A nonconforming building, structure or improvement is one which lawfully existed on any lot or premises at the time the first zoning or districting regulation became effective with which such building, structure or improvement, or portion thereof, did not conform in every respect.
Any such nonconforming building, structure or improvement may be continued and maintained, except as otherwise provided in this chapter, but may not be moved in whole or in part unless and except every portion thereof is made to conform to the provisions of this title.
