The building consists mainly of office space, which is largely occupied by its owner, Principal Financial Group. The lower three floors contain retail and restaurant space, including the 801 Steak & Chop House, and provide a connection to Des Moines' skywalk system. Other tenants include the law firms of McKee, Voorhees, & Sease; Bradshaw, Fowler, Proctor & Fairgrave; and Faegre Baker Daniels.

801 Grand's roof is made out of copper sheeting that was designed to form a green coating of verdigris over time, much like the Statue of Liberty. However, unlike New York City, the air salt content in Des Moines was so low that the desired oxidation process failed. The result was the copper turned a dark brown. Discussions on possible removal of the top layer of copper that would allow crews to purposely cause the oxidation process to create verdigris resulted in the decision to leave the roof as is.
