IntroductionOn July 23, 2004 the U.S. Access Board published new design guidelines that coveraccess for people with disabilities under the Americans with Disabilities Act (ADA).These guidelines update access requirements for a wide range of facilities in the publicand private sectors covered by the law. They also include updated guidelines forFederal facilities covered by the Architectural Barriers Act (ABA). Both the ADAguidelines and the ABA guidelines, which the Board updated jointly to make them moreconsistent, address access in new construction and alterations and contain scopingprovisions, which indicate what has to comply, and technical specifications, which spellout how compliance is to be achieved.This new design document is the culmination of a comprehensive, decade-long reviewand update of the Board’s ADA Accessibility Guidelines, which were first published in1991. Revisions have been made so that the guidelines continue to meet the needs ofpeople with disabilities and keep pace with technological innovations. For example,new provisions for ATMs specify audible output so that people with vision impairmentsare provided equal access, and reach ranges have been lowered to better serve peoplewho use wheelchairs and persons of short stature. The guidelines also feature a newformat and organization and have been extensively edited for greater clarity.As part of this update, the Board has made its guidelines more consistent with modelbuilding codes, such as the International Building Code (IBC), and industry standards.It coordinated extensively with model code groups and standard-setting bodiesthroughout the process so that differences could be reconciled. As a result, a historiclevel of harmonization has been achieved which has brought about improvements to theguidelines as well as to counterpart provisions in the IBC and key industry standards,including those for accessible facilities issued through the American National StandardsInstitute (ANSI). The Board believes that this achievement will greatly facilitatecompliance.The Board’s guidelines serve as the baseline for standards used to enforce the ADAand the ABA. These standards, which are maintained by other Federal agencies, suchas the U.S. Department of Justice under the ADA, will be updated according to the newguidelines. It is these standards, not the Board’s guidelines, which the public mustfollow.
Answers to Common Questions About the New ADA-ABA GuidelinesHow were the guidelines developed?The Board organized an advisory committee to review the original guidelines and torecommend changes in order to get input from a cross section of stakeholders at theoutset of the process. The ADAAG Review Advisory Committee, which includedrepresentation from the design and construction industry, the building code community,and people with disabilities, among others, submitted a report to the Board that detailedrecommended revisions to the substance, organization, and format of the guidelines.The finalized guidelines are based largely on these recommendations. The Boardpublished the guidelines in proposed form in November, 1999 and made them availablefor public comment for six months. The Board received over 2,500 public comments onits proposal and finalized the guidelines based on this input.Should the new guidelines be followed at this time?No. The Board’s guidelines are not mandatory on the public. They serve as thebaseline for enforceable standards maintained by other Federal agencies. In thisrespect, they are similar to a model building code in that they are not required to befollowed except as adopted by an enforcing authority. Under the ADA, the Departmentof Justice (DOJ) (and in the case of transit facilities, the Department of Transportation(DOT)) is responsible for enforceable standards based on the Board’s guidelines.These agencies will update their ADA standards based on the new guidelines. In doingso, they will indicate when the new standards are to be followed. Several otheragencies (the General Services Administration, Department of Defense, Department ofHousing and Urban Development, and the U.S. Postal Service) hold a similarresponsibility for standards under the ABA.“Guidelines” “Standards” what’s the difference?Guidelines versus standards it’s an important distinction under the ADA and ABA.Guidelines are issued by the Board, standards by designated agencies such as DOJand DOT. Standards are what the public must follow to comply with the laws; theguidelines are what these agencies must follow in setting or updating their standards.When the Board issues guidelines, it does not change compliance for the public until thestandards are similarly changed and an effective date set.What standards should be followed at this time under the ADA the ABA?The existing standards are to be followed until the effective date of the updatedstandards. ADA standards issued by DOJ and DOT in 1991 based on the Board’soriginal ADA Accessibility Guidelines (ADAAG) remain the standards to follow at thistime. (DOJ’s regulations permit state and local governments the option of using anearlier standard known as the Uniform Federal Accessibility Standards (UFAS) as analternative.) Under the ABA, UFAS remains the applicable standard until itsreplacement by new standards based on the Board’s updated guidelines (some Federalagencies have a policy of applying ADAAG in addition to UFAS).
For public accommodations and commercial facilities subject to title III of theADA, the enforceable standards are the ADA Standards for Accessible Designoriginally published by the Department of Justice on July 26, 1991 (28 CFR Part36, Appendix A) www.ada.gov/stdspdf.htm Facilities subject to title II of the ADA may elect to use one of two standards; theUniform Federal Accessibility Standards (UFAS) or, the ADA Standards forAccessible Design (above). Transportation Facilities, subject to titles II and III must comply with theDepartment of Transportation Standards for Accessible Design (49 CFR Part 37,Appendix A) www.fta.dot.gov/legal/regulations/us dot/5598 ENG HTML.htm Facilities subject to the Architectural Barriers Act must comply with the UniformFederal Accessibility Standards (UFAS) www.access-board.gov/ufas/ufashtml/ufas.htmWhen will the standards be updated?DOJ and DOT will issue notices on the update of their ADA standards that will providean opportunity for public comment. In doing so, these agencies will address applicationissues, such as how much lead time to allow in setting an effective date for the newstandards. Gauging the turn-around time for this process, which may vary by agency, isoften difficult due to the regulatory steps involved. Under the ABA, standard-settingagencies will follow a similar public comment process or an administrative process inupdating their ABA standards. The Board will provide updates on the progress made bythe ADA and ABA standard-setting agencies through its newsletter, e-mail updates, andits website.Where can I get further assistance on the new guidelines?Accessibility specialists at the Access Board are available to assist you by providingguidance on the use of the ADA and ABA Accessibility Guidelines.

AMERICANS WITH DISABILITIES ACT: SCOPINGADA CHAPTER 1: APPLICATION AND ADMINISTRATIONADA CHAPTER 1: APPLICATION AND ADMINISTRATION101 Purpose101.1 General. This document contains scoping and technical requirements for accessibility to sites,facilities, buildings, and elements by individuals with disabilities. The requirements are to be appliedduring the design, construction, additions to, and alteration of sites, facilities, buildings, and elements tothe extent required by regulations issued by Federal agencies under the Americans with Disabilities Actof 1990 (ADA).Advisory 101.1 General. In addition to these requirements, covered entities must complywith the regulations issued by the Department of Justice and the Department ofTransportation under the Americans with Disabilities Act. There are issues affectingindividuals with disabilities which are not addressed by these requirements, but which arecovered by the Department of Justice and the Department of Transportation regulations.101.2 Effect on Removal of Barriers in Existing Facilities. This document does not address existingfacilities unless altered at the discretion of a covered entity. The Department of Justice has authorityover existing facilities that are subject to the requirement for removal of barriers under title III of the ADA.Any determination that this document applies to existing facilities subject to the barrier removalrequirement is solely within the discretion of the Department of Justice and is effective only to the extentrequired by regulations issued by the Department of Justice.102 Dimensions for Adults and ChildrenThe technical requirements are based on adult dimensions and anthropometrics. In addition, thisdocument includes technical requirements based on children’s dimensions and anthropometrics fordrinking fountains, water closets, toilet compartments, lavatories and sinks, dining surfaces, and worksurfaces.103 Equivalent FacilitationNothing in these requirements prevents the use of designs, products, or technologies as alternatives tothose prescribed, provided they result in substantially equivalent or greater accessibility and usability.Advisory 103 Equivalent Facilitation. The responsibility for demonstrating equivalentfacilitation in the event of a challenge rests with the covered entity. With the exception oftransit facilities, which are covered by regulations issued by the Department ofTransportation, there is no process for certifying that an alternative design providesequivalent facilitation.104 Conventions104.1 Dimensions. Dimensions that are not stated as “maximum” or “minimum” are absolute.5
ADA CHAPTER 1: APPLICATION AND ADMINISTRATIONAMERICANS WITH DISABILITIES ACT: SCOPING104.1.1 Construction and Manufacturing Tolerances. All dimensions are subject to conventionalindustry tolerances except where the requirement is stated as a range with specific minimum andmaximum end points.Advisory 104.1.1 Construction and Manufacturing Tolerances. Conventional industrytolerances recognized by this provision include those for field conditions and those that maybe a necessary consequence of a particular manufacturing process. Recognized tolerancesare not intended to apply to design work.It is good practice when specifying dimensions to avoid specifying a tolerance wheredimensions are absolute. For example, if this document requires “1½ inches,” avoidspecifying “1½ inches plus or minus X inches.”Where the requirement states a specified range, such as in Section 609.4 where grab barsmust be installed between 33 inches and 36 inches above the floor, the range provides anadequate tolerance and therefore no tolerance outside of the range at either end point ispermitted.Where a requirement is a minimum or a maximum dimension that does not have twospecific minimum and maximum end points, tolerances may apply. Where an element is tobe installed at the minimum or maximum permitted dimension, such as “15 inches minimum”or “5 pounds maximum”, it would not be good practice to specify “5 pounds (plus X pounds)or 15 inches (minus X inches).” Rather, it would be good practice to specify a dimensionless than the required maximum (or more than the required minimum) by the amount of theexpected field or manufacturing tolerance and not to state any tolerance in conjunction withthe specified dimension.Specifying dimensions in design in the manner described above will better ensure thatfacilities and elements accomplish the level of accessibility intended by these requirements.It will also more often produce an end result of strict and literal compliance with the statedrequirements and eliminate enforcement difficulties and issues that might otherwise arise.Information on specific tolerances may be available from industry or trade organizations,code groups and building officials, and published references.104.2 Calculation of Percentages. Where the required number of elements or facilities to be providedis determined by calculations of ratios or percentages and remainders or fractions result, the nextgreater whole number of such elements or facilities shall be provided. Where the determination of therequired size or dimension of an element or facility involves ratios or percentages, rounding down forvalues less than one half shall be permitted.104.3 Figures. Unless specifically stated otherwise, figures are provided for informational purposesonly.6

AMERICANS WITH DISABILITIES ACT: SCOPINGADA CHAPTER 1: APPLICATION AND ADMINISTRATIONASME A18.1-2003 Safety Standard for Platform Lifts and Stairway Chairlifts, (see 410.1).Advisory 105.2.2 ASME. ASME A17.1-2000 is used by local jurisdictions throughout theUnited States for the design, construction, installation, operation, inspection, testing,maintenance, alteration, and repair of elevators and escalators. The majority of therequirements apply to the operational machinery not seen or used by elevator passengers.ASME A17.1 requires a two-way means of emergency communications in passengerelevators. This means of communication must connect with emergency or authorizedpersonnel and not an automated answering system. The communication system must bepush button activated. The activation button must be permanently identified with the word“HELP.” A visual indication acknowledging the establishment of a communications link toauthorized personnel must be provided. The visual indication must remain on until the callis terminated by authorized personnel. The building location, the elevator car number, andthe need for assistance must be provided to authorized personnel answering the emergencycall. The use of a handset by the communications system is prohibited. Only the authorizedpersonnel answering the call can terminate the call. Operating instructions for thecommunications system must be provided in the elevator car.The provisions for escalators require that at least two flat steps be provided at the entranceand exit of every escalator and that steps on escalators be demarcated by yellow lines 2inches wide maximum along the back and sides of steps.ASME A18.1-1999 and ASME A18.1-2003 address the design, construction, installation,operation, inspection, testing, maintenance and repair of lifts that are intended fortransportation of persons with disabilities. Lifts are classified as: vertical platform lifts,inclined platform lifts, inclined stairway chairlifts, private residence vertical platform lifts,private residence inclined platform lifts, and private residence inclined stairway chairlifts.This document does not permit the use of inclined stairway chairlifts which do not provideplatforms because such lifts require the user to transfer to a seat.ASME A18.1 contains requirements for runways, which are the spaces in which platforms orseats move. The standard includes additional provisions for runway enclosures, electricalequipment and wiring, structural support, headroom clearance (which is 80 inchesminimum), lower level access ramps and pits. The enclosure walls not used for entry or exitare required to have a grab bar the full length of the wall on platform lifts. Access ramps arerequired to meet requirements similar to those for ramps in Chapter 4 of this document.Each of the lift types addressed in ASME A18.1 must meet requirements for capacity, load,speed, travel, operating devices, and control equipment. The maximum permitted height foroperable parts is consistent with Section 308 of this document. The standard alsoaddresses attendant operation. However, Section 410.1 of this document does not permitattendant operation.105.2.3 ASTM.

ASTM F 1292-99 and ASTM F 1292-04 establish a uniformmeans to measure and compare characteristics of surfacing materials to determine whethermaterials provide a safe surface under and around playground equipment. These standardsare referenced in the play areas requirements of this document when an accessible surfaceis required inside a play area use zone where a fall attenuating surface is also required. Thestandards cover the minimum impact attenuation requirements, when tested in accordancewith Test Method F 355, for surface systems to be used under and around any piece ofplayground equipment from which a person may fall.ASTM F 1487-01 establishes a nationally recognized safety standard for public playgroundequipment to address injuries identified by the U.S. Consumer Product Safety Commission.It defines the use zone, which is the ground area beneath and immediately adjacent to aplay structure or play equipment designed for unrestricted circulation around the equipmentand on whose surface it is predicted that a user would land when falling from or exiting aplay structure or equipment. The play areas requirements in this document reference theASTM F 1487 standard when defining accessible routes that overlap use zones requiringfall attenuating surfaces. If the use zone of a playground is not entirely surfaced with anaccessible material, at least one accessible route within the use zone must be provided fromthe perimeter to all accessible play structures or components within the playground.ASTM F 1951-99 establishes a uniform means to measure the characteristics of surfacesystems in order to provide performance specifications to select materials for use as anaccessible surface under and around playground equipment. Surface materials that complywith this standard and are located in the use zone must also comply with ASTM F 1292.The test methods in this standard address access for children and adults who may traversethe surfacing to aid children who are playing. When a surface is tested it must have anaverage work per foot value for straight propulsion and for turning less than the averagework per foot values for straight propulsion and for turning, respectively, on a hard, smoothsurface with a grade of 7% (1:14).105.2.4 ICC/IBC.
