Homeowners insurance companies do not cover landslides or mudslides because of their rarity and the extensive damage they cause. Some may argue that other named perils, such as hurricanes that can cause landslides and mudslides, should cover the damage. However, because falling earth and rock are ultimately responsible for the damage to your home rather than the hurricane itself, these perils will not be covered by your standard homeowners insurance.
In cases where you do require protection, you should consider purchasing a Difference in Coverage (DIC) insurance policy, which acts as a gap coverage that fills in whatever is left uncovered after your homeowners insurance.
