Casper Building Department | Permits, Inspections & Contact

The City of Casper Community Development Building Department is the building-permit and inspection authority for work within Casper city limits. The department’s responsibilities include plan review, building inspections, contractor licensing, and enforcement of city building and zoning requirements. Natrona County or another municipality may be the authority outside the city, so verify the project address before starting an application.

How to apply for a Casper building permit

Casper uses an EnerGov Citizen Self Service portal. Register for an account, select Apply, choose the permit type, add the exact project address, describe the work and valuation, identify the owner and contractor, and upload plans, drawings, soils information, or other required attachments. Casper’s official application guide warns that address formatting matters when searching for a location in the portal.

The same EnerGov account is used to apply for permits, schedule inspections, and apply for or renew contractor licenses. Use the portal’s search and dashboard tools to review application history and status. If a project involves a site plan, zoning clearance, excavation, curb cut, or utility work, confirm those additional approvals with Community Development or Engineering before relying on the building permit alone.

Casper inspections and certificate of occupancy

Request inspections from the EnerGov account after the permit has been issued and the relevant stage of work is complete. Keep the permit, approved plan set, and inspection information accessible at the site. Required inspection types depend on the project and may include foundation, framing, insulation, trade, life-safety, and final inspections.

Casper’s building reports document temporary and final occupancy work on active projects. A certificate of occupancy or temporary certificate of occupancy is a separate completion milestone for projects that require it; contact the Building Department about the exact occupancy documentation for the building use before opening or occupying the space.

Casper zoning and plan review

Casper’s zoning process can affect the permit path. The city’s code requires zoning clearance or related development review before certain building or occupancy permits are issued. Confirm zoning district, use, setbacks, parking, landscaping, access, and site-plan conditions with Planning before submitting a complex commercial, multifamily, change-of-use, or addition project.
