Subject to the provisions of this subchapter, a nonconforming use or structure may be continued but may not be extended or altered, unless necessary to comply with a lawful requirement and unless the use or structure is a less intensive use than the permitted uses in the zone (such as a residence in a conforming residential zone which has been rezoned to industrial). Exceptions:

The accumulated expansion by up to ten percent (10%) of a commercial, industrial or public use or structure in any zoning district that was established prior to December 9, 1981, and that has been in use continuously since December 9, 1981, is permitted, provided no additional land area is being acquired for the expansion.
2. The accumulated expansion of such use identified in subsection A1 of this section by more than ten percent (10%), but no more than fifty percent (50%) is conditionally permitted, provided no additional land area is being acquired for the expansion.
