No Clue. Go Ahead and light a fire, see who shows up and let the rest of us know. I know that you have to be at least 15 feet from any structure or property line. Common sense would tell you to look around and UP to see if any other things could catch on fire. You should also have a water hose standing by and if no hose at least three large buckets of water. Maybe I should also add that all open fire pits should be Outdoors. Yeah, I'm sure that is also important.
