Ontario Warehouse Fire (Kimberly-Clark): Maximize Your Insurance Claim

By now, you’ve probably seen the footage. A 1.2-million-square-foot Kimberly-Clark distribution center (roughly the size of 11 city blocks) in Ontario, California, engulfed in flames. Thick black smoke rolling across the Inland Empire for hours. 175 firefighters from agencies across Southern California working through the night and into the next day to get the blaze under control.

The fire broke out just after 12:30 a.m. on April 7 near Hellman and Merrill avenues. The warehouse, operated by third-party logistics company NFI Industries, was packed with paper products. Toilet paper, tissues, diapers. All of it highly flammable, and all of it gone. The roof collapsed entirely. Fire officials confirmed that everything inside was destroyed.

Authorities have already arrested a suspect on possible felony arson charges as they investigate further. About 20 employees evacuated safely, though many, like forklift driver Alejandro Montero, are now waiting to hear whether they’ll be relocated to other NFI facilities.

The fire left dozens of workers without a workplace overnight, and the uncertainty for those families is real. NFI Industries says they’re working to relocate affected employees, and San Bernardino County has directed anyone needing assistance to the West Valley America’s Job Center in Rancho Cucamonga at (909) 941-6500.

For the businesses and property owners in the surrounding area, a different challenge is unfolding: navigating the insurance claims process for smoke damage, lost revenue, and disrupted operations. If that’s you, this article is for you.

You Don’t Have to Have Been Inside the Warehouse to Have a Claim

This is the part that catches a lot of people off guard. When a fire burns through more than a million square feet of paper products for 12-plus hours, the impact zone stretches well beyond the property line. We’ve seen it time and again with large commercial fires across California. The neighboring businesses and properties often suffer losses that are just as real, just as costly, and just as covered under their insurance policies.

So what does that actually look like in a situation like this?

Consideration 1: Smoke Infiltration

Smoke from a fire this size doesn’t just blow away. It gets pulled into HVAC systems. It settles into wall cavities, ceiling tiles, upholstery, carpeting, and stored belongings. Whether you run a business with inventory on shelves or you’re a homeowner who noticed a lingering smell in your living room a few days later, the damage is real. Professional smoke remediation is expensive, and it’s almost always underestimated in early insurance assessments.

Consideration 2: Ash and Particulate Fallout

If your business has exposed inventory, rooftop equipment, or fresh air intake systems, the ash may have already done damage you haven’t fully accounted for. For homeowners, think patio furniture, vehicles, outdoor play equipment, pool systems, and exterior surfaces. CBS LA reported black smoke covering the area with ash landing in nearby yards.

Consideration 3: Water and Chemical Runoff

Thirty-five fire engines pumping water onto a building that size for over half a day means an enormous volume of contaminated water flowing into the surrounding area. For commercial properties, that could mean damage to parking surfaces, loading docks, and drainage infrastructure. For homes, think foundations, landscaping, driveways, and garages.

Consideration 4: Business Interruptions and Displacement

If you lost revenue because roads were closed, customers stayed away, or air quality advisories forced you to shut down, that’s potentially covered under business interruption provisions in your commercial policy. Homeowners who were unable to stay in their residence or incurred extra expenses due to the fire’s impact should look into additional living expense coverage under their homeowners policy.

Why the First Offer Is Rarely the Full Story

Insurance companies move fast after major events. That speed can feel reassuring, but the adjuster who shows up works for the insurer, not for you.

The data backs this up. In California specifically, Insurance Commissioner Ricardo Lara took legal action against the state’s FAIR Plan in 2025 for systematically denying smoke damage claims from wildfire survivors, uncovering at least 418 violations of California’s consumer protection laws. The Department also issued Bulletin 2025-7 directing all insurers to properly investigate and pay legitimate smoke damage claims. Smoke damage denial is not a theoretical risk in this state. It’s a documented pattern that California’s own regulators have had to intervene on.

Because this fire was ruled an arson, insurance companies may also take longer to investigate. That shouldn’t affect the validity of your claim (the criminal actions of someone else doesn’t change what’s in your policy), but it can introduce delays that make professional representation even more important from the start.

Five Steps You Should Take Right Now

The actions you take in the next few days and weeks will shape the outcome of your claim more than almost anything else. Here’s a clear path forward.

1. Document everything immediately

Walk through your property and capture every sign of damage on camera, no matter how minor it seems. For businesses, that means the exterior, interior, equipment, inventory, HVAC vents, and parking areas. For homeowners, walk room by room and photograph walls, ceilings, carpets, furniture, clothing, and anything that may have absorbed smoke or collected ash. Open your HVAC vents and photograph inside them. Check closets, attic spaces, and garages. If you can smell smoke, note it. If there’s ash on surfaces inside or out, capture it before you clean anything. Timestamped photos and videos are your single strongest piece of evidence. Do this today, not next week.

2. Don’t accept an early settlement or sign a release

I know it’s tempting to take the money and move on, especially when you’re dealing with the stress of disrupted operations or a damaged property. But early offers almost always leave significant money on the table, particularly when hidden damage hasn’t been discovered yet. Once you sign, you lose your ability to come back for more. Under California insurance regulations, your insurer has 40 calendar days from receiving your proof of claim to accept or deny it, and they’re required to pay any undisputed portions within 30 days. Don’t let anyone pressure you into a decision before you’ve had time to understand the full scope of your losses.

3. Track every dollar you spend as a result of the fire

Temporary repairs or emergency repairs, temporary relocation costs, cleaning services, equipment rental, employee wages during downtime, lost inventory, alternative operating expenses. All of it. Keep receipts, invoices, and records of everything. These are reimbursable costs under most policies, but only if you can prove them.

4. Get independent assessments

Bring in a structural engineer, an environmental consultant, or an HVAC specialist who works for you, not your insurance company. Their findings will give you an objective picture of the damage and provide the documentation you need to support a more accurate claim. California regulations also prohibit your insurer from requiring that you use their preferred vendors for repairs, so you have the right to choose your own professionals.

5. Seriously consider bringing in a public adjuster

A licensed public adjuster is the only type of adjuster who works exclusively on your behalf. They know policy language inside and out, they know how to document complex claims properly, and they negotiate directly with your insurer so you don’t have to. A government study by Florida’s Office of Program Policy Analysis, which analyzed over 76,000 property insurance claims, found that policyholders represented by a public adjuster received settlements that were dramatically higher than those who handled claims on their own. It’s the most widely cited independent study on public adjuster effectiveness, and the results aren’t subtle.

If You’re Negotiating A Claim, We Might Be Able To Help

At Allied Public Adjusters, we’ve been handling fire damage claims across California since 1997. Not as a side service. Not as one thing among many. Insurance claim adjusting is all we do.

We bring a full team to every claim: legal experts, construction experts, engineers, policy analysts, documentation specialists, and experienced negotiators. That matters because fire claims are never just about one thing. There’s structural damage, contents loss, business interruption, code compliance, environmental concerns. Each piece requires specific expertise, and missing even one of them can cost you tens or hundreds of thousands of dollars.

We’ve taken on cases where other public adjusters and attorneys have already walked away, and we’ve delivered settlements averaging 633% higher than what those clients were previously told was “final.”

For business and property owners dealing with the fallout from the Ontario warehouse fire, we’re offering a free consultation to understand your situation and evaluate your policy coverage. From there, we’ll conduct a comprehensive on-site assessment that goes well beyond what’s visible to the naked eye. We prepare a detailed claim package with professional documentation, accurate estimates, and thorough policy analysis. And we handle every conversation and negotiation with your insurance company from start to finish.

You pay nothing upfront. We work on contingency, which means we only get paid when we secure your settlement.

Don’t Sit on This

Evidence doesn’t improve with time. Smoke damage that isn’t documented now becomes harder to prove later. Structural issues that go unidentified can get worse. And your insurance policy almost certainly has deadlines that limit your ability to file or supplement a claim if you wait too long.

If your property or business took any kind of hit from the Ontario Kimberly-Clark warehouse fire, even if you’re not sure whether it rises to the level of a claim, pick up the phone. Let us take a look. That initial consultation costs you nothing, and it could be the difference between an adequate settlement and one that actually covers what you lost.
