Where to start: NYC Accelerator
Before any loan or rebate, there is a free front door. NYC Accelerator is sponsored by the NYC Mayor's Office of Climate & Environmental Justice, and building owners and property managers can get free expert help with building upgrades, local-law compliance, incentives and financing (NYC Accelerator, Incentives and Programs page). The program says its team has provided free assistance to more than 30,000 buildings since 2015 (NYC Accelerator, Incentives and Programs page), and the City's own PACE guidelines describe it as a free concierge service for technical and financial guidance on building decarbonization (NYC PACE Financing Program Guidelines v4.0, §1).
Two things make it more than a help desk. First, DOB and NYC Accelerator jointly maintain the City's list of financial incentives, tax credits and financing options for Local Law 97 compliance (DOB Local Law 97 page) — it is the reference the regulator itself points to. Second, an owner who later needs a §28-320.7 adjustment must have engaged NYC Accelerator and been assigned an Account Manager before applying (DOB §320.7 Adjustment User Guide (v2, 6/24/2025)). The free program is a prerequisite for the hardship route, not an alternative to it.
One open point: none of the Accelerator pages we reviewed state a building-size or ownership threshold for its services — they address building owners and property managers generally — so confirm scope with the program directly.
How NYC C-PACE financing works
NYC C-PACE is the City's property-assessed clean energy program. It was created in April 2019 by Local Law 96 of 2019 as the Sustainable Energy Loan Program, codified at Title 11, Chapter 30 of the Administrative Code, with the Department of Finance's rules at 19 RCNY Chapter 58 (Admin Code Title 11 Ch. 30 (LL96/2019); 19 RCNY Ch. 58). The state enabling law is General Municipal Law Article 5-L, and the City's stated purposes include helping owners comply with its building greenhouse-gas emissions limits (DOF Notice of Adoption, 19 RCNY Ch. 58). Local Law 42 of 2021 opened it to new construction as well as retrofits and renovations of existing buildings (DOF Notice of Adoption, 19 RCNY Ch. 58; LL42/2021).
The program is administered by the New York City Energy Efficiency Corporation (NYCEEC) on behalf of the City, in coordination with MOCEJ (NYC PACE Financing Program Guidelines v4.0, §1). NYCEEC oversees applications and approves the pre-qualified lenders who make the loans (NYC Accelerator, NYC PACE Financing page), and is itself a qualified lender (NYCEEC, NYC C-PACE page). The current Program Guidelines are version 4.0, revised June 26, 2026 (NYC PACE Program Guidelines v4.0, cover).
What owners get is long-term, fixed-rate financing covering up to 100% of project costs with no cash up front (NYC Accelerator, NYC PACE Financing page). What differs from a bank loan is repayment: a PACE Charge due semi-annually on January 1 and July 1, paid to DOF in the same manner as property taxes and remitted to the lender (NYC PACE Program Guidelines v4.0, §8). The loan stays on the tax bill and transfers with the building on sale (NYC Accelerator PACE Financing one-pager (2026)). A missed payment automatically becomes a PACE Charge Lien, accruing interest at the same statutory rate as an unpaid property-tax lien and appearing on DOF late-payment notices (NYC PACE Program Guidelines v4.0, §8).
Who qualifies for C-PACE and what it can pay for
Eligibility runs on the site, the borrower and the project:
| Location | One of the five boroughs; a residential property must have three or more units (NYC PACE Program Guidelines v4.0, §3). |
|---|---|
| Property types | Commercial, industrial and office buildings; properties owned by tax-exempt organizations, including religious institutions; 3+ unit residential buildings; certain condominiums (NYC PACE Program Guidelines v4.0, §3). NYCEEC's summary: every building type except 1–2 family homes (NYCEEC, NYC C-PACE page). |
| Borrower | Must own the real property and owe no civil penalties, taxes or other debt to the City; a leasehold owner needs the fee owner's agreement (19 RCNY §58-03(b); DOF Notice of Adoption). |
| Term | No longer than the weighted average useful life of the measures financed — the guidelines' example is 20-year heat pumps plus a one-year construction period, allowing a 21-year term (NYC PACE Program Guidelines v4.0, §3). |
| Savings test | Retrofits generally need a savings-to-investment ratio of 1.0 or greater; pre-qualified measures such as electrification are exempt, and avoided Local Law 97 penalties count as savings (NYC PACE Program Guidelines v4.0, §3 (SIR) and §5 (Embodied Carbon note)). |
| Audit | Energy efficiency improvements must be recommended by an energy audit, and renewable systems by a feasibility study, completed within two years; an audit prepared under the City's 2009 energy audit law is acceptable (NYC PACE Program Guidelines v4.0, §3). |
| Completed work | Retroactive financing is allowed if construction finished within three years before the financing agreement is signed, with the term reduced for useful life already elapsed (NYC PACE Program Guidelines v4.0, §3). |
The savings test is where Local Law 97 enters the math. Because penalties the project avoids count as savings, a building with a large exposure can clear the 1.0 ratio on measures that would not pay back on energy alone — the free LL97 calculator gives a first estimate of that exposure. The audit requirement also rewards buildings that keep their Local Law 87 audit current. Beyond equipment, the program can finance necessary hard and soft costs such as asbestos or lead mitigation or roof upgrades (NYC Accelerator PACE Financing one-pager (2026)). What the guidelines do not set is a fixed maximum term in years: the only cap is useful life.
J-51 R tax abatement: who qualifies and what it pays
The original J-51 program is closed to new work: the statutory deadline for completing eligible work was June 29, 2022, and HPD does not accept applications for work finished after that (HPD, Tax Incentives J-51 page). Its replacement, J-51 R, was enacted by Local Law 122 of 2024 at NYC Admin Code §11-243.2 under state authority added by Chapter 536 of the Laws of 2023 (RPTL §489(21)), with HPD's rules at 28 RCNY Chapter 62 (NYC Admin Code §11-243.2 (LL122/2024); 28 RCNY Ch. 62). Application materials became available in February 2025 (HPD press release, Feb. 12, 2025). HPD determines eligibility and issues the Certificate of Eligibility; DOF administers the benefit (DOF, J-51 Exemption and Abatement page).
| Benefit | Abatement of existing property taxes of up to 8 1/3% of the certified reasonable cost of the work each year for up to 20 years, capped at 70% of that cost in total (HPD, J-51 Reform page; NYC Admin Code §11-243.2). For co-op, condo, Mitchell-Lama and redevelopment-company buildings the annual abatement cannot exceed 50% of the taxes payable in that twelve-month period (HPD Notice of Adoption, 28 RCNY Ch. 62). |
|---|---|
| Eligible buildings | Rentals where at least 50% of units are affordable to households at or below 80% of Area Median Income, or that receive substantial governmental assistance under a regulatory agreement; Mitchell-Lama (PHFL Article II) and redevelopment-company (Article V) developments (HPD Notice of Adoption, 28 RCNY Ch. 62); and co-ops and condos whose average assessed value per unit does not exceed $45,000 (HPD press release, Feb. 12, 2025; 28 RCNY Ch. 62). |
| Eligible work | Construction completed after June 29, 2022 and before June 30, 2026 (HPD Notice of Adoption, 28 RCNY Ch. 62), meeting a minimum scope of $1,500 per dwelling unit and appearing on HPD's certified reasonable cost schedule (HPD, J-51 Reform page; 28 RCNY Ch. 62). HPD lists modernized heating systems, heat pumps, energy-efficient hot water heaters and electrical-capacity upgrades for electrification among the LL97-relevant items (HPD press release, Feb. 12, 2025). |
| Application | Due April 30, 2025 for work completed on or before December 30, 2024; otherwise within four months of the completion date (HPD, J-51 Reform page; 28 RCNY Ch. 62). Filing fee $1,000 plus $75 for each dwelling unit above six (HPD, J-51 Reform page). |
Read the dates together and the current window is closing: HPD is still accepting applications for work completed on or before June 29, 2026, and the four-month application clock on those projects runs out in late October 2026. HPD states that the State Legislature has authorized an extension of J-51 R and that, if the City Council enacts the full authorized extension, work completed after June 29, 2026 and before June 30, 2036 would become eligible; until the Council acts, work completed after June 29, 2026 is not eligible and cannot be applied for (HPD, J-51 Reform page). Check HPD for the Council's action before relying on either outcome. Boards should read this alongside the LL97 co-op and condo guide, since the $45,000 per-unit assessed-value test decides which co-ops and condos can use it at all.
Con Edison and NYSERDA incentives
Utility and state incentives reduce the project cost before any financing is sized. The programs below are the ones we verified against an official page; each publishes its own current application rules.
| Con Edison AMEEP | The Affordable Multifamily Energy Efficiency Program serves existing affordable multifamily buildings with five or more residential units in New York City and Westchester County (Con Edison, Affordable Multifamily Program page). Con Edison advertises up to $2,200 per unit in energy incentives for enhancing the efficiency of a 5+ unit affordable multifamily building (Con Edison, Affordable Multifamily Program page). |
|---|---|
| Con Edison C&I | The Commercial & Industrial program offers prescriptive (fixed-rate) and custom (per kWh or therm saved) incentives. For electric measures, eligibility is a Con Edison commercial electric account averaging over 100 kW peak demand on a rolling 12-month basis, excluding multifamily buildings; for gas measures, a Con Edison commercial gas account other than SC-14 or negotiated-contract service. Incentives are awarded first come, first served and subject to available program funding (Con Edison, Savings for Commercial & Industrial page). For 2026, Con Edison says to submit the project application package between May 1 and September 30, 2026, and to complete installation and submit paperwork by October 15, 2026 (Con Edison, Savings for Commercial & Industrial page); check the page for the current cycle. |
| NYSERDA FlexTech | Cost-shares 50–75% of an energy study to identify energy-cost and low-carbon upgrade opportunities in multifamily buildings facing Local Law 97 (NYSERDA, Planning Ahead for Local Law 97 page). Open to commercial, industrial, institutional and multifamily facilities, including small businesses and nonprofits, that pay into the electric System Benefits Charge (NYSERDA, FlexTech Program page). |
| NYS Clean Heat | Incentives for installing energy-efficient heat pumps for space heating and cooling and/or domestic hot water in multifamily buildings (NYSERDA, Planning Ahead for Local Law 97 page). |
Two limits on this list. Con Edison's market-rate multifamily incentive amounts sit in a separate program document we did not verify, so they are not stated here. And other federal, state and utility programs may apply to a given building; this page covers only those we could check against an official source, so absence here is not a statement that a program does not exist.
The LL97 financial-constraint adjustment
Local Law 97 itself contains a relief valve for buildings that cannot finance the work. Section 28-320.7 lets DOB grant case-by-case adjustments to a building's emissions limit on two grounds: external constraints such as landmark status or physical site conditions, effective for up to three calendar years, and financial constraints, effective for up to one calendar year (NYC Admin Code §28-320.7, §28-320.7.1 (LL97/2019)) (1 RCNY §103-12(c)(5)). The financial ground applies where the cost of financing the required capital improvements would prevent the owner from earning a reasonable financial return, or where the building meets the law's definition of financial hardship — and the owner must also show it was ineligible for city-funded or local-law financing programs and pursued all available incentives (NYC Admin Code §28-320.7(2) (LL97/2019)). (We read the statute from the enacted 2019 local law, not the consolidated code; the current rule, 1 RCNY §103-12, describes the same framework.)
“Financial hardship” is narrow: for the combined two years before applying, the building had property-tax or water/wastewater arrears, or outstanding HPD emergency repair program balances, that put it on DOF's annual tax lien sale list, or, for a tax-exempt nonprofit (RPTL §420-a, 420-b, 446 or 462), negative revenue less expenses certified by a CPA or by affidavit under penalty of perjury (NYC Admin Code §28-320.1 (LL97/2019)). DOB's rule then sets financial-constraint tests by building type:
| Most buildings | Debt service coverage ratio below 1.15, calculated under DOB guidance (1 RCNY §103-12(c)(3)(iii)). |
|---|---|
| Regulated affordable or debt-free | Income-to-expense ratio below 1.05 for buildings under an affordable-housing regulatory agreement or with no debt (1 RCNY §103-12(c)(3)(iii)). |
| Co-ops and condos | Three-year average carrying-charge increase 5% above inflation (1 RCNY §103-12(c)(3)(iii)). |
| Tax-exempt nonprofits | Negative revenue after expenses over the combined two years before the application (RPTL §420-a, 420-b, 446 or 462 exempt buildings) (1 RCNY §103-12(c)(3)(iii)). |
| Tax lien sale list | Inclusion on DOF's tax lien sale list (1 RCNY §103-12(c)(4)). |
If granted, the financial-constraint adjustment sets the limit equal to the building's actual emissions, valid for up to one year; an external-constraint adjustment is valid for up to three years with the limit described by the RDP (DOB §320.7 Adjustment User Guide (v2, 6/24/2025)). DOB's guide lists the external constraints accepted so far: certain industrial and manufacturing properties, hospitals, certain landmarked buildings (with an LPC denial and all other measures implemented), state-regulated crematories, data centers, and mandatory Times Square signage (DOB §320.7 Adjustment User Guide (v2, 6/24/2025)).
How to apply, and what else reduces the penalty
The application ties back to everything above. It needs an affidavit from NYC Accelerator confirming the owner worked with it and pursued all city, state, federal, private and utility incentives and every program funded by the city or enabled by local law that provides financing for energy reduction or sustainability measures, in which it could reasonably participate (1 RCNY §103-12(c)(3)(i); DOB §320.7 Adjustment User Guide (v2, 6/24/2025)) — a description that fits NYC C-PACE, which Local Law 96 of 2019 enabled, although the rule names no program — plus evidence that the owner bought the maximum greenhouse-gas offsets or renewable energy credits authorized under 1 RCNY §103-14(e) (1 RCNY §103-12(c)(3)(ii); §103-12(b)(6)) — see the RECs and offsets guide. DOB's sequence: engage NYC Accelerator and be assigned an Account Manager, purchase the maximum offsets, obtain an RDP or CPA attestation, and submit in BEAM by that year's reporting deadline (DOB §320.7 Adjustment User Guide (v2, 6/24/2025)). The application is filed with the annual emissions report by a registered design professional (1 RCNY §103-12(c) (introductory paragraph); NYC Admin Code §28-320.7.2). Fees: $690 for a financial-constraint application under §103-12(c)(3), $300 for a tax-lien-sale-list application under §103-12(c)(4), and $3,540 for external constraints (DOB §320.7 Adjustment User Guide; 1 RCNY §101-03).
The penalty at stake is the tons of CO2e over the building's limit multiplied by $268 (1 RCNY §103-14(h); NYC Admin Code §28-320.6), plus gross floor area × $0.50 for each month a report is missing within the 12 months following May 1 (1 RCNY §103-14(g)(1); NYC Admin Code §28-320.6.2); the calculator estimates the first. Short of an adjustment, three things reduce it: a demonstration of good faith efforts may result in a mitigated penalty for the year claimed (1 RCNY §103-14(i)(2)); a mediated resolution is an agreement with DOB not to bring an enforcement proceeding, on terms the Department determines (1 RCNY §103-14(j)(3)); and the tribunal must weigh mitigating factors including good-faith efforts, compliance with a §28-320.7 adjustment, unforeseeable events and the owner's access to financial resources (NYC Admin Code §28-320.6.1 (LL97/2019)).
Two earlier routes are closed: the original 2021 application deadlines for §28-320.8 (special circumstances) and §28-320.9 (nonprofit hospital and healthcare) were extended by Local Law 77 of 2023 to January 1, 2025 (DOB Service Notice 7/21/2023); DOB states both windows are now closed (DOB Local Law 97 page). So the order of operations for 2026 is the one this page follows: Accelerator first, incentives next, C-PACE or J-51 R for the balance, and the §28-320.7 adjustment only once the affidavit can honestly say the rest was tried.
