Assumptions

Calculated from 2 fee rules in effect on 2026-09-28.
Amounts are rounded to the nearest cent, once, at the end of each component.

Band $2,001-$100,000: $150.00 for the first $2,000 + ($30,000 − $2,000) ÷ $1,000 = 28 steps × $10.00 = $280.00. Permit = $430.00. Total: $430.00.

What is different in Casper

Plumbing work files with the Building Inspection Division under the combined Community Development schedule — the same valuation table as building, electrical and mechanical, driven by the scope's materials-and-labor value. Water heater and furnace replacements carry their $40 flat rows instead of the ladder. Sewer and water connection permits price at $35 initially. Re-inspections are $75 once an inspection has failed more than twice.

What this figure does not include

Impact fees, utility connections and other departments’ permits are the usual omissions, and in some jurisdictions they are larger than the permit fee itself.

Not included in these figures

This estimate covers the plumbing permit only. It excludes:

City of Casper water and sewer connection charges beyond the $35 permit rows.
Plan check at 25%/35% over $25,000 valuation.
Backflow and cross-connection program fees.
Contractor licensing.
Re-inspections beyond two ($75 each).
