Any lawful use of buildings or land existing at the effective date of this chapter or any relevant amendment hereto may be continued, even though such use does not conform to the provisions hereof. The non-conforming use of a building may be extended throughout those existing parts of the building that were arranged or designed for such use but not into areas of a building designed, constructed and previously used for uses conforming to the regulations of the district in which the structure is located, except with the approval of the Board of Zoning Appeals.
