NJ Contractor Insurance Requirements — The Complete Guide

Three sources of "required"

When a contractor asks "what insurance do I need," the honest answer is: it depends who's doing the requiring. In NJ there are three sources, and they stack.

The state. NJ requires Workers Compensation for any employee — including most corporate officers, who are presumed covered unless they specifically elect out. This is different from PA and NY, and it trips up contractors who move here. There's no payroll threshold; one employee triggers the requirement.

Your contracts. This is where most of the real requirements live. A GC's subcontract, a property owner's master agreement, a property manager's vendor packet — each spells out limits and endorsements. The typical commercial requirement is $1M/$2M General Liability with additional insured, primary & non-contributory, waiver of subrogation, and 30-day notice of cancellation. Public work adds bonding and sometimes prevailing-wage documentation.

Lenders and licensing. If you finance equipment or vehicles, the lender requires physical damage coverage. NJ Home Improvement Contractor (HIC) registration carries its own commercial general liability requirement. See our piece on HIC registration.

The practical floor for an NJ contractor

• GL at $1M/$2M, structured with the endorsements your contracts demand.
• Workers Comp if you have any employee.
• Commercial Auto on any vehicle used for business — personal auto excludes it.
• Tools & Equipment because standard property doesn't cover tools off premises.
• A Commercial Umbrella sized to your severity exposure.
• Builders Risk on projects where you carry the structure.

The point of quoting these together — in one intake — is that they coordinate. The umbrella attaches cleanly only if the underlying GL, auto, and EL limits line up.

Authoritative sources

For the underlying rules, go to the source: the NJ Department of Banking and Insurance (DOBI), the NJ Division of Consumer Affairs (which administers HIC registration), and the NJ Department of Labor for Workers Comp. We'll translate any of it into what it means for your program.
