Modular Building Codes
The International Code Council maintains a complete list of uniform building codes and modular construction codes used in every US state—commercial, residential, fire, energy, MEP, and more.
State Contacts
MBI maintains an exclusive list of state-level modular program contacts and state program administrators for the benefits of its members. This list is freely accessible to all MBI members. Contact MBI's government affairs director fo details.

ICC/MBI Standards for Off-Site Construction
Published in partnership with the ICC, these off-site standards bring clarity to the off-site and modular construction processes.
ICC/MBI 1200-2021 Standard for Off-site Construction: Planning, Design, Fabrication and Assembly
This first edition standard provides planning and preparation requirements such as: the role of the architect/modular manufacturer/construction manager/general contractor, location of plant vs. construction site, and material procurement and lead times.
ICC/MBI 1200-2021 includes requirements for:
- A controlled manufacturing environment.
- Supply chain integration.
- Structural modular vs. nonstructural modular.
- The fabrication process and on-site assembly.
ICC/MBI 1205-2021 Standard for Off-site Construction: Inspection and Regulatory Compliance
The scope of this first edition standard is to provide minimum requirements to safeguard the public health, safety and general welfare and address societal and industry challenges for the inspection and regulatory compliance of off-site and modular construction. It addresses the inspection, approval and regulatory compliance of off-site residential and commercial construction components as well as their assembly and completion at the final building site.
ICC/MBI 1210-2023 Standard for Mechanical, Electrical, Plumbing Systems, Energy Efficiency and Water Conservation in Off-site Construction
The scope of this standard is to provide minimum requirements to safeguard the public health, safety, general welfare and address societal and industry challenges for the energy efficiency and water conservation of off-site construction projects and the planning, designing, fabricating, transporting, and assembling, of commercial and residential building mechanical, electrical and plumbing (MEP) system elements. This includes the componentization and modularization of elements of MEP systems, the incorporation of MEP systems in componentized, panelized or modularized building elements, and the achievement of energy efficiency and water conservation requirements in off-site construction.
2019 ICC G5 Guideline for the Safe Use of ISO Shipping Containers
More than 30 million International Organization for Standardization (ISO) intermodal shipping containers are in use around the world today. These containers were built to ISO standards and maintained to standards defined by the International Maritime Organization’s (IMO) “Convention for Safe Containers.” New or used, containers are now repurposed at a pace that makes their reuse a multi-billion-dollar global industry. Containers are regularly repurposed and converted into International Residential Code and International Building Code occupancy uses. As a building material, the applications are widely diverse as is the extent to which the container is used as a structural building element.
