RMH permitting in the PNW

Is there any information concerning the permit process for RMH in Spokane WA.? Or should I just "fly under the radar".
If there are permit process in place in other cities in the PNW I could maybe point my local building code guys in that direction and get something done here in Spokane.

Hi Kelly,   Have you seen this thread? Insuring-house-rocket-mass-heater
Perhaps there is something in there that can help you. It starts out as an old thread but there have been recent additions at the bottom.

Also, there is a segment on building codes in Portland Oregon that is covered in The Rocket Mass Heaters Builders Guide book. An excellent resource for all things rockety.
Well worth the purchase if your planning on building one.
