If you run a small business in Texas, sooner or later a general contractor, a commercial landlord, or a big client is going to hand you a contract with a line that says you must name them as an "additional insured" on your general liability policy. For a lot of owners, that phrase lands like a foreign language. What does it mean? Does it cost you anything? And what happens if you sign the job without it?
At TAP Insurance Agency, we walk business owners across Wise County and the DFW metroplex through this request every week. Here is the plain-English version of what an additional insured is, why everyone keeps asking for it, and how to handle it without slowing down your next job.
What "additional insured" actually means
An additional insured is a person or business you add to your own liability policy so they get some of the same protection you carry. Normally, your commercial general liability (CGL) policy only protects you and your business. When you add someone as an additional insured, your policy extends coverage to them for claims that arise out of your work.
Say you are a roofer and you add a general contractor as an additional insured. If a homeowner sues the GC because your crew dropped a bundle of shingles on their car, the GC can turn to your policy for defense and damages instead of burning through their own coverage. That is exactly why they ask for it: they want your insurance to stand behind the work you were hired to do.
Additional insured vs. certificate holder — don't confuse them
This is the single biggest point of confusion we see. A
certificate holder simply receives proof that your policy exists. An
additional insured is actually granted coverage under that policy. Being listed as a certificate holder gives someone a piece of paper; being named as an additional insured gives them real rights if something goes wrong.
If a contract asks for both — and many do — you need the endorsement, not just a certificate. If you want the full breakdown of the paperwork side, read our guide on what a certificate of insurance is in Texas.
Why Texas businesses keep getting asked
Additional insured requests are standard practice in almost any industry where one business hires another. You will run into them if you are:
- A subcontractor working under a general contractor on a build or remodel
- A vendor or service provider working on a client's premises
- A tenant whose commercial lease requires you to protect the property owner
- A landscaper, cleaner, IT provider, or trade doing work at someone else's location
The party requiring it is trying to push liability for your operations back onto your policy — which is reasonable. If your crew causes the loss, their insurer does not want to pay for it. Commercial landlords in particular almost always require it, which is why we cover the property-owner side in our post on
DP-3 landlord insurance for Texas rental property.
How the endorsement works on your policy
Adding an additional insured is done through an endorsement — a formal amendment attached to your CGL policy. Your carrier issues the endorsement, and it becomes part of the contract. The key detail Texas business owners miss: the coverage generally applies only to liability
arising out of your work or operations. It does not turn your policy into a blank check for the other party's own mistakes.
You will also see two common flavors on the endorsement: coverage for ongoing operations (while the job is in progress) and coverage for
completed operations (after you have finished and left). Many contracts, especially in construction, require both. Read the request carefully so you are not caught short after the work wraps up.
Blanket vs. scheduled additional insured
There are two ways to set this up. A
scheduled additional insured names one specific business on the endorsement — fine if you only need to add one party once. A
blanket additional insured endorsement automatically extends coverage to any party you are contractually required to add. If you take on a lot of jobs and constantly get these requests, a blanket endorsement saves you from calling us every time a new contract crosses your desk. We will help you decide which fits your operation and budget.
What it costs
Pricing depends on your carrier, your industry, and whether you go scheduled or blanket, so we will not quote a number here — that is what a real quote is for. What we can tell you is that adding an additional insured is usually an inexpensive change, and it is almost always cheaper than losing a job because your paperwork was not in order. Because it is tied to your CGL, it often lives inside a broader policy like a
business owners policy (BOP), which bundles liability and property coverage for small businesses.
Common mistakes Texas small businesses make
A few traps trip owners up again and again:
- Sending a certificate when the contract wanted an endorsement. The job stalls, and you scramble at the last minute.
- Forgetting completed-operations coverage. The GC needs protection after the build is done, not just during it.
- Assuming the request is optional. If you start work without it, you may be in breach of contract — and personally on the hook if a claim hits.
- Waiting until the morning of the job. Endorsements take a little time to issue. Give your agent a heads-up as soon as you see the requirement.
