How Mobile Handles Fence Regulations: A Practical Guide
Mobile maintains 119 local ordinances across all categories, and 5 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.
Fence Permit Requirements
Mobile requires a permit for every fence or wall built in the city, per the Sec. 11-34 fee schedule: $5 if no inspection is required, $25 if inspection is required. Fences are not on the code's exempt-work list, and failing to get a permit multiplies the fee up to five times on a repeat offense.
Key details: Permit fee, no inspection: $5.00 per fence or wall. Permit fee, with inspection: $25.00 per fence or wall. Permit exemption: Fences are not on the exempt-work list. 1st offense penalty: 2x the required permit fee. 4th offense penalty: 5x the required permit fee.
Building or altering a fence without the required Sec. 11-34 permit is a violation under Sec. 11-33, punishable under chapter 1 of the Mobile City Code's general penalty provisions. Sec. 11-34(2)(w) adds a fee penalty on top of that: a first offense doubles the required permit fee, a second offense triples it, a third quadruples it, and a fourth or later offense multiplies the fee by five.
Retaining Walls
Mobile exempts retaining walls of 4 feet or less from a building permit: taller walls, or any wall holding back a surcharge or hazardous liquids, need one.
Key details: Exempt height: 4 ft or less, footing to top. Permit required: over 4 ft, or holding a surcharge. Also triggers permit: impounding Class I, II or III-A liquids. Governing section: Mobile City Code § 11-34.
Violating a permit requirement under this chapter is punishable under Mobile City Code chapter 1's general penalty provisions, per Sec. 11-33.
Height Limits
Mobile caps sight-obstructing fences at 3 feet in a required front or corner-lot side yard, and allows up to 8 feet everywhere else.
Key details: Front yard fence cap: 3 feet, sight-obstructing. Beyond front yard: up to 8 feet. Historic districts: separate design review limits apply. Corner lot side yard: 3 feet, sight-obstructing.
Fences and walls fall under the fence/wall permit and inspection fee in Sec. 11-34; general code violations are penalized under Mobile City Code chapter 1.
Neighbor Fence Rules
Adjoining property owners in Mobile must split the cost of building and repairing a shared partition fence or wall, unless they privately agree otherwise. If neighbors cannot agree, either owner may have the fence or wall built or repaired, and the director of inspection services can order repairs and require an equitable division of the expense between them.
Key details: Cost split: Joint expense between adjacent owners, Sec. 21-3. No agreement: Either owner may have fence built or repaired. Director authority: Can order repair and divide the cost, Sec. 21-2. Dispute panel: Municipal court appoints 3 freeholder inspectors. Payment deadline: 10 days after judge's order, Sec. 21-5.
Refusing to pay a director-ordered repair share under Sec. 21-2, or ignoring a municipal court payment order under Sec. 21-5, is punished as provided in Chapter 1, Article II: a fine up to five hundred dollars, up to six months' hard labor for the city, or both under Sec. 1-21, with each day of continued nonpayment counted as a separate offense. The inspector fee itself, two dollars per inspector, is fixed by Sec. 21-5 and comes on top of any fine.
Material Restrictions
Mobile prohibits barbed wire or other unsafe fencing material along or adjacent to any building line, with a narrow carve-out for fencing around city-owned public property.
Key details: Material banned: Barbed wire, unsafe materials. Where banned: Along/adjacent to building line. Who decides "unsafe": Director of inspection services. Exception: Public property, police chief request.
Violating the barbed-wire ban is an ordinance offense under Sec. 1-21: a fine up to $500 and up to six months' imprisonment or hard labor, with each day of a continuing violation a separate offense.
This is one of the stricter rules in Mobile's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
The Bottom Line
Mobile'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 Mobile is broadly strict or permissive.
