We are under the 2015 ICC codes. There is a new trend in our jurisdiction where RV's parks are erecting covers over each individual RV spot where the tenant lives. The covers measure approximately 20' x 35' and open on all sides. Tenants are parking vehicles, building storage sheds and decks under the covers. My first question is what is the occupancy classification is this type of structure, Group S-2 Open Parking Garage or Group U Carport. Next Question is should there be a minimum fire separation distance and/or required firewall separating each RV cover?
