Parking guidance for new developments

Last updated: 22 September 2022

8. Dimensions for car parking

Evidence shows that the size of vehicles has increased over time. As a result, the size of parking spaces has been reviewed, and the size increased for both residential and non-residential parking, to better reflect the current size of vehicles. Table 8 sets out the minimum bay size for cars.

Table 9. Minimum car parking dimensions
Length Width
5.0m 2.8m

The minimum bay size must be used unless developer evidence suggests otherwise. If spaces are smaller than the minimum bay size, the bay will no longer be considered a usable parking space. Where spaces are constrained by a wall on one side, which may consequently prevent a door from opening, the space may need to be larger. Increasing the length of an on-street parking bay may also need to be considered for parallel parking.

Table 10. Minimum parallel parking dimensions
Length Width
6.0m 3.0m

Parking spaces in front of a garage or vertical feature would require a 5.5m space for access to the car boot.

There should be a distance of 6.5m between rows for access where the parking spaces are at right angles to the traffic lane. The distance between rows can be reduced where the parking spaces are at angles to the traffic lane.

Wider car parking spaces should be provided for blue badge holders (see section 2.7.2).

Unallocated on-street parking spaces (kerbside parking or marked bays) may be considered for adoption by the Highway Authority subject to operational and safety considerations. However, where there is allocated parking provision for individual dwellings which is not adopted by the Highway Authority, the developer will have to provide the appropriate arrangements for their future management and maintenance. In some cases, the district councils may also be delegated the management of on-street parking where appropriate.
