Home insurance, also commonly called hazard insurance or homeowners insurance (often abbreviated in the real estate industry as HOI), is the type of property insurance that covers private homes. It is an insurance policy that combines various personal insurance protections, which can include losses occurring to one's home, its contents, loss of its use (additional living expenses), or loss of other personal possessions of the homeowner, as well as liability insurance for accidents that may happen at the home.

The cost of homeowners insurance often depends on what it would cost to replace the house and which additional riders—additional items to be insured—are attached to the policy. The insurance policy itself is a lengthy contract, and names what will and what will not be paid in the case of various events. Typically, claims due to earthquakes, floods, "Acts of God", or war (whose definition typically includes a nuclear explosion from any source) are excluded. Special insurance can be purchased for these possibilities, including flood insurance and earthquake insurance. Insurance must be updated to the present and existing value at whatever inflation up or down, and an appraisal paid by the insurance company will be added on to the policy premium.

The home insurance policy is usually a term contract—a contract that is in effect for a fixed period of time. The payment the insured makes to the insurer is called the premium. The insured must pay the insurer the premium each term. Most insurers charge a lower premium if it appears less likely the home will be damaged or destroyed: for example, if the house is situated next to a fire station, or if the house is equipped with fire sprinklers and fire alarms. Perpetual insurance, which is a type of home insurance without a fixed term, can also be obtained in certain areas.

In the United States, most home buyers borrow money in the form of a mortgage loan, and the mortgage lender always requires that the buyer purchase homeowners insurance as a condition of the loan, in order to protect the bank if the home were to be destroyed. Anyone with an insurable interest in the property should be listed on the policy. In some cases the mortagagee will waive the need for the mortgagor to carry homeowner's insurance if the value of the land exceeds the amount of the mortgage balance. In a case like this even the total destruction of any buildings would not affect the ability of the lender to be able to foreclose and recover the full amount of the loan.

Types of Homeowners Insurance

United States

As described in Wiening et al., prior to the 1950s, there were separate policies for the various perils that could affect a home. A homeowner would have had to purchase separate policies covering fire losses, theft, personal property, and the like. During the 1950s, policy forms were developed, allowing the homeowner to purchase all the insurance they needed on one complete policy. However, these policies varied by insurance company, and were difficult to comprehend. The need for standardization grew so great that a private company based in Jersey City, New Jersey, Insurance Services Office, also known as the ISO, was formed in 1971 to provide risk information and issued a simplified homeowners policy for resell to insurance companies. These policies have been amended over the years until currently, the ISO has seven standardized homeowners insurance forms in general and consistent use . Of these HO-3 is the most common policy followed by HO-4 and HO-6. Others that are less used, though still significant, are HO-1, HO-2, HO-5, and HO-8. Each is summarized below:

In addition, a Dwelling Fire policy is generally available for non-commercial owners of rented houses, covering property damage to the structure, and sometimes to the owner's personal property (such as appliances and furnishings). The owner's liability is generally extended from their own primary home insurance, and does not comprise part of the Dwelling Fire policy. It is a counterpart to the HO-4 renter's policy.
