The J-51 Exemption and Abatement Program is a key tax incentive for New York City affordable housing. J-51 offsets property taxes for residential buildings that undergo major capital improvements – including critical energy efficiency upgrades – through two channels: lowering the taxable value of the property, and directly reducing the tax owed. This program specifically pertains to affordable housing developments, co-ops, condos, and rental buildings.
On Wednesday, September 9, the City Council’s Housing Committee will hold a hearing to consider Intro 1015 of 2026, a bill that would extend the J-51 tax abatement program – currently set to expire in June of this year – to 2036. The bill would also increase eligible residences to those with an average addressed valuation of up to $60,000 per dwelling unit.
As with all property tax exemptions and abatements, J-51 is governed by state law, and thus any bill extending the program’s lifespan must be passed by both the State Legislature and the City Council. New York State did its part this Spring, when the extension and expansion of J-51 passed as part of the State Budget.
Now, the City Council must do their part. The J-51 program is essential if the city is to meet its decarbonization targets under Local Law 97 (LL97). Properties that fall under the requirements of LL97 often struggle to finance large-scale retrofits, like heat pump installation, envelope upgrades, or high-performance windows. J-51 is one of the few tools available to offset these capital costs while keeping housing costs stable for New Yorkers.
In order to keep housing affordable, sustainable, and in compliance with LL97, these building owners need assistance. By passing Intro 1015, the City will ensure that New Yorkers can afford their homes and benefit from the energy upgrades they deserve.
