A crackling fire pit turns a backyard into an inviting retreat, but safety has to come first. Whether you are roasting marshmallows with the family or unwinding under the stars, a few straightforward precautions keep the experience enjoyable and hazard‑free. Our fire pits guide walks you through styles and setup, while this article focuses on the essential rules for placement, fuel, and supervision that every owner should know.
Placement and Clearance
Where you put a fire pit makes all the difference. The U.S. Fire Administration (USFA) states that chimineas, outdoor fireplaces, and fire pits must be used outdoors only and positioned at least 10 feet away from your home or anything that can burn. That includes siding, deck railings, overhanging branches, and stored firewood. A flat, non‑combustible surface such as stone or concrete is ideal.
If you are considering a fire pit on a deck, extra care is needed. The USFA’s clearance rule still applies, but decks introduce structural questions. A qualified builder or inspector can assess whether the deck can safely support the weight and heat, and your local building department can tell you about any code requirements. For more on deck construction and load considerations, see our decks section.
Permanent fire pit installations often involve digging for footings or a base. Before you break ground, call 811 a few business days ahead to have underground utilities marked. This free service helps you avoid hitting gas, electric, or water lines.
Supervision and General Safety
Once the fire is lit, attention is your best tool. The USFA emphasizes that you should closely watch children whenever the fire pit is in use. A metal screen over wood‑burning fires keeps sparks from floating out and landing on nearby surfaces. Make it a habit to turn off or fully extinguish the fire before you leave the backyard, and store matches and lighters out of children’s sight and reach.
The Environmental Protection Agency’s (EPA) Burn Wise program, which ran from 2009 to 2025 and remains a useful historic resource, also recommends keeping a fire extinguisher handy. Even a bucket of sand or a garden hose can serve as a backup if you stay alert.
Fuel: What to Burn and What to Avoid
What you put into the fire pit directly affects safety and air quality. According to the EPA’s archived Burn Wise guidance, you should burn only dry, split, well‑seasoned wood. Properly seasoned wood looks darker, weighs less, and sounds hollow when tapped against another piece. Season wood for at least six months, storing it outdoors, off the ground, with only the top covered. Covering the sides traps moisture, so leave them open for airflow. Wood burns best at a moisture content below 20 percent; you can check this with a wood moisture meter.
Start the fire with newspaper, dry kindling, or all‑natural fire starters. The EPA warns never to use gasoline, kerosene, or charcoal starter. These accelerants can create dangerous flare‑ups and release harmful fumes. Build a hot fire: for most appliances, a smoldering fire is neither safe nor efficient. Keep the doors of a wood‑burning appliance closed unless you are loading or stoking the live fire.
Many materials should never go into a fire pit. The EPA lists household trash, cardboard, plastics, foam, and colored ink from magazines or wrappers; coated, painted, or pressure‑treated wood; ocean driftwood, plywood, particle board, and any wood containing glue; and wet, rotted, diseased, or moldy wood. Burning these can release toxic chemicals and damage your appliance. If you use manufactured logs, check your appliance instructions first; choose only those made from 100 percent compressed sawdust. And to help prevent the spread of invasive forest pests, buy and burn locally cut firewood.
Ash Disposal
Ashes may look cool, but they can hide hot embers for hours. The EPA advises regularly removing ashes into a covered, metal container. Store that container outdoors on a nonflammable surface, well away from your home and any combustible materials. Never place ash containers on a wooden deck or near dry vegetation.
Local Rules, Burn Bans, and Air Quality
Before you light a fire, check with your local fire department or building department. Burn bans, permit requirements, and even noise ordinances vary from one community to the next. Homeowners associations may also have their own rules about fire pit use. The EPA also suggests checking your local air quality forecast before burning. On days when air quality is poor, skipping the fire helps protect everyone’s lungs.
Because regulations differ so widely, there is no single answer to what is allowed. Always verify the current rules where you live. A quick call or visit to your municipality’s website can save you from fines or a dangerous situation.
Carbon Monoxide Awareness
Carbon monoxide (CO) is an odorless, colorless gas that can cause sudden illness and death. The Centers for Disease Control and Prevention (CDC) explains that CO is produced whenever fuel burns, including in fire pits, grills, and fireplaces. While fire pits are designed for outdoor use, the CDC’s broader safety advice is clear: never burn anything in an enclosed space. The CDC gives a related example for generators: never run one inside a home or garage, even if doors and windows are open.
Protect your household by installing battery‑operated or battery‑backup CO detectors near every sleeping area. The CDC recommends checking detector batteries when you change your clocks each spring and fall, and replacing the entire detector according to the manufacturer’s instructions or every five years. A detector with a digital readout can show you the highest CO concentration in your home, adding an extra layer of awareness.
Putting It All Together: A Fire Pit Safety Checklist
Use this summary, drawn from the official sources above, each time you plan a fire:
- Place the fire pit at least 10 feet from your home and anything that can burn (USFA).
- Supervise children closely and use a metal spark screen (USFA).
- Burn only dry, seasoned wood with a moisture content below 20 percent (EPA).
- Start fires with newspaper, kindling, or natural starters, never gasoline or charcoal starter (EPA).
- Store ashes in a covered metal container on a nonflammable surface outdoors (EPA).
- Check local burn bans, permit rules, and air quality before lighting (EPA and local authorities).
- Install and maintain CO detectors in your home (CDC).

Frequently asked questions
How far should a fire pit be from a house?
The U.S. Fire Administration says fire pits should be at least 10 feet away from your home or anything that can burn. This applies to siding, deck railings, and overhanging branches as well.
Can I use a fire pit on a wooden deck?
The USFA does not specifically prohibit it, but the 10‑foot clearance rule still applies, and a deck is a combustible surface. If you choose to place one on a deck, consult a qualified builder to evaluate the deck’s load capacity and heat resistance, and check with your local building department for any code restrictions. Our decks page has more on deck construction and safety.
What should I do with ashes from my fire pit?
According to the EPA, you should regularly remove ashes into a covered, metal container and store it outdoors on a nonflammable surface, away from your home and any dry vegetation.
