Yup, it has been allowed for a long time. It falls under recreational burning and cooking fires as well. Recreational burns used to require a person to obtain a permit prior to lighting the fire. Essentially the only thing allowed without permit was a "cooking fire", which in all reality could be a bonfire as long as you had a pack of hot dogs next to it. In 2016, I believe, the county eliminated the need for a permit, however individuals still needed to follow the rules that were previously outlined for the permit.

I want to preface this by saying I realize you mean "could" as in "is allowed to", but for some reason I thought you meant "Huh, I didn't know wood burns."
