Iredell County, NC Building Setbacks & Zoning: Setback Rules (2026)

Table 2.5, Dimensional Requirements in the R-A District, sets a single-family lot at a minimum 20,000 square feet with 100 feet of lot width, and requires a 35-foot front setback, 15-foot side setback, 35-foot rear setback and 25-foot corner-lot setback; a two-family lot needs 15,000 square feet and 110 feet of width but carries the identical yard setbacks. Table 2.11 for the R-20 Single-Family Residential District uses the same 35/15/35/25 front/side/rear/corner setbacks on a 20,000 square foot lot (15,000 square feet where public water is available), showing the front, side, rear and corner figures repeat across the county's core residential districts even as minimum lot size changes.

Section 2.2.6 defines how a setback is measured: from the property line or street right-of-way line to the nearest part of any building or structure, excluding uncovered porches, balconies, decks, chimneys, eaves, roof overhangs, and similar features that project no more than three feet into the required yard. Section 2.2.4 allows a reduced front setback on an older, already-developed street: where the average setback of existing buildings within 100 feet on either side of a lot is less than the district minimum, a new dwelling can match that lower average, but never less than 10 feet from the right-of-way line. Accessory buildings and structures follow a separate standard under the Chapter 3 performance requirement R1: they cannot sit in front of the principal structure's front building line, must stay at least 10 feet from any non-street property line, and any accessory structure over 2,000 square feet needs a 30-foot setback from the property line.
