After World War Two, Viking FK took over as the dominating football club in Stavanger. SIF went on to play in lower divisions, and the club was also passed by FK Vidar (another club from Stavanger) in terms of league position and achievements in the 1980s.
With Roger Nilsen as manager, SIF was promoted to 2. divisjon in 2006. On 25 October 2008, SIF secured promotion to 1. divisjon for the 2009 season after winning their group in 2. divisjon, but were relegated back to 2. divisjon for the 2010 season. They were promptly relegated again, to 3. divisjon in 2010.
SIF currently play their home matches at SIF Stadion, which is located in Bekkefaret in Stavanger. Prior to the 2009 season in 1. divisjon, the stadium was upgraded with a new seated spectator stand and improved facilities for players and match officials. SIF Stadion has an artificial turf.
