The purpose of this Section 14-16-6-8 is to regulate land uses, buildings, lots, signs, and site features that were legally established, but that do not conform to the requirements of this IDO due to some action of the government (collectively "nonconformities"). These regulations are intended to reduce or eliminate over time any nonconformity that does not meet the regulatory standards of the IDO and/or the goals of the ABC Comp Plan, as amended, and that creates adverse impacts on the surrounding area or the city.
