General. The purpose of this code is to ensure that barrier- free design is incorporated in all buildings, facilities, site work and other improvements to which this code applies in compliance with state law to ensure that these improve- ments are accessible to and usable by persons with disabili- ties. Additions, alterations and structural repairs in all buildings and facilities shall comply with these provisions for new buildings, except as otherwise provided and speci- fied herein.

The provisions of these regulations shall apply to any por- table buildings leased or owned by a school district, and shall also apply to temporary and emergency buildings and facili- ties. Temporary buildings and facilities are not of permanent construction but are extensively used or are essential for pub- lic use for a period of time. Examples of temporary buildings or facilities covered include, but are not limited to: reviewing stands, temporary classrooms, bleacher areas, exhibit areas, temporary banking facilities, temporary health screening ser- vices or temporary safe pedestrian passageways around a construction site.

In addition, to incorporate standards at least as restrictive as those required by the federal government for barrier-free design under (1) Title III (Public Accommodations and Com- mercial Facilities), Subpart D (New Construction and Alter- ation) (see 28 C.F.R., Part 36), and (2) Title II (Public Entities), Section 35.151 (New Construction and Alterations) (see 28 C.F.R., Part 35) both from the Americans with Dis- abilities Act of 1990, 2004 Americans with Disabilities Act Accessibility Guidelines, as adopted by the U.S. Department of Justice (see 36 C.F.R. Part 1191, Appendices B and D), and (3) under the Fair Housing Amendments Act of 1988.
