Lot Dimensions, Zoning, and Land Use Details
The physical characteristics and regulatory status of a property are clearly documented in the parcel data.

This is the spatial data that forms the basis of the Allegheny County land parcel maps. Zoning information is another crucial element.

The financial data within the real estate parcel data Allegheny County is perhaps the most frequently accessed.

| Total Tax Due | The sum of county, municipal, and school taxes. | The amount the owner must pay annually. |
| Exemption Status | Whether the property has a tax exemption (e.g., Homestead). | Reduces the assessed value used for taxation. |
The current tax year’s assessed values are based on the latest county-wide reassessment. The last major reassessment was in 2012, but new construction and improvements trigger annual updates to individual parcel values. Tax bills are issued annually, typically in the spring.
