A whole-home generator in Jupiter costs $11,000–$17,000 installed and permitted, depending on the size of the generator, the fuel line, the concrete pad, the transfer switch, and the permit. The range is wide because the price isn’t the generator — it’s the site.
What a whole-home generator costs in Jupiter
The generator itself is the smallest part of the decision. The two most common whole-home sizes in the county are 22kW and 26kW. A 22kW generator — a Generac Guardian, for example — costs $5,500–$7,000. A 26kW generator — a Kohler 26RCA, for example — costs $7,000–$8,500. The difference isn’t the house size — it’s the air conditioning.

What the numbers leave out
The national average — $5,154, all-in — is 8 years out of date. It excludes the transfer switch, the fuel connection, the concrete pad and the permit, and it comes from a market where the housing stock is newer and the lots are bigger. And the price has been rising: generator installation costs have grown by 8.7% a year, on average, for the last decade. A national average tells you nothing about the price in Jupiter.
The three things that move the price most
- The air conditioning. A 22kW generator will run a 3-ton air conditioner. A 26kW generator will run a 4-ton air conditioner. The difference is the air conditioning — not the house size.
- The fuel line. If the gas meter is on the other side of the house, the fuel line is longer — and the cost goes up.
- The permit. The permit fee is a percentage of the job value, so a more expensive install means a more expensive permit.
What it costs to run
About $10 per hour, at $3.10 per gallon, running at half load.
The tank. The tank is the part most people forget. A 22kW generator running at half load uses about 3.2 gallons of propane per hour. A 500-gallon tank — the most common size in the county — will run it for about 6 days. The tank must be at least 5 feet from the house and 10 feet from any property line. The installer confirms the setback before the work starts.
The monitoring. And if you’re not in the house to hear it start, you need to know it started. That’s what remote monitoring does — it tells you the generator is running, and it tells you if it isn’t. Mobile Link is free for the first year, and $100 a year after that.
The permit
In Jupiter, the permit fee is 2% of the job value — 2% of $11,000 is $220, and 2% of $17,000 is $340. The permit is issued by the town’s Building Division, and the review typically takes up to 10 business days, though the state requires the town to act within 5 business days of a complete application (Florida Statute §553.792).
Not sure what size you’d need? The two most common whole-home sizes in the county are 22kW and 26kW — and the difference isn’t the house size, it’s the air conditioning.

Palm Beach Backup Power is an information and referral site. We publish the numbers, the rules, and the costs — and when the installer partner is in place, we refer you to a licensed installer for the work. We don’t install generators, and we don’t sell them. What we do is make the decision legible: what it costs, what the permit costs, what the fuel line costs, and what to ask before you sign.
