Tips

  • Fire alarm permits in Natrona County are handled entirely separately from the county Building Department — apply and schedule all inspections through NCFPDpermits.com, not the county's ViewPointCloud portal.
  • The permit fee is priced by device count (FACP, FAAP, detectors, horn/strobes, beam detectors, etc.), not by job valuation — count your devices before applying to estimate the correct fee tier.
  • Starting work without a valid NCFPD construction permit doubles the fee for each fire protection system installed — this is separate from and in addition to the county Building Department's own triple-fee penalty for unpermitted building work.
