Do you need a permit for Deck Construction in Coconino County?
In Arizona, a Deck Construction requires a building permit.
A permit is required to build a deck in Coconino County. In the mapped WUI ignition zones the deck must use ignition-resistant or non-combustible materials: high-risk zones require a Class A non-combustible substructure (commonly steel framing), ignition-resistant decking such as PVC, and ember-resistant details, with the last few feet of any attached fence non-combustible. Coconino County (Flagstaff) enforces an adopted wildland-urban interface code in its mapped fire zones. Plans are reviewed under the Coconino County WUI code (AZ) code (IRC IWUIC); apply through Coconino County Community Development before work begins.
