Charleston’s late-night bars could soon be made to pick up a lot more of the responsibility and cost in policing rowdy crowds.

An ordinance making its way through City Council requires bar operators to have set levels of security, police sidewalks in front of their business and make sure their parking lots are cleared-out 30 minutes after closing time.

Also, doors and windows where music is played would have to shut and sealed by 11 p.m., “management techniques” for crowds would have to observed and security personnel would have to wear readily identifiable clothing.

The “Late Night Entertainment Establishment Ordinance” was formally introduced to City Council this week.
