Can you burn cleared brush in Williamson County, TN?
Legally? Sometimes, in some places, inside a season, with a permit, and only certain material. Practically? Around Franklin and Brentwood the honest answer is usually no, and the rules are stacked so heavily against burn piles that most of our clearing customers choose forestry mulching or haul-off and never light a match. Here is what the state, TDEC and both cities actually say.
The state layer: a season and a 500-foot rule
Tennessee’s Division of Forestry requires a burn permit for debris burning from October 15 through May 15. The underlying statute makes it unlawful to start an open-air fire in that window within 500 feet of any forest, grassland or woodland without one, which in this county describes nearly every property. The permit itself is free: online at BurnSafeTN.org for leaf and brush piles, and by phone at 877-350-2876 for larger land-clearing and forestry burning, weekdays only. Permits are issued a day at a time, only when conditions are safe, and someone must stay with the fire until it is dead out.
The penalties escalate fast. No permit is a Class C misdemeanor. Burning during a declared burn ban becomes reckless burning, a Class A misdemeanor with fines up to $2,500. And state law makes whoever starts a fire civilly liable for the suppression costs if crews have to come put it out.
The city layer: Franklin bans it, Brentwood gates it
Franklin does not do brush burning, full stop. The fire department’s guidance reads: burning brush and trash is prohibited in Franklin. Yard waste goes to city collection. The single exception is construction burning under a Fire Marshal permit, and that path requires an air curtain destructor, industrial machinery that contains the smoke, on site.
Brentwood issues its own burn permits through the fire department, and the categories tell you who they were written for. Land clearing for development: 20 acres minimum, 500 feet from any occupied building or road, on-site native vegetation only, air curtain destructor required. Property cleanup: 3 acres minimum and 300 feet of clearance. A normal Brentwood lot qualifies for neither, which means the brush from clearing a Brentwood back acre has exactly two lawful exits: ground in place or hauled away.
Fairview prohibits outdoor burning entirely, and in the unincorporated county the state season-permit system is the governing layer.
The TDEC layer: only your own vegetation
Even with a permit in hand, TDEC’s open-burning rules control what goes in the pile. The exception that land-clearing burns ride on covers fires consisting solely of vegetation grown on the property of the burn site. Nothing hauled in, no lumber, no shingles, no plastics, no tires, and the department’s broader no-burn list adds household trash, construction debris and treated wood. Burning wood waste within 200 feet of an occupied building carries its own statutory conditions: constant attendance, 48 hours maximum, no more than twice in 30 days, and written permission from the neighbor inside 100 feet. TDEC warns improper burning can draw fines up to $25,000.
Why mulching makes the whole question disappear
Every rule above regulates one thing: fire. Forestry mulching grinds standing brush, cedar and privet into a chip layer right where it grew, so there is no pile, no smoke, no season, no setback math, no neighbor permission slip and no permit clock. The chips stay as ground cover and feed the soil, and on the properties where material does need to leave, our own dump trucks handle the haul-off side of a clearing job instead of a burn pile handling it badly.
One honest caveat: skipping the burn does not skip the dirt rules. Clearing at development scale still lives under the land disturbance permits we covered in our Williamson County clearing permit guide, so read that one alongside this.
