Gas line installation typically costs $10-$30 per linear foot, with an average near $20 for standard residential work. The gas line cost per foot depends on pipe material, run length, access, appliance demand, local labor rates, and whether the route is indoors or underground.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed gas line | $10 per ft | $20 per ft | $30 per ft | Standard residential route with ordinary access |
| Small appliance branch | $250 | $700 | $1,500 | Short connection, fittings, shutoff, and labor |
| Longer home run | $800 | $2,000 | $5,000+ | Long route, difficult access, or capacity upgrades |
What a residential gas line costs per foot
For an accessible, straightforward interior run, homeowners commonly pay $10-$20 per linear foot, while complicated routes can reach $30-$50 per foot or more. These installed rates generally cover pipe, fittings, and labor, but may exclude permits, appliance hookups, drywall repair, trenching, and testing fees.
A short branch for a range or dryer may cost $250-$1,000; a new line for a furnace, water heater, or outdoor kitchen can run $800-$3,000 or more. Longer projects often have a lower per-foot rate but a higher total because they use more materials and require more labor. Assumptions: U.S. residential pricing, standard materials, licensed contractor, and no major utility or structural work.
Budget about $20 per foot for a basic run, then price permits, access work, and appliance connections separately.
How pipe, labor, and permits shape the quote
Quotes vary in what they include. Ask whether the contractor has counted the complete route, appliance shutoff valves, pressure testing, permits, and restoration; comparing only the per-foot figure can hide substantial exclusions.
| Quote component | Typical price | What can change it |
|---|---|---|
| Pipe and fittings | $2-$8 per ft | Material, diameter, and fitting count |
| Installation labor | $75-$150 per hour | Access, routing, and crew size |
| Permit and inspection | $50-$500 | City requirements and project scope |
| Appliance shutoff and hookup | $100-$400 per fixture | Connection type and appliance location |
| Trenching and restoration | $5-$25 per linear ft | Soil, paving, depth, and surface repair |
Some contractors quote a flat project price rather than itemizing every component. A useful estimate separates pipe, labor, permit charges, and any excavation or finish repairs.
Pipe diameter and route length can change the price
Gas demand and total developed length determine the required pipe size. A 1/2-inch branch may serve a modest appliance on a short route, while a 3/4-inch or 1-inch line may be needed for higher BTU demand, multiple appliances, or a longer run. Larger pipe costs more and can take longer to install.
For example, adding a 20-foot range branch may cost $300-$900 when the route is exposed and nearby. A 60-foot route serving several appliances could cost $1,200-$3,000, depending on sizing and access. If the meter, regulator, or existing supply cannot support the added load, upgrades may add hundreds or thousands of dollars.
Have the contractor size the line from appliance input ratings and total route length, not distance alone.
What changes between an indoor run and buried gas pipe
Accessible basement or garage piping is generally less expensive than concealed routing through finished walls. Cutting and patching drywall, drilling masonry, working in a crawl space, or crossing a finished ceiling can add $200-$1,500 or more, depending on the number of openings and the repair standard.
Buried exterior lines commonly cost more than simple exposed piping because excavation, approved materials, burial depth, warning tape, and inspection may apply. Budget roughly $20-$50 per foot for a straightforward buried run, with difficult soil, concrete, landscaping, or driveway crossings pushing the rate higher. Local code determines approved materials and installation requirements.
Confirm whether the quote includes excavation, backfill, surface restoration, and inspection before comparing underground line prices.
How labor hours and access affect installation time
A simple appliance branch may take 2-5 hours, while a longer or concealed route can require a full day or more. A two-person crew, permit appointment, pressure test, and coordination with an appliance installer may extend the calendar schedule beyond the hands-on work.
Labor often represents a large share of the total because a licensed professional must route, connect, and test the system safely. Difficult access, occupied-home protection, and work in tight crawl spaces can increase labor hours. A labor estimate of 6 hours at $100 per hour, for instance, equals $600 before materials and other charges.
Ask how many labor hours are included and whether testing and the final appliance connection are part of that allowance.
Why gas line prices differ by U.S. region
Urban markets with higher wages and permit fees may price 10%-25% above the national middle, while some rural areas may come in 5%-15% below it. Those differences are not guaranteed: limited contractor availability, long travel distances, or local inspection rules can raise rural quotes as well.
Coastal cities and dense metro areas may also have more expensive parking, building access, and restoration work. Compare at least two or three written quotes from contractors familiar with the local code. Check that each uses the same route length, pipe size, appliance count, permit allowance, and restoration scope.
Local labor and site logistics can outweigh small differences in pipe price.
Ways to lower the gas line quote without cutting corners
Keep the route direct and accessible where code and appliance placement allow. Installing a line during a kitchen, basement, or utility-room renovation can reduce later drywall removal and patching. Grouping multiple appliance connections into one scheduled project may also avoid repeat service-call minimums.
Request separate prices for the base line, trenching, wall repairs, and optional upgrades. Confirm whether the existing meter and regulator can handle the added load before approving replacements. Do not reduce pipe diameter or skip testing to save money; sizing and pressure checks are safety and code matters.
Control the route and project scope, but leave pipe sizing, permits, and pressure testing to qualified professionals.
Extra charges for permits, testing, and appliance connections
Permit costs commonly fall between $50 and $500, but some jurisdictions bundle inspection into the fee or charge separately. Pressure testing may be included in installation labor or appear as a $75-$250 service charge. Ask whether a utility shutoff or meter modification requires a separate appointment or fee.
Removing old pipe, relocating an appliance, repairing finishes, and connecting a new range or fireplace can each add cost. Appliance connectors and shutoff valves may be priced per fixture, while urgent or after-hours work can carry a higher service rate. A detailed written quote should identify which charges are included and which depend on inspection findings.
Verify the final price includes code-required testing and identifies any utility, permit, or restoration charges that remain outside the quote.
