§ 200-224. Additions and alterations to nonconforming buildings.

Nothing in this article shall be deemed to prevent normal maintenance and repair, structural alteration in or the reconstruction of a noncomplying building, provided that such action does not increase or extend the degree of or create any new nonconformity with regard to the regulations pertaining to such buildings or the lot upon which they are constructed (e.g., an undersized house, situated closer to the street line than now specified may have an addition on the back, provided that side and rear yards are not invaded), except that the floor area of a single-family house that occupies a lot that is smaller than the minimum lot area for the district in which the house is located may be increased by not more than 20% of the floor area existing as of the date of adoption of this Part 4, provided that all other provisions of this Part 4 are complied with. Yard reductions for such undersized lots may be permitted according to criteria established in § 200-225 of this article. This latter exception shall not apply to those lots in which an increase in floor area of a nonconforming building has occurred since August 15, 1975.
