The most basic policy recommended for any business is General Liability. It protects a business from claims of bodily injury or property damage to a third-party. For Architects, it is also recommended to add Errors and Omissions coverage to their insurance policy. Errors and Omissions Insurance, also known as Professional Liability Insurance, covers errors and omissions in your services to clients that lead to financial losses for them. If you own a lot of expensive property, also add Commercial Property Insurance to your policy to protect your contents and assets.
