The district boundary lines are intended generally to follow the center lines of streets, the center lines of railroad rights-of-way, existing lot lines, the center lines of creeks, streams and other waterways and the Village boundary lines. Where a district boundary line does not follow such a line, its position shall be shown on the Zoning Map by a specific dimension expressing its distance in feet from a street line or other boundary line as indicated.

Where district boundaries are so indicated that they approximately follow lot lines, such lot lines shall be construed to be said boundaries.

Where district boundaries are so indicated that they are approximately parallel to the center of right-of-way lines of streets or highways, such district boundaries shall be construed to be parallel thereto and at such distance therefrom as indicated on the Zoning Map.

Where a district boundary line divides a lot in single ownership on the effective date of this chapter or its amendment, the regulations for the more restricted portion of such lot shall extend not more than 50 feet into the less restricted portion, provided that the lot has frontage on a street in the less restricted district.

In case of uncertainty as to the true location of a district boundary line in a particular instance, the Codes Enforcement Officer shall make a determination with respect thereto.

No building shall be erected and no existing building shall be moved, altered, remodeled, added to or enlarged, nor shall any land or building be designed, used or intended to be used, for any purpose or in any manner other than as specified among the uses hereinafter listed as permitted in the district in which such building or land is located.

No building shall be erected, reconstructed or structurally altered to exceed in height the limit hereinafter designated for the district in which such building is located.[1]

No building shall be erected, no existing buildings shall be altered, added to, remodeled or enlarged, nor shall any open space surrounding any building be encroached upon or reduced in any manner, except in conformity to tile yard, lot area and building location regulations hereinafter designated for the district in which such building or open space is located, nor shall any lot be reduced below the district requirements of this chapter.

No yard or other open space provided about any building for the purpose of complying with the provisions of this chapter shall be considered as providing a yard or open space for any other building, and no yard or other open space on one lot shall be considered as providing a yard or open space for a building on any other lot.

No lot in any R-1, R-2 Residential or MS (Main Street) District shall be used for more than one residential structure unless lot area and yard requirements are met for each dwelling, including required street frontages.
