Deck Permit in Unincorporated Campbell County, Wyoming

Deck construction in unincorporated Campbell County is exempt from a Building Permit if small and detached (a Zoning/site-plan review is still required in most instances); larger or attached decks require a full Building/Zoning permit under the currently adopted IRC. The county's dedicated deck guideline still references the 2018 IRC and has not yet been reissued for the 2024 edition — treat its specific span/footing tables as a baseline reference, not a substitute for current 2024 IRC deck provisions.

Tips

  • A small (≤200 sq. ft.), low (≤30 in. above grade), detached deck not serving the main exit door needs NO building permit — but a zoning permit is required in most instances, so call (307) 682-1970 to confirm before starting.
  • The county's published deck guideline still cites the 2018 IRC by name even though Chapter 4 (June 2026) has since adopted the 2024 IRC countywide — use the guideline for general footing/guardrail technique, but confirm current dimensional requirements (span tables, guardrail heights) against the 2024 IRC directly for a permit-triggering deck.
  • There is no fee for a deck permit when one is required.
