Did you know nearly 1 in 4 homes sold on Long Island this year have been subject to New York’s Mansion Tax? 🏠

When the tax was created in 1989, the $1 million threshold was intended to apply to luxury homes. More than 35 years later, that threshold has never been indexed to inflation — while Long Island home prices have risen dramatically.

That’s why LIBI, alongside a coalition of Long Island business organizations, is calling on state lawmakers to modernize the Mansion Tax to reflect today’s housing market better.

As LIBI CEO Mike Florio told Newsday, “We’re not saying get rid of the tax… but it’s dated at this point.”

Thank you, Newsday, for highlighting this important conversation.

Thoughtful development is key to addressing Long Island’s housing needs and creating communities that work for both current and future residents.

LIBI is proud to support Cornerstone Melville, an $85 million mixed-use development proposed by Terwilliger & Bartone Properties within the Melville Town Center Overlay District.

The project would bring 168 rental and for-sale homes and more than 20,000 square feet of office and retail space to Melville — expanding housing choices while supporting the continued growth of the area.

With major new investment coming to Melville, including NYU Langone Health’s planned academic medical center, the need for housing near new jobs and economic opportunities will only continue to grow.

Terwilliger & Bartone has a proven track record of creating high-quality residential communities across Long Island, and Cornerstone Melville represents another opportunity for thoughtful development that meets the needs of a growing region.

As Long Island continues to grow and attract investment, our housing supply must grow with it.

LIBI CEO Mike Florio is featured in this week’s Long Island Business News discussing what it will take to strengthen Long Island’s construction industry and address the region’s housing shortage.

As one of three industry leaders interviewed, Mike highlights a challenge that continues to hold Long Island back: certainty in the development approval process.

Every housing development supports years of work for contractors, subcontractors, suppliers, engineers, architects, and countless local businesses. But without a more predictable and timely approval process, many projects never have the opportunity to move forward.

As Mike shared with LIBN:
“Long Island doesn’t suffer from a lack of interest in building housing—it suffers from a lack of certainty. If we can reduce unnecessary regulatory delays while maintaining strong environmental and community protections, we’ll produce more housing, create more jobs and improve affordability for the next generation of Long Islanders.”

LIBI will continue advocating for policies that create a more efficient, predictable approval process—because building more housing means creating more jobs, strengthening our economy, and improving affordability across Long Island.

The East End building community faces unique challenges — and addressing them starts with paying attention to what is happening at the local level.

Through the LIBI East End Chapter, our members are staying engaged with municipalities across the region, identifying the issues impacting builders and working together to advocate for practical solutions.

Get involved. Stay informed. Be engaged at every level. The stronger our participation, the stronger our collective voice for the East End building community.

To offer real solutions for local building backlogs, the trade community must be a direct partner with government officials.

In our newest East End Chapter meeting, we discussed how the ultimate goal of LIBI is to secure that crucial seat in the room, ensuring we’re the first call when it comes to construction, code changes, or regional development policies.

Make sure your voice is represented where it matters most. Learn more about LIBI’s active government advocacy efforts by visiting libi.org.

The opening of Heritage Westminster is another example of how thoughtful redevelopment can help address Long Island’s housing shortage while strengthening our communities.

By transforming a long-vacant commercial property into 428 new homes, this project delivers much-needed housing opportunities, revitalizes an underutilized site, and creates new energy for the surrounding business district.

As LIBI CEO Michael Florio shared with Newsday:
“It’s a perfect example of the things we could do here on Long Island revitalizing properties that no longer serve their purpose.”

With housing affordability remaining one of Long Island’s greatest challenges, projects like Heritage Westminster demonstrate the value of reimagining obsolete properties to meet today’s housing needs while supporting local economic growth.

Congratulation to Heatherwood and everyone else involved.
