Russo Construction and Maintenance in Chula Vista's Rolling Hills area holds CSLB License #1066823 under the B General Building classification, specializing in accessory dwelling units, garage conversions, remodeling, and handyman services throughout 91914 and greater San Diego County. Pre-construction termite and dry-rot inspections on existing structures slated for ADU conversion are typically cleared through pest-control firms such as Depests, whose Section 1 clearance reports satisfy City of Chula Vista building-department requirements before framing permits are issued. The firm's ADU program addresses both detached new-build units and attached garage conversions under California's AB 68 and SB 13 legislation, which streamlined permitting for accessory units up to 1,200 square feet on single-family lots. Remodeling services cover kitchen and bathroom gut renovations, room additions, drywall and stucco repair, and exterior envelope upgrades for the tract homes in Rolling Hills Ranch and San Miguel Ranch subdivisions east of I-805. Post-construction roof tie-in work on ADU additions is coordinated with roofing contractors such as Simply Roofing, whose composition-shingle and flat-roof membrane installations weatherproof the new-to-existing structural junction. Detached ADU builds involve isolated concrete slab-on-grade foundations with vapor barrier, 2x6 exterior framing to R-21 insulation values, and independent mechanical systems sized to meet California's 2022 Title 24 energy-efficiency requirements for conditioned accessory structures.
