What a Standby Generator Does
A whole house standby generator sits outside on a concrete pad, connected directly to your natural gas or propane supply. It runs on its own fuel line, so there is nothing to haul out of a garage, fill with gasoline, or plug in manually. When the utility loses power, the automatic transfer switch (ATS) starts the generator and restores your circuits in under 30 seconds.
This is different from a portable unit, which requires you to be home, run extension cords, and refuel on a schedule. For more on that trade-off, see portable generator as a short-term backup or review home standby generator options and sizing.
What the Installation Covers
A licensed installer handles the entire job from start to inspection:
- Load calculation to size the unit correctly for your home's electrical demand
- Permits and utility coordination, including electrical and gas permits and the required inspection
- Concrete pad poured or placed to manufacturer and local code specifications
- Gas or propane line run from your meter or tank to the generator
- Automatic transfer switch wired into your main panel so the changeover is fully automatic
- System test and owner walkthrough to confirm every circuit and show you how to operate the unit
If your panel or home wiring needs updating before the generator can connect cleanly, talk to your installer about whole-house rewiring at the same time.
What Affects the Cost
No two installations are priced the same. The main factors are:
- Generator size - more kilowatts means a higher unit price
- Fuel type - running a new gas line from the meter adds to labor and materials; a new propane tank adds a tank installation cost
- Transfer switch type - a full whole-home ATS costs more than a partial-load transfer switch
- Site conditions - how far the unit is from your panel and gas meter, whether a concrete pad already exists, and local setback requirements all affect the job scope
- Permits and inspections - fees vary by state and municipality
Two Things Most Homeowners Overlook
HOA rules and setback requirements. Many HOAs have covenants that dictate where a generator can be placed, how it must be screened, and how loud it can be at the property line. Your installer knows local building codes, but HOA rules are separate. Confirm placement approval in writing before equipment is ordered, or you may face costly relocation after the pour.
Homeowner's insurance discounts. A permitted, permanently installed standby generator can qualify your home for a reduced insurance premium. Some carriers treat it as a risk-mitigation upgrade, similar to a security system or storm shutters. Ask your insurance agent about a discount before you finalize the purchase, not afterward.
Sizing Guide by Home Size
| Home Size | Recommended Range | Typical Loads |
|---|---|---|
| Under 1,500 sq ft | 10-14 kW | Lights, refrigerator, HVAC, well pump |
| 1,500-3,000 sq ft | 16-22 kW | Full HVAC, appliances, home office circuits |
| Over 3,000 sq ft | 24-26+ kW | Full home load, well pump, medical equipment |
If you plan to add a Level 2 charger, make sure the generator is sized to carry that load too. See EV outlet installation for what that circuit requires.
FAQ
How much does whole house generator installation cost?
Total cost depends on unit size, fuel type, transfer switch, labor, and permits. An in-home estimate after a load calculation gives you the only accurate number.
What size generator do I need for a whole house?
Most homes need 16 to 22 kW. Small homes can run on 10 to 14 kW; large homes with heavy loads need 24 kW or more. A licensed electrician does a load calculation to confirm.
Do I need a permit to install a whole house generator?
Yes, in nearly every municipality. A licensed installer pulls the electrical and gas permits and schedules the required inspection.
How does a whole house generator work?
The automatic transfer switch monitors utility power continuously. When the grid fails, the switch starts the generator and restores power in under 30 seconds with no action from you.
Can I install a whole house generator myself?
No. High-voltage panel work, a gas line, and a permitted ATS installation all require a licensed electrician and gas contractor. DIY installation voids the warranty and violates most local codes.

FAQ & Troubleshooting Nodes
Q:How much does whole house generator installation cost?
Total cost depends on the generator's size in kilowatts, fuel type, transfer switch type, labor, concrete pad, and local permit fees. There is no single number because every home's electrical load and site conditions differ. An in-home estimate after a load calculation gives you an accurate figure.
Q:What size generator do I need for a whole house?
Most homes fall in the 16 to 22 kW range. Small homes under 1,500 sq ft can run on 10 to 14 kW; homes over 3,000 sq ft with central HVAC, a well pump, or medical equipment typically need 24 kW or more. A licensed electrician does a load calculation to confirm the right size.
Q:Do I need a permit to install a whole house generator?
Yes, in nearly every municipality. The work involves a high-voltage panel connection, a gas or propane line, and an automatic transfer switch, all of which require permits and inspection. A licensed installer pulls those permits as part of the job.
Q:How does a whole house generator work?
A standby generator monitors utility power continuously from outside your home. When the power goes out, the automatic transfer switch (ATS) disconnects your home from the utility grid and starts the generator within 10 to 30 seconds, restoring power without any action from you.
Q:Can I install a whole house generator myself?
No. The work involves high-voltage electrical panel connections, a permitted gas or propane line, and ATS wiring. Doing it without a licensed electrician and gas contractor violates most local codes and voids the unit's warranty.
