Before you buy a lot near West Mifflin with a plan in mind, pull up the Pleasant Hills zoning map before anything else: a district label decides setbacks, lot size and uses. This Pleasant Hills guide covers: which office sets the rules for a lot, matching a lot to its zoning district, and the questions that save a wasted trip.
Which office controls the Pleasant Hills zoning map

To find out which side of the line a parcel is on: ask whether the parcel near Jefferson Hills is inside the boundary.
