Why build an ADU in Loma Linda.
Loma Linda has one of the strongest medical-rental tenant pools in the entire Inland Empire. The Medical Center, Children's Hospital, School of Medicine, and Veterans Affairs Healthcare System all draw a continuous stream of residents, fellows, students, and traveling medical professionals who need furnished or unfurnished one-bedroom housing on long-term leases. ADU rents in Loma Linda for a 600–800 sq ft one-bedroom unit consistently track above comparable units in Redlands or San Bernardino. The city's compact footprint also means most ADUs are walkable to campus and the hospital, which commands a meaningful rent premium. For homeowners who already live in Loma Linda and own land outright, a detached ADU is one of the highest-yield real estate moves available in the region.
