Columbia Avenue Historic District is located in the central part of the city of Davenport, Iowa, United States.

The double-house, or duplex, was popular in the city throughout the 19th century and were designed in the same styles as single-family dwellings.

Larger apartment blocks of three to five floors were built in and around the city center for middle and upper-middle class households around the turn of the 20th century.

[3] The apartment complex centered on Columbia Avenue was begun in 1930 by Mclnnes Brothers, a local contractor and developer.

Otto Behrens and John F. Steffen stepped in and completed the buildings begun by Mclnnes Brothers.

Eight of the buildings face both sides of West Columbia Avenue, which runs through the middle of the district between Harrison and Ripley Streets.

Others have hipped roofs with dormers and a flat facade, or a projecting central bay that terminates in shallow gables with partial returns.
