Join MBI

Joining MBI will give you access to information and resources to help you remain competitive and strong in a volatile business climate. MBI provides tools that you can apply to your operations – strengthening the ties to your customers and the community you serve. 


MBI's members include manufactureres and dealers of code compliant relocatable buildings, as well as permanent modular construction contractors, while our associate members include companies supplying building components, services, and financing. Our membership expanded in 2014 to include owners/developers, architects/engineers, and general contractors interested in modular construction. Individual members are students, professors, and professionals who are not employees of companies engaged in modular construction. It is MBI’s mission to expand the use of offsite construction through innovative construction practices, outreach and education to the construction community and customers, and recognition of high-quality modular designs and facilities.
