I'm going to give you the benefit of the doubt and believe that you are not being purposely misleading. Florida statute 790.06 reads as follows:
{SNIP}
This statute is typical of those in other states that grant concealed carry permits. It specifies -- just so there is no confusion -- where a concealed carrier may NOT carry their firearm. It tells you where you may NOT carry, not where you can.
To read into this statute that because the private property of others is not specifically precluded that it "authorizes" you to carry onto other people's private property is a sophomoric misreading. By your understanding, this statute would allow you to carry into my home even if I said you can't, and I promise you that is not the case.
Exactly, 790.06 (plus a couple other statutes related to schools prisons/jails, etc) tell us where it is illegal to carry a concealed firearm or weapon (when carrying that firearm or weapon under authority of one's CWFL). The rules of statutory construction therefore tells us that
everywhere else is legal. If this was not the case, anyone (not living there) carrying concealed at your home would be violating the law - with or without your 'permission'.
As I've explained a quasi-public property owner's only recourse is to ask someone to leave after they have already entered onto/into your property. A personally communicated request to leave. Florida law has no provisions for any type of 'conditional entry'.
By your understanding, this statute would allow you to carry into my home even if I said you can't, and I promise you that is not the case.
Well, we were talking about quasi-public property, so let's try it this way: You are having a open house while trying to sell your home so you post an "Open House" sign in your front yard. The is legally an invitation to enter.
You also put up a sign that says "No firearms permitted inside." It is perfectly legal for someone to ignore that sign. If you discover they are armed your only recourse is to revoke their invitation and request the individual to leave. Only his failure to do so will place him in legal jeopardy.
As for this part:
If personally communicated to someone as they were walking into your house, that might (doubtful but possible) be sufficient to satisfy the case law requirement because it was personally communicated to the individual, however the notification requirement is specifically related to trespass, not 'conditional entry' requirements like "No shirts, no shoes, no service" signs carry no legal weight. Just like "No firearms" signs.
So in your scenario you tell someone they cannot come into your house with a gun. Let's say by standing at the door saying "No firearms inside".
They do anyway - concealed.
Sometime later, you find out.
What are you going to do?
1) Call the police and tell them?
2) Or are you going to tell the individual to get out?
In #1 the police are not going to make an arrest because the individual broke no laws.
In #2 you just gave the individual a personally communicated revocation of their invitation. At this point if they refuse to leave, they are statutorily trespassing. Now as I've already said, most LEA policies do not call for an arrest in that situation either. They will simply help you remove the individual from your property and of course you will have already told them not to return.
There is no case law in Florida that addresses this 'conditional entry' that you are suggesting.
Your desire to not have firearms on your property does not make it illegal to do so. (Again unless you tell someone to leave and they do not.)
This is not to say you cannot prevent anyone from entering your property, you certainly can. All I'm saying is that there is no legal jeopardy for ignoring a "No Firearms' sign.
In Florida, when you invite someone in you have just invited them in with anything they may choose to bring with them. Unless of course you set up metal detectors, bag checks, searches, etc. But these may only occur once the individual has already entered your property - even if only by a few feet.
