If a lawful use involving individual structures, or of a structure and land in combination exists at the effective date of adoption or amendment of the Zoning Code that would not be allowed in the district under the terms of this Zoning Code the lawful use may be continued so long as it remains otherwise lawful, subject to the following provisions.
(a) No existing structure devoted to a use not permitted by this Zoning Code in the district in which it is located shall be enlarged, extended, constructed, reconstructed, moved, or structurally altered except in changing the use of the structure to a use permitted in the district in which it is located.
(b) Any nonconforming use may be extended throughout any part of the building which was arranged or designed for the use at the time of adoption or amendment of this Zoning Code, but no nonconforming use shall be extended to occupy any land outside the building.
(c) A nonconforming residential use in a business district shall be permitted to continue as if they were in a residential district. The use must comply with the requirements of an R-1 Residential District. However, the use shall not be expanded into a combination business and residential use. Before the building is altered to be used for a business, the State Building Code, Fire Code, and all other applicable codes must be met. (Ord. 2017-18. Passed 5-2-17.)
