Full Breakdown
LDC § 12-3-202 defines how front, rear, side, and street-side setbacks are measured from lot lines, and Table 12-3-301A (under § 12-3-301) sets the actual minimums by zoning subdistrict. In the NC 9 single-family district, the front and street-side setbacks are 20 ft., the interior side setback is 5 ft. (16 ft. total for both sides combined), and the rear setback is 20 ft. Other NC subdistricts differ. NC 2A requires a 50 ft. front and street-side setback, while NC 5 requires only 15 ft. front and 10 ft. side. Buildings within 50 feet of an NC, NI-8, or NI-18 district add one foot of setback per foot of height over 35 feet.
Violations & Fines
Building within the required setback without an approved variance or alternative-standard approval is a zoning violation; the City may require removal, relocation, or correction of the encroaching structure.
