Provided any local regulations approved by the local governing body which are found by the Council to be more stringent than the adopted statewide fire prevention code and which are found to regulate only activities and conditions in buildings, structures, and premises that pose dangers of fire, explosion or related hazards, and are not matters in conflict with the State Building Code, may be approved. Local governments may enforce the fire prevention code of the State Building Code using civil remedies authorized under G.S. 143-139, 153A-123, and 160A-175. If the Commissioner of Insurance or other State official with responsibility for enforcement of the Code institutes a civil action pursuant to G.S. 143-139, a local government may not institute a civil action under G.S. 143-139, 153A-123, or 160A-175 based upon the same violation. Appeals from the assessment or imposition of such civil remedies shall be as provided in G.S. 160D-1127.
A local government may not adopt any ordinance in conflict with the exemption provided by subsection (c1) of this section. No local ordinance or regulation shall be construed to limit the exemption provided by subsection (c1) of this section.

(j) Areas of Refuge Required. - Class III buildings shall be provided with a designated "area of refuge" at the 250 ft. level and on at least every eighth floor or fraction thereof above that level to be designed so that occupants above the 250 ft. level can enter at all times and be safely accommodated in floor areas meeting the following requirements unless the building is completely sprinklered:
(1) Identification and Size. - These areas of refuge shall be identified on the plans and in the building as necessary. The area of refuge shall provide not less than 3 sq. ft. per occupant for the total number of occupants served by the area based on the occupancy content calculated by Section 1105. A minimum of two percent (2%) of the number of occupants on each floor shall be assumed to be handicapped and no less than 16 sq. ft. per handicapped occupant shall be provided. Smoke proof stairways meeting the requirements of Section 1104.2 and pressurized stairways meeting the requirements of Section 1108.3(e)(2) may be used for ambulatory occupants at the rate of 3 sq. ft. of area of treads and landings per person, but in no case shall the stairs count for more than one-third of the total occupants. Doors leading to designated areas of refuge from stairways or other areas of the building shall not have locking hardware or shall be automatically unlocked upon receipt of any manual or automatic fire alarm signal.
(2) Pressurized. - The area of refuge shall be pressurized with 100% fresh air utilizing the maximum capacity of existing mechanical building air conditioning system without recirculation from other areas or other acceptable means of providing fresh air into the area.
(3) Fire Resistive Separation. - Walls, partitions, floor assemblies and roof assemblies separating the area of refuge from the remainder of the building shall be noncombustible and have a fire resistance rating of not less than one hour. Duct penetrations shall be protected as required for penetrations of shafts. Metallic piping and metallic conduit may penetrate or pass through the separation only if the openings around the piping or conduit are sealed on each side of the penetrations with impervious noncombustible materials to prevent the transfer of smoke or combustion gases from one side of the separation to the other. The fire door serving as a horizontal exit between compartments shall be so installed, fitted and gasketed to provide a barrier to the passage of smoke.
(4) Access Corridors. - Any corridor leading to each designated area of refuge shall be protected as required by Sections 1104 and 702. The capacity of an access corridor leading to an area of refuge shall be based on 150 persons per unit width as defined in Section 1105.2. An access corridor may not be less than 44 inches in width. The width shall be determined by the occupant content of the most densely populated floor served. Corridors with one-hour fire resistive separation may be utilized for area of refuge at the rate of three sq. ft. per ambulatory occupant provided a minimum of one cubic ft. per minute of outside air per square foot of floor area is introduced by the air conditioning system.
(5) Penetrations. - The continuity of the fire resistance at the juncture of exterior walls and floors must be maintained.
(k) Smoke Venting. - Smoke venting shall be accomplished by one of the following methods in nonsprinklered buildings:
(1) In a nonsprinklered building, the heating, ventilating and air conditioning system shall be arranged to exhaust the floor of alarm origin at its maximum exhausting capacity without recirculating air from the floor of alarm origin to any other floor. The system may be arranged to accomplish this either automatically or manually. If the air conditioning system is also used to pressurize the areas of refuge, this function shall not be compromised by using the system for smoke removal.
(2) Venting facilities shall be provided at the rate of 20 square feet per 100 lineal feet or 10 square feet per 50 lineal feet of exterior wall in each story and distributed around the perimeter at not more than 50 or 100 foot intervals openable from within the fire floor.
