Accessible and blue badge parking in new development

Accessible parking provision in planning is set by three things at once: the Building Regulations dimensions, the policy quantum in the development plan, and the public sector equality duty that sits over the decision itself. Get the bay dimensions right and the quantum wrong, or the quantum right and the route to the entrance wrong, and the scheme still attracts an objection from the access officer.

The bay itself is the easy part. A designated bay is 2,400 millimetres wide by 4,800 millimetres long, with a 1,200 millimetre access zone alongside and a further 1,200 millimetre zone at the rear where the bay is perpendicular to the route. That gives an overall footprint of 3,600 by 6,000 millimetres for a single bay.

Provision levels set by policy

Quantum comes from the local plan, from the Building Regulations guidance and from the relevant national standard, and the three do not always agree.

For buildings other than dwellings, the usual starting figures are one bay for each disabled employee, plus around 5 per cent of total capacity for visitors at a workplace, rising to about 6 per cent at shopping, recreation and leisure destinations. Those are recommendations rather than statutory minimums, and a local plan parking standard can require more.

Residential provision works differently. In London the plan requires at least one designated bay for 3 per cent of dwellings from the outset, with the capability to provide a further 7 per cent on demand, giving a 10 per cent total. Authorities outside London commonly adopt a similar structure through their own parking standards, often expressed as a percentage of dwellings with a demonstrated route to increasing it.

The "on demand" element is what catches applicants. It requires the layout to show where the additional bays would go, with the space physically available and the surfacing and drainage capable of conversion. A note saying additional bays will be provided if needed, with no plan showing where, fails.

Where a scheme proposes lower provision than the standard, the case has to rest on evidence rather than on assertion. A Parking Survey showing existing stress and usage patterns is the usual foundation, and the same discipline that applies to general parking quantum applies here.

Bay dimensions and transfer zones

The access zone is the part most often eroded during detailed design.

• The 1,200 millimetre side zone allows a wheelchair to be transferred beside the vehicle. It must be at carriageway level, hatched, and free of bollards, lighting columns, drainage channels and planting.
• Where two bays sit side by side, they may share a single access zone between them, which saves 1,200 millimetres across the pair.
• The rear zone allows access to a boot-mounted hoist or a rear-entry vehicle, and it is needed where the bay abuts a footway or a wall rather than an open route.
• Bays should be level. A gradient no steeper than 1 in 50 in any direction is the figure to design to, and a cross-fall steeper than that makes transfer unsafe.
• Surface treatment must be firm, even and slip resistant. Gravel, grass reinforcement and block paving with wide joints are all unsuitable.

For dwellings built to the wheelchair user standard, the parking space needs the same access zone, or the plot has to be arranged so the space can be widened later without moving a boundary or a service run.

Distance to the entrance and the route surface

Bays should sit as close as possible to the accessible entrance, and 50 metres is the maximum travel distance generally applied for off-street parking. Distance alone is not the test though. The route matters more.

What the route needs: a continuous accessible surface with no steps, dropped kerbs flush with the carriageway where it crosses a road, a minimum clear width that allows two wheelchair users to pass, tactile paving at crossings, and lighting to the same standard as the rest of the pedestrian network.

What defeats it: a route that crosses a service yard, a route that shares a narrow vehicle entrance, a route with a gate needing two hands to open, and the very common failure of a bay placed 20 metres from the door with a raised kerb and no dropped crossing between them.

Draw the route on the site plan as a line with a dimension, not as an assumption. Where the route crosses a private drive or a shared surface, check the geometry against private drive geometry, gradients, widths and turning.

Parking for wheelchair user dwellings

Dwellings built to the wheelchair user access standard need a parking space that works with the dwelling, which means adjacent or as close as the layout allows, with the access zone, and with a level approach to the dwelling entrance.

Two practical points. A garage does not count as an accessible space unless it is wide enough for the access zone with the door open, which standard single garages are not. And a space on a shared parking court needs the route from it to the dwelling to be accessible, which in practice usually rules out arrangements where the court sits behind a terrace and the accessible entrance faces the street.

Enforcement and management of bays

A designated bay that anyone can park in is not provision, and this is the point where planning reaches the limits of what it can control.

On the public highway, a designated bay needs a traffic regulation order to be enforceable, which is a separate process run by the highway authority and takes months. On private land, enforcement depends on the lease, the management company or a parking operator, and the planning system can secure the arrangement only indirectly.

The mechanisms that work:

1. A condition requiring the bays to be marked and signed in accordance with the approved drawings and retained thereafter.
2. A management plan secured by condition or obligation, setting out how bays are allocated, monitored and enforced.
3. For residential schemes, allocation of designated bays to the wheelchair user dwellings in the transfer or lease rather than by a sign alone.
4. A commitment in the obligation to fund the traffic regulation order where bays sit on land to be adopted.

Where the applicant is a public body, or where the decision engages the authority's own duties, an Equalities Impact Assessment sets out how the proposal was tested against the public sector equality duty under the Equality Act 2010. That duty applies to the local planning authority as decision-maker, and a scheme that under-provides accessible parking puts the officer in the position of having to justify the decision against it.

Charging points at accessible bays

Charge point provision is now a Building Regulations requirement for new development, and accessible bays need particular attention because a standard installation frequently makes the bay unusable.

The problems are physical. A bollard-mounted unit placed in the access zone blocks the transfer space. A heavy cable is difficult to handle from a seated position. A unit mounted at standard height cannot be reached. A kerb between the bay and the unit is an obstacle.

The accessible charging specification published for this purpose deals with reach ranges, cable weight, unit positioning, bay dimensions with charging equipment, and the surrounding circulation. Design at least one accessible bay per charging cluster to it, keep the unit out of the access zone, and mount the socket within the reach range rather than at the installer's default height.

Where charge points are added later under a management arrangement, the condition should require the accessible bays to retain their access zones. Retrofit installations are the most common way a compliant layout becomes non-compliant.

Evidencing compliance in the submission

A short annotated drawing answers most of the questions an access officer will raise:

• Every designated bay dimensioned, with access zones hatched and labelled.
• The accessible route from each bay to each accessible entrance, drawn and dimensioned, with gradients noted.
• The provision calculation, showing the policy standard applied and the resulting number.
• The location of the reserve bays where a proportion is provided on demand.
• Charge point positions relative to access zones.
• Surface specifications for bays and routes.

Put the calculation in the Transport Statement as well, so the transport and access cases tell the same story.

One honest caveat: standards for residential accessible parking vary more between authorities than almost any other parking requirement, and a London borough's expectations will differ substantially from a district council's. Read the adopted parking standard before applying a national figure.
