    Subdivision 1. License required. (a) No person shall engage in or work at the business of
a master plumber, restricted master plumber, journeyman plumber, and restricted journeyman
plumber unless licensed to do so by the state commissioner. A license is not required for
individuals performing building sewer or water service installation who have completed pipe
laying training as prescribed by the commissioner of labor and industry. A master plumber may
also work as a journeyman plumber, a restricted journeyman plumber, and a restricted master
plumber. A journeyman plumber may also work as a restricted journeyman plumber. Anyone not
so licensed may do plumbing work which complies with the provisions of the minimum standards
prescribed by the Plumbing Board on premises or that part of premises owned and actually
occupied by the worker as a residence, unless otherwise forbidden to do so by a local ordinance.
    (b) No person shall engage in the business of planning, superintending, or installing
plumbing or shall install plumbing in connection with the dealing in and selling of plumbing
material and supplies unless at all times a licensed master plumber, or in cities and towns with
a population of fewer than 5,000 according to the federal census, a restricted master plumber,
who shall be responsible for proper installation, is in charge of the plumbing work of the person,
firm, or corporation.
    Subd. 2. Bond; insurance. Any person contracting to do plumbing work must give bond to
the state in the amount of $25,000 for all work entered into within the state. The bond shall be for
the benefit of persons injured or suffering financial loss by reason of failure to comply with the
requirements of the State Plumbing Code. The bond shall be filed with the commissioner and
shall be written by a corporate surety licensed to do business in the state.
    In addition, each applicant for a master plumber license or renewal thereof, shall provide
evidence of public liability insurance, including products liability insurance with limits of at least
$50,000 per person and $100,000 per occurrence and property damage insurance with limits of at
least $10,000. The insurance shall be written by an insurer licensed to do business in the state
of Minnesota and each licensed master plumber shall maintain on file with the commissioner a
certificate evidencing the insurance providing that the insurance shall not be canceled without
the insurer first giving 15 days written notice to the commissioner. The term of the insurance
shall be concurrent with the term of the license.
    Subd. 3. Bond and insurance exemption. If a master plumber who is in compliance with the
bond and insurance requirements of subdivision 2 employs another master plumber, the employee
