Ten feet looks farther than it is. Once a fire pit is burning properly, radiant heat reaches across that gap fast, which is why the clearance number and the surface underneath matter more than the pit’s shape or finish. Get those two things right and the rest of this build is straightforward work.
The setup below covers picking the spot, prepping the base, assembling the pit, and running fires that stay controllable from first flame to cold ash.
Pick A Spot That Satisfies Your Local Fire Code
Choose a level, open outdoor spot at least 10 feet from anything that can burn — siding, deck rails, fences, tents, grass, rooflines, and overhanging branches included.
Your city, county, or HOA fire ordinance overrides general guidance every time, and permits may be required. One phone call to the local fire department’s non-emergency line settles it in minutes.
Burn bans and air-quality alerts can also shut down an otherwise compliant pit, so it is worth knowing how your area posts those notices before you build anything permanent.
Prep A Noncombustible Base Before Anything Else
Wood-burning fire pits belong on level, noncombustible ground — patio blocks, brick, concrete, or a purpose-built stone surround. Setting one directly on a wooden deck is a serious hazard, and one municipal source allows a portable pit on a deck only when it sits on brick or stone, never on bare wood.
Clear the whole area of trip hazards and anything combustible, and push seating back a safe distance rather than right up against the rim. If you are choosing a unit, our tested roundup of the best backyard wood fire pit picks covers which designs handle regular burns well.
Keep a water hose, a bucket of water, or a fire extinguisher within reach before the first fire, not after the first scare.
Use Seasoned Hardwood And Gear That Keeps Embers Contained
Burn only clean, dry, seasoned hardwood — never green or wet wood, construction scraps, plastic, garbage, or yard waste. Wet wood smokes heavily and throws more sparks; treated lumber and plastics release fumes you do not want near a gathering.
A spark screen or mesh guard belongs on the pit for every wood-burning fire, and some local codes require a spark arrestor with small mesh openings. Keep flames modest rather than dramatic — oversized fires are harder to control and easier to spread.
| Safety Check | Standard Practice | When To Raise It |
|---|---|---|
| Clearance from combustibles | At least 10 feet | Local code requires 15 feet |
| Base surface | Patio blocks, brick, or concrete | Deck use needs a fire-rated base |
| Fuel type | Clean, dry, seasoned hardwood | Never green wood or treated scrap |
| Spark containment | Spark screen on every fire | Spark arrestor where required |
| Burn bowl size | Keep fires reasonable | Some codes cap 36 in. wide, 24 in. tall |
| Buffer for kids and pets | 3 feet minimum | Wider when kids are running |
| Ash disposal | Metal container with a tight lid | Hot ash has started house fires |
| Extinguishing gear | Hose, bucket, or extinguisher nearby | Dry, windy days |
Burn, Watch, And Shut Down Properly
Start with a small fire, add split seasoned wood a piece at a time, and keep the flame under control rather than piling fuel high. Sitting close enough to roast marshmallows is fine; leaving the pit to grab something inside is not.
When you are done for the night, douse the fire thoroughly, stir the ashes, and douse again until nothing is warm. Let the ashes cool completely, then move them into a metal container with a tight-fitting lid kept well away from anything combustible. The US EPA’s Burn Wise program treats clean-burning practices as a smoke-reduction tool, and the same habits cut your ember risk.
Smoke drifting toward a neighbor’s window or a nearby road is a sign to reposition the pit or call it a night — nuisance ordinances get enforced even when safety rules are met.
FAQs
Can I put a wood-burning fire pit on my wooden deck?
Not directly on the wood. One municipal source allows a portable pit on a deck only when it sits on brick or stone, and only where local rules or the manufacturer’s instructions permit it. Siding, rails, and deck boards burn, so an unrated pit on bare wood is a hazard worth avoiding entirely.
How far should a fire pit be from my house?
Some local codes require 15 feet. Measure from the burn bowl’s edge, not the center, and check your city or county fire ordinance before building.
What wood should I burn in a backyard fire pit?
Clean, dry, seasoned hardwood only. Green or wet wood smokes heavily and throws more sparks, while construction scraps, plastic, garbage, and yard waste release fumes and burn unpredictably. Seasoned hardwood splits burn hotter and cleaner with less smoke.
