Lancaster County sets no wall rule. Your municipality does. Manheim Township requires freestanding walls to be set back 5 feet from side and rear lot lines and caps them at 6 feet in residential yards. All walls must meet the PA Uniform Construction Code. Check your local ordinance.
Retaining and freestanding walls are regulated municipally, not by Lancaster County, under MPC §603. Manheim Township treats freestanding walls like fences for height (42 inches in the front yard, 6 feet in other residential yards) but adds that “freestanding walls shall be setback five (5) feet from side and rear lot lines.” Structural retaining walls must also comply with the Pennsylvania Uniform Construction Code (PA UCC) as enforced by the township, which typically triggers a building permit and engineering for taller walls. Requirements differ across the county's 60 municipalities, so confirm setback, height, and permit thresholds with your local zoning and code office.
Non-compliant walls face a municipal zoning removal/modification order and fines; walls built without required PA UCC review can be red-tagged until an engineered permit is obtained.
