AS/NZS 2890.1: Complete Guide to Carpark Standards |
AS/NZS 2890.1:2021 sets mandatory requirements for carpark design and line marking.
AS/NZS 2890.1: Complete Guide to Carpark Standards
A property developer in Box Hill submitted carpark plans for a new apartment complex. Council rejected them twice. The bay dimensions were 50mm too narrow under AS/NZS 2890.1:2021. Two months of redesign and resubmission delayed the entire project.
AS/NZS 2890.1 is the Australian and New Zealand Standard for off-street parking facilities. It governs everything from bay dimensions to line marking specifications. Whether you're designing a new carpark or maintaining an existing one, understanding this standard is essential.
What AS/NZS 2890.1 Covers
The standard provides requirements for off-street car parking facilities including design, layout, and construction. The current version is AS/NZS 2890.1:2021, which updated the 2004 edition. — see our carpark line marking services
Key Areas Covered:
- Parking bay dimensions and angles
- Aisle widths for different parking configurations
- Circulation roadway requirements
- Ramp grades and transitions
- Line marking and signage specifications
- Pedestrian facilities within carparks
- Lighting and safety requirements
Standard Parking Bay Dimensions
Bay dimensions depend on the user class. AS/NZS 2890.1 defines three user classes based on parking duration and frequency. — see our accessible parking marking services
User Class 1 (Short-term, high turnover):
Shopping centres, medical centres, short-stay visitors. These users need wider bays because they park infrequently and need easier access.
- Bay width: 2.5m minimum
- Bay length: 5.4m for 90-degree parking
User Class 2 (Medium-term):
Office workers, students, regular visitors. These users park more frequently and can manage slightly narrower bays.
- Bay width: 2.4m minimum
- Bay length: 5.4m for 90-degree parking
User Class 3 (Long-term, regular users):
Residential, commuter parking, employee parking. Daily users familiar with the facility.
- Bay width: 2.3m minimum (2.4m where adjacent to obstruction)
- Bay length: 5.4m for 90-degree parking
Aisle Width Requirements
Aisle width depends on parking angle and whether traffic is one-way or two-way. Narrower aisles are permitted for angled parking because less turning space is required.
90-Degree Parking (User Class 2):
- One-way aisle: 5.8m minimum
- Two-way aisle: 6.2m minimum
60-Degree Parking:
- One-way aisle: 4.0m minimum
45-Degree Parking:
- One-way aisle: 3.5m minimum
Line Marking Specifications
AS/NZS 2890.1 specifies requirements for line marking including width, colour, and placement.
Line Width:
- Bay delineation lines: 75-100mm width
- Edge lines and lane lines: 75-100mm width
- Stop lines: 200-300mm width
Colours:
- White: Standard bay lines, directional arrows, text
- Yellow: No parking zones, loading zones, clearways
- Blue: Accessible parking bays (symbol and shared area)
2021 Updates and Changes
The 2021 revision introduced several important changes from the 2004 version that facility managers should be aware of.
Key Changes:
- Updated design vehicle dimensions (vehicles are larger than 2004)
- Revised user class definitions
- Enhanced pedestrian safety requirements
- New provisions for electric vehicle charging spaces
- Updated references to AS/NZS 2890.6 for accessible parking

Frequently Asked Questions
Is AS/NZS 2890.1 mandatory?
The standard itself is not law, but it's referenced by the National Construction Code and local planning schemes. Most councils require compliance for new developments and major renovations.
Do existing carparks need to comply with the 2021 version?
Generally, existing carparks are assessed against the standard applicable when they were built. However, major renovations or change of use may trigger upgrade requirements. — see our line marking removal services
Where can I get a copy of AS/NZS 2890.1?
The standard is available for purchase from Standards Australia (standards.org.au). Many public libraries also provide access through SAI Global subscriptions. — see our accessible parking requirements under AS/NZS 2890.6 services

Frequently Asked Questions
What is AS/NZS 2890.1?
AS/NZS 2890.1 is the Australian and New Zealand Standard for off-street car parking facilities, published by Standards Australia. The current edition, AS/NZS 2890.1:2021, replaced the 2004 version and sets requirements for parking bay dimensions, aisle widths, circulation roadways, ramp grades, and line marking in off-street carparks.
What is the standard car parking bay size in Australia?
Under AS/NZS 2890.1:2021, a standard long-term (User Class 1A) parking bay measures 2.4 metres wide by 5.4 metres long, while short-term retail bays (User Class 3A) widen to 2.6 metres. Bay width increases with how frequently drivers turn the space over.
What is the minimum aisle width for 90-degree parking?
AS/NZS 2890.1 sets the aisle width for 90-degree (perpendicular) parking between roughly 5.8 and 6.2 metres, depending on the user class. The aisle must allow a vehicle to enter and leave a bay in a single movement. Angled parking at 45 or 60 degrees needs narrower aisles.
What is the difference between AS/NZS 2890.1 and AS/NZS 2890.6?
AS/NZS 2890.1 covers general off-street parking, while AS/NZS 2890.6 governs accessible (disabled) parking. A 2890.6 accessible bay is 2.4 metres wide plus a 2.4-metre shared zone (4.8 metres total) and 5.4 metres long, with a bollard and compliant signage.
Do private carparks have to comply with AS/NZS 2890.1?
Private carparks in Australia generally must comply with AS/NZS 2890.1, because local councils reference it in development approvals and the National Construction Code adopts it. Non-compliant bay dimensions are a common reason councils reject carpark plans, forcing costly redesign and resubmission.
