Except as hereinafter specified, no land, building, structure or premises shall hereafter be used, and no building or part thereof, or other structure shall be located, erected, moved, reconstructed, extended, enlarged or altered except in conformity with the regulations herein specified for the district in which it is located. Such regulations include, but are not limited to the following: the use of buildings, structures or land, including performance standards for the control of any "dangerous and objectionable elements", as defined herein, in connection with such use; the height, size, dimensions of building or structures; the size or dimensions of lots, yards and other open spaces surrounding buildings; and the provision, location, size, improvement and operation of off-street parking, loading and unloading spaces.
(Ord. 196. Passed 11-21-63.)

Uses other than those specifically mentioned in this Zoning Code as permitted uses, in each of the districts may be allowed provided that in the judgment of the Board of Zoning Appeals, as evidenced by resolution of record, such other uses are of similar character to those mentioned and will have no adverse influence or no more adverse influence on adjacent properties or the neighborhood or the community than the permitted uses specifically mentioned for the district.
(Ord. 196. Passed 11-21-63.)

Uses other than those specifically prohibited in this Zoning Code in any district shall also be prohibited therefrom, provided that in the judgment of the Board of Zoning Appeals, as evidenced by resolution of record, such other uses are similar in character to those specifically prohibited in that they would have similar or more serious adverse influence on adjacent properties or the neighborhood or the community than the uses specifically mentioned as prohibited in the district.
(Ord. 196. Passed 11-21-63.)

The conversion of any building into a dwelling or the conversion of any dwelling so as to accommodate an increased number of dwelling units or families, shall be permitted only within a district in which a new building for similar occupancy would be permitted under this Zoning Code and only when the resulting occupancy will comply with the requirements governing new construction in such district, with respect to minimum lot size, lot area per dwelling unit, percentage of lot coverage, dimension of yards and other open spaces and off-street parking. Each conversion shall also be subject to such further requirements as may be specified hereinafter within the chapter applying to such district. The aforesaid requirements with respect to lot coverage, yards and other open spaces shall not apply in case the conversion will not involve major exterior structural changes and:

(a) There is either a shortage of not more than ten percent in the required dimensions or area of each of not more than two such requirements as to coverage, yards and other open spaces; or

(b) In case the conversion will result in lot area per dwelling unit or family, at least twenty percent greater than required for new buildings in the district.
(Ord. 196. Passed 11-21-63.)

No building in the rear of a principal building on the same lot shall be used for residential purposes unless it conforms to all the yard and other open space and off-street parking requirements of this chapter, and for the purpose of determining the front yard in such cases, the rear line of the required yard for the principal building front shall be considered the front line for the building in the rear. In addition, there must be provided for any such rear dwelling, an unoccupied and unobstructed accessway not less than ten feet wide to a public street for each dwelling unit in such dwelling, or one not less than thirty feet wide for three or more dwelling units.
(Ord. 196. Passed 11-21-63.)

In any R-1 or R-2 District, a transitional use shall be permitted on a lot, the side lot line of which adjoins either directly or across an alley of any "B" or "M" District. The permitted transitional uses for any lot in an R-1 District shall be any use permitted in the R-2 District, and for any lot in an R-2 District, any use permitted in the R-3 District. In the case of any such lot in an R-1 or R-2 District, the requirements governing lot area per dwelling unit, off-street parking, yards and other open spaces, shall be the same as for the next following less restricted district listed in Chapters 1117, 1121 and 1125. Any transitional use authorized under this section shall not extend more than 100 feet from the side lot line of the lot abutting on the zoning district boundary line.
(Ord. 196. Passed 11-21-63.)

Along any zoning boundary line, on a lot adjoining such boundary line in the less restricted district, any abutting side yard, rear yard or court, unless subject to greater restrictions or requirements stipulated by other provisions of this Zoning Code, shall have a minimum width and depth equal to the average of the required minimum width or depth for such side yards, rear yards or courts in the two districts on either side of such zoning boundary line. In cases where the height of a proposed structure on such lot in the less restricted district is greater than the maximum height permitted in the adjoining more restricted district, the minimum depth or width of the side yard, rear yard or court for such structure shall be determined by increasing the minimum width or depth for the highest structure permitted in such more restricted district by one foot for each two feet by which the proposed structure exceeds the maximum height permitted in the more restricted district.
(Ord. 196. Passed 11-21-63.)


(a) General. An accessory building may be erected detached from the principal building or may be erected as an integral part of the principal building, or it may be connected therewith by a breezeway or similar structure. Except as provided in Chapter 1181, no accessory building shall be erected in any required yard or court, except a rear yard, and shall not occupy more than thirty-five percent of a required rear yard. Accessory buildings shall be a distance of at least six feet from any dwelling situated on the same lot, unless an integral part thereof; at least six feet from any other accessory building; and at least three feet from all lot lines of adjoining lots which are within any R-District.

(b) Corner Lots. In any R-District, where a corner lot adjoins in the rear a lot fronting on the side street and located in an R-District, no part of an accessory building on such corner lot within twenty-five feet of the common lot line shall be nearer to a side street lot line than the least depth of the front yard required along such side street for a dwelling on such adjoining lot, and in no case shall any part of such accessory building be nearer to the side street lot line than the least width of the side yard required for the principal building to which it is accessory.

(c) Front Setback. No accessory use or structure in any R-District, except an off-street parking area subject to the provisions of Chapter 1145, shall be permitted nearer to any front lot line than sixty feet, unless such use or structure is contained within or connected thereto. In case of a corner lot, where choice by the owner of the longer street lot line has been approved as the front lot line, this requirement shall apply only to the distance of an accessory building from the shorter street lot line.

(d) Yard Requirements. Except as provided in Chapter 1177, an accessory building, if not located in the rear yard, shall be an integral part of, or connected with, the principal building to which it is accessory and shall be so placed as to meet all yard and court requirements for a principal building of the same height and other dimensions as the accessory building.

(e) Without Main Building. In any R-District no accessory building or structure shall be erected or constructed prior to the erection or construction of the principal or main building.
(Ord. 196. Passed 11-21-63.)

Except as permitted by other provisions of this Zoning Code, no lot shall contain any building used in whole or part for residential purposes unless such lot abuts for at least twenty feet on a street and there shall be not more than one single-family dwelling for such frontage.
(Ord. 196. Passed 11-21-63.)

In any R-District on any corner lot, no fence, structure or planting shall be erected or maintained within twenty feet of the corner (the point of intersection of the right-of-way line), which interferes with traffic visibility across the corner.
(Ord. 196. Passed 11-21-63.)

No lot, yard, court, parking area or other space shall be reduced in area or dimension so as to make such area or dimension less than the minimum required by this Zoning Code.
