Manufactured Housing Overview

The Public Service Commission began regulation of Manufactured Housing on January 1, 1974. The Manufactured Housing Department became a State Administrative Agency (SAA) for the Housing and Urban Development (HUD) Manufactured Housing Program on June 15, 1976.

The Manufactured Housing and Modular Unit Program is governed by Chapter 700.010-700.692 of the Revised Statutes of Missouri and Chapter 120-125 of the Code of State Regulations.

The Manufactured Housing and Modular Unit Program is staffed by the Program Manager, an Inspection Supervisor, four Manufactured Housing Inspectors, and two Clerical Support Personnel.

The Manufactured Housing and Modular Unit Program is responsible for overseeing the annual registration of dealers and manufacturers of manufactured homes and modular units as well as the installers of new manufactured homes.  The Program also is responsible for prescribing and enforcing uniform construction, safety and installation standards by conducting code and installation inspections, which includes enforcing tie down and anchoring requirements.   

Consumers who have questions and/or complaints regarding manufactured home or modular units may contact the Manufactured Housing and Modular Unit Program.  The Commission staff conducts free home inspections for consumers who file inspection requests/complaints with the Commission.  The Staff successfully resolves complaints through its formal process of working with manufacturers, dealers, installers and homeowners.
