Building code dispute? Request an interpretation.

Indiana Code 22-13-5 grants the state building commissioner in the Indiana Department of Homeland Security the authority to interpret a building law or a fire safety law. Upon the written request of an interested person, the state building commissioner shall issue a written interpretation of a building law or a fire safety law not later than ten (10) business days after the date of receiving a request. Further, the state building commissioner may issue a written interpretation of a building law or fire safety law whether or not the county or municipality has taken any action to enforce the building law or fire safety law. This means a home builder does not have to wait to be red-tagged before requesting a written interpretation. Finally, a written interpretation binds the interested person and the county or municipality with whom the interested person has the dispute until the written interpretation is overruled by the Indiana Fire Prevention and Building Safety Commission. A written interpretation of a building law or fire safety law binds all counties and municipalities if the state building commissioner publishes the written interpretation of the building law or fire safety law in the Indiana Register.
