How Far Should a Fire Pit Be From a House? 10 to 25 Feet

Most codes set 10 to 25 feet from structures, but overhead clearance catches more people out. What to measure from, and why local rules decide it.

Ten to twenty-five feet from any structure is where most codes and manufacturers land. But there is no national number — this is set locally. And the clearance people get wrong is usually the one above their heads.

What the distance is measured to

Not “the house”. Codes generally say structures and combustible materials.

Everything the clearance applies to
Counts?
House wallYes
Timber fenceYes
Shed, garage, pergolaYes
DeckYes
WoodpileYes
Propane cylinderYes, with its own separate rules
Property lineOften, yes

The common version of this mistake

Someone measures twenty feet carefully to the house, sites the pit there, and it ends up four feet from a timber fence.

Same hazard, shorter distance, and the fence is drier than the house.

Overhead is the one that bites

Ground distance gets measured. Vertical clearance rarely does — and it matters more, because heat and embers go up.

  • Overhanging branches
  • Eaves and gutters
  • Pergola roofs, awnings, sail shades
  • Washing lines

A commonly quoted figure is ten to fifteen feet of clear space above. The practical version is blunter: if something is above the pit, the pit is in the wrong place.

Propane is different, but not exempt

Shorter clearances are common — no flying embers, and the flame stops when you turn it off.

But the manufacturer’s figures are the ones that apply, the cylinder has its own siting rules, and many places that restrict wood burning permit gas under different conditions. Worth checking if open burning is prohibited where you are.

Before you site it at all

Distance is not the only rule, and sometimes not the binding one

  • Is open burning permitted? This varies by season and by air-quality rules, and in some places it is simply banned
  • Is a permit required?
  • What does the HOA say?

One call to the local fire department covers all of it, and gives you a number that actually applies rather than a range off the internet.

Wind beats distance

A legal clearance on a still evening is a different proposition at twenty miles an hour.

Most guidance says do not burn in high wind regardless of siting — because the ember plume stops going up and starts going sideways, and no reasonable distance covers that.

Common questions

How far does a fire pit need to be from a house?

Ten to twenty-five feet from any structure is the range most local codes and manufacturers settle on, with ten feet common as an absolute minimum and twenty-five appearing in stricter jurisdictions. There is no single national figure, because this is set locally. Your fire department or building department will give you the number that actually applies to you, usually in one phone call.

Does the rule apply to fences and sheds too?

Yes — the wording in most codes is structures and combustible materials, not houses specifically. That covers fences, sheds, garages, pergolas, decks, woodpiles, propane tanks and the neighbour's property line. People measure carefully to the house and then site the pit four feet from a timber fence, which is the same hazard with a shorter distance.

What about overhead clearance?

It catches more people out than the ground distance, and it matters more. Overhanging branches, eaves, gutters, pergola roofs, awnings and washing lines all sit directly in the heat and ember plume. A commonly quoted figure is at least ten to fifteen feet of clear space above, and the practical test is simpler: if anything is above the pit, it is in the wrong place.

Is the distance different for a propane fire pit?

Often shorter, because there are no flying embers and the flame stops the moment you turn it off, but it is not zero. Manufacturers specify their own clearances and those are the ones to follow, and the propane cylinder itself has separate siting rules. Many jurisdictions that restrict wood burning permit gas appliances under different conditions, which is worth checking if wood is prohibited where you live.

Can a fire pit go on a deck?

A wood-burning one, generally not — embers and radiant heat through the deck boards are both real problems, and most decking manufacturers void warranties over it. Gas and propane units designed for deck use exist and are the practical answer, used with a proper heat shield underneath. Composite decking is worse than timber here, not better, because it softens and deforms at lower temperatures.

What else should I check besides distance?

Whether open burning is permitted at all, which varies by season and by air quality rules; whether a permit is required; what your HOA says; and the wind. A legal distance on a still evening is a different proposition in a twenty-mile-an-hour wind, which is why most guidance says not to burn in high wind regardless of how far away the house is.
