New York Balcony Solar Law (SUNNY Act): What Passed, What's Still Missing

New York's SUNNY Act passed the legislature in June 2026 and is pending Gov. Hochul's signature. It legalizes 1,200W plug-in solar — but doesn't require landlords or HOAs to allow it.

New York's SUNNY Act (Solar Up Now New York) passed both chambers of the state legislature on June 1, 2026. It's pending Governor Kathy Hochul's signature. The bill would allow plug-in solar up to 1,200 watts without a utility interconnection agreement — the same basic framework as Utah and Maine.

What makes New York interesting: ConEd issued a memo supporting the bill. That is not something utilities typically do. It's also what makes the fine print worth reading carefully.

What the SUNNY Act Does

Wattage limit: 1,200W — in line with Utah and Maine, lower than Colorado's 1,920W.

No interconnection agreement required: Under the bill, plug-in solar owners would not need to enter into a utility interconnection agreement before installing. This is the central reform — the standard process for any grid-tied solar system in New York currently requires an application, review, and formal approval, which can take weeks and cost money.

Notification instead of approval: Owners would notify their utility within 30 days of installation. No pre-approval, no fees, no application.

Safety standard: Devices must comply with fire codes and be approved by an accredited testing laboratory. The bill does not name UL 3700 specifically (it was introduced before that standard existed), but UL 3700 or UL 1741 SA certification would satisfy the requirement.

NY-Sun relevance: NY-Sun is NYSERDA's primary solar incentive program. It covers rooftop installations and community solar subscriptions. The SUNNY Act does not bring plug-in solar into NY-Sun eligibility — these are separate frameworks. Plug-in solar under the SUNNY Act is exempted from interconnection rules precisely because it is classified outside the standard net-metering and solar program categories.

Why ConEd's Support Is Significant

ConEd issued a memo to lawmakers describing the SUNNY Act as striking an "appropriate balance" and noting that small plug-in systems "pose minimal engineering or grid impact risk." The utility said the measure "aligns with enabling greater customer access to small-scale clean energy solutions while continuing to uphold essential standards for safety and grid reliability."

ConEd rarely supports bills that reduce its regulatory authority over connected devices. The fact that it does here signals the utility's view that 1,200W plug-in systems are genuinely low-impact enough to not require the standard interconnection review process.

National Grid, which serves Upstate New York and Long Island outside ConEd territory, has not issued a comparable statement. Their position post-signing is worth watching.

The Part Everyone Is Missing: No Landlord or HOA Mandate

Here is the honest caveat buried in most coverage of the SUNNY Act: the bill does not require landlords or HOAs to permit plug-in solar panels.

From the bill text and reporting: the SUNNY Act exempts qualifying systems from utility interconnection requirements. It does not create a new right for tenants to install solar over a landlord's objection. It does not void HOA restrictions on balcony modifications.

This is a meaningful distinction for New York City specifically. Most NYC renters live in buildings with lease clauses that govern what can be placed on balconies, attached to railings, or plugged into outlets beyond standard household appliances. Even if the SUNNY Act passes, a landlord can still say no. An HOA can still deny installation.

New York does have existing property law that protects solar installations — but the protections are weaker than California's and were not written with plug-in systems in mind.

NYC Co-op Buildings: A Separate Issue

Co-op buildings are the most complicated case. In a co-op, you own shares in a corporation rather than the apartment itself. The co-op board governs use of all spaces, including balconies. Board approval is typically required for any modification to common or limited-common areas.

The SUNNY Act does not override co-op board authority. If your co-op board prohibits solar panels on balconies, the SUNNY Act will not help you. Your path is board approval — which means presenting:

  • The system specs and UL certification
  • A statement on anti-islanding safety (the system shuts down during grid outages, protecting utility workers and building wiring)
  • Confirmation that the installation is temporary, non-penetrating, and removable

Some co-op boards have become more receptive to these arguments, particularly in buildings with Local Law 97 compliance pressure. A plug-in solar system on individual unit balconies is a cost the building doesn't bear, while it contributes marginally to reduced grid demand.

NYC Building Code: Current Position

The NYC Department of Buildings has not issued specific guidance on plug-in solar systems. Under current code, any electrical modification to a dwelling requires permits and licensed electrician work. Plugging a device into an existing outlet — which is what plug-in solar does — does not typically require a permit, because you are not altering electrical infrastructure.

The ambiguity is whether a plug-in solar system is "electrical work" (requiring permit) or an "appliance" (requiring no permit). The SUNNY Act resolves this at the state level by classifying qualifying devices as appliances. Until it is signed into law, the NYC DOB interpretation could cut either way.

What Changes When Hochul Signs

If Governor Hochul signs the SUNNY Act:

  • ConEd, National Grid, and PSEG Long Island cannot require interconnection agreements for qualifying systems
  • Owners notify utility within 30 days — no pre-approval needed
  • The "appliance" classification is established in state law, providing a clear basis to avoid permit requirements
  • Landlord and HOA restrictions are not affected — those still apply

What doesn't change: Your landlord can still prohibit it. Your co-op board can still require approval. If you're a NYC renter, the SUNNY Act alone does not give you the right to install solar on your balcony — it only removes the utility barrier.

The Honest Read on New York

New York has more renters than any state except California — approximately 3.2 million renter households in NYC alone. The SUNNY Act addresses one of the four barriers to plug-in solar (utility interconnection) while leaving the other three in place: landlord consent, HOA/co-op board approval, and product certification.

That's not a reason to dismiss it. Removing the utility barrier is real. ConEd's support means the notification process will likely be lightweight in practice. For homeowners with outdoor space and no HOA, the SUNNY Act is a genuine unlock.

For NYC renters in apartments — which is most people asking about this — the more important step is the conversation with your landlord or co-op board, not the utility notification.
