Which Code In Washington State?

[winesalot]

Which code is followed in Washington State? Is this a County specific answer or does the entire state follow the same code? Also, in the electrical world there are the Ugly's series of reference manuals. Is there something similar in the plumbing world? Thanks in advance.
