In simplest terms, a commercial property policy covers your stuff - large and small. From a physical building to desks, doors, computers, signs or a warehouse filled with inventory, businesses need this policy to protect themselves from the loss of these assets due to theft, fire, wind, hail, and vandalism.
In some cases, this policy is combined with Professional Liability Insurance, which covers businesses when a mistake is made. It offers protection from legal claims and lawsuits, up to the selected policy limits.
Coverage will depend on the type of business and what products or services one offers. But there are two main types of coverage achieved through this product: Malpractice (healthcare) and Errors and Omissions (for those who dispense advice or services).
