In interpreting and applying the provisions of this title, these provisions shall be held to be the minimum requirements for the promotion of the public peace, health, safety, convenience, comfort, prosperity or general welfare.

It is not intended by this title to abrogate, annul, impair or interfere with any existing or future provision of law or ordinance or with any easements, covenants or other agreements between parties; provided, however, that where this title imposes a greater restriction upon the use or occupancy of buildings or premises or upon the height or location of buildings or structures or upon the lot area per family, size of yards and open spaces, number of garages or other requirements whatsoever, than is imposed or required by such existing laws, ordinances, easements, covenants or agreements, the provisions of this title shall govern.

In any case where there is difficulty in interpreting and applying the provisions of this title to any specific case or situation, the planning commission may, upon its own motion, interpret the intent of this title by resolution, and the interpretation shall be followed in applying the provisions. Any person may request such an interpretation by filing an application with the planning commission together with a filing fee as established by the city council. Any person aggrieved by any such interpretation by the planning commission may appeal the same to the city council by filing written notice thereof with the city clerk together with a filing fee as established by the city council. The city council may, on appeal or on its own motion, review, modify, reverse or affirm any decision of the planning commission made hereunder.
