Tips
- The City of Twin Falls Building Safety Department issues and inspects electrical permits directly within city limits; this is separate from Idaho DOPL's statewide contractor licensing/registration function.
- Mechanical plan review (where plans are required, e.g., commercial HVAC) takes 3 weeks per the City's published review timelines; simple trade permits without plan review are not subject to that timeline.
- To request an inspection, call the Electrical Inspection line at (208) 735-7235 or schedule via the CityWorks portal by 7:00 AM for same-day service.
Frequently asked questions
- Does the City of Twin Falls or the State of Idaho issue electrical permits?
- The City of Twin Falls Building Safety Department issues and inspects electrical permits within city limits under its own MEP Permit Application and fee schedule. Idaho DOPL separately registers/licenses electrical contractors statewide but is not the issuing authority inside Twin Falls city limits.
