New Residential Construction Insurance
Why Completed Operations Coverage Is Non-Negotiable

Of every kind of contractor we insure, new residential builders sit near the top of the risk ladder, and it's not because they're careless. It's because of what they're building, who ends up living in it, and how long it can take for a problem to surface after the last coat of paint dries. A framing crew, a roofer, and a strip-mall renovation contractor can all carry general liability, but the exposure sitting underneath a home builder's policy looks nothing like theirs, and the coverage has to be built to match it, not borrowed from a generic contractor template.

This is the coverage conversation we have most often with builders: not "do you have general liability," but "does your policy actually respond three, five, or ten years from now when the claim you didn't see coming finally shows up." That question is really about one coverage in particular, completed operations, and about whether your policy is written on a form that can even answer it. Let's walk through why.

Why New Residential Construction Carries More Risk

Underwriters treat new residential construction as a higher-hazard class than most commercial contracting, and the reasoning holds up when you actually break it down piece by piece.

People will live there, permanently, for decades

A commercial tenant improvement gets inspected, occupied by a business, and used during business hours. A house gets occupied by a family, every day, for the next 30 to 50 years. A foundation crack, a roof that leaks in year four, or plumbing behind a wall that was never properly sealed doesn't just cause an inconvenience; it can force a family out of their home for repairs, trigger a mold remediation, or in the worst cases become a structural or habitability issue. Habitational claims tend to run more severe than commercial ones because the standard for "made whole" is a fully livable home, not a functioning storefront.

Multiple trades stack on top of each other, fast

A single new-build home moves through excavation, foundation, framing, roofing, electrical, plumbing, HVAC, insulation, drywall, and finish trades, often overlapping, often with a different subcontractor for each phase. When something goes wrong later, whether it's the framer's structural work, the plumber's rough-in, or the roofer's flashing, figuring out which trade's work actually caused the problem can be genuinely difficult, and it's common for more than one policy to end up involved in the same claim.

The biggest defects don't show up until after the work is done

Foundation settling, water intrusion, mold growth behind finished walls, and structural issues rarely announce themselves on the day the crew leaves the site. They surface months or years later, after drywall is up, after the family has moved in, after the builder has moved on to the next project. That time lag is exactly what makes completed operations coverage, discussed in detail below, the single most important piece of a residential builder's general liability policy.

Active job sites are genuinely dangerous, and attract people who shouldn't be there

Open excavations, unfinished stairwells without railings, exposed wiring, scaffolding, and stacks of building materials all sit on a site that, unlike a fenced commercial lot, often borders a residential neighborhood full of curious kids. Courts have long treated an active construction site as an "attractive nuisance," meaning a builder can be held to a higher standard of care for keeping trespassers, especially children, safe, even if they weren't invited onto the site.

Weather exposure during the build compounds the mold and moisture risk

Lumber, subfloor, and insulation sit exposed to rain and humidity for weeks during framing. Materials that get wet and aren't properly dried before they're closed up behind drywall create the exact conditions for mold growth that can take years to show symptoms, and mold claims tied back to construction defects are some of the most expensive and contentious claims a builder can face.

Statutes of repose stretch the tail far beyond the warranty period

Most states give homeowners a legal window, often 6 to 10 years, called a statute of repose, to bring a construction defect claim after a home is completed, regardless of any warranty the builder offered. That means a builder's liability exposure on a single home doesn't end when the final walkthrough is signed; it can follow the business for the better part of a decade. A general liability policy that isn't built with that timeline in mind leaves that entire tail uncovered.

Completed Operations: The Coverage That Matters Most

General liability policies are split into two very different buckets of coverage: ongoing operations, which responds to injury or damage that happens while work is actively underway, and completed operations, which responds to injury or damage that happens after the work is finished, the job has been turned over, or the product has left the builder's control.

For most contractors, ongoing operations is where the bulk of claims activity happens: a tool falls, a trench collapses, a passerby gets hurt near the site. For a residential builder, it's the opposite. The overwhelming majority of serious claims, the foundation that cracks, the roof that leaks, the deck that collapses two years after the final inspection, the mold that's discovered when a new owner finally pulls up flooring, all fall under completed operations, because by definition they happen after the home has already been sold and occupied.

That makes completed operations, not ongoing operations, the coverage a residential builder actually depends on most. And it's also the coverage most likely to be quietly weakened in a policy without anyone noticing until a claim comes in and gets denied. Watch for these common ways completed operations gets restricted:

• A separate, often lower, aggregate limit for completed operations that can be exhausted by a single large claim, leaving nothing for the rest of the policy period
• Residential or habitational exclusions or limitations that some carriers attach specifically because they consider it a harder class, cutting off completed operations coverage for the exact work you do
• Mold, fungi, and bacteria exclusions that carve out one of the most common and expensive completed operations claims a builder will ever face
• Earth movement or subsidence exclusions that can gut coverage for foundation and settling claims, among the most common defect claims in new residential construction
• Subcontractor work exclusions that strip coverage for damage caused by subcontractors unless the builder can show proof of the subcontractor's own insurance at the time the work was performed

None of that is obvious from a declarations page or a one-page summary. It's written into the policy jacket itself, which is exactly why the next two sections matter as much as they do.

Occurrence vs. Claims-Made: Why This Choice Is Critical

This is, without question, the single most important structural decision in a residential builder's general liability policy, and it's one a lot of builders never think to ask about because most standard contractor GL is written on an occurrence form by default. It's worth understanding exactly why that matters, because not every policy, and not every layer of excess coverage sitting on top of it, follows that same rule.

Most standard commercial general liability forms for contractors are occurrence-based, and for a residential builder, that's the form you want to protect, not trade away for a lower premium on a claims-made alternative. The risk isn't hypothetical: builders change carriers to save money nearly every renewal cycle, and a claims-made policy with no tail coverage purchased means every prior year of completed work can be left with a gap the moment you switch. Before you ever sign a renewal, or move carriers, confirm in writing whether the general liability form, and any umbrella or excess layer stacked on top of it, is occurrence-based or claims-made, because they don't always match.

The Rest of the Stack: Workers' Comp, Auto, Excess & More

General liability is the foundation, but it was never meant to stand alone. A residential builder's full insurance program typically needs several other lines working alongside it:

General guidance only. The exact combination and limits a builder needs depend on project size, subcontractor structure, and state requirements.

Excess liability deserves special attention for residential builders specifically. Because habitational completed operations claims can involve a full home rebuild, extended temporary housing for a displaced family, and mold remediation all at once, it's not unusual for a single serious claim to exceed a $1 million primary GL limit. An umbrella or excess policy sitting on top of an occurrence-based primary GL, on a matching occurrence trigger, is what actually protects the business, and often the builder's personal assets, when that happens. Lenders, municipalities, and larger developments will also frequently require higher combined limits than a builder might otherwise carry on their own.

Why No Two GL Policies Are the Same

This is the part that catches even experienced builders off guard: two general liability policies from two different carriers, both labeled "$1,000,000 / $2,000,000 general liability," can respond completely differently to the exact same claim. The declarations page tells you the limits. It does not tell you the exclusions, conditions, and endorsements buried in the policy jacket, the full stack of forms actually attached to the policy, and that's where the real differences live.

Carriers build their general liability policies on a base form, then attach their own manuscript endorsements on top of it, which is why the same limit on paper can mean very different coverage in practice. For a residential builder, the exclusions and conditions worth checking, line by line, on every renewal and every new quote include:

• Residential, habitational, condo, or multi-family exclusions or sub-limits that some carriers attach specifically to steer away from the class
• Mold, fungi, and bacteria exclusions, and whether a buy-back or separate pollution policy is even available to fill that gap
• EIFS (exterior insulation and finish systems) exclusions, common in policies written for builders using synthetic stucco systems
• Earth movement, subsidence, and settling exclusions tied directly to foundation and grading defect claims
• Aggregate limits applied per policy vs. per project, which matters enormously if you're building several homes at once and one large claim shouldn't erode coverage for the others
• Subcontractor warranty and additional insured conditions that can void coverage for a subcontractor's work if you didn't collect the right certificate and hold-harmless agreement before they started
• XCU coverage (explosion, collapse, and underground property damage), which needs to be explicitly included, not assumed, for any builder doing excavation or foundation work

None of this means one carrier is "bad" and another is "good." It means the policy jacket, not the quote summary, is the actual contract, and it has to be read against the specific risk of building new residential homes, not treated as interchangeable with any other contractor's GL. This is exactly the kind of review an agent who understands habitational construction should be doing on every quote before you bind it, not after a claim gets denied.

Subcontractor Coverage & Certificates of Insurance

Because so much of a home's construction is performed by subcontractors rather than the builder's own crew, certificates of insurance are what actually connect a builder's completed operations exposure to the subcontractor who did the work. If a plumber's rough-in fails two years later and the plumber's own GL policy has since lapsed, or never existed, the claim can land squarely on the builder's policy instead, often stripped of the subcontractor exclusion buy-back if the right paperwork wasn't collected at the time.

A disciplined subcontractor program, current certificates on file for every trade before work begins, the builder listed as an additional insured, and a written hold-harmless or indemnification agreement, is one of the most effective ways to keep completed operations claims where they belong instead of concentrating all of it on the general contractor's own policy.
