Iredell County, NC Building Setbacks & Zoning: Structure Height Limits (2026)

Table 2.5, Dimensional Requirements in the R-A District, lists a Maximum Height of 35 feet for single-family homes, two-family homes and other principal structures alike, and Table 2.11 for the R-20 Single-Family Residential District repeats the same 35-foot cap. Section 2.2.5, Height Limitation Exceptions, carves out specific structure types from that district-by-district ceiling: public buildings, churches, temples, schools, hospitals, belfries, cupolas and domes not intended for residential purposes, or monuments, water towers, observation towers, power transmission towers, flag poles and similar structures, provided they meet the North Carolina Building Code and the airport hazard rules in Section 4.6. The ordinance also warns that some of those taller structures shall be subject to certain conditions set forth in the Performance Requirements to the Table of Permitted Uses even after clearing the general exception.

Accessory buildings do not get their own taller allowance: performance requirement R1 in Chapter 3 states that accessory buildings and structures shall not exceed the height limitation for the principal structure, tying every shed, detached garage or barn on a residential lot to the same 35-foot ceiling that governs the house itself. Specialty uses can be treated differently through the special use permit process; for example, wireless telecommunication towers are evaluated for height under a separate setback formula in performance requirement R61 rather than the district's 35-foot residential cap.
