ZSD Corp, founded in 2017 and headquartered in Chicago, is a privately held real estate development firm that specializes in new-construction, for-sale multifamily and condominium projects. The company oversees the full development process—from land acquisition, zoning, financing, and entitlements to construction oversight and sales/marketing. In 2025, ZSD acquired a River North parking lot to build a 149-unit rental development, reflecting a strategic expansion into urban infill projects. The company is recognized for its architecturally significant and locally focused approach to community-oriented housing. Positioned for growth in Chicago’s residential development market, ZSD remains privately held.
