(A) Buildings used for institutional occupancies such as convalescent homes, homes for the aged or children or the handicapped, nurseries, nursing homes or sanitariums or sanatoriums shall not exceed one story in height, nor more than 2,500 square feet in area, when constructed of non-fire-resistive materials. Existing wood frame buildings converted to those occupancies may be exempt from those restrictions if equipped with a sprinkling system, with fire-resistant walls and ceilings, and with other fire and safety measures applicable to the case, and all approved by the Building Commissioner. In no case shall the building for such purpose exceed two stories in height.
(B) In any institutional building which is two stories in height, the interior access or accesses between the first and second floors shall be enclosed fire-resistant stair wells, provided with a swinging/ self-closing, close-fitting, fire-resistant door to prevent passage of flame, heat, gas and smoke. Each story shall also be provided with two or more separate means of entrance and exit, one of which is exterior to the building, and with doors opening outward.
(C) Basement or attic work or store rooms under or over an institutional occupancy shall be separated from such occupancy by not less than one-hour fire-resistant construction and be tight to prevent passage of flame, heat, gas and smoke. Boiler and furnace rooms in such an occupancy shall be as set forth in § 150.066 of this chapter.
(D) Any new institutional occupancy building shall be of fire-resistant construction throughout, designed by a licensed architect and approved by the National Board of Fire Underwriters and by the Building Commissioner.
