Nakhshab Development & Design Inc. in downtown San Diego's East Village has operated as a vertically integrated design-build firm from its 15th Street headquarters since the company's 2003 founding, holding CSLB General Building licenses 926557 and 910854. The firm's master-builder model consolidates architecture, structural engineering, and construction under one contract—a single-source approach that produced the Mitra Lofts, a nine-unit LEED-certified boutique residential complex completed in 2016 on the same 15th Street block, and that shares the East Village's design-build corridor with AVRP Studios on 16th Street. In-house structural engineering enables Nakhshab to handle earthquake retrofitting, seismic upgrades, and new-construction lateral systems without subcontracting the stamp, compressing the engineering review timeline on projects where OSHPD or residential code triggers would otherwise add weeks. Building permit records show more than 100 permits totaling over $14 million in project value, concentrated in new construction and home-addition categories across San Diego. Electrical and mechanical subconsultant coordination on those ground-up builds follows the same BIM-integrated workflow used by downtown electrical contractors at All City Electric, Inc. in Bankers Hill when sizing service panels and branch circuits against Nakhshab's structural drawings. The firm's most technically demanding projects involve custom single-family residences and small multifamily developments requiring simultaneous architectural design, structural engineering, LEED documentation, and general contracting under a single design-build contract.
