South Carolina Code of Regulations › Chapter 8 - BUILDING CODES COUNCIL › Article 6 - MODULAR BUILDING CONSTRUCTION › Section 8-607 - Approved Inspection Agency Authority

Current through Register Vol. 48, No. 6, June 28, 2024
(1) An approved inspection agency shall
			 conduct inspections at the manufacturing plant to determine compliance with the
			 approved plans, the Act and these regulations. Violations of any of the
			 provisions of these regulations or variations from the approved plans may be
			 cause for revocation of the plan approval and shall be reported to the Council
			 within one (1) day after discovery.
(2) Failure on the part of an approved
			 inspection agency to fulfill its responsibilities or notify the Council of
			 violations of these regulations or variations from the approved plans is cause
			 for revocation of its approval.
(3)
			 An approved inspection agency shall perform final plan review and approval,
			 inspection, and certification of a single family residential modular building.
			 Upon final plan review and approval by an approved inspection agency of a plan
			 as meeting the requirements of the Modular Building Construction Act and the
			 regulations of the council, a copy of the approved plan must be filed with the
			 Department of Labor, Licensing and Regulation. Upon filing of an approved plan
			 with the department by an approved inspection agency, a manufacturer may
			 request from the department certification labels for units manufactured to the
			 approved plan. Each certification label must bear the serial number of the unit
			 for which it is issued and only may be attached upon final inspection by an
			 approved inspection agency.
(4) An
			 approved inspection agency shall perform plan approval, inspection, and
			 certification of commercial or multifamily modular buildings. Upon review by
			 the approved inspection agency, the plans must be submitted to the Department
			 of Labor, Licensing and Regulation for final plan review and approval.
