(a) Specific purposes of this chapter include:
(1) Preserving light and air, and avoiding congestion in Residential zoning districts;
(2) Ensuring setbacks, which provide a reasonable relationship between residences;
(3) Promoting streetscapes that are consistent with the intended character of different commercial and mixed-use zones;
(4) Controlling the overall building bulk and lot coverage to help define the character of different zones; and
(5) Promoting a reasonable building scale that is consistent with the function of commercial areas and the character of surrounding neighborhoods.
(b) General Provisions.
(1) Unless otherwise noted, building and structure height is measured as prescribed under definitions for maximum structure height or maximum building height and grade as applicable.
(2) On a corner lot nothing shall be erected, placed, planted or allowed to grow more than two and one-half feet in height within the triangular area formed by the street lines of such corner lots and a straight line joining points along said street lines 10 feet distant from the point of intersection.
(3) On any lot with more than one street frontage, only that lot line from which primary access to the property is derived shall be considered the front lot line. All other frontages shall be considered side or rear lot lines depending on which definition they most closely adhere as determined by the zoning official.
(4) Unless otherwise provided in this title, any structure that is exempt from the requirement to obtain a zoning permit per KGBC 18.90.020(b)(2) may be placed within the setbacks.
(5) Lot lines that separate the lot from salt water shall have no required yards.

a. The width of the eave or overhang shall not exceed 24 inches in width; and
b. The eave or overhang may not conceal any habitable space.
(7) Open, uncovered decks providing required off-street parking or access to required off-street parking may be built in required yards.
(8) Addition Extension Setback Exception. Either a front, side, or rear required yard setback for an addition to a preexisting structure shall be reduced by 20 percent; provided, that the axis of the addition is congruent with the axis of the preexisting structure. The minimum setback provided for under this exception is three feet.
(9) Addition to Preexisting Nonconforming Structure Setback Exception. Required yard setbacks for additions to preexisting nonconforming structures shall be reduced to the existing minimum setback; provided, that the addition does not increase that portion of the improved structure within the setback required by the zoning district by more than 50 percent.
