Pittsburgh's Fence Regulations: The Rules That Matter
Every city handles fence regulations a little differently. In Pittsburgh, Pennsylvania, there are 4 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
Pittsburgh caps fences at 6 feet in rear and interior side yards, but limits front-yard and street-facing side-yard fences to 4 feet and requires an open, ornamental design in that zone.
Key details: Rear/interior side yard: 6 ft max, may be opaque. Front/street-facing side yard: 4 ft max, open/ornamental only. Barbed wire, razor edge: Banned citywide. Taller fence option: Administrator's Exception, max +1 ft. Governing law: Zoning Code § 912.04.K.
A fence over the height cap violates the Zoning Code; the city can require it be lowered or removed. Building taller than 4 or 6 feet needs an Administrator's Exception under § 922.08, capped at one extra foot, and only if it won't harm neighboring properties or streets.
Fence Permit Requirements
Backyard fences up to six feet tall need no permit in Pittsburgh; anything taller requires a building permit from the Bureau of Building Inspection under the city's amended residential code.
Key details: Permit-exempt height: 6 feet or shorter. Governing provision: Pittsburgh Code § 1002.02 (IRC R105.2). Permit issuer: Bureau of Building Inspection (BBI). Also applies: Zoning height/setback rules, Title 9 Ch. 918.
Building a fence taller than six feet without a permit is a Uniform Construction Code violation; BBI can require a stop-work order, fines, and compliance work under Title 10's enforcement provisions.
Retaining Walls
Pittsburgh exempts retaining walls up to four feet tall, measured from the bottom of the footing to the top of the wall, from a building permit. Taller walls, or any wall holding back a surcharge, need a permit and engineered plans.
Key details: Permit-exempt height: 4 ft, footing to top of wall. Surcharge exception: surcharge-bearing walls always need a permit. Enforcing agency: Bureau of Building Inspection. Governing code: Residential Code, R105.2 as locally amended.
Building a permit-required retaining wall without one is a Building Title violation, punishable under section 903 of Act 45 (35 P.S. § 7210.903); the Bureau of Building Inspection can also issue a stop-work order until a permit is obtained.
Material Restrictions
Pittsburgh requires fences and walls to use compatible, durable materials like iron grating, wood, stone, or brick, bans barbed and razor wire citywide, and limits chain-link with slat inserts to General Industrial districts.
Key details: Allowed materials: Iron grating, wood, stone, or brick. Wire ban: Barbed and razor wire prohibited citywide. Chain-link w/ slats: Only allowed in GI district. Long walls: Over 40 ft require visual relief.
Violating fence-material rules is a zoning code violation: the Bureau of Building Inspection can order corrections, and Pittsburgh Code § 924.04.G authorizes fines up to $1,000 per offense, with each day a separate violation.
The Bottom Line
Pittsburgh'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 Pittsburgh is broadly strict or permissive.
Keep in mind that Pittsburgh 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.
