Parking Stall Dimensions
Typical parking space:
9 ft x 18 ft to 10 ft x 20 ft
Compact/small car space:
8 ft x 16 ft (These are not always permitted by zoning or development codes)
Standard handicapped parking space:
96 inches plus 60 inch access aisle
Van Accessible parking space:
96 inches plus 96 inch access aisle
Four basic layouts of parking
1. 90° two-way lot
The smallest amount of wasted space (in corners and aisles)
and is the most efficient
2. Angled one-way lot
Three usual variations: 60°, 45°, and 30° ranging from the
most efficient to the least efficient
3. Two-way angled parking lot
Desirable because of its easy ingress and egress
4.
Parallel parking
Most difficult for people to negotiate & the least efficient
method

The 90° two-way lot configuration
has the smallest amount of wasted
space (in corners and aisles) and is
the most efficient.
Parking and Pedestrian Circulation
ARCH 2006 Architectural Topics IV
Parking layouts less than 90° create two triangles of
wasted area.
The angled one-way lot has three variations: 60°
(the most efficient), 45° and 30° (the least efficient)

Angled one-way parking uses a narrower
aisle width than any two-way system, and
has advantages in situations where oneway systems are necessary or preferable

Parallel parking is the most difficult for
people to negotiate and the least efficient
parking layout. Generally parallel parking
should not be mixed with any other parking
layout, because it creates chances for a
collision as a driver backs out of a space
Parking and Pedestrian Circulation

Single-loaded lots are a common parking strategy
for limited or restricted sites and are very
inefficient because of the larger-than-necessary
isle widths that create a very low ratio of parked
cars to paved area.

Bollard used to protect a building or limit access
Generally parking should be adjacent to a
building unless it is important to avoid the
intrusion of headlights.
Cars never have priority over people. The
critical criterion is always the user's safety.

Accessible Handicapped Parking
Walking distances should be held to a minimum.
Locate so it is not necessary to cross a circulation drive

Accessible Handicapped Parking
All requirements were taken from the ADA Accessibility Guidelines for 4.6 Parking and Passenger Loading
Zones. http://www.adaportal.org/Facility_Access/ADAAG/ADAAG_TOC.html4.1.2(5)(a)
Minimum Number of Spaces
Location
Accessible parking spaces shall be located on the shortest
accessible route of travel from adjacent parking to an accessible
entrance, or in parking facilities that do not serve a particular
building, accessible parking shall be located on the shortest
accessible route of travel to an accessible pedestrian entrance of
the parking facility.
Parking and Pedestrian Circulation
ARCH 2006 Architectural Topics IV
Parking Spaces
Accessible parking spaces shall be at least 96 in wide. Parking
access aisles shall be a minimum of 60 in wide and must be part
of an accessible route to the building or facility entrance. Two
accessible parking spaces may share a common access aisle.
Parking spaces and access aisles shall be level with surface slopes
not exceeding 1:50 (2%) in all directions.
Van Accessible Spaces
The space must be at least 96 in wide with an access isle that is
also 96 in wide. 1 out of every 8 Accessible spaces needs to meet
the “Van Accessible” requirements. If only 1 accessible space is
provided, then it must meet the “van accessible” requirements.

and Access Aisle

Vertical Clearance
At “van accessible” parking spaces, provide minimum vertical
clearance of 98 in at the parking space and along at least one
vehicle access route to such spaces from site entrance(s) and
exit(s). Provide minimum vertical clearance of 114 in at
accessible passenger loading zones and along at least one
vehicle access route to such areas from site entrance(s) and
exit(s).
Signage
Accessible parking spaces shall be
designated as reserved by a sign
showing the symbol of accessibility.
Van accessible spaces shall have an
additional sign "Van Accessible"
mounted below the symbol of
accessibility. Such signs shall be located
so they cannot be obscured by a vehicle
parked in the space.

Passenger Loading Zones
Passenger loading zones shall provide an access aisle at least 60 in
wide and 20 ft (240 inches) long adjacent and parallel to the
vehicle pull-up space. If there are curbs between the access aisle
and the vehicle pull-up space, then an accessible curb ramp shall
be provided. Vehicle standing spaces and access aisles shall be
level with surface slopes not exceeding 1:50 (2%) in all directions.
1. Access aisle depth is at least 5 feet.
2. Access aisle length is at least 20 feet. 3.
3. Curb ramp connects the access aisle for the accessible drop-off area (which
is at the level of the parking lot) to the accessible route to the accessible
entrance.
