It's one of the most common questions homeowners ask: "Do I need a permit for a garage?" The answer, like most things in Victorian planning, is "it depends." And that ambiguity is exactly what creates opportunity for builders who understand the rules.
The Permit Landscape
Building permit: almost always needed. Under the Building Regulations 2018, a detached structure is exempt only if it's under 10m² floor area, under 3m high (or under 2.4m if within 1m of a boundary), and not attached to an existing building. Any real garage or carport will exceed 10m², so in practice you'll need a building permit.
Planning permit: needed in specific situations:
- The garage or carport is in front of the dwelling (within the front setback). This is the most common trigger.
- The property is in a Heritage Overlay, where councils care a lot about what your garage looks like from the street.
- The structure doesn't comply with ResCode standards for site coverage or setbacks.
- The building exceeds height limits for the zone.
Carports in the front setback are a particularly common DA, because many Melbourne homes have old single carports that owners want to replace with double garages, but the only available space is in front of the house where it's visible from the street and affects the neighbourhood character that councils are increasingly protective of. That needs planning approval.
Why Garage DAs Are Worth Watching
Garage and carport projects might seem small compared to renovations or new homes, but they have some qualities that make them attractive work:
Quick turnaround. A standard double garage can be built in a few weeks. You can fit more garage jobs into your calendar than you can renovation projects.
Straightforward scope. Less design complexity means less back-and-forth with the client. The plans are simpler, the build is faster, and there's less that can go wrong.
Follow-on opportunities. A garage DA often comes with related work: driveway resurfacing, concreting, fencing, electrical (automatic doors, lighting, power points), even plumbing if the garage includes a laundry or bathroom.
Higher-end work in heritage areas. A "double garage in Heritage Overlay" DA in Hawthorn or Kew isn't a $15,000 Colorbond job. It might be a $40,000+ brick garage with specific architectural detailing to match the heritage house. The permit conditions often dictate materials and finishes, which pushes the budget up.
What These DAs Look Like
Typical garage and carport descriptions in our system:
- "Construction of a double garage": straightforward, likely in or near the front setback
- "Carport in front setback": needs planning approval because it's in front of the house
- "Garage with studio above": more common in inner suburbs where space is tight. This is a bigger project.
- "Replacement of existing single garage with new double garage": demo and rebuild. Often includes new driveway.
- "Carport and associated driveway crossover": includes council works (the crossover) which adds complexity but also adds to the project value
Who Does This Work?
Garage construction crosses several trades:
- General builders for brick, timber or rendered garages
- Steel fabricators for Colorbond and steel-frame structures (a big share of the market)
- Concrete specialists for slabs and driveways
- Electricians for automatic doors, lighting, power points, sub-boards
- Plumbers if the garage includes a laundry or bathroom (surprisingly common in dual-occupancy situations)
If you're any of these trades, garage DAs are relevant to you. The steel fabricators and general builders get the primary contract, but the electrical and plumbing work is often quoted separately.
Tips for Winning Garage Work
-
Quote the complete package. Slab, structure, electrical, automatic door opener, driveway. Homeowners prefer dealing with one person.
-
Know your front setback rules. If the DA is for a structure in the front setback, you should understand the planning conditions. Being able to explain them to the client positions you as an expert.
-
Show material options. Colorbond vs brick vs rendered block vs timber. Show the homeowner options with rough cost comparisons. The DA plans might specify one material, but conditions sometimes allow alternatives.
-
Check for follow-on work. New garage = new driveway? New fencing? Landscaping around the garage? Ask the question.
