Industrialized/Modular Buildings and Mobile Homes Program:

• GENERAL (January 7, 2010)
  • The industrialized (modular) building industry has expanded the role it plays in fulfilling the nation's housing and commercial building needs. In addition, industrialized (modular) buildings are frequently being used for schools, offices, convenience stores, hospitals, motels and other commercial buildings.
    
    The State of Maryland has adopted a statewide regulatory program for industrialized (modular) construction, whereby the Maryland Department of Housing and Community Development, Codes Administration, adopts and enforces construction standards for industrialized (modular) buildings. In the State of Maryland, local jurisdictions are pre-empted from adopting construction Standards for industrialized (modular) construction.
    
    Following is a list of applicable Standards which constitute the State Model Performance Code (Ref: COMAR 05.02.01) for Industrialized (modular) building construction:
    
    Applicable Standards - The State Model Performance Code (Ref: COMAR 05.02.01)
    
    
    • (Effective January 1, 2010)
    • International Building Code (IBC) 2009 w/modifications (Ref: COMAR 05.02.07)
    • International Plumbing Code (IPC) 2009 w/a modification (Ref: COMAR 05.02.02)
    • International Mechanical Code (IMC) 2009
    • National Electrical Code (NEC) 2008
    • International Energy Conservation Code (IECC) 2009
    • International Residential Code (IRC) 2009 w/modifications (Ref: COMAR 05.02.07)
    • Maryland Accessibility Code (Ref: COMAR 05.02.02)
    • NFPA 101 Life Safety Code 2009 with modifications (Ref. COMAR 29.06.01.07)
    
    While local jurisdictions are excluded from enforcing the construction standards for industrialized (modular) buildings and manufactured homes, local officials continue to play an important role in the regulation of these units by inspecting their installation and all on-site work. The installation of these units is a critical step in the overall process of building and delivering safe buildings. The on-site work requires careful oversight since it is frequently performed by crews not affiliated with the manufacturer and involves:
    
    
    • Construction of safe foundations and anchorage system
    • Proper assembly of building components
    • Proper connection of all electrical, plumbing and mechanical systems
    • Performance of all site preparation work
    
    Local fire control measures, land use and development, including zoning and site preparation, remain under the regulatory authority of local jurisdictions.
