Disabled person parking spaces
An appropriate proportion of parking spaces must be reserved for people with disabilities, conveniently located to provide easy access to buildings, with standards detailed in the Department's 'Access for All' guide.
Given that the car is often the only form of transport available to many people with disabilities developers will be required to reserve an appropriate proportion of parking spaces to meet the needs of people with disabilities. Such designated parking spaces should be conveniently located to facilitate ease of access to the buildings they serve in order to take account of the limited mobility range of many disabled people. Best practice on the number, size and layout of reserved parking spaces is set out in the Department's guide 'Access for All'.
