What is the difference between named perils and open perils coverage?

Named perils coverage only protects against specifically listed dangers in your policy (typically 16 standard perils). If damage occurs from a peril not explicitly named, you won't be covered. Open perils (or "all-risk") coverage protects against all potential dangers EXCEPT those specifically excluded in the policy. Open perils provides broader protection but typically costs more. Most HO-3 policies cover dwellings on an open perils basis but personal property on a named perils basis.

Is water damage covered by standard homeowners insurance?

Water damage coverage depends on the source. Sudden and accidental discharge from plumbing, HVAC systems, or appliances is typically covered. However, standard policies exclude flood damage, gradual leaks, sewer backups, and water damage from neglected maintenance. Flood insurance must be purchased separately through the National Flood Insurance Program or private insurers. Water backup coverage can be added as an affordable endorsement to protect against sewer backups and sump pump failures.

Is mold a covered peril?

Mold is usually excluded from standard homeowners insurance. It's considered a maintenance problem or gradual damage rather than a sudden, accidental peril. Some policies offer limited mold coverage when it results directly from a covered peril—for example, mold growth after a burst pipe. For broader mold protection, you may need an endorsement or separate policy.

Are hurricanes and wind damage covered?

Yes. Windstorm and hail are among the 16 named perils, so hurricane wind damage is typically covered. However, in hurricane-prone regions, policies often have a separate wind or hurricane deductible (commonly 1–5% of dwelling coverage) instead of your standard flat deductible. Some coastal areas require additional windstorm coverage or have exclusions. Flood damage from storm surge is never covered by standard homeowners insurance—you need separate flood insurance.

What's the difference between HO-3 and HO-5 for perils?

Both cover the dwelling on an open perils basis. The main difference is personal property: HO-3 covers belongings against 16 named perils only, while HO-5 extends open perils coverage to personal property as well. HO-5 is usually more expensive but offers broader protection for your belongings—useful if you have valuable items or want fewer coverage gaps.

Why are flood and earthquake excluded from standard policies?

Floods and earthquakes typically affect large geographic areas at once, creating catastrophic financial risk that violates the distributed-risk principle insurance relies on. Insurers manage this by excluding these perils and offering them as separate policies or endorsements with their own premiums, limits, and higher deductibles. The National Flood Insurance Program was created to provide government-backed flood coverage that private insurers were reluctant to offer.

Home Insurance Perils | 16 Covered & 4 Exclusions

In homeowners insurance, a peril is any event that can cause damage to your property or belongings—fire, wind, theft, vandalism, and more. Most HO-3 policies cover your dwelling on an open perils basis (everything except what's excluded) and your belongings against 16 named perils. This guide explains what's typically covered, what isn't, and how endorsements can fill gaps. For a broader overview, see what home insurance covers.

Key Takeaways

On a typical HO-3, the structure uses open perils; personal property is covered for the 16 named perils listed below
Named perils and open perils follow different rules for who must prove what in a claim
Standard policies exclude flood, earthquake, and wear and tear; you often need separate policies or endorsements for those risks
Endorsements (for example water backup or scheduled jewelry) can close gaps left by exclusions
After a loss, document everything; in storm-prone areas, wind and hurricane deductibles are often a percentage of dwelling coverage rather than a flat dollar amount

What Is a Peril?

The perils your policy covers directly affect both your premium and your financial protection when something goes wrong. In HO-3 policies, dwelling and other structures usually have open perils coverage, while personal property is typically covered against named perils only. Standard policies exclude floods, earthquakes, and normal wear and tear—often requiring endorsements or separate policies for full protection.

Named Perils vs. Open Perils Insurance Policies

When selecting homeowners insurance, you'll encounter two fundamental approaches to peril coverage: named perils and open perils (also called "all-risk" coverage). Each offers distinct advantages and limitations that directly impact your protection and premium costs.

Named Perils Coverage Explained

A named perils policy covers only those hazards specifically listed in the policy. If a peril isn't explicitly named, damage from that event won't be covered, leaving you financially responsible for repairs or replacements. Named perils policies are typically more affordable but offer more limited protection. They place the burden of proof on you, the policyholder, to demonstrate that damage resulted from one of the specific listed perils covered by your policy.

Named Perils Policy	Open Perils Policy
Covers only specifically listed perils	Covers all perils except those specifically excluded
Lower premium costs	Higher premium costs
Burden of proof on policyholder	Burden of proof on insurance company
Limited coverage scope	Broader coverage scope
Common in HO-1 and HO-2 policies	Standard for dwelling coverage in HO-3 policies

Open Perils (All-Risk) Coverage Explained

Open perils policies take the opposite approach, covering all potential hazards EXCEPT those specifically excluded in the policy. This broader coverage shifts the burden of proof to the insurance company, which must demonstrate that damage resulted from an excluded peril to deny coverage. While open perils policies typically cost more, they provide significantly more comprehensive protection. In most standard HO-3 policies, your dwelling and attached structures are covered on an open perils basis, while personal property is covered on a named perils basis.

The 16 Named Perils (HO-3 Personal Property)

Most HO-3 policies cover personal property against the following 16 named perils. Your dwelling and other structures typically have open perils coverage instead (everything except exclusions).

#	Peril	Notes
1	Fire or lightning	Includes flames, smoke, soot; fire-fighting water damage. Limited or pricier in wildfire zones.
2	Windstorm or hail	Roof, siding, windows. Hurricane zones may have a separate wind deductible (often 1–5% of dwelling).
3	Explosion	Gas leaks, propane, etc.
4	Riot or civil commotion
5	Aircraft	Includes drones.
6	Vehicles	Damage from cars or other vehicles hitting the home.
7	Smoke	Sudden, accidental.
8	Vandalism or malicious mischief	Vacant homes may lose coverage after 30–60 days.
9	Theft	Jewelry, electronics often capped at $1,000–$2,500; schedule high-value items.
10	Volcanic eruption
11	Falling objects	Trees, aircraft parts, etc. Tree from neighbor's yard: often your policy if wind caused it.
12	Weight of ice, snow, or sleet	Collapsing roofs, ice dams. Must show damage from weight, not pre-existing weakness.
13	Accidental discharge or overflow of water or steam	Burst pipes, overflowing appliances. Excludes flood, sewer backup, neglect.
14	Sudden tearing apart, cracking, burning, or bulging	Heating, AC, sprinkler systems, or water-heating appliances.
15	Freezing	Plumbing, HVAC, appliances. Excluded if home was left unheated.
16	Sudden and accidental damage from artificially generated electrical current	Power surges.

Expert Insight: When named vs open perils mattered on a claim

After a hailstorm, Brianna's roof and siding were covered under her dwelling's open-perils coverage. Her damaged patio furniture was covered under personal property because wind and hail are among the 16 named perils on her HO-3. She keeps her declarations page handy so she knows which coverage part applies before she files.

Common Perils Not Covered by Standard Policies

Understanding what isn't covered by your homeowners insurance is just as important as knowing what is covered. The following perils are typically excluded from standard policies but may be available through additional coverage options or separate policies.

Floods and External Water Damage

Flood damage—defined as water entering your home from external sources like heavy rainfall, overflowing rivers, or storm surges—is not covered by standard homeowners insurance. This exclusion often surprises homeowners during catastrophic flooding events. For flood protection, you'll need to purchase a separate flood insurance policy, often through the National Flood Insurance Program (NFIP) or private insurers. Even homes not in designated flood zones can benefit from this coverage, as 25% of flood claims come from properties outside high-risk zones.

Earthquakes and Earth Movement

Standard policies exclude damage from earthquakes, landslides, sinkholes, and other types of earth movement. This exclusion applies nationwide, not just in earthquake-prone regions like California or the Pacific Northwest. Earthquake coverage is available either as an endorsement to your existing policy or as a separate policy. Coverage costs vary significantly based on your location's seismic risk, your home's construction, and your chosen deductible (typically 10-20% of your dwelling coverage).

Mold, Rot, and Pest Damage

Damage from mold, dry or wet rot, and infestations by termites or other pests is generally excluded from standard policies. These issues are typically considered maintenance problems rather than sudden or accidental perils. Some policies offer limited mold coverage if it results directly from a covered peril (like water damage from a burst pipe). For comprehensive protection against these issues, consider separate policies or endorsements specifically covering mold remediation or pest damage.

Wear and Tear or Neglect

Standard insurance doesn't cover damage resulting from normal wear and tear, lack of maintenance, or neglect. Insurance is designed for sudden, unexpected events—not gradual deterioration that occurs over time. Regular home maintenance is your responsibility as a homeowner and is the best way to prevent many common problems. Keep detailed records of home maintenance and improvements, as these can help demonstrate that damage resulted from a covered peril rather than neglect.

Perils and coverage parts (A–F)

Claims are paid under separate coverage parts (A–F), each with its own limits. The sections below are a quick map of how perils tie to each part—limits and dollar amounts are covered on the linked hub pages.

Dwelling and other structures (A & B)

On a typical HO-3, Coverage A (dwelling) and Coverage B (other structures) are insured on open perils—everything except what the policy lists as excluded.

Personal property (C)

Coverage C pays for damage to your belongings under the 16 named perils in the table above (not under the same open-perils wording as the house).

Loss of use (D)

Loss of use (Coverage D) applies when a covered peril makes your home uninhabitable—extra rent, hotel, and similar costs while you’re displaced.

Liability and guest medical (E & F)

Liability (Coverage E) and medical payments to others (Coverage F) address injuries and lawsuits when someone is hurt; they are not coverage for damage to the home from a peril.

Customizing Your Policy with Additional Perils Coverage

Standard homeowners insurance policies don't cover all potential risks. For comprehensive protection tailored to your specific situation, consider these additional coverage options for excluded perils.

Flood Insurance

Flood insurance covers water damage from external sources like heavy rainfall, overflowing bodies of water, or storm surges. Available through the National Flood Insurance Program (NFIP) or private insurers, policies typically provide separate coverage for your dwelling (up to $250,000 through NFIP) and personal property (up to $100,000). Even if you don't live in a designated flood zone, consider flood insurance as a precaution. Just one inch of floodwater can cause up to $25,000 in damage, and approximately 25% of flood claims come from properties in low to moderate-risk areas.

Earthquake Coverage

Earthquake insurance protects against damage from earth movement, including earthquakes, landslides, and sinkholes. Available as an endorsement or separate policy, coverage costs vary significantly based on your location's seismic risk, with deductibles typically set at 10-20% of your dwelling coverage. In high-risk areas like California, earthquake insurance is essential protection. Even in regions with less seismic activity, this coverage can provide valuable protection against unexpected earth movement events that standard policies exclude.

Water Backup Coverage

Water backup endorsements protect against damage from sewer backups, sump pump failures, and drains backing up into your home. This relatively affordable addition (typically $30-$70 annually) covers cleanup, repairs, and personal property damage resulting from these events. This coverage is particularly valuable for homes with basements, aging plumbing systems, or in areas with combined storm and sanitary sewer systems where heavy rainfall can cause backups.

Scheduled Personal Property

For high-value items that exceed standard policy limits, scheduled personal property endorsements provide enhanced coverage with higher limits and broader protection. Items commonly scheduled include jewelry, fine art, collectibles, musical instruments, and expensive electronics. Scheduling items typically requires appraisals or receipts to establish value. Once scheduled, these items are covered for a wider range of perils, often including accidental damage or mysterious disappearance that standard policies don't cover.

Identity Theft Protection

Some carriers offer a small identity theft endorsement (legal fees, credit repair help). It is not a substitute for property peril coverage; treat it as optional add-on coverage.

Filing Claims for Peril Damage

When a covered peril damages your property, document everything with photos and video before making temporary repairs. Keep an updated home inventory with photos and receipts. Note that hurricane and wind deductibles are often a percentage of dwelling coverage (1–5%), not a flat amount—review your policy. If a claim is denied, request a written explanation, gather supporting evidence, and consider your state insurance commissioner or an attorney if needed.

Next steps

Re-read your declarations page for open vs named perils wording, wind/hurricane deductibles if you are in a coastal or storm-prone area, and gaps for flood and earthquake. Update your home inventory after renovations or large purchases. For how each coverage part works and limit-setting, start at what home insurance covers and the coverages hub.
