New Yorkers who swear by their stainless tumblers may soon get backup from City Hall. A new proposal in the City Council would require cafes, bubble tea counters and other drink spots across the five boroughs to serve beverages in customers' reusable cups and to post signs saying patrons can bring their own.
Supporters frame it as a simple way to cut down on single-use waste. Many shop workers see a tangle of sanitation rules, equipment limits and longer lines. That brewing fight now heads to a Council committee where the details will be hammered out.
What The Bill Would Require
Intro. No. 781, introduced March 26, 2026, by Councilmember Shaun Abreu, would bar food-service establishments from refusing a customer's reusable cup and would require any business that serves drinks in single-use plastic cups to post a sign stating: “Customers may request the service of beverages in their own reusable cups,” according to The New York City Council.
The proposal designates the Department of Health and Mental Hygiene and the Department of Consumer and Worker Protection as the agencies that would write the detailed rules and handle enforcement.
Supporters Call It Common Sense
Backers argue the measure is a basic step toward trimming the mountain of disposable cups that end up in trash cans and on sidewalks every day.
"The bill gives New Yorkers the choice to use reusable cups and is common sense," one supporter told the New York Post, which first reported the proposal and early reactions from shops around the city.
Shops Say It Is More Complicated
On the other side of the counter, some workers and owners say the idea sounds cleaner on paper than it is in a rush-hour line.
Employees at cafes and bubble tea shops told the New York Post they are worried about dirty or oddly shaped cups and about customers showing up with oversized containers in hopes of getting extra ounces. Staff at several boba counters said their automatic sealers are designed for a narrow range of cup diameters and that baristas measure recipe volumes, so they would not simply “top off” larger personal cups.
Sealing Machines Do Not Like Weird Cups
Commercial cup-sealing machines used in many boba shops typically accept top diameters of about 90–95 mm and depend on specific molds or adapters, according to manufacturers. That means saying yes to any random mug could mean new parts, slower manual sealing, or both.
Product listings and spec sheets show that some models can be refitted with custom molds, but that option adds cost and complexity for high-volume businesses. For a sense of the technical limits, see manufacturers such as Phoenixes and VEVOR.
Sanitation, Size Limits And Penalties
The proposal does not go as far as some shop owners fear. The bill text allows a food-service establishment to refuse a reusable cup "if the reusable cup is incapable of being washed and sanitized in accordance with standards set by the department of health and mental hygiene" or if its size "does not comport with beverage sizes used by the food service establishment," language taken directly from the measure.
The bill also assigns enforcement to the Department of Health and Mental Hygiene and the Department of Consumer and Worker Protection and sets escalating civil penalties of $100 for a first violation, $200 for a second, and $400 for a third and subsequent violation, according to the legislation posted by The New York City Council.
What Comes Next
The bill is now in the Council's Committee on Consumer and Worker Protection and cannot reach a full Council vote until the committee signs off. The listing for the bill on Intro.nyc shows it was introduced in late March and referred to committee, where supporters and opponents will get a formal chance to make their case.
Abreu's Track Record On Reusables
Councilmember Shaun Abreu has pushed reuse measures before, including a previous effort to allow reusable bottles at city sports venues, and supporters say that history is part of why advocates see this cafe-focused proposal as a natural next step. Local reporting on that earlier push provides context for the current fight, including coverage at West Side Rag.
Legal Takeaway For Businesses
If Intro. 781 becomes law, businesses that serve drinks in single-use plastic cups would need to post the required notice, spell out size and sanitation rules for acceptable cups, and train staff on when and how to refuse a container without inviting fines.
The committee process is likely to be where all the real-world concerns from sealing-machine vendors, small-shop owners and environmental advocates get translated into technical exemptions and clarifications.
For now, New Yorkers who already lug stainless tumblers or mason jars will be watching those hearings closely. The proposal puts an environmental goal up against the grind of day-to-day service at the counter, and whatever version emerges from committee will show which side got the cleaner fix.
