Parking is any type of space used to store a vehicle. Parking can be on-street, surface lots, in underground or above ground garages, or in a "woonerf." Parking may be part of a residential property, publicly provided, or commercially provided. Parking may or may not have an explicit, implicit, implied, actual, subsidized, or out-of-pocket cost. Regulations may also determine the cost and time limits (if any) to park on public streets, and the minimum or maximum amount of parking required for certain uses.
