State Statutes and Plumbing Codes in Indiana

Plumbing regulations in Indiana are established through a combination of state statutes and administrative rules. The primary regulatory framework for plumbing installations is found in the Indiana Administrative Code (IAC), specifically under Title 675, which is managed by the Fire Prevention and Building Safety Commission. These rules adopt national model codes as a base, which are then modified by Indiana-specific amendments to address local requirements and standards.

Furthermore, the licensing of plumbing professionals—including contractors and journeymen—is governed by Indiana Code (IC) Title 25, Article 28.5, and is administered by the Indiana Plumbing Commission.
