Founded in 1968, Sabadell B moved down to the last category in 1980. Nine years later, it returned to Primera Regional, only lasting nine seasons in the category. It eventually folded in 2003, and the first team subsequently established an agreement with CF Can Llong. In 2006, Can Llong merged into Sabadell's structure, and the B-team was refounded under the name of Centre d'Esports Sabadell Amateur-Can Llong.
The club switched back to the name of Sabadell B in 2007, and after achieving promotion to Segunda Catalana in 2010–11, the club promoted to Primera Catalana at the end of the 2012–13 campaign.[1]
On 14 June 2014, Sabadell B was promoted to Tercera División for the first time, after a 1–0 win against CF Sales Viladecans.[2]
