The Red Barn in Estero Park has been a barn, a punk music venue, and a homeless shelter. It is now a storage shed for the Isla Vista Recreation and Park District. (The Old Campbell Barn is also red and nearby.)
On page 19 of this planning document, the County says: "The only known structure older than 50 years within the Estero Park plan area is commonly referred to as the Red Barn. Based on a review of aerial photos maintained at Santa Barbara County Planning & Development, the barn appears to have been located at its present site between 1938 and 1950...the barn meets criterion C for its distinctive type of architecture, which is rare in Isla Vista, and may be considered eligible for listing as a historical resource."
