It is the purpose of this subchapter to provide for the regulation of nonconforming uses, buildings and structures and to specify those circumstances and conditions under which nonconforming uses, buildings and structures may be continued. It is, however, the purpose and intent of this subchapter that all nonconforming uses shall be eventually eliminated. This subchapter shall be liberally construed to this end.
