Wildfire Underinsurance: Are You Covered Enough?
Most homeowners who lose a home in a wildfire discover their policy limit is 20–40% below actual rebuilding cost. Here’s how to know before it happens to you.
Underinsurance is the #1 complaint after wildfire losses. It’s easy to fix before the fire — and nearly impossible after.
Why wildfire underinsurance happens
Underinsurance is rarely deliberate — it’s usually the result of one or more of these four structural problems.
Policy limits set at purchase price, not replacement cost
When you bought your home, your insurer may have set your dwelling limit (Coverage A) to match the purchase price. Market value and rebuilding cost are not the same — and in wildfire-prone regions the gap can be enormous.
Post-disaster construction costs surge 20–50%
When a wildfire destroys dozens or hundreds of homes simultaneously, demand for labor and materials spikes. Contractor rates, lumber, and roofing materials all cost more when everyone needs them at once. Your pre-fire policy limit was never priced for that reality.
Policy limits not updated as home values and costs rose
Construction costs have risen sharply over the past decade. A limit set in 2015 can be badly undersized today even if it included a modest inflation adjustment. Most policies auto-adjust by only 2–4% per year — far below actual cost increases in many markets.
Insurer-selected replacement cost estimates that were too low
Many insurers use automated tools to estimate replacement cost when you first apply. These tools can underestimate — especially for custom finishes, non-standard layouts, and homes in regions where labor costs are above average.
Signs you may be underinsured
If any of these apply to you, your policy may not cover what a rebuild would actually cost.
- !
Your policy's dwelling limit equals or is close to what you paid for the home, not what it would cost to rebuild it from scratch.
- !
Your limit has not been meaningfully reviewed or updated in 5 or more years.
- !
You added square footage, a major kitchen or bathroom renovation, or other significant improvements without notifying your insurer.
- !
You live in a high-demand wildfire zone where construction labor and materials have risen sharply in recent years.
- !
Your policy uses Actual Cash Value (ACV) rather than Replacement Cost Value (RCV) — ACV deducts depreciation from every item.
How to check your coverage
Three concrete steps — you can complete all of them in a week.
Get a replacement cost estimate — not a market value appraisal
A real estate appraisal tells you what your home is worth on the market. What you need is a replacement cost estimate — what it would cost to rebuild the same structure from the ground up at today's prices. A licensed general contractor or a public adjuster can provide one. Your insurer may also offer a more detailed inspection.
Compare that estimate to your dwelling limit (Coverage A)
Open your declarations page and find your Coverage A amount. If the replacement cost estimate is higher — even by 10% — you have a gap. If it's higher by 20% or more, you have a serious underinsurance problem that costs very little to fix.
Ask your insurer about Extended and Guaranteed Replacement Cost riders
Both of these policy endorsements are specifically designed to protect against the gap. ERC (Extended Replacement Cost) adds a buffer above your Coverage A limit. GRC (Guaranteed Replacement Cost) removes the limit entirely. Either is worth the premium increase.
Extended and Guaranteed Replacement Cost explained
Both of these endorsements exist specifically because insurers and regulators recognize that standard policy limits frequently fall short after a major wildfire.
Extended Replacement Cost (ERC)
Adds 20–50% above your Coverage A limit. If you have a $600,000 dwelling limit with a 25% ERC rider, your effective ceiling is $750,000. The most widely available option — most admitted carriers offer it.
Guaranteed Replacement Cost (GRC)
Pays the actual cost to rebuild — regardless of what your Coverage A limit says. No ceiling. Increasingly rare in wildfire-exposed markets, but worth asking about. Both ERC and GRC are worth the premium increase.
Ask your insurer or agent: “Do I have ERC or GRC? If not, what would it cost to add it?” In most cases the premium increase is modest relative to the protection it provides.
What happens if you’re underinsured when a wildfire hits
You pay the gap. If your home costs $800,000 to rebuild and your policy limit is $550,000, you are personally responsible for the $250,000 difference — regardless of whether you have savings to cover it.
There is generally no legal recourse against your insurer for paying exactly what your policy said it would pay — unless the insurer’s own agent provided a negligent estimate that misled you. Even then, proving it is difficult.
An additional complication: even if you have Replacement Cost Value (RCV) coverage, insurers typically pay the depreciated Actual Cash Value (ACV) first. The “recoverable depreciation” is held back and released only after you complete the repairs. If you can’t afford to start rebuilding without the full amount, this creates a cash-flow trap that many homeowners don’t anticipate.
California-specific: the 2018 Wildfire Safety Act
AB 1897 requires California insurers to offer extended replacement cost coverage of at least 20% above the dwelling limit. Insurers must tell you about it — but you have to opt in and pay the additional premium. If your CA insurer never offered it, they may have violated this requirement.
SB 872 extended Additional Living Expenses (ALE) coverage — which pays for your hotel and meals while your home is uninhabitable — to a minimum of 24 months following a declared disaster. This matters because large-scale wildfire rebuilds frequently take two to four years.
Both laws were enacted specifically because legislators observed the scale of underinsurance following the 2017 and 2018 California fires. If you’re a California homeowner, ask your insurer whether your policy meets the AB 1897 ERC floor and whether your ALE duration complies with SB 872.

Wildfire underinsurance FAQ
What is wildfire underinsurance?
Wildfire underinsurance occurs when your homeowner's policy dwelling limit (Coverage A) is lower than the actual cost to rebuild your home after a total loss. After a wildfire, you pay the gap between what your insurer pays and what rebuilding actually costs — out of pocket. Studies of major California wildfires have found that 50–75% of homeowners were underinsured, with average shortfalls of 20–40%.
How common is underinsurance after a wildfire?
Extremely common. After the 2018 Camp Fire and the 2017 Wine Country fires, post-loss surveys found the majority of impacted homeowners were underinsured by significant margins. The California Department of Insurance has cited underinsurance as the single most common complaint following major wildfire events. It is the norm, not the exception.
What is the difference between replacement cost value and actual cash value?
Replacement Cost Value (RCV) pays what it costs to rebuild or replace your home and belongings with new materials of similar kind and quality — without deducting for depreciation. Actual Cash Value (ACV) pays replacement cost minus depreciation, meaning a 15-year-old roof is worth a fraction of what a new roof costs. RCV coverage costs slightly more but is far better coverage for wildfire losses. Many policies pay ACV upfront and release the depreciation holdback only after you actually complete repairs.
Can I sue my insurer if I'm underinsured after a wildfire?
Generally no — not for underinsurance alone. If your insurer correctly paid what your policy said it would pay, you have no breach-of-contract claim even if that amount falls short of rebuilding costs. Exceptions exist: if the insurer's own agent provided a negligent replacement cost estimate that caused you to purchase inadequate limits, some courts have found liability. California has enacted limited protections, including AB 1897, which requires insurers to offer extended replacement cost. Consult an insurance attorney if you believe the insurer misled you.
What is an extended replacement cost rider?
An Extended Replacement Cost (ERC) rider is a policy endorsement that pays above your Coverage A dwelling limit — typically 20–50% more — if rebuilding costs exceed the limit. For example, a $600,000 Coverage A with a 25% ERC rider means the insurer will pay up to $750,000. Guaranteed Replacement Cost (GRC) is even broader: it covers the full actual rebuilding cost regardless of the limit. Both endorsements exist specifically because underinsurance is so common, and both are worth the typically modest premium increase.
