What affects the cost?
- Distance from the meter or main to the appliance — pricing runs by installation type: extensions $10-$20/linear ft, brand-new lines $15-$25/linear ft, and full replacements $23-$35/linear ft (Fixr)
- Pipe material — HDPE and CSST run cheaper installed than black iron, which costs $15-$30/linear ft versus $10-$21/linear ft for HDPE or copper (Fixr)
- Which appliance is being connected — indoor appliances like a range, dryer, or water heater typically run about $20 per linear foot, while outdoor grills, fire pits, and generators run $20-$25 per linear foot (Bob Vila, HomeAdvisor)
- Trenching for outdoor runs, which adds $4-$12 per linear foot on top of pipe and labor (Fixr, HomeAdvisor)
- Permits and inspections — most municipalities charge $100-$300 for a permit plus $50-$75 for a required inspection (HomeAdvisor, Bob Vila)
- Labor rates, which vary widely by region and licensed-plumber demand, from $45 to $200 per hour (Bob Vila, HomeAdvisor)
- Extra hardware the job may need — a new gas meter runs $300-$600 and a shut-off valve runs $300-$500 installed if the existing setup can't support the added line (Bob Vila, HomeAdvisor)
Why does gas line installation cost so much?
Gas line pricing comes down to two things: how far the pipe has to run, and what kind of job it is. A typical project costs $271 to $1,350, averaging around $558 nationally (Bob Vila, HomeAdvisor), and Thumbtack’s data lands close by — homeowners paying around $470 on average, with a $268 to $841 range for most jobs. Per linear foot, an extension off an existing line runs $10 to $20, a brand-new line $15 to $25, and a full replacement $23 to $35 (Fixr). Material adds another swing: HDPE and CSST install for $10 to $21 per linear foot, while black iron — sturdier but harder to work with — runs $15 to $30 (Fixr). Fixr’s overall average sits noticeably higher at $800, which its own breakdown suggests reflects a mix weighted toward longer new-installation and replacement runs rather than a short single-appliance hookup.
How much does it cost to hook up specific appliances?
Most indoor appliances price about the same per linear foot, since the run is usually short and simple. A gas oven or range, a dryer, and a water heater or furnace each run roughly $10 to $20 per linear foot installed (Fixr, Bob Vila, HomeAdvisor). Outdoor connections cost more per foot: a grill runs $10 to $25, a fire pit $15 to $25, and a whole house generator or pool heater $20 to $25 per linear foot (Fixr, Bob Vila, HomeAdvisor) — reflecting longer runs and, often, the outdoor labor and trenching those jobs require. Thumbtack’s job-total figures tell the same story at a higher altitude: an indoor appliance hookup runs $431 to $1,465 all-in, while an outdoor hookup runs $473 to $1,609, and a full new line run from the street runs $382 to $1,298.
What do permits, inspections, and outdoor trenching add?
Almost every gas line job needs a permit, and most jurisdictions inspect the work before it’s signed off. Hendrik Vandepoll, master plumber and co-owner of Service Force Plumbing, told Bob Vila, “In our area, at least, any gas installation requires a permit and installation by a licensed plumber.” Permits typically run $100 to $300, and inspections add $50 to $75, though HomeAdvisor and Bob Vila both note inspection fees can reach $300 in areas with stricter code enforcement. For outdoor runs, trenching is the other major line item most homeowners don’t budget for upfront — it adds $4 to $12 per linear foot on top of the pipe and labor cost itself (Fixr, HomeAdvisor). If the job needs a new gas meter because the existing one can’t support the added load, that’s another $300 to $600, and a new shut-off valve runs $300 to $500 installed (Bob Vila, HomeAdvisor). Labor itself varies by region and licensed-plumber demand, running $45 to $200 per hour (Bob Vila, HomeAdvisor).
How to lower your gas line installation cost
- Keep the run as short as possible. Since pricing is per linear foot, tapping into the nearest existing line — rather than running a new branch across the house or yard — is the single biggest lever on total cost.
- Choose HDPE, CSST, or copper over black iron where code allows. Those materials install for $10 to $21 per linear foot versus $15 to $30 for black iron (Fixr).
- Bundle indoor appliance hookups together when possible — a tankless water heater or furnace replacement done alongside a range or dryer hookup means one service call and one inspection instead of several.
- Confirm your permit and inspection costs with your local building department before you get quotes, since they range widely — $100 to $300 for the permit alone (HomeAdvisor) — and some contractors bake this into their bid while others bill it separately.
- Get multiple quotes for any outdoor run, since trenching, distance, and whether a new meter or shut-off valve is needed can swing an outdoor hookup from a few hundred dollars to well over a thousand (Thumbtack, HomeAdvisor).
Prices vary by region, appliance, and how far the line has to run, so treat the figures above as a planning budget. Get two or three local quotes, and confirm upfront whether permits, inspection, trenching, and any new meter or valve are included in the bid.

Frequently asked questions
How much does it cost to run a gas line?+
Most homeowners pay $271 to $1,350 for a typical gas line project, averaging around $558 (Bob Vila, HomeAdvisor). Larger jobs — a long outdoor run with trenching, a new meter, and permits — can push the total from about $120 for a short indoor hookup up to $5,000 (HomeAdvisor, Fixr).
How much does gas line installation cost per linear foot?+
Extending an existing line runs $10 to $20 per linear foot, a brand-new line $15 to $25, and a full replacement $23 to $35 (Fixr). Material matters too — HDPE and copper install for $10 to $21 per linear foot, while black iron runs $15 to $30 (Fixr).
How much does it cost to run a gas line to a stove or range?+
Connecting a range or stove typically runs $10 to $20 per linear foot installed (Fixr, Bob Vila, HomeAdvisor) — most kitchen hookups need only a few feet of pipe, so the job-level cost is often on the lower end of the overall range.
How much does it cost to run a gas line to a dryer?+
A dryer hookup costs about $10 to $20 per linear foot (Fixr, Bob Vila), similar to a range or water heater since it's usually a short indoor run from an existing line.
How much does it cost to run a gas line to an outdoor grill or fire pit?+
Outdoor grill hookups run $10 to $25 per linear foot and fire pits $15 to $25 (Fixr, Bob Vila, HomeAdvisor) — pricier than indoor appliances because the run is often longer and may require trenching.
Do I need a permit to install a gas line?+
Yes, in most areas. Permits typically cost $100 to $300, and a required inspection adds another $50 to $75, sometimes up to $300 in areas with stricter code enforcement (HomeAdvisor, Bob Vila, Fixr).
How much does trenching cost for an outdoor gas line?+
Trenching runs $4 to $12 per linear foot on top of the pipe and labor cost itself (Fixr, HomeAdvisor) — a factor that pushes total cost up noticeably for a line running out to a grill, fire pit, or generator.
Why do gas line cost estimates vary so much between sources?+
National averages range from about $470 to $598 for a typical hookup (Thumbtack, HomeAdvisor) up to $800 at Fixr, whose per-linear-foot data leans toward longer new-installation and full-replacement jobs rather than a single short appliance connection — and per-linear-foot figures span $0.2 to $35 depending on whether that's raw pipe material or a fully installed run (HomeAdvisor, Fixr).

Three sources cluster closely on the whole-project average for a typical hookup: Bob Vila ($558, typical range $120-$1,350), HomeAdvisor ($598, normal range $271-$936), and Thumbtack (homeowners paying around $470 on average, range $268-$841 for the middle of its data, extremes $119-$1,964). Fixr reports a higher average ($800, range $500-$2,000, extremes $200-$5,000), which its own per-linear-foot breakdown suggests reflects a mix that leans toward longer new-installation and full-replacement runs rather than a single short appliance hookup. national_average_usd here is anchored to Bob Vila's figure since it sits at the center of the three-source cluster; range_low_usd/range_high_usd are anchored to HomeAdvisor's low end and Bob Vila's high end to cover the realistic spread of a typical single-appliance job. project_low_usd/project_high_usd (from HomeAdvisor's and Bob Vila's shared low extreme of $120 up to Fixr's stated high-end of $5,000) captures the full range from a short indoor hookup to a long outdoor run with trenching, a new meter, and permit costs stacked on top. by_type figures (per linear foot, installed) are drawn from the appliance-specific rates that Fixr, Bob Vila, and HomeAdvisor all publish, using the widest low-high span any of the three cites per appliance. Figures generally cover pipe, fittings, and labor for the hookup itself; trenching, meters, shut-off valves, permits, and inspections are priced separately by most sources and are broken out in cost_factors rather than folded into the per-linear-foot appliance rates.
