Start with jurisdiction and project scope
Before applying in Casper, confirm whether the property is within city limits or in unincorporated county territory. Describe the complete work to the office serving that parcel, including electrical, plumbing, structural, and site changes. Building, zoning, utility, and private HOA approvals can be separate.
Open the local official sources or prepare a project checklist.
Source availability audit: . This checks links, not every local rule. These compiled notes are starting points; confirm current dimensions, exemptions, fees, and adopted codes with the cited offices.
Building Permit Submittals
Casper building permits are required before new construction, remodeling, and additions, with different plan requirements for interior remodels, exterior additions, garages, and new residential construction.
Permit and scope questions
Casper says permits must be obtained before construction of a new building or remodeling or adding to an existing structure.
Zoning and placement
Even when a project does not require a building permit, other city requirements may apply, so Community Development should be contacted before work begins.
Building and trade review
Interior residential remodels may be reviewed with a simple plan, while exterior additions and garages require plot plans and construction details, and new residential work requires plot and structural plans.
Discuss your project early when: Call before applying if the project is an exterior addition, garage, new residential structure, remodel with structural changes, or if permit exemption is uncertain.

Fence and Accessory Building Permits
Casper requires fence permits for fences six feet or less and building permits for fences over six feet, walls over four feet, and accessory buildings 120 square feet or larger.
Source review: . Only the accessory-building size/exemption passage and its accompanying call-before guidance were rechecked against Casper's current permit-information page on September 26, 2026.
Permit and scope questions
For Casper, ask the permit office to confirm the height or depth limit and the grade or reference point used for measurement and the fence material, yard location and visibility restrictions before treating this project as exempt or permit-required.
Zoning and placement
Ask Casper's planning or zoning office to check the fence material, yard location and visibility restrictions and the setbacks, easements and public-space constraints for the parcel for the proposed site and use.
Building and trade review
Casper's current permit-information page exempts qualifying one-story unheated detached sheds below 120 square feet from a building permit, but still requires its free Fence/Shed permit. Other uses, dimensions and project conditions need review.
Discuss your project early when: Confirm the structure's exterior dimensions, heating, use and placement with Casper before relying on the shed exemption; review fence placement separately.

Building and Trade Inspections
Casper inspections are required before work is covered, including building, electrical, mechanical, and plumbing rough-in and final inspection stages.
Permit and scope questions
Casper states that all construction requires inspections before it is covered up.
Zoning and placement
Inspection planning should match the approved scope, plot plan, and permit conditions so work is not covered before required review.
Building and trade review
Building inspections can include rebar, footing and foundations, under-floor or slab, rough frame, insulation, drywall, final, or certificate of occupancy inspections.
Discuss your project early when: Call before covering footing, framing, insulation, drywall, electrical, mechanical, plumbing, gas, water, sewer, or slab work.
