Casper Wyoming Fence and Accessory Building Permit Guide

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.

Permit takeaway

Casper says a fence permit is required for any fence six feet tall or less that is erected, altered, or repaired, while fences over six feet and walls over four feet need building permits.

Zoning and placement

Front-yard residential fences may not exceed four feet, and fence or wall placement must account for corner sight-distance triangles and zoning setbacks.

Building and trade review

Accessory buildings 120 square feet and larger require building permits, while one-story detached accessory buildings under 120 square feet require a no-fee fence/accessory building permit.

Call before applying if the fence is in a front yard, on a corner lot, over six feet, a wall is near four feet, or a shed or accessory building is near 120 square feet.
