That is misinformation. If you want to post the statutory signs so that ignoring your signs is a crime, then they MUST be:
* in the statutory language;
* in contrasting colors with block letters at least 1 inch in height;
* in English and Spanish; and
* displayed in a conspicuous manner clearly visible to the public (AND under 30.07,
at every public entrance--though I think it is arguable that a 30.06 sign isn't conspicuous and clearly visible to the public if it isn't at every entrance.)
If you abide by the statute in posting your signs and a CHL comes onto your property armed with their handgun, it is a Class C Misdeameanor, and it becomes a Class A Misdemeanor when you ask them to leave and they don't.
Don't believe me about the signage, read for yourself from HB 910:
This is Penal Code § 30.06, as amended by
HB 910, [The first (A) you come across is the Paragraph (A) that is mentioned in (B)(i)]:
(3)"Written communication" means:
(A) a card or other document on which is written
language identical to the following: "Pursuant to Section 30.06,
Penal Code (trespass by license holder with a
concealed handgun), a person licensed under Subchapter H, Chapter
411, Government Code handgun licensing law), may not
enter this property with a concealed handgun"; or
(B) a sign posted on the property that:
(i) includes the language described by
Paragraph (A) in both English and Spanish;
(ii) appears in contrasting colors with
block letters at least one inch in height; and
(iii) is displayed in a conspicuous manner
clearly visible to the public.
This is Penal Code §30.07, as amended by
HB 910 [The first (A) you come across is the Paragraph (A) that is mentioned in (B)(i)] :
(3) "Written communication" means:
(A) a card or other document on which is written
language identical to the following: "Pursuant to Section 30.07,
Penal Code (trespass by license holder with an openly carried
handgun), a person licensed under Subchapter H, Chapter 411,
Government Code (handgun licensing law), may not enter this
property with a handgun that is carried openly"; or
(B) a sign posted on the property that:
(i) includes the language described by
Paragraph (A) in both English and Spanish;
(ii) appears in contrasting colors with
block letters at least one inch in height; and
(iii) is displayed in a conspicuous manner
clearly visible to the public at each entrance to the property.
And, remember, you can always skip the signs altogether and hand out cards with the statutory language on it.
