Structural Modification

Yes. Removal or modification of any load-bearing wall requires a building permit and structural engineering approval from the relevant Long Island town building department. No load-bearing work may be covered by drywall until the framing inspection has passed. Center Island Contracting coordinates engineering review and permit submission before any structural work begins.

Load-bearing walls are typically identified by a structural engineer or experienced contractor. Walls running perpendicular to floor joists, walls positioned above beams or columns, and walls running directly above foundation walls are common candidates. Definitive identification requires structural review. Center Island Contracting evaluates structural conditions during the pre-construction phase as a standard step before design is finalized.

LVL (laminated veneer lumber) beams and steel I-beams are the most common solutions for spanning new openings. The appropriate beam type, depth, and bearing conditions are determined by a structural engineer based on the span length and the loads being transferred from above. This structural engineering review is required before permits can be issued on Long Island.
