Property & Parcel Data

Property and parcel data forms the foundational layer of the real estate data stack. It describes the physical and legal characteristics of a land parcel or building: lot boundaries, building footprint, square footage, number of units, year built, construction type, and legal description. This data is sourced primarily from county assessors and GIS departments, then standardized by private aggregators. It is the starting point for virtually every downstream use case — from valuation and investment to insurance and urban planning.
