Simpsonville's newer housing stock (Five Forks, Holly Tree) means cleaner panels and faster installs. Older Fairview homes sometimes need a main breaker upgrade first — we'll spot it on the quote visit.
Simpsonville permits run through City of Simpsonville's permit portal (evolve-public.infovisionsoftware.com). We pull under SC Electrical License 2942, stand for the inspection, close the job out. You don't visit city hall. You don't take a day off. We handle the entire paperwork cycle.
20–30 minutes from our base — we schedule Simpsonville work in batches so we get two or three installs in a single day. If you're over by Holly Tree, Five Forks, Woodruff Road, or the newer subdivisions out past Fairview, same-week install is typically available. Older homes sometimes need a panel upgrade first — we'll flag that in the quote, no surprises.
A standby whole-home generator (Generac, Kohler, Briggs) runs $12,000–$18,000 installed. It's automatic, it's wonderful, and it's overkill if you just want the lights, fridge, WiFi, and well pump through a storm. You've already got the portable generator. The inlet + interlock unlocks its full usefulness for a tenth the cost of a standby install.
Does my generator need a 240V outlet? Yes — either a 30A (three-prong twist lock) or 50A (four-prong). If yours is 120V-only, it's not compatible with this install.
How long until I'm scheduled? Typical turnaround in Simpsonville is 3–10 days from quote to install.
Do I need permission from Duke Energy? No. The interlock mechanically prevents backfeeding so the install is code-compliant and doesn't require utility approval.
Do you cover the unincorporated areas around Simpsonville? Yes — if your address is Simpsonville 29680 or 29681 and you're technically in Greenville County (not city limits), we pull the county permit instead of the city. Same price either way.
How busy is the Simpsonville permit office? Turnaround is usually 1–3 business days. Faster than Greenville County, slower than the City of Greenville.
