6 COI Mistakes That Cost Florida Subcontractors Jobs
Your certificate of insurance is the first thing a general contractor checks — and the fastest way to lose a job. Here are the 6 most common COI mistakes Florida subcontractors make and how to fix them.

You bid the job. Your price was right. The GC wants to bring you on. Then they ask for your certificate of insurance — and something on it kills the deal.
This happens constantly in Florida construction. A subcontractor who does excellent work and bids competitively loses jobs because their COI doesn't meet the GC's requirements, their limits are too low, their endorsements are missing, or their workers comp situation raises red flags. The worst part: most of these issues take less than a week to fix, but subs don't find out until they're about to lose a contract.
Here are the six COI mistakes we see Florida subcontractors make most often — and exactly how to prevent each one.
Key Takeaway
- A COI is an informational document only — it doesn't confer or guarantee coverage
- Missing CG 20 37 (completed operations additional insured) is the single most common deal-killer
- GCs can reject your workers comp exemption even if the state approved it
- Lapsed coverage that appears active on an old COI creates liability for everyone
- Auto insurance limits below $1 million combined single limit will disqualify you from most commercial jobs
- Your agent should be able to turn around a corrected COI in 24–48 hours — but don't wait until the last day
1. Missing Additional Insured Endorsement for Completed Operations
This is the number one COI mistake in Florida construction, and it's the one most likely to cost you a job on the spot.
When a GC requires you to name them as an additional insured, they need protection for two phases of your work:
- Ongoing operations (while you're actively working) — covered by CG 20 10
- Completed operations (after you finish and leave) — covered by CG 20 37
Most subcontractors have CG 20 10 on their policy. Far fewer have CG 20 37. The result: the GC is listed as an additional insured while you're on site, but the moment you finish your scope and leave, that protection vanishes.
Why GCs Are Getting Strict About CG 20 37
Under Florida Statute 95.11, the statute of limitations for construction defect claims is four years from discovery, with a seven-year statute of repose. That means a defect in your plumbing, electrical, or roofing work can generate a lawsuit years after you've left the site. Without CG 20 37, the GC has zero additional insured protection for that entire exposure window.
How This Plays Out on a Real Job
An electrical sub finishes rough-in on a commercial buildout in Jacksonville. Eighteen months later, a wiring defect causes a fire that damages two adjacent tenant spaces. The building owner sues the GC. The GC tenders the claim to the sub's carrier under the additional insured endorsement.
With CG 20 10 only: Claim denied — the work was completed, and CG 20 10 only covers ongoing operations.
With CG 20 10 + CG 20 37: Claim accepted — CG 20 37 extends additional insured coverage to completed operations.
The GC now has a policy: no CG 20 37, no contract.
The fix: Ask your agent to add CG 20 37 to your general liability policy. The cost is typically modest — often a few hundred dollars annually. It's one of the cheapest ways to make yourself more competitive for commercial work.

2. GL Limits That Don't Meet Contract Requirements
Most Florida GC contracts for commercial work require subcontractors to carry general liability at $1,000,000 per occurrence / $2,000,000 aggregate at minimum. Government contracts and larger commercial projects often require $2,000,000 per occurrence / $5,000,000 aggregate — or evidence of an umbrella policy that reaches those limits.
If your COI shows $500,000 per occurrence or $1,000,000 aggregate, you're automatically disqualified from a significant portion of the commercial market.
The Umbrella Solution
If your GL policy limits are $1M/$2M and a contract requires $2M/$5M, you don't necessarily need to increase your primary GL limits. A commercial umbrella policy sits above your GL (and often your auto and workers comp employer's liability) and provides the additional limits needed. An umbrella for a small to mid-size sub typically runs $1,500–$4,000/year for $1M–$2M in additional limits — far less than the cost of losing a single commercial contract.
The fix: Know the standard requirements in your market segment. If you're bidding commercial work, carry at least $1M/$2M on your GL. If you're pursuing larger projects or government work, get an umbrella to reach $2M/$5M. Have your agent prepare COIs at both limit levels so you're ready when the RFP comes in.
3. Workers Comp Exemptions That GCs Won't Accept
Florida law allows up to three corporate officers of a construction company who own at least 10% of the company to exempt themselves from workers compensation under Florida Statute 440.05. Many small subcontractors — especially sole proprietors operating through an S-corp or LLC — use this exemption to avoid carrying workers comp.
The problem: general contractors are not required to accept your exemption.
The Exemption Rejection
A two-person drywall sub (the owner and one employee) bids a commercial interior job. The owner has a valid workers comp exemption. The employee is covered. The GC rejects the COI because their risk management policy requires all workers on site — including exempted officers — to be covered by workers comp. The sub loses the bid.
Reason: If the exempted owner is injured on the GC's site, the GC may face liability exposure that their own carrier could push back on. The GC's insurer doesn't want the risk, so the GC doesn't either.
This is increasingly common on commercial, multi-family, and government projects. The larger the project, the more likely the GC requires full workers comp coverage regardless of exemption status.
The fix: If you're pursuing commercial work, consider carrying workers comp on yourself even if you have a valid exemption. The additional premium for an exempted officer to add themselves back to the policy is often $1,000–$3,000/year — and it opens the door to contracts that would otherwise be closed.
Pro Tip
If you do maintain a workers comp exemption, make sure your exemption certificate is current and active with the Florida Division of Workers' Compensation. Exemptions expire every two years. An expired exemption means you're operating without any workers comp status at all — not covered, and not properly exempted. GCs check.
4. Lapsed Policies Behind an Active-Looking COI
A certificate of insurance is a snapshot in time. It reflects what was true on the day it was issued. Policies can be cancelled, non-renewed, or lapsed after the COI is generated — and the old certificate will still show active dates.
COIs Don't Update Automatically
Certificates of insurance are informational documents only — they do not confer, alter, or extend coverage. If your policy lapses on March 1 but your COI shows an expiration date of September 30, anyone relying on that COI believes you're covered when you're not. In Florida construction, this creates serious exposure for both the sub and the GC.
How this happens:
- Sub lets a policy lapse for non-payment and doesn't tell the GC
- Sub switches carriers mid-policy and the old COI is still on file
- Sub's policy is non-renewed by the carrier and the sub operates on the old certificate while shopping for a replacement
- Sub's carrier issues a cancellation notice, but it goes to an old address
The consequences are severe. If you cause a claim while operating on a lapsed policy:
- Your carrier denies the claim (no active coverage)
- The GC's carrier may deny it too (they relied on your COI)
- You're personally liable — and potentially facing a stop-work order if workers comp was lapsed
The fix: Set up automatic payment on every policy. Give your agent a current email and mailing address so cancellation notices reach you. When you renew or switch carriers, immediately request updated COIs for every GC you're working with. Don't assume the old certificate is fine — it isn't.
5. Commercial Auto Limits Below Contract Minimums
Subcontractors focus on GL and workers comp and forget about auto. But your trucks and work vehicles are on the road every day — hauling materials, pulling trailers, driving between sites — and commercial auto is a separate requirement on most GC contracts.
Standard GC contract requirements for subcontractor commercial auto:
- $1,000,000 combined single limit (CSL) for bodily injury and property damage
- Hired and non-owned auto coverage (for employees using personal vehicles for work)
- Certificate holder listed on the auto policy
Many small subs carry the Florida minimum auto coverage or a $500,000 CSL — which doesn't meet commercial contract requirements.
Auto Limits Kill a Contract
A plumbing sub in North Florida carries $300,000/$500,000 auto limits. They bid a $200,000 commercial plumbing job. The GC requires $1M CSL on commercial auto. The sub can't produce a COI with the right limits and loses the job.
Cost to upgrade from $300K/$500K to $1M CSL: approximately $400–$800/year in additional premium.
Revenue lost from the one job: $200,000.
The fix: Carry $1M CSL on your commercial auto from the start. The incremental cost of higher limits is minimal compared to the contracts you'll lose without them. And add hired and non-owned auto — if your crew drives personal vehicles for any work purpose, this coverage is essential.

6. Not Keeping Your Agent in the Loop on New Contract Requirements
This is the mistake behind most of the other mistakes on this list. A sub gets a new contract opportunity, sees the insurance requirements in the bid package, and either ignores them, assumes they're already covered, or panics the day before the deadline.
Your insurance agent should be one of the first calls you make when you're pursuing a new contract — not the last. A good agent can:
- Review the contract's insurance requirements and compare them to your current coverages
- Identify gaps (missing endorsements, insufficient limits, expired certificates)
- Request endorsement changes from your carrier before the deadline
- Issue updated COIs with the correct additional insured language, project descriptions, and limits
- Advise on whether an umbrella makes more sense than increasing primary limits
Pro Tip
When you get a bid package, photograph or scan the insurance requirements section and send it to your agent immediately — even before you've decided whether to bid. Your agent can tell you within an hour whether your current program meets the requirements or what changes are needed. This avoids last-minute scrambles that can delay your start date or kill the deal entirely.
Key Takeaway
Your COI is the first impression a GC has of your business. Six mistakes that cost Florida subcontractors jobs: (1) missing CG 20 37 for completed operations, (2) GL limits below the $1M/$2M contract standard, (3) workers comp exemptions that commercial GCs won't accept, (4) lapsed policies behind outdated certificates, (5) commercial auto below $1M CSL, and (6) not involving your agent early enough to fix issues before deadlines. Every one of these is fixable — usually for a few hundred to a few thousand dollars a year. The jobs you lose by not fixing them cost far more.
