How Mobile Handles Fence Regulations: A Practical Guide

Mobile maintains 125 local ordinances across all categories, and 3 of those deal specifically with fence regulations. Here is a breakdown of what the city actually requires, what is prohibited, and where Mobile falls on the strict-to-permissive spectrum compared to other cities.

Height Limits

Mobile limits residential fence heights to 4 feet in front yards and 6 feet in side and rear yards. Corner lots must maintain sight triangle visibility at intersections.

Key details: Front Yard: 4 feet maximum. Side/Rear Yard: 6 feet maximum. Corner Lots: Sight triangle required. Historic Districts: ARB review may apply.

Fences exceeding allowed heights without a variance face code enforcement.

Neighbor Fence Rules

Alabama does not require neighbor consent for fences on your own property. Mobile property owners must ensure fences are within their property lines. The finished side should face outward.

Key details: Neighbor Consent: Not required on own property. Property Line: Survey recommended. Disputes: Civil matter. Finished Side: Should face neighbor.

Encroachment is a civil matter. The city enforces code violations for height, materials, and setbacks.

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

Permit Requirements

Mobile generally does not require a building permit for standard residential fences under 6 feet. Fences over 6 feet, in flood zones, or historic districts may require permits or review.

Key details: Standard Fences: No permit under 6 feet. Over 6 Feet: Permit may be required. Historic Districts: ARB review required. Flood Zones: Additional requirements.

Fences requiring permits built without them may need modification. Historic district violations carry additional consequences.

Mobile is more permissive than most cities when it comes to permit requirements. That said, there are still limits.

The Bottom Line

Compared to many U.S. cities, Mobile gives residents more room on fence regulations. 2 of the 3 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.
