Overview

Welcome to 1221 Illini Dr, a spacious inviting two-story home offering 3,199 square feet of finished living space, finished lower level, beautifully shaded backyard, and freedom of a no-HOA neighborhood—all in a convenient O’Fallon location. The 0.221-acre lot feels manageable while still providing room for recreation, relaxation, and outdoor living. Important improvements add confidence to the home’s appeal: the roof was replaced in 2024 along with new gutters, soffit, fascia, and rear siding, and the water heater was also replaced in 2024.
