Sebastian Pricing
What Does a Generator Cost in Sebastian?
Whole home installs in the Port Saint Lucie area typically run $7,000 to $25,000+. Here's where most Sebastian homes land.
Essential circuits (lights, fridge, AC unit)
Most homes under 3,000 sq ft (full house)
Larger homes, multiple HVAC zones
Large homes, home offices, medical equipment
Prices include equipment, in-house installation, transfer switch, permit fees, and our 12-year warranty on every Generac air-cooled unit we install. Where a Florida City Gas main runs past your Sebastian home, a natural gas connection typically adds minimal cost compared with a propane tank installation.
Because GenerX employs all labor in-house, we eliminate the third-party markup that drives up installation costs elsewhere. Our buying volume as Florida’s largest dealer means we get better equipment pricing than smaller dealers. The result: a higher-quality installation at a more competitive price, not a trade-off.

Frequently Asked Questions
Sebastian Generator Questions, Answered
What does Sebastian require for a generator permit?
The city’s Emergency Generator sheet asks for two surveys showing the generator and the gas line from the tank, an electrical permit with a gas sub permit, and electrical specifications with the disconnect. The unit sits at least 3 feet from the house and 5 feet from any opening. GenerX pulls the permit with a licensed electrician and schedules the inspections. You sign the Notice of Commencement.
Where is the Sebastian Building Department?
At 1225 Main Street. Applications go in through the MGO customer portal or by email, and an owner acting as builder has to apply in person. GenerX files as the licensed contractor, so you do not need to visit.
Can my Sebastian generator run on natural gas?
If Florida City Gas has a main on your street, yes; its tariff names Sebastian. Many Sebastian homes use propane instead, from a tank we place and permit with the generator.
What has knocked out power in Sebastian?
Hurricanes passing up the coast or across the state. Irma left about 80% of Indian River County’s accounts without power in 2017, and Milton cut 31,360 FPL customers in the county in 2024.
How fast can GenerX reach Sebastian for repairs?
Sebastian is covered from our nearest facility, with parts stocked at our local facility. Emergency service is 24/7, and in a widespread outage our statewide fleet moves up the Treasure Coast.
