Searching, it's mentioned in Chapter 58 that Irregulars open the door themselves (of their own will), and again in Vol. 2, Chapter 27, but I don't think that it really supports the importance that some readers have attached to it. The most important part seems to be what's mentioned in Vol 2, Chapter 27:  Irregulars are "free from all the contracts of the tower" because they come from the outside.

(This also emphasizes that the important thing about an Irregular is that they come from outside the tower:  "According to the contract, the inhabitents of the tower cannot kill Zahard."  Baam's Irregular status, as SIU confirms in that chapter's notes, is what makes it possible for him to do that.)
