SJB Construction Incorporated, a Santee design-build firm founded in 1983, holds CSLB License #944884 and specializes in second-story and room additions across San Diego County. Each addition project requires coordinated electrical rough-in, and the firm schedules that scope alongside subcontractors such as Keil Electric on Magnolia Avenue. The company's design-build process begins with an on-site walk-through to establish structural feasibility, permit requirements, and a unified floor plan before any demolition starts. Flooring, countertop, and finish selections factor into each project budget, drawing on East County supplier networks that include Rayo Wholesale Floorcovering Supply on Woodside Avenue. Completed second-story additions typically involve engineered Simpson Strong-Tie hold-down connections, LVL ridge beams, and full Title 24 energy-compliance packages filed with the City of Santee Building Division.
