Do I need a permit for standby generator installation in Columbia?
Yes. In South Carolina, standby generator installation generally requires a permit, and Columbia is no exception.
A standby generator has required clearances from windows, doors and the property line, and the fuel connection needs its own gas or mechanical permit. Confirm placement before the concrete pad goes in. In flood-prone coastal areas near Charleston, the generator and transfer equipment may need to sit above the flood elevation. Verify local flood requirements for the pad height. A permanently installed standby generator combines electrical and, for a gas unit, gas scopes, and Columbia issues both as Building Trade Permits. Generator placement must meet zoning setbacks and equipment clearances, which are reviewed separately from the trade permits.
