How Far Should a Fire Pit Be From a House?

So, how far should a fire pit be from a house? The International Fire Code (IFC), Section 307, sets 25 feet for a recreational fire and 15 feet for a portable outdoor fireplace, measured to any structure or combustible material. Many cities and counties adopt it, and many change it, so your own rules may be stricter or looser. This guide shows what the code says, how decks, fences and trees change the answer, and how to check what applies where you live. Pick the greater of the code distance and your fire pit manual's distance, and treat that as a minimum, not a target.

The Common Rules: 15 and 25 Feet

No single national law sets one number for every backyard. What most homeowners meet is the International Code Council's fire code, which local governments adopt and amend. West Metro Fire Rescue publishes its regulations taken from the 2015 edition of the IFC, Section 307 (Open Burning, Recreational Fires and Portable Outdoor Fireplaces), and the figures below come from that page.

Recreational Fires: 25 Feet

The IFC treats a recreational fire as an outdoor fire for pleasure or cooking, with a fuel area no larger than 3 feet across and 2 feet high. Under the text West Metro Fire Rescue publishes, that fire must stay 25 feet from a structure or combustible material, someone must watch it until it is out, and a fire extinguisher or another approved means such as a garden hose or water barrel must be within reach. A bigger fire needs an open burn permit.

Portable Outdoor Fireplaces: 15 Feet

A portable outdoor fireplace is the steel bowl, smokeless stove or gas fire table most of us put on a patio. The same page says it must be used per the manufacturer's instructions and kept 15 feet from a structure or combustible material, and it exempts one- and two-family dwellings, townhomes included, from that distance. Do not read the exemption as permission to light up against the siding. Your manual still sets limits, and your city may have deleted the exemption.

Why Manufacturer Manuals Come First

The code sets the legal floor for a generic fire pit. Your manual covers the model you actually bought, including overhead clearance, the surface it needs and the fuel it allows. Read it before you place the pit, and keep the shorter distance only if both the manual and your local rules allow it. If the two disagree, use the larger number.

Distances From Decks, Fences, Trees and Overhangs

The code wording is "structure or combustible material", which is wider than the house. Embers and radiant heat do not care whether the thing next to the fire is a wall or a fence. The practical answer is to apply the same distance to everything that can burn, then check with the people who enforce the code in your town.

Decks

A wood deck is both a structure and combustible material, so a fire pit does not belong on one unless the fire pit's manual says it can sit on a deck with a heat shield or stand. Even then, keep sparks off the boards and keep the pit well away from railings and the house wall. On a deck, a gas or propane unit with a listed clearance is usually the safer choice than a wood fire.

Fences and Sheds

Wood and vinyl fences, sheds and play sets are combustible in plain terms, and vinyl softens and warps under radiant heat well before it burns. Measure from the edge of the fire pit to the nearest panel, not from your seat. If your yard is narrow, a gas fire table or a smaller pit on a different part of the patio often solves what no distance chart can.

Trees, Hedges and Dry Grass

Branches above the pit matter more than trunks beside it, because rising heat and sparks reach them first. Keep the area above the flames clear and trim dead limbs. Dry grass, leaf litter and mulch should be cleared from around the pit, and during dry weather or wind many towns restrict or ban fires altogether.

Overhangs, Pergolas and Covered Patios

Eaves, pergolas and roofs trap heat and smoke, and they are combustible material overhead. Our guide on whether a fire pit can go under a covered patio goes through when that is acceptable. For how much room the seating needs around the flames, see how big a patio should be for a fire pit.

Wood vs Gas Fire Pits

Wood-Burning Pits

Wood throws sparks and embers, so it faces the strictest reading of the rules. A mesh spark screen helps, but it does not replace distance. Smokeless wood stoves burn cleaner, yet they still get very hot on the outside and still shed sparks when you load them, so treat them as wood fires.

Gas and Propane Pits

Certified gas fire pits come with clearances in their installation manual, which cover distance to walls, overhead structures and the ground. They make no sparks, can be shut off in a second and are often allowed where wood fires are banned, which is why they suit tight yards. Their clearances are still a rule, not a suggestion, so follow the printed figure. Browse our propane and gas fire pit reviews if that fits your space.

Which Is Easier to Place Legally?

Gas is easier to place close to a house, because the manual gives you a defined clearance and local rules are usually friendlier to it. Wood needs the biggest buffer and the most paperwork. Check the local rule first, since some places regulate every kind of open flame the same way.

Local Codes, HOAs and Burn Bans

Adoption of the IFC varies. West Metro Fire Rescue publishes its own rules, other fire districts change the text, and some delete parts of it. A distance you read in a blog post, including this one, is a starting point. Your local authority has the final word.

How to Check Your Rules in 15 Minutes

• Search your city or county name plus "open burning" or "recreational fire" on the official site.
• Call the non-emergency number of your fire department and ask for the rule on portable fire pits in a residential yard.
• Ask whether wood and gas pits are treated differently, and whether a permit is needed.
• Write down the answer, the date and the name of the person who gave it.

HOA and Lease Rules

Homeowners associations and landlords can ban open fires or limit them to gas on top of whatever the city allows. Read your covenants or lease, and ask in writing if the wording is vague.

Burn Bans and Red Flag Days

Counties and fire districts issue burn bans during dry or windy spells. A ban can apply to wood and charcoal fires and sometimes to gas ones. Check your fire district's website or hotline on the day you plan to light up, and never burn in strong wind even when no ban is posted.

What to Put Under a Fire Pit

People also ask what the best surface to put a fire pit on is. Use a stable, level, noncombustible surface: concrete, pavers, stone, brick or compacted gravel. Grass, wood decking, composite decking and vinyl are poor choices, because heat and embers damage or ignite them. Always check what your manual says about the surface.

Pavers, Concrete and Gravel

Pavers and poured concrete are flat and fireproof, but sudden heat can crack some pavers, concrete and thin natural stone over time. A bed of compacted gravel under a ring of fire-rated brick or stone is a common, forgiving base.

Lawns and Decks

If a deck or lawn is your only flat spot, use a fire pit mat or a stand made for the job, and check that the manual allows it. A mat protects the surface from heat and falling embers, though it does not replace distance from the house.

Does a Fire Pit Raise Your Insurance?

It depends on the insurer. An open flame adds fire and liability risk, and an unpermitted or illegal pit may cause trouble if a claim comes up. Ask your agent or insurer directly whether a fire pit changes your premium or conditions, and whether they need to be told about it. Write the answer down.
