East Hampton’s 2024 Building Code Updates: New Propane System Requirements for Luxury Home Construction

East Hampton’s 2024 Building Code Updates Signal the End of an Era for Propane Systems in Luxury Home Construction

The luxury home construction landscape in East Hampton is undergoing a dramatic transformation as New York State prepares to implement one of the nation’s most ambitious building code changes. Starting January 1, 2026, most new homes and low-rise buildings (≤7 stories) built anywhere in New York State must be all-electric. That means no natural gas or propane equipment (and no new gas piping to serve it) in new construction permitted after that date.

Understanding the All-Electric Buildings Act

On July 25, 2025, the New York State Fire Prevention and Building Code Council approved the implementation of the All-Electric Buildings Act, which changes the state’s Energy Conservation Construction Code to prohibit fossil fuel systems in certain new buildings. Accordingly, starting January 1, 2026, New York State will require that most newly constructed buildings be fully powered by electricity.

For East Hampton’s luxury home market, this represents a seismic shift. Building equipment and systems using fossil fuels such as natural gas, heating oil and propane will be prohibited in many new buildings. This includes everything from heating systems and water heaters to cooking appliances and fireplaces that have traditionally defined luxury home amenities.

What This Means for Current Construction Projects

The timing of permit applications is crucial for developers and homeowners planning luxury construction projects. The rule keys off the date your building permit application is submitted and deemed “substantially complete.” If you’re in design now, timing matters. If a building permit is secured before 12/31/2025 – homes can build with natural gas or propane appliances.

However, existing homes: You can keep using and repairing your existing gas/propane systems; renovations and additions to existing buildings are not pulled into the ban. This distinction is particularly important for East Hampton’s many historic properties and luxury estates undergoing renovations.

East Hampton’s Enhanced Building Code Requirements

East Hampton has already implemented stringent building code updates that go beyond state requirements. As of October 3, 2016 Any Building Permit Application received needs to meet the NYS 2015 International Building & Energy Codes, any New Homes will require the HERS Certificate for the Energy Ratings. The NYStretch Energy Code-2020 supplement to the Energy Conservation Construction Code of New York State-2020, (hereafter referred to as “NYStretch”) published by the New York State Energy Research and Development Authority (hereafter referred to as “NYSERDA”), shall be effective for all building permit applications (applicable to new construction, substantial reconstruction, alterations, and additions) submitted on or after January 1, 2023, in the Town of East Hampton unless superseded by more restrictive provisions adopted herein by New York State, except that Section R403.6.2 of the NYStretch Code shall be severed from this local law and not be applicable.

Which will include “Blower Duct Tests on all New Construction.” “THIS WILL REQUIRE A BLOWER TEST & DUCT TEST FOR ALL NEW CONSTRUCTION.” These requirements ensure that luxury homes meet the highest energy efficiency standards even as they transition to all-electric systems.

The Role of Professional Propane Services During the Transition

While new construction will be moving away from propane systems, existing luxury homes in East Hampton will continue to rely on professional propane services for maintenance, repairs, and system optimization. This is where established local providers become invaluable partners for homeowners navigating this transition period.

What Luxury Home Builders Need to Know

The transition to all-electric systems requires careful planning and expertise. Heating & Cooling: Specify cold-climate heat pumps (ducted or mini-split); consider variable-refrigerant flow for larger homes. Hot Water: Use heat pump water heaters (hybrid or split systems). Cooking: Choose induction or high-performance electric ranges. Dryers & Fireplaces: Go electric dryer and electric fireplace (or design for architectural focal features without open flames).

Importantly, Natural-gas/propane standby generators remain permitted for emergency use; battery storage is also worth exploring. This exception allows luxury homes to maintain backup power systems, which are particularly important in East Hampton’s coastal environment.

Planning for the Future

If you’re planning new construction in 2026 (or beyond), assume all-electric from day one. If you’re renovating or adding on to an existing home, you can keep your current gas/propane systems—but it’s a great time to compare total cost of ownership for modern electric alternatives.

The building code changes represent New York State’s commitment to reducing greenhouse gas emissions as part of the Climate Leadership and Community Protection Act. The act was passed as part of the state budget in 2023, and it seeks to implement NYS’ energy mandates required by the Climate Leadership and Community Protection Act of 2019 (CLCPA). The CLCPA seeks to sharply reduce greenhouse gas emissions in phases by 2030 and 2050.

For East Hampton’s luxury home market, this transition period presents both challenges and opportunities. While new construction must adapt to all-electric systems, existing homes with propane systems will continue to benefit from professional service and maintenance. Working with experienced local providers ensures that homeowners can maintain their current systems safely and efficiently while planning for future energy transitions.

As East Hampton continues to balance its commitment to environmental stewardship with the luxury amenities that define its real estate market, professional propane services remain an essential resource for the community’s existing homes and estates.
