City limits and county records
Middletown sits in Dauphin County, Pennsylvania, which means parcel data comes from the county. With a lot near Penbrook, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Lots just outside the town limits out by Highspire often follows county rules, not municipal ones.
