6.12.302: LIGHT, VENTILATION AND HEATING:
It shall be unlawful for any person to occupy as owner-occupant or to lease to another for occupancy any dwelling or dwelling unit which does not comply with the following requirements:
   A.   Lighting Of Habitable Rooms: Every habitable room in a dwelling or dwelling unit shall either have at least one window or skylight facing directly to the outside, or shall receive from adjoining rooms an equivalent amount of light, which shall provide illumination equivalent to forty (40) watts.
   B.   Ventilation: Every habitable room shall have at least one window or skylight which can be opened, or other device as will adequately ventilate the room.
   C.   Bathrooms And Water Closets: Every bathroom and water closet compartment shall be in compliance with the light and ventilation requirements for habitable rooms contained in subsections A and B of this section, except that no window or skylight shall be required in adequately ventilated bathrooms and water closet compartments equipped with a ventilation system which is approved by the Administrator and capable of four (4) air changes per hour.
   D.   Outlets And Fixtures: Where there is electric service available from power lines which are not more than three hundred feet (300') away from a dwelling, every habitable room of the dwelling shall contain at least two (2) separate wall type electric receptacle outlets, or one receptacle outlet and one supplied ceiling type electric light fixture; and every water closet compartment, bathroom, laundry room, furnace room and public hall shall contain at least one supplied ceiling or wall type electric light fixture. Every 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 in accord with the National Electrical Code.
   E.   Heating Facilities: Every dwelling shall have heating facilities which are properly installed, are maintained in good and safe working condition, and are capable of safely and adequately heating all habitable rooms, bathrooms and water closet compartments in every dwelling unit within the dwelling to a temperature of at least seventy degrees Fahrenheit (70°F), at a distance three feet (3') above floor level at the approximate center of the room, during winter months. Space heaters may not be used as a permanent, general heating facility; but may only be used as a temporary emergency measure.
   F.   Public Halls And Stairways: 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. Common areas need to be lighted at all times with a minimum sixty (60) watt bulb for every two hundred (200) square feet of floor area, provided that the spacing between lights shall not be greater than thirty feet (30'). Exterior stairways require a minimum of forty (40) watts at floors, landings and treads. Natural or artificial light is required in all other spaces including basements, laundry and storage areas. The light provided should allow for safe occupancy of the space. Older properties constructed in accord with building codes which did not require the installation of light sources in common areas shall nevertheless provide for safe ingress and egress with reasonable and adequate lighting.
   G.   Screens: Each window with openings to outdoor space which is used or intended to be used for ventilation shall be supplied with a screen.
   H.   Screens For Openings To Basements And Cellars: 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 other devices as will effectively prevent their entrance.
   I.   Exterior Lighting: All exterior lighting for single, two- family and multi-family residential shall be arranged to reflect away from any adjoining premises and any public right of way, and shall be shielded to contain all direct rays on the site.
