Laurens County, SC Building Setbacks & Zoning: Setback Rules (2026)

Table 10.A.6 of Laurens County Code § 33-91 sets the setback yards that apply to conventional single-family detached subdivisions in the unincorporated county, and the front yard varies by the street classification the Laurens County Public Works Department assigns to the road the lot fronts. A lot on a residential street needs a minimum 30-foot front yard, a lot on a collector street needs 40 feet, and a lot on an arterial street needs 50 feet. Side and rear yards do not vary by street class: every lot needs a minimum 10-foot side yard for the primary building and a minimum 10-foot rear yard, while a corner lot's side yard along its second street frontage must be 30 feet for all street classifications.

Section 33-91 also fixes how the front setback is measured where sidewalks exist, from the edge of the sidewalk closest to the building, and it puts the burden of applying the correct number on the subdivider, who must place the applicable setback lines in the property's restrictive covenants before lots are sold, with the Public Works Department responsible for classifying each street. Cul-de-sac lots get their own width rule, a minimum 30-foot lot width measured at the right-of-way edge, rather than the 75, 100, or 120-foot minimum lot widths that otherwise apply by water and sewer service type.

None of these setback numbers apply inside Laurens, Clinton, Gray Court, Cross Hill, Waterloo, or the Fountain Inn city limits, each of which sets its own zoning and setback rules.
