Indiana Code Title 25. Professions and Occupations § 25-23.7-5-1

Sec. 1. (a) Except as provided in subsection (b), an individual may not install a manufactured home without first obtaining from the board a license authorizing the individual to install a manufactured home.  A political subdivision may not require a licensee to submit to any other form of licensing except for that required by a political subdivision for onsite electrical, plumbing, or mechanical systems installation.  However, this article does not limit the power of a political subdivision to regulate the quality and character of work performed by a licensee through the enforcement of building codes or conducting inspections.

(b) An individual acting at all times at the direction and under the supervision of a licensed installer need not be licensed in order to install a manufactured home.  A licensee is fully responsible for all installation work performed under the licensee's direction or supervision.

(c) This section does not prohibit:

from providing maintenance to an installation if that maintenance does not otherwise require a license by a political subdivision for onsite electrical, plumbing, or mechanical systems installation.
