Gas Line for a Generator, Fire Pit or BBQ in Silverdale, WA

Running a gas line to a standby generator, fire pit or built-in BBQ in Silverdale, WA is a permitted plumbing job. Kitsap County issues the permit, a licensed plumber sizes and runs the pipe, and the line is pressure-tested before the gas goes on. A short outdoor run to a grill or fire feature usually costs about $300 to $1,300 in 2026. A generator line costs more, because the pipe is larger and longer.

Start With the Appliance: How Much Gas Does It Need?

Every gas line is sized from the appliance at the end of it, measured in BTU per hour. Generac’s fuel-consumption guide lists a 22 kW Guardian at 327 cubic feet of natural gas per hour at full load. It also says the fuel supply and pipe must be sized at 100 percent load. Natural gas carries about 1,000 BTU per cubic foot, so that generator needs roughly 327,000 BTU per hour.

A 22 kW unit draws more than eight times what a three-burner grill does. The ¾-inch line that already feeds a range or dryer cannot be tapped for it. A standby generator gets its own larger line from the meter, and the meter itself is checked for capacity. Generac says to verify the meter can supply the generator plus every other gas appliance at once.

A fire pit or grill is the opposite case. Most 12-inch fire rings top out around 90,000 BTU, the rating on Starfire Direct’s standard 18-inch burner kit, and a Weber Genesis E-335 runs 39,000 BTU on its main burners. Those loads can usually branch off an existing manifold on a short ½-inch or ¾-inch run, as long as the rest of the system still has headroom.

Natural Gas or Propane in Silverdale?

Cascade Natural Gas lists Silverdale, Bremerton, Port Orchard and Poulsbo among the Washington communities it serves, so most established Silverdale neighborhoods have natural gas mains at the street. If your home already has a gas meter, the new appliance line starts there.

Homes beyond the mains run on propane from a tank. Propane vapor carries about 2,500 BTU per cubic foot, so the pipe can be smaller for the same appliance. The tank and regulator must still keep up: Generac rates the same 22 kW Guardian at 3.9 gallons of propane per hour at full load. Our guide to gas line installation on Bainbridge Island covers propane systems in more depth.

Permits and Inspection: Kitsap County, Not a City Hall

Silverdale is unincorporated, so there is no city building department. Gas piping permits come from the Kitsap County Department of Community Development in Port Orchard, and applications go through the county’s online permit center. The county’s “Do I Need a Building Permit?” guide lists “Gas Lines — Install or Relocate” as its own project type. It also notes that plumbing and mechanical permits can be required even when a building permit is not.

Kitsap’s 2026 fee schedule bases mechanical and plumbing fees on project valuation, with a $75 minimum. The county inspector works from a residential gas piping checklist that references the International Residential Code, the International Fuel Gas Code and Washington’s amendments.

The pressure test is the step that matters most. Under IFGC Section 406.4, the test pressure must be at least 1.5 times the working pressure and never less than 3 psig. A single-family system holds that pressure for at least 10 minutes. Here is how the job runs from first call to first flame:

1. Estimate and load calculation. We add up the BTU rating of the new appliance and everything already on the system, then size the pipe for the longest run.
2. Permit. We pull the Kitsap County gas piping permit before any pipe goes in.
3. Rough-in. Black iron or CSST indoors, and buried polyethylene with tracer wire for underground runs to a generator pad or fire pit.
4. Pressure test and inspection. The line is pressurized with air and held on a gauge for the county inspector, with the gas off.
5. Connection and leak check. Shutoff valve, sediment trap where required, flexible connector, then a leak test at every joint before the appliance is lit.

Short Runs vs. Underground Runs

A short run feeds a grill or fire table on a deck or patio within about 25 feet of an existing line. The pipe comes through the rim joist or a crawl-space wall and ends at a shutoff with a quick-connect. There is no trenching, and most of these finish in a day.

An underground run reaches a generator pad, a detached shop or a fire pit out in the yard. The pipe is buried below the depth the code and the inspector require, with a riser at each end and tracer wire so the line can be located later. Trenching through a Silverdale lawn, rockery or driveway is what moves the price, not the pipe itself.

What a Gas Line Costs in Silverdale in 2026

The ranges below come from national 2026 pricing data and from our own published Silverdale pricing. Kitsap County labor runs above the national average, so expect the upper half of a national range here.

Worked example: a 22 kW generator on a pad 50 feet from the meter, fed by a buried line. At $20 to $25 per foot the pipe is $1,000 to $1,250, trenching adds $250 to $600, and the permit and test add about $150 to $200. That puts most Silverdale generator lines at $1,400 to $2,100 before any meter upgrade. The arithmetic is ours, using the per-foot figures above.

Pricing disclaimer: The cost estimates above are based on current regional market research and industry data as of 2026. Actual prices vary depending on home size, material choices, site conditions, labor rates, and other project-specific factors. Always request a free, written estimate from a licensed local contractor before budgeting for your project. Contact Pelican Plumbing for a no-obligation quote.

Why a Gas Fire Pit Beats a Wood One in Kitsap County

Here is the Kitsap-specific reason to plumb a fire feature instead of burning wood. The Puget Sound Clean Air Agency covers Kitsap, King, Pierce and Snohomish counties, and it calls Stage 1 burn bans when wildfire smoke or winter inversions settle in. During a Stage 1 ban it prohibits charcoal barbecues, wood fire pits, chimineas and fire bowls. Its rules state that natural gas and propane grills, stoves and inserts are still OK to use.

In practice the wood pit sits cold on the exact August evenings people want to be outside, while the plumbed gas feature keeps running. Check the current status at pscleanair.gov before lighting anything during smoke season. The Kitsap County Fire Marshal also runs a separate fire-safety burn ban for open flame in dry weather.

Generators: What the Plumber Does and What the Electrician Does

A standby generator is two trades. Pelican Plumbing handles the fuel side through our gas piping services: the dedicated line from the meter or tank, the manufacturer’s regulator, the shutoff and sediment trap, the pressure test and the county inspection. A licensed electrician installs the transfer switch and ties the generator into the panel. The permits are separate, and we coordinate the gas rough-in so the unit is ready when the electrical inspection passes.

If your home’s gas system is already working hard, read the signs you need a gas line upgrade in Kitsap County before adding a generator. Our Kitsap County gas line installation guide covers whole-house costs and the permit process in more detail.

Frequently Asked Questions

Do I need a permit to run a gas line to a generator or fire pit in Silverdale, WA?

Yes. Silverdale is unincorporated Kitsap County, so the permit comes from the Kitsap County Department of Community Development, not a city office. The county lists gas line installation and relocation as its own permit type. The line is inspected after a pressure test and before the appliance is connected.

How much does it cost to run a gas line to a fire pit or BBQ in Silverdale?

Most short outdoor runs cost between about $300 and $1,300 in 2026. Thumbtack’s July 2026 data puts a grill hookup at $303 to $1,030 and a fire pit line at $382 to $1,299. A buried run across a yard, or a new meter, pushes the total higher.

What size gas line does a 22 kW generator need?

Larger than any other appliance in the house. Generac rates a 22 kW Guardian at 327 cubic feet of natural gas per hour at full load, about 327,000 BTU per hour, and the pipe must be sized for that. In most Silverdale homes that means a dedicated 1-inch or larger line from the meter, plus a check that the meter can supply the generator and the house together.

Can I use a natural gas fire pit during a burn ban in Kitsap County?

The Puget Sound Clean Air Agency’s Stage 1 rules prohibit charcoal and wood-burning fire pits, chimineas and fire bowls, and state that natural gas and propane grills, stoves and inserts are OK to use. Confirm the current ban status and the rules for your specific fire feature at pscleanair.gov before lighting it.

Can I tap my existing range or furnace line for a generator?

Almost never. A 22 kW generator draws more than eight times the gas of a three-burner grill, and a ¾-inch branch that was sized for a range cannot carry it. A standby generator gets its own line from the meter, sized for the full-load BTU rating on the unit’s fuel data decal.

Does Pelican Plumbing install propane lines as well as natural gas?

Yes. We install, extend and repair both natural gas and propane lines for homes and businesses across Kitsap County, including Silverdale, Bremerton, Port Orchard, Poulsbo and Bainbridge Island. Every line is pressure-tested to code before we turn the gas on.
