Fire Pit Safety & Clearance Guide (2026)
A wood-burning fire pit should sit at least 10 feet from any structure, with 15-25 feet recommended because of flying embers. A gas or propane fire pit can often sit closer - roughly 3-6 feet - when the manufacturer publishes a clearance for it. Local fire code and the manufacturer's manual always override any rule of thumb.
How far should a fire pit be from the house?
Distance depends on fuel type. A wood-burning fire pit throws sparks and embers, so it needs the most room - at least 10 feet from any structure, and 15-25 feet is the safer recommendation. A gas or propane fire pit produces no embers, so many models are rated to sit far closer, often in the 3-6 foot range when the manufacturer publishes a clearance. Two rules sit above every number below: the fire code your jurisdiction enforces, and the clearance printed in the manufacturer's manual. Where they differ, follow the stricter one.
That difference in required space is one practical reason gas fire features suit tighter urban patios, courtyards and covered areas where a wood fire simply would not have the clearance to be legal or safe.
What the fire code actually says
The starting point across most of the United States is the NFPA 1 Fire Code, mirrored closely by the International Fire Code (IFC). Both classify a backyard fire pit as a recreational fire when the fuel area is 3 feet or less in diameter and 2 feet or less in height. For that category, the widely adopted baseline is a 25-foot clearance from any structure or combustible material - the single most-cited figure in fire pit safety.
Worth knowing: NFPA 1's underlying baseline for open outdoor fires is actually 50 feet, which local authorities typically reduce toward the 10-25 foot range for smaller, contained recreational fires. Jurisdictions then amend from there - one city may hold 25 feet for all open flames while a neighboring town drops to 15. The code number that governs your install is your local one, so confirm it with the building or fire department before you build.
Clearance by fuel type
Use this as a planning starting point, then confirm against your model's manual and local code.
| Fuel type | Min. from structure | Recommended | Embers? |
|---|---|---|---|
| Wood-burning | 10 ft | 15-25 ft | Yes |
| Natural gas | 3-6 ft* | Per manual + code | No |
| Propane | 3-6 ft* | Per manual + code | No |
*Gas clearances apply only where the manufacturer publishes them and local code allows; some jurisdictions set 10-15 ft regardless of fuel. Overhead: 18-24 in above the flame for a combustible covered patio.
Overhead and base-surface requirements
Clearance is not only horizontal. Keep the space above the fire pit open; for a combustible covered patio, allow at least 18-24 inches above the top of the flame, and keep well clear of tree branches, awnings and overhangs. The ground underneath matters just as much: install on a non-combustible surface such as pavers, gravel, concrete or stone. Avoid placing a fire pit directly on a wood or composite deck or on grass unless it is properly shielded or raised on a rated barrier.
Stone and concrete pool decks are generally non-combustible, which is why fire features integrate so well into poolside settings - though some jurisdictions add extra setback near water, so check locally.
HOA rules and permits
Local code is not the only layer. State, county, municipal and HOA rules each apply independently, and an HOA can prohibit fire pits entirely - or require gas-only models - regardless of what local code allows. Many HOAs ban wood-burning outright, which again pushes toward gas as the compliant choice. A natural gas fire pit connected to a fixed gas line generally requires a gas-fitting permit, and gas or propane units sometimes qualify for burn-ban exemptions that wood-burning pits do not.
Before buying, check three things: your municipal fire code, any burn bans in effect, and your HOA's CC&Rs.

Safe operation checklist
Once installed, safe use comes down to a few habits: never leave a fire unattended; keep a means of extinguishing it - hose, extinguisher or bucket of water - within reach; supervise children and pets at all times; and inspect the unit each season for rust, cracks or, on gas models, any sign of a leak before first use.

Frequently asked questions
How far should a fire pit be from the house?
Wood-burning: at least 10 feet, with 15-25 feet recommended. Gas or propane: often 3-6 feet where the manufacturer publishes a clearance - but always follow local code and the model's manual.
What is the NFPA rule for fire pits?
NFPA 1 classifies a fire pit as a recreational fire when the fuel area is 3 feet or less in diameter and 2 feet or less in height, with a widely adopted 25-foot clearance from structures and combustible materials.
Are gas fire pits safer than wood-burning ones?
For spark and ember risk, yes - gas produces none, which is why many models are rated for less clearance and are often the HOA-approved option.
Can I put a fire pit on a wood deck?
Only with a proper non-combustible shield or a raised, rated base. Pavers, gravel, concrete or stone are safer, and the manufacturer's requirements come first.
Do I need a permit for a backyard fire pit?
Often yes - especially for a natural gas pit on a fixed line, which typically needs a gas-fitting permit. Rules vary by jurisdiction, so check your local fire or building department and your HOA.
