The Missouri Public Service Commission regulates investor-owned electric, steam, natural gas, water and sewer and telephone companies. Its mission is to ensure Missouri consumers have access to safe, reliable and reasonably priced utility service while allowing those utility companies under our jurisdiction an opportunity to earn a reasonable return on their investment. The PSC also regulates manufacturers and retail dealers who sell new and used manufactured homes and modular units. The commission was established in 1913. The PSC is comprised of five commissioners, who are appointed by the governor.
What is a Manufactured Home and/or Modular Unit?
Manufactured homes and modular units are governed by Chapter
700-010-700.692 of the Revised Statutes of Missouri and Chapter 120-125
of the Code of State Regulations.
Manufactured Home (HUD Home)
Manufactured homes are built to the United States Department of Housing
and Urban Development (HUD) Codes and Safety Standards and apply to
residential units only. HUD homes must have a permanently affixed
metal tag called a HUD label. A HUD label must be affixed to each
transportable section of each manufactured home certifying that the
home was built to HUD construction and safety standards. HUD
homes must remain transportable and the frame must remain intact.
All new HUD homes installed after July 1, 2005 must be installed by a
certified licensed installer of the state of Missouri (see 4 CSR
240-125). In addition, HUD homes must be installed using an
approved tie-down or anchoring system (see 4 CSR 240-124).
Modular Unit
Modular units include residential homes, commercial, industrial and
educational (classroom) units. Modular units are built to
International Residential Codes and International Building Codes.
Each new modular unit sold or placed in the state must contain a
Modular Seal permanently affixed to each modular unit. Seals are
issued by the State of Missouri and certify that the modular unit has
been built to applicable construction and safety standards.
Normally modular units are set-up on a permanent foundation and
anchored to the foundation. Modular units must be installed using
an approved tie-down or anchoring system (see 4 CSR 240-124).
