U.S. City Open Data Census
Powered by Open Data Census
Data about assessed property values including location, assessed value, taxes owed, and owner. Many US cities raise a substantial percentage of annual revenue via property tax assessment. Transparent public access to property assessment data helps keep city tax assessors accountable, allowing property owners to see how their property has been assessed relative to other parcels and providing explanatory context for property taxes owed and/or helping to justify appeals to assessments perceived to be unfair. Property assessment data also helps the public keep property owners accountable. (More info)
