Where it is technically infeasible to comply with the new construction standards for any of these requirements for a change of group or occupancy, Items 1 through 6 shall conform to the requirements to the maximum extent technically feasible.
Exception: The accessible features listed in Items 1 through 6 are not required for an accessible route to Type B units.

These provisions shall apply to facilities designated as historic structures that undergo alterations or a change of occupancy, unless technically infeasible.
