3309 Roosevelt St.
Built by Pablo Ramirez in 1918, this house is closely associated with the growth of Carlsbad’s Mexican-American community. During the Mexican Revolution in 1916, many Mexicans immigrated to the U.S. The majority who settled in Carlsbad formed the backbone of agricultural development in the city, forming a micro-community called Barrio Carlos. Pablo Ramirez, who built this house, was one of the first settlers. Alex La Betta purchased much of the land in this neighborhood, building small one- and two-room homes. Without electricity or indoor plumbing, each sold for $500. Several of these original structures still remain.
