Tips

  • Salmon has its own codified building-permit ordinance (City Code Chapter 151), but uses a shared 'Lemhi County and City Building Department' with the county for intake, plan review, and inspections — apply using the City of Salmon-specific application form, not the county form.
  • Both the City of Salmon and Lemhi County permit applications direct fee payment to 'Lemhi County' — no separate city-only fee schedule was found; the same Exhibit A valuation table applies to both.
  • Frost depth is 36 inches in the Salmon/Lemhi County design criteria table — deeper than many other Idaho jurisdictions (e.g., Boise's 24 inches).
  • Ground Snow Load is not a fixed local value — applicants must look it up via ascehazardtool.org and ensure the truss package matches.
  • Failure to call for required inspections is a violation: 1st offense $100, 2nd offense $250, 3rd offense $500, 4th offense is a misdemeanor.
  • Electrical, plumbing, and HVAC/mechanical permits are NOT issued by this department — contact Idaho DOPL at (208) 334-3233 / dopl.idaho.gov directly.
  • No published review-timeline SLA exists for this jurisdiction; call ahead to set expectations on plan review duration.
