The state renewed J-51 for 10 years in May 2026. The City Council still has to act before buildings can use it.
The J-51 tax abatement was renewed for 10 years. Governor Hochul signed the renewal on May 28, 2026, and it covers eligible work completed on or after June 30, 2026 and before June 30, 2036. The old program ended for work completed after June 29, 2026, and benefits under the new one still wait on a New York City local law.
I have been selling co-ops in Upper Manhattan for over 25 years. A building's abatement shows up in the monthly maintenance, so J-51 status belongs in any co-op purchase conversation.
J-51 is a New York City property tax exemption and abatement for building rehabilitation. It covers capital work such as boilers, windows, elevators, roofs, facade masonry, waterproofing, plumbing and electrical work, and the savings reach unit owners through lower maintenance in a co-op or a lower tax line in a condo. When a benefit ends, the full assessed value becomes taxable.
| Item | Under the J-51 Reform Program | Under the 2026 renewal |
|---|---|---|
| Eligible work | Completed after June 29, 2022 and on or before June 29, 2026 | Completed on or after June 30, 2026 and before June 30, 2036 |
| Average assessed value cap per apartment | $45,000 | $60,000, about $550,000 in market value, adjusted yearly with the consumer price index |
| Share of project cost recoverable | Up to 70% | Up to 100% of the Certified Reasonable Cost |
| Minimum project cost | $1,500 per apartment | $1,500 per apartment, unchanged |

The state law authorizes New York City to adopt a local law for the renewed program. The City Council has to act before buildings can receive benefits. Past rule-making has taken several months, so boards that finish work in the meantime are waiting on the Council.
The average assessed value is measured on the start date of construction, so work already underway can still qualify if the upgrade is eligible. The renewed program also requires the work to be completed within 30 months after commencement. Cosmetic improvements and luxury amenities are not covered.

A $200 or $300 monthly maintenance increase changes the debt-to-income calculation on a mortgage application. Ask the managing agent two questions before you sign a contract. First, does the building currently receive a J-51 abatement? Second, what is the certified abatement end date and the projected monthly maintenance change when it phases out?
If a building has capital work planned, also ask whether the board expects the renewed J-51 to apply and who is handling the application. That answer affects whether an assessment is likely.
For buyers interested in Washington Heights or Inwood co-ops, ask about J-51 status before settling on a price.
I can pull the tax abatement history on any building you are considering and walk you through what changes when it ends.
Schedule a Free ConsultationOwners in a J-51 building should ask the managing agent and board treasurer for the current abatement schedule. Boards with capital projects planned should confirm the building's average assessed value against the $60,000 cap, using the Department of Finance assessed value divided by the number of apartments, and talk to a tax attorney about project start dates and the 30-month completion window.
Boards planning Local Law 97 compliance upgrades should check whether the work is on HPD's eligible list. HPD publishes the eligible improvements and the reasonable cost schedule.
