Legislative coalitions have been created for the advancement of the interior design profession. IIDA Indiana Chapter supports the efforts of the Interior Design Coalition of Indiana, a separate organization. The IIDC represents one unified voice for interior design professionals and allied design professionals who practice interior design in the state of Indiana and show minimum competency based upon national interior design standards.
On July 1, 2009 a Title Act was effective in the form of the Indiana Interior Design Registry. The Indiana General Assembly passed HEA 1573 allowing Interior Designers the right to register with the State of Indiana through the Indiana Professional Licensing Agency (IPLA).
