ChescoViews: Search Chester County property records

Chester County, Pennsylvania, residents can look up a property by address, owner name or parcel number through ChescoViews, the county’s interactive mapping service. The map can help locate a parcel before researching a home or asking questions about nearby development.

The records need context. The county archives’ house research guide, page 3 warns that construction dates in assessment information can be inaccurate, particularly for older homes. Connecting a map result with the underlying deed and other historical evidence helps avoid treating one database field as a settled fact.

Find the parcel and keep its identifier

Start at the county’s ChescoViews page and follow its application link. The map’s search panel provides tabs for Address, Owner, UPI, PIN, Street and Intersection. Its address form separates street number, direction, street name, street type and municipality.

Choose the search method that matches the information you have. Keep the parcel identifier with your notes so a later question about a record refers to the same property.

UPI means Uniform Parcel Identifier. PIN means Parcel Identification Number. The county’s UPI explanation says the UPI is a standardized version of the PIN, with specific formatting for recorded documents. Use the appropriate search field for the number you have.

Read the map layers with their limits

The county describes ChescoViews as a tool for viewing land record information. Its mapping FAQ lists parcels, roads, municipal boundaries, floodplains, streams, wetlands, contours and aerial photography among the available information.

The FAQ also explains a common source of confusion: some layers appear only at particular zoom levels. If a selected layer is missing from the map, try zooming closer before drawing a conclusion about what the county has mapped.

The county’s service page says maps can be printed in letter size or 11 by 17 inches. When keeping a map for research, note which layers were visible and when you accessed it.

At the application’s opening disclaimer, the county makes no accuracy warranty and tells users to obtain independent verification of its data. A parcel outline or environmental layer should therefore prompt further checking before a decision that depends on its accuracy.

Check an older home’s construction date

The archives’ Researching Your Chester County Home guide, page 3 explains why a year in assessment data deserves scrutiny. Many construction dates were supplied by owners when information was collected in the 1960s and 1970s. The guide says those dates are often incorrect unless a home is of recent construction.

The same section explains that assessment information can supply a current deed book and page reference. That reference helps a researcher find the recorded deed and begin tracing earlier ownership. Preserve the reference, then compare documents and other evidence before assigning a construction date.

The county continues to link this research guide from its Bureau of Land Records page. It is existing guidance, not an announcement of a new mapping feature.

Take the next question to the right place

For help using ChescoViews, the county lists GIS support at 610 344 6096. Recorder of Deeds staff can explain how to use their resources, but the Bureau of Land Records says they cannot conduct property or title research for the public.

For a proposed development, follow the map search with the relevant application, ordinance and written municipal decision. Our Chester County data center planning records guide explains the distinction between county review and municipal action.

For West Chester tree locations, the borough provides a separate inventory. Our refreshed public tree map report explains tree names, recorded status and asset IDs. Keep that tree identifier separate from a county parcel identifier when asking about a record.

For documents that are not already posted, our Chester County public records request guide explains forms, format choices and response timing. It distinguishes the county process from requests for municipal zoning and building records.

For notifications about recorded documents, the county offers a separate Fraud Notify service. Our Chester County property alerts guide explains enrollment and the records behind an alert.
