setback or how the structure qualifies for an exemption. If buildings on separate lots are attached or connected at a common lot line, the solar setback standards apply as if the buildings are a single building on a single lot composed of both lots. (See Figure 9.2795 Solar Setback Standards, Figure 9.2795(2) Shade Point Height (SPH) Measurement, Figure 9.2795(2)(a) R -1 Solar Setback Calculation, and Figure 9.2795(2)(b) R -2 Solar Setback Calculation.) (a) Solar setback for R -1 zone The solar setback of the shade point shall be greater than or equal to the following formula: SSB = (2.5 X SPH) + (N divided by 2) - 82.5 Where: SSB = Solar setback (the shortest horizontal distance between the shade point and the plane of the northern lot line). SPH = Shade point height (Reduce this dimension by 3 feet if the shade point is a ridgeline between 45 degrees east or west of true north.) N = North -south lot dimension. Maximum allowable "N" for purposes of calculating the solar setback shall be 90 feet. The following table, which accurately applies the formula, can be used to determine compliance with the solar setback standard.
