J: ACCESSIBLE BUILDINGS -- HISTORIC PRESERVATION
Alterations to a qualified historic building or facility must comply with the minimum
requirements for alterations in 4.1.6. Use the applicable survey forms for new
construction for each altered element or space.
If it is determined, in accordance with the required procedures in 4.1.7(2), that the
proposed alterations would threaten or destroy the historic significance of the building
or facility, the following alternative requirements in 4.1.7(3) may be utilized:
- Site Accessible Route - Minimum Number: At least one accessible route
complying with 4.3 must be provided from a site access point to an accessible entrance.
- Ramps - Slope and Rise: A ramp with a slope no steeper than 1:6 may be
used as part of an accessible route to an entrance but the run must not exceed 2 feet.
- Entrances - Minimum Number and Primary Entrance: At least one
accessible entrance complying with 4.14 and which is used by the public must be provided.
If no public entrance can be made accessible, then access may be provided at any entrance
which is open (unlocked) when directional signage is provided at the primary public
entrance. The alternative accessible entrance must have a notification system, and where
security is a concern, remote monitoring may be used. Building Accessible Route - Access
to Other Floors: Accessible routes from an accessible entrance to all publicly used spaces
must be provided at least on the accessible entrance level. Access must be provided in
compliance with 4.1 to all levels of a building and facility whenever practicable.
- Toilet Rooms - Unisex: If toilets are provided, then at least one
toilet facility, which may be unisex in design, complying with 4.22 and 4.1.6, must be
provided on an accessible route.
- Displays: Displays and written information should be located so as to be seen by a seated person.
If it is determined, in accordance with the required procedures in 4.1.7(2), that it is
not feasible to provide physical access to a qualified historic building or facility using
the alternative requirements in 4.1.7(3) without threatening or destroying the historic
significance of the building or facility, alternative methods of access must be provided.
