codes


Accessible operable windows are required by all three national building codes — BOCA, SBCCI, and the UBC as well as the current draft of the upcoming IBC. Prior to 1998 included were those operable windows, within accessible spaces, required by Code for ventilation and also those required for emergency escape and rescue. All codes after 1998 additionally require that, if operable windows are provided in an accessible space, no less than one in each room shall be accessible. All Building Codes reference the ANSI A117.1 for technical accessibility technical requirements. Some states, such as California and Washington have created their own requirements for accessible operable windows. The federal government¹s Access Board, with support from the DOJ, also require accessible windows through the ABA, the ADAAG and the UFAS.
