This regulation shall be known and may be cited as the "Boston Zoning Code."

The purposes of this code are hereby declared to be: to promote the health, safety, convenience, morals and welfare of the inhabitants of the City; to encourage the most appropriate use of land throughout the City; to prevent overcrowding of land; to conserve the value of land and buildings; to lessen congestion in the streets; to avoid undue concentration of population; to provide adequate light and air; to secure safety from fire, panic and other dangers; to facilitate adequate provision for transportation, water, sewerage, schools, parks and other public requirements; and to preserve and increase the amenities of the City.

In their interpretation and application, the provisions of this code shall not be construed to repeal, abrogate, annul or in any way impair or interfere with the provisions of other regulations, laws or ordinances except Chapter 488 of the Acts of 1924, as amended, which is repealed on the effective date of this code, or with provisions of private restrictions placed upon property by covenant, deed or other private agreement, or with provisions of restrictive covenants running with the land to which the City is a party. Where this code imposes a greater restriction than is imposed or required by any of the aforesaid provisions, the provisions of this code shall prevail.
