I once obtained a utility pole as they were being replaced with new ones near my home. My intent was to use it to try my hand at hewing. The chunk of pole I got was only about 12' long, and had been exposed to the weather for decades. I stored it in my garage for a couple of weeks before I got around to taking an axe to it. When I went out to the garage, I was surprised to find that the whole building really reeked of creosote. This, in spite of the fact that the garage involved was not a "tight" building and there was only one piece of weathered material in it. I would imagine that it would be hard to stomach the strength of that odor in a house framed with creosoted material. Of course, if you are talking about untreated poles, none of the above would apply.
