What a Generac generator really costs installed in Florida: unit, transfer switch, fuel, permits. Full breakdown for Palm Beach & Brevard County.
Most homeowners in Palm Beach County and Brevard County start with the same question: how much does a Generac generator cost, fully installed? The unit price you see online is only part of the answer. What you actually pay depends on the generator size, the permit fees in your county, whether your home needs a panel upgrade, and the cost of the natural gas line or LP tank.
Here is a straight breakdown of what goes into the number.
Generac Unit Cost by Size
Generac Guardian home standby generators range from 10 kW to 24 kW for most residential applications.
10 kW — Handles essential circuits: one AC zone, refrigerator, lights, outlets, and a well pump or sump pump. Starting price around $3,000–$4,000 for the unit alone.
14–18 kW — Powers most Florida homes including two AC zones, all major appliances, and a pool pump. Unit cost roughly $4,500–$7,000.
22–24 kW — Full whole-home coverage for larger homes or homes with all-electric appliances. Unit cost $7,000–$10,000+.
These are equipment prices only. Florida installation adds significant cost on top.
What Installation Adds in Florida
Permits. In Florida, generator installations require a permit and final inspection. Palm Beach County, Brevard County, and their municipalities each have their own fee schedules. Permit costs typically run $150–$600 depending on jurisdiction and project scope.
Concrete pad. Every standby generator installs on a permanent concrete pad. Pad cost is usually $300–$600 depending on size and access.
Transfer switch. The automatic transfer switch connects the generator to your home's electrical system and isolates the home from the grid during an outage. Transfer switches add $500–$1,500 to the job.
Surge protector. Florida building code requires a whole-home surge protector with any generator installation that modifies the panel. This adds $200–$400.
Gas line. If your home does not have an existing natural gas line near the generator location, running new gas line is the largest variable cost. A short run from an existing meter is $300–$800. Running new gas service across the yard or from the street can reach $1,500–$3,000+.
Total Installed Cost Ranges in Florida
Putting it together, here is what most Palm Beach County and Brevard County homeowners pay for a complete Generac installation:
10–14 kW system, essential circuits: $5,000–$9,000
18–22 kW system, most of the home: $8,000–$13,000
24 kW+ whole-home system: $12,000–$18,000+
These ranges assume the home has an existing natural gas supply nearby and a panel in reasonable condition. If either of those is not true, the cost goes up.
What Pushes the Price Higher
Panel upgrade. If your home has a 100-amp panel, an older Federal Pacific or Zinsco panel, or a panel without space for a transfer switch breaker, it needs to be addressed before the generator can be safely connected. A panel upgrade in Florida typically runs $2,000–$4,500 and requires its own permit.
LP (propane) instead of natural gas. If natural gas is not available at your address, LP is the alternative. LP requires a propane tank, which is either leased from a propane supplier or purchased outright. Tank sizing, delivery coordination, and the regulator add cost versus a natural gas connection.
HOA requirements. Some HOAs in Palm Beach County and on the Space Coast require screening, specific pad locations, or aesthetic enclosures around the generator.
When Is the Right Time to Install?
The permit process in Palm Beach County and Brevard County typically takes two to four weeks under normal conditions. During peak season, especially after a named storm, permit queues extend and installation slots fill up quickly.
The right time to call is before hurricane season, not when a storm is in the forecast.
