Any use lawfully occupying a building or land at the effective date of this Chapter, November 2, 1970, or of subsequent amendments hereto, that does not conform to the regulations for the district in which it is located shall be deemed to be a legal non-conforming use and may be continued.

Any building lawfully existing or in the process of construction, at the effective date of this Chapter, November 2, 1970, or of subsequent amendment hereto, that is wholly or partially used or designed for use contrary to the regulations for the district in which it is located shall be deemed to be a legal non-conforming building and may be so used or continued in use. Any building under construction as described herein shall be completed within six (6) months in order to qualify as a non-conforming use or shall be made to conform if not completed within such six (6) month period.

No non-conforming use may be enlarged or extended in such a way as to occupy any required open space on any land beyond the boundaries of the lot or parcel of land as it existed at the effective date of this Chapter, November 2, 1970, or to displace any conforming use in the same building or on the same parcel.

In the event that a non-conforming use of any building or premises is discontinued, or its normal operations stopped, for a continuous period of six (6) months, use of such building or premises shall thereafter conform to the use regulations in the district in which the same is located.

Nothing contained herein shall forego the existing powers of the Governing Body of the City in the gradual elimination of non-conforming uses and the buildings; provided, that reasonable periods for amortization or particular uses and buildings shall be required as determined by the Governing Body.
