(1) The department shall adopt by rule a temporary worker building code in conformance with the temporary worker housing standards developed under the Washington industrial safety and health act, chapter 49.17 RCW, and the following guidelines:

     (a) The temporary worker building code shall provide construction standards for shelter and associated facilities that are safe, secure, and capable of withstanding the stresses and loads associated with their designated use, and to which they are likely to be subjected by the elements;

     (b) The temporary worker building code shall permit and facilitate designs and formats that allow for maximum affordability, consistent with the provision of decent, safe, and sanitary housing;

     (c) In developing the temporary worker building code the department of health shall consider:

     (i) The need for dormitory type housing for groups of unrelated individuals; and

     (ii) The need for housing to accommodate families;

     (d) The temporary worker building code shall incorporate the opportunity for the use of construction alternatives and the use of new technologies that meet the performance standards required by law;

     (e) The temporary worker building code shall include standards for heating and insulation appropriate to the type of structure and length and season of occupancy;

     (f) The temporary worker building code shall include standards for temporary worker housing that are to be used only during periods when no auxiliary heat is required; and

     (g) The temporary worker building code shall provide that persons operating temporary worker housing consisting of four or fewer dwelling units or combinations of dwelling units, dormitories, or spaces that house nine or fewer occupants may elect to comply with the provisions of the temporary worker building code, and that unless the election is made, such housing is subject to the codes adopted under RCW 19.27.031.
