The former Hamilton Air Force Base is also located in Novato, but was decommissioned in 1974 and designated a Historic District in 1998. After lying stagnant for many years, major renovations were pushed through by then-mayor Michael DiGiorgio. As of 2008 the base has largely been redeveloped into single-family homes. The former hangar buildings were gutted and redeveloped into two-story office buildings; tenants include 2K Sports, Sony Imageworks, Visual Concepts, The Republic of Tea, Toys For Bob, and Birkenstock Distribution USA.
