I've been shut down twice by the Dept of Environment for backyard work - once for spray painting a truck box outside and the other time for sanblasting behind my garage. I'm on the edge of the woods but houses are near by. The neighbour reported me.

Had to build a paint booth inside my garage and install filters. Built an outside enclosed booth for blasting. A pain for sure but I got small kids too that play outside so all for the better.
