I'm interested to know if anyone has a link or information in regards to chicken coop structure regulations and what might be the distance between residential homes for this area. From what I understand this area is not ordinanced for chickens. But there seems to be some regulations for coops structure and distance as I noted above. I gave a call to Dept of Land Use and all I get as an option is to leave a message with the person with this information. Called yesterday as well, but yet no call backs... I'm in the unincorporated Washington County area of Tigard, the West side of Bull Mountain.
