Flooding is not covered by renters insurance. You must purchase a separate flood insurance policy. I bet the apartments have it for their property though. Renters Ins. covers: Fire or Lightening Windstorm or hail Explosion Riot or civil commotion Aircraft Vehicles Smoke Vandalism or malicious mischief Theft Volcanic eruption Falling objects Weight of ice, snow, sleet Accidental discharge or overflow of water or steam from within a plumbing, heating, airconditioning or automatic fire protective sprinkler system, or from within a household appliance. Sudden and accidental tearing apart, cracking,burning or bulging of a steam or hot water heating system, an air conditioning or automatic fire protective sprinkler system, or an appliance for heating water. Freezing of a plumbing, heating, air-conditioning or automatic fire protective sprinkler system or of a household appliance. Sudden and accidental damage from artificially generated electrical current.
