It's nice a new restaurant just opened yesterday in your building. It is a very nice looking restaurant and you went to eat there for breakfast it's cheap and very good. Wow, you feel so happy, but is it good for the premieum of your property damage insurance, Unfortunatly, no ! Why, because it is a higher risk for your insurance company. A Reastaurant has many equipments which are likely to cause a lot of damage, fire etc.
So,it might raise your damage property insurance premiums but it is better to tell your insurer about that,because if you don't they might not pay you in case of fire or other damages caused by your new neighbor, the restaurant.
