As of Friday, all 200,000 businesses in the Big Apple are required to put out their bags of trash in garbage bins, as communities across the county and world have long done.

The requirement is the next phase in the city’s efforts to curb what Mayor Eric Adams’ administration has called a “24-hour rat buffet” of trash on sidewalks.

The city in August started requiring restaurants, convenience stores and bars to use a sturdy trash can with a secure lid and extended the requirement to chain stores the following month.

Now every city enterprise, including mom-and-pop shops, must comply. Then in the fall, residential buildings with nine or fewer units will fall under the mandate.

Commercial trash makes up nearly half of the some 44 million pounds of refuse collected by the city each day, according to Adams, who has made combating the city’s rodents a focus.

City officials will issue warnings for the first month of the new mandate but will begin issuing summonses in April, Sanitation Commissioner Jessica Tisch said in media appearances Friday morning with Adams.

Joshua Goodman, a spokesperson for the city sanitation department, said the city’s only requirement for businesses is that they use a solid bin with a secure lid.

Businesses must work with their waste hauler to find out what kind of bin they should use, because business trash is collected by private haulers, not the city.
