A new requirement at section 229.1 of the 2010 Standards provides that if operable windows are provided for building users, then at least one window in an accessible space must be equipped with controls that comply with section 309.
Commenters generally supported this provision but some commenters asked whether the maximum five-pounds (5 lbs.) of force requirement of section 309 applies to the window latch itself or only to the force required to open the window. Section 309 applies to all controls and operating mechanisms, so the latch must comply with the requirement to operate with no more than five pounds of force (5 lbf).
229.1 General. Where glazed openings are provided in accessible rooms or spaces for operation by occupants, at least one opening shall comply with 309. Each glazed opening required by an administrative authority to be operable shall comply with 309.
1. Glazed openings in residential dwelling units required to comply with 809 shall not be required to comply with 229.
2. Glazed openings in guest rooms required to provide communication features and in guest rooms required to comply with 206.5.3 shall not be required to comply with 229.
