October 15 is a hard line on the calendar for anyone planning to burn cleared brush in Tennessee. Up until that date, open burning within 500 feet of forest, grassland, or woodland requires no state permit at all outside the regulated season; the day it flips, a burn permit becomes mandatory for exactly the same fire. If you’ve been sitting on a debris pile waiting to strike a match, this is the countdown that actually matters, whether your property sits in Franklin, Columbia, or anywhere in between on this corridor.
What Changes on October 15
Tennessee’s burn-permit season runs October 15 through May 15 every year, administered by the Tennessee Division of Forestry. Inside that window, any open burning within 500 feet of forest, grassland, or woodland requires a permit, obtained free through BurnSafeTN.org or by phone to your county’s Division of Forestry office. Outside the window — roughly mid-May through mid-October — no state burn permit is required for the same fire, though local ordinances can still apply regardless of season.
The practical effect for landowners on this corridor: any debris pile from summer clearing that’s been waiting to burn now needs a permit before it can be lit, and that permit has to be current for the specific day you actually burn, not just the week you requested it.
Getting the Permit
The process itself is straightforward and free — BurnSafeTN.org issues permits online in minutes for most locations, checking current weather and fire-danger conditions before approving a burn for a given day. A permit approved for today doesn’t guarantee approval tomorrow if wind or drought conditions change; check again each day you actually plan to burn rather than assuming one approval covers an open-ended window through the whole season.
The Mount Pleasant Wrinkle
Most of this corridor follows the state system exactly as described above. Mount Pleasant is the one exception: burning within city limits requires its own approval from the city and the Mount Pleasant Fire Department, layered on top of the state permit, and it’s restricted to daylight hours — sunrise until one hour before sunset. If your property sits inside Mount Pleasant’s city limits specifically, budget for this extra step; the state permit alone isn’t sufficient there, and skipping it can mean a citation even with a valid state permit already in hand.
Burn Rules at a Glance
| Jurisdiction | Permit Required Oct 15–May 15 | Permit Required May 16–Oct 14 | Additional Local Layer |
|---|---|---|---|
| Unincorporated Williamson/Maury County | Yes, via BurnSafeTN.org | No state permit required | None beyond state rule |
| Franklin, Thompson’s Station, Spring Hill, Columbia | Yes, via BurnSafeTN.org | No state permit required | None currently beyond state rule; confirm with city if annexed recently |
| Mount Pleasant (city limits) | Yes, state permit plus city/fire department approval | City/fire department approval still required | Daylight hours only, sunrise to one hour before sunset |
Why Mulching Sidesteps This Entirely
None of this applies if debris never gets piled for burning in the first place. Forestry mulching grinds brush and cedar in place, leaving mulch on the ground rather than a pile waiting on a permit and the right weather day. For anyone clearing close to the October 15 line specifically, mulching removes the calendar dependency altogether — the work can proceed regardless of which side of the date you land on, without a single phone call to check conditions.
Planning Your Debris Method Around the Calendar
If you’re mid-project as the season changes, it’s worth a quick conversation with whoever’s clearing your property about which debris method actually fits your timeline. A pile that was going to be burned in early October under the old no-permit window may be simpler to haul or mulch than to hold for a permit once the season flips, particularly if your schedule doesn’t allow for checking daily burn-safe conditions. See Land Clearing Permits in Middle Tennessee for the fuller regulatory picture beyond just burning.
Why the Season Runs This Way
The October-to-May window isn’t arbitrary. It roughly tracks Tennessee’s dormant season for vegetation and the drier, more fire-prone stretch of fall and winter, when dead leaves and dried undergrowth carry a fire farther and faster than the greener growth of late spring and summer does. The Division of Forestry uses the permit system to track conditions day by day within that window rather than banning burning outright, since a calm, damp day in December can be perfectly safe to burn while a windy, dry day in the same month might not be safe at all.
What Happens If You Burn Without a Permit
Burning without a required permit during the regulated season is a citable offense, and more importantly, it removes the built-in safety check that the permit system provides — namely, confirmation that conditions are actually safe to burn on that specific day. Beyond the legal risk, an unpermitted burn that gets away from a debris pile is a liability problem that dwarfs whatever time the permit process would have taken. The five minutes it takes to check BurnSafeTN.org is cheap insurance against a genuinely expensive mistake, and it’s worth doing every single time you plan to burn, not just the first time.

Do I need a permit to burn brush right now, before October 15?
No — outside the October 15 to May 15 season, no state burn permit is required for the same fire, though local ordinances can still apply regardless of season.
Is the burn permit free?
Yes, permits through BurnSafeTN.org are free of charge.
Does a burn permit approved today work for tomorrow?
Not necessarily — approval depends on current weather and fire-danger conditions, so check again for each specific day you plan to burn.
Does Mount Pleasant follow the same rules as the rest of the corridor?
Mostly, but with one addition: burning inside Mount Pleasant city limits requires city and fire department approval on top of the state permit, and is limited to daylight hours.
