No. Flood's appearance in the National Association of Insurance Commissioners glossary does not mean a U.S. property policy already covers it. The entry calls flood one example of allied lines: coverages generally written with property insurance. "Written with" describes a related line of business, not a promise that each example sits inside every homeowner, renter, or business property contract. The page does not price a flood endorsement, reproduce a declarations page, or state a Canadian coverage rule.
A glossary records a common use of a term. A policy, if one is in force, is the agreement that can require an insurer to pay for a described loss. The fetched page says the definitions represent a common or general use. Treating one of them as a household's proof of payment skips the only paper that can create that proof.
A standing definition, not an October announcement
The page was fetched on October 22, 2026. It is not dated as a news release or a policy change. It is a glossary of terms commonly used in the insurance business, and it says new terms will be added over time. The allied-lines wording below is the wording in this fetch, not a forecast of a later edit.
Staff in the NAIC Research and Actuarial Department develop the definitions from various insurance references. They "represent a common or general use of the term." The introduction warns that other entities may define words differently, or use them so that the shown definition does not apply. That disclaimer limits how far allied lines can be carried into a particular contract or another country's system.
The fetch runs from "Accident" and cuts off during "Asset Risk." Allied lines falls inside that span, so the sentence used here is complete. Later alphabetical entries were not available and are not used.
"Generally written with" is a classification
The entry says allied lines are coverages generally written with property insurance, for example glass, tornado, windstorm and hail; sprinkler and water damage; explosion, riot, and civil commotion; growing crops; flood; rain; and damage from aircraft and vehicle, and so on. The sentence does not rank the examples, set a premium, name a deductible, or say any example is mandatory.
"Coverages" names kinds of protection, not one household's purchased form. "Generally" says the pattern is common rather than universal; the page gives no count of insurers or policies. "Written with" places those coverages in a writing relationship to property insurance. The most direct reading—and this is analysis of NAIC's phrase, not a second definition—is that these coverages are commonly issued in connection with property insurance. The page does not say the connection must be an endorsement, a separate policy, or a clause already inside a base form.
Glass, windstorm, hail, sprinkler and water damage, explosion, riot, crops, flood, rain, and aircraft or vehicle damage are different events and can matter to different buyers. The trailing "etc." marks the list as open: a named example is not thereby granted, and an unnamed peril is not thereby added.
A listed flood peril is still not a claim
The misreading that matters for a U.S. household is to treat that visibility as acceptance of high-water damage. The sentence does not say a homeowner's, renter's, or commercial property policy includes flood. It does not say flood is covered when a contract is silent. It also does not sort flood from "sprinkler and water damage" or from "rain," which sit in the same list. Those neighboring phrases are a reason not to treat every kind of water as one insured peril. The glossary does not define them further, so it cannot do the sorting.
If payment happens, it is because a contract grants the coverage and states the conditions. This glossary contains no such grant. It shows no premium, deductible, or insurer. A reader who cannot point to a declarations page, a form, an endorsement, or a separate flood policy has not found evidence that flood will be paid. Finding the word in the allied-lines entry is not that evidence.
A nearby term should not be asked to fill the gap. "All-risk," also called open peril, means a policy that covers a broad range of losses—the risks not explicitly excluded in the contract. Breadth, on that definition, still belongs to a contract. An allied-lines example is neither the exclusion list nor the covered-peril list of an open-peril form. A dollar cap is a different question. The prior point is enough: a line-of-business label does not place flood inside the contract.
What buyers, including in Canada, still have to read
The practical consequence is a possible false belief about payment, not a documented claim. No household, storm, or dollar loss appears in the source. A U.S. homeowner, renter, landlord, or small business cannot use this entry to estimate a flood premium or to prove that flood coverage is in force. Those steps need contract documents this page does not reproduce.
The glossary states no Canadian statute, provincial form, or rule that flood is included or excluded. Shared wording is not a shared contract. The page's warning that other entities may define a term differently already covers that cross-border use.
"Generally" is not a measured market share. Choosing whether flood is "usually" a separate policy would invent a fact the entry does not give.
What to watch next is concrete. On a later look at the same glossary, check whether allied lines still means coverages generally written with property insurance, whether flood remains only an example, and whether the general-use disclaimer is still there. Separately, read the declarations page, incorporated forms, endorsements, and any distinct flood policy. Those papers can say flood is included, limited, or excluded. Until they do, flood's place on the allied-lines list is classification, not coverage.
