Tips

  • Homes manufactured before June 15, 1976 cannot receive a placement permit until a Mobile Home Compliance Rehabilitation Certificate is obtained from Idaho DOPL — plan for this extra step if buying an older unit.
  • The county Treasurer's Office must verify all property taxes are paid in full before the placement permit application is processed.
  • A Flood Plain Review by the Cassia Flood Plain Manager is a required line item specific to this permit type — confirm flood plain status before submitting.
  • A permanent foundation triggers an additional per-lineal-foot concrete fee on top of the base placement fee; contact the Building Department for the current rate.
