That should be negotiated between you and the owner of the site, and will surely depends on the deal between the two of you? It will be unethical, imho to just do it without their agreement. Sometimes, when I charge a special rate or even when I build a site free of charge, I do it with my name in the footer area, but the clients knew this from the beginning and agreed to it beforehand.
In your case, just get their permission and if agreed, you do it.
