The number of parking spaces in a structure or module is the total number of all automobile parking slots, including disabled parking spaces, within that property. Parking slots for motorcycles are not included, but slots for oversized personal vehicles such as vans or SUVs are included. An estimated figure may be admitted if a parking area is not divided into discrete spaces.

Disabled parking spaces form part of this automobile total. Their separate quantity identifies a subset rather than an additional group to add to the overall figure.

The figure describes parking places rather than vehicles currently parked. Where an area lacks marked individual spaces, its estimated capacity stands in for an exact slot count.
