Stop in for a cup of coffee

I am getting ready to pour another footing, slab for a storage building. Not large, just 10 x 12. What you can build here without a permit. I know of a guy with about 10 of these on his property, with a large tarp covering them all. Nice!! This last bout of covid has really sapped my energy.......But getting better.....no more symptoms, just the loss of sustained energy.....BUT getting better....Sucks...
surprised you can even do that. Pretty sure I need permit for anything with a foundation. Most sheds around here sit on blocks
