§ 70.251 MINIMUM STANDARDS FOR LIGHT, VENTILATION AND HEATING
   (A)   Every habitable room shall have at least one (1) window or skylight facing directly to the outdoors. The minimum total window area, measured between stops, for every habitable room shall be ten (10%) percent of the floor area of the room. Whenever walls or other portions of structures face a window of any the room, and such light-obstructing structures are located less than three (3) feet from the window and extend to a level above that of the ceiling of the room, such a window shall not be deemed to face directly to the outdoors and shall not be included as contributing to the required minimum total window area. Whenever the only window in a room is a skylight type window in the top of the room, the total window area of the skylight shall equal at least fifteen (15%) percent of the total floor area of the room.
   (B)   Every habitable room shall have at least one (1) window or skylight which can easily be opened, or such other device as will adequately ventilate the room. The total of openable window area in every habitable room shall be equal to at least forty-five (45%) percent of the minimum window area size or minimum skylight-type window size, as required in this chapter, except where there is supplied some other device affording adequate ventilation and approved by the building official.
   (C)   Every bathroom and water closet compartment shall comply with the light and ventilation requirements for habitable rooms contained in subsections (A) and (B) above, except that no window or skylight shall be required where the bathrooms and water closet compartments are equipped with a ventilation system which provides ventilation equivalent to that in (B) above.
   (D)   Where there is electric service available from power lines, which are not more than three hundred (300) feet away from a dwelling, every habitable room of the dwelling shall contain at least two (2) separate floor or wall-type electric convenience outlets, or one (1) convenience outlet and one (1) supplied ceiling-type electric light fixture; and every water closet compartment, bathroom, laundry room, furnace room, and public hall shall contain at least one (1) supplied ceiling or wall-type electric light fixture. Every such outlet and fixture shall be properly installed, shall be maintained in good and safe working condition, and shall be connected to the source of electric power in a safe manner.
   (E)   Every public hall and stairway in every multiple dwelling containing five (5) or more dwelling units, shall be adequately lighted at all times. Every public hall and stairway in structures devoted solely to dwelling occupancy and containing not more than four (4) dwelling units, may be supplied with conveniently located light switches, controlling an adequate lighting system which may be turned on when needed, instead of full-time lighting.
   (F)   Every dwelling shall have heating facilities which are installed and maintained in accordance with the Kentucky Standards of Safety, and are capable of safely and adequately heating all habitable rooms, bathrooms, and water closet compartments in every dwelling unit located therein to a temperature of at least seventy (70) degrees Fahrenheit, at a distance three (3) feet above floor level, when the outside temperature is zero degrees Fahrenheit. Fuel-burning space heaters located in sleeping rooms or rooms generally kept closed, shall be connected to a suitable chimney, flue or gas vent. There shall be provided an adequate air supply for combustion through one (1) or more openings to the exterior, or by means of fixed openings to interior spaces which open to the exterior.
   (G)   From May 15 to October 15 every door opening directly from a dwelling unit to outdoor space shall have supplied screens and a self-closing device; every window or other device with openings to outdoor space, used or intended to be used for ventilation shall likewise be supplied with screens; provided that the screens shall not be required during the period in rooms deemed by the building official to be located high enough in the upper stories of buildings as to be free from the insects.
   (H)   Every basement or cellar window used or intended to be used for ventilation, and every other opening to a basement which might provide an entry for rodents, shall be supplied with a screen or the other devices as will effectively prevent their entrance.
