The Ramona Town Hall was listed on the National Register of Historic Places in 1994. It has also been known as Town Hall of Nuevo, and Barnett Hall. The Hall was built on two lots donated by Milton Santee, who as noted above headed up the Santa Maria Land & Water Company syndicate. Augustus and Martha Barnett donated the $17,000 "to the towns people of Nuevo, on Washington's Birthday, February 22, 1894." Ramona Town Hall was designed by architect William S. Hebbard, who later, with his partner, Irving Gill, produced San Diego's best architecture until its breakup in 1907. The building is one of the largest, and oldest, adobe structures in southern California. Photographs of William Hebbard and Ramona Town Hall may be viewed on this San Diego Historical Society page, and on the Ramona Town Hall website.
