Maryland property data
2,065,406 residential parcels in Maryland on our national assessor and recorder file, with owner, mailing address, structure characteristics, values, sales and liens keyed to the parcel. Fill rates below are measured on the 09/01/2026 snapshot, residential parcels as the denominator.
Field fill rates in Maryland
The share of residential parcels in Maryland on which each field is populated. Owner name, mailing address, lot size, assessed value and coordinates are filled on effectively every parcel nationally and are omitted. The structure fields are the ones that vary, because they come from county field cards that not every county publishes.

Denominator: parcels with a residential land use code. Fill rates on all parcels, including vacant land and commercial, are lower; on parcels with a building they are higher and the denominator varies by state. We use residential throughout so states compare.
What the Maryland file is used for
- Loading the state into a warehouse or product under a bulk license
- Owner and mailing-address appends for Maryland addresses
- Insurance underwriting inputs where the structure fields are filled
- Purchase, refinance and new-homeowner triggers from the recorder side of the file
Maryland sits near the national pattern: the basic characteristics are well covered and the structure codes are filled on a majority but not all parcels.
