Apex's Fence Regulations: The Rules That Matter

Every city handles fence regulations a little differently. In Apex, North Carolina, there are 8 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Height Limits

Apex fence heights are set by Section 8.2.7 of the Town of Apex Unified Development Ordinance (UDO), administered by the Apex Planning Department. Section 8.2.7.B.1 caps freestanding fences and walls at 7 feet, including piers, posts, and finials. Section 8.2.7.B.2 limits fences and walls in front yards to 48 inches (4 feet), with piers/posts and finials allowed to extend up to 6 inches higher. Non-residential fences may exceed 7 feet with Planning Director approval for security or screening, and vinyl-coated chain link for single-family recreational uses such as tennis or basketball courts may be approved up to 10 feet.

Key details: Maximum Freestanding Fence Height: 7 feet (UDO Sec. 8.2.7.B.1). Front Yard Maximum: 48 inches / 4 feet (UDO Sec. 8.2.7.B.2). Post/Finial Extension: Up to 6 inches above the finished fence height (Sec. 8.2.7.B.2). Non-Residential Above 7 Feet: Planning Director approval required (Sec. 8.2.7.B.1). Recreational Court Fencing: Vinyl-coated chain link up to 10 feet with Planning Director approval.

A residential front-yard fence taller than 48 inches (other than the 6-inch post/finial extension) violates Sec. 8.2.7.B.2. A freestanding rear-yard fence or wall exceeding 7 feet without Planning Director approval violates Sec. 8.2.7.B.1. Recreational chain link courts over 10 feet, or built without Planning Director approval, are out of compliance. Enforcement is handled by the Town of Apex Planning Department and Building Inspections.

Neighbor Fence Rules

Apex regulates fence location, height, and finish under UDO Sec. 8.2.7 but does not impose a cost-sharing requirement on neighbors. Section 8.2.7.A.2 requires the finished side of a fence to face an adjacent property or public right-of-way, except in the Downtown Festival District where the side facing an alley may be unfinished. Per the Town's published FAQ, 'your fence can be placed up to, but not on or over your property line,' and Apex does not survey property lines or arbitrate private boundary disputes. Boundary, cost-sharing, and partition issues are private civil matters governed by North Carolina common law.

Key details: Finished-Side Rule: Required toward right-of-way / adjacent property (Sec. 8.2.7.A.2). Downtown Festival District Exception: Alley-facing side may be unfinished. Property Line Placement: Up to, but not on or over, the line (Apex Planning FAQ). Cost-Sharing Mandate: None in UDO or Apex Code of Ordinances. Thoroughfare-Facing Fences: Must provide visual interest (Sec. 8.2.7.C.2).

Erecting a fence with the unfinished side facing a neighbor or right-of-way (outside the Downtown Festival District alley exception) violates UDO Sec. 8.2.7.A.2. Building over a property line is a civil trespass that the Town does not enforce, but a court can order removal. A residential thoroughfare-facing fence that lacks the required visual interest required by Sec. 8.2.7.C.2 can be cited by the Planning Department.

The rules around neighbor fence rules in Apex lean permissive, but that does not mean anything goes.

Permit Requirements

Apex regulates fence design, height, materials, and location under Section 8.2.7 of the Unified Development Ordinance, reviewed by the Planning Department. Building permits are administered by the Apex Building Inspections Division at (919) 249-3418, 322 N Mason St, which enforces the North Carolina State Building Code. Wake County handles separate building and electrical permits for pools, hot tubs, and spas holding more than 24 inches of water. Fences must comply with Sec. 8.2.7 height, material, finish, and right-of-way standards.

Key details: UDO Authority: Sec. 8.2.7 Fences, Walls, and Berms. Zoning Review: Apex Planning Department. Building Inspections: (919) 249-3418 - 322 N Mason St, Apex NC 27502. State Building Code: NC State Building Code (enforced under NCGS Ch. 160D). Finished-Side Rule: Fences must be finished on side facing right-of-way or adjacent property (Sec. 8.2.7.A.2).

Installing a fence that does not meet UDO Sec. 8.2.7 material, height, finished-side, or right-of-way requirements may result in a stop-work order or a notice of violation from the Apex Planning Department or Building Inspections. Privately installed fences within required landscape buffers without integration into the approved buffer plan violate Sec. 8.2.7.E.1 and may have to be removed. Fences erected in Riparian Buffers (other than those installed by the Town) violate Sec. 8.2.7.E.1 and Sec. 6.1.11.

Pool Barriers

Pool barriers in Apex are governed by Appendix V (2018 edition) / Appendix NC-A (2024 edition) of the North Carolina Residential Code, applied through Wake County Inspections and the Apex Building Inspections Division. The barrier must be at least 48 inches above grade on the side facing away from the pool, openings must not allow passage of a 4-inch sphere, the maximum vertical clearance between grade and the bottom of the barrier is 2 inches (4 inches with concrete or fixed solid material), and pedestrian access gates must open outward, be self-closing, and have a self-latching device. Under NC Session Law 2023-108 (HB 488), Apex cannot impose stricter local amendments to the NC Residential Code barrier provisions.

Key details: Minimum Barrier Height: 48 inches above grade (NCRC App. V, AV105.2 Item 1). Max Sphere Opening: No 4-inch sphere may pass through (AV105.2 Item 2). Max Vertical Clearance: 2 inches grade-to-bottom (4 inches over concrete/solid). Pedestrian Gate: Self-closing, self-latching, opens outward (AV105.2 Item 8). Above-Ground Pool: Barrier may be mounted on pool structure with 4-inch clearance max.

A residential pool barrier shorter than 48 inches above grade violates AV105.2 Item 1. Openings allowing passage of a 4-inch sphere (such as standard wide-spaced ornamental fencing) violate Item 2. A gate that does not open outward, is not self-closing, or lacks a self-latching device violates Item 8. Failed barrier inspections will result in denial of the final pool inspection and the pool may not be placed in service.

This is not one of those rules that cities tend to ignore. Apex actively enforces its pool barriers requirements.

Approved Materials

Apex UDO Sec. 8.2.7.A.1 permits fences and walls constructed of 'wood, stone, brick, decorative concrete block, wrought iron, (or products created to resemble these materials), or a combination of any of these materials.' Chain link is permitted only under the restrictions in Sec. 8.2.7.A.4. All fencing must be finished on the side facing a public right-of-way or adjacent properties (Sec. 8.2.7.A.2), except within the Downtown Festival District where the alley-facing side may be unfinished.

Key details: Permitted Materials: Wood, stone, brick, decorative concrete block, wrought iron (Sec. 8.2.7.A.1). Lookalike Products: Allowed if they resemble listed materials. Combinations: Mixing listed materials permitted. Chain Link: Allowed subject to Sec. 8.2.7.A.4 restrictions. Finished Side: Must face right-of-way or neighbor (Sec. 8.2.7.A.2).

Building a fence from materials not listed in Sec. 8.2.7.A.1 (and not falling within the lookalike-product exception) violates the ordinance. Failure to install fencing with the finished side toward the right-of-way or neighbor (outside the Downtown Festival District alley exception) violates Sec. 8.2.7.A.2. Chain link fencing that fails the vinyl-coating or location standards in Sec. 8.2.7.A.4 is non-compliant.

Retaining Walls

Apex regulates retaining structures under UDO Sec. 8.1.6 (Retaining Structures) and treats freestanding walls under Sec. 8.2.7 (Fences, Walls, and Berms). Retaining-wall construction is also subject to the North Carolina State Building Code (NC Residential Code R404 for foundation/retaining walls; NC Building Code Chapter 18 for non-residential), enforced by the Apex Building Inspections Division at (919) 249-3418. The UDO's 7-foot freestanding-wall cap (Sec. 8.2.7.B.1) does not apply to grade-retaining walls, but retaining walls 4 feet or taller (measured bottom of footing to top of wall) typically require engineered design and a building permit under the NC State Building Code.

Key details: Freestanding Wall Cap: 7 feet, including piers/posts/finials (Sec. 8.2.7.B.1). Front Yard Wall Cap: 48 inches (Sec. 8.2.7.B.2). Engineered Retaining Wall Threshold: Over 48 inches unbalanced backfill - NC Residential Code R404. State Code Authority: NC State Building Code (NCGS Ch. 143, Art. 9). State Preemption: Session Law 2023-108 (HB 488) reorganized NC Code Councils.

Constructing a freestanding decorative wall over 7 feet (or over 48 inches in a front yard) violates UDO Sec. 8.2.7.B. Building a grade-retaining wall over 4 feet (bottom of footing to top of wall) without an engineered design and building permit violates the NC State Building Code as enforced by Apex Building Inspections. Walls placed in public rights-of-way or in recorded utility/drainage easements must be removed at the owner's expense.

Fence Requirements

Apex UDO Section 8.2.7 establishes the core fence requirements: 7-foot freestanding limit (4 feet in front yards), the finished side must face the right-of-way or neighbor, fences may not be installed around detention/retention basins (Sec. 6.1.13.B.10), and Sec. 8.2.7.F (Maintenance) requires owners to keep fences plumb, in good repair, with no more than 20% of surface disfigured, cracked, ripped, or peeling. Non-residential fences abutting a public right-of-way must be set back at least 4 feet with a minimum of 3 small evergreen shrubs every 20 feet (Sec. 8.2.7.C.1).

Key details: Authority: Apex UDO Sec. 8.2.7 Fences, Walls, and Berms. Detention/Retention Basin Fencing: Prohibited (Sec. 6.1.13.B.10, Sec. 8.2.7 intro). Non-Residential ROW Setback: At least 4 feet from right-of-way (Sec. 8.2.7.C.1). ROW Plantings: Minimum 3 small evergreen shrubs every 20 feet. Surface Disrepair Threshold: Maximum 20% disfigured/cracked/peeling (Sec. 8.2.7.F.1).

A fence around a detention or retention basin violates Sec. 6.1.13.B.10. A non-residential fence less than 4 feet from a public right-of-way, or one missing the required evergreen shrub plantings every 20 feet, violates Sec. 8.2.7.C.1. A fence with more than 20% disfigured, cracked, ripped, or peeling surface, or that leans (not plumb), violates Sec. 8.2.7.F and can be ordered repaired by Apex Code Enforcement.

Material Restrictions

Apex UDO Sec. 8.2.7.A controls fence materials. Plywood, particleboard, sheet metal, concrete slabs, and concrete barriers may not be used for fencing. Barbed wire is generally prohibited and may only be used 'in conjunction with a permitted agricultural use or in conjunction with the permitted keeping of horses or livestock,' though up to 2 feet of barbed wire is allowed on top of another fence type for safety in industrial and utility uses. Chain link in residential districts is restricted to side and rear yards of individual lots, and chain link in non-residential districts must be coated black, brown, or dark green vinyl (except industrial/utility chain link, which does not require coating).

Key details: Approved Materials: Wood, stone, brick, decorative concrete block, wrought iron (Sec. 8.2.7.A.1). Prohibited Materials: Plywood, particleboard, sheet metal, concrete slabs/barriers (Sec. 8.2.7.A.3). Barbed Wire: Only with agricultural/livestock use; 2-ft cap on industrial/utility (Sec. 8.2.7.A.5). Chain Link in Non-Residential: Must be black/brown/dark green vinyl coated (Sec. 8.2.7.A.4.a). Chain Link in Residential: Side and rear yards only, individual lots only (Sec. 8.2.7.A.4.b).

A plywood, particleboard, sheet metal, concrete-slab, or concrete-barrier fence violates Sec. 8.2.7.A.3 and can be ordered removed by the Planning Department or Code Enforcement. Barbed wire on a non-agricultural residential lot violates Sec. 8.2.7.A.5. Uncoated chain link in a non-residential or non-industrial district violates Sec. 8.2.7.A.4.a. Chain link in a residential front yard violates Sec. 8.2.7.A.4.b.

Compared to other cities, Apex takes a harder line on material restrictions. The enforcement and penalty structure reflects that.

The Bottom Line

Apex is tougher than many cities when it comes to fence regulations. Out of the 8 rules covered here, 2 are rated strict. If you are a homeowner, renter, or business owner in Apex, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.

Keep in mind that Apex can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
