Barron Design and Development in Chula Vista holds CSLB license B675966 (General Building) and has operated as a design-build general contractor from Sea Vale Street since 1993. The firm's core specialization in accessory dwelling unit construction, kitchen renovations, and bathroom overhauls runs through every phase from permit drawings to finish carpentry, coordinating tile subcontractors such as Seaside Tile Inc for surface installations. ADU projects follow California Government Code Section 65852.2 setback and height requirements, with Barron handling city permit coordination, structural engineering, and utility tie-ins as a single point of contact. Full kitchen gut-renovations include cabinet layout, countertop templating, and plumbing rough-in coordination, while the electrical panel upgrades and circuit additions that accompany most layout changes are handled by trade partners including Cano Electric. The firm's highest-complexity projects involve two-story addition framing with engineered LVL headers, Simpson Strong-Tie connectors, and seismic hold-down hardware meeting CBC Chapter 23 lateral-force standards.
