How Fort Collins Handles Fence Regulations: A Practical Guide

Fort Collins maintains 111 local ordinances across all categories, and 6 of those deal specifically with fence regulations. Here is a breakdown of what the city actually requires, what is prohibited, and where Fort Collins falls on the strict-to-permissive spectrum compared to other cities.

Neighbor Fence Rules

Colorado has no shared fence cost statute. Each property owner is responsible for their own fence. No equivalent to California’s Good Neighbor Fence Act.

Key details: Cost Sharing: No state requirement. Boundary: Agree with neighbor. Written Agreement: Recommended. HOA: May dictate fence type.

Civil dispute - no city enforcement for cost-sharing. Property line encroachments: survey and civil remedy. HOA violations per CC&Rs.

Fort Collins is more permissive than most cities when it comes to neighbor fence rules. That said, there are still limits.

Pool Barriers

Fort Collins requires pool barriers meeting safety codes to prevent drowning. Fences must be at least 4 to 5 feet tall with self-closing, self-latching gates.

Key details: Min Height: 48 to 60 inches. Gates: Self-closing, self-latching. Openings: Less than 4 inches. Enforcement: Inspection at permit.

Non-compliant barriers: immediate correction required. Fines $100 to $500. Pool use prohibited until barriers meet code. Liability exposure for accidents.

This is not one of those rules that cities tend to ignore. Fort Collins actively enforces its pool barriers requirements.
