How St. Louis Handles Fence Regulations: A Practical Guide

St. Louis maintains 204 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 St. Louis falls on the strict-to-permissive spectrum compared to other cities.

Neighbor Fence Rules

St. Louis does not mandate shared fence costs for urban residential property. Missouri RSMo 272.010 partition fence law applies only to agricultural land. The good-side-out tradition is customary but not legally required.

Key details: Cost Sharing: Not required urban. State Law: RSMo 272 agricultural only. Survey: Recommended. Good Side: Customary not required. Disputes: 22nd Circuit Court.

No city penalty for unilateral fence construction on your own side. Encroachments resolved in civil court.

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

Height Limits

St. Louis fence heights are capped at 4 feet in front yards and 7 feet in side and rear yards under SLRC 26.32.030 and the St. Louis Zoning Code. Historic districts like Lafayette Square, Soulard, and Compton Heights have additional design review.

Pool Barriers

St. Louis requires all residential pools with water deeper than 24 inches to be enclosed by a 48-inch minimum barrier under SLRC 25.60 and the 2018 IRC. Self-closing, self-latching gates with latches 54 inches high are mandatory.
