The lawful use of a building existing at the adoption of this Chapter may be continued even though such does not conform with the provisions hereof.

Whenever the use of a building becomes nonconforming through a change in the zoning ordinance or district boundaries, such use may be continued as long as it remains used in that manner.

If no structural alterations are made, a nonconforming use of a building may be changed to another nonconforming use of the same or more restricted classifications. Whenever a nonconforming use of a building has been changed to a more restricted use or to conforming use, such shall not thereafter be changed to a less restricted use.

When a nonconforming building or use, is damaged either partially or wholly by fire, act of God, or the public enemy, it may be restored.

No such nonconforming use shall be enlarged or increased nor extended to occupy a greater area of land than was occupied at the effective date of adoption or amendment of this Chapter.

In the event that a nonconforming use of any building or premises is discontinued, or its normal operation stopped, for a period of six (6) months, the new use must be a permitted use listed in this Chapter for the zoning classification in that area the buildings are in.

A nonconforming use occupying only a portion of a building may be extended throughout the building.

On any building or structure devoted in whole or in part to any nonconforming use, work may be done in any period of twelve (12) consecutive months on ordinary repairs, or on repair or replacement of non-bearing walls, fixtures, wiring or plumbing, to an extent not exceeding thirty-three percent (33%) of the building as it existed at the time of passage or amendment of this Chapter.

Any manufactured home that does not comply with the HUD Manufactured Home Construction and Safety Standards of 1976, from and after the effective date of this Chapter, shall be considered a nonconforming use of the land under the provisions of this Chapter; provided, however, that the owner occupying the existing manufactured home may replace said dwelling unit with a newer model manufactured home that meets the "HUD" cited above.
