Releasing balloons in Tennessee is illegal once you go past 25 in a single day. Under Tennessee Code 68-101-108, each balloon over that limit is a separate civil violation carrying a $250 penalty, and the law applies to private citizens, businesses, and government employees alike.
The 25-Balloon Rule
The statute makes it unlawful to knowingly release more than 25 qualifying balloons into the atmosphere in one day. There is no shorter window written into the law. Whether the balloons go up all at once or in batches over the course of the day, the count is cumulative.
The word “knowingly” does real work. A balloon that slips from a child’s hand at a fair is not what the statute targets. A planned release at a wedding, funeral, memorial, or promotional event is.
Government actors get no pass. The statute specifies that “no person, including an officer or employee of this state or any political subdivision of the state” may exceed the limit. A city-sponsored ceremony faces the same rule as a backyard party.
Which Balloons Count Toward the Limit
Two conditions have to be met for a balloon to fall under the statute. It has to be made of a nonbiodegradable material, or a biodegradable material that takes more than several minutes of contact with air or water to break down. And it has to be filled with helium or another substance that makes it rise or float.
That sweeps in essentially every helium balloon sold at party supply stores. Latex balloons marketed as biodegradable have been shown to retain their shape and size for months in water and compost, well past the “several minutes” threshold in the statute. A “biodegradable” label on the package is not a safe harbor.
How the Penalty Adds Up
The violation is civil, not criminal. No jail, no misdemeanor on your record, no criminal court date. Just money.
The math is where it hurts. Each balloon released beyond 25 in a day is its own violation at $250. Release 50 balloons at a memorial and you are 25 over the limit, which is $6,250 in penalties. Release 100 at a corporate event and the exposure is $18,750. The $250 is not a cap on the day; it is the price of each extra balloon.
Exemptions
Weather Balloons
Weather balloons used to carry scientific instruments during experiments or testing procedures are exempt. That covers the radiosonde launches the National Weather Service and research institutions run to collect atmospheric data. A hobbyist launch qualifies only if it involves scientific instruments in a genuine experiment.
Certain Counties
Tennessee Code 68-101-108(d) exempts specific counties by referencing narrow population brackets from the 1980 federal census or any subsequent census. Tennessee frequently uses population brackets to single out counties without naming them. Whether your county is exempt depends on matching the current census figure against the brackets in the statute, so it is worth checking before a large release.
What the Law Does Not Reach
Balloons that never rise fall outside the statute. The law only applies to balloons filled with helium or another substance that causes them to rise or float. Air-filled balloons on sticks at a birthday party are not covered. Tethered or weighted helium balloons used as decorations are not “released” for purposes of the statute.
Hot air balloons are a separate category entirely. The FAA treats a hot air balloon as a piloted lighter-than-air aircraft under federal aviation rules, not something “released” into the sky.
Small-scale releases also fall below the line. Letting go of one balloon, or even a handful, does not cross the 25-balloon threshold. The statute is aimed at mass releases.
Local Ordinances May Go Further
Tennessee cities and counties can adopt their own rules. Some jurisdictions ban balloon releases outright, set a lower threshold, or fold releases into existing littering and environmental nuisance codes with their own penalties. For a public event, particularly one in a park or near a waterway, check with the city or county clerk before finalizing plans.
Alternatives That Avoid the Statute
The per-balloon structure makes a mass release an expensive risk for any organizer. Bubble releases, rice paper floating lanterns, flag or banner displays, and native plant seed releases sidestep the statute entirely. Some events use “balloon glow” setups where balloons stay tethered and lit rather than being released, keeping the visual without the legal exposure. For decorations, weighting or tying balloons keeps them out of the statute’s definition. A balloon tied to a chair and a balloon let go into the sky are, under Tennessee law, two very different things.
