The use of land existing at the time of the passage of the ordinance codified in this title although such use does not conform to the provisions of this title, may continue upon such conditions as prescribed by the Planning Agency. After this ordinance becomes effective, and if such non-conforming use is abandoned, or is discontinued for a period of six months or more, subsequent use of the land shall be in conformity with the provisions of this title. The extension of a non-conforming use to a portion of a structure which was arranged or designed for the non-conforming use at the time the ordinance codified in this title becomes effective, shall not be considered an extension of a non-conforming use.

The conditions prescribed by the Planning Agency for the continued use of a non-conforming use must bear a substantial relation to the alleviation of a hazard to the health, morals, safety, or general welfare of the entire affected community and in particular that of surrounding inhabitants. Conditions may be prescribed including, but not limited to, those situations existing because of fumes, odors, glare, noise, smoke, dust, unsightly materials, or other objectionable factors. If, in fact, conditions are prescribed by the Planning Agency because of the continuation of the non-conforming use, the matter is to be reviewed by the Planning Agency no less frequently than two years and/or upon change of ownership.
