Fireplace rules in New York City are stricter than almost anywhere else in the country, and which rules apply depends on the fuel. Wood is governed one way, gas another, and electric and ethanol barely at all. After three decades of installing fireplaces across the five boroughs, Nassau, Suffolk and Westchester, this is the practical guide we wish every customer had before they started shopping for a gas fireplace, an electric fireplace or an ethanol fireplace.
The short answer
In NYC you can install a vented (direct vent) gas fireplace, a vented gas log set in an existing firebox, an electric fireplace, or a bioethanol unit. You cannot install a new wood-burning fireplace, and vent-free gas is not permitted. Gas work needs a Licensed Master Plumber and, in nearly every case, a DOB permit.
Key takeaways
- Legal in NYC: direct vent gas, vented gas logs or a gas insert in an existing firebox, electric, water vapor and bioethanol. Not legal: new wood-burning fireplaces and any vent-free gas unit.
- Every gas hookup is a DOB permit and a Licensed Master Plumber. A handyman or an out-of-state installer cannot legally run gas in the city.
- Since June 26, 2023, a vented gas fireplace manufactured on or after that date must meet New York State efficiency standards. Ask for the NYSERDA listing before you buy.
- In a co-op or condo the facade usually decides it: no exterior vent means electric, water vapor or ethanol.
- A grandfathered wood fireplace can lose its status in a gut renovation. Check with the DOB before demolition.

Which codes govern fireplaces in NYC?
Three bodies of law do most of the work. They overlap, and the Department of Buildings (DOB) enforces two of them.
- NYC Mechanical Code. Covers solid fuel appliances, factory-built fireplaces and chimneys. Local Law 38 of 2015, effective May 6, 2016, added Section 901.3, which requires solid fuel-burning fireplaces and appliances to conform to the Air Pollution Control Code and limits new ones to fuel types that code allows. In practice this is the provision that ended new wood-burning fireplaces in the city.
- NYC Fuel Gas Code. Governs every gas-fired appliance: direct vent fireplaces, gas inserts, vented gas log sets, outdoor gas fire features and the piping that feeds them. It is the code that keeps vent-free gas out of New York City.
- NYC Air Pollution Control Code (Title 24 of the Administrative Code). Enforced by the Department of Environmental Protection. It controls what may be burned, which is why it matters for anyone with an existing wood fireplace.
New York State adds a fourth layer for gas fireplaces: the state appliance efficiency standards administered by NYSERDA. More on that below, because it changed what manufacturers can sell here.
What is allowed, fuel by fuel?
This table is the one-minute version. The rest of the guide explains the why.
| Fireplace type | Status in NYC | What it takes |
|---|---|---|
| New wood-burning fireplace | Not permitted | Mechanical Code 901.3 (Local Law 38 of 2015) |
| Existing wood-burning fireplace | May be used and maintained | Burn only what the Air Code allows; keep the chimney inspected |
| Direct vent gas fireplace | Permitted | Listed appliance, exterior vent, LMP gas work, DOB permit |
| Vented gas log set or gas insert | Permitted in an existing, sound firebox and flue | Chimney inspection, LMP gas work, DOB permit |
| Vent-free (ventless) gas | Not permitted | Do not buy one for a NYC address |
| Electric fireplace | Permitted | Outlet or a licensed electrician for hardwired units |
| Bioethanol fireplace | Permitted, with building and fuel-storage caveats | Board approval, follow manufacturer clearances |
Which gas fireplace rules matter most?
Vented is the rule. Gas fireplaces sold for New York City are listed vented appliances: decorative vented fireplaces tested to ANSI Z21.50, vented fireplace heaters tested to ANSI Z21.88, and vented gas logs tested to ANSI Z21.60 for use in a real firebox. Every one of them pushes combustion products outside. The NYC Fuel Gas Code does not allow unvented gas room heaters, gas logs or fireplaces, so any "vent-free" or "ventless" gas product you see online cannot be installed in the five boroughs, no matter how it is marketed. Our store carries vent-free products for customers in parts of the country that allow them. We do not install them at New York City addresses.
Direct vent is the practical answer. A direct vent gas fireplace is a sealed box: a coaxial pipe pulls combustion air from outside and sends exhaust back out, usually through an exterior wall or up through a roof. No chimney required, no room air consumed. That is why it is the default choice for brownstones, townhouses and any apartment with an exterior wall it is allowed to penetrate.
New York State efficiency standards. Since June 26, 2023, vented gas fireplaces manufactured on or after that date must meet New York State's appliance efficiency standard to be sold, leased or installed in the state. The NYSERDA summary spells out three requirements that affect what you can buy:
- The unit must automatically shut off the pilot flame when the main burner goes out.
- It must prevent any ignition source for the main burner from running continuously for more than seven days after the last use. Units with intermittent pilot ignition already comply.
- Decorative fireplaces (no thermostat, not sold as heaters) must be direct vent, unless marked "for replacement use only."
Vented gas log sets are covered too. Units manufactured before June 26, 2023 are not. Before buying any gas fireplace for a New York address, ask for the model's listing in NYSERDA's State Appliance Standards Database; the manufacturer or dealer should be able to show it.

Measure the vent run before you fall in love with a model. Every direct vent fireplace has a maximum horizontal run and a minimum vertical rise, and both change with the number of elbows. In a prewar building with a thick masonry exterior wall, a 36 inch unit that terminates straight out the back is usually easier to get approved than a linear unit that needs to snake around a steel beam.
Do I need a permit, and who can do the work?
The Administrative Code (Section 28-105.1) requires a DOB permit to install, alter or replace any gas system. The "minor alterations and ordinary repairs" exemption specifically excludes gas distribution piping, so do not expect a fireplace hookup to slide through without a filing. Separately, Section 28-408 makes it unlawful for anyone other than a Licensed Master Plumber, or someone under an LMP's direct and continuing supervision, to perform plumbing and gas piping work in the city.
What that means for you: a handyman, a general contractor without an LMP on the job, or a fireplace installer from out of state cannot legally run or connect gas in NYC. The same applies to a "simple" conversion of an existing wood firebox to vented gas logs, because a new gas line into the firebox is gas piping work.
Unpermitted gas work shows up later. It surfaces at resale, during a co-op's annual gas inspection, or when an insurer asks for paperwork after a claim. We install what we sell, and where a permit is required we pull it.

From our install team
Co-op boards care about three things: the facade penetration, the gas line route through other people's apartments, and insurance. Bring the manufacturer's vent termination drawing, a one-page scope from the LMP, and your installer's certificate of insurance to the first board conversation. It cuts weeks off the approval.
Mistakes we see every season
- Buying a ventless gas unit online, then learning it cannot be installed anywhere in the five boroughs.
- Assuming a grandfathered wood fireplace can be relocated or rebuilt during a gut renovation. Significant alteration can end the grandfathering; talk to the DOB and your architect before demolition.
- Skipping board or building-management approval in co-ops and condos, then being told to remove the unit.
- Letting a general contractor's crew run the gas line. Only an LMP (or someone under one) can do that work in NYC.
- Ordering a gas fireplace from an out-of-state retailer that is not listed with NYSERDA, then discovering the LMP will not sign off on it.
From our install team
If you are converting a wood firebox to gas logs, get the chimney inspected and swept first. A cracked flue liner or a blocked damper fails the job no matter how good the log set is, and a damper clamp that holds the flue open is part of a legal vented log installation.

Which fireplace type should you choose for your building?
Choose electric, water vapor or ethanol if you are in a high-rise condo or co-op:
- The board will not allow a new facade penetration, or the apartment has no exterior wall to vent through.
- You want the shortest approval: a plug-in or hardwired electric fireplace touches nothing outside your unit.
- You want a real flame without a flue: a bioethanol fireplace, with board sign-off and fuel storage limits respected.
- Flame realism matters more than heat: a water vapor fireplace gives a three-dimensional flame with no combustion.
Choose direct vent gas, a gas insert or vented logs if you own a brownstone or townhouse with a chimney:
- You own the exterior wall, so a direct vent unit can terminate outside under a DOB permit.
- The old wood firebox and flue are sound: a vented gas log set keeps the open-hearth look.
- You want real heat from the same opening: a direct vent gas insert with its own liner is far more efficient than open logs.
- The vent run is short and simple. A 36 inch unit straight out the back beats a linear that has to snake around a steel beam.
Choose an outdoor gas feature if you have a single-family home with a yard:
- You want fire without the indoor venting question: outdoor gas fireplaces, gas fire pits and fire pit tables follow the Fuel Gas Code but need no flue.
- Natural gas is available. Propane storage in the city carries FDNY rules, so ask before planning around tanks.
- You still want indoor fire too: a direct vent unit inside plus a gas fire pit outside can share one permitted gas line plan.
Our recommendation: start from the vent, not the catalog. If you can legally and politically get a pipe through an exterior wall, direct vent gas is the best fire you can have in New York City and it is worth the permit. If you cannot, go electric for the easiest approval or water vapor for the most convincing flame, and treat ethanol as the real-flame option for a board that will sign off on it. In a house with a yard, run the gas line once and plan the indoor unit and the fire pit together.
Verify locally. This guide is general information, not legal advice. Codes are amended, buildings add their own rules, and the DOB, DEP and FDNY each interpret their own regulations. Confirm specifics with the NYC Department of Buildings, your building management, and a Licensed Master Plumber before buying or starting work.
Frequently asked questions
Are gas fireplaces legal in NYC apartments?
Yes, if they are vented. A direct vent gas fireplace with an approved exterior termination, installed by a Licensed Master Plumber under a DOB permit, is legal. Your co-op or condo board must also approve the work, and many boards will not allow a new facade penetration.
Can I install a ventless gas fireplace in New York City?
No. The NYC Fuel Gas Code does not permit unvented gas room heaters, gas logs or fireplaces. Vent-free products are legal in many other states, which is why you see them online, but they cannot be installed in the five boroughs.
Do I need a permit for a gas fireplace in NYC?
Yes. The Administrative Code requires a DOB permit to install or alter any gas system, and the minor-alteration exemption excludes gas distribution piping. The work itself must be done by a Licensed Master Plumber.
What is the New York State gas fireplace rule from June 2023?
Vented gas fireplaces manufactured on or after June 26, 2023 must meet state efficiency standards to be sold in New York: automatic pilot shutoff when the main burner goes out, no continuous ignition source for more than seven days after last use, and direct vent construction for decorative models. Units made before that date are not covered.
Can I put a wood-burning fireplace in my NYC renovation?
No. New solid fuel-burning fireplaces have not been permitted since Local Law 38 of 2015 took effect in May 2016. Existing wood fireplaces may be kept and used.
Do electric fireplaces need a permit in NYC?
A plug-in unit needs nothing beyond a suitable outlet. Hardwired or 240V units are electrical work and should be done by a licensed electrician, who will know whether a filing is needed for your building.
Are ethanol fireplaces allowed in NYC co-ops?
Bioethanol fireplaces do not need a vent or gas line, so the city's gas and chimney codes do not apply. Your building can still restrict them, and fuel storage in a multifamily building has limits, so get board approval and follow the manufacturer's clearances.
