Fence Regulations in Montgomery, AL

If you live in Montgomery or are thinking about moving there, fence regulations are one of those things you probably won't think about until they affect you directly. Montgomery has 3 specific rules on the books covering different aspects of fence regulations, and some of them might surprise you.

Retaining Walls

Montgomery, Alabama exempts retaining walls up to 4 feet tall, measured from the bottom of the footing, from a building permit. Anything taller, or any wall holding back a surcharge, needs a permit costing the greater of $75 or 0.25% of construction cost.

Key details: Permit-exempt height: Up to 4 feet, footing to top. Exemption void if: Wall supports a surcharge. Permit fee: 0.25% of cost, $75 minimum. Late-start penalty: 100% of permit fee. Governing chapter: City Code § 5-71(a) & (e).

Building a retaining wall over 4 feet, or one supporting a surcharge, without first obtaining the required permit exposes the property owner to a fee equal to 100% of the original permit fee on top of the permit cost itself, under the code's work-commencing-before-permit provisions, in addition to any correction the code official orders.

Material Restrictions

Within Montgomery, Alabama's SmartCode Sub-Urban (T3) Transect zones, the zoning code bars barbed wire and razor wire fencing on both residential and commercial lots. The city's older citywide barbed-wire and electric-fence law was repealed in 2024, so this SmartCode rule is now the only printed material ban in the code.

Key details: Banned materials: Barbed wire and razor wire. Where it applies: T3 Sub-Urban Transect (SmartCode) zones. Governing section: App. C, Sec. 10.14.2 SmartCode Art. 5.4.5(T3)(p). Old citywide ban: Repealed by Ord. No. 36-2024 (Aug. 20, 2024). Allowed T3 fence materials: Painted wood board, chain link, brick, stone, stucco.

Violations of the City Code, including the zoning ordinance in Appendix C, default to the general penalty in Sec. 1-6: a fine of not less than $1.00 nor more than $500.00, imprisonment in city jail for up to six months, hard labor for up to six months, or a combination. Each day a continuing violation persists is treated as a separate offense, and the city may also pursue injunctive or other equitable relief to abate it as a nuisance.

Height Limits

Montgomery caps fences and walls on office or residential lots at seven feet (eight feet in the R-20-t, R-24-t, PGH-35 and PGH-40 districts), dropping to three feet in any required front or street-side yard. Near street corners, sight-blocking fences between 3.5 and 15 feet tall are barred within 20 feet of the intersection.

Key details: General fence height cap: 7 feet. R-20-t/R-24-t/PGH-35/40 cap: 8 feet. Front/street-side yard cap: 3 feet. Corner visibility zone: Within 20 feet of intersection. Blocked height range at corners: 3.5 to 15 feet.

A fence or wall that exceeds the applicable height limit, or that blocks the corner sight triangle, violates the zoning ordinance and is punishable under Article II, Sec. 5 as provided in City Code § 1-6, with each day of the violation a separate offense. The administrative official or an affected neighboring property owner may seek an injunction or other court action under Article II, Sec. 6 to force a fence's removal or reduction.

The Bottom Line

Montgomery'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 Montgomery is broadly strict or permissive.
