Fire setbacks

Fire Setback Enforced

Setback Notes

Fire setbacks can be shown to be on either side of valleys and hips or divided onto both. Additionally, any layout change requires resubmitted plans to the AHJ, especially if they will change our fire setback locations. For photovoltaic arrays occupying not more than 33 percent of the plan view total roof area, not less than an 18โ€ clear setback is required on both sides of a horizontal ridge.
