Historic Redevelopment Opportunity – O'Neill Block | Dubuque, Iowa The O'Neill Block presents a rare 18,288 SF mixed-use redevelopment opportunity in the heart of Dubuque’s Old Main Historic District. Seller will consider flexible financing options, including a potential land contract, for qualified buyers. The property features two commercial spaces on the main floor, including a 4,062 SF restaurant/bar with a 6,092 SF finished lower-level bar previously operating as 1st & Main, along with a 2,031 SF bar/retail space formerly known as Esther’s Lounge (spaces are part of the sale but could also be leased). Site also offers a 1,428 SF outdoor patio. These spaces could continue as hospitality venues or be converted into office, retail, or other commercial uses. The upper two floors offer more than 12,000 SF of redevelopment potential, ideal for apartments, condominiums, boutique offices, or creative workspaces, providing a true blank slate for a transformative mixed-use project. Located within the Dubuque Opportunity Zone, the property may qualify for Historic Tax Credits, Tax Increment Financing (TIF), and City of Dubuque housing and façade incentives. The building sits in the center of major downtown investment, including the new John and Alice Butler College of Osteopathic Medicine developed by the University of Dubuque, expansion of the Dubuque Museum of Art, and continued redevelopment in the Historic Millwork District. This site is in extremely close proximity to the Five Flags Center and nearby hotels including Hotel Julien Dubuque and Holiday Inn Dubuque/Galena, the location benefits from strong tourism, event traffic, and a growing downtown residential base. Positioned just one block from the Highway 20 / 61 / 151 corridor, the O’Neill Block offers outstanding visibility and access, making it one of the most compelling historic redevelopment opportunities in downtown Dubuque.
