In the interpretation and application, the provisions of the Zoning Ordinance shall be held to be minimum requirements adopted for the promotion of the public health, morals, safety, comfort, convenience or general welfare. It is not intended by the Zoning Ordinance to repeal, abbrogate, annul or in any way to impair or interfere with any existing provision of law or ordinance other than the above described Zoning Ordinance, or with any rules, regulations or permits previously adopted or issued or which shall be adopted or issued pursuant to the law relating to the use of buildings or premises; provided, however, that where the Zoning Ordinance imposes a greater restriction than is required by existing ordinance or by rules, regulations or permits, the provisions of the Zoning Ordinance shall control.
