What the Price Covers
A direct-vent gas fireplace installed by us in a location that has never had a fireplace runs $4,450 to $8,950. That covers the fireplace unit, the framing for it, the vent pipe from the unit to the outside, the termination cap, and the gas line from the nearest supply to the unit. The permit and the city's inspection appear as their own line on the quote. Finish work around the fireplace, such as stone, tile or a custom mantel, is quoted with the design.
That range is what Sherman Oaks owners usually ask about when they want a fireplace in a family room, a primary bedroom or a room added after the house was built. A direct-vent unit is the most flexible way to do it, because it needs no chimney.
How Direct-Vent Works, and Why It Matters for the Rules
A direct-vent fireplace is sealed. A glass front closes the firebox, and a two-layer pipe runs from the unit to the outside: the inner pipe carries exhaust out, and the outer one brings combustion air in. Nothing is drawn from the room. That design is why it can go in a bedroom or a tight modern house where an open fireplace would struggle, and why it does not need a masonry chimney.
It is also a listed appliance, which means the manufacturer's instructions carry the force of code. They set the framing dimensions, the clearance to combustibles around the unit and above it, the maximum vent length and number of elbows, and where the termination may sit on the outside of the house. A termination usually has to keep set distances from windows that open, doors, air intakes, walkways, and inside corners. Those rules decide where a fireplace can go more than any design choice does.
The Permit in Sherman Oaks
Sherman Oaks is in the City of Los Angeles, so the permit comes from the Department of Building and Safety. A new direct-vent fireplace involves gas piping, a new appliance and a penetration through an outside wall or roof, all of which are permit work. The city inspects the gas line and the finished install.
The same applies in Studio City, Encino and Woodland Hills. Burbank, Glendale, Pasadena, Calabasas and West Hollywood each issue their own permits. We handle the application, the inspections and the paperwork, and you keep the signed-off permit with the unit's manual.
Why Not a New Wood Fireplace?
Some owners ask about a wood-burning fireplace instead. In most of the Valley that is a harder path. The South Coast AQMD's Rule 445 restricts wood-burning devices in new development, and even where one is allowed, it would follow the winter no-burn alerts. A wood fireplace in a new spot also needs a chimney built to the seismic rules, which is a much larger job. For most remodels, gas is the practical choice.
What Moves the Price Within the Range
Five things decide where a project falls between $4,450 and $8,950:
1. The unit. Size, heat output, linear versus traditional style, and features such as a blower, remote or a see-through design. 2. The vent route. A unit against an outside wall that vents straight out the back is the simplest. A unit on an inside wall, or one that has to vent up through the roof, needs more pipe and more work. 3. The gas line. A short run from a nearby supply is quick. A long run across the house, or an upgrade because the existing supply is undersized, adds to the cost. 4. The wall. Framing a new chase or bump-out, or opening a finished wall and patching it, changes the labor. 5. The location. Second-floor installs, tight access and roof venting on steep pitches add time.
The fastest way to a firm number is a photo of the wall where you want the fireplace, a photo of the outside of that wall, and a note on where the gas meter is. Send those three photos through the form, and we can usually tell you whether the location works with the venting rules and give you a written quote before a site visit.
Replacing an Old Factory-Built Fireplace
Many Valley houses from the 1970s and 1980s have a metal factory-built wood fireplace that has reached the end of its life, often with cracked panels and parts no longer made. Those units usually cannot take an insert unless their listing allows it. A direct-vent gas fireplace set into the same opening, with new venting, is a common fix. Because the framing and location already exist, these projects often land toward the lower part of the range.
When an Insert Makes More Sense
If the house already has a sound masonry fireplace, a gas insert is usually the better buy. It uses the existing firebox and chimney with a new liner, and installed it runs $2,750 to $5,550. A direct-vent fireplace makes sense when there is no fireplace where you want one, or when the existing one cannot be used.
Planning the Finish
The fireplace's listing also sets what can surround it: how close a wood mantel can sit above the opening, which materials can touch the unit's face, and whether a TV recess is allowed above. We give you those numbers before your designer draws the wall, so the finished room passes inspection without changes.
