Lawfully existing or established buildings, structures and uses

A building, structure or use of land was lawfully established if it was in existence prior to the effective date of this chapter, or was established in conformance with the Zoning Ordinance in effect at the time the use was first established. A lot was lawfully established if it was of record or shown on a recorded plat prior to the effective date of this chapter. All other lots that were not lawfully established are not protected by this section. For the purposes of this chapter, the creation and/or the use of a parcel of land for a particular use which was legal at the time the parcel of land was created and/or so used shall not serve to create the lawful establishment or lawful existence of any use that was not legal at the time of creation and/or use of the land, regardless of subsequent changes in allowable legal use.
