How Wisconsin's Burn Permit System Works
Wisconsin's fire season is concentrated in spring, when snowmelt exposes cured grass and deciduous leaf litter before green-up. The DNR's forestry division operates through county and area offices. For residential burning, a call to your county DNR forester gets you a permit number and current fire danger information. Northern Wisconsin's jack pine barrens and mixed forests have seen increasing fire activity as droughts become more frequent.

Frequently Asked Questions — Wisconsin
During the fire danger season (primarily spring), yes — a DNR permit is required. Contact your county DNR forestry office. Summer and fall burning may require permits during dry conditions. Local ordinances apply in urban areas.
Late fall (October–November) after leaf drop and first frosts, or early summer (June–July) when green-up has fully occurred and fire won't carry through grass. Avoid April–May when spring fire danger peaks.
