Gas Line Installation Cost in Orange County
A gas line prices as its own project in two units: by the linear foot, and by the whole run. Angi 2026 reporting puts professional installation at $260 to $820 for most projects, averaging $540. HomeGuide totals a run at $350 to $2,000 on the pages where it publishes a line price. This hub prices the line itself, frame by frame.

Two published frames, named apart and never blended
| Frame | What it prices | 2026 band |
|---|---|---|
| Angi frame | professional installation, most projects | $260-$820 |
| Angi frame | full range / average | $120-$1,350 / $540 |
| Angi frame | per linear foot | $15-$25 |
| Angi frame | permit fees | $100-$300 |
| HomeGuide frame | per linear foot (fireplace, propane pages) | $15-$50+ |
| HomeGuide frame | total run, on average | $350-$2,000 |
| HomeGuide frame | trenching, per linear foot | $5-$12 |
Neither frame is folded into the other. The Angi page, updated August 3, 2026, prices the project whole, then splits out per-foot and permit bands, and names trenching and restoration as underground adders. The HomeGuide frame is that publisher's line as published on its gas-fireplace and propane-tank pages. The run priced by end use sits on the gas line installation cost guide; the two scopes sit on the extension vs. new line guide.
Per-foot and per-run: two readings of one quote
A per-foot band prices length; a per-run total prices the whole job. Angi: $15 to $25 per foot against $260 to $820 for most projects. HomeGuide: $15 to $50 or more per foot against $350 to $2,000 on average. A short interior run can total under a long underground run at the same band, because the total also carries the route and any trenching it names.
Component pricing inside other projects, differentiated head-on
The line already appears across this site as component pricing inside other projects: named sections and budget lines that price a run only as far as another appliance or feature demands it. The fire pit hub carries a per-foot section inside the pit project. The venting guide prices a hookup table inside the venting project. The dryer guide prices a new line at $260 to $800 inside a dryer table. The outdoor kitchen hub prices a run at $500 to $2,000 inside the kitchen project, the generator hub an extension at $1,000 to $3,500 inside the generator project, and the pool heater guide a tie-in at $500 to $2,500 inside the heater project. Those pages price a line only as far as another appliance or feature demands it; this cluster prices the line itself, by the foot and by the run, whichever end use it feeds.
Reported scope and permit context, as reported only
Published reporting describes the quoted scope as priced lines, carried here as cost lines only: a pipe run line, a connection line, a pressure-test line, and a permit line where the project carries one. No line here describes a procedure of any kind. Permit context is likewise reported context only: reporting places gas work in permit and licensed-professional territory, and the Angi frame prices permit fees at $100 to $300. That is reporting, not advice on whether any specific property needs a permit; those calls belong to the local building department.
