It is located at 4 East Bay Street, and was designed by architect Henry John Klutho. On April 17, 1980, it was added to the U.S. National Register of Historic Places.

Following Jacksonville's Great Fire of 1901, the building was the first multi-story structure built in the barren downtown area and the first design by Klutho in Jacksonville. Construction began on a five-story building, but demand for office space spurred the addition of a sixth floor. As the name states, Dyal–Upchurch was a Georgia investment company that moved to Jacksonville after the fire. Frank Upchurch had interests in turpentine and lumber, while Benjamin Dyal owned a sawmill. The company ceased business in Jacksonville after 1924.
The Atlantic National Bank was founded shortly after the Dyal–Upchurch building opened in May, 1902 and was located on the first floor until their own building was constructed in 1909. Other tenants have included an office of the National Weather Service, a regional office for the Connecticut General Life Insurance Company, law offices and a financial advice company.
When the building was added to the National Register of Historic Places in 1980, it became eligible to use rehabilitation tax credits when restoration work was performed in 1981, the first building in Jacksonville to do so.
In May, 2002, the city established the Downtown Historic Preservation and Revitalization Trust Fund with $7 million to assist companies that purchase and restore old buildings. The fund could pay up to half the cost of exterior work and one-fifth of interior work with a $1 million cap per building. That was sufficient incentive for Husk Jennings to begin a $1.72 million restoration of the rest of the building, for which the city kicked in almost $340,000. 
Cameron Kuhn, a commercial developer from Orlando, Florida, purchased the building in December, 2005 for $4.5 million, but defaulted on the mortgage when his company declared bankruptcy in 2008. The Dyal–Upchurch building was repossessed by The Jacksonville Bank in January, and sold on February 28, 2009 for $3.73 million to A. Duda & Sons of Oviedo, Florida.
