Thanks for all the replies. It will have a concrete floor and probably at least 3 feet in all directions around it so sounds like I should be ok. Thanks again. Once I start this project I will try to send some pictures.
I am going to build a shelter/shed for my 22 inch WSM. This will be built mostly from treated wood. What clearances should I keep away from sides and top of smoker so I don't have to worry about fire. I will be kind of a lean to off of my existing shed. Seems like every time I plan to smoke...
