Contractor reviewing an insurance certificate at a job-site tailgate
The short version
  • $1M per occurrence / $2M aggregate is the contract minimum, not a risk-based decision.
  • Doubling your primary limit is the expensive way to buy limits; an umbrella is usually 3–5x cheaper per dollar of coverage.
  • Without a per-project aggregate, one bad claim can exhaust the limit protecting every other job you have running.
  • Products-completed operations has to survive New Jersey's 10-year statute of repose — after the job is done and paid.

$1M/$2M is a floor, not a target

Almost every commercial contract in New Jersey requires $1,000,000 per occurrence and $2,000,000 aggregate General Liability. So contractors buy exactly that, hand over the certificate, and never think about it again. The number wasn't chosen because it matches your exposure — it was chosen because it's what the GC's form says.

Here's the problem with treating a contract minimum as a coverage decision. A single serious bodily-injury claim — a fall from a ladder you set, a fire traced to your torch work, a struck-by involving your equipment — routinely settles above $1,000,000 once medical costs, lost future earnings and a spouse's loss-of-consortium claim are in the same demand. Defense costs may erode that limit too, depending on your form. When the verdict exceeds the limit, the excess is a judgment against your business, and in New Jersey a judgment against an LLC that can't pay it is a business that stops existing.

The right question isn't "what does the contract require?" It's "what's the largest single loss my work can realistically cause, and can my program absorb it?" A drywall contractor working occupied office space and an excavator trenching next to a gas main have wildly different answers, and they are frequently carrying identical limits.

The umbrella math (why doubling your GL is the wrong move)

Once a contractor decides $1M isn't enough, the instinct is to raise the primary General Liability to $2M/$4M. That's the expensive path. The primary layer is where nearly all claims land, so the carrier prices those first dollars assuming they'll get used. Doubling the primary limit can add 40–70% to your GL premium.

A commercial umbrella prices the opposite way. It only pays after the underlying limit is exhausted, which is rare, so each dollar of umbrella limit costs a fraction of a dollar of primary limit. In practice, for a clean small-to-mid NJ contractor:

  • A $1M umbrella often runs roughly $500–$1,000 per year.
  • A $2M umbrella often runs roughly $700–$1,400 per year.
  • A $5M umbrella is frequently under $3,000 per year for the right class.

Those are ranges, not quotes — trade, payroll, loss history and whether you do any New York work move them substantially. But the structural point holds: $1M GL plus a $2M umbrella gives you $3M of protection for far less than a $2M/$4M primary gives you $2M.

One critical detail: an umbrella sits over scheduled underlying policies. If your Commercial Auto or Employers Liability limits are below what the umbrella requires as underlying, there's a gap the umbrella won't drop down to fill. This is why quoting the lines together matters — the stack has to be coordinated, not assembled one policy at a time by three different agents.

Per-project aggregate: the endorsement most contractors don't have

Your $2,000,000 aggregate is not per job. It's the total the policy will pay across every claim in the policy year, on every project. Finish four jobs, have a bad claim on the first one that pays $1.8M, and the remaining three projects are protected by $200,000 for the rest of the term.

A per-project aggregate endorsement resets the aggregate limit separately for each project. Most carriers offer it, many contractors don't have it, and a growing number of GCs and owners now require it explicitly in the insurance exhibit — which means the certificate you send may get rejected without it.

Check your declarations page for wording like "General Aggregate Limit applies per project" or endorsement CG 25 03. If it isn't there, ask what it costs. On most accounts it's a modest charge relative to what it protects.

Products-completed operations and the ten-year tail

The products-completed operations aggregate is the limit that responds after your work is finished — the defect claim, the leak that shows up in year four, the deck that fails in year seven. It's a separate aggregate from your general aggregate, and it is the limit most likely to matter years after you've forgotten the job.

New Jersey's construction-defect statute of repose allows claims for up to ten years after substantial completion. General Liability is an occurrence form, so the policy in force when the damage occurred generally responds — but only if you were insured then and the completed-operations coverage wasn't stripped out. Two things regularly go wrong:

  • Completed operations gets excluded. Some hard-to-place classes (roofing, certain residential work, EIFS) are quoted with a completed-operations exclusion to make the price work. Contractors sign it without noticing that they just deleted coverage for the claims their trade is most likely to have.
  • Coverage lapses. Contractors who retire, take a year off, or switch to a cheaper policy mid-tail leave a hole. If the damage occurs during an uninsured period, there's no policy behind it.

Read your declarations for a products-completed operations aggregate that isn't $0 and isn't excluded by endorsement. That single line is worth more scrutiny than the headline occurrence limit.

What being underinsured actually costs

The cost isn't theoretical, and it usually isn't the verdict itself. It's the sequence that follows:

  1. The claim exceeds your limit. Your carrier tenders its limit and its duty to defend ends.
  2. You pay your own defense from that point, at $300–$600 an hour.
  3. The plaintiff pursues the business's assets — receivables, equipment, trucks — and, depending on entity structure and the allegations, sometimes personal assets.
  4. Your next renewal reflects a large loss. Some markets decline you outright. Others quote with restrictions.
  5. GCs who see the loss history in a prequalification questionnaire quietly stop calling.

The premium difference between a $1M program and a $3M program is typically a few hundred to a couple of thousand dollars a year. The difference in outcome on a severe claim is the business.

How to check your own limits in five minutes

Pull your declarations page and confirm five things:

  • Each occurrence limit — $1M is the minimum; consider more if your work touches occupied buildings, height, fire or heavy equipment.
  • General aggregate — and whether it applies per project.
  • Products-completed operations aggregate — present, not excluded, and not shared down to a token number.
  • Whether defense costs are inside or outside the limit — inside-the-limit defense quietly shrinks your coverage as the file runs.
  • Umbrella schedule of underlying — the underlying limits listed must match what you actually carry on GL, Auto and Employers Liability.

If any of those five surprises you, that's the conversation to have before your next renewal, not after a claim.

Frequently asked

Is $1 million enough General Liability for a NJ contractor?
It satisfies most contracts, and NJ home improvement contractor registration only requires $500,000 — but adequacy depends on the severity your work can cause. A serious injury claim can exceed $1M on its own. Most contractors are better served by $1M primary plus a $2M or larger umbrella than by $1M alone.
Is it cheaper to raise my GL limit or add an umbrella?
An umbrella is almost always cheaper per dollar of limit. Primary limits are priced for dollars that get used; umbrella limits are priced for the rare exhaustion of the underlying policy. $1M GL plus $2M umbrella typically costs less than a $2M/$4M primary.
What is a per-project aggregate and do I need it?
It resets your aggregate limit separately for each project instead of sharing one aggregate across every job in the policy year. Without it, one large claim can leave your other active jobs nearly unprotected. Many GCs now require it by endorsement.
How long do I need to keep General Liability after finishing a job?
New Jersey's statute of repose allows construction-defect claims for up to 10 years after substantial completion. Because General Liability is occurrence-based, the policy in force when the damage occurred responds — so gaps in coverage during that decade create uninsured exposure.
Do defense costs come out of my limit?
On most standard contractor General Liability forms, defense is paid in addition to the limit. On some surplus-lines and hard-to-place forms it's inside the limit, which means legal fees erode the money available to pay the claim. Check your declarations page — it makes a large practical difference.
