Fence Regulations in Greeley, CO

If you live in Greeley or are thinking about moving there, fence regulations are one of those things you probably won't think about until they affect you directly. Greeley has 4 specific rules on the books covering different aspects of fence regulations, and some of them might surprise you.

Material Restrictions

Greeley confines barbed wire to the I-M, I-H, C-D and H-A zoning districts and leaves it off the approved list for standard residential fences; electric fences are allowed citywide but need a building permit, warning signage, and an outer non-electric fence.

Key details: Barbed wire zones: I-M, I-H, C-D, H-A only. Electric fence permit: Required under § 22-96. Signage required: 'DANGER, ELECTRIC FENCE'. Noncompliance cure period: 60 days.

Installing an electric fence without a permit or required signage is a code infraction under § 24-104(c) and § 22-96 (R331.5): noncompliant fences get 60 days to correct or must be removed, on top of standard Title 1 fines.

Compared to other cities, Greeley takes a harder line on material restrictions. The enforcement and penalty structure reflects that.

Retaining Walls

In Greeley, any retaining wall over 4 feet requires a building permit: the same trigger point that applies to any fence or wall over 6 feet, with taller setback walls needing separate alternative-compliance approval.

Key details: Permit trigger: Over 4 feet. Measured from: Footing bottom to wall top. Fence permit trigger: Over 6 feet. Setback wall over 6 ft: Needs alternative compliance.

Building an unpermitted retaining wall over 4 feet is a code infraction under § 24-104(c): fines start at $100, climb to $250 for a second violation within 24 months and $500 for a third, plus possible correction or removal orders.

Fence Permit Requirements

Greeley requires a building permit for any fence or wall over six feet, or a retaining wall over four feet; walls above six feet in a setback need alternative-compliance approval.

Key details: Permit trigger: Fence or wall over 6 ft. Retaining wall trigger: Over 4 ft needs permit. Setback wall over 6 ft: Needs alternative compliance (§ 24-208). Under 6 ft: No building permit required.

Building a fence or wall over six feet (or a retaining wall over four feet) without a permit is a code violation that can trigger a stop-work order, fines, or forced removal.

Height Limits

Greeley caps front-yard fences at 3.5 feet, or up to 6 feet for 75%-open ornamental designs, while side and rear yard fences are allowed up to 6 feet under Municipal Code Table 24-5-5.

Key details: Front setback height: 3.5' standard, up to 8' ornamental. Side/rear height: 6' standard; taller behind building line. Governing table: Table 24-5-5, § 24-502.e. Code currency: Current through Supp. 6, April 2026.

Community Development can order removal or modification of an oversized or misplaced fence as a zoning violation, and building an over-six-foot fence without the required permit risks a stop-work order.

The Bottom Line

Greeley's fence regulations rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Greeley is broadly strict or permissive.

Keep in mind that Greeley can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
