§ 151.016 LIGHT, VENTILATION, AND HEAT.
   No person shall occupy as owner/occupant, or let to another for occupancy, any dwelling or dwelling units for the purposes of living therein, which does not comply with the following requirements:
   (A)   Emergency exit. Every habitable room used for sleeping purposes shall have at least one openable window, second door, or other opening facing directly to the outdoors or leading directly to a room that has an opening directly outdoors. The minimum openable area of the window or other area shall be sufficient in size to allow for emergency egress, it being the intent of this provision to ensure that there are two means of escape from all habitable rooms used for sleeping. The window or other opening shall have a minimum net clear openable width of 20 inches, a minimum net clear openable height of 24 inches, and the finished sill height shall not be more than 44 inches above the floor. The minimum total area shall not be less than 5.7 square feet. Escape windows or other openings with finished sill heights below the adjacent ground level shall have a window well that is at least as deep as the window sill, extends at least 36 inches from the building, and allows the opening of the window to a full 90 degrees.
   (B)   Ventilation. Every habitable room shall have at least one window or skylight which can easily be opened or such other means to adequately ventilate the room as approved by the city. Whenever the only window in a room is a skylight-type window in the top of such room, the total window area of such skylight shall equal at least 15% of the total floor area of such room.
   (C)   Bathroom light and ventilation. Every bathroom and water closet compartment shall comply with the light and ventilation requirements for habitable rooms contained in this section except that no window or skylight shall be required in adequately ventilated bathrooms and water closet compartments equipped with ventilation.
   (D)   Electric outlets. Where there is electric service available from power lines which are not more than 300 feet away from a dwelling, every habitable room of such dwelling shall contain at least two separate floor or wall-type electric convenience outlets or one such convenience 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 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. Every dwelling unit must have access to the fuse or circuit boxes serving that unit for safety purposes. Kitchen, bath and u-1 occupancies must be protected by G.F.I. outlets.
   (E)   Heating facilities. Every dwelling shall have heating facilities which are properly installed, are maintained in safe and good working condition, 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 70°F, at a distance of three feet above floor level, under ordinary minimum winter conditions. Every dwelling unit must have access at all times to the heating thermostat controls for its heating supply.
   (F)   Lighting halls and stairways. Every hallway and stairway in every multiple dwelling containing five or more dwelling units shall be adequately lighted at all times. Every hallway and stairway in structures devoted solely to dwelling occupancy and containing not more than four 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.
   (G)   Screens. During that portion of each year when it is necessary for protection against mosquitoes, flies, and other insects, every door opening directly from a dwelling unit to outdoor space shall have supplied screens and a self-closing device, and every window opening from a dwelling unit required for ventilation shall have supplied screens.
   (H)   Rodent protection. 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 such other device as will effectively prevent their entrance.
