Ignorance of the law shall not excuse noncompliance and it is the responsibility of the citizens to inform themselves as to the laws that are enacted in the United States of America and in the states and cities contained therein. Consensus is established when in the judgement of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests.
Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made a171 their resolution.

Recommendations to Adopting Authorities 1 2. Graphics, Dimensions, Referenced Standards, and Definitions Accessible Elements and Spaces 3 4. Inthe U. Department of Housing and Urban Development joined the Secretariat and sponsored needed research which resulted in the edition.
After further revision that included a special effort to remove application criteria scoping requirementsthe edition was published and, when requested in 1the Council of American Building Officials CABO assumed the Secretariat. Central to the intent of the change in the Secretariat was the development of a standard that, when adopted as snsi of a building code, would be compatible with the building code and its enforcement.
ANSI A117.1 (1992): Accessible and Usable Buildings and Facilities
This edition has largely achieved that goal. For this 19992, substantial effort was devoted to removing from the Standard informational statements and application criteria scoping requirements such nasi where, when, and to what extent the criteria will apply to the built environment. In furtherance of that effort, all figures were moved to an appendix to emphasize that they are to illustrate, not establish, the criteria. The appendices are not part of the Standard; therefore, should a andi appear to illustrate criteria that differ with the text of the Standard, the criteria stated in the text govern because the figure is contained in an appendix.
Suggestions for improving this edition will be welcome. Committee approval of the Standard does not necessarily imply that all Committee members voted for its approval.
At the time it approved this Standard, the A Committee had the following members: Reilly, PE Bernard J. Heilstedt, PE Kenneth M. Briggs, PE William D. Stone, Sr George E. Vognild, PE William J. Accessibility and usability allow a person with anei physical disability to indepen- dently get to, enter and use a building or facility. This standard provides specifications for elements that are used in making functional spaces accessi- ble.
For example, it specifies technical require- ments for making doors, routes, seating, and other elements accessible. These accessible elements are used to design accessible wnsi spaces such as classrooms, hotel rooms, lobbies, or of- fices. This standard is for adoption by 199 agen- cies and by organizations setting model codes to achieve uniformity in the technical design criteria in building codes and other regulations.
This stan- dard is also used by non-governmental parties as technical design guidelines or requirements to make buildings and facilities accessible to and us- able by persons with physical disabilities.
Such requirements for application of this standard shall be specified by the adopting authority, including which and how many functional spaces and elements are to be made accessible within each building type, as de- scribed in 2. The administrative 1992 adopt- ing this standard shall specify the extent to which it is to cover remodeling, alteration, or rehabilitation within its jurisdiction.
Dimensions that are not marked “minimum,” “maximum,” or “nominal” are absolute, unless otherwise indicated in the text or captions. Millimeter equivalents for dimensions 3 in and larger have been rounded off to the nearest multiple of 5. An accessible pedestrian space be- tween elements, such as parking spaces, seating, and desks, that provides clearances appropriate for use of the elements.
anis Describes a site, building, facility, or portion thereof that complies with this standard and that can be approached, entered, and used by persons with physical disabilities. A path connecting all accessi- ble elements and spaces in a building or facility that is usable by persons with physical disabilities. The capability of certain building spaces and elements, such as kitchen counters, sinks, and grab bars, to be altered or added so as to accommodate the needs of a1177 with and without disabilities, or to accommodate the needs of persons with different types or degrees of dis- ability.
An accessible dwelling unit which has been designed for adaptability. A jurisdictional body that adopts or enforces regulations and standards for the design, construction, or operation of build- ings and facilities. Any slope opposing the running slope of a curb ramp or ramp. The slope of a pedestrian way that is perpendicular to the direction of travel see running slope.
A short ramp cutting through a curb or built up to it. Perceptible andi one or more of the senses. A continuous and unobstruct- ed way of travel from any point in a building or facil- ity to a public way. All or any portion of a building, structure, or area, including the site on which such building, structure, or area is located, wherein specific ser- vices are provided or activities are performed.
A crosswalk or other identified path intended for pedestrian use in crossing a ve- hicular way. Any building containing more than two dwelling units.

Describes an object that can be perceived using the sense of touch.
Accessible Elements and Spaces 4. The width for two wheelchairs to pass shall be 60 in mm minimum. The space re- quired for a wheelchair to make a degree turn shall be a clear space of 60 in mm diameter minimum or a T-shaped space within a 60 in 1 mm minimum square with arms 36 in mm wide minimum and 60 in mm long mini- mum. Wheelchair turning space shall be permitted to include knee and toe clear- ance in accordance with 4. The clear floor or ground space re- quired to accommodate a single, stationary wheel- chair and occupant shall be 30 in by 48 in mm by 1 mm minimum.
The minimum clear floor or ground space for wheelchairs shall be positioned for either forward or parallel approach to an object.
Knee clear- ance shall be 25 in mm in depth maximum, 30 in mm wide minimum, and 27 in mm high minimum. Toe clearance shall be 6 in mm deep maximum and 9 in mm high mini- mum. One full unobstructed side of the clear floor or ground space for a wheelchair shall adjoin or overlap an accessible route or ad- join another wheelchair clear floor space.
If a clear floor space is located in an alcove or otherwise confined on all or part of three sides, additional maneuvering clearances shall be provided as fol- lows: The width of an alcove shall be 36 in mm minimum when the depth exceeds 10 in mm.
The length of an alcove shall be 60 in mm minimum when the depth exceeds 10 in mm. Clear floor or ground spaces for wheelchairs shall com- ply with 4. If the clear floor space al- lows only forward approach to an object and is un- obstructed, the high forward reach permitted shall be 48 in mm maximum and the low forward reach shall be 15 in mm minimum above the floor.
If the high forward reach is over an obstruction, reach depth and heights shall comply with Table 4. If the clear floor space al- lows a parallel approach by a person in a wheel- chair, the high side reach permitted shall be 54 in mm maximum and the low side reach shall be 15 in mm minimum above the floor. If the side reach is over an ob- struction, the high reach shall be 46 in mm maximum providing: Accessible routes shall comply with 4.
Walking sur- faces with a slope not steeper than 1: Clear width of an accessible route shall be 36 in mm minimum, except at doors see 4. Clear width of the accessible route with turns around an obstruction less than 48 in mm wide shall have a clear space of 42 in by 48 in mm by mm minimum.
An accessible route with a clear width less than 60 in mm shall provide passing spaces at intervals of ft 61 m maxi- mum. These passing spaces shall be either a 60 in by 60 in mm by mm minimum space, or an intersection of two corridors or walks which provide a T-shaped turning space complying with 4.
