Completely depends on your H.O.A. and/or municipality for where you plan on using the item. As a general rule of thumb, stand-alone BBQ grills and self-contained (propane) fire pits are typically viewed as temporary or removable items and do not require permits. (Some apartments, condos and townhouses do not allow BBQ grills/fire pits of any kind.) While built-in products, such as items with natural gas and electric leads are viewed as permanent and could require municipal approval.
