Pennsylvania's Uniform Construction Code sets the statewide permit threshold and engineering standards for retaining walls regardless of municipality.
Under the Pennsylvania Uniform Construction Code (Act 45 of 1999, 35 P.S. 7210.101 et seq.) and 34 Pa. Code Chapter 403, retaining walls over 4 feet in height measured from the bottom of the footing to the top of the wall, or any wall supporting a surcharge, require a building permit and engineered design under the International Building and Residential Codes. This threshold applies in all Pennsylvania municipalities that enforce the UCC. Walls under 4 feet without surcharge are exempt from permit, though local zoning and stormwater rules may still apply.
Pennsylvania UCC violations carry fines up to $1,000 per offense under 35 P.S. 7210.903, plus stop-work orders and required removal or reconstruction. Failed walls causing damage may trigger civil liability and insurance claims.
