Only if your policy has "blanket" additional insured wording and you have a signed contract that requires it. "Additional insured" means your general contractor (GC) can use your liability policy if they get sued because of your work, and blanket wording covers any customer your signed contract names, with no new paperwork per job. Without blanket wording, nothing is automatic, and each GC has to be added by name with a one page change to your policy called an endorsement. Who this is for: subcontractors who want to know whether their GC is already covered before the certificate goes out.
The short version
- Automatic coverage for your GC comes from blanket wording on your policy. Not every contractor policy has it.
- Blanket wording only works if a written contract requiring it is signed before anything goes wrong.
- Some blanket forms cover your GC only while you are working, not after the job is finished.
- The list of forms at the front of your policy tells you in two minutes whether you have blanket wording.
- If you do not have it, adding it at renewal usually costs little or nothing (illustrative).
What does "automatic" mean on an insurance policy?
Insurance people call it blanket wording. It is an endorsement, one extra page on your policy, that says any customer you agree in a written contract to name is covered as an additional insured. No call to your broker per job. The GC is covered the moment you sign a contract that requires it.
The other kind is scheduled wording. That endorsement lists customers by name. A new GC means a new request to the insurance company and a wait. See blanket vs scheduled additional insured.
How do I know which kind my policy has?
Pull out your declarations page, the front section of your policy with your name, your limits, and your premium. Near the end is a list of every form attached to the policy, often titled "Forms and Endorsements." Look for these.
| Form on your list | What it means in plain English | Is your GC covered automatically? |
|---|---|---|
| CG 20 33 | Blanket additional insured while you are working, for any customer your written contract requires | Yes, during the job only |
| CG 20 38 | Blanket additional insured while you are working, including the owner and others your contract makes you add | Yes, during the job only |
| CG 20 37 with blanket wording typed in the schedule, or an insurance company blanket form that mentions completed operations | Blanket additional insured after the job is finished | Yes, after the job too |
| CG 20 10 | Customers listed by name, while you are working | Only the customers listed on it |
| CG 20 37 with names typed in | Customers listed by name, after the job is finished | Only the customers listed on it |
| None of the above | No additional insured wording on the policy | No |
Insurance companies also write their own blanket forms with their own numbers. The title usually includes the words "Blanket Additional Insured." Deeper reading: additional insured endorsements explained.
What are the catches with automatic coverage?
- You need a signed contract. Blanket wording almost always says the contract must be in writing and signed before the incident. A verbal deal may not count.
- It may stop when the job ends. Some blanket forms cover the GC only during the work. Most GC contracts also want coverage after you finish, because many of the biggest construction claims, especially property damage like leaks and failed work, show up after the job is done.
- The contract has to actually require it. If the subcontract does not say the GC must be an additional insured, the blanket wording does not turn on.
- Your limits are shared. Automatic or not, the GC draws from the same limits you do, and the wording does not cover problems that are only the GC's fault.
What if my policy does not have blanket wording?
Two choices, and many insurance companies will do either one mid term: add blanket wording now, or add an endorsement naming just this GC. The table shows the trade off.
| Fix | Illustrative cost | Time |
|---|---|---|
| Add blanket wording, during the job and after | Often nothing, sometimes a few hundred dollars a year | One to three business days, then automatic for every job |
| Add one named GC, during the job and after | Roughly $50 to $300 per GC | One to three business days, every time |
These figures are illustrative. Your price depends on your trade, payroll, state, and insurance company.
Can I tell from my certificate whether my GC is covered?
Not reliably. A certificate of insurance is a one page summary of your policies, limits, and dates. The "additional insured" check box is a claim that an endorsement exists, not the endorsement itself. That is why the people who check subcontractor insurance paperwork for GCs (their compliance desk) ask for the endorsement pages.
What this looks like in real life
Illustrative example. It is typical of what we see and is not a promise of how any specific situation would be handled.
The setup: A painting contractor in Florida wins a $95,000 subcontract on a hotel renovation. His broker told him two years ago that his policy "covers additional insureds automatically," so he issues a certificate and starts work.
What went wrong: Eleven months after the job closes, a guest slips on a stairwell where the paint finish failed. The hotel owner and the GC are sued and hand the claim to the painter's policy. His blanket form covered the GC only during the work.
What it cost: The GC billed the painter roughly $60,000 under the indemnity clause in the subcontract (a promise to cover the GC's losses). Whether his own policy picks that up depends on its contractual liability wording and state law, and either way it comes out of his own limits after months of arguing. With the completed operations endorsement, the GC would have handed the suit straight to his insurance company.
The fix: "Automatic" is only as good as the form behind it. Read the forms list, or have your broker read it, and confirm it covers your GC during the job and after.
Frequently asked questions
Q: Does my policy automatically cover my GC as an additional insured?
Only if it has blanket additional insured wording and you have a signed contract that requires it. Check the list of forms at the front of your policy, or ask your broker. Without it, each GC has to be added by name.
Q: What is blanket additional insured wording?
An endorsement that covers any customer you have agreed in a written contract to name, with no policy change for each one. It is what makes same day certificates possible.
Q: Does blanket wording cover my GC after the job is done?
Not always. Some blanket forms cover the GC only while you are working. Most GC contracts want protection after the work is finished too, so ask your broker to confirm you have that piece.
Q: Do I need a signed contract for automatic coverage to work?
Yes, in almost every case. Blanket wording needs a written contract that calls for additional insured status, signed before the incident. Get it signed before your crew shows up.
Q: How do I check whether my policy has blanket wording?
Look at the list of forms at the front of your policy. Blanket forms carry titles like Blanket Additional Insured or Automatic Status When Required in Written Construction Agreement.
Q: What if my GC insists on seeing their own name on a policy page?
Send the blanket form with a copy of the signed contract. Together they show the GC is covered. If the GC still pushes back, ask your broker for an endorsement naming them, which often costs nothing.
