This Code is not intended to revoke or repeal any easement, covenant, or other agreements between private parties. However, where the regulations of this Code are more restrictive or impose higher standards or requirements than such easement, covenant, or other agreements between private parties, then the requirements of this Code shall govern in accordance with applicable Arizona law. Nothing in this Code shall modify or repeal any private covenant or deed restriction, but such covenant or restriction shall not excuse any failure to comply with this Code. In no case shall the City be obligated to enforce the provisions of any easements, covenants, or agreements between private parties, unless the City is a party to such agreements and only if the City decides, in its discretion, to pursue enforcement action.
