Pursuant to section 10-3-3 of this title, upon application by a property owner or upon application initiated or required by the city, the city council, sitting as a board of adjustments and appeals, by majority vote, may determine that the nonconforming use of a lot or structure is lawful and issue a nonconforming use certificate to the owner. The board of adjustments and appeals may include in the nonconforming use certificate reasonable conditions governing the continued use of the lot or structure and may authorize accessory uses not currently on the property to be placed thereon in the future. A nonconforming use certificate shall not allow a principal use that did not legally exist on the property prior to the property becoming nonconforming. (Ord. 1198, 11-9-2009)
