Multi-Storey Carpark Marking: It's Not Just Bays — Here's Everything That Needs to Go Down

The property manager called us in after his tenants had started complaining. Not about parking availability — the 480-bay, five-level carpark was never more than 70% full. The complaints were about people taking 20 minutes to find their car.

Visitors would park on Level 3, do their business, come back, and have no idea where Level 3 was. Level signage was minimal. Bay numbers had faded beyond recognition. Directional arrows were inconsistent or missing. Exit signage didn't match any logical path.

Two of his major tenants had received written complaints from corporate clients about the parking experience. One had threatened not to renew their lease.

We came in and did what we call a full wayfinding audit. Not just measured the bays for compliance — assessed the entire driver experience from entry to exit. Fourteen separate wayfinding deficiencies. Most were marking issues. Some were signage. All were fixable.

Three nights of work. The problem went away.

Why Multi-Storey Carparks Are More Complex Than Surface Carparks

In a surface carpark, a driver who gets confused can see the exit from most positions. Orientation is easy. In a multi-storey carpark, every level looks identical. Without clear marking and signage, drivers genuinely lose orientation.

The consequences range from frustrating (25 minutes to find your car) to serious (wrong-way driving on a ramp, accessing a pedestrian stairwell instead of a vehicle exit). AS/NZS 2890.1 includes specific requirements for multi-storey carparks beyond the standard bay dimension and accessible parking requirements precisely because the complexity creates higher safety risks.

The Full Marking Scope for a Multi-Storey Carpark

Bay Markings

Standard bay dimensions apply: 2,400mm wide x 5,400mm long for 90-degree parking, aisles at minimum 6,200mm for two-way traffic. End bays adjacent to walls require 300mm additional width.

In multi-storey carparks, the end bay issue is particularly common. Columns are more prevalent than in surface carparks, and they often intrude on end bay clearances in ways that weren't properly accounted for in the original marking. We measure every bay adjacent to a column on every multi-storey job.

Bay Numbering

Every bay should have a unique identifier that a driver can use to communicate their location ('I'm in Bay 3G-247'). The numbering system needs to be logical — typically by level, then section, then sequential number — and the numbers need to be large enough to read from a standing position without crouching.

We use 300mm-high bay numbers on multi-storey carparks. Some facilities use 200mm — readable but not easily. At 300mm, numbers are visible from 10 metres away, which means a driver walking down an aisle can read their bay number without approaching each bay.

Bay numbers are typically applied in white paint on the aisle side of each bay, with the level identifier included: '3G-247' not just '247'.

Directional Arrows

Every aisle needs directional arrows indicating the flow of traffic. For two-way aisles, this is a 'two-way traffic' double-headed arrow. For one-way aisles, a single arrow with a clear direction. For circulation aisles that connect levels or zones, larger arrows at every decision point.

The Cheltenham property we mentioned was missing arrows in six aisles completely — the original marking had only done bays and didn't touch directional markings. Drivers were improvising their own directions, creating conflict at blind corners.

Level Identification Markings

Each level needs large-format level identification — typically the level number or letter painted at 600mm+ height on walls at ramp entries and on the floor at lift and stairwell approaches. Bright colours (typically yellow or blue, depending on the facility's colour system) on a contrasting background.

Floor-applied level markings in the approach to lifts and stairwells serve people who are on foot. If I've parked on Level 3 and I need to find Level 3 when I return, a large '3' on the floor near the lift is far more reliable than looking for a sign on the wall.

Accessible Bay Identification and Path Marking

As with all carparks, accessible bays need AS/NZS 2890.6 compliant dimensions, yellow line colour, ISA symbols, and shared zone hatching. In multi-storey carparks, the accessible bays are almost always on the ground level near the lift core — and the path from those bays to the lift needs to be clearly marked as an accessible path.

That path marking is often absent. A wheelchair user who parks in an accessible bay on Level 1 needs a clear, marked path to the lift without having to navigate through vehicle aisles. In most multi-storey carparks this is a 20-30 metre path that takes 30 minutes to mark properly. Rarely done. Should be.

Height Clearance Markings

Multi-storey carparks typically have minimum height clearances on entry ramps and at structural beams within the deck. AS/NZS 2890.1 requires these to be clearly marked. The clearance height is marked on the beam or ceiling surface directly, and a warning marking is applied on the floor 5-10 metres before the clearance point.

We paint height clearances in a yellow background with black text: '2.1m' in 300mm-high lettering at the actual clearance point, and a warning chevron pattern on the floor approach. It looks professional and it prevents the damage claims that come from panel vans and SUVs clipping undeclared low clearances.

Ramp Markings

Entry and exit ramps need the standard lane markings, but also: ramp gradient warnings (for steep ramps), 'GIVE WAY' markings at ramp bottom-of-run where visibility of opposing traffic is limited, and edge delineation lines if the ramp has significant height changes on either side.

We also mark pedestrian crossing points at the bottom of ramps where pedestrians and vehicles conflict. This is more commonly done in modern carparks but absent in many older ones.

The Wayfinding Audit: How We Assess a Multi-Storey Before Quoting

We walk every level, every aisle, every ramp, and every pedestrian path. We document:

• Current bay dimensions (measured, not assumed) and compliance status
• Presence and condition of bay numbering
• Presence and condition of directional arrows at every decision point
• Level identification markings — floor and wall
• Accessible bay compliance — dimensions, symbols, shared zones, path to lifts
• Height clearance markings
• Ramp markings and pedestrian conflict points
• Condition of existing marking (retroreflectivity, wear, delamination)

The audit takes two to three hours for a 300-500 bay multi-storey. We provide the findings in writing with the quote so you know exactly what's compliant, what needs attention, and what we're going to do.

Frequently Asked Questions

How do we plan the staging of a multi-storey carpark remark without closing the whole facility?

One level per night is the standard approach. See our shopping centre staging guide for the detailed methodology — the same principles apply to commercial multi-storey carparks. We provide a full staging schedule with every multi-storey quote.

Our existing bay numbering system is inconsistent across levels — can we redesign it?

Yes. We can redesign the numbering system as part of the remark. New numbering means removing old bay numbers (grinding or water blasting the existing paint) and applying the new system consistently across all levels. We'll include the numbering system design in our proposal for your sign-off before any work starts.

Do you mark both the floor surface and the walls in multi-storey carparks?

We specialise in floor and road surface marking. Wall-mounted signage and suspended signs are outside our scope. For a complete wayfinding solution that includes both floor marking and suspended signage, we can refer you to signage contractors we work alongside on larger projects.
