Code Notes
- Cheyenne routes plumbing, mechanical, and electrical permit applications through Building Safety. Its current-linked Schedule of Fees charges $23.50 through $500 valuation; $23.50 plus $3.05 per $100 or fraction from $501 through $2,000; and $69.25 plus $14 per $1,000 or fraction from $2,001 through $25,000, with higher published bands. The authority must determine valuation and required permits. This is a Cheyenne planning example, not a statewide Wyoming fee.
