Delaware County PA Map
A Delaware County PA map is the suburban Philadelphia county, not the state of Delaware. The parcel viewer is the county's own GIS map.

A Delaware County PA map is Delaware County, Pennsylvania, on the southwest side of Philadelphia. It is not the state of Delaware, and it is not Delaware County, Ohio. The county seat is Media. The parcel and lot-line map people usually want is the county's real-estate GIS viewer.
Open the Delaware County parcel map
- If you are browsing from the national directory, start at the Platbookmapper home page and search Delaware County.
- Or open Delaware County in the Pennsylvania directory.
- Use the official GIS link. The county map listed there is the Delaware County parcel viewer.
- Search the site address or the parcel number (folio) on the tax bill.
What you get, and what you do not
You get the county's tax parcel: the outline used for assessment, the parcel identifier, and a way to see the lot against the street. You do not get a survey. Row houses, side yards, and older borough lots are easy to misread on a screen. A fence or a driveway on the aerial photo is not the legal line.
If the search landed you in the state of Delaware or in Delaware County, Ohio, go back to Platbookmapper and pick the county that actually taxes the property. The site links out to local parcel and lot-line GIS maps. It does not host them.
Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey.
