I'm in the Clark County Bee Keeeper Association, Been looking in the phone book, not sure what the laws would be under, General info for Vancouver is 360-696-8200. They might have a clue . There's a number for code inforcement ,not sure if you would want to stir that up . Several members have hives in and around Vancouver and I have heard of no problems. If your neighbors don't complain your good.
Might be better to just talk with the neighbors and do it, If theres a complaint you can move them. I'm about 8 miles out , you can put them here if you need to. Email me if the number dosn't fly. My wife put up the CCBk web page . If its the same one your talking about, its just a myspace account not a paid for web page. We are behind over here.
I'm not tense, Just terribly, terribly alert!
