New York City's new mayor has big plans ahead.
Zohran Mamdani was inaugurated in a private ceremony at midnight on New Year's Eve at the Old City Hall subway station, which is only accessible by guided tour.
A public swearing-in ceremony at City Hall is open to 4,000 ticketed guests and will feature Rep. Alexandria Ocasio-Cortez and Sen. Bernie Sanders.
In an election in November 2025, Mamdani defeated former Gov. Andrew Cuomo and Republican nominee Curtis Sliwa to become the mayor of NYC with over a million votes.
Here is a look at Mamdani's key plans for NYC as its 111th mayor, along with their estimated costs.
Universal childcare
Expanding free childcare to babies and to toddlers under the age of three is Mamdani's most ambitious and costly plan.
NYC already offers free pre-school to many toddlers above three, but for parents with even younger kids, accessing childcare is a struggle. According to the New York Comptroller's Office, annual average childcare prices for one child in New York in 2023 were about $12,000 for home-based care, $17,476 for toddler center-based care, and $20,459 for infant center-based care. A 2024 report by public policy think tank 5BORO Institute found that more than 80% of families cannot afford day care for their children.
The Mamdani campaign estimates that providing childcare to all NYC families could cost $6 billion annually. The plan would be funded by the proposed tax raise on corporations and the wealthiest residents, and the campaign said it would also generate revenue through expanding the labor force. According to a January report from the NYC Comptroller, expanding free childcare would bring 14,000 mothers to the workforce and generate $900 million in labor income.
Fast and free buses
NYC has one of the highest densities of public transit users in the country, yet the city's buses average only eight miles per hour, and Mamdani wants to change that.
Mamdani proposed that buses be completely free to the more than a million riders every day, who are mostly commuters for work purposes.
He also plans to create more busways that are limited to other through traffic to speed up the transit.
The city currently offers a 50% discount on public transit fares to low-income residents, but fare evasion has remained at approximately 40% every quarter since 2024. Mamdani's campaign estimates that free buses would cost under $800 million every year.
This estimate does not account for Mamdani's plan to construct additional bus-only lanes.
More rent-stabilized homes — at better rates
Last summer, a city lottery opened for the first time in 15 years, allowing NYC residents to apply for help paying their rent, and more than 630,000 people joined the waitlist. The application only remained open for one week, but the need for affordable housing was on full display.
Mamdani plans to address the housing issue by tripling the city's production of publicly subsidized, rent-stabilized homes, at 200,000 new units over the next 10 years. The plan would benefit households that make less than $70,000 a year, and it would cost the city $100 billion over the next decade.
Separate from the plan to build, Mamdani plans to freeze rent for the one million rent-stabilized units across the city, which could be achieved with relative ease and comes at zero direct cost to the city's budget. This rent freeze would only affect rent-stabilized units, which make up a little under half of the city's rental stock, and would not apply to market-rate units.
Mamdani, as mayor, could appoint members to the Rent Guidelines Board who align with his affordability goals.
The plan could draw the ire of building owners, who would need to shoulder additional costs for maintenance and property taxes.
City-operated grocery stores
Mamdani has also suggested a pilot program of five city-run supermarkets, one in each borough, to bring down the cost of groceries. The program would require approval from the city council, and these grocery stores would be selling food at wholesale prices.
According to the NY State Comptroller's Office, the cost of food at home grew 65.8% between 2013 and 2023 in NYC, which far outpaces the rate of broader inflation.
Including the cost of rent, utilities, warehouse, property taxes, and the initial cost to stock up goods, the Mamdani campaign estimates that the five stores would cost $60 million annually.
Chicago's mayor, Brandon Johnson, is also pushing forward a similar idea. According to a feasibility study done in 2024, building three stores would cost the city $26.7 million upfront.
