No existing building or premises devoted to a use not permitted by this Chapter in the district in which such building or premises is located, except when required to do so by law or order, shall be enlarged, extended, reconstructed, substituted, or structurally altered to increase its nonconformity unless the use thereof is changed to a use permitted in the district in which such building or premises is located, and except as follows:
(b) Enlargement: When authorized by the Planning Commission, nonconforming buildings may be enlarged as long as the building meets all minimal yard requirements in the district in which it is located.
Additionally, all such extensions shall not exceed 100% of the floor area of the structure existing at the time it became nonconforming. All such extensions on structures nonconforming because of use shall be made within five (5) years of becoming nonconforming. Extensions may be made on a lot adjoining, provided that such lot was under the same ownership as the lot in question on the date such building became nonconforming.
