Disabled Parking Line Marking: AS/NZS 2890.6 Compliance Guide

Why Disabled Parking Compliance Matters

Getting disabled parking line marking right is not optional — it is a legal obligation under multiple layers of Australian legislation. The Disability Discrimination Act 1992 (DDA) makes it unlawful to discriminate against people with disabilities in the provision of access to premises. State building codes reference the Australian Standards that set out the specific technical requirements. Councils actively audit car parks and can issue orders requiring non-compliant facilities to be brought up to standard.

Beyond legal compliance, correctly marked accessible parking bays ensure that people who need them can actually use them — with enough space for wheelchair transfers, accessible paths to building entries and clear identification that deters misuse.

This guide covers everything you need to know about accessible parking line marking in Australia.

Applicable Standards

AS/NZS 2890.6 — Off-Street Parking for People with Disabilities

This is the primary standard governing disabled parking bay dimensions, layout, signage and access paths. It works alongside AS/NZS 2890.1 (general car parking) and references the access and mobility standards.

AS 1428.1 — Design for Access and Mobility: General Requirements

Specifies the accessible path of travel from the parking bay to the building entry. Gradients, widths, surface conditions and tactile indicators are all covered.

AS 1428.4.1 — Means to Assist the Orientation of People with Vision Impairment

Covers tactile ground surface indicators (TGSIs) that may be required along the accessible path connecting the parking bay to the building.

Disability Discrimination Act 1992 (DDA)

The overarching federal legislation. While it does not set specific dimensions, it establishes the legal duty to provide equitable access. The Australian Standards are the accepted method of demonstrating compliance.

Correct Dimensions for Disabled Parking Bays

Under AS/NZS 2890.6, the minimum dimensions for an accessible parking bay are:

• Bay width: 2.4 metres
• Shared zone width: 2.4 metres (adjacent to the bay, for wheelchair transfer)
• Total width per pair: 4.8 metres (one shared zone serves two adjacent bays)
• Bay length: 5.4 metres minimum (same as standard bays under AS/NZS 2890.1)
• Vertical clearance: 2.5 metres minimum (for van-accessible bays and the access route)

The shared zone must be marked with diagonal hatching and must connect to an accessible path of travel at the same level (no kerb). If there is a kerb between the bay and the footpath, a compliant kerb ramp must be provided.

Symbols and Signage

Each bay must display the International Symbol of Accessibility (ISA) — the wheelchair symbol — painted on the bay floor. The symbol should be painted in white on a blue background and located centrally within the bay. A vertical sign displaying the ISA must also be erected at a height visible from the driver's seat of an approaching vehicle.

Minimum Bay Counts

AS/NZS 2890.6 sets out the minimum number of accessible bays based on the total number of parking spaces in the facility:

• 1–50 total bays: 1 accessible bay
• 51–100 total bays: 2 accessible bays
• 101–200 total bays: 3 accessible bays
• 201–300 total bays: 4 accessible bays
• 301–400 total bays: 5 accessible bays
• 401–500 total bays: 6 accessible bays
• 501–1000 total bays: 1 additional bay for each additional 100 bays
• Over 1000 total bays: 1 additional bay for each additional 200 bays

These are minimums. Many facility managers choose to exceed these numbers, particularly at medical centres, hospitals and aged care facilities where demand for accessible parking is higher.

Common Mistakes We See

After marking hundreds of car parks across Australia, these are the most frequent compliance failures we encounter:

Wrong Bay Width

The most common error. Many facilities have bays marked at 2.4 m without the required 2.4 m shared zone. A 2.4 m bay alone does not allow a wheelchair user to open a car door fully and transfer. The shared zone is not optional.

Wrong or Missing Symbol

The ISA must be the correct design — the modern forward-leaning wheelchair symbol is acceptable, but the proportions and colours must be clearly identifiable. Faded symbols or hand-painted approximations do not meet the standard.

Excessive Gradient

Accessible bays must be on surfaces with a maximum gradient of 1:40 (2.5%) in any direction. Placing accessible bays on sloped areas of a car park is a common error that can make the bay unusable for wheelchair users.

No Accessible Path

A compliant bay is useless if there is no accessible path connecting it to the building entrance. The path must comply with AS 1428.1 — minimum 1.0 m wide (1.2 m preferred), gradients not exceeding 1:20, and kerb ramps where level changes occur.

Real Project: Cheltenham Strata Complex

In 2024, we were engaged by a strata management company to audit and re-mark a 120-bay residential complex car park in Cheltenham. The complex had been built in 2008 with two accessible bays — the correct number at the time. However, a body corporate renovation had inadvertently reduced the shared zone to 1.8 m by widening adjacent standard bays.

A resident who used a wheelchair lodged a complaint with the Australian Human Rights Commission. The strata body needed to urgently rectify the non-compliance. We re-marked the accessible bays to the correct 2.4 m + 2.4 m shared zone, repainted the ISA symbols and signage, and provided a compliance certificate referencing AS/NZS 2890.6.

The total cost was modest — around $2,800 — but the strata body had already incurred legal costs responding to the discrimination complaint. Early compliance would have prevented the entire situation.

We see similar scenarios across Frankston, Narre Warren and other growing suburban areas where older car parks need updating.
