231 E 1st Avenue A rare opportunity to acquire a well-located industrial property in Roselle, NJ. This 1, 600 SF flex/industrial warehouse offers a secure fenced yard, flexible zoning, and excellent access to major transportation routes. Built in 1947, this single-story masonry building features a 10' x 10' drive-in door and ~10 ft clear height, making it ideal for light manufacturing, warehouse operations, or conversion to a fabrication shop, showroom, or e-fulfillment micro-hub. The secure 50' x 125' fenced yard accommodates box trucks, reefers, containers, or grow-media drop-offs. With sub-5% vacancy in Union County for fenced-yard industrial product of this size, this is a virtually off-market opportunity.
