From single home driveways to large commercial car parks, a complete guide to Australian standards, dimensions, and smart planning advice.
It might seem like a small detail, but get the dimensions wrong and you're looking at a long list of problems. Spaces that are too narrow cause door dings and accidents. Spaces that are too short leave bumpers hanging over pathways. And spaces that don't account for turning circles leave drivers going back and forth just to get in and out.
From a legal standpoint, non-compliant parking areas can lead to failed building inspections or council rejections during development approval. For commercial sites especially, this can mean costly delays or mandatory redesigns.
And from a practical standpoint, people just want to park comfortably. A well-designed car park makes a property look professional and well-planned. That matters whether it's a school, a shopping centre, or a private home.
One of the most common mistakes we see is clients who planned their car park layout themselves and went right to the minimum 2.4 m bay width. It looks fine on paper, but once the asphalt is down and cars start parking, the complaints start almost immediately. Going even 15 cm wider per bay adds almost nothing to your overall project cost, but it makes a world of difference to daily usability.
According to AS 2890.1, here are the most commonly referenced minimum dimensions for standard parking spaces. These are minimum dimensions, and "minimum" is the key word. If space allows, going slightly wider (2.6 m to 2.7 m) makes a noticeable difference to everyday usability, especially in areas where people are loading shopping, using prams, or getting in and out of larger vehicles.
| Space Type | Min. Width | Min. Length |
|---|---|---|
| Standard parking space | 2.4 m | 5.4 m |
| Space adjacent to wall or obstruction | 2.7 m | 5.4 m |
| Disabled / accessible parking | 3.2 m (incl. 0.8 m shared zone) | 5.4 m |
| Small car space (designated) | 2.2 m | 4.9 m |
Australia's roads have changed. The average passenger vehicle is bigger than it was when some of these standards were written. SUVs, utes, and large family wagons are now the norm rather than the exception. A Toyota LandCruiser or Ford Ranger is going to feel very cramped in a 2.4 m space.
For properties where larger vehicles are common, rural homes, commercial fleets, or trade businesses, it's worth planning for spaces of at least 2.7 m wide and 5.5 m to 6.0 m long. It costs very little extra in asphalt or space planning, and it saves a lot of frustration down the track.
Across the jobs we've completed for trade businesses and rural clients, we almost always recommend a minimum 2.7 m width as the starting point, not 2.4 m. With utes and dual-cabs now making up such a large share of Australian vehicles, the standard minimum is simply outdated for many real-world situations.
For homeowners, the requirements are primarily governed by local council planning rules, which typically reference AS 2890.6, the standard for residential parking.
A single residential parking space must be at least 2.6 m wide by 5.4 m long for uncovered or driveway parking. For garages, clearance matters too, you'll generally need a minimum internal garage width of 3.0 m to make getting in and out of the vehicle comfortable.
Councils in most Australian states also require a minimum driveway width of around 3.0 m for single vehicle access, and up to 5.5 m for dual access. Check with your local council, as requirements vary slightly between NSW, VIC, QLD, WA, SA, and other states.
When we're laying a residential driveway, we always have a conversation about future-proofing. If you think you might upgrade to a larger vehicle in the next five to ten years, or if you have visitors with vans or utes, build to 3.2 m or 3.4 m from the start. Widening a driveway after the fact is entirely possible, but it costs more than getting it right the first time.
Two cars side by side? Plan for at least 5.4 m wide by 5.4 m long as an absolute minimum for a double tandem arrangement, or 5.5 m wide by 5.4 m long for side-by-side parking. Again, being generous here pays off in everyday convenience.
Always leave enough room for a car door to fully open, roughly 0.5 m, when planning the space between a parking bay and a wall, fence, or structure.
Every scenario above at a glance, so you don't have to scroll back to check a number while you're planning.
Commercial car parks are a different beast. You've got more vehicles, higher turnover, and often a mix of user types, including customers with disabilities, families with prams, delivery vehicles, and regular passenger cars.
AS 2890.1 governs commercial, retail, and mixed-use parking. Standard bays in a commercial setting are typically 2.4 m wide by 5.4 m long, with aisle widths determined by the parking angle used.
The angle of your parking bays directly affects how much aisle space you need for safe vehicle manoeuvring.
| Angle | Aisle Width | Notes |
|---|---|---|
| 90° Perpendicular | 6.2 m aisle (two-way) | Most efficient use of land |
| 60° Angled | 4.5–5.5 m aisle | Easier in/out, one-way aisles typical |
| 45° Diagonal | 3.5–4.5 m aisle | Best for one-way layouts, good for smaller sites |
| Parallel | 3.3 m (one-way) | Common on streets, not ideal for off-street |
In smaller commercial sites, think local medical centres, childcare facilities, or suburban retail, we consistently find that 90-degree bays with a proper 6.5 m aisle dramatically reduce the number of low-speed scrapes and reversing incidents. The extra 30 cm of aisle space costs almost nothing at the time of laying, but clients tell us it makes a genuine difference to how smoothly their car park flows day to day.
Australian building codes under the National Construction Code (NCC) and the Disability Discrimination Act (DDA) require accessible parking bays in commercial developments.
DDA-compliant spaces are one of the areas we see cut corners on most frequently, especially when a site is tight on space. The shared zone between accessible bays often gets treated as optional or gets absorbed into the bay width. It isn't optional, and it will get flagged during inspection. We always mark these out clearly before laying so there are no surprises at sign-off.
Schools, hospitals, and other public institutions have their own unique parking challenges. There's peak traffic during drop-off and pick-up times, constant pedestrian movement across the car park, and a mix of staff, visitor, and bus parking areas.
For school grounds, parking areas should meet standard AS 2890.1 dimensions, but the design also needs to account for additional layout requirements.
The most overlooked element in school car park design isn't the bay size, it's the flow. How cars enter, queue, drop off, and exit during that 10-minute morning window needs to be thought through at the planning stage, not fixed with a cone and a sign after the fact. We always walk school clients through peak-hour circulation before any asphalt goes down.
Recreation and sporting facilities bring their own parking demands, typically weekend peak loads, group arrivals, and the need for spaces that accommodate trailers and larger vehicles carrying sports equipment.
For these settings, spaces of at least 2.7 m wide by 5.5 m long are strongly recommended. Allow for additional space near entry points for trailer and equipment offloading. Clear pedestrian paths from parking areas to court entries should also be part of any site design.
Because these sites often sit unused during the week and then see heavy use on weekends, the asphalt needs to be laid with appropriate compaction and base depth to handle that stop-start load pattern. A thinner residential-spec asphalt layer won't hold up. We spec these projects the same way we would a light commercial site.
Even perfectly planned parking dimensions become a problem if the surface underneath is in poor shape. Cracked, pothole or uneven asphalt creates hazards for vehicles and pedestrians alike. Good line marking only sticks and stays visible on a quality surface, on a crumbling or patched-up car park, it quickly fades or chips.
Whether you're laying a new car park from scratch or repairing an existing one, a properly compacted, professionally laid asphalt surface is the starting point. This includes correct base preparation, drainage grading, and finish depth appropriate for the expected traffic load.
We typically recommend asphalt over concrete for projects where future utility access, budget flexibility, or long-term maintenance ease are priorities. Asphalt can be patched, resurfaced, and re-marked without tearing up the entire area. For a commercial or school car park that will see decades of use, that repairability factor is genuinely valuable, and something concrete simply can't match at the same cost.
For commercial sites and schools especially, line marking needs to clearly define the following.
While AS 2890.1 and AS 2890.6 provide the national framework, local councils across Australia can impose additional requirements. In densely populated urban areas of Sydney, Melbourne, or Brisbane, minimum car park dimensions might be slightly adjusted based on council development control plans (DCPs).
Always confirm with your local council before finalising any car park design, particularly for new subdivisions, commercial developments, or projects requiring development approval. A good asphalt contractor will factor these into their planning and site layout recommendations from day one.
Don't rely solely on the Australian Standard dimensions when submitting for DA approval. We've seen projects delayed because the applicant used AS minimums but the local council DCP required slightly different setbacks or aisle widths. Always cross-check both documents before locking in your layout.

Get a Free Quote TodayThe minimum standard parking spot size under AS 2890.1 is 2.4 m wide by 5.4 m long. However, spaces adjacent to walls or obstructions require a minimum width of 2.7 m, and accessible spaces require at least 3.2 m wide.
For most residential driveways, a council crossover permit is required. For commercial car parks or new residential developments, a full development application (DA) may be needed. Requirements vary by local government area, so it's always worth checking early in the planning process.
Generally, at least 1 accessible space for every 50 standard spaces is required, with a minimum of one accessible space in any new commercial development. The NCC and DDA set out detailed requirements for placement, dimensions, and path of travel.
Asphalt is widely used across Australia for commercial car parks due to its durability, cost-effectiveness, and ease of repair. It handles heavy vehicle loads well, can be graded for proper drainage, and provides a clean surface for line marking. Concrete is an alternative but comes at a higher upfront cost.
A double-width driveway for two vehicles side by side should be at least 5.5 m wide. For tandem parking (one car behind the other), a width of 3.0 m and a length of around 10.8 m is generally needed.
Getting your parking spot size right isn't just about ticking a compliance box, it's about creating a space that actually works for the people using it every day. From the family driveway to the school car park to the busy commercial centre, proper dimensions, quality asphalt, and clear line marking all work together to make parking safe, efficient, and stress-free.
If you're planning a new car park, driveway, or pathway anywhere in Australia, or you're looking to repair and refresh an existing one, the team at MR Asphalt is ready to help. We understand the Australian standards, we know what councils look for, and we deliver work that lasts.
