For permitted fences built without custom engineering, Larimer County sets prescriptive construction standards: 6x6 support posts at a maximum 6 feet on center and at least 3 feet deep, 2x6 horizontal rails at a maximum 24 inches on center, and a maximum 9-foot height.
When a fence needs a building permit, the county allows a prescriptive path so most homeowners avoid hiring an engineer. Without engineering, the following apply: 6x6 support posts at 6 feet maximum on center, set at least 3 feet deep using preservative-treated or decay-resistant wood; 2x6 horizontal support rails at 24 inches maximum on center; and a maximum 9-foot fence height. Any fence design that falls outside these prescriptive rules requires plans stamped and sealed by a licensed Colorado professional engineer. Fences accessory to commercial uses must first be reviewed by Planning staff with engineer-stamped plans, and the local fire department may add requirements.
A permitted fence that deviates from the prescriptive standards without stamped engineering can fail inspection and require redesign or re-permitting.
