Tips

  • The $158-per-section fee applies per home section (e.g., a double-wide is billed as two sections).
  • Electrical and plumbing hookups for manufactured homes still require separate Idaho Division of Building Safety (DBS) permits and inspections, the same as site-built construction.
  • This permit uses the same general building-permit review process and timeline as other residential permits (Building Official's 30-day policy cap; typically a few days to a week per the county's Building FAQs).
