Deck construction - do I need a building permit?
A building permit is required for construction of a deck. This deck permit application packet will provide you with the forms necessary to obtain a building permit for deck construction.
Inspections during the construction process are required. You will see a list of the required inspections on this link.
In some instances, repair of an existing deck may not require a building permit. It is suggested you contact the building inspector in the Building & Inspections Division ((618)624-4500 x 4) and discuss the work you are proposing to determine if a permit is required.
