Why the three-trade rule for O&P denials isn't law
Carriers deny General Contractor's Overhead and Profit by citing a three-trade minimum that appears in no policy, statute, or regulation. The gap between what's customary and what's actually required is where most contractors leave money on the table.
Carriers deny General Contractor's Overhead and Profit on the theory that it only applies when three or more trades are coordinated on a job. Ask them to show you where that's written into a policy, a statute, or a regulation, and they can't, because it isn't. It's an adjusting convention, passed down inside claims departments the way house rules get passed down in any organization, until everyone treats it like the law even though nobody can point to where it's codified. That gap between "widely used" and "actually required" is the whole ballgame, and most contractors never push on it.
What the three-trade rule actually gets wrong
O&P isn't a reward for touching a certain number of trades. It's compensation for the coordination, the sequencing, and the liability a general contractor carries on a job, whether that job involves two trades or six. A single-trade job with real scheduling complexity, real subcontractor liability exposure, and real oversight can justify O&P. A four-trade job with no actual coordination, where every sub showed up and did their piece independently, might not. The trade count is a proxy carriers reach for because it's easy to count. It was never the actual test, and where contractors have pushed back with real documentation of what they coordinated, courts have sided with them, trade count or not.
Document what you coordinated, not why you deserve it
So the fix isn't arguing "we deserve O&P" as a principle. Every for-profit business is entitled to build overhead and profit into its price, and no court has ever said otherwise. That argument wins nothing, because the carrier isn't disputing the principle. They're disputing your specific file. What they respond to is documentation: the sequencing you managed, the subs you supervised, the liability you carried, the decisions only a GC on that job could have made. Write that down, on every job, the way you'd write down a moisture reading. If it isn't on paper, it doesn't exist to the adjuster reading your file, and the three-trade rule becomes the only thing left for them to point to.
The second problem: your real number vs. the software default
The second problem is quieter, and it's one contractors do to themselves. "General Contractor's Overhead and Profit" is a line item in Xactimate. It is not an IRS category, and it is not a standard accounting classification. Your books don't separate "GC overhead" from regular overhead, because there's no such split in how a business actually operates or how the tax code treats it. You report one number: your real overhead and profit, the number your accountant defends every year. Xactimate expects a round percentage, usually ten and ten, or some close variation, and that expectation has nothing to do with your actual cost structure.
When your real number doesn't match the software's default, that mismatch becomes ammunition. Not because your business doesn't deserve to price in overhead and profit, but because you showed up to the negotiation without your own number, and let the software's number stand in for it. An adjuster who sees a contractor using the default percentage assumes nobody checked it. An adjuster who sees a contractor cite their own tax-consistent figure, and defend it, is dealing with someone who's done the work.
Put the two together and the pattern is obvious. Carriers deny O&P using a rule that isn't law, and contractors let them get away with it by showing up with a software default instead of a defended number and a documented coordination record. Neither failure is about entitlement. Both are about preparation. The contractor who can produce the actual sequencing and liability they carried on a specific job, and the actual overhead and profit percentage their business runs on independent of what Xactimate assumes, is the contractor carriers stop testing with the three-trade rule, because there's nothing left in the file for the rule to work on.
That's the whole fix: document what you actually coordinated, and know your real number before the adjuster asks for it.

Questions owners actually ask
Is the three-trade rule written into any insurance policy?
No. It doesn't appear in standard policy language, state insurance statutes, or industry regulation. It functions as an internal adjusting convention that carriers apply consistently, but it isn't a legal requirement contractors are bound by.
Does a job need multiple trades to qualify for O&P?
The relevant question is whether the job required a general contractor's coordination, sequencing, and liability exposure, not how many trades were on site. A single-trade job with real complexity can justify O&P; a multi-trade job with no real coordination might not.
Why does my Xactimate O&P percentage matter if it's just default software settings?
Because carriers use a mismatch between your invoiced O&P and your defensible, tax-consistent number as a reason to question the whole line item. Knowing and being able to produce your real number removes that opening.
NanoForce's Claims-to-Cash system audits every file's documentation before submission, including whether the coordination and liability record supports the O&P claimed on that specific job, so the file doesn't rely on carriers overlooking a gap that was never closed.
