Key Takeaways
- Standard home insurance does not cover flood or earthquake damage — separate policies are required.
- Insurers typically pay to rebuild your home, not reimburse what you paid for it.
- Filing a small claim can raise your premium more than the payout is worth.
- Home-based businesses and their equipment usually require separate coverage.
- Personal belongings are often covered at actual cash value, not replacement cost, by default.
Why These Myths Matter
Homeowners insurance is one of the most significant financial protections most American families carry — and one of the least understood. A common set of misconceptions quietly leads people to carry policies that won't perform the way they expect when something goes wrong.
This isn't about scare tactics. It's about knowing what you actually have so you can decide whether it's enough. The myths below are among the most consequential ones, drawn from the kinds of misunderstandings that regularly leave homeowners facing out-of-pocket costs they didn't anticipate. For a broader look at coverage gaps, see why people end up underinsured.
Myth
My home insurance will pay out what I paid for the house, so I'm covered for whatever it costs to rebuild.
Fact
Standard policies are based on rebuilding cost, not market value or purchase price — and those figures can differ significantly.
Your home's market value includes the land it sits on and local real estate conditions. Insurance doesn't cover land — it covers the structure. In many markets, a home's market value and its rebuild cost are quite different numbers. After a major disaster, when labor and materials are in high demand, rebuild costs can spike well above normal estimates. Homeowners who set their dwelling coverage based on what they paid — or what Zillow shows — may find themselves hundreds of thousands of dollars short. Ask your insurer about a replacement cost estimator and review that figure periodically.
Myth
Flood damage is covered under a standard homeowners policy.
Fact
Flooding is explicitly excluded from virtually all standard homeowners policies. It requires a separate flood insurance policy.
This is one of the most expensive misconceptions in home insurance. Standard policies cover sudden water damage from inside the home — like a burst pipe — but not flooding from outside, whether from a storm surge, overflowing river, or heavy rain runoff. Flood insurance is available through the federal National Flood Insurance Program (NFIP) and some private insurers. Importantly, there is typically a 30-day waiting period before a new NFIP policy takes effect, so buying it the day before a storm doesn't help. Many homeowners in lower-risk flood zones skip it, not realizing floods occur outside high-risk zones too.
Myth
Earthquakes are covered because my policy covers 'natural disasters.'
Fact
Earthquake damage is a standard exclusion in homeowners policies across the US. A separate earthquake policy or endorsement is needed.
The phrase "natural disaster" doesn't have a consistent meaning in insurance contracts — coverage is determined by what perils are specifically listed or excluded, not broad categories. Earthquakes, like floods, are almost universally excluded from standard homeowners policies. This applies not just to California but to states with significant seismic risk that homeowners may not expect, including Oregon, Washington, Utah, and parts of the Midwest and South. Earthquake coverage is available as a separate policy or, in some cases, an endorsement added to an existing policy.
Myth
I should file a claim for every loss — that's what insurance is for.
Fact
Filing small or frequent claims can raise your premium or even result in non-renewal, sometimes costing more than the claim payout.
Insurers track claims history, and multiple claims within a short window can flag you as a higher risk. Some companies use a database called CLUE (Comprehensive Loss Underwriting Exchange) that records claims for up to seven years. Filing a claim for a $900 loss when your deductible is $1,000 accomplishes nothing. Filing for a $1,500 loss might net you $500 after the deductible — but if it raises your annual premium by $300 and puts your policy in jeopardy, the math may not work in your favor. It's worth speaking with your agent before filing a claim for smaller losses.
Myth
My home-based business equipment and inventory are covered under my homeowners policy.
Fact
Most homeowners policies have strict limits — often $2,500 or less — on business property, and exclude business liability entirely.
As more Americans work from home or run side businesses, this gap has become increasingly consequential. A standard policy might cover a small amount of business equipment, but professional tools, inventory, and business-related liability are typically excluded or severely capped. If a client visits your home and is injured, your homeowners liability coverage may not apply to that incident. A home business endorsement or a separate business owner's policy (BOP) is usually needed to close these gaps. This is an area worth reviewing explicitly with a licensed agent.
Myth
My personal belongings are covered at their full replacement value by default.
Fact
Many standard policies pay actual cash value (ACV) for personal property — meaning depreciation is deducted before you receive anything.
Actual cash value accounts for age and wear. A five-year-old laptop that costs $1,200 to replace today might only receive $400 under an ACV payout. Replacement cost value (RCV) coverage pays what it actually costs to replace the item with a comparable new one, and it's available as an upgrade on most policies — but it typically costs more in premium. Homeowners who haven't reviewed this distinction may assume they'll be made whole after a theft or fire, only to receive far less. Check your declarations page to confirm which standard applies to your personal property coverage.
Where to Go From Here
If any of these myths sounded familiar, that's not unusual — they persist because the insurance industry communicates poorly and most people only think about their policy when something goes wrong. A licensed insurance agent can walk you through your specific declarations page and help you identify gaps before they cost you.

Homes estimated to be underinsured
Industry analyses have consistently estimated that a significant share of US homes carry dwelling coverage below their actual rebuild cost.

Flood claims outside high-risk zones
According to FEMA, roughly one quarter of flood insurance claims come from properties outside designated high-risk flood areas.
$2,500
Typical business property limit in home policies
Many standard homeowners policies cap coverage for on-premises business property at $2,500 or less, far below what most home-based businesses own.
It also helps to understand the full picture of what standard policies exclude. What standard home insurance policies don't cover is a useful companion read, as is our breakdown of what you're actually paying for on your insurance bill. If you rent rather than own, the differences between homeowners and renters insurance are worth understanding too.
Review Your Policy Before You Need It
Most homeowners only read their policy documents after a loss — by which point it's too late to change coverage. Set a reminder to review your declarations page at each renewal. Pay particular attention to your dwelling coverage limit, personal property valuation method, and any listed exclusions. If something isn't clear, ask your agent to explain it in writing.
