Early years

Aviation in the area began in 1914 when Lincoln J. Beachey flew an airplane across Goleta Valley. Two years later the Loughead brothers, who later changed their name to Lockheed, established a seaplane factory on State Street (Alco Hydro-Aeroplane Company) and constructed a wooden ramp on West Beach to launch their planes. In 1928, Gordon Sackett and Royce Stetson landed a Hisso-powered airplane in a cow pasture near the corner of Hollister and Fairview Avenues and set up a flight school. That first airstrip marked the beginning of what was to become the Santa Barbara Municipal Airport.

As airplane manufacturing grew in the late 1930s the airstrip developed into an airfield. Western General set up shop and began producing Meteor airplanes, while Santa Barbara Airways' founder Frederick Stearns II built two additional runways and two large hangars. Stearns also installed the first radio equipment at the airfield.

As war approached the United States Government established a program to build 250 airports across the country on a cost-sharing basis with local governments. Thomas M. Storke secured Santa Barbara's enrollment in the program, and in 1941 groundbreaking ceremonies were held for the Santa Barbara Municipal Airport.

With the outbreak of WWII the airport became MCAS Santa Barbara (Marine Corps Air Station Santa Barbara) in 1942, an aviator training base for the U.S Marines. It was expanded further with the addition of many hangars and other buildings, and reverted to a civilian airport in 1946.

The original Spanish-style terminal building, commissioned by United Airlines in 1942 was designed by William Edwards and Joseph Plunkett, an architectural team whose work, including the Arlington Theatre and the National Armory, helped shape the Mediterranean style of the city.

Postwar developments

In 1947 the Santa Barbara Flying Club was formed to promote general aviation in the region.

Three runways are in use: 7/25 and two parallel runways 15/33. The airport originally had an additional strip: runway 3/21. The development of the University of California, Santa Barbara (to the southwest) and the construction of hangars in support of production of the Aero Spacelines Super Guppy (to the northeast) were factors in the removal of this runway. The Aero Spacelines hangars were later occupied by Tracor Aviation, a company that modified airliners.

Additions to the historic terminal made in 1967 and 1976 were removed and the original building was restored. It then was raised to meet modern flood plain regulations, and moved and incorporated into the new terminal. The aircraft parking ramp was redesigned, and a new loop road and short term parking lot were constructed. The new terminal building features many environmentally sustainable elements and is registered with the U.S. Green Building Council Leadership in Energy and Environmental Design (LEED). It was originally designed to feature four glass passenger boarding bridges and four hardstands, but due to decreased flight activity, three jetbridges were constructed with five hardstands.

An Airport Master Plan was prepared in 2017. In late 2019, the fourth boarding bridge was installed to replace a hardstand to help the airport cope with increased flight activity and upgauging. Relocation of the car rental lot in 2025 allowed all four jetbridges to accommodate mainline aircraft, up from two previously. Rental Lot expanded in size.
