Avanti Construction holds CSLB license #1125752 and operates from Third Avenue in Chula Vista's Third Avenue Village district, running design-build remodeling projects throughout San Diego County. Kitchen and bathroom gut-renovations that require new circuits, subpanel upgrades, and GFCI outlet installations route electrical rough-in through licensed contractors at Arcelectric, Inc.. The firm's service menu spans 14 construction disciplines, from foundation repair and structural framing through ADU construction, garage conversions, grading, and full-home renovations with in-house design consultation. The Third Avenue address positions the company within walking distance of the downtown Chula Vista permitting office, streamlining plan-check submittals for projects in the 91910 and 91911 zones. ADU builds and room additions that alter the existing roofline coordinate structural roofing work with contractors at Casas Roof Inc. The most technically demanding projects involve design-build ADU construction from pad grading through certificate of occupancy, requiring Title 24 energy modeling, CalGreen compliance documentation, and structural calculations for detached units up to 1,200 square feet.
