Do I need a ledger board on the house?

Hi All, we have just ripped out an old deck and are looking to build a new deck and extend down the side of the house. The old deck had a ledger board under the double doors, however we can't add a ledger board further down with the gas and water lines in the way. Do we need a ledger board or could we just add stumps concreted in just out from the house? What would you guys do?
