(1) At the time of application for licensure as a master plumber or at the time of renewal of the master's license, the applicant or licensee shall designate on the application if he intends to engage in the business of a master plumber as master plumber of record under his own name, or under an assumed name doing business as a sole proprietor.

(2) If such master intends to affiliate with a partner, firm or corporation as master plumber of record, he shall so designate the name of the firm, partnership or corporation.

(3) If at any subsequent time he should change his status as designated above, he shall immediately notify the board in writing by certified mail to that effect at least ten days prior to the change. Until receiving such notice, the board will consider him to be engaged in business in his prior designated status.

(4) A master license shall be affiliated with only one plumbing business as master plumber of record, to be listed on the annual renewal form, and may not affiliate with a second plumbing business as master plumber of record, without terminating the first through written notice to the board office.

(5) A master plumber shall be responsible for supervising all plumbing work performed by the business with which the master is affiliated and for ensuring all plumbing work is performed by licensed plumber employees where a license is required.
