Tips

  • Call the Building Inspector at 208.382.4279 before starting any project if you're unsure whether a permit is required.
  • A job copy of approved plans must remain on site at all times and be available to the inspector.
  • Post the permit card and house numbers visibly from the road before any inspection, including for new construction.
  • 24-hour advance notice is required to schedule any inspection.
  • Clearly mark property lines before the excavation/soils inspection and again before the footing/holes inspection.
  • Electrical, plumbing, and HVAC work must pass State of Idaho (DOPL) inspection and sign-off before the City's final building inspection.
  • Frost depth is 24 inches minimum — footings for decks, additions, and new construction must extend below this depth.
  • Roof design must account for a 100 PSF snow load — one of the higher snow-load requirements in the Treasure Valley/Valley County region given Cascade's elevation and winter climate.
  • The Fire District Impact Fee ($2,891 residential) is collected by the City on behalf of the Cascade Rural Fire Protection District as part of the building permit process for new construction.
