Label definitions, source/standardization value meanings, and live coverage access are on that parent page. ⭐ marks the recommended field for its job; fields marked API Queryable can filter the `/parcels/query` endpoint (max 4 fields per query). ### `owner` — Owner Name ⭐ | Schemas | Type | Source | Standardized | API Queryable | | ------------------ | ---- | ---------------------- | ------------ | ------------- | | Premium & Standard | text | Authoritative (County) | Some | **Yes** | **Description: **Local source's record of parcel owner's name. **Use it for:** This is Regrid's primary ownership field, and therefore the best to use in analysis. **Related fields:** `ownfrst`, `ownlast`, `owner2`, `unmodified_owner`, `lbcs_ownership` ⭐, `mailadd` **Coverage:** May not be tracked on public land or rights-of-ways See `owner_pct` in the live [Coverage Report CSV](https://docs.google.com/spreadsheets/d/1rvRYv6_ppZlwbmyi2kbzemot6FOEm2EEPdHPyENTQPE/export?format=csv\&gid=1284673582). **Matched product:** Enhanced Ownership (separate matched dataset available from Regrid) *Also known as: property owner, owner name, who owns this, taxpayer name, deed owner (field aliases: owner\_name, primary\_owner)* ### `lbcs_ownership` — Land Use Code: Ownership ⭐ | Schemas | Type | Source | Standardized | API Queryable | | ---------------- | ------- | ------ | ------------ | ------------- | | **Premium only** | numeric | Regrid | Yes | **Yes** | **Description: **Ownership structure: public, private. See **Use it for:** A standardized 4-digit LBCS code for the parcel's ownership category (private, or public at city, township, county, state, federal, or tribal level), derived by Regrid from the owner name. Standardized nationwide, so it is the field to use for identifying publicly owned land consistently across jurisdictions. Pair with lbcs\_ownership\_desc for the label. > **Do not use it for:** Detailed private-owner classification - all private parcels receive a single private-ownership code. For the owner's name use owner; for the county's own owner-type value use owntype. **Related fields:** `lbcs_ownership_desc`, `owntype`, `owner` ⭐ **How it's made:** Human and automatic classification **Units:** Code · **Valid range:** See linked docs · **Example:** 1000,2000,3000 (100% standardized values, see url) **Coverage:** See `lbcs_ownership_pct` in the live [Coverage Report CSV](https://docs.google.com/spreadsheets/d/1rvRYv6_ppZlwbmyi2kbzemot6FOEm2EEPdHPyENTQPE/export?format=csv\&gid=1284673582). **Related docs:** Standardized Land Use Code Keys *Also known as: ownership type, is it government owned, public land, publicly owned, city county state federal land, private or public, government property (field aliases: LBCS\_ownership\_code, ownership\_code)* ### `lbcs_ownership_desc` — Land Use Code Description: Ownership | Schemas | Type | Source | Standardized | API Queryable | | ---------------- | ---- | ------ | ------------ | ------------- | | **Premium only** | text | Regrid | Yes | — | **Description: **Description of the LBCS numeric code **Use it for:** The human-readable description of the standardized LBCS ownership code (e.g. "Federal", "Private"), the text counterpart to lbcs\_ownership.
