(a)

(1) An industrialized building manufactured after the effective date of the rules adopted pursuant to Code Section 8-2-113 which is sold, offered for sale, or installed within this state must bear the insignia of approval issued by the commissioner.

(2) This Code section shall not apply to industrialized buildings which are inspected and approved by a local government which has jurisdiction at the site of installation and which are inspected at the place of and during the time of manufacture in accordance with standards established by the commissioner. The cost of the inspection shall be borne by the manufacturer. The commissioner shall be notified of the installation of all such buildings in a manner as the commissioner shall prescribe by rule.

No ordinance or regulation enacted by a county or municipality shall exclude residential industrialized buildings from being sited in such county or municipality in a residential district solely because the building is a residential industrialized building.

(4) Industrialized buildings which have been inspected and approved by a local government agency shall not be modified prior to or during installation unless approval for the modification is first obtained from the local government agency.

(c) The commissioner by rule shall establish a schedule of fees to pay the costs incurred for the work related to administration and enforcement of this Code section.
