Denver, Colorado – On January 1, 2025, the International Code Council’s and Modular Building Institute’s (MBI) Standards 1200, 1205 and 1210, as well as Guideline 6: A Guideline on Advanced Panelization became effective in the state of Colorado. Colorado is the second state to adopt ICC/MBI 1210 Standard for Mechanical, Electrical and Plumbing Systems, Energy Efficiency and Water Conservation in Off-site Construction and the first to adopt Guideline 6. The state joins Virginia, Utah, Montana and Rhode Island in adopting ICC/MBI Standards 1200 and 1205 for off-site construction.
In 2024, the Code Council published Guideline 6 which employs lessons learned from international approaches to support efficient delivery of closed panels. Guideline 6provides jurisdictions with guidance on the approval of panelized systems that meet advanced fabrication and monitoring criteria. It helps to efficiently verify compliance with existing criteria including building codes, standards and acceptance criteria.
The Code Council and MBI developed ICC/MBI 1200-2021 Standard for Off-site Construction: Planning, Design, Fabrication and Assembly, ICC/MBI 1205-2021 Standard for Off-site Construction: Inspection and Regulatory Compliance and ICC/MBI 1210-2023 to provide best practices based on existing off-site construction programs and support consistency and efficiency in how off-site construction is approved and inspected. The ICC/MBI standards for off-site construction aid communities in advancing off-site construction while adhering to local building codes.
“This adoption underscores Colorado’s ongoing leadership in advancing housing affordability through off-site construction,” said Code Council Vice President of Innovation Ryan Colker. “With Colorado joining Utah and Montana in adopting the standards, manufacturers in the Mountain West should see the benefits of consistent approvals for off-site construction projects.”
Off-site construction is a rapidly growing, innovative construction method that creates affordable housing with greater speed to market than traditional construction and can support communities in achieving their goals for sustainability, workforce development and jobsite safety. Off-site construction can yield 50% faster construction timelines with higher quality control than traditional construction methods.
