   No person shall occupy as owner, occupant or let to another for occupancy any dwelling or dwelling unit, for the purpose of living therein, which does not comply with the following requirements.
   (A)   Every habitable room shall have at least one window or skylight facing outdoors provided that if connected to a room or area used seasonally (e.g. porch) then adequate daylight must be possible through this inter-connection. The minimum total window or skylight area, measured between stops, for every habitable room shall be at least 10% of the floor area of the room but if light-obstruction structures are located less than three feet from the window and extend to a level above that of the ceiling of the room, the 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.
   (B)   (1)   Every habitable room shall have at least one window or skylight facing directly outdoors which can be opened easily, or such other device as will ventilate the room adequately, provided that is connected to a room or area used seasonally then adequate ventilation must be possible through this inter-connection. The total of openable window or skylight area in every habitable room shall be equal to at least 45% of the minimum window area size or minimum skylight type window size, as required herein, except where there is supplied some other device affording adequate ventilation and approved by the Health Officer.
      (2)   When facilities for interior climate control (heating, cooling and/or humidity) are integral functions of structures containing dwelling units or rooming units, the facilities shall be maintained and operated in a continuous manner and in accordance with the designed capacity of the installed equipment. During instances when the integral equipment is inoperative because of power or mechanical failure, alternative provisions for fresh air ventilation of each dwelling or rooming unit shall be provided.
   (C)   Every bathroom and water closet compartment, and non-habitable room used for food preparation, shall comply with the light and ventilation requirement for habitable rooms contained in this chapter, except that no window or skylight shall be required in such rooms if they are equipped with a ventilation system in working condition, which is approved by the Health Officer.
   (D)   (1)   Where there is usable electric service readily available from power lines which are not more than 300 feet away from a dwelling, every dwelling unit and all public and common areas shall be supplied with electric service, outlets and fixtures which shall be properly installed, shall be maintained in good and safe working condition, and shall be connected to a source of electric power in a manner prescribed by the ordinances, rules and regulations of Boone County or the rules and regulations of the city or town in which the dwelling unit is located.
      (2)   The minimum capacity of the services and the minimum number of outlets and fixtures shall be as follows:
         (a)   Every dwelling unit shall be supplied with at least one 15-ampere circuit and the circuit shall not be shared with another dwelling unit.
         (b)   Every habitable room shall contain at least two separate wall type duplex electric convenience outlets or one duplex convenience outlet and one supplied wall or ceiling type electric light fixture. No duplex outlet shall serve more than two fixtures or appliances.
         (c)   Temporary wiring or extension cords shall not be used as permanent wiring.
         (d)   Every non-habitable room, including water closet compartments, bathrooms, laundry rooms, furnace rooms and public halls shall contain at least one supplied ceiling or wall-type electric light fixture.
         (e)   All electric lights and outlets in bathrooms shall be controlled by switches which are of such design as shall minimize the danger of electric shock and the lights and outlets shall be installed and maintained so as to minimize the danger of electric shock.
         (f)   Every public hall and stairway in every multiple dwelling shall be adequately lighted by natural or artificial light at all times, so as to provide in all parts thereof at least six footcandles of light at the tread or floor level. Every public hall and stairway in structures containing not more than two 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.
