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

Table 5-2 of the Unified Development Code, titled 'Table of Area, Yard, and Height Requirements,' sets minimum lot size, frontage and yard setbacks by zoning district and by which combination of well, county water and county or septic sewer service a lot has. For AR (Agricultural Residential) with well and septic, a single-family dwelling, manufactured home or family care home needs a 30,000-square-foot lot, 90 feet of frontage, a 30-foot front setback, 10-foot side setback and 25-foot rear setback; nonresidential uses in the same AR category need a larger 45,000-square-foot lot but the same 30-foot front, though a 30-foot side and 50-foot rear setback.

Footnote 5 lets the Administrator reduce a lot's side yard when the lot is narrower than the district minimum, but never below 10 feet, except in R-8 districts where the floor drops to 6 feet. Footnote 3 gives corner lots in residential districts with two intersecting streets a break, allowing the secondary front yard setback to be reduced by one-third. Minor projections get their own allowances under Section 5.5.1.C: uncovered stairs, porches and balconies may project into a yard but no more than 6 feet and no closer than 5 feet to a lot line, while architectural features like chimneys and eaves may project into a required yard if kept at least 6 feet from the property line.

Encroaching on a required setback, or building closer to a line than the table allows for the applicable district and service combination, is a Unified Development Code violation enforced under Section 3.4.2: the Administrator can deny or revoke the permit, issue a civil citation of up to $500 with additional daily penalties for uncorrected violations, and pursue Class 3 misdemeanor criminal charges.
