Where an existing building is nonconforming with respect to setbacks, expansion of said building within the plane of the furthest intrusion shall be permitted; provided, that the nonconformity with respect to the distance of the setback is not further increased. Such expansion shall not be considered to be increasing the degree of nonconformity pursuant to section 17.13.060 of this title. The following exceptions apply:
A. In no case may expansion occur that results in a setback of less than six feet (6') from property lines abutting other private property.
B. Any wall, as measured from the highest point, including any gable or peak in a direct vertical line to record grade, shall have a setback of one foot (1') for every two and one-half feet (21/2') of wall height (see section 17.04M.090, diagram 1 and table 2 of this article), but not less than six feet (6') from property lines abutting other private property, regardless of underlying zoning.
C. No roof overhangs, fire escapes, chimneys, bay windows or other features, which are subject to section 17.07.010, "Supplementary Yard Setback Requirements", of this title, shall have a setback less than five feet (5') from property lines abutting other private property. (Ord. 1191, 2015)
