Co-op Board Approval for a Fireplace: What Boards Ask For

In a Manhattan co-op or a Brooklyn condo, the fireplace you choose is only half the project. The other half is the package your board and managing agent want before anyone opens a wall. Get it right and approval moves at the building's normal pace. The easiest path almost always runs through our electric fireplaces, and this guide explains why.

Still deciding whether your apartment can take a fireplace at all? Start with our guide to adding a fireplace to an NYC condo, co-op or penthouse, then come back here for the approval process.

Electric vs gas: what will the board review?

A typical picture. Your building's agreement decides the details.

What is an alteration agreement?

It is the binding contract between you and the co-op corporation or condominium that governs renovation work in your unit. Brick Underground describes it as the document that sets the building's rules and lists what you must submit, including fees, insurance and when work can happen.

Start by asking the managing agent for the alteration application. The agent works with the board, and often the building's architect or engineer, to review what you send. Read the agreement before you commit to a design: it tells you whether new gas work is allowed and whether work is limited to certain months.

What do co-op and condo boards ask for?

Every building writes its own agreement. This is the typical list Brick Underground and Habitat describe.

Architect or engineer drawings

Where DOB permits are involved, Brick Underground notes the plans should come from an architect or engineer licensed in New York. The building's own architect or engineer usually reviews them, commonly billed to the owner at an hourly rate.

Insurance certificates

Every contractor and subcontractor typically provides a certificate of insurance naming you, the managing agent and the co-op corporation (or condominium) as additional insureds. Brick Underground reports that NYC buildings generally look for general liability of at least one million dollars per occurrence and two million in aggregate, plus workers' compensation and disability coverage. Some agreements also ask for umbrella coverage.

Licensed trades

Boards typically want proof of NYC licenses for the electrician and plumber, and Brick Underground notes that out of state licenses are not accepted. In buildings built before 1978, the contractor may also need EPA lead-safe firm certification.

Work hours, schedule and deadlines

Many buildings allow work only on weekdays during set daytime hours, and some limit major work to the summer. Agreements usually set a completion date, with a per day penalty for overruns and a procedure for extensions.

Fees and deposits

Expect an application or review fee, a refundable security deposit, and sometimes a fee for building staff time such as service elevator use. Amounts vary widely by building, and the agreement lists them.

Do you need a DOB permit for a fireplace?

It depends on the work, and the board will want to see whatever the city requires. Here is what the NYC Department of Buildings says.

• Electrical. DOB requires a permit for most electrical work, performed by a DOB licensed electrical contractor. A new circuit for a built-in electric fireplace falls here.
• Gas. DOB treats gas piping as plumbing. Work beyond its Limited Plumbing Alteration (repair) scope requires a permit, a licensed master plumber, and drawings from a professional engineer or registered architect. A new gas line to a fireplace is not a repair.
• Sign off. Boards typically want proof that permits were closed with DOB, then inspect the finished work themselves.

Two city rules come up often. Local Law 154, the gas ban, applies to new building filings, not to an ordinary renovation of an existing apartment; our Local Law 154 guide explains it. And vent-free gas fireplaces cannot be installed in New York City, so a gas fireplace in an apartment means a sealed, vented unit. See our NYC fireplace code guide.

How long does co-op board approval take?

There is no standard timeline. Brick Underground reports that board approval typically takes at least one or two months, and that incomplete submissions can add months. The building's architect or engineer generally starts only once the package is in, and their questions must be answered before the board votes.

In our experience, two things shorten the wait: a complete package submitted exactly as the managing agent asks, and a scope the board already understands, such as an electric fireplace on an interior wall.

Why do electric fireplaces simplify board approval?

Because nothing happens outside your walls. An electric or water vapor fireplace has no combustion, flue, gas line or facade penetration. To a managing agent it reads as carpentry, finishes and a circuit, the kind of alteration boards review routinely. Many units run at 1,500 watts on 120 volts; larger models can be hardwired at 240 volts, and the building may ask for a load letter.

Water vapor models are the one variation to plan for. A plumbed water feed, like the one on the Dimplex Optimyst Linear 46, is plumbing work, and some boards will review it under their wet work rules. Browse our water vapor fireplaces or linear electric fireplaces to compare.

What does a gas fireplace add to the review?

A sealed direct vent gas fireplace is possible in some existing apartments, but it changes the review in three ways.

A new gas line

The apartment needs gas service with capacity and a new branch to the fireplace: a licensed master plumber, a DOB filing with engineer or architect drawings, and work near the building's riser. Brick Underground notes agreements typically prohibit relocating risers, and some buildings refuse any new gas branch. Ask before you design around it.

Venting through the facade or roof

A direct vent unit draws air from outside and exhausts outside, so the vent must reach an exterior wall or the roof within the manufacturer's limits, with the cap clear of windows, doors, balconies and air intakes per the manual. A new opening in the facade or roof is a common element, squarely in the board's hands. On a landmarked building it can also need a Landmarks Preservation Commission permit.

The building engineer's review

Expect the engineer to review the gas route, vent route and cap location, and possibly inspect during the work.

Board approvals in Manhattan, Brooklyn and Queens

Manhattan. From prewar Upper East Side co-ops to newer condo towers, the exterior wall is usually the limit for gas, because windows and facade rules leave few places for a vent cap below the top floor. Most Manhattan approvals we help with are electric or water vapor.

Brooklyn. Brownstone condos in Park Slope and Brooklyn Heights often sit inside historic districts, so exterior work can need an LPC permit on top of board approval. An interior electric fireplace avoids that layer.

Queens. Garden co-ops in Jackson Heights, itself a designated historic district, run their own alteration processes, and interior work is again the simpler request. Our guide to the best fireplace for an NYC apartment compares the options side by side.

Which should you choose?

For most co-op and condo owners, we recommend electric. The flame quality is excellent now, and the approval reads as an ordinary interior alteration. Pursue gas only after the building confirms gas service and a vent path, and build the package around those two answers.

Frequently asked questions

Do I need board approval to install an electric fireplace in a co-op?

Usually, yes. A built-in unit involves framing and new wiring, which most agreements treat as an alteration. A plug-in freestanding unit may not, but check your house rules first.

What insurance does a co-op board require from contractors?

Typically a certificate from every contractor and subcontractor naming you, the managing agent and the corporation (or condominium) as additional insureds, with liability, workers' compensation and disability coverage. Your agreement sets the exact limits.

Does a gas fireplace need a DOB permit in NYC?

New gas piping goes beyond DOB's Limited Plumbing Alteration scope, so it needs a permit, a licensed master plumber and drawings from a professional engineer or registered architect. The fireplace must also be a vented type, because vent-free gas fireplaces cannot be installed in New York City.

Can a co-op board say no to a gas fireplace?

Yes. The board controls the building's common elements, including the gas riser, the facade and the roof, and some buildings do not allow new gas work at all. House rules can be stricter than city code, and the board's decision governs your unit.
