ICON Building Services on Chula Vista's Third Avenue holds CSLB #848727 with B-General Building and C-10 Electrical classifications, plus Arizona ROC #361199 for cross-border commercial projects. Tenant-improvement buildouts in retail and warehouse spaces require tight sequencing between electrical rough-in and HVAC installation, a coordination model that parallels Air Pro Heating & Air's commercial ductwork scheduling in the same South Bay market. Founded in 2004, the women-owned, Hispanic-owned firm specializes in LED lighting retrofits for big-box retailers and distribution centers, leveraging utility-company rebate programs to offset conversion costs for clients replacing legacy fluorescent and HID fixtures. Government contracts and nationwide rollout work extend the company's scope beyond San Diego County to multi-site interior and exterior lighting installations across commercial facilities. Pre-construction planning on adaptive-reuse projects in the Third Avenue Village corridor pairs ICON's electrical and general-contracting scope with the ADU-focused architectural drafting of Sprawl Design, streamlining permit submittals when structural, electrical, and finish schedules overlap. Highest-tier scopes involve full electrical service upgrades from 200-amp to 400-amp panels coupled with three-phase power distribution for industrial tenant improvements exceeding 20,000 square feet.
