M Kevin O'Neill Construction in Chula Vista holds three active CSLB licenses — #377869 (B General Building), #448855 (A General Engineering), and #351512 — spanning concrete, masonry, pile driving, pressure foundation jacking, cabinet and millwork, and lathing and plastering classifications. That multi-license scope means foundation pours and underground utility rough-ins run on the same site as plumbing contractors such as Primo Plumbing, whose sewer and water laterals must pass inspection before any slab is placed. The firm's BuildZoom score places it in the top seven percent of all California licensed contractors, a ranking derived from permit history, bond status, and workers'-compensation compliance data. From its Del Mar Avenue base in western Chula Vista, the company handles structural concrete, CMU block walls, retaining-wall engineering, and pressure-foundation jacking for settled or shifting residential slabs common in the area's expansive-clay soils. ADU additions and garage conversions — a growing segment in Chula Vista driven by California's AB 68 and SB 13 accessory-dwelling-unit legislation — frequently start at the drafting table with ADUs & Garage Conversions | Sprawl Design before O'Neill's crew breaks ground on the structural phase. The company's C-19 pile-driving classification enables deep-foundation work including driven steel H-piles and helical piers torqued to engineered load capacities exceeding 50,000 pounds for hillside and fill-soil residential sites.
