It is not the intention of this Code to interfere with, evade, or annul any easements, covenants, or other agreements between parties, except that, where this Code imposes a greater restriction upon the use of buildings or land, or upon the height of buildings, or requires larger open spaces or greater lot area per family than are required or imposed by such easements, covenants, or agreements between parties, the provisions of this Code will control. The provisions of this Code will control and supersede the provisions of any ordinances, rules, or regulations previously adopted relating to the use of buildings and premises in all matters which are provided for in this Code, whether specifically or by implication, except for prior ordinances which specify a particular dimension for a front yard or which authorize the location and construction of a public utility installation, which prior ordinances will remain in full force and effect.
