Nearly 770,000 New York City apartments are co-ops or condos, which means a single shared roof often sits above dozens of separate owners. That turns a simple solar installation into a group decision about approvals, who gets the savings and which incentives the building can claim. In 2026 the incentive picture has also changed: the residential federal credit has ended and new federal-credit projects face a 2027 in-service deadline, while NYC and New York State incentives remain.

Occupied Co-op and Condo Apartments in NYC (2023). About 450,000 co-op and 318,000 condo apartments, roughly 22% of occupied housing. Source: NYC Comptroller analysis of the 2023 NYC Housing and Vacancy Survey.
Chart summary: New York City had roughly 450,000 occupied co-op apartments and 318,000 occupied condo apartments in 2023, together about 22% of the city’s occupied housing. Co-ops outnumber condos by roughly 1.4 to 1, which matters for solar because a co-op corporation owns the whole building and roof, while condo owners hold the roof collectively.
π§ Board Approval
Can a NYC Co-op or Condo Board Legally Install Rooftop Solar?
Short answer: Yes. Whether a project can go ahead is decided by your governing documents and your board (and sometimes a shareholder or owner vote), not by a single citywide solar rule.
In a co-op, the corporation owns the building and roof, so solar is typically approved like any other capital project under the proprietary lease and bylaws. In a condo, the roof is a common element, so approval and funding follow the declaration, bylaws and budget (a special assessment is a common route). Vote thresholds vary, so ask your building’s attorney to confirm the process and to review any roof-lease or power-purchase agreement.
Two practical steps come first:
Structural review. Have a licensed engineer confirm the roof can carry panels and racking before you accept final quotes.
Roof replacement timing. Under NYC Local Laws 92 and 94 of 2019, a new building, an enlargement, or an alteration that replaces the entire roof deck or assembly must provide a sustainable roofing zone, which means a solar system of at least 4 kW, a green roof, or a combination. Replacing only the roof covering is generally not subject to the requirement. If a full replacement is already planned, solar may be partly required anyway. See the NYC Department of Buildings notice.
Panel output also declines slowly. NREL’s long-running degradation research reports a median of roughly 0.5% per year, so a system would still produce about 88% of its original output after 25 years (0.995 raised to the 25th power). That is a useful figure for a board presentation, but your installer’s warranty terms are what actually apply.
π Key Insights
How Are Solar Savings Shared Among NYC Co-op and Condo Units?
Short answer: It depends on how the building is metered. Master-metered buildings pass savings through building-wide charges, while individually metered units need credits assigned to each resident’s account.

Under New York’s VDER framework, electricity your system exports to the grid earns Value Stack credits, while electricity consumed on-site reduces what you buy from the utility (see NYSERDA’s VDER FAQ). Because credit values and net-metering eligibility depend on system size and customer class, ask your installer to model both exported and self-consumed energy for your actual account. Whatever allocation you choose, record the formula in a written board resolution before interconnection so every shareholder or owner can see how credits are divided. Our solar net metering calculator can help you test scenarios. For a full cost breakdown by state and system size, see our guide to How Much Do Solar Panels Cost in 2026?.
ποΈ Incentives
What Incentives Apply to NYC Co-op and Condo Solar in 2026?
Short answer: The two most reliable layers are NYC’s 30% property tax abatement and New York State’s 25% credit. The federal credit is now time-limited, and NY-Sun availability must be checked before budgeting.
NYC Solar Property Tax Abatement. For systems whose service starts between January 1, 2024 and January 1, 2035, the abatement equals 7.5% of the installation cost per year for four years, or 30% in total. Each year it is limited to the lowest of that amount, the property’s annual tax, or $62,500, and it applies to tax class 1, 2 and 4 properties (co-ops and condos are generally class 2). Properties receiving ICAP, 421-a, 421-b or 421-g benefits, or paying PILOTs, are not eligible. The Department of Buildings determines eligibility and the Department of Finance administers the benefit; read the NYC Department of Finance program page and confirm the filing deadline (commonly March 15 for the abatement to start that tax year) with your installer.

NYC Solar Property Tax Abatement: Cumulative Share of Installation Cost. 7.5% per year reaches 30% after four years, or $60,000 on a hypothetical $200,000 eligible cost. Source: NYC Department of Finance, service start 2024 through 2034.
Chart summary: The abatement is delivered in four equal annual steps of 7.5% of eligible cost, reaching 30% after year four. For a hypothetical $200,000 eligible installation cost, that is $15,000 a year and $60,000 in total, which is under the $62,500 annual cap but only usable if the building’s property tax bill is at least that large each year.
New York State Solar Energy System Equipment Credit. New York offers a personal income tax credit of 25% of qualified solar costs, up to $5,000. Tenant-shareholders in a co-op and condo owners can claim their proportionate share of costs when the corporation or association buys the system, and the Department of Taxation and Finance’s form instructions limit a co-op or condo system to 50 kW. It applies to a primary residence and requires tax liability, so check the current Form IT-255 instructions.
Federal credit. The residential Section 25D credit ended for expenditures after 2025. The commercial Section 48E credit still exists, but solar facilities that begin construction after July 4, 2026 must be placed in service by December 31, 2027 to qualify (details in this Chapman and Cutler summary). Energy storage is not subject to that in-service deadline. Whether a co-op corporation or condo association can use the credit depends on its tax status and liability, so consult a CPA first.
Sales tax. The 4% state tax and the 3/8% MCTD tax are exempt on commercial and residential solar equipment, and local tax is exempt only where the jurisdiction has enacted the exemption. Check Publication 718-CS for local treatment.
NY-Sun (NYSERDA). The standard-income residential MW Block incentive in Con Edison territory has closed, and per-watt rates for other categories change as blocks fill. NYSERDA lists enhanced incentives for regulated affordable multifamily housing: $1.60 per watt for Con Edison projects that are not community distributed generation, and $2.00 per watt for CDG projects without the Community Credit (NYSERDA multifamily incentives). Check NYSERDA’s live MW Block dashboard before putting any NY-Sun number in your budget.
β Worth It?
Is Community Solar Worth It for NYC Co-ops, Condos and Renters?
Short answer: Community solar is worth considering when your roof cannot host panels or when residents rent. Savings are smaller than owning a system, but there is no installation, no capital cost and no board vote for individual subscribers.
With community solar you subscribe to a share of an off-site solar project and receive credits on your Con Edison bill. NYSERDA notes that subscribers typically receive a discount of 5β10% off annual electricity costs, and that New York has more than two gigawatts of community solar (NYSERDA). Some projects offer higher discounts to income-eligible subscribers.
The tradeoffs are real. Credits depend on your subscription, so savings end if you cancel or move out of the utility territory, and you do not build equity in an asset. Rooftop ownership can cut more of the building’s own power costs and unlocks the NYC and state incentives above, but it needs a suitable roof, board approval and capital or financing. Compare both on your real bills with our solar ROI calculator.
π° System Cost
How Much Does NYC Multifamily Rooftop Solar Cost in 2026?
Short answer: Costs vary widely by roof, system size and crane access, so a single citywide price is not reliable. Use itemized quotes and subtract each incentive you qualify for.
As one reference point, NYSERDA’s published example for a 25 kW community-solar system on an affordable-housing property uses a $110,000 total cost before NYSERDA incentives, roughly $4.40 per watt. Cost per watt generally falls as system size rises, but dense-city labor, permitting and rooftop logistics keep New York quotes high, so collect at least three itemized proposals.
To estimate your own payback:
Start with the gross quote and subtract the NYC abatement, any NYS credit that shareholders or owners can claim, any eligible federal credit, and any NYSERDA incentive.
Estimate annual savings from self-consumed energy plus exported-energy credits. NREL’s free PVWatts tool gives an independent check on annual kWh output for your roof orientation and shading.
Divide net cost by annual savings. Payback is longer if you finance the system. To see how your state compares, our guide to Solar Panel Payback Period by State has the full data.

Yes. The roof is owned by the co-op corporation or is a common element of the condo, so the board can approve a project under its governing documents. Vote thresholds depend on your proprietary lease, declaration and bylaws, so have your attorney confirm the process. Start with a structural engineer's review and NYC Department of Buildings permits. If you are replacing the entire roof, Local Laws 92 and 94 already require a 4 kW solar system or a green roof.
Partly. The residential Section 25D credit for individual owners ended after 2025. The commercial Section 48E credit still exists, but solar projects that began construction after July 4, 2026 must be placed in service by December 31, 2027. Whether a co-op or condo association can use the credit depends on how it is owned, taxed and structured, so confirm with a CPA before signing a contract.
NYC's property tax abatement returns 7.5% of eligible installation cost per year for four years (30% total), capped at the lesser of $62,500 a year or the building's property tax, and it requires Department of Buildings approval. New York State's credit is 25% of costs, up to $5,000 per owner, claimed proportionally by co-op shareholders and condo owners. State and MCTD sales taxes are exempt on solar equipment. NY-Sun block availability changes, so check NYSERDA's dashboard.
It depends on metering. In a master-metered building, solar offsets the building's electric bill and the benefit reaches residents through maintenance or common charges. Individually metered apartments need credits assigned to each account, typically through community distributed generation or remote crediting arranged with the utility. Exports earn Value Stack credits under New York's VDER tariff. Document the allocation method in a written board resolution before interconnection.
It depends on the roof and the goal. Community solar needs no roof, installation or capital, and NYSERDA says subscribers typically save 5β10% a year. Rooftop solar can reduce more of the building's own electric costs and qualifies for NYC and state incentives, but it needs board approval, capital or financing, and a roof that can host panels. Use community solar when the roof is unsuitable, or for renters who cannot install panels.
