Parking Assignment and Enforcement

Accessible parking at residential facilities is based on the ratio of spaces to dwelling units.

Parking at Residential Facilities

Parking at multi-family residential facility. Notes: Resident Parking (§ Where at least one parking space is provided for each dwelling unit, at least one accessible space is required for each mobility accessible unit. Spaces must be located on the shortest accessible route to the dwelling unit entrance they serve (§208.3.2). Those assigned to specific units are not required to be identified by signs (§216.5, Ex. 2). If the total number of resident spaces is less than the total number of units, accessible parking is based on the scoping table in 208.2 (but providing one accessible space for each mobility accessible unit is advisable). Additional Resident Parking (§ At least 2%, but no fewer than one, of resident parking spaces provided in excess of the one per unit total must comply. These spaces must be dispersed among all types of resident parking except where substantially equal or greater accessibility is provided in terms of distance from an accessible entrance, parking fee, and user convenience (§208.3.2, Ex). Visitor and Other Parking (§ Parking spaces for guests, employees, or other non-residents are subject to the scoping table in 208.2.

Accessible Spaces [§502]

Requirements for accessible spaces address the size and marking of regular and van spaces and access aisles, surfaces, vertical clearance at van spaces, identification, and connecting accessible routes.

Accessible Routes and Access Aisles

Accessible parking space with access aisle adjoined by a curb ramp with a top landing 36” deep min. Accessible route from access aisle on curb ramp and sidewalk highlighted. Notes: Accessible routes must connect directly to access aisles. Curb ramps, where provided, cannot protrude into access aisles (which cannot slope more than 1:48 max.) to accommodate wheelchair transfers and vehicle ramps or lifts (§502.4). A landing at least 36” deep is required at the top of curb ramps; in alterations where space for this landing is unavailable, curb ramps must have side flares with a 1:12 max. slope (§406.4). Bollards, signs, columns, or other elements cannot be located in the access aisle or reduce the minimum clear width of accessible routes. Spaces and aisles must be designed so that parked vehicles do not obstruct the required clear width of adjacent accessible routes (§502.7). Detail: Parallel curb ramp with landing 48” min long, 60” preferred. Note: Where space for curb ramps is limited, including in alterations, parallel ramps can provide an alternative.

design compassRecommendation:  Configure accessible routes so that they run in front of, instead of behind, parking spaces.


Accessible Parking Space

Two accessible parking spaces 8’ wide min. with an access aisle in between that is 5’ wide min. and as long as the space. Notes: Vehicle Spaces (§502.2) Spaces must be marked to define the 96” minimum width. Access Aisle (§502.3) An access aisle at least 60” wide and at least as long as the parking space is required on either side of the parking space and must be marked to discourage parking in it. Two spaces can share one aisle. Access aisles cannot overlap vehicular ways. Surfaces (§502.4) Parking spaces and access aisles must meet requirements for floor and ground surfaces (§302) and cannot have changes in level other than slopes not exceeding 1:48. Markings (§502.1, §502.2, §502.3.3) Both the parking space and access aisle must be marked. The marking method and color is not specified in the Standards, but may be addressed by state or local codes or regulations. Detail: width measured to centerline of marking. Note: The width of spaces and aisles is measured to the centerline of markings (but it can include the full width of lines where there is no adjacent parking space or aisles).

Van Accessible Spaces [§502.1 – 502.5]Person using wheelchair exiting van with ramp parking in accessible van space.

At least one space for every 6 or fraction of 6 accessible spaces must be van accessible. Van spaces provide an additional 3 feet of width to accommodate vehicles equipped with ramps or lifts. This extra space can be added to either the parking space or to the access aisle. A wider access aisle saves space since two spaces can share one aisle, but wider spaces can help prevent misuse of the access aisle as a parking space.


Van Space: Wider Space

Van accessible parking space 132” wide min. and access aisle 60” wide min.


design compassRecommendation:  Sizing all accessible spaces (or access aisles) for van accessibility provides greater convenience and helps ensure that van spaces remain available for those who need them.  Where a van space and regular accessible space share an aisle, it is advisable to have the access aisle serve the van space on the passenger side (as is required where van spaces are angled) since backing into spaces can be more difficult with vans.

Van Space: Wider Access Aisle

Van accessible parking space 96” wide min. and access aisle 96” wide min.


Angled Van Spaces

Angled van accessible parking spaces with an access aisle on the passenger side of each space.As with regular accessible spaces, van accessible spaces can share a common access aisle. However, where van spaces are angled, an access aisle is required for each space on the passenger side (§502.3.4). This is the side from which ramps and lifts typically deploy.

design compassRecommendation:  Where standard (non-van) accessible spaces are angled or otherwise restrict entry to one direction only, providing one access aisle for each accessible space (or on both sides where only one accessible space is provided) will offer greater usability by accommodating access on either side.  Otherwise, consider designing accessible spaces to permit both front-in and back-in parking.

A 98” minimum vertical clearance is required for van parking spaces/ access aisles and the vehicle route to these spaces from an entrance and from these spaces to an exit. Van spaces can be grouped on one level of parking structures.

design compassRecommendation:  Signs at garage entrances that indicate vertical clearances and the location of van spaces are advisable.
