Accessibility Fundamentals

Accessibility FundamentalsThis publication provides basic components of the accessibility provisions of the Virginia Uniform Statewide Building Code (USBC). The information herein is not representative of all the requirements you may encounter when designing and preparing construction documents. Frequently asked questions are available for more information.  The dimensions above the dimension lines in the figures below are in inches, and the dimensions below are in millimeters. 



BUILDING CODE

The Code of Virginia requires that your new building or new tenant space complies with the 2003 USBC which incorporates the 2003 International Building Code and the ICC/ANSI A117.1-2003, "Accessible and Usable Buildings and Facilities."

Please note: While the spirit and intent of the Americans With Disabilities Act and the building code are the same, the technical provisions are not. A new building or renovated space must be carefully designed to meet the requirements of both laws. However, Fairfax County only enforces state law, and therefore this publication does not include any information regarding the ADA.

 

BUILDING BLOCKS FOR ACCESSIBLE CONSTRUCTION

WHEELCHAIR REQUIREMENTS

The clear floor space required to accommodate a wheelchair and its occupant is shown in Figure 1. For a wheelchair user to make a 180° degree turn, a circular floor space is required, see Figure 2. An alternate to the circular floor space is a T-shaped space; see ICC/ANSI A117.1 for more information.

ACCESSIBLE ROUTE

An accessible route is a path which connects accessible spaces. It includes paths from accessible parking to the building entrance, restrooms, drinking fountains, corridors, hallways, ramps, elevators, etc. The clear width of an accessible route and the minimum width when passing by an obstruction is shown in Figure 3. Doors within an accessible route must meet the requirements shown in Figure 3. Doors within an accessible route must meet requirements shown in Figure 4 for pull side; see ICC/ANSI A117.1 for push side requirements.

TOILET FACILITIES

At least one of each fixture type (i.e., lavatory, water closet) provided in all public toilet rooms shall be accessible. See Figures 5- 9 for more information. All accessible toilet rooms shall be provided with unobstructed wheelchair turning space (Figure 2) and all accessible fixtures shall also have an unobstructed clear floor space. In multiple user toilet rooms, at least one toilet stall shall be wheelchair accessible. When six or more water closets are provided, at least one additional stall shall be ambulatory accessible. See ICC/ANSI A117.1 for more information.

CODE TIPS

  • A door may swing into the wheelchair turning space.
  • Fixtures may not encroach into the clear floor space of other fixtures. However, fixture clear floor spaces and the wheelchair turning space may overlap.

 

ALTERATIONS TO EXISTING CONSTRUCTION

Alterations and new components to a space or area in an existing building shall be fully accessible. The accessible route to the altered area must be upgraded up to a limitation of 20 percent of the cost of the alterations (this includes mechanical, electrical and plumbing).

For example: A new office tenant is to fill a suite at an existing office building. The alteration in the suite include new offices, corridors and open office area. Cost: $100,000. Therefore, an additional $20,000 or 20 percent of the project cost, must spent to upgrade the accessible route.

COMMON IMPROVEMENTS TO UPGRADE THE ACCESSIBLE ROUTE

  • Accessible entrance
  • Wheelchair accessible toilets
  • Accessible lavatories
  • Accessible drinking fountains
  • Door clearances
  • Levered door hardware
  • Signage
  • Accessible elevators

 

CHANGE OF USE OR OCCUPANCY

When a space undergoes a change of use or change of occupancy, it must be upgraded to meet the requirements of new construction, unless technically infeasible. In addition, the existing building must also be upgraded to meet all of the items listed below:

  1. At least on accessible entrance
  2. At least one accessible route from an accessible entrance to the primary function areas (this includes elevators)
  3. Signage
  4. Accessible parking
  5. At least one accessible passenger loading zone (when one is provided)
  6. At least one accessible route connecting parking, loading zone and entrance.

For more information, please refer to Section 3409.3 of the 2003 International Building Code.

Technically Infeasible: when providing an accessible element would involve the removal or alteration of a structural member that is an essential part of the structural frame.

 

UPGRADING TOILET FACILITIES

The extent to which an existing toilet room is to be upgraded depends on the existing conditions.

  1. UNISEX TOILET: A unisex toilet room (Figure 9) on the same floor as the alterations may be installed ONLY IF technically infeasible or the existing number of fixtures cannot be reduced.
  2. ADA UPGRADES: If the building where the alterations are taking place was upgraded between 1991 and 1997 and a standard stall (60 inches), an alternate stall (48 inches), or a single user toilet room was installed in accordance with the ADAAG, then the existing stalls or toilet room is not required to be upgraded.
  3. FULLY ACCESSIBLE STALLS: All restrooms not meeting any of the above conditions must be upgraded to meet the accessibility requirements of the current code.

UPGRADE TIPS

  • If the cost of upgrading both men's and women's restrooms exceeds the computed cost limit, it is permissible to upgrade one sex only.
  • If the cost of upgrading the restrooms far exceeds the computed cost limit, then the restrooms should be upgraded as much as possible within the limitation, e.g., add grab bars to an existing stall, lower fixtures, etc.
  • Wheelchair accessible stalls are NOT required to be placed at the end of a line of toilet stalls.
 

ACCESSIBILITY COMPLIANCE FORM

When plans are submitted to Fairfax County for review, an Accessibility Compliance Form (PDF) must be fully completed by the project designer and attached to each set of plans. It is the responsibility of the designer to ensure the altered space, accessible route, and upgrades meet the provisions of the code.
