Object classes

1,072,319 public source records across 97 classes, as of November 01, 2026 at 11:27 PM PST. The class links open current counts and individual records. Counts describe stored source records; multiple sources can describe the same real-world thing. A Google Places result returned for a Marin search does not, by itself, establish a location in the county.

Property and permit coverage

The collected property inventory has 5,348 address-and-city records. Its parcel snapshot contains 96,235 unique assessor parcel IDs and 113,129 address points. Parcel records, address points, buildings, houses, and housing units are different classes and are not interchangeable.

The permit snapshot contains 169,418 source rows representing 168,676 issuer-and-permit-number keys from six jurisdictions. These are collected permit records, not a countywide estimate of construction.

Connected public sources

Browse 5,932 Google reviews, 4,246 Google Places records, 2,796 source-call records, 3,100 public business email records, and 302 professions and healthcare taxonomies. Reviews link to their business, reviewer profile, and source records.
