(c)        Use of tables

To comply with the setback requirements of this Section, a building at any height shall be set back at least to the depth of the setback line indicated on the applicable table.

For heights between those shown on the table, the depth of the setback line shall be interpolated.

Required depths of setback lines shall be rounded off to the next highest half foot.

The setback requirements apply only to portions of buildings above the maximum height permitted at the street line, so that required setbacks on the narrower street frontage of a corner lot shall apply only to heights above the maximum front wall heights permitted by the corner lot provisions of paragraph (b) of Section 81-262 (Maximum height of front wall at the street line).

(d)        Middle one-third rule

A building may penetrate beyond the setback line at any height if the penetration is confined to the middle third of the front lot line length and complies in all respects with the middle one-third rule as defined in Section 81-261 (Definitions).
