California is facing one of the most severe housing affordability crises in the country. Housing costs have risen far faster than incomes, pushing homeownership and stable rental housing out of reach for middle- and working-class households across the state.
In response to these structural pressures, Manufactured Home Inspection, Inc. (MHI), operating as BuiltADU, has emerged as a vertically integrated manufactured housing platform delivering lower-cost housing faster and with greater cost certainty than traditional stick-built construction. Based in Southern California, MHI works with homeowners, developers, and municipalities to deploy manufactured housing across single-family lots, backyard ADUs, and small-scale multifamily communities.
