Guns would be banned in schools and on playgrounds in New Orleans, and anyone convicted of domestic abuse would be barred from carrying concealed firearms, under a proposed ordinance backed by two City Council members and Mayor Mitch Landrieu.

The ordinance, introduced at Thursday’s council meeting, would also require that gun owners report the loss or theft of a firearm to the police.

The measure includes several new restrictions on firearm sales and possession in the city, including bans on owning or selling guns without serial numbers and new requirements for carrying concealed weapons.

Those provisions would likely raise challenges from gun-rights groups, which have been pushing court cases aimed at a variety of firearms restrictions since Louisiana voters approved a 2012 amendment to the state Constitution that limited gun control measures.

Council President Jason Williams, Councilman James Gray, Landrieu and Police Superintendent Michael Harrison are expected to discuss the proposed ordinance at a news conference Friday.

For the most part, the measure calls for penalties of fines of up to $500 and up to six months in jail, the maximum penalties the city is allowed to impose for municipal violations.

One provision would bar guns within 1,000 feet of schools, on school buses or at any city facility where youth-oriented programs are offered. People who have concealed-weapons permits would still be allowed to carry them within those zones, as would students enrolled in ROTC programs.

The ordinance also would prohibit anyone convicted of domestic abuse battery from possessing or carrying a concealed weapon for 10 years after the person’s sentence is completed.

Gun owners would also be required to file a report with police within 48 hours if a firearm is lost or stolen.

The sale of a gun without a serial number, unless that weapon is an antique or was originally manufactured without one, would be prohibited.

Those provisions seem to be aimed at cutting down on the supply of guns on the streets. Stolen guns are often resold and later used in crimes, and guns without serial numbers make it hard for police to track down their owners.

A final provision would create the crime of “negligent carrying of a concealed firearm.” That would ban carrying, possessing or brandishing a concealed weapon when it creates fear that the gun will be fired or a crime will be committed.
