🏗️ 🔌 What Developers, Owners, and Buyers Need to Know Now

If you are planning new construction in New York, the rules around how buildings are powered are changing. Those changes can directly affect your design, your timeline, and whether your project can be approved for occupancy.

Beginning in 2026, many new buildings in New York will no longer be allowed to install gas, oil, or propane systems. This includes systems used for heating, hot water, and other common building needs.

Instead, these buildings will be required to rely on electric systems. Ideally, those systems will be powered by cleaner energy sources.

This is not a future goal or a policy concept. It is a building permit requirement that is already reshaping how projects are planned across the state.

WHAT THE ALL-ELECTRIC BUILDINGS ACT DOES, IN PLAIN ENGLISH

New York’s All-Electric Buildings Act is designed to reduce emissions from new construction. It does this by limiting the use of fossil fuels in buildings that have not yet been built.

In simple terms, the law says many new buildings may no longer install systems that rely on fossil fuels. That includes natural gas, heating oil, propane, and similar fuels.

This restriction applies to common equipment used for space heating and water heating.

Instead, projects are expected to use electric alternatives such as heat pumps and electric water heaters. These systems are already common in many parts of the country. However, they require different design assumptions.

Electrical capacity, panel sizing, and early utility coordination become much more important.

THE DATES THAT MATTER MOST

One of the most important things to understand is this. The law is triggered by when a building permit is filed, not when construction begins.

For permits filed on or after December 31, 2025, which effectively means January 1, 2026, new buildings seven stories or fewer must generally be all electric.

For permits filed on or after December 31, 2028, which effectively means January 1, 2029, the requirement expands to cover most other new buildings statewide.

There is also an important transition rule for projects already in progress. State guidance ties applicability to whether a permit application is “substantially complete” by the end of 2025.

In everyday language, that means the application must be far enough along to be formally accepted by the local building department before the cutoff date.

Projects that meet this threshold may proceed under earlier rules. Projects that do not may need to redesign.

WHAT IS PROHIBITED UNDER THE LAW

In buildings covered by the Act, fossil-fuel-powered systems are generally prohibited. This includes equipment that relies on natural gas, oil, propane, or similar fuels.

During plan review, local officials will examine mechanical schedules, equipment lists, and specification sheets. Their goal is to confirm that prohibited systems are not included.

Compliance does not end with drawings. Final approval is tied to what is actually installed in the building.

EXEMPTIONS, AND HOW TO THINK ABOUT THEM REALISTICALLY

The law does include exemptions, but they are limited and specific.

Certain hospitals and medical facilities may qualify. Some manufacturing and industrial uses may also qualify. Commercial food establishments, emergency infrastructure, and backup power systems are included under defined circumstances.

Existing buildings, renovations, and additions are generally not covered by the Act itself. However, other rules may still apply.

In New York City, emissions from large existing buildings are regulated separately.

One commonly discussed exemption involves electric grid capacity. The Act allows an exemption where electric service cannot be reasonably provided by the grid.

Proposed guidance suggests a very narrow interpretation. It may apply only when switching to electric service would delay a project by roughly eighteen months or more.

The key point is this. Exemptions must be documented and confirmed early. They should never be assumed late in the process.

HOW ENFORCEMENT ACTUALLY WORKS

Compliance is enforced through New York’s statewide building code. It is administered by local building departments, often referred to as the authority having jurisdiction.

There are two moments when compliance matters most.

The first is during plan review. This is when the city or town reviews drawings and specifications before issuing a permit.

The second is during inspections and final signoff. Approvals depend on whether installed systems match the approved plans.

A certificate of occupancy allows a building to be legally used. It can be delayed or denied if all-electric requirements are not met.

Penalties for unresolved violations can include daily fines and court-ordered fixes.

HOW THIS FITS INTO THE BIGGER POLICY PICTURE

The All-Electric Buildings Act operates alongside other climate and building policies.

In New York City, Local Law 97 limits carbon emissions from many large existing buildings. While that law does not require electrification, it has pushed many owners toward electric systems.

At the national level, energy policy has moved in a different direction. Recent federal actions have favored continued fossil fuel use.

Environmental groups such as the Natural Resources Defense Council have challenged those actions in court. The U.S. Environmental Protection Agency has become a central player in those disputes.

For project planning in New York, the most important reality is local. Building permits are issued locally and enforced locally.

Federal debates do not pause local enforcement.

PRACTICAL STEPS YOU CAN TAKE RIGHT NOW

If you are developing, buying, or advising on new construction in New York, plan for electrification early.

Start by confirming when your permit will be filed. Determine whether it can realistically be accepted as complete before the end of 2025.

Coordinate early with utility providers. Understand service requirements, potential upgrades, and realistic timelines.

If you believe an exemption applies, document it clearly on the plans. Confirm it with the local building department before committing to a design.

Electrification is not only a compliance issue. It is also a scheduling and financing issue.

Delays tied to redesigns or utility upgrades can affect carrying costs, loan terms, and delivery timelines.

FREQUENTLY ASKED QUESTIONS

Does this mean New York is banning gas in existing homes and apartments

No. The Act focuses on new construction and generally does not apply to existing buildings.

What does all electric mean for a typical building

It usually means electric heating and cooling systems, often heat pumps, electric hot water, and larger electrical service.

Is this law moving forward despite lawsuits

Yes. Courts have allowed the law to proceed while litigation continues.

What is the biggest mistake teams make

Assuming this is a future trend instead of a current permitting requirement.

CLOSING THOUGHT

New York’s direction is clear. Starting in 2026, many new low-rise buildings must be built without fossil-fuel systems. By 2029, the requirement expands much more broadly.

Projects that move smoothly treat electrification as a starting point. They coordinate early with utilities and confirm compliance before permits are filed.

If you are planning new construction in New York, now is the time to align design with the permit calendar.
