Lenexa, KS Fire Regulations: Outdoor Burning (2026)

Section 3-5-D-1 bans open burning within the City of Lenexa unless it is permitted by and follows Article 3-5-D. The one carve-out covers burns or fires set for instruction and training under the direction and supervision of the Lenexa Fire Department. Section 3-5-I-4 defines open burning as igniting, burning or smoldering any material where combustion air contaminants go directly into the ambient air without passing through a stack or chimney, and it expressly includes burn barrels, metal drums and wire trash burners.

Section 3-5-D-2 sends permit applicants to the Lenexa Fire Department and vests the decision in the Fire Chief or designee in his or her sole discretion. The permit fee is set by ordinance or resolution and is nonrefundable. A residential burning permit covers land clearance materials from the permitted property, with a pile no larger than 8 feet in diameter and 6 feet high, kept at least 50 feet from any structure, vehicle or combustible material. Agricultural and commercial permits require 200 feet from any structure, a prescribed burn permit 25 feet, and a bonfire or ceremonial permit 50 feet unless the fire is in a noncombustible fire pit, with a pile no larger than 8 feet across. Agricultural, commercial and prescribed burns can also need approval from the Johnson County Environmental Department.

The burn ban authority sits in subsection F. When weather conditions warrant, the Fire Chief can temporarily suspend issuing open burning permits and can suspend permits already issued, and any permit is revocable at any time if the burn violates its terms or threatens public health, safety or welfare. Subsection D bars burning any man-made material, including refuse, plastics and lumber, and bars flammable liquids as an accelerant. Each site is inspected before a permit issues unless the Chief decides that is unnecessary. Under Section 3-5-D-4, owning or controlling the property where a burn occurred is prima facie evidence that you caused or allowed it, and the responsible person owes the City its costs for suppressing or abating the fire. Section 3-5-D-5 lets the Fire Chief inspect any property at any time and extinguish a burn without prior notice.
