The Bates Building is a historic house in the Columbia-Tusculum neighborhood of Cincinnati, Ohio, United States.

[2] Constructed in 1865,[1] the Bates Building is a simple frame building with a gabled roof of shingles; it is three bays wide, and each side is a single bay.

A significant exception to the house's simple construction is the ornate front porch, which appears to have been built after the rest of the house; complicated beveled woodwork covers the pillars of the porch.

The eastern side of the house is otherwise the most distinctive part of the building; an outward projection on that side is the only exception to the house's rectangular shape, and included in the projection is a small oval window, which is the only non-rectangular window in the house.

It was one of seventeen Columbia-Tusculum properties included in a multiple property submission related to a historic preservation survey that had been conducted in the previous few years; most of the properties were buildings, but the Columbia Baptist and Fulton-Presbyterian Cemeteries were also included.
