General Contractor in Nassau County, NY

JZ Development & Management LLC is proud to serve homeowners and businesses throughout Nassau County, NY. From Hempstead to Great Neck, Garden City to Long Beach, our team delivers quality general contracting services across all of Nassau County's diverse communities.

As a Long Island-based general contractor with over 25 years of experience, we understand the unique building requirements and architectural styles found throughout Nassau County. The post-war housing stock in communities like Levittown and East Meadow often requires foundation reinforcement, updated kitchens, and stoop rebuilds to meet modern standards. Meanwhile, established neighborhoods in Garden City, Manhasset, and Great Neck call for premium finishes and meticulous attention to historic character. Nassau County's sandy coastal soil along the South Shore — from Long Beach to Freeport — demands specialized foundation work and moisture management that our team handles routinely.

Our full range of services — including masonry, concrete, epoxy flooring, renovations, and new construction — is available throughout Nassau County. We work with local building departments across Hempstead, North Hempstead, and Oyster Bay townships. Licensed (HI-67427), insured, and committed to delivering results that exceed your expectations.
