DR Build ADU specialist in Bonita focuses exclusively on accessory dwelling unit construction from its Bonita Farms Court headquarters in the 91902 area near Bonita Golf Club. Each ADU project moves through site evaluation, architectural drafting, city permit filing, and full construction—with plumbing rough-ins and fixture installation subcontracted to trade firms such as Primo Plumbing for code-compliant water and waste tie-ins. The company builds both detached ADUs and junior ADU conversions within existing footprints, addressing California's AB 68 and SB 13 provisions that eliminated many local barriers to secondary unit permitting. Finished units include independent HVAC, electrical metering, and exterior hardscape, with native-plant perimeter screening often sourced from nearby suppliers such as Bonita Creek Nursery along the Sweetwater Road nursery corridor. The most complex builds involve two-story detached ADUs with separate utility laterals, 200-amp sub-panels, and fire-rated exterior wall assemblies meeting CBC Chapter 7A wildland-urban interface requirements for Bonita's hillside parcels.
