In most places, yes — you can have a bonfire in your backyard, but only a small one, and only if you follow your local fire code. What most people call a bonfire is technically a “recreational fire” under the International Fire Code: a small outdoor fire no more than three feet across and two feet tall. Stay within that size and meet the setback and safety rules, and you usually don’t need a permit. Go bigger, and you’re in true bonfire territory, which almost always requires permission from your fire department first.
Recreational Fire or Bonfire
The size of the fire decides which set of rules applies. Under the International Fire Code, a recreational fire has a fuel area no larger than three feet in diameter and two feet in height. Anything larger is a bonfire, and bonfires trigger stricter requirements, including a minimum 50-foot setback from any structure and, in most jurisdictions, a permit from the local fire authority.
A modest fire pit with a few logs falls under recreational fire rules. A large fire built for a party or celebration does not, and lighting one without talking to your fire department first is a fast way to draw a code enforcement visit.
What Your Local Fire Code Likely Requires
Fire regulations are overwhelmingly local. Cities and counties build on the International Fire Code and often layer on their own restrictions, so rules can change block to block between neighboring towns. A few requirements show up almost everywhere:
- A setback of at least 25 feet between the fire and any structure or combustible material, with nothing flammable in between.1UpCodes. 307.4.2 Recreational Fires
- Burning hours. Some areas restrict fires to daylight or cut them off around 10:00 PM.
- Permits, even for small recreational fires in some jurisdictions. Fees run roughly $5 to $70 where they apply.
- Containment inside a non-combustible fire pit, fire ring, or chiminea.
Your local fire department or code enforcement office is the only reliable source for the rules at your address. Don’t assume that what’s legal in one city applies in the next one over.
Check for a Burn Ban Before You Light
Even when your city normally allows recreational fires, a temporary restriction can shut you down on any given day.
Burn Bans
State or county authorities issue burn bans during drought, high winds, or elevated wildfire risk. An active ban overrides your local ordinance — any open burning becomes illegal for the duration, regardless of what your city code normally permits. Bans can appear with little notice, so check your state forestry division or local fire department’s website the day of the fire. Violating a ban carries harsher penalties than a routine code violation because authorities treat it as a deliberate act during a known emergency.
No-Burn Days
State environmental agencies also declare no-burn days when air quality drops or atmospheric conditions trap pollutants near ground level. These alerts can cover outdoor recreational fires along with wood stoves. In jurisdictions that enforce them, lighting a fire on a declared no-burn day is a finable offense.
What You Can Burn
Clean, dry, untreated firewood is what virtually every jurisdiction allows. Seasoned hardwood burns more predictably and produces less smoke than green or softwood.
Materials almost universally prohibited:
- Household trash and plastics
- Rubber, tires, and petroleum-based products
- Treated, painted, or stained wood, and construction debris
- Yard waste like leaves, grass clippings, and brush, especially in urban and suburban areas
These give off toxic fumes and heavy particulate matter. Burning trash is illegal statewide in many states regardless of whether your local code mentions it separately.
Safety Rules While It’s Burning
Someone Has to Stay With It
The International Fire Code requires a recreational fire to be constantly attended by a responsible person from ignition until it’s completely out. Stepping inside for 20 minutes while the fire burns down is a code violation in most jurisdictions. The attending person must also have extinguishing equipment ready for immediate use: at least one portable fire extinguisher with a minimum 4-A rating, or an alternative like a connected garden hose, a water barrel, or a supply of dirt or sand.2UpCodes. Open Burning, Recreational Fires and Portable Outdoor Fireplaces
Wind and Weather
Open burning is prohibited when conditions make a fire hazardous. In practice, that rules out windy days. Many local codes set a specific wind-speed threshold, often 10 to 15 mph. Even without one, a fire official who decides your fire is dangerous can order you to put it out on the spot.
Look Up, Not Just Around
Horizontal setback isn’t the only clearance that matters. Fire safety guidelines call for at least 21 feet of vertical clearance above the fire pit. Overhanging branches, covered patios, pergolas, and low rooflines are all hazards. Place the pit on level, non-combustible ground, and never under any overhead structure.
Putting It Out and Handling Ashes
Embers hold enough heat to reignite for days after a fire looks dead. Let the fire burn down to ash, then drown it with water while stirring to expose hidden hot spots. Keep stirring and adding water until everything is cool to the touch.
Move cooled ashes into a metal container and keep that container at least 10 feet from your house, garage, deck, or anything flammable. Leave them there for several days before discarding. Never dump ashes into a plastic trash can, cardboard box, or paper bag. Fire departments respond to trash fires started by “cold” ashes more often than you’d expect.
HOA Rules and Lease Clauses Can Override the Code
Meeting the fire code doesn’t mean you’re in the clear. HOA covenants frequently prohibit open fires outright or limit them to specific pit types, locations, or hours. Fines typically start at $50 to $200 per violation and climb with repeat offenses. Some HOAs ban recreational fires entirely, and no amount of code compliance changes that.
Renters face the same problem from a different direction. Lease agreements often restrict or forbid open flames, usually because of the landlord’s insurance. Violating that clause can bring anything from a written warning to eviction, plus responsibility for any damage. Read the lease before assuming a backyard fire pit is fine because the property has a yard.
What Happens If You Break the Rules
The consequences of an illegal backyard fire stack, and they’re not limited to a single ticket.
Code Enforcement Fines
The most common penalty is a fine from local code enforcement or the fire department. First offenses typically run from a few hundred dollars up to $500, though amounts vary by jurisdiction. Burning during a ban or burning prohibited materials pushes fines higher, sometimes past $1,000. Repeat offenders face escalating penalties and possible misdemeanor charges.
Criminal Charges
When a fire actually threatens life or substantial property, the situation moves beyond a municipal fine. Starting a fire that endangers others can be charged as reckless burning, prosecuted as a misdemeanor or a felony depending on the state and the outcome. The dividing line is usually whether the fire caused serious property damage or physical harm. Failing to control a fire you started legally can also lead to criminal charges if it escalates.
Civil Liability
If your fire escapes and damages a neighbor’s property, you can be sued for the full cost of repairs, replacement, medical expenses, and other losses caused by the fire. Having violated the fire code at the time makes a “not negligent” defense extremely hard to make. Damages can run into tens of thousands of dollars for even modest property loss.
Fire Department Cost Recovery
This one catches people off guard. Fire departments in many jurisdictions can bill the responsible party for the cost of responding to an illegal fire, covering labor and equipment at rates that commonly run $400 to $500 per hour per apparatus.3USFA. Cost Recovery for Non-EMS Incidents Two engines for three hours puts you into the thousands before any fine or lawsuit.
Insurance Denial
Standard homeowners policies generally exclude coverage for damage tied to illegal activity. If your fire violated a local ordinance or was set during a burn ban, the insurer can deny the claim for damage to your own property, leaving you personally responsible for repairs to both your property and your neighbor’s.
