Gas fireplace installation in Bellevue.

Bellevue is home base. Every install pulls a City of Bellevue mechanical permit, gets inspected, and goes into a room that's been thought about as a whole — not a wall with an appliance bolted on.

Three Bellevue install rooms

What an Eastside
install looks like.

Bellevue's housing stock spans 1940s Craftsmans in Bridle Trails to 1980s ranches in West Bellevue to brand-new Lakemont great rooms. The right gas fireplace install depends on the room context first — the appliance choice comes second. Three install types we run regularly.

Modern gas fireplace installed in a Bellevue living room with clean surround and warm lighting
Lakemont

New-construction great room

Linear direct-vent install in a 22-foot great room. Heat & Glo Mezzo with single-material porcelain surround, no mantel, ribbon flame as the visual anchor of the floor.

West Bellevue

1980s remodel + insert

Existing brick firebox from the original build. Valor H5 radiant insert with a new tile surround and a reclaimed-beam mantel. The firebox stays, everything around it changes.

Bridle Trails

New-construction Craftsman

Mendota FullView with traditional brick surround and a substantial millwork mantel. New chase framed during build, vented vertically through the roof.

The Bellevue permit workflow

What the city actually requires.

Every gas fireplace install in Bellevue triggers two city permits and at least two inspections. Prime pulls every permit, schedules every inspection, and walks every inspector. You should never be the one calling the city.

  1. 01

    Mechanical permit

    Pulled through the City of Bellevue Development Services Department for the appliance install itself. Covers the unit placement, clearance to combustibles, and venting path.

  2. 02

    Gas piping permit

    Separate permit for the gas line. Covers pipe sizing per BTU load, shut-off valve placement, and the required pressure leak test before the line goes live.

  3. 03

    Inspections

    Typically two: a piping inspection (gas line pressure-tested in the wall before drywall closes up) and a final inspection (full system live, controls tested). Some scopes add a framing inspection.

  4. 04

    L&I sticker

    Washington State Labor & Industries requires a sticker affixed to every new gas appliance install. Separate from the city — a state requirement layered on top.

Current fees are published at bellevuewa.gov. We track current Bellevue, Mercer Island, Kirkland, Redmond, and Issaquah fee schedules so the estimate doesn't drift between quote and install.

Match the unit to the era

The right install
for the right house.

Bellevue's neighborhoods come from different decades, with different chimneys, different framing, and different design vocabulary. The unit that's right in a Lakemont new-build is wrong in a Bridle Trails Craftsman — and vice versa.

Bridle Trails, Vuecrest, Enatai

Pre-1980 Craftsman / Tudor

Existing masonry firebox is usually the right starting point. A radiant gas insert (Valor H5, Mendota DXV) keeps the room's character and warms it properly. Surround stays traditional — reclaimed-wood mantel, tile or stacked stone.

Phantom Lake, Newport, Eastgate

1980s-1990s remodel candidates

Mid-era brick fireboxes that were never quite right. Insert + new surround is the highest-leverage move — the firebox stays, the room gets reset. Heat & Glo or Napoleon land here often.

Lakemont, Somerset, Newport Hills

Post-2000 new construction

Newer chases support direct-vent or linear installs. Heat & Glo Mezzo or Mendota FullView in a single-material surround. No chimney needed — vent goes through the wall or chase.
