A NYC Co-op Just Financed Its Entire Heat Pump Retrofit with No Money Down. Here's How.

The most common objection we hear from building owners about LL97 compliance is: "We know we need to upgrade, but we can't afford it."

That objection just got a lot harder to make. In April 2026, CounterpointeSRE closed the first-ever C-PACE loan for a New York City co-op: a $1 million financing package for 304 West 89th Street, a 36-unit building on the Upper West Side. The project will replace the building's steam heating with mini-split and domestic hot water heat pumps.

Zero cash out of pocket. No special assessment for shareholders. Repaid through the property tax bill over 20+ years.

What is C-PACE?

C-PACE (Commercial Property Assessed Clean Energy) is a financing mechanism that lets building owners fund energy efficiency and clean energy projects with no upfront capital. The loan is repaid as an assessment on the property tax bill, typically over 20 to 30 years at a fixed interest rate.

Key features that make it different from a conventional loan:

• No cash upfront. C-PACE covers up to 100% of project costs including soft costs (engineering, permits, legal).
• Long terms. Repayment periods of 20 to 30 years mean low annual payments, often less than the LL97 penalty the project eliminates.
• Attached to the property, not the borrower. If the building is sold, the C-PACE obligation transfers to the new owner. No personal guarantees.
• Fixed rate. No floating rate risk. Predictable payments for the life of the loan.

Why this matters for co-ops and condos

Co-op boards have historically struggled to fund major capital projects. The options were limited: special assessments (unpopular), underlying mortgage refinancing (slow), or reserve fund draws (depleting). C-PACE adds a fourth option that avoids all three problems.

The 304 West 89th Street deal is a proof of concept. The building's heat pump installation is projected to cut fossil fuel use by 66% and avoid an estimated $44,000 in annual carbon penalties starting in the 2040 compliance period. The annual C-PACE payment is structured to be less than the combined energy savings and avoided penalties.

In February 2026, Herald Towers (a 690-unit Midtown apartment complex) closed an $8.5 million C-PACE loan through North Bridge for a full HVAC electrification. Average C-PACE deal sizes have jumped from $800,000 in 2017 to $40 million in 2026. The market is moving fast.

Full electrification projects get fast-tracked

NYSERDA updated its C-PACE guidance to give full electrification retrofits a "pre-qualified" status. That means buildings converting entirely from fossil fuels to electric heating are exempt from the Savings-to-Investment Ratio (SIR) requirement that slows down other projects. Less paperwork, faster approval.

The program also expanded eligibility to new construction and ground-lease properties, both previously excluded.

Stack C-PACE with other programs

C-PACE covers the financing. But you can still layer other incentive programs on top to reduce the total project cost before financing:

• NYSERDA window heat pump demos: Up to $20,000 per apartment for qualifying multifamily buildings (applications open through October 2026)
• NYS Clean Heat: Per-unit rebates for heat pump installations through Con Edison and National Grid
• LL97 Beneficial Electrification Credit: Buildings that install heat pumps get a deduction from their emissions calculation
• 179D federal tax deduction: Up to $5.94/sqft for qualifying energy projects (construction must begin by June 30, 2026)
• J-51 property tax abatement: 70% of improvement costs back over 12 to 20 years (work must be completed by June 29, 2026)

When you stack these programs, the net cost of a retrofit can drop dramatically. In some cases, the incentives plus avoided penalties exceed the total project cost. The building comes out ahead.

The math for a typical co-op

Consider a 100-unit co-op in Manhattan spending $2 million on a heat pump conversion:

• C-PACE annual payment (25-year term, 7% rate): ~$170,000/year
• Annual energy savings from electrification: ~$60,000
• Avoided LL97 penalties (2030 period): ~$45,000/year
• NYSERDA/Clean Heat rebates (one-time): ~$200,000 to $400,000
• 179D deduction (if construction begins before June 30): ~$580,000

Net annual cost after energy savings and avoided penalties: roughly $65,000/year. That's about $54/month per unit. And after the C-PACE loan is paid off, the savings continue indefinitely.

How to get started

1. Check your building's penalty exposure and incentive eligibility. Look up your building on CompliantLens (free) to see your LL97 penalty estimate and which programs apply.
2. Contact the NYC Accelerator. The city's free advisory service helps buildings navigate C-PACE applications and connects you with approved lenders. Learn more at accelerator.nyc.
3. Get an energy audit. NYSERDA's FlexTech program covers up to 50% of audit costs. You'll need one to size the project and apply for C-PACE.
4. Move fast on 179D and J-51. Both expire June 30, 2026. If you're planning a retrofit, starting construction before that date captures hundreds of thousands in additional savings.
