Reserved spaces for people with disabilities
A proportion of car parking spaces must be reserved for people with disabilities in accordance with best practice, and this requirement applies regardless of any overall reduction in parking provision.
In assessing car parking provision the Department will require that a proportion of the spaces to be provided are reserved for people with disabilities in accordance with best practice. Where a reduced level of car parking provision is applied or accepted, this will not normally apply to the number of reserved spaces to be provided.
