure the permits are in place.
Heritage overlays add planning requirements for demolition, external changes, fences and even some repainting.
Check your property on VicPlan and talk to a builder or surveyor before you finalise design. Early checks prevent months of delay.

Do you need a building permit for your renovation?
The rule in Victoria is simple to state and easy to underestimate. The Victorian Building Authority (VBA) says all building work requires a permit unless the Building Regulations 2018 exempt it. Building work is defined broadly. It covers construction, demolition, removal, repair, alteration, enlargement and extension of a building, as well as placing or relocating a building on land.
So the question is not “is my project big enough?” It is “is my project on the exemption list?” For most homeowners planning a genuine renovation, the answer is no.
A useful way to think about it is to ask four questions about your plans:
Will it change the structure (walls, beams, footings, roof framing)?
Will it add floor area or height?
Will it alter how the building protects people, such as fire separation, egress or smoke alarms?
Does it involve demolition or removal of part of the building?
A yes to any of these points strongly towards a permit. For a deeper look at how structural work is approached, our guide to structural renovation costs, repairs and permits in Melbourne is a good companion read.
Work that almost always needs a building permit
These are the projects we see most often, and they should all be treated as permit work:
Home extensions, single or double storey, including rear additions and second-storey additions.
Removing or altering load-bearing walls, such as opening up a kitchen and living area.
Loft and attic conversions, which change usable floor area, stairs, headroom and often fire safety.
Knockdown rebuilds and new homes, where there is no size at which the permit stops applying.
Decks, verandahs and carports that are attached to the house or beyond exempt limits.
Underpinning, restumping or major structural repairs.
Demolition, including partial demolition. We cover this separately in do you need a demolition permit in Melbourne.
Swimming pools and spas, which have their own barrier and safety rules.
If your plans sit in this list, you are looking at our daily work. Our home extensions and home renovations services both include managing permits and approvals as part of the build.
Work that may be exempt
The VBA’s guidance recognises that some work does not need a permit. Typical examples include minor repairs, renewals or maintenance that do not affect structural soundness, essential safety measures, or the floor area or height of the building. Small freestanding structures such as certain pergolas and sheds can also be exempt, but only within size and siting limits set out in the Regulations.
In practice, cosmetic work is where exemption is most likely:
Repainting internal walls
Replacing floor coverings
Swapping a kitchen benchtop or cabinetry in the same position
Replacing taps, a vanity or a shower screen like for like
Two cautions. First, exemptions come with conditions. A small shed or pergola may be fine in the backyard but not if it sits too close to a boundary or is in an area with special overlays. Second, “cosmetic” jobs can turn structural once the walls are open. If you find rotten framing or want to move a wall, the answer changes.
Plumbing and electrical work are a separate matter again. They are generally done by licensed tradespeople and certified under their own rules, whether or not the wider job needs a building permit. Ask your builder or plumber to confirm what applies to your job.
Building permit vs planning permit
This is where many Melbourne homeowners get tangled, so it is worth slowing down.
Planning permit | Building permit | |
What it answers | Can the land be developed or used this way? | Does the proposed work comply with building regulations? |
Who decides | Your local council | A registered building surveyor |
Focus | Neighbourhood character, heritage, overlays, setbacks, overlooking | Structure, fire safety, energy efficiency, health and safety |
Order | First, if required | After planning approval |
A building permit certifies that the plans meet the building regulations. A planning permit allows the land to be developed or used in a particular way. A renovation might need both, and the planning permit is issued first.
The City of Melbourne notes that a planning permit is generally required for additions to residential properties and when there is demolition, especially within a heritage overlay. Other councils have their own thresholds, which depend on your zone and overlays.
We have written full guides to each stage if you want detail: planning permits in Melbourne and building permits in Melbourne.
Check your overlays before you design
The single most valuable half hour you can spend is on VicPlan, the state’s planning map. Type in your address and see which zone and overlays apply. A heritage overlay, a neighbourhood character overlay or a flooding overlay can change what is allowed and how long approval takes. Our article on planning overlays and VicPlan checks shows how a quick check up front avoids a long permit delay later.
Heritage homes and special overlays
Melbourne has streets of Victorian terraces, Edwardian villas and interwar bungalows, and many of them sit under a heritage overlay. These homes have witnessed generations, and the rules aim to keep what makes the street worth walking down.
According to the City of Melbourne’s heritage owner’s guide, a planning permit is needed in a heritage overlay to demolish or remove a building, to construct a fence, or to externally paint an unpainted surface or repaint in a different colour. External alterations can also trigger a permit.
That catches people out. Homeowners expect a permit for a new rear addition, but not for a fence or a colour change. Then the work starts and a neighbour or council officer asks to see the paperwork.
A few practical points for heritage projects:
Ask your council about pre-application advice. Heritage advisers can tell you early what is likely to be supported.
Keep the original street-facing fabric in mind. Additions that sit behind or are set back from the original roofline often fare better.
Document the existing condition with photos and measurements before design starts.
Expect more time. Heritage referrals can add weeks.
We have a dedicated heritage renovation checklist and a step-by-step guide to renovating heritage homes. If you own a period home, our heritage home renovations and restorations service is built around exactly these constraints.
Who issues the permit, and how the process works
In Victoria, building permits are issued by a registered building surveyor. Most homeowners engage a private building surveyor. The VBA explains that permits exist for consumer protection: the practitioners must be registered and insured, and the work is independently assessed and inspected.
Here is the usual sequence for a renovation that needs both permits.
Feasibility and site check. Confirm zoning, overlays, easements, boundaries and any restrictive covenants on title. This is the stage where we often save clients the most money, because problems found now cost far less than problems found after drawings.
Design and drawings. An architect or building designer prepares plans that respond to your brief and to planning rules. Our architectural house designs service is published from $15,000 to $35,000 as a one-off, depending on scope.
Planning permit, if required. Lodged with your council. Councils may ask for more information, and neighbours may be notified. Our six steps for the town planning process covers how to keep this stage moving.
Engineering and energy reports. Structural computations, soil reports and energy ratings are typically needed for the building permit application.
Building permit application. Your surveyor checks the documents against the Building Regulations, may request amendments, then issues the permit.
Construction and inspections. The surveyor inspects at mandatory stages, such as footings, frame and final.
Occupancy or final certificate. Once the surveyor is satisfied, the project is certified as complete.
If a surveyor refuses a permit, you do not have to give up. You can amend the application to meet the requirements, or appeal the decision to the Building Appeals Board.
You are responsible, even if your builder lodges the application
This point surprises people. Consumer Affairs Victoria’s plans and permits checklist makes clear that the homeowner is responsible for ensuring both planning and building permits are obtained, even when a builder or architect handles the application on their behalf.
What does that mean day to day?
Ask to see the permit before work starts. Do not rely on a verbal assurance.
Check that the permit matches the scope you are paying for.
Keep copies of the permit, approved plans and inspection certificates. You will need them when you sell or refinance.
Be wary of signing an application as an owner-builder unless you really intend to take on the full responsibility. Consumer Affairs Victoria cautions that this should only be done if you hold an Owner Builder Certificate of Consent and understand what you are taking on.
This is one reason many families choose a builder who manages the whole process. When one team is accountable for design, approvals and construction, the paperwork stays attached to the project rather than falling between people.
What does a building permit cost, and how long does it take?
We would rather be honest than give you a tidy number that does not fit your site. The cost of getting a permit is made up of several parts, and they vary with the size and complexity of the project:
The building surveyor’s fee, which they quote for your project
Council fees, including any planning application fee
Statutory levies that apply to building work
Consultant reports such as engineering, energy rating and soil testing
Drawings, which are a design cost rather than a permit cost
Get at least a written quote from your surveyor that states what is included, how many inspections are covered, and what happens if amendments are needed.
Timing depends mostly on whether planning is involved. A simple extension in a standard zone with no overlays can move through relatively quickly. A heritage property, a site with several overlays, or a design that needs advertising to neighbours takes longer. Our experience is that most delays come from incomplete information, not from the surveyor or council taking their time. Responding promptly to requests and getting reports ready early makes a real difference.
One more cost rule is worth knowing. Under Victorian rules, when the final project cost increases by a set threshold, owners or applicants must notify the building permit’s surveyor. Consumer Affairs Victoria explains this in its guidance on managing building project costs. Ask your builder how variations will be priced and documented from day one.
Permits also have time limits. They expect work to start within a set period and finish within another. If a permit lapses and work continues, the work becomes illegal and the surveyor can issue a building order to stop construction. Your permit will state the dates that apply to your job, so diarise them.
Not sure what your project needs?
If you have a plan in your head but no idea which approvals it triggers, that is the ideal time to talk to us. We offer a free project feasibility call where we look at your address, your goals and your likely approval pathway before you commit to drawings. Whether you are weighing an extension, a major renovation, a loft conversion or a knockdown rebuild, we will tell you what to expect.
You can book a free project feasibility call or look at our design and build approach, where design, permits, approvals and construction sit under one roof.
What happens if you renovate without a permit?
It can be tempting to skip the process, especially for a job that feels small. The risks are real:
Stop orders and fines. A surveyor or council can issue an order to stop work, and penalties may apply.
Rectification. You may be required to open up finished work for inspection or to bring it up to standard, at your cost.
Insurance problems. Insurers can query claims connected to unapproved work.
Trouble at sale. Buyers’ solicitors ask for permits and certificates. Missing paperwork can delay or derail a contract.
Safety. The permit process exists because structural, fire and electrical shortcuts hurt people.
If you have already bought a home with unpermitted work, speak to a registered building surveyor. They can advise whether the work can be assessed and documented retrospectively.
How we handle permits on your project
We manage the building process from start to finish, including design coordination, permits and approvals, and construction oversight. In practice that means you have one point of contact who explains where the project sits, what is needed next and why. We also keep the permit in view while we build, because the approved plans are what we are building to.
Our approach comes from a simple belief. Homeowners who are building or renovating are often feeling overwhelmed, and clear communication takes a lot of that weight off. You should not need a degree in planning law to renovate your own home.
If you are in the inner south-east, our Glen Iris team is local to many of the heritage and character streets we have been describing.
FAQ
Do I need a building permit to renovate a kitchen in Melbourne?
Not always. Replacing cabinetry, benchtops and appliances in the same layout is often exempt. If you remove a wall, change the structure, alter windows or relocate plumbing in ways that need certification, the project moves into permit territory. Ask a registered building surveyor to confirm before you order materials.
Can my builder apply for the permit on my behalf?
Yes, builders and architects commonly lodge the application with your authority. The legal responsibility for making sure the planning and building permits are obtained still sits with you as the owner. Ask to see the issued permit before any work starts.
Do I need a planning permit as well as a building permit?
Possibly. A planning permit is generally needed for additions to residential properties and for demolition, especially in a heritage overlay. Check your property on VicPlan and ask your council. If a planning permit is needed, it is obtained before the building permit.
What if my building permit application is refused?
You have two options. You can change the application so it meets the requirements, or you can appeal the decision to the Building Appeals Board. A good builder or designer will help you work out which route makes sense.
Does repainting a heritage home need a permit?
It can. In a heritage overlay, a planning permit is needed to paint an unpainted external surface or to repaint it in a different colour. Internal painting is generally not affected. Confirm the details with your council before you pick colours.
