What is different in Casper
The Building Inspection Division, at 200 North David Street, issues building, electrical, plumbing and mechanical permits from one combined schedule — the valuation (all materials and labor) drives every trade. Permits run 180 days and renew at $60 or 10% of the original fee. Common replacements carry flat rows: $40 for a tank-style water heater or furnace swap, $70 for a mobile home set. After-the-fact permits double the fee, capped at $750. Demolitions run $200 residential / $300 commercial.
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 permit and, over $25,000 valuation, the plan check. It excludes:
- Erosion control permits ($50/acre plus bond) where applicable.
- Sewer and water connection permits ($35 initial rows).
- Planning/engineering reviews (plats, zone changes, site plans $600-$2,300).
- Contractor licensing.
- Re-inspections beyond two ($75 each).
What you need before applying
- Complete building permit application with valuationRequired
Permit fees base off the Community Development fee schedule against project valuation (all materials and labor); after-the-fact applications — construction started before review and approval — are assessed at double the building permit fee, not to exceed $750.00.
- 180-day permit validity and renewalMay be required
Once issued, a permit is good for 180 days; permits exceeding 180 days since the last inspection renew at $60 or 10% of the original permit fee, whichever is higher.
