Mamdani supported
Proposal 1, a 2024 amendment to the
Constitution of New York that made it unconstitutional to engage in discrimination based on ethnicity, national origin, age, disability, sex (including
sexual orientation,
gender identity, and
gender expression), pregnancy and pregnancy-related outcomes, or reproductive healthcare and autonomy. Mamdani's mayoral campaign platform included opposition to
wealth inequality and
racism. He supports the
New York Health Act, which would establish
single-payer healthcare in New York State.
Childcare and education Mamdani supports a universal
pre-kindergarten childcare system. He has proposed giving all new New York City families "
baby baskets" containing products such as diapers and nursing supplies. Mamdani introduced a bill to eliminate
New York University's and
Columbia University's state
property tax exemption and direct those funds to the
City University of New York system, which has historically struggled with funding. In a June 2025 interview with
Der Blatt, a newspaper associated with the
Hasidic movement of Judaism, Mamdani expressed a desire to defend Hasidic
yeshivas (institutions for
Torah study) from accusations of failing to meet state educational standards. He said "I will listen to your leaders" on education and "I will work to protect you from anyone who wants to disturb your way of life".
Crime and policing Mamdani has argued that increasing policing and incarceration does little to prevent harm and that "dignified work, economic stability, and well-resourced neighborhoods" can more effectively keep the public safe. He has advocated a more community-based approach to reducing crime, focusing on homeless outreach and anti-violence programs. He contends that there is too much reliance on police to fix societal problems, saying, "Police have a critical role to play, but right now we are relying on them to deal with the failures of the
social safety net of reliance that is preventing them from doing their actual jobs." He has proposed a Department of Community Safety to expand
mental health outreach. In a June 2020 tweet, Mamdani voiced support for defunding the NYPD. During the 2025 mayoral race, he said he would work with the police rather than defund them, emphasizing their importance in dealing with violent crime and the role of social workers and mental health professionals in addressing underlying causes and prevention. In October 2025, Mamdani apologized for describing the NYPD as racist. In September 2025, Mamdani condemned the
assassination of Charlie Kirk, saying that
political violence has no place in the United States.
Environment Mamdani views climate action as essential to achieving social justice in New York City. In 2021, he organized volunteers and lobbied Governor
Kathy Hochul to prevent the expansion of a gas-fired peaker power plant in Astoria, citing environmental concerns for low-income non-white communities. Mamdani has also backed statewide measures such as the All-Electric Buildings Act, which prohibits installing fossil-fuel equipment (e.g., gas stoves) in new buildings, and supported introducing congestion pricing in Manhattan to reduce traffic-related emissions. Mamdani was an advocate of the "Build Public Renewables Act", which has been described as a state-level
Green New Deal. As a mayoral candidate, Mamdani proposed a comprehensive decarbonization and resilience agenda. His "Green Schools for a Healthier New York City" blueprint would retrofit 500 public school buildings with rooftop solar arrays and upgraded HVAC systems; build 500 green schoolyards; transform heat-absorbing asphalt into green space serving students and community residents; convert 50 schools into year-round resilience hubs to offer shelter and resources during extreme heat, storms, or flooding; and extend tax incentives such as J-51 benefits to support building owners' compliance with Local Law 97.
Health care Mamdani supports the
New York Health Act, which would establish
single-payer healthcare in New York State.
Immigration Mamdani supports enforcement of New York's
sanctuary laws, which bar
Immigration and Customs Enforcement (ICE) from entering schools, hospitals, and city property without a judicial warrant, and has advocated for stronger sanctuary laws. Mamdani has decried the actions of ICE under the
Trump administration as being
fascist. He has also proposed creating a commission to ensure compliance by city agencies and contractors. He has pledged that if he is elected mayor, the city will provide legal representation for all immigrants in detention proceedings. On March 12, 2025, Mamdani confronted former
ICE acting director
Tom Homan in Albany about ICE's
recent arrest of student activist
Mahmoud Khalil; Mamdani yelled, "Do you believe in the
First Amendment?" Mamdani supports
abolishing ICE, stating that the agency is "terrorizing people no matter their immigration status, no matter the facts of the law, and no matter the facts of the case".
LGBTQ+ rights Mamdani staunchly supports
LGBTQ+ rights. He aims to establish NYC as an LGBTQ+ sanctuary city and establish the Office of LGBTQIA+ Affairs to "expand and centralize the services, programs, and support that LGBTQIA+ New Yorkers need across housing, employment, and more." Mamdani says
LGBTQ+ people who became homeless due to their identity would benefit from his
cost-of-living policies. As part of his platform, he supports expanding and protecting gender-affirming care citywide. He proposed an immediate investment of $65million in public providers to ensure funding for medical treatments that lose
Medicaid coverage and promised to ensure hospital accountability.
Transportation Mamdani supports permanently eliminating
New York City bus fares. He advocated for a
fare-free pilot program on
MTA buses, which was launched on the
Q4,
B60,
Bx18,
M116 and
S46/96 routes in September 2023. The program saw a 30% increase in ridership on weekdays, predominantly from people earning less than $28,000 a year. Across the five routes made free, assaults on bus operators dropped by 38.9%. The fare-free program ended in August 2024 after state lawmakers did not reauthorize it. In response, Mamdani said, "the MTA was opposed to this program... because they were saying that now is not the time to create any kind of confusion around fare collection." He estimates that it would cost New York City $650million per year to eliminate bus fares. In December 2022, Mamdani introduced a series of bills for the 2023 session called "Fix the MTA". He proposed free bus travel over the next four years across
the Bronx,
Brooklyn,
Queens, and then
Manhattan and
Staten Island. The Formula Three Act would fill the $2.5billion shortfall of the MTA with another plank freezing fares at $2.75. Another plank would have set aside further money for more frequency, such as six-minute headways for trains and the 100 most-used bus routes, then using any additional funds to increase service by 20%. In 2023, Mamdani co-introduced a bill to enact a weight-based vehicle-registration fee to dissuade people from owning heavier vehicles in an effort to make streets safer. Mamdani supports
congestion pricing in New York City and drafted a bill with New York state senator
Michael Gianaris titled "Get Congestion Pricing Right" to increase bus service frequency and increase the number of fare-free buses. == Economic policy ==
