Requires that definition of occurrence in certain property damage liability insurance policies include coverage for faulty workmanship.

New Jersey's bill A 599 requires commercial liability insurance policies for contractors and construction professionals to explicitly define "occurrence" to include property damage from faulty workmanship. This affects builders, remodelers, and construction companies who purchase such insurance for projects. The policy must clearly cover damage caused by poor work as part of "occurrence" - resolving past court disputes over whether such damage qualified for coverage. Policies cannot be delivered, issued, or renewed in New Jersey after the 90-day effective date without this definition.
