I believe you are incorrect here. There's no "permission" mentioned in the law. You need to own or control the property to carry there unlicensed. You can't "grant" permission for something that is against the law, even on your own property. Hunting or shooting on your property is a different situation, as they are defined as exceptions to 46.02, but you can't just give someone permission to carry on your property if they don't otherwise have a CHL or meet the other specific conditions of the law.
Below are the highlighted pertinent sections regarding people who are not LEOs or commissioned security guards. There is no mention of giving permission or consent to anyone to carry on your own premises. You must own or control the premises.
