Building Permits for Melbourne Home Renovations

One of the most common questions Melbourne homeowners ask before starting a renovation is whether they need a permit. The answer depends on what you're doing — and getting it wrong can be extremely costly. Unpermitted work can result in fines, orders to demolish work at your own expense, and major problems when you try to sell.

This guide explains exactly when you need a building permit, when you also need a planning permit, what the process looks like, and what happens if you skip it.

The Short Answer

When You Don't Need a Permit

Many cosmetic renovations in Melbourne don't require a building permit. This generally includes:

• Painting and decorating — internal and external
• Replacing flooring — carpet, timber, tiles (not structural)
• New kitchen cabinetry without moving plumbing — replacing cabinet doors, benchtops and appliances in the same locations
• Replacing windows — same size, same location, like-for-like replacement
• Installing new light fittings — though electrical work must still be done by a licensed electrician who provides a Certificate of Electrical Safety
• Garden landscaping — fences under 2m in most councils, garden beds, non-structural paving

If your renovation is purely cosmetic and doesn't touch the structure, plumbing layout, or electrical system beyond like-for-like replacements, you're unlikely to need a building permit. When in doubt, call a registered building surveyor for a free preliminary conversation — most will give you a quick answer at no cost.

When You Need a Building Permit

A building permit is required for most structural work. In Victoria, building permits are issued by a registered building surveyor — either through your local council or a private building surveyor. Your builder typically manages this process on your behalf.

You almost certainly need a building permit for:

• Any structural extension or new room
• Removing or altering a load-bearing wall
• Significant plumbing alterations — moving bathroom, kitchen or laundry plumbing
• Adding a deck, pergola or carport over certain size thresholds
• Underpinning or altering the foundation of the home
• Installing a swimming pool or spa
• A new garage or carport
• Adding a second storey or significant upper level alterations
• Any work valued over
  0,000 that affects the structure of the building

For bathroom renovations specifically: A full strip-out with new waterproofing does not always require a building permit if no structural changes are made. However if you're moving plumbing, removing walls, or changing the floor plan, a permit is likely required. Check with a building surveyor before starting.

When You Also Need a Planning Permit

A planning permit is separate from a building permit and is issued by your local council — not a building surveyor. You may need both.

Planning permits are most commonly required when:

• Your property is in a heritage overlay
• Your extension exceeds certain size limits under your council's planning scheme
• The renovation significantly changes the external appearance of the property
• You're subdividing land or creating a secondary dwelling (granny flat) on a lot under 300m²
• You're in a Neighbourhood Residential Zone with specific restrictions

Planning permits take significantly longer than building permits — typically 3–6 months, and sometimes longer in councils with heavy workloads or where objections are lodged by neighbours.

Heritage Overlays in Melbourne's Northern Suburbs

Heritage overlays are planning controls that apply to properties or areas of cultural or historical significance. They affect what you can build, what materials you can use, and how visible changes can be from the street.

Suburbs with significant heritage overlays in Melbourne's north include:

• Fitzroy North — large portions of the suburb are heritage-listed
• Northcote — heritage overlays covering many period streetscapes
• Brunswick — particularly around federation and Victorian-era housing
• Essendon — parts of the suburb have heritage significance
• Moonee Ponds — Edwardian and Art Deco precincts

What a heritage overlay means for your renovation:

• A planning permit is almost always required for external changes
• New extensions must typically be set back from the street and be visually recessive
• Materials must often match or complement the existing heritage character
• Approval can take 3–6 months and may involve a heritage architect

How to check: Search your property on the Victorian Government's Planning Maps Online at mapshare.vic.gov.au. You can see all planning zones and overlays that apply to your specific address.

Who Applies for the Permits?

Building permit: Your builder or registered building practitioner typically applies for this on your behalf through a registered building surveyor. Confirm with your builder before signing a contract — make sure it's explicitly stated in the contract who is responsible for obtaining the building permit.

Planning permit: Your builder, architect or town planner applies to your local council. This is a longer and more complex process, and for heritage overlay properties, using a heritage consultant or experienced architect is strongly recommended.

Never start work before permits are issued. Starting construction before a building permit is issued is illegal in Victoria and exposes you to significant financial risk.

What Does a Building Permit Cost in Melbourne?

Building permit costs in Victoria are calculated based on the value of the work:

These are approximate figures — costs vary between building surveyors. The building surveyor's professional fee is separate from the permit levy and is negotiable.

Planning permit fees are set by council and vary significantly — typically
