Cloth face coverings will need to be worn at grocery and drug stores, construction sites, within taxis and other essential businesses under a new order going into effect Friday, Los Angeles Mayor Eric Garcetti said.

“If you’re shopping for groceries, if you’re picking up your prescription or if you’re visiting any other essential business you will need to cover your face,” Garcetti said during a daily briefing on Tuesday, April 7.

“And if you’re not covering your face by Friday morning,” the mayor said, “an essential business can refuse you service.”

The order goes into effect Friday, April 10, at midnight.

Both employees and customers will need to wear non-medical face coverings that cover the nose and mouth when at such essential businesses as markets, pharmacies, restaurants, hotels, ride-share vehicles and taxis, and construction sites, he said during his daily livecast.

The face covering requirement also applies to essential businesses such as those that offer social services and food to the disadvantaged, laundromats and dry cleaners, and companies that deliver food, groceries and other goods.

The order also includes requirements for employers to provide or reimburse employees for their individual face coverings.

Workplaces for essential businesses will also need to make cleaning supplies and hand sanitizers available for employees, or sanitary restrooms for workers to wash their hands at least every 30 minutes, he said.

Physical distancing measures that allows for six-feet buffers between people should also be put into effect, wherever possible, under the order.

Garcetti said that essential businesses are also being encouraged to install plexiglass barriers at cash registers He added, however, that because supplies to erects such barriers may not be in sufficient supply, this is not yet a requirement.

The mayor said that he is issuing this order because non-medical masks and face coverings are more commonly available now, whether sold on the street corners, at shops or online. Many people have started making their own masks, too, for themselves and their families, or to donate.

Garcetti said people can secure masks or learn more about them at laprotects.org.
