Bolingbrook, IL Building Setbacks & Zoning: Setback Rules (2026)

Bolingbrook's zoning ordinance, chapter 54, sets yard setbacks separately for each residential zoning district instead of a single villagewide standard. In the R-1 single-family district, the most common single-family designation, § 54-117(d)(3) requires a 35-foot front yard, 15-foot side yards, a 35-foot corner side yard, and a 40-foot rear yard, rising to a 60-foot rear yard on double-frontage lots. The E-R estate residence district, reserved for the largest lots, needs more room: a 35-foot front yard, 20-foot side yards, a 35-foot corner side yard and a 45-foot rear yard under § 54-116(d)(3).

The denser R-2 district relaxes the standard to a 30-foot front yard and a ten-foot side yard under § 54-118(d)(3). R-3 permits alternating 25-foot front yards, provided no two 25-foot front yards sit next to each other and the applicant proves the adjacent lots keep the full 30-foot yard, alongside an 8½-foot side yard, under § 54-119(d)(3). R-4, the attached single-family low-density district, uses a flat 30-foot front, side and rear yard for all residential structures under § 54-120(d). Schools face larger setbacks in every residential district: a 50-foot side yard and a 75-foot rear yard in R-1, R-2 and R-3 alike.

Under § 54-79, even where a recorded subdivision plat shows a smaller building or setback line, the minimum yard required by the applicable district section still controls.
