How Far Should a Fire Pit Be From the House?

The Number Fire Agencies Give

The U.S. Fire Administration's outdoor fire guidance gives one figure for backyard fire features: use chimneys, outdoor fireplaces and fire pits outdoors, at least 10 feet away from your home or anything that can burn. That is the distance most homeowners are looking for, and it is the one to plan around.

Florida's building code does not set a separate distance for a portable backyard fire pit in the chapter on chimneys and fireplaces, and a city or county may add its own. So 10 feet is the working minimum, and local rules or the pit maker's instructions can make it larger, never smaller.

Distance by Type of Fire

The fuel and the kind of fire change the number. Here is what each source says, side by side:

• Wood-burning fire pit, chiminea or outdoor fireplace: at least 10 feet from the home or anything that can burn (U.S. Fire Administration).
• Open campfire built on the ground: at least 25 feet from tents, shrubs and anything that can burn (U.S. Fire Administration); the Smokey Bear guidance says at least 15 feet from tents, vegetation and low branches, with overhead clearance of three times the flame height.
• Gas or propane fire pit: the clearances printed in that unit's installation instructions; no general figure applies.
• Yard waste pile: 25 feet from woods, brush or any combustible structure, 50 feet from a paved public road and 150 feet from other people's occupied buildings (Florida rule 62-256.700(1)).

What Counts as the House

The 10 feet is measured to the closest part of the house that can catch, which is rarely the block wall. Often the nearest points are overhead or attached, and each one moves the measuring point outward.

• Roof overhangs and soffits: measure to the edge of the eave above, not to the wall below it.
• Screen enclosures and lanais: the frame, screen and any roof panels are attached to the house, so measure to the outside of the enclosure, and never run a wood fire inside one.
• Pergolas, porch roofs and awnings: wood and fabric burn, and they sit right where heat rises.
• Wood or vinyl fences and gates: anything that can burn, so 10 feet from them as well.
• Sheds, play sets, firewood stacks and parked equipment: same rule.

Trees, Palms and What Hangs Overhead

Distance is not only sideways. Heat and sparks go up, which is why the Smokey Bear guidance asks for overhead clearance of at least three times the height of the flames and keeps fires away from low-hanging branches. A fire pit 12 feet from the house but under an oak limb or a palm crown is in the wrong place.

Dead palm fronds are the overhead fuel to watch most. They can hang dry on the tree long before they drop, and they sit exactly where a spark lands. If a palm leans over the patio, trim it or move the pit.

Measuring It Yourself

A tape measure and five minutes settle the question. Work from the outer rim of the pit, since that is where the fire's edge is, and check every direction, including up.

• Measure from the rim to the nearest eave edge, not the wall.
• Measure to the outside of any screen enclosure or lanai frame.
• Measure to fences, sheds, wood piles and decks.
• Look straight up for branches, fronds, wires and roof edges.
• Note which way the evening breeze usually blows smoke, and keep the pit downwind of windows and doors.

When the Yard Is Too Small for 10 Feet

Plenty of yards cannot fit a full 10-foot circle of clear space between the house, the lanai, the fence and the neighbor's shed. When the tape measure says no, the answer is not to split the difference. Options that keep to the guidance are a smaller fire somewhere else in the yard that does meet the distance, a gas unit whose own instructions allow the space you have, or no wood fire at that house.

The pull to put the pit close to the house is understandable, because that is where the chairs, the lights and the outlet are. Sparks and radiant heat do not care about convenience. A pit moved 10 feet out into the yard with a string of lights over it is a better evening than a pit that scorches the soffit.

When the Fire Feature Is Built Against the House

Masonry outdoor fireplaces are sometimes built close to a home or under a covered patio, with a chimney carrying the smoke up. Those are a different case from a fire pit, because the chimney has to clear the roof; outdoor fireplace against house covers that build in detail. Florida Building Code section R1003.9 asks that a chimney extend at least 2 feet higher than any part of a building within 10 feet and at least 3 feet above the point where it passes through a roof. A patio fireplace with a short chimney under a second-story eave fails that test and tends to smoke, which our guide on outdoor fireplace smoke problems covers.

If you have a built-in fireplace or fire pit near the house and are not sure it is safe where it sits, our outdoor fireplace service starts with a look at clearances, the fire box and the chimney.
