Sometimes, standard homeowners insurance may cover small remodels, but larger or structural projects usually need a builders risk policy or a specific endorsement. Before any work starts, notify your insurer in writing and confirm your contractor carries liability and workers’ compensation coverage. Those two steps determine whether a loss during construction gets paid or denied.
TL;DR:
- Builders risk insurance is necessary for structural changes, large additions, or projects above your insurer’s notification threshold, not just cosmetic renovations.
- Verifying your contractor’s liability and workers’ compensation coverage in writing before work starts is crucial for claim approval and risk management.
- Standard homeowners policies cover small remodels and materials on site if endorsed but exclude faulty work, defects, and long-term wear or latent issues.
- Renovation insurance must be tailored to the project’s scope, with contractor or homeowner purchasing policies to ensure proper coverage during construction.
- Updating your coverage and limits after remodeling ensures you reflect the new rebuild costs, especially when adding high-value fixtures or expanding the home.

What renovation insurance is and how it differs from homeowners coverage
A dwelling under renovation endorsement extends your existing homeowners policy to reflect the fact that your house is a construction site, not just a lived-in home. Builders risk, also called course of construction insurance, is a separate policy built specifically for a property mid-renovation.
- A renovation endorsement typically keeps your existing structure and liability coverage active while work is underway.
- Builders risk covers the work in progress itself, plus materials and supplies on site or in transit.
- Builders risk exists because a half-finished house has a value that changes week to week, something a standard policy was never designed to track.
The AAA/ACG guidance on renovations notes that for major structural work, homeowners should ask about builders risk before the first hammer swings, since it is built to cover physical loss to the work itself, not just the existing house around it.
What is commonly covered during renovations
For smaller projects, homeowners insurance often continues protecting the existing structure against the same perils it always has: fire, windstorm, theft, and vandalism. When a policy includes a renovation endorsement, that protection can extend to materials waiting to be installed.
- Fire, storm, and vandalism damage to the existing structure during a covered renovation.
- Materials or fixtures on site, when the policy specifically endorses coverage for them.
- Tools and equipment left at the property, subject to policy limits and exclusions.
Additional living expense (ALE) coverage applies if a covered loss makes the home unlivable, according to Liberty Mutual’s ALE guidance, though it comes with dollar and time caps and generally does not apply if you simply chose to move out for a remodel. That distinction trips up a lot of homeowners who assume any disruption qualifies.
Liberty Mutual’s remodeling coverage page points out that common gaps include theft of uninstalled materials and injuries to workers or visitors, gaps a renovation endorsement or builders risk policy is meant to close.
What renovation insurance typically does not pay for
Insurance is not a warranty. It pays for sudden, accidental loss, not for the planned cost of your project or a contractor’s mistakes.
- Faulty workmanship, bad design, and defective materials are generally excluded, according to the III’s HO-3 sample policy language, which specifically excludes faulty planning, specifications, and construction.
- Gradual wear and tear and latent defects that existed before the loss are not covered.
- Flood and earthquake damage require separate policies in most cases.
- Extended vacancy, commonly 30 to 60 days depending on the policy, can suspend coverage entirely if the home sits empty during a long renovation.
Code-related costs are a related trap. If your remodel triggers permit requirements you did not budget for, that expense falls on you, not your insurer. Our guide to bathroom remodel permits walks through what usually needs sign-off.
When to buy builders risk insurance
A homeowners endorsement is fine for a cosmetic refresh. Builders risk becomes the right tool once the project changes the bones of the house.
- Foundation or structural work. Anything touching load-bearing walls, footings, or the roof structure pushes you past endorsement territory.
- Additions that change the building’s footprint. New square footage means new exposure the existing policy was never priced for.
- Projects above your insurer’s notification threshold. Some insurers set a dollar figure past which they require a separate policy; ask directly rather than assuming.
Builders risk can be written on a completed value basis, where the policy pays a percentage of the finished value matching how much was done at the time of loss, or on a reported value basis, where you report progress periodically. The AAA/ACG explainer on renovations breaks down both structures. Terms usually run for the length of the project, with extensions available if work runs long.
Either the homeowner or the contractor can purchase the policy. Owner-purchased policies give you direct control over claims; contractor-purchased ones can simplify billing but leave you dependent on someone else’s paperwork.
Pro Tip: Ask who is named as the policyholder on any contractor-purchased builders risk policy. If it is not you, get written confirmation of your rights as an interested party before signing anything.
Notify your insurer and verify contractor insurance before work begins
This is the step that determines whether a claim gets paid. Two conversations, done in writing, protect you far more than any brochure.
- Tell your insurer the project scope, estimated value, timeline, and whether the home will be vacant at any point, then ask for written confirmation of coverage.
- Request your contractor’s general liability certificate and workers’ compensation proof, including policy numbers.
- Ask who insures subcontractors and confirm it directly, since a contractor’s word is not the same as verified coverage.
- Clarify who owns materials once delivered but before installation, a detail that affects who files a claim if something goes missing.
The NAIC’s contractor scam prevention guidance recommends calling the insurer listed on any certificate to confirm the policy is active rather than trusting a photocopy. Our breakdown of construction contract types covers how material ownership is typically assigned in a written agreement.
Pro Tip: Keep a folder, physical or digital, with every certificate, confirmation email, and policy number. Insurers ask for this exact paperwork when a claim is filed.
Update your coverage, limits, and liability after the renovation
Once the work wraps, your old policy numbers are probably outdated. A kitchen expansion or added bedroom changes what it would cost to rebuild the house from scratch.
- Reassess your dwelling limit using reconstruction cost, not market value, since the two rarely match.
- Consider an inflation guard or extended replacement cost endorsement if the renovation pushed your rebuild cost higher than your current limit.
- Update personal property limits to reflect new appliances and fixtures, and schedule anything especially high-value.
- Review liability limits if you added a pool, deck, or other feature that increases visitor risk, and consider an umbrella or excess policy.
The NAIC’s consumer guide to home insurance and III’s homeowners insurance handbook both stress reconstruction cost over market value, since renovations typically raise what it takes to rebuild, not necessarily what the home would sell for.
A practical checklist: before, during, and after the work
- Before: Document the project’s scope and estimated value, notify your insurer in writing, verify contractor liability and workers’ comp, and secure permits and a signed contract.
- During: Photograph progress regularly, secure materials on site, keep every receipt, verify subcontractor certificates as they show up, and report any incident to your insurer right away.
- After: Get a completion statement from your contractor, request an insurer reassessment of your dwelling limit, and schedule any new high-value items.
The NAIC’s contractor verification guidance recommends keeping printed or screenshotted proof of every insurer confirmation call in your project file, since verbal confirmations alone are hard to prove later if a dispute comes up.
A builder’s view on coordinating insurance through a remodel
Contractors who document scope carefully make the insurance conversation easier for everyone. A detailed set of plans, staged photos, and clear milestone updates give an insurer exactly what it needs to confirm coverage without back and forth. Tools like virtual consultations and 3D renderings can double as a paper trail that supports both the homeowner’s insurer notification and any claim that comes later.
Homeowners should expect that living arrangements, protected finishes, and project timelines all interact with policy terms, not just the contract price. Our own guidance on living through a renovation covers the practical side of staying in or near a construction zone, and it pairs well with whatever your insurer asks you to confirm in writing.

Planning a remodel that needs the right coverage in place
Getting the insurance conversation right matters just as much as getting the design right, and that is where working with a builder who documents everything pays off. Some builders coordinate kitchen and bathroom remodels, room additions, and ADU builds with a single point of contact managing both design and construction to help ensure communication between insurer and contractor.
If you are weighing a kitchen remodel, the kitchen remodeling page outlines project ranges from small updates to luxury overhauls. Homeowners planning an addition or considering an ADU can review the room additions or ADU build service pages for scope details relevant to an insurer conversation. Reach out through Prestigioushome to talk through your project before you call your insurance agent, so you walk into that conversation with real numbers instead of guesses.

Start with your insurer’s own policy wording, the NAIC’s contractor verification guidance, and the III’s sample HO-3 language. Rules vary by insurer and jurisdiction, so treat these as a starting point, not a final answer. For readers outside the United States, renovation insurance guidance from New Zealand and a UK-focused explainer on arranging cover before work starts show how these same principles play out under different rules.

FAQ
Can I use home insurance to renovate my house?
Home insurance does not pay for planned renovation costs. It may continue covering the existing structure against perils like fire or storm during a minor remodel, but you need a separate builders risk policy or endorsement for larger structural work, according to Liberty Mutual’s remodeling guidance.
What is the 30% rule for renovations?
There is no universal insurance rule set at 30%, and that figure is not defined in current insurer or NAIC guidance. If you have heard this framing, treat it with caution and confirm any threshold directly with your own policy documents rather than assuming a standard percentage applies.
What insurance do I need when renovating?
At minimum, notify your homeowners insurer in writing and confirm whether a renovation endorsement covers your project, or whether you need a separate builders risk policy for structural work. You should also verify your contractor’s general liability and workers’ compensation coverage directly with their insurer, as recommended by the NAIC.
How much does contractor insurance cost?
Pricing for contractor liability coverage varies by project value, location, construction type, and insurer underwriting, and no single published figure applies universally. Compare quotes using identical coverage limits and definitions, and get the terms in writing before work begins.
