What does your acreage and zoning ( if anything ), allow?
When I moved to my current location post divorce, as an FFL of 20 years at that point, I had a pretty loyal customer base who didn't want to see me go out of business.
I took a shed that was on the new property, trenched power and alarm to it, had customers who came over and we finished off the interior and installed security elements, etc.
I had to get a variance from the village to operate, and I cant have commercial signage, but I neither want nor need that.
The set-up passes muster with the ATF.
Its the best of both worlds; its "home-based" ( sorta ) without BEING "home based"
Its separate from the house so that avoids a whole lot of issues.
The down ...and up ...side has also been that I am always available when those people who want to come by at any time of the day or night want to do so.
That wasn't really an issue until this past year when Covid became a thing and word got around that I was the only FFL with a reliable amount of ammo on the shelves.
Some of the stuff that's been going on in that regard has me thinking hard about pulling the plug sooner rather than later. Too many people are losing their minds over the various panics, and its resulting in the whole thing being less and less fun.
Someone called me this morning at 2 AM, and its not the first time.
None of my older long term customers would have done that......
