Tips

  • Call 208-236-7090 to request an inspection. A permit must be issued and active before an inspection can be requested. A 24-hour notice is required; requests made after hours are processed the next business day. Inspections occur Monday–Thursday 8:00 AM–5:00 PM and Friday 8:00 AM–1:00 PM. Specific inspection times cannot be requested.
  • Electrical, plumbing, mechanical, and fuel-gas fixtures are NOT permitted or inspected by Bannock County. Contact the Idaho Division of Occupational and Professional Licenses (DOPL) at 1-800-955-3044 or dbs.idaho.gov.
  • Post-frame (pole barn) construction is common in unincorporated Bannock County; the County publishes a dedicated Post-Frame (Pole Barn) Guide as a design aid for prescriptive plan submittals.
  • Snow/roof live loads are elevation-dependent in Bannock County, ranging from 35 PSF roof live load / 44 PSF ground snow load below 4,600 feet up to 100 PSF roof live load / 125 PSF ground snow load above 6,800 feet.
  • Structures under 200 square feet and under 12 feet high used as a tool shed, playhouse, or similar accessory use, fences 7 feet or less, retaining walls 4 feet or less, playground equipment, detached decks under 200 square feet and less than 30 inches above grade, and swimming pools under 5,000 gallons and less than 48 inches deep do not require a building permit — but a zoning/development permit may still apply.
  • Habitable space, communication towers, and photovoltaic (solar) systems always require a building permit even if they would otherwise fall under a size exemption.
  • An address is typically issued at the same time as the first building permit for a property. Addresses are not assigned to agricultural-exempt buildings or structures under 200 square feet.
  • If the property is served by septic, contact Southeastern Idaho Public Health (208-239-5276) — a new system requires a permit, and adding bedrooms to a home on an existing system requires written approval.
