What affects the cost?
- Tank size — a small 120-gallon tank runs $350-$900 installed, while a 1,000-gallon whole-home tank costs $1,500-$5,500 (Angi, HomeAdvisor, Fixr, HomeGuide)
- Aboveground vs. underground — aboveground tanks cost $400-$3,500 installed, versus $1,500-$5,500 for a buried tank, which needs excavation, trenching, and corrosion protection (Angi, HomeAdvisor); Fixr and HomeGuide put underground at $1,500-$5,000
- Buy vs. lease — buying a 500-gallon tank runs $1,000-$2,000 upfront, while leasing runs $150-$180 a year, though leases often carry minimum-usage fees (Angi, This Old House)
- Excavation and trenching for buried tanks — $500-$2,400 for excavation plus $400-$1,200 per 100 linear feet of trenching (Angi); HomeGuide cites $100-$300 per hour for an excavator and operator instead
- Gas line run from the tank to the house — $250-$800 (average $540), or $15-$25 per linear foot (Angi, This Old House); HomeGuide cites $15-$50+ per linear foot for materials and labor
- Permits and setback compliance — permits run $25-$150, and code typically requires an aboveground tank to sit at least 10 feet from an ignition source and 3 feet from any building opening (Angi, HomeAdvisor, This Old House)
- Concrete pad for aboveground tanks — $50-$175 total, or $5-$10 per square foot (Angi, HomeGuide)
- Labor and site conditions — installation labor runs $250-$5,000 depending on tank size and access, with plumbing labor billed at $45-$200 per hour (Angi, HomeAdvisor, This Old House)
Why does propane tank installation cost so much?
Propane tank pricing comes down to two decisions: how big a tank you need, and whether it sits aboveground or underground. Most homeowners pay $600 to $2,500 for the full installation, averaging around $1,400 nationally (Angi, HomeAdvisor, This Old House). By size, a 120-gallon tank — enough for a single appliance like a water heater — runs $350 to $900 installed, a mid-size 250-gallon tank runs $450 to $1,200, a 500-gallon tank for a whole-house system runs $700 to $3,000, and a 1,000-gallon tank for a larger home tops out at $1,500 to $5,500 (Angi, HomeAdvisor, Fixr, HomeGuide). Fixr’s own overall average lands notably higher at $2,500, which its size-by-size breakdown suggests reflects a mix weighted toward bigger tanks and underground installs rather than a small single-appliance hookup.
How much more does an underground tank cost than an aboveground one?
Burying the tank typically adds well over $1,000 to the job. Aboveground tanks cost $400 to $3,500 installed, while underground/buried tanks run $1,500 to $5,500 (Angi, HomeAdvisor) — Angi puts the gap at $1,100 to $4,700 more for going underground. The difference comes from site work: excavation runs $500 to $2,400, trenching adds $400 to $1,200 per 100 linear feet, and plumbing labor for the buried gas line runs $45 to $200 per hour (Angi, HomeAdvisor). Placement is also governed by fire code, not just preference. Brian Russo, a propane supplier featured on This Old House, explains that “one of the codes requires [aboveground tanks] to be 10 feet from any source of ignition.” A separate rule keeps the tank at least three feet from any building opening. Permits, which factor in these setback rules, cost $25 to $150 (Angi, HomeAdvisor, This Old House), and most jurisdictions require them before a tank goes in the ground or against the house.
Should I buy or lease my propane tank?
Buying costs more upfront but usually pays off if you’re staying put. A 500-gallon tank costs $1,000 to $2,000 to purchase outright, and owning it means you can shop around for the best per-gallon propane price and, in many cases, bury the tank to keep your yard looking clean (Angi, This Old House). Leasing avoids that upfront cost — expect to pay $150 to $180 a year plus the cost of fuel — and the supplier typically handles maintenance and inspections. The tradeoff is that leased tanks usually lock you into that supplier’s pricing, and many lease agreements include minimum-usage fees that can erase the savings if you don’t use much propane (Angi, This Old House). If you won’t be in the home long, leasing keeps upfront costs low; if you’re settled in for years, buying is usually the better math.
How to lower your propane tank installation cost
- Choose an aboveground tank over a buried one unless you specifically want the yard cleared — aboveground installs run $400 to $3,500 versus $1,500 to $5,500 underground (Angi, HomeAdvisor).
- Pick the smallest tank that meets your household’s needs. Jumping from a 250-gallon to a 500-gallon tank can add well over $1,000 to the installed cost (Angi, HomeAdvisor).
- Keep the gas line run short. Since it’s priced at $15 to $25 per linear foot, placing the tank closer to the house cuts that line item directly (Angi, This Old House).
- Compare buying versus leasing before committing, especially if you plan to stay in the home for many years — ownership avoids minimum-usage fees and long-term markups (Angi, This Old House).
- Confirm permit and setback requirements with your local building department up front, since fines or a forced relocation cost far more than the $25 to $150 permit itself (Angi, HomeAdvisor, This Old House).
Prices vary by region, tank size, and site conditions, so treat the figures above as a planning budget. Get two or three local quotes, and confirm upfront whether the concrete pad, gas line run, permits, and old-tank removal are included.

Angi, HomeAdvisor, and This Old House cluster tightly on the whole-project figure: average $1,400, typical range $600-$2,500. Angi and HomeAdvisor are sister brands under the same parent company and publish near-identical tables, and This Old House states it also draws in part on Angi's data for this guide, so these three aren't three fully independent confirmations. Fixr and HomeGuide, which describe different data-collection methods, corroborate the same order of magnitude and the same aboveground/underground and size-based cost structure, though Fixr's own overall average reads notably higher ($2,500, range $1,500-$3,750) — its per-size table shows that average is weighted more toward larger tanks and underground installs than a typical single aboveground hookup. national_average_usd and range_low_usd/range_high_usd are anchored to the Angi/HomeAdvisor/This Old House cluster. project_low_usd/project_high_usd ($350-$5,500) capture Angi's and HomeAdvisor's stated absolute low and high ends, covering everything from a small tank with no labor up to a large buried 1,000-gallon system. by_type rows use the widest low-high span any of the four sources cites per tank size, since sources differ on whether a given size is quoted aboveground-only, underground-only, or both. Figures generally cover the tank and standard installation; propane fuel itself, delivery fees, and ongoing rental/lease fees are priced separately and broken out in cost_factors rather than folded into the size-based figures.
