Executive Summary

Historic Downtown Dubuque Redevelopment Opportunity
The O'Neill Block presents a rare 24,000+ SF mixed-use redevelopment opportunity in the heart of downtown Dubuque’s Old Main Historic District.
The property features two turnkey bar/restaurant spaces on the main level, plus a finished 6,000+ SF lower-level bar. The upper two floors offer over 12,000 SF of redevelopment potential, ideal for apartments, boutique offices, or mixed-use residential development.
Located within a Dubuque Opportunity Zone, the project may qualify for Historic Tax Credits, TIF, and City housing and façade incentives.
The building conveniently located near the Five Flags Center, multiple downtown hotels including Hotel Julien Dubuque, and major ongoing investments such as the John and Alice Butler College of Osteopathic Medicine and expansion of the Dubuque Museum of Art.
With strong tourism, growing residential density, and major institutional investment nearby, the O’Neill Block represents one of the most compelling historic redevelopment opportunities in downtown Dubuque. Seller will consider flexible financing options, including a potential land contract, for qualified buyers.
