Full Breakdown

, provided a detailed list of conditions is met. Burning cannot occur less than 25 feet from any building, structure, shed, garage, tree, shrub, bush, fence or other combustible material. The fire itself must be contained in a below-ground fire pit built at least 4 inches deep and no more than 3 feet in diameter, ringed with noncombustible material like concrete, rock or cement block, or in a commercially manufactured noncombustible Outdoor Fireplace placed on a noncombustible surface. Burning is banned outright whenever wind speed exceeds 10 miles per hour, and flame height can never exceed 3 feet measured from the base of the fire.

Only clean burning material qualifies: rubbish, garbage, recyclables, trash, yard waste, green wood, pressure-treated lumber, and anything coated with rubber, plastic, leather, petroleum products or containing flammable or combustible liquids are all barred from the pit. Whoever is burning must keep adequate suppression equipment on hand, such as shovels, a 4A-rated or larger fire extinguisher, or a hose, and a person at least 18 years old must attend the fire at all times it burns. A Fire Inspector, Police Officer or other City agent can order the fire out if it endangers health, safety or nearby property, and the Fire Department may escalate under Wis. 14 if the responsible party does not immediately comply.

Violations & Fines

Burning outside the permitted hours, closer than 25 feet to combustibles, in an oversized or unlined pit, during high wind, with prohibited materials, or without an adult attendant violates § 21.04 and is punishable under § 21.11: a forfeiture of $25 to $500 per violation plus prosecution costs, with each day of a continuing violation counted separately.
