Standard Garage Dimensions in Victoria at a Glance
In Victoria, the standard single garage size is 3.5m wide × 6m deep (minimum) and the standard double garage size is 5.5m wide × 6m deep (minimum), as set by ResCode (Clause 52.06) and Australian Standard AS 2890.1. A 3-car garage requires at least 8.5m wide × 6m deep, and a 4-car garage requires 11m wide × 6m deep. These minimums apply across all residential zones in Victoria — including the General Residential Zone (GRZ) and Neighbourhood Residential Zone (NRZ) — and must be measured as internal dimensions inside the garage or carport structure.
The table below summarises minimum and recommended dimensions for each garage type — whether you are building a single garage for a new home, a double garage for a dual occupancy, or a larger multi-car facility for a townhouse development.
| Garage Type | Minimum Width | Minimum Depth | Recommended Width | Min. Door Width | Min. Door Height |
|---|---|---|---|---|---|
| Single garage | 3.5m | 6.0m | 3.6–4.0m | 2.4m | 2.1m |
| Double garage | 5.5m | 6.0m | 6.0m | 4.8m | 2.1m |
| Triple (3-car) garage | 8.5m | 6.0m | 9.0m | 7.2m | 2.1m |
| Four-car garage | 11.0m | 6.0m | 12.0m | 9.6m | 2.1m |
Note: A door height of 2.4m is recommended for SUVs, vans, and 4WDs. Tandem parking arrangements (one car behind another) are permitted under Clause 52.06 where both spaces serve the same dwelling.
Standard Single & Double Garage Dimensions in Victoria
Victoria’s ResCode standards specify minimum garage dimensions that apply across most residential zones. Understanding these requirements is fundamental to any ResCode (Clause 52.06) compliance assessment. The Clause 52.06 car parking rules set the enforceable minimums that every Melbourne developer must meet at permit stage:
- Single garage: 3.5m wide × 6m deep (minimum). Recommended 3.6–4.0m wide for SUVs and dual-cab utes.
- Double garage (2 car): 5.5m wide × 6m deep (minimum). A 6.0m width is recommended for comfortable door opening between vehicles.
- Triple (3-car) garage: 8.5m wide × 6m deep (minimum). Typically 9.0m wide in practice to allow adequate clearance.
- Four-car garage: 11m wide × 6m deep (minimum). May require 12.0m for comfortable side-by-side access.
These dimensions provide adequate clearance for vehicle entry, manoeuvring, and door opening. Garages designed to the minimum may feel tight for larger modern vehicles — where budget and site area allow, building to the recommended dimensions avoids future access issues.
Garage dimensions also contribute to site coverage calculations in Victoria. Under ResCode, roofed structures including garages and carports count toward the maximum permissible site coverage (typically 60% in the General Residential Zone), so oversizing a garage can constrain the development envelope. See our detailed guide on ResCode Standard B28 site coverage and permeability to understand how garage footprints affect your overall development yield.
Garage size also interacts directly with minimum garden area requirements in Victoria — a larger garage footprint reduces the pervious site area available to meet the mandatory garden area percentage, which can limit overall development yield on tighter lots.
Garage Door Heights: What You Need to Know
The minimum garage door height in Victoria under AS 2890.1 is 2.1m. This clears most standard sedans and hatchbacks. However, a door height of 2.4m is recommended where the garage may be used by:

- SUVs and 4WDs (typical height 1.8–2.0m)
- Vans and people movers (typical height 2.0–2.2m)
- Dual-cab utes with canopies (may reach 2.2m)
If your development includes garages serving multiple dwellings, confirming door height clearance early prevents costly variations during the building permit process.
VC277 Car Parking Reform: How It Affects Garage Requirements
Victoria’s Amendment VC277 car parking reform introduced PTAL-based (Public Transport Accessibility Level) car parking requirements. For development sites with high public transport access scores, the number of required car parking spaces may be reduced, which directly affects garage sizing decisions.
Sites near train stations in areas like Box Hill, Doncaster, and Camberwell may benefit most. A reduced parking requirement means more of the site can be allocated to developable floor area rather than garage space. Check your site’s Clause 52.06 parking rates to understand how PTAL scoring impacts your development.
Developers should check their site’s PTAL score early in the design process, as it may change the garage configuration from the outset.
How Garage Design Affects Development Potential
For developers planning a subdivision or dual occupancy, garage placement and sizing have flow-on effects for the entire site layout. The garage position determines driveway location, which affects crossover requirements and access to rear lots. See our complete guide to townhouse development in Victoria for how garage and parking layout decisions shape overall project feasibility.
In dual occupancy developments, standard parking requirements typically mandate two car spaces per dwelling. Understanding these obligations early helps you allocate site area correctly — a single garage (3.5m × 6m) or double garage (5.5m × 6m) takes up valuable developable space. Our guide to common compliance issues in dual occupancy and townhouse projects covers the most frequent garage and parking errors that trigger planning objections and VCAT appeals.
Garage placement also determines where your driveway meets the street. Understanding the standard driveway width requirements alongside garage dimensions is essential — a single driveway requires a minimum 3m width, while a double garage typically needs a 5–6m driveway at the crossover.
Where a garage conversion is being considered, the existing garage dimensions determine whether the space can be reclassified as habitable without major structural modifications. Conversions must meet NCC standards and local planning scheme requirements.
Developers considering small second dwellings in Melbourne should also note that the car parking space required for the SSD must meet the same minimum dimensions under Clause 52.06 — a 3.5m × 6m internal space minimum — and must be accessible from a public street or laneway. Early confirmation of parking dimensions can determine whether the SSD is feasible on smaller lots.
Avoiding common ResCode pitfalls at the garage design stage matters. Our guide to ResCode variations that kill townhouse projects identifies the most frequent VCAT-trigger compliance failures — many of which relate to car parking layouts and garage setback errors.
Planning Permit vs Building Permit: Garage Requirements in Victoria
Most garage construction in Victoria requires a building permit. A planning permit may also be required depending on zone, overlay, and setback controls. Key triggers include:
- Floor area greater than 10m²
- Height exceeding 3.0m (or 2.4m within 1m of a boundary)
- Attached to an existing dwelling
- Constructed of masonry
- Located in a Heritage Overlay or Design and Development Overlay area
Garages 10m² or smaller that are detached, non-masonry, and within height and setback limits may qualify for a permit exemption — but always confirm with your local council before proceeding. See our guide on building compliance in Victoria for a full breakdown of when permits are required.
