Lars Vilks, from Nyhamnslage in southern Sweden, was not at home during the attack and no injuries have been reported.
According to police reports, attackers smashed windows and left plastic bottles filled with gasoline behind them. A small fire broke out, but is thought to have fizzled out by itself. There were no suspects.
Vilks did not immediately answer phone calls seeking comment.
Vilks has been subject to several threats since his 2007 sketch of Muhammad, including from al-Qaeda. Earlier this week he was assaulted by a man while giving a lecture at a university.
