1207.2

Occupiable spaces, habitable spaces and corridors shall have a ceiling height of not less than 7’-6” above the finished floor. Bathrooms, toilet rooms, kitchens, storage rooms and laundry rooms shall have a ceiling height of not less than 7 feet above the finished floor.

Requesting lower than 7’-6” ceilings in the basement unit.

We are proposing a 6’-9 1/4” ceiling height in the basement, and adding two 34” x 48” casement egress windows in the bedrooms. The existing head height to the bottom of floor framing is currently 6’-10” and will be reduced to 6’-9 1/4” with the addition of (1) layer ½” type X gypsum board adhered to ¼” resilient channels at the underside of floor framing. This assembly will be based on GA File No. FC 5120.

There is one section in the basement along the egress path where the existing 6x8 beam will be raised up into the ceiling and the existing joists at those locations will be hung from the beam. The existing furnace in the basement is to be removed as all the units will be utilizing ductless mini-splits for heating and cooling purposes. This will eliminate any duct runs in the basement that would have reduced the head height.

703.2

Fire-resistance ratings. The fire-resistance rating of building elements components or assemblies shall be determined in accordance with the test procedures set forth in ASTM E 119 or UL 263 or in accordance with Section 703.3.

We are proposing to keep the existing 2x8 floor joist framing.

We are proposing to keep the existing 2x8 floor joists in lieu of using 2x10s to meet the fire rating requirements of GA File No. FC 5120, as well as the STC rating. The assembly occurs at the basement ceiling/main level floor.

The building was built per residential code with 2x8 joists at 16” O.C. and will continue to operate nearly identical to its original use. We are proposing to convert this property from single family (R3) to transient living for short term rental with 10 or fewer occupants per unit (R3). The building is equipped with an approved NFPA 13D sprinkler system installed on each level with an alarm system. It would cause an undue burden to change the floor framing to 2x10 in order to achieve a 1-hr rated assembly that would also decrease the head height of the space.
