Clay County, MO Fire Regulations: Brush Clearance (2026)

045 sets statewide open burning standards but layers extra conditions onto the Kansas City, Springfield, St. Joseph, and St. Louis metropolitan areas under subsection (3). The general provisions bar burning tires, petroleum-based products, trade waste, construction or demolition debris, salvage waste, or asbestos-containing material by open flame, and bar any open burning that creates a public health hazard, a nuisance, a traffic hazard, or otherwise violates another rule or statute. Subsection (3)(A) lists the burning types the department allows when no other law forbids them, including recreational fires, food preparation fires, and household refuse burning, each carrying its own metro-area exception.

Yard waste is item 5, and clause A singles out the Kansas City metropolitan area: the open burning of trees, tree leaves, brush, or any other type of vegetation shall require an open burning permit. That single sentence reaches every unincorporated Clay County property, since the county sits inside the Kansas City metro boundary the rule references, unlike the milder St. Louis metro rule in clause D, which allows unpermitted brush burning between September 16 and April 14 in a plot no larger than 16 square feet.

Related subsection (3)(B)(2) requires the same director-issued permit for commercial land-clearing operations burning tree trunks, limbs, or vegetation anywhere in the Kansas City metro area or within 200 yards of an occupied structure, and subsection (3)(A)(4) bars unpermitted land-clearing burns inside the metro area altogether, pushing that activity to the permit track in subsection (3)(B). Permits are issued by the Missouri Department of Natural Resources' Air Pollution Control Program director, who under subsection (3)(E) may deny, revoke, or suspend any permit in a designated nonattainment area whenever conditions would harm air quality standards.

Untreated wood is separately defined in subsection (2)(A) as lumber and wood products that have not been chemically treated or manufactured with adhesives, resins, paint, or finish, a distinction that matters because untreated wood waste from qualifying operations can sometimes burn without a permit under different provisions that do not apply inside this metro area.
