Line Marking Services: What You Need to Know About Australian Standards for Car Park Lines

Australian car park line marking standards cover specific bay dimensions, colour rules, and accessibility requirements that every property owner in Perth, WA, should understand before commissioning line marking services.

Non-compliant markings can trigger council enforcement, create liability exposure, and block development approvals. Two Australian Standards sit at the centre of any compliant car park: AS/NZS 2890.1 and AS 1742.

What Is AS/NZS 2890.1 and Why Does It Matter?

AS/NZS 2890.1 is the primary Australian Standard for off-street car parking facilities, governing bay dimensions, aisle widths, ramp gradients, vertical clearances, and sight distances.

Bay Sizing Minimums

For a standard 90-degree bay, the minimum width is 2.4 metres and the minimum length is 5.4 metres. Bays adjacent to a wall or obstruction require an additional 300 mm of width for safe door opening. Aisle widths for 90-degree bays must be at least 6.2 metres for two-way traffic.

A draft revision proposed increasing minimum bay lengths from 5.4 metres to 5.6 metres to reflect the growing share of SUVs and utes on Australian roads. Confirm the current applicable version with your contractor before finalising any layout.

Accessible Parking Under AS/NZS 2890.6

Accessible bays follow companion standard AS/NZS 2890.6. Each bay must be 2.4 metres wide with an adjacent 2.4-metre shared zone, giving a combined marked width of 4.8 metres per pair. The international symbol of access must be painted in the bay centre, and a bollard is required within the shared zone to prevent unauthorised use.

Bay boundary lines must be unbroken and between 80 mm and 100 mm wide. Faded or missing accessible bay markings can attract enforcement action and complaints under the Disability Discrimination Act 1992.

How Does AS 1742 Apply to Car Parks?

AS 1742 covers road markings and traffic control devices. Its principles apply to private roads and car parks where consistent, recognisable markings are required. In Australian car parks, centre lines and lane lines are white. Yellow is reserved for no-stopping zones along kerbs. Using yellow for lane delineation is a common reason council inspectors fail line marking work on private sites.

Directional arrows use scaled-down AS 1742 designs suited to lower-speed environments. Correct colour and arrow specifications help drivers navigate confidently and reduce the risk of incidents.

What Perth Property Managers Need to Know

In Western Australia, line marking must also meet Main Roads WA (MRWA) standards where applicable. Most Perth metropolitan councils embed AS/NZS 2890.1 requirements directly into local planning schemes, meaning non-compliant layouts can lead to Development Application rejection. Perth's high-UV climate accelerates paint fade, making regular condition audits important for maintaining visibility and compliance.

Common compliance failures include bays that are too narrow adjacent to walls or columns, incorrect colour use on directional markings, undersized accessible bay shared zones or missing bollards, and line widths outside the 80 mm to 100 mm requirement.

For warehouses and industrial sites, a compliant warehouse line marking layout keeps forklift and foot traffic clearly separated under WHS legislation.
