Tips

  • Demolition is one of the few permit types in Natrona County with its OWN flat fee ($75 residential/$150 commercial) rather than the general valuation table — do not apply the valuation schedule to a demolition permit.
  • Check with Wyoming DEQ's asbestos program (linked from the county's Adopted Building Codes page) before demolishing any structure that may contain asbestos-containing materials.
