When I started to build my new shop 13 or so years ago, I had already established a relationship with the local code inspector to prevent surprises with fire codes and such. But I found out the hard way he retired before I finished, when the new guy showed up for the final inspection. I was scared, but the first words out of his mouth were, Wow a side draft forge.... it turned out he was an apprentice smith when younger. so he understood what was a fire risk and what was not, It passed just fine.
