California AB1903 amends civil code to enhance construction standards for residential structures.

California AB1903 amends the Civil Code to strengthen construction standards for residential structures. It mandates that structures must comply with design criteria for earthquake and wind load resistance, and prohibits soil and engineered retaining walls from causing damage. Hardscape installations must prevent water or soil erosion. Plumbing, sewer, and utility systems must operate properly and not leak or corrode. Foundations, load-bearing components, and slabs must not cause structural unsafety.
