Williamsport Zoning & Land Use Guide
Key Zoning Facts
Williamsport Zoning Overview
Williamsport is the county seat of Lycoming County, Pennsylvania, located along the West Branch of the Susquehanna River in north-central Pennsylvania. With a population of approximately 28,356, Williamsport is the principal city of the Williamsport metropolitan area and serves as the economic hub of the region. The city is internationally known as the birthplace of Little League Baseball, hosting the annual Little League World Series in adjacent South Williamsport. Historically, Williamsport was the center of the American lumber industry in the late 19th century, when it was reportedly home to more millionaires per capita than any other city in the world.
The city's zoning is managed by the Planning and Codes Department. Williamsport's land use features a traditional downtown along the river, Victorian-era neighborhoods with notable architecture from the lumber boom era (particularly along Millionaires' Row), commercial corridors, and industrial areas. The city is home to Pennsylvania College of Technology (affiliated with Penn State) and the Williamsport campus of Lycoming College.
