Ind. Code § 25-28.5-1-33
Nothing in this chapter shall limit the power of political subdivision to regulate the quality and character of work performed by plumbing contractors through the enforcement of building codes and inspections, but no political subdivision shall require any licensee under this chapter to submit to any other form of licensing: Provided, however, That any political subdivision of this state may require any person licensed as a plumbing contractor under the provisions of this chapter to register with some public official of said political subdivision in order that the plumbing inspection officials of such political subdivision may have the records necessary to inspect the work of persons licensed hereunder. Nothing herein contained shall prohibit any political subdivision from charging a reasonable fee for such registration. Failure to register as required by a political subdivision, upon certification of said failure to the commission, at the discretion of the commission may constitute a basis for suspension of any plumbing contractor's license issued under the provisions of this chapter. Repeated and intentional violation of any such registration requirements may at the discretion of the commission constitute a basis for the revocation of a plumbing contractor's license, said proceeding for suspension or revocation to be had under the provisions of section 26 of this chapter.
