1. Zoning Lot. In this chapter the term “lot” refers to a “zoning lot” unless the context clearly indicates that it refers instead to a “lot of record.” A zoning lot is a single tract of contiguous land which, at the time of filing for a building permit or a certificate of occupancy or district boundary change, is designated by the owner or developer as a tract to be used, developed, or built upon as a unit under single or unified ownership or control and assigned to the particular use, building, or structure for which the building permit or certificate of occupancy is issued. A lot includes such area of land as may be required by the provisions of this chapter for such use, building, or structure.
2. Lot Street Frontage and Access Required. No lot shall be created or any principal building constructed or placed on any lot or tract of land unless such lot or tract has frontage on either a public street or on a private street which has been specifically approved by the Council for that purpose. In order to be approved, such street shall provide permanent and unobstructed vehicular access, have a roadway of adequate width and surface, and meet all other applicable standards and requirements, established by the City. No lot shall be used for residential purposes unless such lot has at least a 35-foot frontage on such street.
3. Division of Lot. No improved lot shall hereafter be divided into two or more lots and no portion of any improved lot shall be sold unless all lots resulting from each division or sale shall conform to all the applicable bulk regulations of the district in which the property is located.
4. Number of Principal Buildings Permitted on a Lot. In all RM, C, and I districts, more than one principal institutional public or semi-public, multi-family, commercial, or industrial building may be located on a lot provided that no such building or portion thereof is located outside the buildable area of the lot. However, in all RS and RD districts, except in the case of Planned Area Developments, not more than one detached one- or two-family residential building shall be located on the same lot with any other principal building.
5. Lot of Record. In any residence district on a lot of record, on the effective date of the Zoning Ordinance, a single-family dwelling may be established even though the lot area and width do not meet the minimum district requirements, provided all other requirements of this code are met. However, where two or more contiguous substandard recorded lots are in common ownership and are of such size that together they constitute at least one conforming “zoning lot,” such lots or portions thereof shall be so joined and re-platted for the purpose of forming an effective and conforming zoning lot or lots.
