Fire Clearances for R-3 Roofs: Minimum 18” at ridge lines with loading on opposite slope (0” clearance if no panels on opposite slope); 18” at hips and valleys (0” clearance if no panels on opposite slope), 3’ at gables and rakes (must have at least two (2) three-foot (3’) pathways on opposite ends of single-ridge roofs); 0” clearance at soffits. 02/05/20 - Above clearances are NOT confirmed with the AHJ. Per Plan Checker Jayce, the AHJ follows IRC 2015 for fire clearances. When I read him the above data, he did not recognize the verbage and stated that the City prefers more restrictive fire clearances in the 2015 code. Recommend layouts follow standard IRC 2015 setbacks and clearances until confirmed. [JAM]
