Home Insurance During Renovations in California: Don't Get Caught Off

Home insurance during renovations in California: what changes and what doesn't

Home insurance during renovations in California is one of those topics most homeowners never think about until something goes wrong mid-project. You pull a permit, hire a contractor, and suddenly your house is partially open to the elements with strangers working in it every day. What you had covered before the first nail was driven may not fully protect you now. Understanding what shifts in your policy during a renovation, and what steps to take before work begins, can save you from a very expensive surprise.

Why standard homeowners policies get complicated during renovations

A standard homeowners policy is written to cover a home that is occupied, maintained, and in normal use. When a renovation starts, the risk profile of the property changes in several ways at once. Carriers underwrite based on the condition of the home at the time of the application, not the condition it will be in three months after a kitchen gut-out or a room addition.

The concerns that come up most often:

• Vacancy or reduced occupancy. Some large renovations force you to temporarily move out. Many standard policies contain a vacancy clause that suspends or limits coverage after 30 to 60 consecutive days of vacancy. If your Fresno home sits empty while a contractor rebuilds the master bath, you could unknowingly trigger that clause.
• Increased liability exposure. Workers, subcontractors, and material delivery people are on your property regularly. A slip-and-fall on your jobsite can become your problem if coverage lines are not clearly drawn.
• Theft of building materials. Copper wiring, appliances, and lumber staged at a job site are attractive targets. Standard policies often limit or exclude theft of materials that are not yet permanently installed.
• Fire and weather risk. An open roof deck or unfinished framing creates vulnerabilities that your carrier did not price into your premium. A Fresno Valley summer windstorm hitting an exposed structure is a different risk than one hitting a finished home.
• Increased dwelling value mid-build. If you are adding a room or a second story, the replacement cost of your home rises the moment construction begins. Your policy limit may be too low to cover a total loss partway through the project.

The coverage types that matter most when you're remodeling

Your existing homeowners policy

Start by reading the renovation and contractor language in your current policy. California homeowners policies issued by admitted carriers must follow Department of Insurance guidelines, but the specific language around under-construction properties, vacancy, and course of construction varies widely by carrier. Some carriers will add an endorsement to your existing policy to cover the renovation period. Others require a separate policy. A few will deny a mid-term claim outright if they were not notified of the project before work began. That notification requirement is often buried in the policy conditions section, and skipping it is one of the most common mistakes homeowners make.

Builders risk insurance

A builders risk policy is designed to cover a structure while it is under construction or renovation. For larger projects, adding this coverage is often the cleanest solution. It covers the structure, materials on site, and sometimes materials in transit against perils like fire, theft, vandalism, and certain weather events. Builders risk is typically written for a specific project term, often three, six, or twelve months, and it can be purchased by you as the homeowner or by the general contractor. Know who holds it before the project starts, because a gap here is where large losses fall through the cracks.

For context on how this product works, see the builders risk coverage page on the McCarty Insurance Agency site, which covers both residential and commercial project scenarios.

Personal liability coverage

Your standard homeowners policy includes personal liability, but it was not designed with an active construction site in mind. If a worker is injured on your property, the first question is whether their employer carries workers' compensation insurance. In California, contractors are required by law to carry workers' comp if they have employees. Unlicensed contractors and sole proprietors who do not carry it do exist, though. If a worker without coverage is injured on your property, you could face a lawsuit that tests the limits of your personal liability coverage quickly. Get certificates of insurance from every contractor before work starts, not after.

Dwelling coverage limits and increased reconstruction cost

California's insurance market has faced significant pricing pressure over the last several years, and reconstruction costs in the Central Valley have climbed with labor and materials. If you are adding square footage, a second story, or substantial upgrades, your current dwelling coverage limit may be outdated even before the renovation adds more value. An accurate picture of what your homeowners policy covers and at what replacement cost is a necessary starting point. Talk to your agent about whether your limit needs to be adjusted mid-policy or whether an endorsement for increased cost of construction makes sense.

Specific California considerations for renovation projects

California adds layers that homeowners in other states do not face. A few worth knowing:

• CSLB licensing requirements. The California Contractors State License Board (CSLB) requires contractors to be licensed for any project over $500 in labor and materials combined. Using an unlicensed contractor voids certain consumer protections and complicates insurance claims significantly. Always verify a contractor's CSLB license number before signing a contract.
• Earthquake exposure during construction. California's seismic risk does not pause for your renovation. A structure in progress, especially one with walls open or foundation work underway, is more vulnerable to earthquake damage than a finished home. Standard homeowners policies do not cover earthquake damage. If you carry a separate earthquake policy, review whether it extends to a structure under renovation or whether the in-progress condition affects a claim.
• Wildfire risk in Fresno County and surrounding areas. If your project is in or near a wildland-urban interface area (think Shaver Lake, Friant, or the foothills east of Clovis), construction activity creates additional fire ignition points. Grinding, welding, and temporary electrical setups are common causes of construction fires. Let your carrier know if the project is in a higher-risk fire zone.
• Building permits and policy compliance. Pulling the proper permits is not just a code requirement. It also matters to your insurer. If a fire or structural failure occurs in an unpermitted addition, your carrier has grounds to deny or reduce the claim on the basis that the work was not done to code. Cutting corners here costs far more than the permit fee.
• California's insurance availability situation. Several large carriers have reduced or halted new homeowner policy issuance in California. If your renovation significantly changes the risk profile of your home, you could find yourself in a situation where your carrier nonrenews the policy and replacement coverage is harder to find. Understanding the current state of California's homeowners insurance market before starting a major project is worth the time it takes to get up to speed.

Steps to take before your contractor breaks ground

Getting this right requires a few specific actions before work starts rather than after a loss occurs.

• Call your insurance agent. This is the first call, not the last one. Describe the scope of work, estimated project value, whether you will remain in the home during construction, and the expected timeline. Your agent can identify gaps in your current coverage and recommend whether a builders risk policy, a policy endorsement, or a temporary coverage change is the right fit.
• Collect certificates of insurance from every contractor. You want to see general liability and workers' compensation certificates, with your name listed as an additional insured on the liability policy. This shifts the exposure back to the contractor's coverage if their work causes damage or injury.
• Update your dwelling coverage limit. Get a current replacement cost estimate, particularly if the project will add square footage or substantially upgrade finishes. Reconstruction costs in California's Central Valley have increased substantially in recent years, and being underinsured at the time of a loss means paying the gap yourself.
• Understand your policy's vacancy clause. If the renovation requires you to move out temporarily, find out exactly how many days trigger the vacancy provision in your policy and what it does to your coverage. Ask your agent to put the answer in writing.
• Document everything. Photograph the existing condition of the home before work begins. Keep contracts, permits, and payment records organized. If a dispute arises with your carrier over the cause or scope of a claim, good documentation is your best asset.

What happens if something goes wrong mid-renovation without the right coverage

Consider a realistic scenario. A homeowner in Clovis starts a significant kitchen expansion. The contractor frames out the new addition, and a portion of the original roof is temporarily removed to connect the structures. A late-season rain event hits harder than expected. Water intrudes and damages the original structure's flooring, cabinetry, and drywall. The homeowner files a claim with their standard homeowners carrier. The carrier investigates and determines the damage occurred because the roof was intentionally removed as part of an ongoing construction project. The claim is denied on the basis that the loss arose from the renovation, which was not disclosed to the carrier and is excluded under the policy's course-of-construction exclusion.

That scenario is not hypothetical. It plays out regularly. A builders risk policy or a properly endorsed homeowners policy would have covered the water intrusion. The cost of that additional coverage for a six-month project would have been a fraction of the claim denial.

A separate example: a homeowner hires a handyman who is not licensed and does not carry workers' comp in order to save money on tile work. The handyman falls off a ladder, breaks a wrist, and files a civil suit. The homeowners liability coverage responds, but the limits are $100,000. The medical bills, lost wages, and legal fees exceed that amount, and the homeowner is personally responsible for the difference. A personal umbrella policy would have provided additional protection above the base liability limit. This is one reason a personal umbrella policy is worth discussing any time you are taking on a project that brings other people onto your property regularly.
