(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.
Any person contracting to do plumbing work must give bond to the state in the amount of at least $25,000 for (1) all plumbing work entered into within the state or (2) all plumbing work and subsurface sewage treatment work entered into within the state. If the bond is for both plumbing work and subsurface sewage treatment work, the bond must comply with the requirements of this section and section 115.56, subdivision 2, paragraph (e). 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 and, if the bond is for both plumbing work and subsurface sewage treatment work, financial loss by reason of failure to comply with the requirements of sections 115.55 and 115.56. 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 restricted 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.
If a master plumber or restricted master plumber who is in compliance with the bond and insurance requirements of subdivision 2, employs a licensed plumber, the employee plumber shall not be required to meet the bond and insurance requirements of subdivision 2. An individual who is an employee working on the maintenance and repair of plumbing equipment, apparatus, or facilities owned or leased by the individual's employer and which is within the limits of property owned or leased, and operated or maintained by the individual's employer, shall not be required to meet the bond and insurance requirements of subdivision 2.
(a) Each person giving bond to the state under subdivision 2 shall pay the department a bond registration fee of $40 for one year or $80 for two years.
(b) The commissioner shall in a manner determined by the commissioner, without the need for any rulemaking under chapter 14, phase in the bond registration from one year to two years so that the expiration of bond registration corresponds with the expiration of the license issued under section 326B.475 or 326B.49, subdivision 1.
