Firearms and Ammunition - As introduced, removes the criminal offense of possession of a weapon in a building or on property that is properly posted; removes the requirement that the department of safety suspend or revoke a handgun carry permit for a violation of that offense by a handgun permit holder. - Amends TCA Title 39, Chapter 17, Part 13.

HB 985 modifies Tennessee's firearm laws by removing the criminal offense for possessing a weapon in a properly posted building or property, and eliminating automatic permit suspensions for this violation. It requires property owners who restrict firearms to post clear signage, install metal detectors at all public entrances, and have trained security officers inspect all visitors and bags. This primarily affects businesses, venues, and property managers seeking to prohibit firearms, while exempting libraries, law enforcement buildings, Head Start facilities, and certain licensed properties. The bill takes effect July 1, 2025, and shifts enforcement focus to physical security measures rather than criminal penalties for non-compliance.
