Car Park Size may seem straightforward, but if you're marking up a plan, it can get complex very quickly. There is no magic number in Australia that works for all sites. In Victoria, planning advice is that the design standard for car parking spaces and accessways is Clause 52.06-9, which may vary from AS/NZS 2890.1, but in NSW, the Housing SEPP says a hard stand car parking space must be at least 2.6m by 5.4m in dimension.
If you are a property owner, the key thing to keep in mind is that the "right" Car Park Size will vary depending on the type of site, local planning requirements, and the intended use. A bay that is suitable for a residential site may not be suitable for a busy retail, commercial or mixed-use development.
Car Park Size is more than just the marked-up spot on the ground. It is also the access lane, the space to allow doors to open, the turnaround, and the movement of traffic in and out. Victoria's planning manual makes it clear that plans must include car parking bays, access lanes, driveways, landscaping and other related works, not just the bays.
A bay is only part of the answer.
A car park bay might seem generous until it is surrounded by walls and columns, fencing, footpaths, kerbs, narrow access lanes or driveways. So a good layout is as important as the bay size. A site can be "big enough" to hold many spaces, but be poorly laid out with poor circulation.
If vehicles can't easily enter and exit, or reverse to find a parking space, it is frustrating to navigate. This is bad for property owners, as poor circulation can result in damage, complaints and wasted space. Planning Victoria also points out that car park layout and design are vital to both technical and streetscape performance.
On limited space, every centimetre counts. A small block size, poor configuration or a sloping site can create challenges. Planning Victoria, in particular, states that the dimensions of a site may not allow for car parking on a small lot, so the effect on parking and site uses must be taken into account.
Before building, the final plan should be checked against the council or planning permit. Any subsequent change to the size or layout of the car park may require a permit or new plans to the satisfaction of the authority. So it's better to get the measurements right from the start.
The first question many people ask is, "What is the standard size?" A good rule of thumb is 2.6 x 5.4m, which is in the NSW planning legislation for an open hard-stand car parking space. That gives a property owner a good indication of how much space a bay should take up, although the final answer will still depend on the state, council and development.
Clause 52.06-9 (Table 2)
Does not defer to AS/NZS 2890.1:2004. Must be verified against local planning controls.
In Victoria, you need to be careful not to just copy that figure. The note for Victoria states that the design standards for car parking are set out in Clause 52.06-9, and that these use the dimensions in Table 2 rather than AS/NZS 2890.1:2004. What this means is Melbourne (and other) sites must be verified against local planning controls, not just some generic car-parking rule.
Min. 2.6m x 5.4m
Housing SEPP mandates hard stand space dimensions. Garage and access rules also apply.
Residential sites can be different to commercial or mixed-use sites. Some residential properties could have garages, carports, or open hard stand spaces, and the local planning provisions may also include additional conditions on setbacks, access and frontage design. For instance, NSW's Housing SEPP sets minimum sizes for open hard stand spaces and has rules for the design of garages and access.
Accessible parking isn't just wider. It has its own design considerations. Planning Victoria states mandatory disabled car parking spaces must comply with AS 2890.6-2009 and the Building Code of Australia, and can be reduced in width (by 500mm) to allow for the extra length.
This means for property owners, the spaces must be planned from the start. They are generally adjacent to the major pedestrian entrance, and the total distance from the bay to the entrance should be considered, not just the parking bay itself.
Car Park Size and car park count are closely linked. A site may be big enough for several spaces, but still not provide the number of spaces required in the local planning scheme. In Victoria, the number of spaces required is based on the use, the relevant category in Table 1 of Clause 52.06-5 and a schedule in the Parking Overlay. When the use isn't listed, it's up to the responsible authority to determine the number of spaces required based on the policies, surveys, floor area and site features.
So you might see a difference in parking solutions for two sites with the same land size, but different uses. A store, warehouse, doctor's office and a home will not all require the same parking. It's not all about land size.
It's not just the numbers that matter. Planning Victoria also notes that a planning permit can be used to change the minimum or maximum parking rates, but this must be based on a car parking demand assessment. The authority can take into account travel patterns, public transport connections and accessibility, walking and cycling infrastructure, shared parking and the efficiency of the parking spaces over time.
Assuming every bay can be built to the same size everywhere.
Focusing only on the marked space and forgetting about the access lane, turning space, and boundary conditions.
Overlooking the local planning overlay, which can change the number of spaces or the design approach entirely.
Trying to rely on spaces that are not secure or not properly controlled. Planning Victoria warns that shared or off-site parking can sometimes be considered, but car parking spaces on land where no formal or enduring agreement exists should not be relied upon.
The best way to approach Car Park Size is to think in layers. First, identify the local rule that applies to your site. Then check the bay dimensions, the aisle width, the access path, and the number of spaces required. After that, look at accessibility, turning movement, drainage, landscaping, and how vehicles will enter and leave the property.
Identify the planning rule that applies to your site and state.
Check bay size, aisle width and access path requirements.
Confirm the number of spaces required for your specific use.
Consider turning movement, drainage, landscaping and entry/exit.
A good car park is not just legal on paper. It is easy to use, safe to drive through, and sensible for the people who will park there every day. That is why the layout should be designed around real vehicle movement, not only the paint lines.
If you own a property in Australia, the safest approach is to treat Car Park Size as a planning problem, not just a measuring job. The exact bay size may vary, but the principle stays the same: the parking area must suit the site, the use, and the local rules. In Victoria, the approved plan must align with the relevant parking provisions, and in NSW, a standard open hard stand space is at least 2.6m by 5.4m.
A well-planned car park saves space, reduces stress, and makes the property more functional for everyone who uses it. Before you build, it is always worth checking the dimensions carefully and making sure the layout works from the first car in to the last car out.
If you are planning a new car park or upgrading an existing one in Melbourne, get the layout checked before construction starts. The right Car Park Size can save time, reduce rework, and make the whole property easier to use.
