To go even further, I think Jaymz has cleaned up in his place [this house is clean] meaning his head, his life, all the bad things like the addiction and stuff, and that he's going for the world now. He's becoming the Judge, The Jury and the Excecutioner of the world. I think it can be seen by "Court is in session and I slam my gavel down" that he wants to push his will through to make not only his house clean, but also the world outside of his life (=house)
