Fence Regulations in Fort Smith, AR: What Residents Actually Need to Know

If you live in Fort Smith or are thinking about moving there, fence regulations are one of those things you probably won't think about until they affect you directly. Fort Smith has 5 specific rules on the books covering different aspects of fence regulations, and some of them might surprise you.

Permit Requirements

Fort Smith requires a building permit for any fence taller than 6 feet, issued by the Building Safety Division at 623 Garrison Avenue. Shorter fences must still comply with the height, material, setback, and corner sight-triangle rules in Chapter 27 of the Unified Development Ordinance.

Key details: Permit Trigger: Over 6 feet in height. Permit Office: Building Safety, 623 Garrison. Building Phone: (479) 784-1051. Zoning Phone: (479) 784-2216. Code Reference: Ch. 6 & Ch. 27.

Erecting a fence over 6 feet without a permit, or any fence that violates Chapter 27 height, material, or sight-distance rules, is a code violation. Building Safety may issue stop-work orders, citations, and orders to modify or remove the fence.

Height Limits

Fort Smith's Unified Development Ordinance (Chapter 27, including Article 27-700 General Standards and Article 27-400 Zoning Districts) generally caps residential front-yard fences at 4 feet and side and rear-yard fences at 6 feet, with up to 8 feet allowed in some districts. Fences over 6 feet require a building permit.

Key details: Front Yard Max: 4 feet (typical). Side/Rear Max: 6 feet (typical). Permit Trigger: Over 6 feet. Code Reference: Ch. 27 UDO (Art. 27-400/700). Sight Triangle: Required at corners.

Building a fence over the 4-foot front-yard cap, the 6-foot side/rear cap, or the district maximum violates Chapter 27. The Building Safety Division can issue a stop-work order, require an after-the-fact permit, or order the fence shortened or removed.

Approved Materials

Fort Smith's Chapter 27 UDO lists allowed residential fence materials (wood, metal tubing, wrought iron, stone, masonry, chain link, and listed vinyl/composite) and prohibits rope, wire fabric, barbed wire, chicken wire, tarps, sheet metal, plywood, and other improvised materials in residential zones.

Key details: Allowed Residential: Wood, metal, stone, chain link. Vinyl/Composite: Only if listed for fencing. Prohibited: Barbed wire, chicken wire, tarps. Prohibited: Sheet metal, plywood, plastic. Code Reference: Ch. 27 UDO.

Using prohibited materials (barbed wire, chicken wire, tarps, plywood, sheet metal, etc.) on a residential lot is a Chapter 27 violation. The Zoning Officer can order replacement, and Building Safety may issue citations or stop-work orders.

Neighbor Fence Rules

Fort Smith's Chapter 27 UDO does not require neighbor consent to build a fence; the owner only needs to stay on their own property and meet the city's height and material rules. Boundary and cost-sharing disputes are resolved under Arkansas partition-fence law (A.C.A. 18-11-101 et seq.) and Arkansas common law of boundaries.

Key details: Consent Required: No (city code). State Statute: A.C.A. 18-11-101 et seq.. Disputes Forum: Sebastian County Circuit Court. Best Practice: Boundary survey first. Property Line: Up to but not over.

Building a fence over the property line is not enforced by the city but creates private trespass and ejectment exposure under Arkansas common law. Misstating the property line on a permit application can void the permit.

If you are coming from a city with tighter rules, you will find Fort Smith gives residents more flexibility on neighbor fence rules.

Pool Barriers

Swimming pools in Fort Smith must comply with the 2021 International Residential Code (Appendix G) and the Arkansas Pool Safety Act (A.C.A. 20-26-301 et seq.). Barriers must be at least 48 inches high with self-closing, self-latching gates and no openings allowing a 4-inch sphere.

Key details: Min Barrier Height: 48 inches. Code Reference: 2021 IRC App. G. State Law: A.C.A. 20-26-301 et seq.. Federal Law: VGB Act (15 U.S.C. 8003). Gate Hardware: Self-close, self-latch, outward.

An unenclosed pool over 24 inches deep, a barrier under 48 inches, or a gate without self-closing/self-latching hardware violates the IRC as adopted and Arkansas state law. Building Safety can order the pool drained, issue citations, and the owner faces attractive-nuisance civil liability.

Compared to other cities, Fort Smith takes a harder line on pool barriers. The enforcement and penalty structure reflects that.

The Bottom Line

Fort Smith'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 Fort Smith is broadly strict or permissive.

These rules come from Fort Smith's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
