A. 
No building or structure which does not conform to the requirements of these regulations regarding building height limit and required yards shall be extended or expanded unless such extended or expanded portion conforms to the regulations applying to the district in which it is located.

No building or structure which is on a lot which does not conform to the requirements of these regulations regarding lot area, width of lot, percentage of lot coverage, or parking facilities shall be extended or expanded.
C. 
If any nonconforming building or structure shall be destroyed by any means, repairs or reconstruction may be made and the nonconforming use continued provided there is no expansion of the existing footprint and further provided that such restoration is started within a period of one year from the date of such destruction and is diligently prosecuted.
