Sonny Builders in Chula Vista holds CSLB license #1059558 as a B-classification general building contractor, covering kitchen remodels, bathroom renovations, roofing, room additions, and accessory dwelling units from its Melrose Avenue office in the 91911 corridor. Electrical rough-in and panel upgrades required for ADU sub-panels and kitchen appliance circuits follow the same National Electrical Code load-calculation standards applied by Cano Electric on residential service upgrades. The company's in-house design team produces 3D renderings, construction blueprints, and permit-ready plan sets, consolidating architecture and construction under one contract. Exterior hardscape and retaining-wall phases coordinate with Southwest Boulder & Stone for natural flagstone, decomposed granite, and boulder selections that integrate with the structural footprint. Full gut-renovation packages include structural header removal, LVL beam installation, seismic holdown hardware per Simpson Strong-Tie HDU specifications, and Title 24 energy-compliance documentation for the City of Chula Vista building department.
