721.01 MINIMUM HEATING STANDARDS.

   Every person who contracts or undertakes or is bound to heat, or furnish heat for any building or portion thereof, occupied as a home or place of residence of one or more persons, or as a business establishment where one or more persons are employed, shall heat, or furnish heat for every occupied room in such building, or portion thereof, so that a minimum temperature of 68°F. may be maintained therein at all such times when so occupied. Wherever a building is heated by means of a furnace, boiler or other apparatus under the control of the owner, agent or lessee, in the absence of a written or verbal contract or agreement to the contrary, such owner, agent or lessee shall be deemed to have contracted, undertaken or bound himself or herself to furnish heat in accordance with the provisions of this section.

   The term "at all such times when so occupied" as used in this section, unless otherwise provided by a contract or agreement, includes the time between the hours of 6:00 a. m. and 10:00 p. m. in a building, or portion thereof, occupied as a home or place of residence, and during the usual working hours established and maintained in a building or portion thereof, occupied as a business establishment, of each day whenever the outer or street temperature falls below 50°F.

   Nothing in this section shall apply to buildings or portions thereof, used and occupied by trades, business or occupations where high or low temperatures are essential and unavoidable. (1967 Code §113.12)
