What CLJ does
CLJ Building Enterprises, Inc. is a Staten Island, New York-based general contracting firm founded in 1984 by Anthony Carollo. The company delivers commercial construction, residential construction, renovation and remodeling, custom home design, consulting, and project management services. It holds a New York City Department of Buildings General Contractor's License with Full Demolition and Concrete endorsements and a New Jersey General Contractor's License, giving it operating rights across both states for ground-up builds as well as structural and demolition work. The firm is privately held, bootstrapped with no external funding rounds, and operates with a headcount of 56 employees.
The company's project portfolio spans healthcare, hospitality, education, and commercial real estate, with completed work including the Staten Island University Hospital Birthing Suite, the Staten Island Mental Health facility (delivered to a Platinum green rating), Hampton Inn, Applebee's, Corporate Commons 3, Richmond Preparatory Charter School, Heart and Lung at 501 Seaview, and Eden 2. Project scale extends up to 330,000 square feet, indicating capability for mid- to large-institutional ground-up construction rather than only small-scale renovation. Customer segments are institutional and commercial owners, including hospital systems, hospitality brands, charter school operators, and commercial developers.
Revenue is generated through fixed-price construction contracts acquired via a sales-led go-to-market approach grounded in competitive bidding, owner-direct negotiation, and repeat referrals from architects and prior clients. The business model is project-cycle based with no recurring subscription or managed-services revenue layer; revenue therefore depends on the cadence of contract awards and project completion milestones rather than a long-tail customer base. The 40+ year operating history functions as a primary intangible asset during prequalification for institutional work.
