Webmap of Allegheny municipalities and parcel data. Zoom for a clickable parcel map with owner name, property photograph, and link to the County Real Estate website for property sales information.

Map Index Sheets from Block and Lot Grid of Property Assessment and based on aerial photography, showing 1983 datum with solid line and NAD 27 with 5 second grid tics and italicized grid coordinate markers and outlines of map sheet boundaries. Each grid square is 3500 x 4500 feet. Each Index Sheet contains 16 lot/block sheets, labeled from left to right, top to bottom (4 across, 4 down): A, B, C, D, E, F, G, H, J, K, L, M, N, P, R, S. The first (4) numeric characters in a parcelID indicate the Index sheet in which the parcel can be found, the alpha character identifies the block in which most (or all) of the property lies.

This is a connection to the Allegheny County's Geographic Information Systems Group's Open Data Portal. They are pleased to share some of our most comprehensive data sets with the public. You can solve important local issues by exploring and downloading relevant open data, analyzing and combining the datasets using maps, and discovering and building apps.

These datasets are available in a number of formats. You can choose to download them, use REST APIs, or view them directly in an interactive web map. API's provide access as REST, HTML, JSON, GeoJSON, etc.

This dataset overlays a grid on the County to assist in locating a parcel. The grid squares are 3,500 by 4,500 square feet. The data was derived from original MAPINDX: Map Index Sheets from Block and Lot Grid of Property Assessment and based on aerial photography. Tiles are numbered in a clockwise spiral fashion starting with #1 at the point in downtown Pittsburgh. Each tile contains 16 Blocks. Each Index Sheet contains 16 lot/block sheets, labeled from left to right, top to bottom (4 across, 4 down): A, B, C, D, E, F, G, H, J, K, L, M, N, P, R, S. The first (4) numeric characters in a parcelID indicate the Index sheet in which the parcel can be found, the alpha character identifies the block in which most (or all) of the property lies.

Tax liens are a method the government uses to secure an interest in unpaid tax debt. This dataset represents information about county, municipal, school district, and water/sewer tax liens by parcel (and property identification number, where available). This dataset includes the name of the municipality, county or school district filing, the date that the lien was filed, and the tax amount at the date of filing.

This data is based on records that were filed dating back to 1995. This dataset will be updated with the previous month's filings as new data becomes available (typically, close to the beginning of the month).

Delinquent Tax Docket numbers are not unique identifiers. Instead, users need to combine the Delinquent Tax Docket number, the tax year, and the lien description.

This dataset represents our best effort to describe the state of tax liens. Users are encouraged to consult the Allegheny County Department of Court Records web site, as it is the definitive and most reliable source for this information:

https://dcr.alleghenycounty.us/

More detailed and up-to-date information on each lien can be found on that site.

This dataset portrays cell tower locations as points in Allegheny County. The dataset is based on outbuilding codes in the Property Assessment Parcel Database used to identify cell towers for tax year 2016.

Abstract: Boundaries of municipalities within Pennsylvania as delineated for the PennDOT Type 10 general highway maps. Additional information comes from the Pennsylvania Bureau of Municipal Services. This layer contains all classifications of municipality including first and second class townships, boroughs, cities and the town. The shape file reflects a name change from Osborne borough to Glen Osborne borough in Allegheny county and a name change from Abington Township to Waverly Township in Lackawanna county. The shape file also reflects various municipal boundary line tweaks that have occurred since the 2011_01 update. Purpose: Public information and support for transportation planning, design and development. Supplemental_Information: This data is intended for use at 1:24,000 or smaller scale. This layer supercedes and replaces previous versions of padot-borough, padot-city-town, and padot-township.
