Section 145.64. Modification of industrialized housing or housing components after certification

(a) Certified industrialized housing and certified housing components bearing the insignia of certification may not be modified after the insignia of certification has been attached, unless the modification is approved in advance by the evaluation agency on the basis that the industrialized housing or housing component, as so modified, will still conform to the approved building system documentation. Approvals of modifications which are consistent with the approved building system documentation may be by oral authorization by an officer or employe of the evaluation agency, but in such event each approval shall be subsequently evidenced by a letter from the evaluation agency to the manufacturer within 10 days after the oral authorization. Proposed modifications which are inconsistent with the approved building system documentation shall be treated as proposed amend-ments to the building system documentation subject to the approval of the evaluation agency under § 145.55 (relating to general requirements for approval of amendments to building system documentation).

(b) Modifications of certified industrialized housing or certified housing components are not prohibited under the act or the provisions of this chapter if the modifications are made after the issuance of a certificate of occupancy, or other similar permit, by the local enforcement agency or, if the industrialized housing or housing components have been installed for use in a jurisdiction of local government which does not issue certificates of occupancy, or other similar permit, after occupancy of such industrialized housing or housing structure containing the housing components by a person intending to reside therein for a continuous period of 6 months, unless the modifications are made by the manufacturer or other person with an intent to evade the requirements of the act or this chapter. The modifications referred to in this subsection shall be subject to other applicable laws, codes and ordinances of the Commonwealth and of the local government of the jurisdiction in which the industrialized housing or housing structure is located.

(c) Nothing in this section shall prevent a manufacturer, on its own motion or at the order of the inspection agency or of the Department, from repairing damage to or remedying a defect found in an industrialized housing component.

The provisions of this § 145.64 adopted July 12, 1974, effective July 13, 1974, 4 Pa.B. 1403.
