Manufactured Home Foundation Engineering (HUD) in Antioch: Local Conditions That Matter
East Contra Costa soils include clay, sand, and alluvial deposits. Foundation assessment is important. Antioch is in a moderate-to-high seismic zone. Seismic design is required per California Building Code. Manufactured home foundations in Antioch must satisfy both HUD's national standard and California's registration requirements — and the design has to fit the soil actually under your pad.
