Yes, though the options change. When a builder or contractor is no longer in business, potential sources of recovery include the contractor’s commercial general liability insurance policy, which can remain in effect even after the company closes; any bonding the contractor carried; claims against subcontractors who performed the defective work; and in some cases, claims against the developer who hired the contractor. California law also requires contractors to be licensed, and the California Contractors State License Board maintains records that can help identify responsible parties and their insurance history. Do not assume a defunct contractor means a dead end.
