Do “No Gun Signs” Have the Force of Law?
“YES”
Frequently Asked Question From MARGO Michigan Coalition For Responsible Gun Owners.
Q: Is there a specific design for the no gun allowed sign? Does the law say where it has to be placed at a business, such as on the door or adjacent window leading into the business?

A: There are no specifications for "No Guns" or "No Weapons" signs in Michigan law. Under the law, there are two ways for a CPL holder to know that guns are not allowed in a specific location. The first is the list of "Pistol Free Zones" (often colloquially referred to as violent criminal empowerment zones) that we must all memorize, which is part of the CPL statute (Pistol Free Areas).
The second is when the owner or lessor of any real property communicates to us that our guns are not welcome there. That communication must be reasonable in order to be effective. By reasonable, I don't mean polite. I mean that there is an effective means of communicating to us that we are not welcome so long as we are carrying our guns. This can be done with a sign, verbally, or in some kind of printed material.
For instance, if there is a reasonably-sized and located sign in a retail establishment indicating that guns or weapons are not allowed, that would constitute reasonable notice. If an employee of the same establishment actually tells you that you may not carry on the premises, that would constitute reasonable notice. If your employer has an employee handbook or some kind of printed guidelines, and includes a prohibition on guns and/or weapons, that would constitute reasonable notice.
If you choose to ignore any such reasonable notice, then you become a trespasser rather than a business invitee. Trespass can be punished as a crime and/or in civil court, and could affect your CPL licensing status.
