and the location and boundaries of which are shown on the map and notations thereon titled "The Zoning Map of Calumet City," which said map is on file in the office of the building commission of Calumet City, and together with all notations, references, and other information shown thereon, are a part of this ordinance and have the same force and effect as if said map and all the notations, references and other information thereon were all fully set forth and described herein.

Except as hereinafter provided:

(1)

No building shall hereafter be erected or altered, nor shall any building or premises be used for any purpose other than is permitted in the district in which such building or premises is located.

(2)

No building shall be erected or altered to exceed in height the limit herein established for the district in which such building is located.

(3)

No building shall be erected or altered except in conformity with the area regulations of the district in which the building is located.

(4)

The minimum yards and other open space, including lot area required by the ordinance for each and every building existing at the time of passage of this ordinance, or for any building hereafter erected shall not be encroached upon or considered as yard or open space requirements for any other building.

6.2 District boundaries.

When uncertainty exists with respect to the boundaries of the various districts as shown on the zoning map, the following rules shall apply:

District boundary lines are either the center lines of railroads, highways, streets, alleys or easements, or the boundary lines of sections, quartersections, divisions of sections, tracts or lots, or such lines extended otherwise indicated.

In areas not subdivided into lots and blocks, wherever a district is indicated as a strip adjacent to and paralleling a street or highway, the depth of such strips shall be in accordance with the dimensions shown on the map from section, quarter-section, or division lines, or center lines of streets, highways or railroad rights-of-way unless otherwise indicated.

Where a lot held in one (1) ownership and of record on the effective date of the ordinance is divided by a district boundary line, the entire lot shall be construed to be within the less restricted district, provided that this construction shall not apply if it increases the less restricted frontage of the lot by more than twenty-five (25) feet.

6.3 Zoning of streets, alleys, public ways, waterways and railroad right-of-way.

All streets, alleys, public ways, waterways and railroad rights-of-way, not otherwise specifically designated, shall be deemed to be in the same zone as the property immediately abutting on such alleys, streets, public ways and railroad rights-of-way or waterways. Where the center line of a street, alley, public way, waterway or a railroad right-of-way serves as a district boundary, the zoning of such areas, unless otherwise specifically designated, shall be deemed to be the same as that of the abutting property up to such center line.

6.4 Zoning of annexed land.

All property annexed to the City of Calumet City shall be considered automatically zoned as R-1, unless concurrently with the annexation thereof there shall be adopted after statutory hearing, a zoning ordinance zoning the property for such purposes as is prescribed by the amendatory ordinance. Such amendatory ordinance may be adopted as prescribed by statute after annexing as well as concurrently with annexation.
