WHAT A WHOLE-HOUSE GENERATOR REALLY COSTS IN THE BAY AREA
Here's the number most contractors make you sit through a sales visit to hear: most Bay Area whole-home generator installations run $16,000 to $28,000, complete. That's the unit, concrete pad, automatic transfer switch, gas and electrical work, city permit, inspection, and startup — done by one licensed crew. Below is exactly where your project lands in that range, and why.
Installed pricing by system size
Keeps the core of the house alive through any outage. The right call for smaller homes and tighter budgets.
The most common Bay Area choice: the entire house runs, air conditioning included, and you stop thinking about outages entirely.
Quieter, continuous full-load power for properties that outrun standard residential units. Scoped on site, not from a menu.
Numbers reflect our real 2026 installed pricing on typical sites. Unusual gas runs, panel upgrades, or placement constraints move a project within — occasionally above — these ranges, and we tell you before anything is signed.
The five real cost drivers
⬢Generator size. A 28kW unit costs more than an 18kW — but oversizing "just in case" is the most common way homeowners overspend. We size from your actual panel loads. ⬢Gas supply. Larger units can need a PG&E meter upgrade. It adds cost and lead time, and we flag it on day one — never as a mid-project surprise. ⬢Your electrical panel. Older panels sometimes need an upgrade to accept a transfer switch. When they do, it folds into the same project and permit. ⬢Distance and placement. Feet of gas line and wire between the generator, the meter, and the panel are real materials and labor. ⬢Your city’s permit process. Every Bay Area city runs its own counter, fees, and inspection quirks — we file and manage all of it, from Pleasanton to Atherton."Complete" means complete

⬢Portable generator ($1k–$3k): works if you’re home, willing to wheel it out, run cords, and refuel in the rain — and it can’t legally power your whole panel without an installed transfer switch. Fine for camping; frustrating as a home plan. ⬢Battery backup ($13.5k+ per Powerwall): silent and instant, and we install those too — but batteries hold hours of whole-home power, not days. In multi-day PSPS country, batteries pair best WITH a generator rather than replacing one. ⬢Doing nothing ($0 up front): every outage costs food, comfort, work hours, and sometimes hotel nights — and fire-season shutoffs aren’t getting rarer. The do-nothing plan is the only one that charges you every single year.Financing is available through our partner Synchrony — many customers put a generator on monthly payments smaller than a car note.
Cost questions we hear most
Is a whole-house generator worth the cost?
If outages cost you spoiled food, missed work-from-home days, dead sump pumps or medical equipment, or evacuated refrigerators every fire season — a one-time $16k–$28k install that removes the problem for 15+ years usually pays for itself in avoided losses and home value. In PSPS-prone hills, it's increasingly a selling point.
Why do quotes range from $16,000 to $28,000?
The unit itself is only part of the price. The spread comes from generator size (22 vs 28kW), gas supply (a PG&E meter upgrade adds cost and time), your panel's age and capacity, distance between generator, gas, and panel, and your city's permit requirements. That's why we ballpark in 60 seconds online, then firm it up at your home.
Can I save money installing it myself or with a handyman?
Standby generators tie into your gas line and your electrical service — both legally require permits, and the utility work requires a licensed contractor. Unpermitted installs surface at insurance claims and home sales, and gas work done wrong is dangerous. This is a licensed-crew project, full stop.
What does it cost to run?
Very little in normal life: the weekly self-test costs pennies of gas. During an outage it burns natural gas or propane roughly like a large appliance — for most homes a long multi-day outage costs tens of dollars, not hundreds.
Do you offer financing?
Yes — through our partner Synchrony. Ask about monthly payments when you run your ballpark.
What about very large homes and estates?
Above 28kW we install Generac's liquid-cooled series (25–60kW) — quieter, built for continuous full-estate load. Those projects are scoped privately on site rather than priced from a menu.
