Industrialized Building Systems (Modular)/Mobile Structures
The Code Enforcement division is responsible for the administration and enforcement of the Industrialized Building Systems (Modular)/Mobile Structures certification program. For the rules that govern the administration and enforcement of the Industrialized Building System (Modular)/Mobile Structures program, can be found in The Special Administrative Rules for Industrialized Building System and Mobile Structures (675 IAC 15-1) which are adopted by the Fire Prevention and Building Safety Commission.
The certification program includes the review and release of plans for each system under which an Industrialized Building System (Modular) and Mobile Structures are to be built, as well as in-plant inspection being performed. A system is based upon the units completed width and number of stories. A certification label is required for each unit comprising a completed structure.
The in-plant inspections are conducted by either personnel from the Code Enforcement Division or by an authorized third party inspection company. Each unit must be inspected at one point during construction to be eligible to receive a certification label. Each certification label has a unique serial number and is placed upon the electric service panel to identify the unit as certified for use in Indiana. The Indiana certification label is a die cut sticker in the shape of the state in blue for mobile structures and gold for industrialized building systems (modular).
Industrialized Building System (Modular)/Mobile Structures FAQ
Q: What is an Industrialized Building System?
A: IC 22-12-1-14: "Industrialized building system" means any part of a building or other structure that is in whole or in substantial part fabricated in an off-site manufacturing facility for installation or assembly at the building site as part of a Class 1 structure, a Class 2 structure, or another building or structures. However, the term does not include a mobile structure or a system that is capable of inspection at the building site.
Q: What is a Mobile Structure?
