Quality Builder . Pro in Chula Vista's Eastlake area is a BBB-accredited construction company operating from Autumn Hills Drive in the 91913 zip code, handling residential and commercial projects across San Diego, Riverside, and San Bernardino counties. ADU and garage-conversion builds pair the company's framing crews with architectural planning consultants at ADUs & Garage Conversions | Sprawl Design for permit-ready drawings that comply with Chula Vista's current accessory-dwelling-unit ordinance and state AB 68 setback standards. The scope covers new home construction, kitchen and bathroom remodels, room additions, breakfast-nook conversions, outdoor living areas, solar panel sales and installation, tenant improvements, and commercial buildout projects. Finish phases that require porcelain, travertine, or large-format tile installation are coordinated with Seaside Tile Inc, whose modified thin-set and Schluter waterproof-membrane systems meet TCNA Handbook specifications for wet-area assemblies in Eastlake's newer housing stock. The firm's most technically intensive deliverable is a ground-up detached ADU on a zero-lot-line parcel, requiring fire-rated one-hour exterior wall assemblies per CBC Table 705.8 and independent utility laterals stubbed to the city main.
