Fire Pit Clearances: How Far From the House, Deck and Overhang

Steel fire pit burning on a gravel area well clear of a house, deck and overhanging trees

Short answer: the International Fire Code, which most US jurisdictions adopt in some form, sets two baseline distances. Recreational fires must not be conducted within 25 feet of a structure or combustible material (IFC 307.4.2). Portable outdoor fireplaces must not be operated within 15 feet of a structure or combustible material, and must be used per the manufacturer instructions (IFC 307.4.3). Your local fire code, municipal ordinance, HOA rules and — above all — the manual that came with your fire pit take precedence over any general figure, including these.

This is general information about published clearance distances, not a safety guarantee and not a substitute for your local fire authority or your manufacturer manual. Check your municipality before your first fire; many require a permit, and many issue seasonal burn bans.

The distances, and where they come from

What it is Baseline horizontal clearance Source
Recreational fire (open wood fire, fire ring, in-ground pit) 25 ft from any structure or combustible material IFC 307.4.2
Portable outdoor fireplace (chiminea, freestanding wood pit, some steel bowls) 15 ft from any structure or combustible material IFC 307.4.3, plus manufacturer instructions
Gas fire pit or fire table Per the manufacturer listing and the appliance manual The appliance listing governs; there is no single universal figure
Overhead clearance Nothing combustible above — no branches, awnings, umbrellas, pergola slats, eaves or roof Manufacturer manuals; overhead clearance is stated per model
Property line and structures on adjacent lots Set by local ordinance Municipal code

Some jurisdictions amend these figures, in both directions, and some add conditions such as a maximum pile size, an attended-at-all-times requirement, a wind-speed limit or a permit. Adoption is local, so the only reliable answer to "how far" is the one your fire department gives you.

The things people forget to measure from

  • The overhang, not the wall. Measure from the nearest combustible point, which is usually an eave, a soffit or a gutter, not the foundation.
  • Fences and sheds. A wood fence is combustible material. So is a plastic shed, a vinyl fence and a stack of firewood.
  • Trees and shrubs, including what is above. Overhead branches are the clearance most often missed, and dry evergreen foliage is the worst case.
  • Deck rails and furniture. Cushions, umbrellas, market umbrellas left open, and polypropylene rugs all count.
  • What is under the fire pit. Composite and wood decking, artificial grass and asphalt all deform or ignite under sustained radiant heat.

Deck and surface protection

If your manufacturer permits deck use at all — and many wood-burning pits do not — the pit still needs a heat barrier beneath it. Radiant heat from the base plus falling embers is what damages decking, and neither is stopped by a paving slab laid directly on the boards.

Surface Wood-burning pit Gas fire table Protection
Wood deck Usually not permitted — check the manual Often permitted if the model is listed for it Rated fire pit mat or pad plus an air gap under the pit
Composite deck Usually not permitted Check the manual and the decking maker guidance Rated mat; composite deforms at lower temperatures than wood
Concrete or paver patio Generally acceptable Generally acceptable A mat still prevents spalling and scorch marks
Artificial grass No No Melts from radiant heat alone
Bare soil or gravel Generally acceptable Generally acceptable Clear vegetation to bare mineral soil around the pit
Outdoor rug No No Remove it; synthetic rugs melt and carry flame

A screen or spark guard is the other half of this. It does not replace clearance, but it substantially reduces the ember travel that clearance exists to manage.

Why we do not stock alcohol-fuel tabletop fire pits

Pourable liquid and gel alcohol fuels have a long-documented failure mode: a flame that is burning invisibly in daylight, then refuelled, and the vapour above the container ignites and throws burning fuel outward. The US Consumer Product Safety Commission has repeatedly warned about pourable gel fuel and tabletop ethanol burners, and there have been recalls in this category. We have chosen not to carry pourable-fuel tabletop fire pits. If you already own one, follow the manufacturer instructions exactly and never add fuel to a burner that has been lit — let it cool completely first.

A pre-fire checklist

  1. Check your municipality for permits, burn bans and any local distance amendment.
  2. Read your fire pit manual and note the clearances it states for your model.
  3. Measure to the nearest combustible point, including overhead.
  4. Check the wind. Most local rules prohibit burning on windy days and it is the main driver of ember spread.
  5. Have a means of extinguishment within reach — a hose or an extinguisher, not a bucket you have to go and fill.
  6. Never leave a fire unattended, and fully extinguish before going inside.
  7. Dispose of ash only when cold, and never into a plastic or combustible container.

Quick answers

Can I put a fire pit on my deck? Only if the manufacturer lists it for deck use, your local rules permit it, and you use a rated protective mat. Many wood-burning pits are ground-use only.

How far from the house is enough? Start from the code baselines — 25 ft for a recreational fire, 15 ft for a portable outdoor fireplace — then apply whichever local or manufacturer figure is stricter.

Do gas fire tables have the same clearances? No — they are appliances with a listing, and the manual states their required clearances. Do not apply the wood-fire figures to them.

Is a spark screen required? Some jurisdictions require one on recreational fires. It is good practice regardless.

Can I burn under a pergola? Not with anything that has combustible material overhead. Overhead clearance is a manufacturer requirement, not a preference.
