California's statewide ADU law (AB 68 + SB 9) requires San Diego to permit ADUs on most single-family residential lots. HUD-certified manufactured homes qualify. SD County and SD City have slightly different rules; permit timelines run 3-6 months typical. Coastal Commission review areas add 4-8 weeks. All CA-delivered homes ship with earthquake-rated tie-down systems and Title 24 energy code compliance as standard.

Top destinations: Chula Vista, El Cajon, Escondido, and Oceanside for ADU placements; East County rural (Alpine, Ramona, Julian) for larger acreage; North County coastal (Carlsbad, Encinitas) for smaller premium ADUs; and Imperial Beach for shore-area cottages.
California-spec base price starts at $52,900. Most SD ADU buyers invest $95,000–$160,000 all-in including Texas-to-SD freight, California-spec engineering, ADU permit + survey ($8K–$15K), foundation, and utility hookup. Still dramatically below the $300K–$500K cost of a site-built SD backyard ADU.
