Beginning January 1, 2016, Texans with a handgun license will be allowed to openly carry their handguns. Churches in Texas may prevent handgun license holders from carrying handguns inside church buildings as long as the church gives proper notice. Each church may decide for itself whether to allow:
Both open and concealed carry of handguns
Concealed carry of handguns but not open carry
Open carry of handguns and not concealed carry
No handguns regardless of whether they are carried openly or concealed
A church does not need to take any action if it wishes to allow handgun license holders to conceal carry or open carry in church buildings. If permitting handgun license holders to conceal carry or open carry on church premises is a cause of concern to your church, Texas Penal Code Sections 30.006 and 30.007 provide clear rules for notifying handgun license holders that your church is a gun-free zone or concealed carry only.
In order to provide notice that a church prohibits either concealed carry or open carry the church must provide written communication to gun license holders. This written communication may be done in one of two different ways. Either churches may provide notice on a document that is handed out to all members and guests as they enter the building (e.g. a church bulletin or worship guide) or churches may post a sign on the property.
If the church chooses to notify license holders by posting a sign, the sign must be in both English and in Spanish, appear in contrasting colors with block letters at least one inch in height, and be displayed in a conspicuous manner clearly visible to the public. Regardless of whether a church chooses to provide notice through a document, sign, or both, the language for the written communication must be identical to the following:
