A homeowner in Davis is three weeks into a whole-house remodel when a friend asks a simple question over coffee: did you call your insurance company first? The homeowner hasn't. The contract is signed, half the kitchen wall is open, and a dumpster has been sitting in the driveway since week one. Nobody thought to make that call, because nothing about signing a remodel contract feels like an insurance event.
It is one. The gap between what a standard California homeowners policy assumes about a house and what an active job site actually looks like is where most remodel insurance problems start, and it has almost nothing to do with builder's risk trivia. It's a standard policy quietly narrowing what it protects the moment a structure stops looking like a finished, occupied home.
We build houses in the Sacramento and Davis region. We don't sell insurance, and we're not your agent. This is a guide to the calls worth making before your project starts, built from what 20+ years of California construction work has taught us about where these gaps actually show up, 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 construction ballpark in about two minutes. It has no idea what your policy excludes, and neither should you assume it does. That's a separate conversation, and it belongs with your agent before demo day, not after a claim.
Your Homeowners Policy Was Never Written for a Job Site
A standard homeowners policy is priced and written around a specific picture: an intact, weathertight structure with a family living inside it. Every assumption baked into that policy, from how quickly water damage gets caught to how likely theft or vandalism is, depends on someone being home.
A remodel breaks that picture on purpose. Walls come down. A roof section disappears for a week. Contractors and subcontractors let themselves in and out all day. Materials and tools sit in the garage or the yard overnight. None of that means your policy stops working entirely, but several specific mechanisms inside a standard policy start to narrow the moment active construction begins, and most homeowners don't find out which ones until something goes wrong.
The three that matter most: the notice requirement for material changes to the property, the exclusions that separate a contractor's faulty work from an insured “ensuing loss,” and the vacancy clause. That last one is the biggest blind spot, and it's worth its own section.
Vacant vs. Unoccupied: The Distinction That Decides Your Coverage
This is the part almost nobody explains clearly, and it's the difference that actually decides what happens to your coverage during a remodel.
Industry guidance draws a real line between two words homeowners tend to use interchangeably. Unoccupied generally means nobody is living in the home day to day, but the furniture and personal belongings are still there. A lot of mid-remodel houses fit this description exactly: the family has moved into a rental in West Sacramento or a relative's place in Woodland while the crew works, but the couch, the beds, and the boxes are still sitting inside. Vacant generally means the home has also been stripped of that furniture and personal property. An empty shell with a general contractor's crew coming and going is a vacant structure under most policies, even if the family checks in every few days.
That distinction matters because most standard policies treat the two differently. An unoccupied home usually keeps something close to full coverage. A vacant home is what actually starts the clock on your policy's vacancy clause, and once that clock runs out, coverage for specific perils, commonly vandalism, theft, and water damage, gets limited or dropped entirely.
Here's the number homeowners usually don't know until it's too late: most policies set that clock at roughly 30 to 60 consecutive days, with 60 the more common default and some carriers using 30. That threshold isn't written into California law. It's written into your specific policy, and it varies by carrier, which is exactly why the only reliable answer is a phone call, not a guess.
Now apply that to an actual remodel timeline. A whole-house remodel or a second-story addition in this region commonly runs several months. If a family moves out and empties the house for that stretch, they can cross the 30- or 60-day vacancy threshold well before the project is anywhere near finished, and the standard fix, a vacancy endorsement, has to be arranged before that window closes, not after. Ask your agent about one the same week you sign a contract that requires moving out, not the week the crew starts framing.
The Exclusions That Activate Once Active Construction Starts
Short of full vacancy, a standard policy still narrows in ways that surprise people. A few worth knowing before you sign anything:
Faulty workmanship itself, meaning the actual quality of work a contractor performs, generally isn't something your homeowners policy covers at all. That risk sits with the contractor's own general liability coverage and the contract you signed with them, not your dwelling policy. Your policy is more likely to respond to an “ensuing loss,” damage that results from the faulty work, like water damage after a botched plumbing connection, than to the workmanship defect itself.
Materials and tools staged on site are a genuine gray area. Lumber, cabinets, and fixtures delivered ahead of installation, along with a contractor's own tools and equipment left in the garage overnight, often aren't covered by either the homeowner's policy or the contractor's standard liability policy unless someone has specifically arranged for it. This is one of the clearest reasons builder's risk exists as a separate product, covered below.
And a claim filed mid-construction gets read differently than one filed on a finished house. An adjuster reviewing a claim on an obviously open structure is going to ask what work was underway and when. None of this requires anyone to have lied. It just means the carrier was left out of a conversation they were entitled to be part of, and that changes how a claim gets handled.
Who Actually Carries What: You, Your Contractor, and the Gap Between
A remodel involves at least three separate layers of coverage, and knowing which one answers which question saves a lot of confusion later.
Your dwelling policy covers the structure itself against named perils, subject to everything above once construction narrows what it responds to.
Your contractor's general liability insurance covers damage the crew causes to your property or a neighbor's, and covers third-party injury claims that don't involve their own employees. This is what pays if a sub nicks a gas line or a delivery truck backs into a fence.
Your contractor's workers' compensation coverage covers an injured worker on your property, so that cost doesn't land on you as the homeowner. If a contractor has no workers' comp and someone gets hurt on your job site, that exposure can become yours.
Verifying which of these your contractor actually carries takes about two minutes at cslb.ca.gov, the Contractors State License Board's free license lookup. It shows license status, bond information, and workers' compensation status in one search. General liability is a separate check: California doesn't require a contractor to carry it to hold a license, so ask for an additional-insured certificate sent directly from the insurer or broker to your email, not a PDF the contractor forwards you, which can be outdated or edited.

When Builder's Risk Actually Fills the Gap
The layers above still leave a real hole: nothing described so far covers the work-in-progress itself, or materials staged on site, once a project moves past a contained scope. That's the specific job builder's risk insurance, also called Course of Construction coverage, is built to do.
It's a separate, temporary policy written for a structure that's actively under construction or renovation, generally covering the work in progress, materials on site, and often the existing structure while it's opened up. Either the homeowner or the contractor can be the one who buys it, so the contract should say plainly which of you is responsible. Assuming the other side has it arranged is exactly how this gap gets discovered mid-claim instead of before one.
National industry data commonly cites builder's risk premiums somewhere in the range of 1% to 5% of the total completed project value, with figures toward the higher end for remodels of older structures, since opening existing walls carries more uncertainty than building on a clean slab. Those are general planning figures from national insurance industry sources, not a quote for any specific policy or property, and no legitimate policy price gets set without underwriting your actual project.
Because a Course of Construction policy is written specifically for an unoccupied structure under active work, it generally doesn't carry the same 30- to 60-day vacancy clock a standard dwelling policy does. That's the direct answer to the vacancy problem above: on a project large enough to empty the house for months, builder's risk is often the actual fix, not an afterthought.
Where it tends to matter most in this region: room additions, detached ADUs, second-story additions, and whole-house remodels where the structure is substantially open or sits vacant for weeks. A contained kitchen or bathroom remodel in an otherwise occupied home is often adequately handled by the existing dwelling policy plus the contractor's insurance, without a separate builder's risk policy. Ask your agent directly whether your specific scope warrants it. Don't let a contractor tell you it's unnecessary; that's not their call to make, and it isn't ours either.
Want a real number for the construction itself before you price a builder's risk policy against it? SafewayQuickQuote.com estimates the build in about two minutes, no site visit required. It prices the project, not the insurance, so treat them as two separate conversations that both need to happen before you sign.
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 kitchen remodel or a new ADU raises what it would actually cost to rebuild your home. If your dwelling coverage limit doesn't move with it, you're underinsured starting the day the crew leaves, and the gap usually isn't discovered until a total loss forces a rebuild priced for a smaller, older house.
Call your agent once the project finishes and ask them to reassess your dwelling limit against the home's new replacement cost, including any added square footage from a room addition or ADU.
One statewide trend worth knowing about while you're at it. California's admitted home insurance market has tightened noticeably in recent years; the state's FAIR Plan, the insurer of last resort, saw enrollment grow roughly 43% between September 2024 and December 2025, with total exposure reaching an estimated $768 billion by June 2026, a 250% increase since September 2022. That growth is concentrated in wildfire-exposed foothill and wildland-urban-interface areas, and most of the Sacramento and Davis region sits in the valley rather than that terrain. But carrier appetite and renewal decisions shift statewide, not only inside mapped fire zones, so a non-renewal notice mid-remodel isn't purely a hillside problem anymore. If it happens to you, the California FAIR Plan covers a short list of named perils, fire, lightning, smoke, and explosion, and most FAIR Plan homeowners pair it with a Difference in Conditions, or DIC, policy for what it doesn't cover, like theft, liability, and water damage. Worth a conversation with your agent before you sign a contractor, not after a non-renewal letter shows up during framing.
ADUs: The Detached Structure Your Policy Probably Underprices
If you're adding a detached ADU in Sacramento, Elk Grove, Folsom, or anywhere else in the region, don't assume it's automatically wrapped into your existing coverage. Standard policies typically default coverage for detached structures, often labeled Other Structures or Coverage B, to around 10% of your main dwelling limit. A standard detached ADU in this region commonly runs $175,000 to $340,000 to build, a figure that's routinely far larger than 10% of a typical dwelling limit.
Get your agent involved before construction starts, not after the ADU is finished and rented out. Most insurers will let you raise Coverage B specifically for the new structure, or schedule it separately as its own endorsement. 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 Sacramento ADU guide and Davis ADU guide cover the construction and permit side; this is the coverage side that tends to get missed until after the ADU is already rented.
A Pre-Remodel Insurance Checklist
Work through this with your own agent before you sign a contract or schedule demo:
- Disclose the project scope, timeline, and whether the home stays occupied, unoccupied, or fully vacant during construction
- Ask specifically whether your project needs a builder's risk policy, and get in writing whether you or the contractor is buying it
- If the home will be emptied of furniture for the project, ask about a vacancy endorsement before the 30- or 60-day clock starts, not after
- Verify your contractor's license, bond, and workers' compensation status at cslb.ca.gov, and request an additional-insured general liability certificate sent directly from the insurer
- Plan to update your dwelling coverage limit once the project finishes, and set a specific, adequate limit for any new detached ADU
- Ask your agent how a non-renewal would be handled during an active remodel, and what the California FAIR Plan and a DIC policy would look like if it came to that

Frequently Asked Questions
Do I have to tell my insurance company before I remodel my house?
Yes, and it's worth doing before demo starts, 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 5% of the project's total completed value per national industry data, higher for remodels of older homes. Either the homeowner or the contractor can buy it, so the contract should say which.
What's the difference between a “vacant” home and an “unoccupied” home during a remodel, and why does it matter for my coverage?
Unoccupied generally means nobody's living there, but furniture and belongings remain. Vacant generally means the home is also stripped of personal property. Industry guidance treats these differently: an unoccupied home usually keeps closer to full coverage, while a vacant home is what actually triggers the policy's vacancy clause.
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, with 60 the more common default. The exact number is set by your specific policy, not state law.
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 do I check if my contractor has workers' comp and general liability insurance in California?
Check license, bond, and workers' comp status free at cslb.ca.gov. For general 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 or new ADU?
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% of your dwelling limit, often far less than a full ADU is worth. Set a specific limit with your agent before construction starts.
