Stefan Johannesberg from laut.de rated the album two out of five stars.[1] He found that Girls in the House lacked charisma but displayed "a few good approaches. Whenever fast-paced grooves dominate songs like the title track, the first single "Everyday Girl" or the straight "Riding On a Lovetrain", the vocals of the five young singers do not stand out in a negative way, but rather act as a nice-sounding accessory. There is simply not enough more."[1]
Girls in the House debuted and peaked at number two on the German Albums Chart in the week of 8 December 2003 – second only to Robbie Williams' Live Summer 2003.[2] In 2004, it was certified Gold by the Bundesverband Musikindustrie (BVMI) for shipments figures in excess of 100,000 units.[3] The album also reached number three on the Swiss Albums Chart and debuted at number 13 on the Austrian Albums Chart.[4][5] It was ranked 77th on the Swiss Albums year-end chart.[6]
