The Keerl–Decker House is an excellent example of Neoclassical architecture and the historic home remains a landmark in Mason City. The home was built around 1902 by Irving Keerl, who served as the Clerk of Courts for the county and also helped establish the Iowa State Bank of Mason City. Between 1919 to 1965, the house belonged to the Decker family, who ran a food processing company called Decker Meat Packing Plant, which is now operated by ConAgra Foods. The most notable feature of the house is the grand, two-story portico with fluted Ionic columns and decorative garlands. The house operated for many years as a bed and breakfast and was added to the National Register of Historic Places in 2002.


The Keerl-Decker House was built prominent local figure Irving Keerl around 1902. It was later occupied by the Decker family, who operated the Decker Meat Packing Plant, which was the city's largest employer during the Great Depression.

Plant, Sky, Building, Property

Irving Keerl grew up in Mason City. When he was sixteen, he dropped out of school to work as a postal clerk for his father, who was the postmaster. As noted above, Keerl eventually became the Clerk of Courts. At the Iowa State Bank, he worked as a cashier. He was also active in local civic affairs and in the Mason City Commercial Club. It is unclear how long Keerl owned the house.

Jay Decker bought the house in 1919. Decker's father, Jacob, established a meat packing plant in Chicago with a partner in 1892 and three years later, founded another plant in Mason City. Decker started working at the plant in Chicago after graduating with a business degree from Bryant & Stratton Business College. He moved to Mason City to work in the new plant in 1899 and served as vice president from 1920 to 1921 and president from 1922 to 1935. He and his wife, Angie, had three children who grew up in the house.

In 1975, the house was converted into a restaurant and a new kitchen wing was added. The restaurant operated at least through 2002 when it was added to the National Register of Historic Places. The property has been home to the Decker House Bed & Breakfast since 2011, but like many historic homes that are part of the hospitality industry, the global pandemic has led to uncertainty.
