Our Mission

The Long Island Builders Institute (LIBI), formed in 1941, is an association of building industry professionals dedicated to making Long Island a better place to live and work by creating a balance between the economy, the environment, and the achievement of the American Dream of Ownership in our communities.

Our organization represents commercial and residential builders, remodelers, multi-family developers, rental buildings, general contractors, and professionals serving Long Island.

Business Opportunity

As the leading voice of the building industry on Long Island, LIBI members are committed to building homes and communities that are safe, strong, and sustainable. Our members build most of the 5,000 or more homes produced on Long Island annually; purchasing land, products, and services equivalent to about $1 billion each year.

LIBI serves as a business referral source for builders, remodelers, and associate members selling directly to the public. We respond to consumer inquiries, through database referrals given by telephone and online. LIBI also serves the public with referral information by appearing at major home shows and occasionally sponsoring our own.

Networking is LIBI’s most treasured business opportunity. Members learn from each other, exchange information, sell, buy, and make deals. Events occur at monthly general membership meetings, East End Chapter meetings, and many committee meetings and seminars.

A Special Thanks To All Of Our Sponsors

LIBI is proud to partner with some of the most highly respected building industry companies. Our sponsors play an integral role in our ability to provide resources and support to our members and the Long Island community at large. We are grateful for their continued commitment to helping us achieve our mission.
