Do you need a garage building permit in Melbourne?

Planning a new garage in Melbourne? Before you start thinking about layouts, materials or driveway access, there’s one important question to answer first: do you actually need a permit to build it?

The answer is yes, you do need one. But that doesn’t mean the process needs to be overwhelming. Permit requirements can vary depending on the size of the garage, where it’s positioned on your property, and the overlays or council regulations affecting your block.

This guide explains when a garage building permit is required in Melbourne, the difference between planning and building permits, and what to expect throughout the approval process. You can also explore how a garage building permit fits into the wider build process with Custom Outdoor Living.

Key takeaways

All Melbourne homeowners need a building permit to construct a garage, and many also need a planning permit from council.
A building permit covers safety and construction compliance, while a planning permit deals with land use and overlays.
Building without the right permits can lead to fines, demolition orders and issues when selling your property.

The short answer: When you need a permit for a garage in Melbourne

Yes, you do need a permit to build a garage. Every garage requires a building permit, and the exact requirements depend on factors like size, height, materials, location on the block and any planning overlays. Even small changes can affect what approval is needed. If you’re unsure, reviewing your project early helps avoid delays. You can start by understanding the role of a garage building permit and how it applies to your build.

Building permit vs planning permit: What’s the difference

These two permits are often confused, but they serve different purposes.

A building permit is issued by a registered building surveyor. It confirms that your garage design meets structural and safety requirements under the Victorian Building Regulations 2025. It also allows construction to begin and ensures inspections take place at key stages.

A planning permit, on the other hand, is issued by your local council. It looks at how the garage fits within your property and neighbourhood. This includes zoning, overlays, setbacks and overall impact on the streetscape.

In many Melbourne suburbs, you will need both.

When a permit is required: The key triggers

Several common triggers determine whether permits for building a garage are required. All garages require a building permit, regardless of size. Floor area mainly affects planning: most garages exceed the 10 square metre threshold set out in the Victorian Building Regulations 2025. Height is another consideration, especially if the structure is close to boundaries.

Materials can also affect approval. Masonry construction often brings additional requirements. The position of the garage on the block, particularly near boundaries or easements, is another key trigger. Planning overlays, such as heritage or vegetation controls, can also require council approval.

Technically, every garage requires a building permit, regardless of size. In practice, very small, non-habitable structures like sheds are often overlooked, but a functional garage will always need one.

Even a small structure will still trigger a planning permit, depending on overlays and zoning. This is why it’s important to check both pathways before starting.

The garage building permit process, step by step

The permit process is straightforward when managed properly. Here’s how it typically works:

Initial site review: Your builder or designer reviews your block, measurements and any council overlays.
Concept and drawings: Plans are prepared to show the size, position and design of the garage.
Planning permit: An application is submitted to council. This stage considers zoning, setbacks and neighbourhood character.
Building permit application: A registered building surveyor assesses the plans for compliance with regulations.
Approval and construction: Once approved, construction can begin with inspections at key stages.
Final sign-off: After completion, the surveyor issues a certificate confirming the garage meets all requirements.

An experienced builder will manage this entire process on your behalf.

Cost, timelines and what happens without a permit

Permit costs in Melbourne vary depending on the size and complexity of the garage. A building permit typically ranges from $1500 to $2,500. Planning permits can add another $1500 to $2,500 or more, depending on council requirements and whether reports are needed with some permit costs falling between the $5,000 to $6,000 range.

Approval timelines also vary. A building permit can take a few weeks once plans are finalised. Planning permits may take several weeks or longer, especially if advertising or objections are involved.

Building without the correct permits carries real risks. Councils can issue fines or require the structure to be modified or removed. It can also create complications when selling your property, as unapproved structures often need retrospective approval.
