Pre-existing legal lots. If any lot, legally platted at the time of its creation, or the aggregate of such contiguous lots or land parcels held in single ownership has an area or dimension less than required for the zoning district in which the property is located, the lot or aggregate holdings may be occupied by any permitted use in the district subject to compliance with all other requirements of the district including the minimum setbacks thereof; provided, however, that the use of a lot in a residential district which has an area deficiency shall be limited to one single-family dwelling. All lots shall have a minimum of 20 feet of access to a public or private street, or access easement. Single ownership of abutting parcels shall not affect the right of the Planning Official to approve development of the single lot that has an area deficiency. (Ord. M-3643, 2004)
