How much does generator installation cost in Columbia?
In Columbia, a whole-house standby generator (18–26 kW) typically runs $10,000–$20,000 installed, including the transfer switch, gas connection, pad and permits. A smaller essentials-only unit (10–14 kW) runs $8,000–$13,000. A portable generator with an interlock kit is the budget option at $800–$2,000.
Do I need a permit for a generator in Columbia, SC?
Almost everywhere, yes. A standby generator needs an electrical permit and usually a gas/plumbing permit, and most states require the work be done by a licensed contractor. A reputable Columbia installer pulls the permit for you — treat anyone who offers to skip it as a red flag, since unpermitted work surfaces at resale and can void insurance claims.
Who installs generators in Columbia?
Licensed electricians and specialized generator dealers handle installation. A standby generator also needs a gas connection, so many jobs involve both an electrician and a plumbing contractor — dealers coordinate both.
