Ownership

Part of the Regrid Parcel Schemas reference. 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 ⭐

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.
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 ⭐

Description: Ownership structure: public, private. See https://www.planning.org/lbcs/standards/ownership/

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)

lbcs_ownership_desc — Land Use Code Description: Ownership

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. Standardized nationwide.

owntype — Owner Type

Description: The county's own classification of owner type, where provided.

Use it for: Coverage and meaning vary by county, and many counties do not populate it at all.

Do not use it for: A consistent public-vs-private or government-level classification across places - county owner-type coding is inconsistent and often absent. For a standardized ownership category that works nationwide, use lbcs_ownership (Premium).
