NYC J-51 Extension Heard by City Council; Vote Still Pending

NYC J-51 Extension Heard by City Council; Vote Still Pending

On September 9, 2026, the New York City Council’s Committee on Housing and Buildings held a hearing addressing the Mayor’s housing plan and a number of housing-related legislative proposals, including Introduction 1015-2026, the bill that would extend and expand the City’s J-51 property tax abatement program. The Committee, chaired by Council Member Pierina Sanchez, heard Int. 1015 along with several other housing measures as part of the broader hearing.

The hearing is a step toward restoring J-51 for construction completed after the expiration of the outgoing “J-51 Reform Program”. Earlier this year, New York State amended the Real Property Tax Law to authorize New York City to continue J-51 for another ten years, but City legislation is still necessary to implement the extension.

The Council’s own committee materials make clear that J-51 is being viewed not simply as a tax incentive, but as an important component of the City’s housing-preservation strategy. The Committee Report notes that the Mayor’s housing plan expressly supports “incentivizing building improvements through a renewed and expanded J-51 program,” and describes J-51 as a critical tool in the City’s existing preservation framework that helps owners finance major repairs, maintain the City’s aging housing stock, and undertake energy-efficiency improvements. The report also highlights the significant scale of the program—approximately $213 million in J-51 tax expenditures in FY 2026—and explains that State law has already been amended to permit a ten-year extension, leaving City Council legislation as the remaining step needed to implement it.

Proposed J-51 Program Would Apply Back to June 30, 2026

If enacted in its current form, Int. 1015 would cover eligible construction with a completion date on or after June 30, 2026 and before June 30, 2036. This is particularly important because the prior J-51 Reform program covered construction completed after June 29, 2022 and before June 30, 2026. In effect, the proposed legislation is designed to prevent a gap between the two programs.

Because Int. 1015 has not yet become law, projects completing now cannot yet receive benefits under the proposed program. But once enacted, the legislation would reach back to eligible projects completed beginning June 30, 2026. The bill also protects those early projects from losing their filing opportunity while the legislation remains pending: an application would be due by the later of four months after the new law takes effect or four months after the project’s completion date.

Larger J-51 Benefits

The proposed extension would also make J-51 substantially more valuable.

Under the current J-51 Reform law, the aggregate abatement generally may not exceed 70% of the certified reasonable cost (“CRC”) of eligible construction. Int. 1015 would increase that maximum to 100% of CRC, with the benefit continuing to be recovered through annual property tax abatements over a period of up to 20 years.

In addition, the J-51 application filing fee would become reimbursable as part of the tax abatement. For an approved application, the bill provides that an amount equal to the filing fee paid would be added to the aggregate amount otherwise eligible for abatement.

For cooperative and condominium buildings, the bill would also increase the average assessed valuation eligibility ceiling from $45,000 per dwelling unit to $60,000 per dwelling unit, with the $60,000 threshold adjusted annually for inflation.

For cooperative and condominium developments, the higher assessed-value threshold would significantly expand eligibility. Based on the Green Co-op Council’s analysis, the number of eligible co-op and condominium developments would increase from approximately 3,569 under the $45,000 threshold to 5,378 under the proposed $60,000 threshold—an increase of 1,809 developments, or about 51%. The totals reflect 3,009 eligible co-operatives and 2,369 eligible condominium developments under the proposed threshold.

What Happens Next?

Despite the September 9 hearing, Int. 1015 has not yet been calendared for a vote. The Council’s legislative record currently lists the bill as “Laid Over in Committee.” The September 9 history reflects both the committee hearing and the decision to lay the bill over; there has not yet been a committee vote or final Council vote. (NYC Council)

We expect the City Council ultimately to approve a J-51 extension, particularly given the State authorization, the Administration’s expressed support for a renewed program, and the significant Council sponsorship of Int. 1015. But enactment is not yet complete without a vote.

In the meantime, owners with capital projects that completed on or after June 30, 2026—or that are currently underway—should begin evaluating potential J-51 eligibility and maintaining detailed records of construction costs, permits, commencement and completion dates, and the scope of work. If Int. 1015 is enacted in its present form, those projects could qualify retroactively for the enhanced J-51 benefits.

We will continue to monitor Int. 1015 as it moves through the City Council and will provide updates when the bill is calendared for a committee or Council vote.
