Tips
- Idaho City is a small municipality (Boise County seat, population roughly 485) — the Building Permits and Inspections Department can be reached directly at (208) 392-4584 for forms and scheduling.
- Separate state (DOPL) permits are required for electrical, plumbing, and mechanical/HVAC work — these are NOT issued by the City. Contact DOPL at (208) 334-3233 or dopl.idaho.gov.
- If your property is within the Historic District, get your Certificate of Appropriateness from the Historic Preservation Commission BEFORE applying for your building permit — the Commission meets only once a month (3rd Wednesday), so factor that into your timeline.
- Properties connecting to City water and/or sewer must pay $3,785.25 per connection type in full before the City will issue the building permit.
- A 'No Permit Required Items' list is available from the City covering minor work (small accessory structures under 200 sq ft, fences under 7 ft, low retaining walls, small decks, etc.) that does not require a permit — download it from the Building Permit Information page before assuming a permit is needed.
- The City's downloadable Building Permit Fee Schedule and application PDFs are labeled by fiscal/school year (e.g., '2025-26') and are updated periodically — always pull the current version from the City's site.
