Suffolk County’s New Building Code Updates for 2025: What Homeowners Must Know Before Starting Projects

Suffolk County Homeowners: Navigating the Game-Changing Building Code Updates Coming in 2025

As we move through 2025, Suffolk County homeowners planning construction or renovation projects face significant changes to New York State’s building codes that will directly impact their projects. The State Fire Prevention and Building Code Council voted to recommend major updates to the state’s building code, which is updated every five years and sets minimum standards for construction statewide. The draft updates include rules requiring most new buildings to be all electric starting in 2026, as mandated by a law passed two years ago.

The All-Electric Building Mandate: What You Need to Know

Starting on January 1 next year, most new buildings across the state are required to be all electric. This represents the most significant change to building codes in recent years. With the rules now entering the final stage of the approval process, New York remains on track to be the first state to enact such a ban.

For Suffolk County homeowners, this means that new construction projects will need to incorporate electric heating systems, electric water heaters, and electric cooking appliances instead of traditional gas-powered alternatives. Heat pumps—including ductless mini-splits—are an increasingly popular choice for efficient heating and cooling, even in cold climates. NYStretch’s insulation and air sealing requirements help optimize heat pump performance by reducing energy losses, allowing them to operate more efficiently.

Enhanced Energy Efficiency Requirements

The new draft code also tightens a slew of other standards in a bid to make buildings more energy efficient and save residents money over the long term. New York will soon implement a more stringent energy code based on the International Code Council’s 2024 International Energy Conservation Code and ASHRAE 90.1 2022, the energy standard set by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers. Anticipated changes include stricter air leakage and insulation requirements, mandatory U-factors for curtain walls, and insulation to prevent thermal bridges.

These enhanced requirements will affect various aspects of home construction, including improved insulation standards, stricter air sealing requirements, and upgraded building envelope performance. Homeowners should expect higher upfront costs but significant long-term energy savings.

Timing and Implementation

The final code changes, adoption, and effective dates are still to be determined but are anticipated to possibly be early fall of 2025. This timeline gives homeowners a narrow window to plan their projects accordingly. If you’re considering a major renovation or new construction, it’s crucial to understand how these changes will affect your project timeline and budget.
