=== Identify Vacant Land ===
The land use fields (“USECODE” and “USEDESC”) include publicly-owned property as a land use. For this reason, the land use field has limited applicability to the types of land uses common among publicly-owned properties, including government facilities, parks, un-buildable property such as hillsides, and land that once held structures but is now vacant.[[File:Gtech 2014 vacant land survey.jpg|thumb|Results of 2014 GTECH Vacant Land Survey with Building Assessed Value|396x396px]]

Three municipalities in Allegheny County tax land and buildings at different rates. For this reason, the assessment file contains a “FAIRMARKETLAND,” “FAIRMARKETBUILDING,” and “FAIRMARKETTOTAL” (total = land + building) value. To identify vacant land, the split land/structure valuation has been used with good reliability. Ground-truthing efforts on properties whose “FAIRMARKETBUILDING” = 0 have shown that they typically do not have a structure. In 2014, a comprehensive survey of vacant parcels in the North Side of Pittsburgh was conducted by [https://gtechstrategies.org/ GTECH Strategies] (GTECH). GTECH’s data collection efforts targeted properties whose building assessment (FAIRMARKETBUILDING) =0. They hired and trained neighborhood residents to collect the data. Of the 6,882 parcels with an assessed building value of “0,” 4,791 (70%) did not contain a structure. Many of the remaining 2,699 parcels were also vacant, but apparently were not included in the survey as they were located in a railroad or utility right of way, were a park, cemetery, or condominium common property. The locations of these parcels can be seen in Figure 1.
