Joza Design Group in Chula Vista's Third Avenue Village has produced residential and commercial architectural plans since its 2000 founding, completing more than 450 projects across San Diego County. Custom home designs, room additions, remodels, and tenant improvements represent the studio's core output — an ADU-and-renovation scope that overlaps with the accessory dwelling unit conversions handled by ADUs & Garage Conversions | Sprawl Design. The firm also provides structural engineering coordination, pairing architectural drawings with stamped structural calculations for permit-ready submittals to the City of Chula Vista Development Services Department. Construction document packages move from design to build phase through general contractors on the Broadway corridor, where Fausto Construction Inc. converts residential and commercial plans into permitted structures. Title 24 energy compliance reports, California Building Code egress calculations, and ADA accessibility reviews accompany every submittal, ensuring plan-check readiness across jurisdictions in San Diego County.
