Casper, WY Fence Regulations: Fence Permit Requirements (2026)

Casper's zoning code treats every fence and wall as permit-triggering construction. Casper Municipal Code § 17.12.120(A) sets the baseline: no fence or wall may exceed eight feet in height anywhere in the city, except where the section itself allows a different number. Subsection B then makes the permit mandatory: "No fence or wall shall be constructed or modified unless the owner first obtains a fence permit from the community development department," and layers a full building permit on top for any fence taller than six feet or any wall taller than four feet, reflecting the added structural review those heights need.

Subsection C requires payment of a uniform fee, set by city council resolution, at the time the fence permit application is submitted; the fee schedule is not fixed in the chapter itself but is adopted separately by council action. Because the permit requirement attaches to any fence or wall that is "constructed or modified," repairs or height changes to an existing fence trigger the same review, not just new installations. The Community Development Department is the office that issues both the fence permit and, where required, the building permit, and the same department reviews the corner sight-triangle and front-setback height limits found elsewhere in § 17.12.120 as part of that review.

A homeowner who wants to build a privacy fence along a side yard, replace a deteriorated wood fence, or raise a fence above six feet should expect the permit step and the associated fee before starting work, since the code gives Community Development no discretion to waive the permit for ordinary residential fencing.
