The city community development director or city building official may permit any licensed plumber to have a service key, which he or she shall keep in his or her possession, and with which he or she may shut off the curbcock for the purpose of making repairs on the premises. No person other than a licensed plumber shall use this key, and plumbers shall leave a curbcock in the condition in which it was found. (2002 Code § 13.04.150; amd. 2013 Code)
