| General Guidelines for Fire Department Access Roads |
The AHJ (Fire Marshal Division) shall have the authority to designate public or private fire lanes and fire department access roads as considered necessary. NFPA 1: 18.2.3. Fire department access roads shall be provided such that any portion of the facility or any portion of an exterior wall of the first story of the building is located not more than 150 feet from fire department access roads as measured by an approved route around the exterior of the building or facility. (Radial measurements are not permitted.) NFPA 1: 18.2.3.2.2 When measured from either end this measurement effectively allows 300' of most structures to not have formal fire department access. |
