Barajas Construction in Carlsbad's Aviara area has provided general contracting and commercial remodeling services since 2001, handling tenant improvements, restaurant build-outs, and full-scope renovations across San Diego County. Project management covers demolition, framing, drywall, finish carpentry, and coordination of licensed subcontractors for electrical and plumbing rough-ins — a multi-trade oversight model that keeps the same job-site schedules as the HVAC ductwork installed by Coastal Refrigeration Heating and Air Conditioning on concurrent Carlsbad commercial builds. Commercial scopes on Towhee Lane and the surrounding La Costa corridor include ADA-compliant restroom upgrades, storefront demising-wall construction, and fire-rated ceiling assembly per CBC Chapter 7. The firm coordinates city permit acquisition and inspector walk-throughs on behalf of property owners, reducing schedule gaps between rough and final inspections — a permitting workflow also familiar to ARK Architects on Carlsbad commercial entitlement projects. Structural retrofit scopes include moment-frame reinforcement, shear-wall installation using Simpson Strong-Tie holdowns, and epoxy-anchored steel connections per CBC Section 1613 seismic provisions.
