California's Retention Reform On Private Construction Projects

Retention has long been a contentious issue in California construction. Traditionally, owners withheld retention of 10% from each progress payment until completion, arguing it was necessary to ensure performance, quality and timely delivery. Contractors and subcontractors, however, often struggled with cash flow, payroll, and material costs while waiting months—sometimes even years—for withheld retention.

Recognizing the financial challenges contractors and subcontractors face, the California legislature passed Senate Bill 61 ("SB 61"), now codified under California Civil Code Section 8811 and effective January 1, 2026, limiting retention to 5% on private works of improvement, aligning with the public works standard in place since 2012. The law's intent is clear—ease financial strain on contractors and subcontractors while still providing owners with security (albeit reduced) with respect to project completion.
