The Society owns two Ripon houses, including one with a barn. The older of the two is the Pedrick-Lawson House which was placed on the National Register of Historic Places because of its unusual grout-block construction. Built in the 1850s, it is partially restored as it might have looked during the Civil War era. The barn is used for storage and exhibits including farm tools and equipment. A Victorian garden with markers identifying its various plants and flowers has been developed on the property. The newer of the two houses, the Pickard House, was built during the 1870s and has been remodeled and furnished to resemble a modest middle-class home in the early part of the 20th century. It contains the Society's archives, library, meeting room, and museum for both permanent and temporary exhibits. The museum collection includes Victorian and early-20th-century furniture and furnishings, men's and women's clothing, quilts and coverlets, tools and equipment for various trades and occupations, dishes and glassware, and works of art by Ripon artists. Special collections of such items as local business and professional records and artifacts, wedding dresses, children's toys, games and dolls, and war memorabilia are featured in our permanent and changing exhibits.

The houses offers exhibits and tours; the society offers research library access and educational and recreational programs.

The Society operates two house museums. The 1872 Lee House was home to Dr. Norman Lee, one of Junction City's first doctors. It was originally located in Lancaster and was moved to its present location in the late 1800s using logs and a team of horses; it now displays photos, furniture, tools, and clothing from Junction City's past. The 1871 Pitney House belonged to Mary Pitney (1891—1995), a school teacher, published poet, painter, world traveler, and humanitarian. Born and raised in this house, she lived the later years of her life here; today, it is being restored and features a room devoted to Danish historical artifacts from Junction City's first settlers, a cutaway of the home in the kitchen so visitors can see how buildings were constructed in that time period, and Mary's original furniture in the living room. Next door to the Pitney House is the first jail, built in 1873.

The houses offer exhibits, tours, and occasional recreational and educational events.
