A. 
A nonconforming lot, structure or use may continue, be bought or sold, altered, restored or extended subject to the provisions of this article even though such lot, structure or use does not conform to the regulations established for the zoning district in which it is located.
B. 
Nothing herein contained shall require any change in plans, construction or designated use of a building or structure for which a permit has been issued and the construction of which shall have diligently pursued within two months of the date of such permit and the ground story framework of which shall have been completed within four months of the date of the permit and which entire building shall be completed according to such plans as filed within one year from the date of the permit.

In any zoning district in which single-family detached dwellings are permitted, a single-family detached dwelling and customary accessory structures may be erected on any single nonconforming lot if the lot is in separate ownership and not of continuous frontage with other lots in the same ownership (provided that other requirements not involving lot area or lot width shall conform to the regulations for the zoning district in which such lot is located). This provision shall apply even though such lot fails to meet the requirements for lot area or lot width that are generally applicable in the zoning district. Variation of yard requirements shall be obtained only through action of the Zoning Hearing Board as provided for by § 195-157, Variance.

Where two or more such nonconforming lots of record abut each other and are in single ownership, they shall be combined prior to development to effect a more conforming situation.

A. 
No nonconforming use of a lot shall be moved in whole or in part to any other portion of the lot occupied by such use at the effective date of adoption or amendment of this chapter.

(1) 
The extension does not encroach upon the lot area requirements, minimum setbacks, zoning or land development requirements of the district in which the nonconforming use is presently located.
(2)

(5) 
Adequate parking can be provided in conformance with this chapter to serve both the original and expanded use.
(6) 
Such expansion does not present a threat to the health or safety of the community or its residents.

(1) 
The extension does not encroach upon the lot area requirements, minimum setbacks, the maximum building height requirements or other zoning and land development requirements of the district in which the nonconforming use is presently located.
(2) 
The extension is for the purpose of expanding the nonconforming use which was in existence at the time of the adoption of this chapter.
