Is a Fence Considered a Structure in Pittsburgh?

If you’re planning to install or replace a fence in Pittsburgh, one question comes up more often than almost any other:

“Is my fence considered a structure?”

It’s a fair question—and one that causes real problems when it’s misunderstood.

Homeowners often assume fences are simple improvements that don’t require permits. Commercial property owners may assume fencing is only a zoning issue. In Pittsburgh, both assumptions can lead to delays, redesigns, or stop-work notices.

Compared to more rural areas of Western Pennsylvania, Pittsburgh enforces fence regulations more closely. That’s not because the city wants to make projects difficult—it’s because dense neighborhoods, steep terrain, and public safety concerns demand a higher level of review.

Why Pittsburgh Treats Some Fences as “Structures”

Pittsburgh isn’t a flat, open suburb. It’s a compact city built around:

• Hills and slopes

• Retaining walls

• Sidewalks and public rights-of-way

• Neighboring properties that often sit just feet apart

That reality shapes how the city regulates construction.

From the city’s perspective, fences can affect:

• Public safety (collapse, tipping, detachment in high winds)

• Visibility at intersections and driveways

• Pedestrian and vehicle traffic

• Liability exposure when fences serve a protective function

Because of this, Pittsburgh evaluates fences through two separate lenses:

• Zoning compliance

  • Location

  • Height

  • Setbacks

  • Appearance

• Structural safety

  • Wind loads

  • Foundations

  • Materials

  • Stability

Many homeowners expect fencing to fall entirely under zoning rules. But once a fence performs a safety, load-bearing, or mechanical function—or exceeds certain thresholds—PLI may review it as a structure.

That surprises people, but it’s intentional.

How Pittsburgh and Pennsylvania Define a “Structure”

To understand how fences are classified, you have to start with how codes define a structure.

Under the International Building Code (IBC)—adopted in Pennsylvania through the Uniform Construction Code (UCC)—a structure is broadly defined as:

Anything that is constructed or erected with a fixed location on the ground.

Pennsylvania enforces this through the UCC, administered by the Department of Labor & Industry:

Pittsburgh then applies those standards locally through its zoning and building review process, overseen by the Department of Permits, Licenses & Inspections (PLI):

The Key Point Most People Miss

It’s not about what you call it—it’s about what it does.

If a fence:

• Resists wind loads

• Supports gates

• Protects people from a fall

• Integrates mechanical or electrical systems

…it may be treated as a structure even if it “looks like a fence.”

The definition is intentionally broad so the city can evaluate safety case by case.

Fences That Typically Do Not Count as a Structure

Many everyday fencing projects do not require a building permit beyond zoning approval.

Common Residential Examples

• Standard residential fences (4–6 feet tall)

• Chain link fencing with open mesh

• Ornamental aluminum fencing with spaced pickets

• Wood or vinyl fences with open airflow

• Simple posts set in shallow concrete footings

• No vehicle gates, motors, or electrical components

This often includes backyard privacy fences or side-yard enclosures.

Common Commercial Examples

• Parking lot perimeter fencing

• Dumpster enclosures

• Equipment screening not serving a safety barrier function

Important:
Not being classified as a “structure” does not mean “no rules.”

Zoning rules still apply under the Pittsburgh Zoning Code (Title Nine):

Fences That Are Commonly Classified as Structures

Where things change is when fencing goes beyond a simple enclosure. Below are the most common triggers seen in real-world PLI reviews.

Fence Height and Wind Load

Height is one of the biggest red flags.

As fences get taller, they behave less like screens and more like walls—especially when solid.

PLI considers:

• Fences over 6 feet

• Long, uninterrupted runs

• Installation on slopes or elevated ground

• Proximity to sidewalks or neighboring properties

• Solid materials (wood panels, vinyl privacy fencing)

Solid fences catch wind very differently than open designs—especially in Pittsburgh’s terrain and weather conditions.

Load-Bearing or Safety Function

When a fence’s purpose shifts from boundary marking to physical protection, it often becomes structural.

Examples include:

• Guardrails along drop-offs

• Fencing at the top of retaining walls

• Barriers protecting pedestrians from hazards

• Pool fencing with fall-prevention requirements

Here, PLI focuses on what happens if the fence fails, not just how it looks.

Vehicle Gates and Heavy Gate Systems

Vehicle access changes everything.

Common structural gate systems include:

• Cantilever gates

• Sliding or rolling gates

• Wide swing gates for commercial access

• Heavy steel or composite gates

Gate weight, movement, and stopping force directly affect:

• Post sizing

• Footing depth

• Structural stability

These systems almost always receive closer scrutiny and may require engineered drawings.

Electrified, Motorized, or Integrated Systems

Once electrical or mechanical components are involved, the project enters a different regulatory category.

This includes:

• Motorized access-control gates

• Electrified security fencing

• Integrated cameras or lighting

• Keypads and card readers

PLI must review these for electrical safety, mechanical operation, and liability risk.

Foundations and Structural Supports

The deeper and more complex the foundation, the more likely the fence is classified as structural.

Common triggers:

• Deep piers

• Continuous concrete footings

• Structural steel posts

• Reinforced concrete elements

At that point, the fence behaves like a permanent structure, not a removable enclosure.

The Wind Load Test: A Major Determining Factor

Wind load is often the deciding factor in whether engineering is required.

PLI evaluates:

• Fence height and length

• Solid vs. open design

• Material type

• Terrain and exposure

Pittsburgh’s hills, valleys, and wind corridors create localized wind pressures. Solid fencing acts like a sail, transferring force directly into posts and footings.

When wind load becomes a concern, PLI may require:

• Engineering calculations

• Stamped drawings

• Revised footing designs

This isn’t red tape—it’s about preventing fence failures that damage property or injure pedestrians.

Zoning Permit vs. Building Permit: What’s the Difference?

One of the most common points of confusion is assuming fencing only falls under zoning.

In Pittsburgh, zoning permits and building permits serve very different purposes.

Zoning Permit

Focuses on placement and compliance, including:

• Height limits

• Setbacks from property lines

• Visibility at corners or driveways

• Neighborhood-specific zoning rules

This is where front-yard fencing, corner lots, and maximum heights are reviewed.

Building Permit

Focuses on construction and safety, including:

• Structural stability

• Wind load resistance

• Footing and post design

• Mechanical or electrical components

If a fence includes deep foundations, heavy gates, motors, or safety functions, a building permit is often required.

Key Takeaway

• Zoning permits govern placement and appearance

• Building permits govern strength, stability, and safety

• Some fencing projects require both

Many problems arise when zoning approval is assumed to be the final step.

How Pittsburgh PLI Decides If Your Fence Is a Structure

PLI doesn’t rely on a single checkbox. Reviews are detail-driven.

Inspectors typically evaluate:

• Height and overall length

• Materials and solidity

• Gate type and size

• Foundation depth

• Proximity to public rights-of-way

• Intended function (security, safety, access control)

Common review questions include:

• Is this fence resisting wind loads?

• Does it protect people from a fall or hazard?

• Does it include mechanical or electrical components?

• Would failure create a safety risk?

Providing complete details upfront—drawings, specs, photos—can significantly speed up approval.
