Casper, WY Fence Regulations: Neighbor Fence Rules (2026)

Under Casper Municipal Code § 17.12.120(I), the city allows a residential landowner whose lot abuts a commercial, business, industrial or multi-family use to install a fencing 'buffer' along the common property line to improve compatibility between the two uses, but subsection I.1 puts the entire cost and expense of that buffer fence on the residential owner alone; the abutting commercial or industrial neighbor owes nothing toward it. The buffering fence may run the full length of the shared property line and must comply with the barbed-wire and electric-fence restrictions in subsection H, while the remaining sides of the residential lot still have to follow the ordinary fence rules in subsections A through G, including the eight-foot maximum height and the front-yard four-foot limit.

Building the buffer fence itself requires a valid fence/accessory building permit for anything up to six feet, and a full building permit for any section built higher than six feet, up to the section's overall eight-foot cap; the Community Development Department issues both permit types. Subsection I.4 also folds in every other Title 17 requirement that applies to the property's own zoning district, so a buffer fence cannot be used to sidestep district-specific standards elsewhere in the code. Because the ordinance singles out the residential side of the boundary, a resident cannot bill an adjoining business or industrial property owner, or split the cost with them, for a fence built under this specific buffering provision, even though the fence benefits both properties by screening the more intensive use.
