What Perils Does Homeowners Insurance Cover? Named vs. Open-Peril

The perils covered by homeowners insurance fall into two groups: a specific list of 16 events that trigger coverage for your belongings, and a much broader set of causes that are covered for the house itself unless the policy specifically excludes them. The standard policy most people carry, the HO-3, handles the dwelling on this open basis while limiting personal property to the named list. Floods, earthquakes, gradual damage, and poor maintenance sit outside both sides of that coverage.

The 16 Named Perils

These are the events a standard policy lists by name as triggering coverage for personal belongings, and in some policy forms for the structure as well:

  • Fire or lightning, including associated power surges
  • Windstorm or hail, including wind-driven rain or snow that enters after the home is breached
  • Explosion, such as from a gas leak or a propane tank failure
  • Riot or civil commotion
  • Damage caused by aircraft, including drones
  • Damage caused by vehicles striking the home or its structures
  • Smoke, excluding smoke from industrial or agricultural operations
  • Vandalism or malicious mischief
  • Theft, including damage from forced entry
  • Falling objects, from tree limbs to meteors
  • Weight of ice, snow, or sleet on the roof or structure
  • Accidental discharge or overflow of water or steam from plumbing, water heaters, or HVAC systems
  • Sudden and accidental tearing apart, cracking, burning, or bulging of water heaters, boilers, and similar systems
  • Freezing of plumbing, heating, air conditioning, or fire sprinkler systems, provided reasonable steps were taken to maintain heat
  • Sudden and accidental damage from artificially generated electrical current
  • Volcanic eruption (but not earthquake damage, even if volcanic activity triggered it)

This list is the backbone of what gets paid when something happens to your belongings. For the house itself, the picture is wider, and that depends on which policy form you carry.

Named-Peril vs. Open-Peril Coverage

A named-peril policy covers only the events on its list. If damage comes from something not listed, there is no payout, and the homeowner has to show the loss was caused by a listed peril.1Insurance Geek. Home Insurance Perils

An open-peril policy, sometimes called all-risk, works the opposite way. Everything is covered unless the policy specifically excludes it, and the insurer carries the burden of proving an exclusion applies.1Insurance Geek. Home Insurance Perils

The HO-3, which mortgage lenders typically require, blends the two. The dwelling and other structures get open-peril coverage. Personal property gets named-peril coverage limited to those 16 events.2Progressive. Homeowners Policy Types3Texas Department of Insurance. All-Risk or Named Peril Home Insurance Policies

Other forms shift the balance. An HO-2 covers all 16 perils for both the dwelling and personal property, but on a named-peril basis for each. An HO-5 extends open-peril coverage to both the dwelling and personal property, and typically reimburses property losses at replacement cost rather than depreciated value.2Progressive. Homeowners Policy Types4Andover Companies. Difference Between HO-3 and HO-5 Homeowners Policy The older HO-1 is more limited, covering just 10 of the perils and leaving out falling objects, weight of ice and snow, and water-related losses; most lenders won’t accept it, and many insurers no longer sell it.5Tiger Adjusters.

Renters have HO-4 policies, condo owners have HO-6, manufactured and mobile homes get HO-7 coverage, and older homes whose replacement cost far exceeds market value are often written on the modified HO-8 form.7South Carolina Department of Insurance.

What Standard Policies Exclude

Even open-peril coverage has significant gaps. The following are excluded from a standard homeowners policy regardless of form:

Water Damage: What’s Covered and What Isn’t

Water damage trips up more homeowners than any other category because the policy splits sharply between sudden losses and gradual ones.

Covered: a burst pipe, a ruptured water heater, an overflowing washing machine, a toilet that suddenly fails. The resulting damage to walls, floors, and belongings is paid under the accidental discharge peril. One catch: the policy generally will not pay to repair or replace the broken appliance or pipe itself.12Allstate. Water Damage13Texas Department of Insurance. When Are Water Damage and Mold Covered by Insurance

Not covered: flooding from storms, rivers, or storm surge; gradual leaks that develop over time; water seeping up through the foundation; and sewer or drain backups. Frozen-pipe damage may be excluded if heat wasn’t maintained in the building.12Allstate. Water Damage Mold that follows a covered sudden water loss can receive limited coverage; mold from a slow leak or a flood will not.13Texas Department of Insurance. When Are Water Damage and Mold Covered by Insurance

Filling the Gaps: Flood, Earthquake, and Endorsements

Flood Insurance

Because flooding is universally excluded, flood protection requires a separate policy. The main source is the National Flood Insurance Program, run by FEMA, which offers up to $250,000 in building coverage and $100,000 for contents. The NFIP is available in more than 22,600 participating communities and is mandatory for properties in high-risk flood zones carrying government-backed mortgages. Policies generally take 30 days to take effect.14FEMA. Flood Insurance15FloodSmart.gov. Buy a Policy Private flood policies are also expanding; Florida law establishes multiple tiers of private flood coverage, some with broader protection or higher limits than the NFIP.16Florida Office of Insurance Regulation. Flood Insurance

Earthquake Insurance

Earthquake damage requires a standalone policy or an endorsement on the existing one. Deductibles tend to be high and are calculated as a percentage of the home’s insured value rather than a flat dollar amount. Premiums depend on construction (wood-frame homes generally cost less to insure than masonry), number of stories, and age of the building.17Nebraska Department of Insurance. Earthquake Coverage Requires Separate Policy or Endorsement One wrinkle: fire or water damage triggered by an earthquake, such as from a ruptured gas line or water pipe, may still be paid under the standard policy’s fire or water perils even if there’s no earthquake coverage.18North Carolina Department of Insurance. Earthquake Coverage

Endorsements That Extend Coverage

Endorsements, also called riders, are add-ons that widen what the base policy pays for. Common options include:

  • Water and sewer backup coverage, for damage from backed-up drains, clogged sewer lines, and failed sump pumps. Annual premiums commonly run $50 to $250, with limits often between $5,000 and $25,000 per occurrence, and some insurers offering limits up to the home’s full replacement cost.19The Hanover. Answers to Questions About Water Backup20Insurance.com. Water Backup Insurance
  • Scheduled personal property, which raises limits for jewelry, fine art, and collectibles and often broadens the perils covered on those items.21Allstate. What Is an Insurance Rider
  • Building code (ordinance or law) coverage, which pays the extra cost of bringing a damaged home up to current codes during repairs.21Allstate. What Is an Insurance Rider
  • Home systems protection, for major systems and appliances that fail from mechanical or electrical breakdown.22Mercury Insurance. The Value of Home Insurance Endorsements
  • Service line protection, for underground utility lines running from the street to the home.22Mercury Insurance. The Value of Home Insurance Endorsements
  • Mold endorsements, which some states regulate directly. Texas requires insurers to offer mold “buyback” endorsements at 25%, 50%, or 100% of policy limits. Florida insurers commonly offer mold limits of $25,000 or $50,000.23Texas Department of Insurance. Commissioner’s Order CO-01-110524Florida CFO. Policy Endorsements

Some states require insurers to at least offer certain endorsements. Virginia, for instance, mandates that every policyholder be offered both water and sewer backup coverage and building ordinance coverage.25Virginia State Corporation Commission. Virginia Homeowners Insurance Guide

How Much the Policy Pays: ACV vs. Replacement Cost

Even for a clearly covered peril, the dollar amount paid depends on how the policy values the loss.

Actual cash value subtracts depreciation. The insurer calculates what it would cost to repair or replace the item, then reduces that figure for age and wear. The result can fall well below the price of a new replacement. On a 20-year-old roof with a $10,000 replacement cost and a $4,000 deductible, depreciation can wipe out the payout entirely.26Texas Department of Insurance. Home Insurance Policies: Replacement Cost or Actual Cash Value

Replacement cost coverage pays current prices without depreciation, usually in two stages. The insurer first pays the actual cash value, then releases the remaining amount, called recoverable depreciation, once the homeowner finishes repairs and submits receipts.27North Carolina Department of Insurance. Actual Cash Value vs. Replacement Cost Value28NAIC. What’s the Difference Between Actual Cash Value Coverage and Replacement Cost Coverage

Peril-Specific Deductibles

Most policies carry one flat-dollar deductible for ordinary claims like fire and theft. In regions exposed to hurricanes, windstorms, or hail, a separate deductible applies to those specific perils and is usually a percentage of the dwelling coverage rather than a dollar figure.

A hurricane deductible typically runs 1% to 5% of the dwelling limit and replaces the standard deductible when the National Weather Service recognizes the storm as a hurricane. On a home insured for $300,000, a 2% hurricane deductible means $6,000 out of pocket before any coverage kicks in. Named-storm deductibles work the same way but cover a broader category of weather events, including tropical storms. Wind and hail deductibles may be flat-dollar or percentage-based and apply to any wind or hail damage, not just named storms.29NAIC. Hurricane Deductibles30Progressive. What Is a Hurricane Deductible

States set some limits on these figures. Maryland caps percentage-based hurricane or storm deductibles at 5% of the coverage limit unless the insurance commissioner approves a higher figure in writing.31Maryland Insurance Administration. Homeowners Insurance Guide Arkansas requires that every deductible, including peril-specific ones, be disclosed on the declarations page.32NCSL. Homeowners and Renters Insurance Legislation

Before assuming a loss will be paid, check two things in the declarations page: the policy form (HO-1 through HO-8 determines whether your dwelling has open or named-peril coverage) and the deductible schedule (a hurricane or wind deductible can turn a covered claim into a mostly out-of-pocket repair). The named perils, the exclusions, and the valuation method together decide what the policy actually does when something goes wrong.
