I may have the wrong section of code however, this section may help:
76-10-511. Possession of loaded firearm at residence or on real property authorized.
Except for persons described in Section 76-10-503 and 18 U.S.C. Sec. 922(g) and as otherwise prescribed in this part, a person may have a loaded firearm:
(1) at the person's place of residence, including any temporary residence or camp; or
(2) on the person's real property.
I am at work and my reference materials, including Mitch Vilos book (4th edition) are at home. I am certain he references this there but am unable to do more at this time.
The section you quoted above also has nothing to do with business owners allowing others to conceal at work.
It only authorizes people to be able to carry a loaded firearm at their place of residence, including any temporary residence or camp, and on the person's real property.
I have Mitch's book, and it says nothing about allowing others to be able to conceal on property that is the business owners. Unless it is the business owner. At least not in the section quoted above. Page 77 in the book.
The only way around it, as far as I know, is to have a CFP. That way you can have a loaded and concealed firearm on you.
