S.C. Code Regs. 8-607 - Approved Inspection Agency Authority
(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.
