Do I need a permit to build a fire pit or outdoor fireplace?
It depends on the specifics
A portable wood fire pit is generally not a building-permit item at all — it is governed by fire and open-burning rules instead. Plumb gas to it and the gas line is regulated work in nearly every jurisdiction.
What changes the answer
- Portable wood or propane unit on a patio — normally no building permit; the fire code's separation distances still apply
- A permanent masonry fire pit or outdoor fireplace — commonly a permit, and an outdoor fireplace with a chimney nearly always
- Any permanent natural gas connection — a fuel gas permit, and the line has to be pressure tested
- Recreational fires are generally kept 25 feet from a structure, and portable outdoor fireplaces 15 feet, under the fire code
- Local burn bans, seasonal restrictions and air-quality rules are separate from all of the above and change without notice
These thresholds come from the model code and are commonly amended locally, which is usually where people get caught.
Why it matters
The building department is rarely the constraint here; the fire marshal and your insurer are. Separation distance from the house, from fences and from anything overhanging is what actually prevents the failure, and a gas line assembled without a pressure test is a leak nobody finds until it has collected somewhere.
Confirm the requirement with the authority that would issue the permit before deciding.
The version of this people actually ask
Do I need a permit for a portable propane fire pit?
Essentially never, as a building permit. A self-contained unit with a bottle underneath is an appliance you could carry away, and no building work is happening. What still applies is the fire side: separation from the house and from combustibles, any seasonal burn ban, and the manufacturer's clearances — which are also what your insurer will point at if something goes wrong.
Do I need a permit for a built-in gas fire pit?
For the gas, almost certainly. Running a fixed line from the meter to a fire feature is regulated fuel gas work in nearly every jurisdiction: sizing for the appliance's demand, the shutoff, and a pressure test on the finished line. The masonry it sits in may or may not need its own permit depending on size and height, but the gas is the part that reliably does.
How far does a fire pit have to be from the house?
The fire code's usual figures are 25 feet from a structure for a recreational fire and 15 feet for a portable outdoor fireplace, with an exception for portable units at one- and two-family dwellings. Local ordinances routinely set their own numbers, and manufacturers state their own clearances. Overhead is the dimension people forget: an eave, a low branch or a pergola directly above is a hazard nothing in a setback measurement captures.
Do I need a permit to build a stone or brick fire pit myself?
A low masonry ring at grade is usually treated like other flatwork and often needs nothing. It changes as it gets taller and more enclosed: an outdoor fireplace with a chimney is a structure with combustion in it, and that is generally permitted and inspected. Somewhere between a knee-high ring and a chimney your jurisdiction draws a line, and it is usually written down.
This is the typical rule, not your answer
This is the typical rule in the United States and not a decision about your property — permitting is run by more than 22,000 separate authorities and any of them can amend the code it adopts, so confirm with your local building department before you start. Put a ZIP in to see what applies in that state, and how to reach the office that decides.
Fire pits are not in the IRC R105.2 exemption list because they are generally not building-code items. Separation distances come from International Fire Code section 307 — 307.4.2 for recreational fires and 307.4.3 for portable outdoor fireplaces. A permanent gas supply falls under IRC Chapter 24 / the International Fuel Gas Code, which is not exempt work.

- Build a deckA permit is usually required once a deck is more than 200 square feet, more than 30 inches above grade, serves an exit door, or is attached to the house.
- Put up a fenceFences under 7 feet are typically exempt from a building permit — but height limits, corner-visibility rules and pool-barrier requirements are set locally and catch people constantly.
- Add a shed or small outbuildingOne-story detached sheds are typically exempt up to 200 square feet under the residential code — but the number people quote is 120, and both are right depending on which code your jurisdiction adopted.
