Do you need a license to work as a plumber in Indiana?
Yes. In Indiana, a person may not work as a plumbing contractor or journeyman plumber without first getting a plumbing contractor or journeyman plumber license from the Indiana plumbing commission. Helpers, laborers, registered apprentices and other employees of a plumbing contractor or journeyman plumber who do not hold themselves out to the public as plumbers are not covered. The chapter does not apply to the owner occupant of a dwelling of eight or fewer residential units who is installing, altering or repairing its plumbing system. This is Ind. Code §§ 25-28.5-1-3, 25-28.5-1-11, 25-28.5-1-32.
