Fire Setback Enforced
1
Setback Notes

Fire setback pathways must go around large obstructions like chimneys or skylights and still allow for the full width of the pathway.


The AHJ does not grandfather/exclude existing systems from the >33% 3ft setback on each side of ridge rule. If new+existing array coverage is greater than 33%, and the existing system is not 3ft away from the ridge, the new system must be downsized to stay below the 33% array coverage. If that is not possible, provide holding options.
