Tips

  • Any future use of an AG Exempt structure that does not qualify as agricultural use is a violation of the Canyon County Building Code Ordinance and may trigger code enforcement action.
  • This exemption is only for structures on parcels that are (1) zoned agricultural, (2) 5 acres or more, AND (3) receiving an agricultural tax exemption — all three conditions must be met.
  • HVAC, electrical, and plumbing in AG Exempt structures are handled by DOPL/DBS if installed.
  • Unlike standard building permits, the AG Exempt application is reviewed for zoning compliance only — there is no formal building plan review or inspection sequence (other than eligibility verification and future compliance checks).
