Extract from the parking place regulations
§ 48 Parking spaces for motor vehicles and bicycles
(1) If structural facilities and other facilities are erected where access and departure traffic is to be expected, parking spaces for motor vehicles and bicycles of suitable quality shall be provided or evidenced on the property or, secured by obligatory building criteria, on a suitable property in the vicinity (necessary motor vehicle parking spaces and necessary bicycle places). Their number and size shall be determined by the type and number of existing and expected motor vehicles and bicycles of the permanent users and visitors of the facilities. In the event of changes to the facility and changes in use which result in changes in the number and size of the necessary parking spaces and necessary bicycle places in accordance with sentence 2, only parking spaces and bicycle spaces for the additional requirements as a result of the changes shall be constructed.
(2) The accommodation of children's play areas and necessary bicycle spaces on the property shall have priority over the accommodation of motor vehicle parking spaces.

Summary: Number and size according to the type and number of existing and expected motor vehicles and bicycles of permanent users and visitors to the facilities.
