[Amended 6-28-2011 by L.L. No. 5-2011]
The Village of Bronxville is hereby divided into the following districts:
One-Family Residence AAA District
One-Family Residence AA District
One-Family Residence A District
Two-Story Multiple Residence B District
Three-Story Multiple Residence C District
Six-Story Multiple Residence D District
Central Business A District
Service Business B District
Controlled Development CD District
Central Business A Transition District
The boundaries of the districts are hereby established as shown on the "1995 Zoning Map of the Village of Bronxville," which is found at the end of this chapter and which, with all explanatory matter thereon, is hereby adopted and made a part of this chapter. Said map, indicating the latest amendments, shall be kept up to date in the office of the Superintendent of Buildings and the office of the Village Clerk for the use and benefit of the public.
In determining the boundaries of districts shown on the map, the following rules shall apply:
A. 
Unless otherwise shown, the district boundaries shall be construed to coincide with the center lines of streets, alleys and main track or tracks of railroads.
B. 
Where such boundaries are indicated as approximately following the property lines of parks or other publicly owned lands, such lines shall be construed to be such boundaries.
C. 
In all cases where a district boundary divides a lot in one ownership and more than 50% of the area of such lot lies in the less restricted district, the regulation prescribed by this chapter for the less restricted district shall apply to the portion of the more restricted portion of said lot which lies within 30 feet of such district boundary. For purposes of this section, the more restricted district shall be deemed that district which is subject to regulations which prohibit the particular use intended to be made of said lot or which regulations require higher standards with respect to setbacks, coverage, yards, screening, landscaping and similar requirements.
D. 
In all cases where a district boundary line is located not farther than 15 feet away from a lot line of record, such boundary line shall be construed to coincide with such lot line.
E. 
In all other cases where dimensions are not shown on the map, the location of boundaries shown on the map shall be determined by the use of the scale appearing thereon.
F. 
Where a question arises as to the exact boundary of a zoning district, the Zoning Board of Appeals of the Village may by resolution determine the location of the boundary, giving due consideration, among other factors, to the indicated location of the boundary on the Zoning Map, the scale appearing thereon and the expressed intent and purpose of this chapter.
Following the effective date of the Village of Bronxville Zoning Ordinance of 1958 or any applicable amendments thereto:
A. 
No building shall be erected, moved, altered, rebuilt or enlarged, nor shall any land or building be used, designed or arranged to be used for any purpose or in any manner except in conformity with all regulations, requirements and/or restrictions specified in this chapter for the district in which such building or land is located.
B. 
No yard or open space required in connection with any building or use shall be considered as providing a required open space for any other building on the same or any other lot.
C. 
No lot shall be formed from part of a lot already occupied by a building unless such building, all yards and open spaces connected therewith and the remaining lot comply with all requirements prescribed by this chapter for the district in which said lot is located. No permit shall be issued for the erection of a building on any new lot thus created unless such building and lot comply with all the provisions of this chapter.
D. 
The minimum lot dimension or lot area regulations or both, shall not apply to any lot with an area, width and/or depth of less than prescribed herein, provided that:
(1) 
Such lot was under different ownership from that of any adjoining land on the effective date of the Village of Bronxville Zoning Ordinance of 1958 or any amendments thereto;
(2) 
If the proposed improvement of the lot would not have been unlawful immediately prior to the effective date of the Village of Bronxville Zoning Ordinance of 1958 or any amendments thereto; and
(3) 
Such lot shall be subject to all other applicable regulations prescribed by this chapter.
E. 
Nothing contained in this chapter shall require a change in the plans, construction or designated use of a building complying with existing law, a permit for which shall have been duly issued and the construction of which shall have been started before the effective date of the Village of Bronxville Zoning Ordinance of 1958, or any amendments thereto, and the ground story framework of which, including the second tier of beams, shall have been completed within six months of the date of the permit and which entire building shall have been completed in accordance with such plans as have been filed within one year from the effective date of the Village of Bronxville Zoning Ordinance of 1958, or any amendments thereto.
