[Amended 3-4-2020]
(1) 
Lots which abut on more than one public street shall provide the required front setbacks along each and every public street on which that lot abuts, except for a lot in existence on August 23, 2005, that meets the following standards:
(a) 
The lot was created in accordance with all applicable zoning requirements in effect at the time of its creation;
(b) 
The lot is abutted on two or more sides by the street; and
(c) 
The lot meets the frontage requirements for its zoning district on at least one side of the lot.
(2) 
A lot that abuts on both a private street and a public street shall provide the required front setback from any public street on which it abuts and shall provide a thirty-foot front setback on any private street on which it abuts. This subsection shall not apply to lots in existence on August 23, 2005, that meet the standards set forth in Subsection A(1) of this section.
B. 
Frontage requirement. A lot with frontage on more than one street only has to meet the applicable lot frontage requirements of the zoning district in which it is located along one frontage of the lot, regardless of whether the frontage is located on a public street or a private street approved by the Town in accordance with the provisions of § 315-61 of this chapter.
No structures, whether attached to the principal structure or not and whether open or enclosed, including porches, carports, balconies, or platforms above normal grade level, shall project beyond the setbacks provided in this chapter.
In any district, notwithstanding limitations imposed by other provisions of this chapter, a single lot of record at the effective date of adoption of this chapter may be built upon subject to the following conditions:
A. 
Such a lot must be in a separate and distinct ownership from adjacent lots on said date. This provision shall apply even though such lots fail to meet the minimum requirements for area or width, or both, that are generally applicable in the district, provided that yard dimensions of the lot shall conform to the requirements for the district in which the lot is located. Variance of setback requirements shall be obtained only through action of the Board of Adjustment and Appeals.
B. 
If two or more lots or combinations of lots and portions of lots with continuous frontage are in single ownership at the time of the passage or amendment of this chapter, and if all or part of the lots do not meet the requirements for lot width and area as established by this chapter, the lands involved shall be considered to be an individual parcel for the purpose of this chapter, and no portion of said parcel shall be used or sold which does not meet lot width and area requirements established by this chapter, nor shall any division of the parcel be made which leaves remaining any lot width or area below the requirements stated in this chapter.
In any district, notwithstanding limitations imposed by other provisions of this chapter, a lot containing at least 20,000 square feet, or 15,000 square feet if connected to the public sewer system, as shown on a plan of a subdivision duly approved and recorded in the Cumberland County Registry of Deeds prior to the date of the adoption of this chapter, and irrespective of whether said lot was in separate and distinct ownership from adjacent lots on said date, may be built upon, subject to the condition that said lot and proposed construction meet the width, frontage and yard requirements contained in the Zoning Ordinance of the Town of Cumberland which was in effect immediately prior to the adoption of this chapter.
No lot shall be reduced in size by conveyance of a portion thereof unless both of the following standards are met:
A. 
The remaining land is in conformance with the minimum lot size provided for the zoning district in which that land is located; and
B. 
The land conveyed is in conformance with said minimum lot size or is conveyed to the owner of the abutting property.
[Added 5-8-2023]
Notwithstanding any provision of this chapter to the contrary, in the event that any dwelling unit in existence on or after July 1, 2023, is torn down and results in an empty lot, the lot shall not qualify for additional dwelling units pursuant to 30-A M.R.S. § 4364-A, as may be amended from time to time.
