Earthquake Insurance Is a Separate Policy

By Masud Rana August 20, 2026

Standard homeowners, renters and condominium policies do not cover earthquake damage. The New York Department of Financial Services states it flatly: "Earthquakes are not covered under standard homeowners, renters or condominium policies." The coverage is bought either as an endorsement added to the existing policy or as a separate stand-alone policy, and it carries a percentage deductible rather than a flat dollar one.

This article explains how a policy exclusion and the coverage sold against it are structured. It is educational information, not financial, insurance or legal advice. For a question about your own property, speak to a licensed agent or your state Department of Insurance.

Policy structures checked August 10, 2026. Availability, forms and program rules differ by state and by company, and the authority for what applies to you is your own policy document and your state Department of Insurance.

What the exclusion actually says, and why it is not called "earthquake"

The word on the page is usually broader than the word people search for, and the difference is the whole point of this article.

The California Department of Insurance, in its residential insurance guide, lists what a standard policy leaves out this way: "Earthquake, flood, mold, earth movement, and 'wear and tear' are some of the perils that are usually excluded." Note that earthquake and earth movement appear as two separate items on that list.

That is not redundancy. Earth movement is a family, and earthquake is one member of it. The family also takes in landslide, mudflow, sinkhole collapse, subsidence and the slow settling of ground under a foundation. A policy that excludes earth movement has excluded all of them, and a reader who finds the exclusion, recognizes the word earthquake and buys the obvious product has closed part of the hole rather than all of it.

The rest of what a standard home policy leaves out is set out in what a standard home policy never covers. The exclusion for water from outside is handled separately in why flood is a separate policy.

The two ways the coverage is bought

Flood coverage has essentially one route. Earthquake coverage has two, and which one is available to you is a function of your state and your insurer rather than your preference.

The Washington State Office of the Insurance Commissioner describes both plainly: "You can add it to your homeowner or renter insurance. You can also buy it as separate coverage."

Route one is an endorsement. The coverage is attached to the policy you already have. The declarations page will show it, which means it is visible in the same place as everything else. If you are not sure where to look, how to read an insurance declarations page walks through the layout.

Route two is a stand-alone policy. A separate contract, possibly from a different company, with its own limits, its own deductible and its own effective date. Nothing on the homeowners declarations page will tell you it exists.

The Texas Department of Insurance lists "damage from earthquakes" among the endorsements a Texas homeowner can ask about, which is the first route. The practical consequence of the two-route structure is that "do I have earthquake coverage" is not always answerable from one document.

What an earthquake policy generally covers

The coverage is built to look like a small homeowners policy rather than like a single-purpose add-on, and that surprises people who expect it to pay only for cracks in walls.

The Washington OIC describes coverage for repairs to the home, damage to personal property, debris removal, and additional living expenses during the repair or rebuilding period. It notes that some policies may also reach the cost of meeting current building codes, land stabilization, and other unattached structures.

Two of those are worth pausing on.

Additional living expenses. If the house is not habitable, the same category of cost that a home policy handles after a fire is in play here. What that coverage does and does not pay is covered in loss of use and additional living expense.

Building code costs. Rebuilding to a current code can cost more than rebuilding what was there. Washington's office lists this as something a policy may cover, not something every policy covers, and the difference is in the form you are offered.

What it does not cover, including some earth movement

This is the section the seller-written pages skip, and it is the reason the exclusion and the fix are not the same size.

The Washington OIC's list of what an earthquake policy does not cover includes fire damage, the land itself, vehicles, damage that existed before the earthquake, water damage from outside the home, and then this group: landslides, ground settling, mudflows, earth movement and subsidence.

Read that against the exclusion on the home policy and the shape of the problem appears. The home policy excluded the earth movement family. The earthquake policy, on the description Washington's regulator publishes, does not necessarily take the whole family back. A house damaged by ground settling may sit outside both contracts.

The same page adds a second boundary that matters on a coastline: earthquake coverage "might not cover floods, tidal waves or tsunamis, even when an earthquake causes them." Cause and coverage are not the same question. The peril that responds is the peril the contract names, not the event that started the chain, which is the underlying logic of named perils versus open perils.

None of this means an earthquake policy is a poor product. It means the question worth asking an agent is not "does this cover earthquakes" but "which parts of the earth movement exclusion does this actually give back, and which stay excluded."

The deductible is a percentage, and there may be more than one

Earthquake coverage does not use the flat dollar deductible most homeowners are used to.

Both regulators reviewed here give the same range. The Washington OIC states that earthquake deductibles are "usually 10%-25% of the maximum amount your insurance will pay for your building." The New York Department of Financial Services gives the same 10 to 25 percent range, expressed against replacement value.

Two things follow that a flat deductible never produces.

The dollar amount moves when the coverage amount moves. Raise the building limit and the deductible rises with it, without anybody changing the deductible clause. The mechanics of this are the same as on a wind or hail deductible and are worked through in flat versus percentage deductibles.

There may be more than one. The Washington OIC states that separate deductibles may apply for the building, for contents and for unattached structures. That is unusual. On most property coverage a single loss meets a single deductible. Here, one earthquake can potentially meet three, each calculated against a different limit. Whether that is how a specific policy is built is a question for the form you are offered, and it should be asked before the policy is bought.

Where the insurer gets a say about your house

Earthquake coverage is the one item in this cluster where the physical condition of the building can gate the contract.

The Washington OIC notes that some insurers may require an inspection of the property, and may impose conditions such as bolting the house to its foundation, bracing walls, and strapping fixtures.

That is a different kind of requirement from anything else on a home policy. A deductible or a limit is a term you negotiate on paper. A retrofit condition is work on the building, with a cost and a schedule attached, and it may have to happen before coverage is available rather than after.

For a reader, the useful consequence is one of sequence. If earthquake coverage is something you intend to ask about, ask early enough that an inspection requirement does not arrive as a surprise in the middle of a renewal.

What availability depends on, and the one state rule this article can source

Availability is not uniform across the country, and this article is careful about how far it generalizes.

In California, the regulator states an obligation on the insurer. The California Department of Insurance writes: "When an insurer writes your homeowners coverage, the insurer is legally obligated to offer you earthquake coverage for an additional premium." That is a California statement about California policies, published by California's own regulator.

Outside California, this article makes no claim either way. Whether an insurer in another state must offer earthquake coverage was not something the regulator pages read for this article addressed, and it is not a fact worth guessing at. Your own state Department of Insurance is the authority for your state.

A note on sourcing, because it matters on a topic this state-specific. The California Department of Insurance's dedicated earthquake publication and the Missouri Department of Insurance's earthquake pages could not be retrieved in this research pass. That is why nothing here describes the California Earthquake Authority's own policy terms, and why no figure appears for how common the coverage is anywhere.

How to find out what applies to you

Find the exclusion in your own policy and read the exact words. Look for "earth movement" rather than "earthquake," and note everything the clause sweeps in.
Check the declarations page for an endorsement. If earthquake coverage was added to the policy you already have, it should appear there.
Ask whether a stand-alone policy exists in your name. It will not show on the homeowners declarations page, so the only way to know is to ask, or to look for a separate premium notice.
Ask which parts of the earth movement family the coverage returns, specifically naming landslide, settling and subsidence, and get the answer against the form rather than in general terms.
Ask how many deductibles apply and what each is calculated against.
Ask whether an inspection or a retrofit condition applies before assuming coverage is a paperwork exercise.

Your state Department of Insurance publishes the consumer material this article draws on and handles complaints about how a company administers a policy. The National Association of Insurance Commissioners maintains the directory of state departments. A licensed agent in your state is the right person to tell you what forms are actually available where you live.

This site explains documents and contracts. It does not tell anyone whether to buy earthquake coverage or how much, because that depends on the building, the ground under it, its location and the household's own circumstances, and none of those is visible from here. How sources are chosen on this site is set out in our editorial policy.

Frequently asked questions

Is earthquake coverage part of a standard homeowners policy anywhere?
The regulator publications reviewed here treat it as outside the standard policy. The New York Department of Financial Services states that earthquakes "are not covered under standard homeowners, renters or condominium policies," and the California Department of Insurance lists earthquake among the perils "usually excluded." Your own policy's exclusions section is the authority for your contract.

Why is the deductible a percentage instead of a dollar amount?
That is how the coverage is written. The Washington Office of the Insurance Commissioner describes deductibles of "10%-25% of the maximum amount your insurance will pay for your building," and New York's department gives the same range. The practical effect is that the deductible is tied to the coverage amount rather than fixed, so it moves when the limit does.

Does renters insurance ever include earthquake coverage?
The New York Department of Financial Services names renters policies among those that do not cover earthquakes. The Washington OIC describes earthquake coverage as something that can be added to a renter policy as well as a homeowner policy. So it is an addition rather than something included, and what is available depends on the state and the company.

If an earthquake causes a landslide, which policy pays?
That is exactly the gap this article is about, and the honest answer is that it depends on the wording of both contracts. The Washington OIC lists landslides, ground settling, mudflows and subsidence among what an earthquake policy does not cover, and the home policy has already excluded earth movement. Ask the agent to answer it against the specific forms before you need the answer.

Why Flood Insurance Is a Separate Policy

By Masud Rana August 19, 2026

Standard homeowners and renters policies exclude flood. The Washington Office of the Insurance Commissioner states that a typical home insurance policy "does not cover damage caused by flooding. In fact, they specifically exclude damage or losses from flooding." Flood coverage is bought as a separate policy, generally through the National Flood Insurance Program, and it is normally sold by the same agent or insurance company that sells your home policy.

This article explains how flood coverage is structured and where it comes from. It is educational information, not financial, insurance or legal advice. For a question about your own property, speak to a licensed agent or your state Department of Insurance.

Program terms checked August 6, 2026. The coverage limits and rules described here are program terms that can change. FEMA publishes the current figures at FloodSmart.gov, and that is the authority for what applies today.

The exclusion is not an oversight, and four regulators say so

Every state consumer publication reviewed for this article treats flood as outside the standard policy, and the wording is not tentative.

The Washington Office of the Insurance Commissioner states that home policies "specifically exclude damage or losses from flooding." The New York Department of Financial Services states that insurance coverage for losses from floods is not provided in standard homeowners or tenants policies. The North Carolina Department of Insurance states flatly that "Homeowners insurance policies do not cover flood damage." The South Carolina Department of Insurance frames it as the thing consumers most often get wrong: "Most people don't realize that their homeowners insurance doesn't typically cover flood."

So this is not an exclusion that varies much by policy, in the way that some others do. It is a structural boundary between two different contracts. The broader question of what else a home policy leaves out is covered in what a standard home policy never covers.

What "flood" means in this context

The word does a lot of work here, and it is worth noting that not every water event is a flood in the sense the exclusion uses.

The North Carolina Department of Insurance describes the federal program as offering insurance for "direct flood and flood related damage including mudslide and erosion." So the flood contract reaches beyond water alone.

At the same time, the home policy's own exclusions include water events that are not floods. The California Department of Insurance lists water damage caused by seepage or leaks among perils generally not covered, and the Texas Department of Insurance names sewer backups. Those are separate exclusions with separate answers, and a flood policy is not automatically the place they land.

The practical consequence is that "my house had water in it" is not enough information to know which contract, if any, responds. Which one applies depends on the source of the water, and the source is defined in the policy documents rather than by how the damage looks.

Where the coverage comes from instead

Flood coverage is generally available under a separate policy issued through the National Flood Insurance Program, in the New York Department of Financial Services' words. The Washington Office of the Insurance Commissioner describes flood insurance as "widely available through the National Flood Insurance Program."

The important structural point for a reader holding a home policy is that this is a different contract with its own terms, its own limits, its own deductible and its own effective date. It is not an endorsement bolted onto the homeowners policy, and nothing on the homeowners declarations page will tell you whether you have it. If you are still mapping what is on that page, the six coverage parts A through F and how to read an insurance declarations page cover the layout.

A note on this article's sourcing, since it matters for a program page. FEMA's own website and FloodSmart.gov could not be retrieved in this research pass, so every program fact below is sourced to a state insurance regulator publication that was read directly, and the reader is pointed to FEMA for anything current. That is a limitation stated rather than papered over.

Who actually sells you the policy

This is the half of the question most explanations skip, and the answer has two parts that people often collapse into one.

Where you buy it. From your ordinary insurance agent or company. The North Carolina Department of Insurance states that "Your agent or insurance company can assist you with application forms for flood coverage." The Washington Office of the Insurance Commissioner describes buying it from an agent, a broker, or the program itself. The Texas Department of Insurance gives the same route and adds a fallback: "Talk to your home insurance agent about getting a flood policy from your insurance company or the NFIP. If your agent doesn't sell flood insurance, call 877-336-2627."

Who stands behind it. The federal program. That is why the coverage terms do not vary between sellers the way home insurance terms do, and it is why an agent cannot negotiate the coverage the way they might discuss endorsements on a home policy.

The practical implication is that shopping a flood policy is not the same activity as shopping a home policy. There is a market in service and in some cases in private alternatives, but the standard product's terms come from the program.

There is also a private and surplus-lines market alongside the program. The Washington Office of the Insurance Commissioner notes that a household wanting more coverage "can purchase excess flood coverage," and that a policy from a surplus line insurer usually starts immediately. Those are different products with different rules, and a licensed agent is the right person to explain what is available in a given state.

Your community has to be in the program

Here is the eligibility fact almost no consumer page carries, and it is the one that can stop a willing buyer.

The North Carolina Department of Insurance states that the federal program "requires that the community in which you live adopt zoning laws that prohibit future building in flood prone areas." The New York Department of Financial Services tells consumers to "find out if your community participates in the NFIP."

Read together, that means availability is partly a decision your local government made, not one you make. A household can want the coverage, have the money for it, and still be outside the program because of where the property sits and what that jurisdiction has adopted.

This is worth checking before anything else, because it determines whether the rest of the process is even available. Your agent can tell you, and FEMA publishes the participating-community information.

Building and contents are two separate purchases

A household that buys flood insurance and stops after one transaction may have covered the structure and nothing inside it.

The Texas Department of Insurance is explicit about the split. A flood policy "will cover your home up to $250,000," and for belongings "you'll need a separate flood policy for your personal belongings, which provides coverage up to $100,000." The New York Department of Financial Services describes the contents coverage as available for an additional premium, up to the same figure. The Washington Office of the Insurance Commissioner gives the same two residential numbers, and adds the commercial figures of $500,000 on a building and $500,000 for contents.

Those figures are published by the Texas Department of Insurance as updated August 7, 2025 and by Washington's office on a page citing FEMA material dated 09-2024. They are program terms, they can change, and the current version is published by FEMA at FloodSmart.gov. Do not treat the numbers in this article as current on the day you read it.

Two consequences of the structure, neither of which is advice:

Renters have only one of the two to think about. There is no building to insure, so contents coverage is the whole question.

Homeowners can end up with a gap they did not choose. If the building coverage was arranged through a lender requirement and nobody raised the second policy, the contents may simply never have been bought.

The relationship between a limit, a deductible and what a household actually absorbs is the same on this contract as on any other, and is covered in premium, deductible, limit, out-of-pocket.

The 30-day wait, and the two documented exceptions

Flood coverage does not start when you pay for it. This is the single most consequential procedural fact on the page.

The New York Department of Financial Services states that "A flood insurance policy normally will not go into effect until 30 days after you purchase the policy." The North Carolina Department of Insurance describes "a 30-day waiting period before the policy becomes effective; however, there are exceptions," without listing them. The Texas Department of Insurance gives the same rule with the practical warning attached: "Most flood policies have a 30-day waiting period before kicking in so don't wait for an approaching storm."

The Washington Office of the Insurance Commissioner is the one source reviewed here that names an exception. It states that program policies "start covering your building 30 days after the policy is written, unless the policy is required for a mortgage." It separately notes that a policy from a surplus line insurer usually starts immediately, which is a different product rather than an exception to the program rule.

The reason this matters more than it looks is timing. A household that decides to buy when weather is forecast has, in the ordinary case, already missed the window. Whether any exception applies to a specific purchase is a question for the agent writing it, and it should be asked before the policy is bought rather than after.

One more fact worth carrying, because it changes who thinks this page is about them: the Texas Department of Insurance states that 40 percent of program flood insurance claims occur outside the high-risk flood areas. Being outside a mapped high-risk zone is not the same as being outside the risk.

How to find out what applies to you

Confirm the exclusion in your own policy by reading the exclusions section of the home or renters form. The flood exclusion should be there in writing.
Check whether your community participates in the program. Your agent can confirm, and FEMA publishes it. This gates everything else.
Ask your own agent first, since the same agent who wrote the home policy commonly writes this one. If they do not, the Texas Department of Insurance publishes 877-336-2627 as the route to find one who does.
Establish whether you are buying one coverage or two. Ask specifically about contents as a separate item, not as part of the building conversation.
Ask when coverage starts, in writing, and whether any exception applies to your purchase.
Confirm the current limits at FloodSmart.gov rather than from any article, including this one.

This site explains documents and contracts. It does not tell anyone whether to buy flood coverage or how much to buy, because that depends on the property, its elevation, its location and the household's own circumstances, and none of those is visible from here. How sources are chosen on this site is set out in our editorial policy.

Frequently asked questions

Can I add flood coverage to my homeowners policy instead?
The state material reviewed here describes flood as a separate policy rather than an addition to the home policy. The New York Department of Financial Services states that flood coverage "is generally available under a separate policy issued through the National Flood Insurance Program." Your agent can confirm what is available in your state.

Do I need flood insurance if I am not in a flood zone?
That is a decision this site does not make for anyone. The relevant fact is that the Texas Department of Insurance states 40 percent of program flood claims occur outside high-risk flood areas, so location outside a mapped zone is not the same as absence of risk. A licensed agent can discuss a specific property.

Why is there a waiting period?
The rule is part of the program's terms. Several regulators state it plainly: coverage normally begins 30 days after purchase. Washington's Office of the Insurance Commissioner names one documented exception, where the policy is required for a mortgage. Whether an exception applies to a particular purchase is a question for the agent writing it.

Does renters insurance cover flood?
The New York Department of Financial Services states that coverage for flood losses is not provided in standard homeowners or tenants policies. Contents flood coverage is bought separately, and it is the only one of the two coverages a renter has to consider, since there is no building to insure.

What Homeowners Insurance Does Not Cover

By Masud Rana August 18, 2026

Three causes of loss are excluded from a standard homeowners policy in every state consumer guide reviewed here: flood, earthquake, and wear and tear. Beyond those three the lists diverge, and commonly include earth movement, termites and other pests, mold, seepage, neglect, war and nuclear hazard. Exclusions are not one category. Some are excluded outright, some are insurable under a separate contract, and some are excluded because they are maintenance rather than sudden events.

This article explains how exclusions are structured in a policy you already hold. It is educational information, not financial, insurance or legal advice. For a question about your own coverage, speak to a licensed agent or your state Department of Insurance.

This page is about the contract before anything has happened. It does not cover what to do after a loss, how a claim is handled, or how a settlement is reached. Those are different subjects with different answers.

The short answer, and the regulators who agree on it

Four state insurance regulators publish lists of what a standard homeowners policy does not cover. Three items appear in all four.

Flood. The Iowa Insurance Division states plainly that "Floods, wear and tear, and earthquakes are excluded perils." The North Carolina Department of Insurance lists flood among losses typically not covered. The New York Department of Financial Services states that flood coverage is generally always excluded from homeowners and tenants policies. The California Department of Insurance lists flood first among perils generally not covered.

Earthquake. The same four. California lists both earthquake and earth movement as separate entries.

Wear and tear. California lists "Wear and tear or maintenance." Texas lists wear and tear. Iowa names it in the sentence above.

Everything past those three varies, and the variation is itself useful information.

Four state lists, side by side

Here is what each regulator actually publishes. Empty cells mean the item was not named in that publication, not that it is covered.

Excluded cause	California	Texas	North Carolina	Iowa
Flood	yes	yes	yes	yes
Earthquake	yes	yes	yes	yes
Earth movement, mudslide, mudflow, landslide	yes		yes
Wear and tear, maintenance	yes	yes		yes
Termites, insects, rats or mice	yes	yes (termites)
Mold	yes	yes (mold removal)
Water damage from seepage or leaks	yes
Sewer backup		yes
Foundation repairs		yes
Neglect	yes
War, insurrection	yes
Nuclear hazard	yes
Tidal wave	yes
Windstorm or hail			may be excluded, purchasable separately

The California Department of Insurance list is the fullest of the four. Its residential insurance guide, issued as Form 401 and revised January 2026, names as perils generally not covered: "Flood, Earthquake, Earth movement, Termites, Insects, rats or mice, Water damage cause by seepage or leaks, Mold, Wear and tear or maintenance, War, Insurrection, Tidal wave, Neglect, Nuclear hazard."

The Texas Department of Insurance, in a tip page updated September 29, 2025, states that coverage on an all-risk policy typically excludes termites, wear and tear, sewer backups, floods, earthquakes, mold removal and foundation repairs.

The North Carolina Department of Insurance lists losses from "floods, earthquakes, mudslides, mudflows or landslide" as typically not covered, and separately notes that windstorm and hail may be excluded from a policy and purchased separately.

The Iowa Insurance Division, in a consumer guide published April 4, 2024, gives the three-item version quoted above.

Four official publications, four different lists, one overlapping core. No one of them is your policy.

Kind one: excluded outright

Some exclusions have no ordinary route back into coverage for a household. War, insurrection and nuclear hazard are the clearest examples, and California names all three.

These are excluded because of the nature of the risk rather than because of anything about a particular property. There is nothing on the reader's side to do about them, no endorsement in the ordinary consumer market that reverses them, and no reading of the policy that finds coverage. They are worth knowing about mainly so that they are not confused with the next two kinds, which behave completely differently.

Intentional acts belong in a related category. The North Carolina Department of Insurance notes that personal liability coverage excludes intentional acts, which is a limit on the coverage rather than a peril in the usual sense.

Kind two: excluded here, insurable somewhere else

This is the group that matters most, because being excluded from the homeowners policy is not the same as being uninsurable.

Flood. The New York Department of Financial Services states that flood is generally always excluded from homeowners and tenants policies, and that the coverage is purchased separately through the federal program. This is not an exclusion a household can argue about. It is a boundary between two different contracts, and it is covered separately in why flood is a separate policy.

Earthquake. Excluded in all four states' material, and available separately. The California Department of Insurance goes further than the others and states that an insurer is legally obligated to offer earthquake coverage for an additional premium, which is a state-specific rule rather than a national one.

Windstorm and hail. The North Carolina Department of Insurance notes these may be excluded from a policy and purchased separately. That structure is not universal, it is a feature of certain markets, and it is the reason a national list of exclusions can be misleading in a coastal state.

The reading instruction for this group is different from kind one. When one of these appears in your exclusions, the next question is not whether the policy covers it, because it does not. The next question is what separate contract exists for it in your state, and that is a question for a licensed agent or your state Department of Insurance.

Kind three: excluded because it is maintenance, not an event

The third group is where most disagreements actually start, and it is the least understood.

California's list names wear and tear or maintenance, neglect, termites, insects, rats or mice, mold, and water damage caused by seepage or leaks. Texas names wear and tear, termites, mold removal, sewer backups and foundation repairs.

What connects these is not the type of damage, it is the shape of the cause. A homeowners policy is built to respond to a sudden, identifiable event. Deterioration over time is not that. A leak that develops slowly, an infestation that establishes itself, a foundation that settles across years, a material that ages out are all outcomes rather than events, and the policy does not treat them as insurable losses.

Two consequences follow, and neither is advice.

The first is that the boundary between kind three and a covered loss can be genuinely fine, because a sudden failure and a slow one can produce identical looking damage. Where that line falls is set by the policy language, not by how the damage looks.

The second is that sewer backup appears on the Texas list as a typical exclusion, and it is one that many policies address through an endorsement. Whether yours does is a question about your own form and endorsement list.

"Excluded" is not the same as "not covered"

There are two different ways a cause of loss can end up outside a policy, and only one of them is an exclusion.

On an open peril policy, coverage is stated broadly and then narrowed by an exclusions list. A cause is outside the policy because it is named in that list. This is where the word exclusion belongs.

On a named peril policy, coverage exists only for causes the policy lists. A cause can be outside the policy simply because it is not on the list, without being excluded anywhere. Nothing has been carved out. It was never in.

The practical difference is where to look. On an open peril policy the exclusions section is the boundary of the coverage. On a named peril policy the covered perils list is the boundary and the exclusions section is secondary. Which structure your policy uses is covered in named perils vs open perils.

A reader who does not separate these two can spend a long time searching an exclusions list for something that was never going to be there.

Why no published list is your list

Every list on this page, including the ones from state regulators, is a summary of what policies in a particular market commonly do. None of them is a policy.

Three reasons the general list and the specific one diverge:

Insurers file their own forms. Policy wording is filed and approved state by state, so two policies sold under the same form number in two states can read differently.

Endorsements modify the base form. An endorsement can add coverage back, remove more, or attach conditions. Endorsements are listed on your declarations page by form number, and the exclusions in your policy are the base form's exclusions as modified by every one of those.

Markets differ. North Carolina's material discusses windstorm and hail as separately excludable. California's discusses earthquake as something an insurer must offer. Neither statement travels.

That is why the useful output of an article like this is not the list. It is knowing what kind of thing each exclusion is, and knowing where in your own paperwork the governing version is written. The rest of the structure of that paperwork is covered in the six coverage parts A through F and in how to read an insurance declarations page.

How to read your own exclusions section

Get the policy form, not the declarations page. Exclusions live in the form. If it is not in hand, ask your insurer for it by the form number printed on your declarations page.
Find the section headed Exclusions. On many forms there is more than one, because Section I property and Section II liability carry their own.
Sort what you find into the three kinds above. Outright, insurable elsewhere, and maintenance. Each kind has a different next step, and only the second one has anything to buy.
Read the endorsement list on the declarations page and get any endorsement that mentions an exclusion, since that is where the base form gets modified.
Check whether a separate deductible attaches to any excludable peril in your market. Where a peril is covered under a separate arrangement it often carries its own deductible, and how those are written is covered in flat vs percentage deductibles.

For anything past reading the document, a licensed insurance agent can explain what a specific exclusion or endorsement does. Your insurer's service line can send you the forms. Your state Department of Insurance publishes the consumer material this article draws on and handles complaints about how a company administers a policy, and the National Association of Insurance Commissioners maintains the directory of state departments.

This site explains documents. It does not tell anyone which endorsements to carry, and it does not evaluate whether a particular exclusion is fair, because both of those depend on facts about a household and a property that no article can see.

Frequently asked questions

Is flood ever covered by a homeowners policy?
The state material reviewed here treats it as excluded. The New York Department of Financial Services states that flood coverage is generally always excluded from homeowners and tenants policies and that the coverage is bought separately through the federal program. Iowa, North Carolina and California all list flood among perils not covered.

Why is water damage sometimes covered and sometimes not?
Because the exclusions are written around the shape of the cause rather than the type of damage. California's list names "Water damage cause by seepage or leaks" as generally not covered, and Texas names sewer backups. A sudden failure and a slow one can look the same afterward, and the policy language, not the appearance, is what governs.

If a cause is not on my exclusions list, is it covered?
Only if your coverage is written on an open peril basis. On a named peril policy, a cause has to appear on the covered perils list to be covered, and absence from the exclusions list means nothing. Check which structure your policy uses first.

Do all states have the same exclusions?
No. The four regulator publications compared above overlap on flood, earthquake and wear and tear and diverge after that. North Carolina discusses windstorm and hail as separately excludable, and California states that insurers there are legally obligated to offer earthquake coverage. Policy forms are filed state by state, so your own form is the only reliable source.
