ADAAG Manual

Angled (Front-In) Parking

ADAAG's requirement for an access aisle on either side of a space (they can be shared by two spaces) is based on the assumption that drivers can head in or back in as needed. While not specifically addressed in ADAAG, spaces that allow only head-in parking do not afford this same level of flexibility. Recommendation: Where possible, locate accessible spaces in areas where drivers have the option of backing in or consider providing an access aisle at each space so that in series an aisle is available on both sides, thereby allowing use of an aisle on both the driver and passenger sides.
