No person shall engage in or work at the trade as journeyperson plumber until he or she shall have first procured a department-issued journeyperson plumber's license.

In addition, no department-licensed journeyperson plumber shall contract or carry out a contract for the construction, installation, repairing or altering of any plumbing, or furnish plumbing material therefor, within the corporation limits of the city, or represent or advertise himself, either publicly or privately, as being ready, willing or able to contract to perform such work or furnish such material within the corporation limits of the city.
