Relating to the authority of a municipality or county to regulate or prohibit the carrying of a firearm on the premises of certain libraries.

HB 1138 amends Texas law to clarify that municipalities and counties may regulate or prohibit firearms on library premises. It directly affects local governments (cities/counties) and library patrons, particularly those carrying firearms. The key provision allows local authorities to ban firearms in libraries but explicitly exempts licensed carry permit holders under Texas Penal Code §46.15 or Occupations Code §1702. This bill clarifies existing local authority without creating new restrictions, focusing on library-specific rules while preserving legal carry rights for permitted individuals.
