Harrisburg caps residential fence height at 4 feet in front yards and 6 feet in side and rear yards under Zoning Code Ch. 7-301. Corner lots are subject to a sight-triangle limitation. Fences over 6 feet require a zoning permit. Historic districts (Old Uptown, Shipoke, Capitol) require Architectural Review Board approval.
Residential fence height in Harrisburg is governed by the Zoning Code, Chapter 7-301 (Fences and Walls). In all residential zoning districts (R-1, R-2, R-3, and Mixed Use Residential), fences may not exceed 4 feet in any required front yard area and 6 feet in side or rear yards, measured from finished grade to the highest point of the fence. Fences exceeding 6 feet, or any fence in a non-residential district above 8 feet, require a zoning permit and review by the Bureau of Codes Administration within the Department of Building and Housing Development.
Corner lots are bound by a sight-triangle rule: within the triangular area formed by the curb lines at an intersection, fences and hedges may not exceed 3 feet to preserve visibility for motorists, cyclists, and pedestrians — a common point of citation in Allison Hill's grid streets. Barbed wire, razor ribbon, and electrified fencing are prohibited in residential districts and require a special-use approval in commercial or industrial zones.
Because Harrisburg contains several locally-designated historic districts (Old Uptown, Shipoke, Capitol Heights, and the National Register-listed Capitol Park), any fence in these districts requires review by the Architectural Review Board (ARB) regardless of height, and chain link is generally not approved. Pool barriers must be at least 4 feet high with self-closing, self-latching gates per the Pennsylvania Uniform Construction Code adopted by reference. Property line disputes are civil — Pennsylvania has no cost-sharing fence statute, so each owner is responsible for their own fence.
Fences exceeding height limits without a variance: Notice of Violation with $300–$1,000 fines per occurrence, plus removal or modification at owner expense. Building without a required zoning permit: separate $500+ fine. Sight-triangle violations typically must be corrected within 30 days. Historic district violations carry additional fines from the ARB and may require restoration to approved design.
