From Vacant High-Rise to Vibrant Housing and Retail

The Centre City Building will include 137 residential units at a range of affordability levels. The unit mix includes studio, one-bedroom, and two-bedroom layouts designed to support a range of household types. Many of the units will include historic features preserved through the development process, including terrazzo floors, transom windows, and more. 

Residents will have access to a robust set of amenities, including a fitness room, resident club lounge with kitchenette, bike storage, package room, and leasing office, along with enhanced security features and direct access to structured parking. Located within a mixed-use environment, residents also benefit from on-site ground-floor retail and a pet-friendly living experience. 

The rehabilitation of the Air City Garage will restore a critical downtown asset, delivering 390 structured parking spaces to support the Mainline development. The garage will serve residents across the mixed-income residential units, additional affordable housing on the block, the Greater Dayton Regional Transit Authority, and ground-floor commercial tenants, and will also help alleviate valet parking needs from the adjacent Hilton Garden Inn, providing reliable access for both daily use and visitors. 

By consolidating parking within a central, rehabilitated structure, the project strengthens the overall functionality of the development while supporting increased residential density, retail activity, and long-term use of the surrounding buildings. 

The project will deliver four ground-floor retail spaces totaling nearly 8,000 square feet, creating a mix of innovation-focused and neighborhood-serving uses. Anticipated Tenants include EC Innovates, a 1,332-square-foot extension of the Dayton Arcade Innovation Hub supporting startups and small businesses; a 1,995-square-foot café bringing daily activity to the corridor; and Model Construction, a 2,080-square-foot Dayton office operated by The Model Group, the developer overseeing the Mainline redevelopment and operations. The project also plans to house a locally operated fresh food market and café concept, providing residents with convenient access to healthy, high-quality food options in a neighborhood that has historically faced limited access to fresh and nutritious choices. 

Together, these tenants represent a range of uses that support entrepreneurship, workforce activity, and everyday neighborhood needs, helping activate the street level while reinforcing economic development in downtown Dayton. 

Located adjacent to Wright Stop Plaza, an area that has faced persistent perceptions of crime and disinvestment, the project is positioned to help shift conditions on the ground. The redevelopment introduces new residential density, consistent foot traffic, and active ground-floor uses, all of which contribute to a safer and more active streetscape. In parallel, the project incorporates enhanced security measures and building design features intended to directly address safety concerns noted in the surrounding area. 

The investment also reflects the continued momentum generated by the nearby Dayton Arcade redevelopment. As one of the next major projects in the corridor, Mainline reinforces growing market confidence and contributes to a broader pattern of reinvestment that is reshaping downtown Dayton’s core.
