(1) Each facility or part of a facility constructed by, on behalf of, or for the use of a public entity shall be designed and constructed in such manner that the facility or part of the facility is readily accessible to and usable by individuals with disabilities, if the construction was commenced after January 26, 1992. (2) Exception for structural impracticability. (i) Full compliance with the requirements of this section is not required where a public entity can demonstrate that it is structurally impracticable to meet the requirements. Full compliance will be considered structurally impracticable only in those rare circumstances when the unique characteristics of terrain prevent the incorporation of accessibility features. (ii) If full compliance with this section would be structurally impracticable, compliance with this section is required to the extent that it is not structurally impracticable. In that case, any portion of the facility that can be made accessible shall be made accessible to the extent that it is not structurally impracticable. (iii) If providing accessibility in conformance with this section to individuals with certain disabilities (e.g., those who use wheelchairs) would be structurally impracticable, accessibility shall nonetheless be ensured to persons with other types of disabilities, (e.g., those who use crutches or who have sight, hearing, or mental impairments) in accordance with this section. |
| double vanity sink drain plumbing diagram: Fair Housing Act Design Manual U.S. Department of Housing and Urban Development, United States. Department of Housing and Urban Development. Office of Housing, 2005 The Fair Housing Act Design Manual: A Manual to Assist Designers and Builders in Meeting the Accessibility Requirements of The Fair Housing Act provides clear and helpful guidance about ways to design and construct housing which complies with the Fair Housing Act. The manual provides direct information about the accessibility requirements of the Act, which must be incorporated into the design, and construction of multifamily housing covered by the Act. It carries out two statutory responsibilities: (1) to provide clear statement of HUD's interpretation of the accessibility requirements of the Act so that readers may know what actions on their part will provide them with a safe harbor; and (2) to provide guidance in the form of recommendations which, although not binding meet the Department's obligation to provide technical assistance on alternative accessibility approaches which will comply with the Act, but may exceed its minimal requirements. The latter information allows housing providers to choose among alternative and also provides persons with disabilities with information on accessible design approaches. The Manual clarifies what are requirements under the Act and what are HUD's technical assistance recommendations. The portions describing the requirements are clearly differentiated from the technical assistance recommendations. |
| double vanity sink drain plumbing diagram: Architects' Data Ernst Neufert, Peter Neufert, 1991-01-15 This is an essential aid in the initial design and planning of a project. The relevant building type is located by a comprehensive index and cross reference system, a condensed commentary covers user requireements, planning criteria, basic dimensions and other considerations of function, siting aspect etc. A system of references based on an extensive bibliography supports the text. In every section plans, sections, site layouts, design details and graphs illustrated key aspects of a building type's design. Most illustrations are dimensioned or scaled - the metric system of measurement is used throughout, and the equivalent in feet/inches can easily be read either off a graphic scale on the page or from the built-in conversion table. The illustrations are international in origin and include both well know and less famous designers. Architects Data is primarily a handbook of building types rather than of construction techniques and details. However its treatment of components (such as doors and windows) and of spaces for building services is extremely thorough, since consideration of this data is an essential element of the planning process. The opening pages of basic data on man and his buildings cover critical subjects such as scale, drawing practice, noise, light and space for the same reason. Particular attention has also been paid to the implications of energy conservation, means of escape from fire and the needs of the elderly and the disabled. |
