Here's how it usually goes. A homeowner in Thousand Oaks signs a remodel contract, picks a start date, and spends two weeks choosing tile and cabinet hardware. Demo day arrives. Nobody called the insurance carrier. It doesn't come up again until something goes wrong, a burst supply line, a tool theft off the job site, a wind event through an open roof, and that's the worst moment to find out what your policy actually covers.
We build houses. We don't sell insurance, and we're not your agent. But after 20+ years remodeling homes across Simi Valley, Camarillo, Moorpark, and Oxnard, we've seen enough claims conversations happen mid-project to know where the gaps usually are. This is a guide to the calls worth making before your project starts, not legal or tax advice, and not a substitute for your own agent or broker. If you haven't priced your project yet, SafewayQuickQuote.com gives you a ballpark in about two minutes. It answers what your remodel will cost, not whether you're covered if something happens during it, and that's a separate conversation worth having early.
Call Your Carrier Before Demo, Not After
Most homeowners policies require you to tell your carrier about material changes to the property. A remodel that opens up walls, removes part of a roof, or leaves rooms unoccupied for stretches of time qualifies, even though nothing about your policy technically stops you from starting work without that call.
Here's what changes if you skip it. If a claim comes in during construction, an adjuster is going to ask what work was underway and when. “A full kitchen gut, three weeks in, and we hadn't mentioned it” gives the carrier grounds to dispute the claim, delay payment, or argue the loss happened under conditions the policy wasn't written for. None of that requires anyone to have lied. It just requires the carrier to have been left out of a conversation they were entitled to be part of.
The call itself usually takes ten minutes. Tell your agent the scope, the rough timeline, and whether the home stays occupied. Most of the time they'll confirm your existing policy is fine as-is and note the project on file. Occasionally they'll flag something, and that's the answer you want before demo, not during a claim. If you want help describing the scope accurately, call us at (805) 222-6544 and we'll walk you through what the project actually involves.
Dwelling Policy vs. Builder's Risk: Which One Actually Covers Your Project
A standard homeowners policy is built around a finished, occupied house. It assumes an intact roof, closed walls, and a family living inside. A remodel breaks every one of those assumptions for weeks or months at a time.
Builder's risk insurance, sometimes called Course of Construction coverage, is a separate, temporary policy written specifically for a structure under construction. It typically covers work in progress, materials staged on site, and often the existing structure while it's opened up, things a standard dwelling policy wasn't built to anticipate. Either the homeowner or the contractor can be the one who buys it, and the contract should say plainly which of you is responsible, because assuming the other side has it is how a gap gets discovered mid-claim. Builder's risk commonly runs 1 to 4 percent of total project value, and remodels of older structures tend toward the higher end, 2 to 4 percent, because opening existing walls carries more uncertainty than building on a clean slab.
For a contained kitchen or bathroom remodel where the rest of the house stays occupied and largely intact, your existing dwelling policy combined with your contractor's insurance is often enough. Builder's risk becomes worth a real conversation for larger scopes: room additions, ADUs, second-story additions, or a whole-house remodel where the structure is substantially open or the home sits unoccupied for weeks. On a $250,000 whole-house project, that 1 to 4 percent range works out to $2,500 to $10,000, a real cost, but a small one against an uninsured loss mid-construction. It also matters for the vacancy clause below: a Course of Construction policy generally doesn't carry the same 30- to 60-day vacancy limit a standard dwelling policy does, since it's already written for an unoccupied, in-progress structure.
Ask your agent directly whether your project's scope warrants it, and get it in writing whether you or we're the one buying it. Don't let a contractor tell you it's unnecessary. That's not their call, and it's not ours either.
The Vacancy Clause Trap: What Happens If You Move Out
This is the gap that catches Ventura County homeowners doing whole-house remodels or second-story additions off guard. Move out while the work happens, into a rental in Newbury Park or a relative's place in Moorpark, and your standard policy's protection can start eroding the moment the house sits empty.
Most standard homeowners policies include a vacancy clause that limits or drops coverage for specific perils, commonly vandalism, theft, and water damage, once a home has sat vacant for roughly 30 to 60 consecutive days. That threshold isn't state law; it's written into your specific policy and varies by carrier. “Vacant” usually means stripped of furniture, which describes a lot of mid-remodel houses exactly.
If your timeline runs past that window, ask your agent about a vacancy endorsement before you move out, not after the 30- or 60-day mark passes quietly during framing. It's far cheaper to arrange in advance than to discover you don't have it after a loss.
Verify Your Contractor's Coverage, Not Just Their Estimate
A contractor's insurance protects you, not just them. If a worker gets hurt on your Camarillo or Simi Valley property and the contractor has no workers' comp, that cost exposure can land on you. If a sub nicks a gas line or damages a neighbor's fence, general liability is what pays for it instead of your own policy.
Two things to check before you sign anything. First, general liability and workers' comp, verified free at the Contractors State License Board's license lookup , which shows license status, bond, and workers' comp coverage in about two minutes. Second, an additional-insured certificate sent directly from the insurer, not a PDF the contractor emails you. A forwarded PDF can be outdated or edited; a certificate issued straight from the carrier confirms the policy is active as of the day you asked.

Update Your Dwelling Limit After the Project Wraps
This is the step homeowners forget most, because it happens after the excitement of the project is over. A $120,000 kitchen remodel or a new ADU raises what it would actually cost to rebuild your home. If your dwelling limit doesn't move with it, you're underinsured starting the day the crew leaves, and you won't find out until a total loss forces you to rebuild with a limit set for a smaller, older house.
Call your agent once the project wraps and ask them to reassess your dwelling limit against the home's new replacement cost, including any new square footage from an addition or ADU.
The Ventura County Wildfire Wrinkle
This piece is specific to where we build. Parts of Ventura County, including hillside areas of Simi Valley, Thousand Oaks, Newbury Park, Agoura Hills, and Oak Park, sit inside CAL FIRE-mapped high or very high fire hazard severity zones, and carriers have been non-renewing policies and restricting new coverage across these zones statewide.
A mid-remodel non-renewal is worse than one on a finished house. An open structure is harder for a new carrier to underwrite or appraise, and often gets a flat decline rather than a quote while construction is visibly incomplete. Loop your agent in early if you're in a high-fire-severity zone, before you sign a contractor, not after a non-renewal notice arrives during framing.
If your existing carrier drops you, the California FAIR Plan is the state-mandated fallback, covering a short list of named perils: fire, lightning, smoke, and internal explosion. It's not a full homeowners policy, which is why most FAIR Plan homeowners pair it with a Difference in Conditions (DIC) policy that wraps around it to cover theft, liability, and water damage the FAIR Plan doesn't touch. Combined premiums in very high fire hazard zones can run well above what a standard policy would have cost, so this is worth a conversation with your own broker well before demo.
Our wildfire home hardening guide covers fire-resistant upgrades worth building in while the walls are already open, which can factor into how a carrier views the finished home.
ADUs: A Detached Structure Usually Isn't Automatically Covered
If you're adding a detached ADU, don't assume it's automatically wrapped into your existing coverage. Standard policies typically cap detached structures, often labeled Other Structures or Coverage B, at around 10 percent of your main dwelling limit. A full one- or two-bedroom ADU is usually worth far more than that.
Get your agent involved before construction starts, not after the ADU is finished and rented out. If you're planning to rent it, ask about a landlord or rental-property endorsement too, since a tenant-occupied structure carries different liability exposure than one used by family. Our Ventura County ADU cost guide covers construction pricing.
A Pre-Remodel Insurance Checklist
Before you sign a contract or schedule demo, work through this with your own agent:
- Disclose the project scope, timeline, and whether the home stays occupied
- Ask whether your project warrants a builder's risk policy, especially for additions, ADUs, or whole-house scopes
- If you're moving out during construction, ask about a vacancy endorsement before the 30- to 60-day clock starts
- Verify your contractor's license, bond, and workers' comp status at cslb.ca.gov, and request an additional-insured certificate sent directly from the insurer
- If you're in a high fire hazard severity zone, ask about renewal risk before you start
- Plan to update your dwelling coverage limit once the project finishes, and set a specific limit for any new ADU

Frequently Asked Questions
Do I have to tell my insurance company before I remodel my house?
Yes, and it's worth doing before demo, not after. Most policies require notice of material changes, and skipping it gives a carrier grounds to dispute a claim if something happens mid-project and they later learn work was underway without notice.
What's the difference between homeowners insurance and builder's risk insurance?
A standard policy is built for a finished, occupied house. Builder's risk, also called Course of Construction coverage, is a temporary policy for a structure under construction, commonly costing 1 to 4 percent of the project value, higher for remodels of older homes. Either the homeowner or the contractor can buy it, so the contract should say which.
Do I need builder's risk insurance for a kitchen or bathroom remodel?
Not always. Contained remodels in an occupied home are often covered by your existing policy plus your contractor's insurance. Larger scopes, additions, ADUs, and whole-house remodels warrant a direct conversation with your agent.
How long can my house sit vacant during a remodel before I lose coverage?
Most policies limit coverage for things like vandalism and theft after roughly 30 to 60 consecutive vacant days. The exact number is set by your specific policy, not state law.
How do I check if my contractor has workers' comp and liability insurance?
Check license, bond, and workers' comp status free at cslb.ca.gov. For liability, request an additional-insured certificate sent directly from the insurer, not a PDF forwarded by the contractor.
Do I need to increase my homeowners insurance after a remodel?
Usually yes. A kitchen remodel or new ADU raises your home's replacement cost, and an unchanged dwelling limit means underinsurance at claim time.
Is a detached ADU automatically covered by my homeowners policy?
No. Coverage for detached structures is typically capped around 10 percent of your dwelling limit, often far less than a full ADU is worth. Set a specific limit with your agent before construction starts.
What happens if my insurance company won't renew my policy during a wildfire zone remodel?
It's a real risk in Ventura County's high fire hazard severity zones. The California FAIR Plan is the state-mandated fallback, typically paired with a Difference in Conditions policy to cover what the FAIR Plan alone doesn't.
