What does an assessor's parcel record actually contain?

An assessor's parcel record contains the county's official description of a property for tax purposes: parcel number, legal description, site address, property classification, land and improvement values, assessed value, tax amounts, and physical characteristics such as square footage, lot size, bedrooms, bathrooms, year built, and structure type. The assessor also records the current owner of record and their mailing address.

The exact fields vary by county because each of the 3,000+ U.S. counties, or county equivalents, maintains its own format and data standards. Larger, more digitally accessible counties tend to have richer records with more granular detail (subdivision, zoning, building permits), while rural counties may omit fields like bedroom and bathroom counts entirely. Assessor data also links to tax records, showing delinquencies, exemptions, and assessment history. This makes assessor records one of the more reliable foundational sources for property data.

Assessor records are a starting point, not the finished dataset. PropertyRadar adds value by cleaning and standardizing assessor data across counties, then layering modeled and cross-referenced insights where raw records are incomplete, inconsistent, or recorded differently by jurisdiction.
