Most homeowners assume their existing policy covers whatever happens during a renovation. That assumption holds up fine when you’re repainting a bedroom. It gets shaky when you’re adding a second story.
The distinction matters because major renovations — additions, gut kitchens, full basement finishes, accessory dwelling units — change what your home is in the middle of the process. Carriers underwrite the finished, occupied structure you described when you applied. They didn’t price a partially framed addition exposed to weather, a skeleton of a house with the plumbing stripped out, or a structure with half a dozen subcontractors cycling through it daily.
What Standard Homeowners Policies Typically Exclude During Construction
A standard homeowners policy is written around a few baseline assumptions: you live there, it’s structurally complete, and you’re the one managing the premises. Major renovation breaks every one of those assumptions.
The coverage gaps most often surface in two areas.
First, the dwelling coverage itself. Many policies contain vacancy or construction clauses that limit or suspend coverage once a home crosses a threshold of incompleteness — particularly if you’ve moved out for the duration. The exact trigger language varies by carrier, but the general principle is consistent: if the home isn’t being used as a residence and is actively under construction, the carrier may not respond the way you’d expect to a fire, a burst pipe, or a windstorm that takes the framing down.
Second, the materials and equipment sitting on-site before they’re installed. Your cabinets stacked in the garage, the hardwood flooring piled in the living room, the HVAC unit staged in the driveway — those may not be covered under your existing policy. They’re not yet part of the dwelling, and they’re not quite personal property in the traditional sense. In our experience, this is where homeowners are most surprised after a loss: they assumed the contents coverage would protect materials, and found out it didn’t.
Builder’s Risk: What It Actually Covers
Builder’s risk insurance is a property policy written specifically for the structure during construction or renovation. It covers the building in progress, materials on-site, and in many forms, materials in transit to the site. When a fire destroys a half-completed addition or a break-in takes copper fixtures before they’re installed, a builder’s risk policy is what pays.
Builder’s risk works differently depending on who purchases it — the homeowner, the general contractor, or both. This is worth examining before any work begins, because gaps are common. A general contractor’s policy typically covers their interest in the project and may extend to the structure they’re building, but it doesn’t necessarily cover your existing home, and it certainly isn’t written to cover your personal belongings inside it.
For major renovations where the homeowner is staying in the home during construction — common in Bethesda splits and McLean colonials where owners add to one wing while living in the other — the question becomes whether you need a builder’s risk policy layered on top of your existing homeowners coverage, or whether your carrier will endorse the existing policy to account for the construction activity. Both approaches exist; which one applies depends heavily on the scope of work and your current carrier.
If you’ve moved out entirely — say, you’re doing a full gut renovation of a Capitol Hill rowhouse and renting elsewhere for six months — the vacancy dimension adds another layer. Vacant homes are harder to insure and more expensive when you can, because they attract more claims: fires that go undetected, pipes that burst with no one home to notice, and break-ins that go unreported for days.
The Liability Piece Most People Miss
When your home becomes a job site, the liability exposure changes materially.
Your homeowners liability coverage is written around you and the premises as a residence. Contractors and their employees are typically excluded from the standard personal liability coverage when they’re injured on the job — that’s what workers’ compensation insurance is for, and your general contractor should be carrying it. But “should be” is doing a lot of work in that sentence.
In the DC metro, we regularly see renovation projects staffed with a mix of licensed GCs, unlicensed subcontractors, and day labor. The workers’ comp coverage chain breaks at different points depending on licensing and employment classification. If a subcontractor who lacks workers’ comp coverage is injured on your property, the question of who’s liable — and who pays — can pull in your homeowners policy in ways you didn’t anticipate.
This is a conversation worth having before you sign the construction contract, not after someone is hurt. At minimum, ask your contractor for their certificate of insurance, verify it’s current, and confirm that subcontractors are also covered. We help clients think through what to look for in those certificates, because a certificate that’s technically valid can still leave gaps.
What the Contractor’s Insurance Covers — and What It Doesn’t Cover for You
Contractor general liability coverage protects the contractor’s business from claims arising out of their work. It is not — and we want to be direct here — a substitute for your own coverage as the homeowner.
Consider a scenario that comes up more often than people expect: a renovation triggers a water loss that damages neighboring property. The contractor’s liability policy may cover the claim against the contractor. But what about the delay, the disruption to your project, and the incidental damage to your belongings? That falls into a different set of conversations entirely, and the default answer is often “not the contractor’s policy.”
Similarly, if there’s a dispute about defective work — materials installed incorrectly, a roof that leaks after the job is supposedly done — that’s often a construction defect claim, not a covered property loss. Homeowners sometimes assume their policy will step in while they’re fighting with the contractor over responsibility. It usually won’t, and the contractor’s liability policy may specifically exclude faulty workmanship from the coverage it extends.
Renovation Scale and the Valuation Problem
Here’s a practical issue that’s easy to overlook: major renovations change what it costs to rebuild your home. If you’re adding a thousand square feet, or converting a basement into finished living space, or doing a high-end kitchen with custom everything — your dwelling coverage limit needs to reflect the home after the work, not before.
We’ve placed homeowners coverage on properties where the owners did significant work over several years and never updated the dwelling limit. After a total loss, they found themselves underinsured by a meaningful margin, because the cost to rebuild had grown while the coverage number stayed static.
The right time to revisit your dwelling coverage limit is before the renovation begins — because you can document the pre-renovation state clearly — and again when the work is complete. If you’re using a homeowners policy through us, we build this into the renewal process, but if coverage has been sitting untouched elsewhere for years, it’s worth a look.
Practical Steps Before Your Contractor Shows Up
We’re not going to frame this as a checklist, because it isn’t really a checklist problem — it’s a judgment call at several points during planning. But a few conversations tend to be most useful.
Talk to your insurance agent before permits are pulled. The scope of work, the expected duration, whether you’re staying in the home, and the value of materials being staged on-site all affect what coverage looks like. Some carriers want to know about major work in advance; others include construction activity under endorsement without a separate notification process. You don’t want to find out which camp your carrier is in after a loss.
Verify the contractor’s insurance — and verify it yourself, not through a certificate mailed directly from the contractor’s broker. Certificates of insurance can be outdated; calling the issuing agency to confirm the policy is active takes about five minutes and is worth it on a job of any size.
Understand the project’s effect on your liability profile. If this is a large project with multiple subcontractors, the liability exposure during construction is different from the exposure of a quiet finished home in Great Falls or Vienna. Your umbrella policy may need to account for this period specifically — and not all umbrella carriers treat renovation work the same way.
What We’re Watching
The renovation market in the DC metro has stayed active, and the trend toward accessory dwelling units, in-law suites, and major additions hasn’t slowed much despite broader housing market uncertainty. As construction costs have risen, the gap between what standard homeowners policies cover and what it actually costs to rebuild a partially constructed project has widened.
We’re also watching how carriers handle the increasingly blurry line between renovation and new construction — particularly on teardown-and-rebuild projects in neighborhoods like Chevy Chase, Potomac, and McLean where older homes are being replaced with custom builds. That scenario sits differently in underwriting than a standard renovation, and the coverage structure reflects it.
If you’re planning a major project and want to think through where your current coverage stands — or doesn’t — that’s exactly the kind of conversation we have before permits, not after losses. Reach us at 301.468.9600 or info@capitalpointins.com.
