Riverfront Apartments, Residential building in Toledo, United States

Edge21 Apartments, formerly Riverfront Apartments, is a 21-story, 289 ft (88 m) building at 245 North Summit Street in Downtown Toledo. Designed by D. H. Burnham & Company of Chicago and built by The A. Bentley & Sons Company, it has a concrete and steel frame with a stone facade. Converted to apartments in 1999, it contains 41 one-bedroom, 51 two-bedroom and 8 three-bedroom units.

The 21-story tower was built in 1912-13 for the Second National Bank at the southwest corner of Summit Street and Madison Avenue, designed by D. H. Burnham & Company of Chicago with The A. Bentley & Sons Company as general contractor. Named the Second National Bank Building, it became the Toledo Trust headquarters from the 1930s until 1981, when the bank moved into a new triangular granite and glass building across Summit Street. Eyde Co. bought it in 1998 in a $4.5 million package with the Tower on the Maumee and the adjacent garage, then converted the offices into apartments in 1999.

The building's successive names record its uses: Second National Bank Building until the bank merged with Toledo Trust, Toledo Trust Building from the 1930s to 1981, Riverfront Apartments after the 1999 conversion, and Edge21 Apartments since January 2023. The 1999 conversion created 41 one-bedroom, 51 two-bedroom and 8 three-bedroom apartments.

The building stands at 245 North Summit Street, on the southwest corner of Summit Street and Madison Avenue in Downtown Toledo. It is a 21-story tower of 289 ft (88 m), currently the fifth-tallest in the city. The property is managed by DMG Rentals.

The building was sold in 1998 for $4.5 million as part of a package that also included the Tower on the Maumee and the adjacent parking garage. After conversion in 1999 it held 41 one-bedroom, 51 two-bedroom and 8 three-bedroom apartments. In January 2023 it was bought by Edge 21, LLC and renamed Edge21 Apartments.
