Ball continued to build on his burgeoning experience and growth and at the age of 29, purchased the American Apartments at NW 21st and Johnson Street. Located in the same historic Nob Hill neighborhood as the Sara Ann and Robert Daniel Apartments, The American is listed on the National Register of Historic places. It is a 39 unit, 6 story, building with brick veneer. 
Ball created a preservation plan as required by Federal and State regulations in order to rehabilitate this historic treasure. This entailed learning the rules and guidelines required to successfully navigate the historic renovation process. Rather than hire a professional consultant, Ball worked with the State of Oregon Preservation Office and learned the ins and outs of the program so he could build the necessary skill-set to become a leading historic property developer. Ball used his crew of craftsman and methods from his previous buildings to successfully renovate the property while carefully managing extensive building, historic, and zoning requirements. He then took a step into an entirely new area of his career and completed his conversion of an existing property into condominiums. This required him to learn the complicated area of creating CC&Rs; including Disclosures, Declarations and Bylaws. Ball learned how homeowner associations are formed, managed, and ultimately turned over to new homeowners. He also began to build successful liability management systems that would be carefully expanded over the next decade of the Robert Ball Companies team growth. The condominium was successfully sold out in a 5-week period and Ball renovated his own unit that he would live in for 7 years and own for another 8 years (with another brief time to live in before finally selling his “NW Jewel.”)
