In Chula Vista's 91914 corridor, Blueline Builders and Construction Inc. holds CSLB license #1061018 as a Class B general building contractor established in 2019 for commercial construction, ADA-compliance upgrades, and tenant improvements. Metal-stud framing and drywall scope on commercial build-outs feeds directly into finish painting by trade subcontractors such as Montgomery Paint Contracting. The firm's portfolio spans site concrete, seismic retrofit work, and full construction management for multi-trade projects throughout eastern Chula Vista. ADU and garage-conversion projects in the region often begin with architectural plans from ADUs & Garage Conversions | Sprawl Design, feeding into Blueline's structural framing and concrete foundation scope. Structural applications include reinforced-concrete flatwork, rebar doweling into existing footings, and CMU block wall construction for commercial partition and retaining-wall installations.
