<P> Another ad hoc arrangement is tandem parking . This is sometimes done with residential motor vehicle parking where two motor vehicles park nose - to - end in tandem . The first motor vehicle does not have independent access, and the second motor vehicle must move to provide access . As with attendant parking, the purpose is to maximize the number of motor vehicles that can park in a limited space . </P> <P> In parking lots, parking is allowed only where marked . </P> <P> In North America, the width of parking spaces usually ranges from 7.0 to 9.0 feet (2.1--2.7 m). Angled and perpendicular spaces may need to be wide to allow doors to open, while parallel parking spots may be as narrow as 6.0 feet (1.8 m) on narrow, low - traffic neighborhood streets . </P> <P> Because the boundary between parking space and driving area is not always well - defined, the length of a parking space is more difficult to establish . However, most angled and perpendicular spaces are considered to be between 10 and 18 feet (3.0--5.5 m) in length . In the United States, due to vehicles being larger on average than some other countries, a parking space 10 feet (3.0 m) deep is uncommon and most parking spaces will be within 16 to 20 feet (4.9--6.1 m), with 19 feet (5.8 m) feet deep being the standard DOT recommended depth for standard perpendicular parking . Parallel parking spaces typically range from 20 to 24 feet (6.1--7.3 m) long . </P>
