(a) Required. Every contractor licensee shall be required to have in his or her employ a supervisor who holds a supervisor certificate of qualification for that particular license. A plumbing contractor registrant shall be required to have in his or her employ a supervisor who holds a valid master plumber's license issued by the State of Colorado. An electrical contractor registrant shall be required to have in his or her employ a supervisor who holds a valid master's electrician license issued by the State of Colorado. Plumbing and electrical supervisors shall not be required to hold a supervisor's certificate of qualification.

(b) Validity. The license shall be valid only as long as the named supervisor shall remain in the employ of the licensee in an active, full-time capacity and shall provide personal supervision at the work, job or project site in the city adhering to reasonable standards of personal attendance as determined by the building division.

(c) Effect of supervisor termination or change in status. If the supervisor should leave the employ of the licensee or should be placed on inactive or part-time status, the licensee shall notify the building division in person or by mail within five business days after the supervisor's termination or change of status. For notification by mail, notification shall be effective upon receipt by the building division. Failure of the licensee to so notify the building division shall be cause for suspension or revocation of the license or registration certificate. The licensee shall be required to obtain a certified supervisor within 15 days after the date the supervisor leaves the employ of the licensee or his or her status changes. If a replacement is not employed in an active full-time capacity within the 15-day period, the license shall be deemed suspended until such supervisor is obtained and the building division is notified accordingly.

(d) Effect of lack of personal supervision. Failure of the supervisor to provide personal supervision at the work, job or project site in the city adhering to reasonable standards of personal attendance as determined by the building division shall be cause for suspension or revocation of the license. Violation of this duty shall be cause for suspension or revocation of the license, regardless of whether such supervisor or replacement supervisor complies subsequent to the notification of the suspension or revocation by building division.
