The Independent Order of Odd Fellows Hall contributes to the Nevada City Downtown Historic District which was added to the National Register of Historic Places in 1985. The following description of the IOOF Hall is excerpted from the NRHP nomination for the district:

Designed by William Bettis, this two-and-one-half-story brick fraternal hall houses a retail shop on the street level facing Broad Street and another in the two story extension that goes back to Spring Street. Lodge halls and offices are on the second floor.

Originally, six pillars at the Broad Street curb supported a canopy over the sidewalk. The five windows facing the street on the second story were arched and of identical size and were framed by six pilasters which extended to the cornice above. An ornamental medallion was placed above each arched window. The new entry, the large plate glass windows at street level, and the larger windows on the second story front were completed in April, 1904.

The Independent Order of Odd Fellows (I.O.O.F.) is an altruistic fraternal organization derived from the similar English Oddfellows service organizations which came into being during the 1700s....Although in Britain the Odd Fellows tended to meet in pubs, in the U.S. the lodges often built their own facilities. Many of these are now on the U.S. National Register of Historic Places....
