Headline numbers

Across his nearly five years in the Assembly, Mamdani served as primary sponsor on at least 21 bills in the 2025 session alone and co-sponsor on 242 more [1]. Per state records summarized by Gothamist, 15 of the bills he attached his name to passed both houses of the Legislature in 2025, including the Medical Aid in Dying Act, which Hochul had until the end of 2025 to sign or veto [1].

Across his full Assembly tenure (2021 to 2025), only three Mamdani-sponsored bills became law. This was the figure Andrew Cuomo repeatedly cited during the 2025 primary debates, telling viewers at the first televised mayoral debate: "He's been in government 27 minutes, he passed three bills. That's all he's done" [2]. The three signed bills, whose Senate versions were all sponsored by state Sen. Michael Gianaris, addressed:

A bill requiring the state Department of Motor Vehicles to provide information about voter registration deadlines on its website (signed by Gov. Andrew Cuomo).

A bill enabling certain city employees to use sick leave for cancer screenings.

A bill clarifying landlord obligations regarding lead-paint inspections in pre-1960 residential buildings.

The fare-free bus pilot (2023 to 2024)

Mamdani's most significant policy achievement in Albany came not as a standalone bill but as a budget provision. In 2022, he introduced the "Fix the MTA Act," a package of proposals that included phasing out bus fares across the city. The fare-free bus provisions were folded into the 2023 state budget rather than passed as a separate bill [3, 4].

The pilot ran from September 2023 through August 2024 and made one bus line in each of the five boroughs free to ride: the Bronx Bx18A/B, Brooklyn B60, Manhattan M116, Queens Q4, and Staten Island S46/96 [5]. The MTA originally said the fare-free initiative would last six months; fares were not collected for 342 days [5].

By rider metrics, the pilot was a success. Ridership rose 30 percent on weekdays and 38 percent on weekends, and 23 percent of riders said they made trips specifically because the service was free [6]. About 43,000 riders used the free routes [5].

The pilot was not renewed by the legislature in 2024, citing MTA budget concerns. Mamdani sponsored a bill to extend and expand the pilot, which did not get a floor vote [1]. Per Politico New York and New York Magazine, Mamdani cast a protest vote against the 2024 state budget partly over the failure to renew the pilot; Mamdani has disputed that framing [2].

In March 2026, both the state Senate and Assembly's FY2027 one-house budget proposals called for reviving the pilot under Mamdani's mayoralty [3].

Taxi medallion debt relief (2021)

In fall 2021, Mamdani joined a 15-day hunger strike with NYC taxi drivers protesting predatory medallion loans. The Bill de Blasio administration ultimately reached a deal capping drivers' debt loads and monthly payments, securing what Mamdani's campaign described as more than $450 million in debt relief [7].

The campaign is not a strict "legislative record" item, but it is consistently cited by Mamdani as one of his defining accomplishments and is regarded as one of the moments that built his political profile in Queens [7]. The deal was implemented through executive action rather than legislation.

Co-sponsored bills of note

Mamdani co-sponsored or supported a wide range of legislation that did not bear his name as primary sponsor. Notable examples include:

The MENA Act (Middle Eastern and North African demographic categorization act), passed in 2023, created a recognized demographic category in state data collection [4].

The Medical Aid in Dying Act, which passed both houses in 2025 with Mamdani's co-sponsorship, allows doctors to prescribe lethal medication to terminally ill patients at the patient's request. Hochul had until the end of 2025 to sign or veto it [1].

A610, "Not on our dime!: Ending New York funding of Israeli settler violence act," which would have prohibited New York-based not-for-profit corporations from supporting Israeli settlement activity. It did not advance to a floor vote [4].

The TREES Act, which would expand state authority over street tree planting and maintenance [1].

Committee assignments

By May 2025, Mamdani had served on nine Assembly committees: Aging, Cities, Election Law, Housing, Insurance, Local Governments, Mental Health, Transportation, and the Asian Pacific American Task Force [8]. He chaired no committees, consistent with his status as a junior member representing a single Queens district.

Voting profile

Mamdani's voting record in the Assembly was consistent with his platform: he typically voted with the Democratic majority on housing, labor, and tax policy, and joined progressive members in occasional protest votes against budget compromises he felt did not go far enough. The fare-free bus pilot was the most-cited example of his willingness to break with leadership over budget priorities [2].

He was a reliable yes vote on labor bills (including expanded paid family leave), abortion-rights legislation, gun-control measures, and tenant protections. He voted against bail-reform rollbacks pushed by Hochul in 2024 budget negotiations [4].

Framing the record

How to read Mamdani's Albany record was the central question of the 2025 primary debates. Cuomo's framing was that three signed bills in nearly five years was a thin résumé for someone seeking to run the country's largest city [2]. Mamdani's counter-framing was that legislative impact in Albany is measured in budget influence and coalition-building, not standalone bill count, and that his fare-free bus pilot, taxi medallion campaign, and co-sponsorship of major legislation reflected real influence [2, 7].

Doug Turetsky, the former chief of staff at New York City's Independent Budget Office, told TIME after Mamdani's general-election win that the affordability proposals on which his platform rests are "feasible" but "tough to enact, and tough to enact quickly" [9]. The question of whether the same instincts that made Mamdani a non-traditional Assembly member will translate into mayoral governing success is one of the open questions of his term.
