Verified from official government sources
Lehigh County does not regulate fence heights directly - under the Pennsylvania Municipalities Planning Code (Act 247 of 1968, 53 P.S. §10101 et seq.), fence rules are set by each municipality's zoning ordinance. The City of Allentown (the county seat) generally caps residential fences at 4 feet in front yards and 6 feet in side and rear yards, with corner-lot vision-clearance requirements. Pennsylvania has no statewide fence-height preemption, so the 25 municipalities in Lehigh County each set their own standards. Most fences in Allentown require a zoning permit before installation.
