The fees you pay to obtain your deck permits are used to pay for the inspector’s time to review the plans and make inspections throughout the project. Some permit fees for decks are based on the value of the project, others are based on the size of the deck, and yet, others are set fees. These fees can range anywhere from about fifty bucks to several hundred dollars depending on the scope of the project and the fee policy of the inspection department. You can call your building inspections division to find out how much they charge for deck permit fees. Include this cost into your project budget just like you would a joist hanger or a 2x10. You will find this is money well spent.
