A client, a general contractor or a landlord has asked for more liability than your policy carries. A commercial umbrella adds limits above the business policies you already hold — but only above the ones it schedules, and only on the terms its own form sets.
This is the business version. The one that protects a family’s home and cars is a personal umbrella insurance policy — different underlying policies, different form, and not interchangeable with this one.
Start here
Almost nobody buys added limits because they woke up wanting them. Somebody put a figure in a document, and the useful first move is to read the whole insurance article rather than the number in it. A real one usually settles four things at once: which coverages it names, what limit each has to carry, whether an excess layer may be counted toward the total, and what else has to be arranged — additional insured status, a waiver of subrogation, primary and non-contributory wording, notice of cancellation.
The City of Houston’s own standard procurement terms are a useful worked example: they list general liability, auto, employers liability and professional liability separately, and then state an excess or umbrella layer of their own. That is one contract published by one buyer — not a rule for Houston, and not a template for whatever landed in your inbox. It is worth reading precisely because it shows how specific a serious requirement gets.
A limit is also not the only thing a clause can require, and agreeing to one does not satisfy the rest. Bring the document. Reading it is the fastest part of this.

What sits underneath
A layer is defined by what it attaches to. These are the policies it commonly attaches to — commonly, not universally, because the schedule on the actual policy is what decides, and a coverage that is not scheduled is not underneath anything.
Usually the first layer
The premises-and-operations liability policy most contracts start from. A business owner’s policy can supply this layer through its own liability section rather than a separate general liability policy.
The vehicles that work
The liability half of the vehicle policy, not the physical-damage half. A layer that schedules auto liability adds limits to that side only.
Not the statutory benefits
The liability part that sits alongside a workers’ compensation policy — the suits brought against an employer rather than the benefits paid to an injured worker. This distinction has its own section below because it is the one people get wrong.
Insurers commonly require specified limits on those policies before a layer will attach, and some require their own primary policies underneath. Those requirements are set by the program, and they vary between them.

Four words, used loosely
Most of the confusion in this subject is vocabulary. These four words get used interchangeably in conversation and mean quite different things in a claim.
The practical consequence is the one people find hardest to accept: a layer above a policy that never covered the event is not a second opinion. It responds on its own terms, and its own terms may exclude the same thing.

A distinction worth holding
Texas workers’ compensation provides medical and lost-wage benefits to covered employees. Those benefits are statutory and they are not an umbrella layer — nothing sits above them in this sense. What can sit underneath a layer is employers liability, the coverage that answers suits brought against the employer.
They travel on the same policy and get spoken of as one thing, which is exactly why a contract asking for excess over employers liability is not asking about benefits at all. Whether to carry compensation coverage in the first place is a separate Texas decision with its own consequences, and it belongs on our workers’ compensation insurance page.

An old figure still circulating
Search for required underlying limits in Texas and an old departmental bulletin from 1997 is still likely to come back, carrying what look like universal automobile minimums. Treat it as historical. The rule behind it, 28 TAC §5.1201, was repealed effective 21 July 2021, on the department’s own stated grounds that statutory changes had made it obsolete.
What sets underlying limits today is the insurer’s program requirements, the form itself, and the contract in front of you. Commercial umbrella and excess forms and rates are treated as an exempt commercial line, which is a further reason the answer lives at form level rather than in a published schedule.
This matters beyond pedantry: a business that sets its limits from a repealed rule can believe it has met a requirement it has not met, and find out at the certificate stage or later.

Not automatically included
Professional liability, cyber, management liability, employment practices, pollution, liquor and garage exposures are not automatically scheduled under a commercial umbrella, and many forms exclude them by name. A contract asking for higher limits on one of those is usually asking about that policy, or about a layer written specifically over it.
Assuming otherwise is a quiet and expensive mistake, because it looks solved on a certificate. If a requirement names a specialty coverage, treat it as its own line of the review rather than something the umbrella already carries.
Before anyone says it fits
Whether a proposed structure actually meets a requirement is a form question, and these are the items that decide it:
And one thing at the end of it: a certificate cannot alter, amend or extend the coverage a policy provides. It evidences what is there. If the contract requires a limit or an endorsement, the policy and its endorsements have to actually provide it — which is why the review happens before the certificate, not after.

No obligation
The fastest version of this conversation is the contract clause plus your current declarations pages. From those two things we can map what you carry, what the document is actually asking for, and where the gap is — before anyone talks about a layer.

No. It sits above it. An umbrella or excess layer generally requires the underlying policies to be in force at stated limits, and a lapse underneath can leave a gap the layer above was never meant to fill. The base policies stay; the layer adds to them.
They overlap and they are not interchangeable. Excess liability commonly adds limits above specified coverage without broadening it. An umbrella may reach some exposures the primary policy does not, where its own form does not exclude them. Market usage of both labels varies enough that the only reliable comparison is between the two actual forms.
Commonly general liability, commercial auto liability and employers liability, and a business owner’s policy can supply the general liability layer through its own liability section. What matters is not the common list but the schedule on the actual policy — a coverage that is not scheduled is not underneath anything.
Statutory workers’ compensation benefits — the medical and lost-wage benefits paid to a covered employee — are not an umbrella layer. Employers liability, which sits alongside that policy and answers suits against the employer, commonly can be. The two are routinely spoken of as one thing and they are not.
No. Specialty lines are not automatically scheduled under a commercial umbrella, and many forms exclude them outright. If a contract requires higher limits on a specialty policy, that is usually a question for that policy or for a layer written specifically over it — not an assumption that the umbrella already reaches it.
Sometimes, and only the contract can say. Some contracts accept a primary limit plus an excess layer as a combined total; others set a minimum on the primary policy itself, or name which coverages the excess has to sit over. Read the insurance article before assuming a structure will be accepted — and note that agreeing to a limit is not the same as meeting the additional-insured, waiver and notice terms in the same clause.
There is no current statewide chart. Texas repealed its old umbrella rule, 28 TAC §5.1201, effective 21 July 2021, on the grounds that statutory changes had made it obsolete — and an older departmental bulletin carrying apparently universal figures is still circulating. Treat that as historical. Today the insurer’s own program requirements, the form, and the contract are what set the underlying limits.
No, and this is the most common misunderstanding in the subject. A denial upstairs is usually a coverage decision, not an exhausted limit. If the underlying policy did not cover the event, the layer above responds on its own terms — which may exclude the same thing. Exhausted and excluded are different situations with different answers.
No. A certificate evidences insurance; it cannot alter, amend or extend the coverage the policy provides. If a contract requires a limit or an endorsement, the policy and its endorsements have to actually provide it — the certificate just reports what is there.
