The number of disabled parking spaces within a structure or module is the total count of automobile parking slots reserved for persons with physical disabilities. These are usually located at the most convenient points in the parking area, so that disabled persons have greater ease of access and do not need to navigate through vehicle traffic.

Disabilities usually include any condition which impedes movement, whether the persons require wheelchairs, crutches, braces, walkers, or simply have difficulty moving around. Their cars must normally be designated with a recognizable sticker, sign, or license plate.

The reservation of the automobile space distinguishes it from ordinary parking. These spaces are included in the total number of parking spaces, so the disability-reserved figure is a subset of that total.
