Wisconsin DNR Fire Danger: Permits, Daily Rules, and Penalties

A Wisconsin DNR burn permit is free, issued annually to a person rather than a property, and available online, by phone at 1-888-WIS-BURN (947-2876), or in person at a DNR office or from an emergency fire warden.¹ Holding the permit is only half the job. Before you light anything, you have to check your county’s daily burn restrictions after 9 a.m. on the day of the burn, because fire conditions can shut down burning on short notice.

How to Get the Permit

You must be at least 18 to apply.² The online application takes an email address and issues the permit immediately. The phone line runs from 7 a.m. to 10 p.m. and will mail you one. You can also walk into a DNR office or get one from an emergency fire warden.¹

The permit stays with you, not your address. You can use it anywhere in the state where a DNR permit is required, but it is non-transferable. The person actually lighting the fire has to carry the permit and show it to law enforcement or firefighters on request.¹

Do You Actually Need One

Wisconsin splits the state into intensive and extensive forest protection areas. In intensive protection areas, you need a DNR burning permit for any outdoor fire other than a campfire used for warming or cooking, year-round, whenever the ground isn’t fully covered in snow. In extensive protection areas, the permit requirement runs January through May when the ground isn’t snow-covered, plus any other period the DNR extends by order.³

The DNR’s fire authority applies outside village and city limits.⁴ If you’re inside city or village limits, or in an area the DNR doesn’t cover, your town or county may still have its own burning ordinance. Check with the local clerk before burning.

Two boundaries worth knowing. A DNR permit does not cover burning on federal land. The Chequamegon-Nicolet National Forest runs under separate U.S. Forest Service rules, and unauthorized fires or burn-ban violations there carry federal penalties of up to $500, up to six months in jail, or both under 16 U.S.C. § 551.⁵ Contact the local ranger district for federal permit requirements. The permit also does not authorize campfires used strictly for warming or cooking, which fall outside the DNR’s permit requirement in the first place.

Checking Daily Restrictions Before You Burn

Having a permit does not mean you can burn today. After 9 a.m. on the day you plan to burn, check the current restrictions for the county where the fire will be.¹ You have two options:

The WisBURN mapping application. Select your county to see whether burning is allowed, what hours are permitted, and any size limitations.⁶
The 1-888-WIS-BURN (947-2876) recorded hotline for current conditions.²

If the daily check shows burning is prohibited, every permit in that county is suspended until conditions improve. When burning is allowed, it’s typically restricted to late afternoon or evening to avoid peak midday heat and wind.¹ A county that allows burning in the morning can be shut down by afternoon if wind picks up or humidity drops, so keep watching the weather while the fire is active and put it out if conditions worsen.⁷

What You Can Burn

The permit covers vegetative material: leaves, brush, pine needles.⁸ It does not cover household garbage, construction debris, or plastics. Burning those materials typically violates air quality rules enforced separately from the DNR’s fire regulations, so a green light on WisBURN still doesn’t let you put trash on a brush pile.

Safety Conditions Attached to the Permit

Every permit comes with conditions the holder has to follow:

Maintain a mineral soil firebreak around the burn area, with the surrounding ground clear of anything flammable.
Keep a water source and firefighting tools at the site.
Keep the fire small and manageable; the daily restrictions may set specific size limits.
Never leave the fire unattended.
Drown the fire, stir the ashes, and repeat until everything is cold. Come back later to check for lingering smoke or embers.

These are the permit terms.¹ Skipping any of them is where a legal burn becomes an illegal one.

What Happens If You Break the Rules

Wisconsin’s penalty structure under Wis. Stat. § 26.14 is tiered:

Failing to fully extinguish a fire, first offense: a forfeiture of up to $100.
Failing to fully extinguish a fire, subsequent offense: a fine of up to $500, up to 30 days in jail, or both.
Allowing a fire to escape and become a wildfire: a fine of up to $1,000, up to 90 days in jail, or both.
Intentionally setting fire to someone else’s land or a marsh: a Class H felony.⁹

The bigger exposure is civil. Anyone who causes a fire in violation of the fire statutes is liable to the state for the full cost of suppression and all damages to state lands, and liable to any municipality that helped fight the fire for the same.¹⁰ The DNR’s permit page states that if a fire escapes and starts a wildfire, the permit holder is responsible for all suppression costs and potentially any damages associated with that fire.¹

Suppression costs can include firefighter wages, heavy equipment, aircraft, and the overhead of coordinating the response. Bills reach into the thousands quickly on even a modest escaped fire and can climb much higher. A homeowner’s policy may not cover those costs when the fire resulted from negligence or an illegal burn. Getting the permit, running the daily check, meeting the safety conditions, and fully extinguishing the fire is the only reliable way to keep that liability off your name.
