Common questions
How many parcels are in Baltimore County, Maryland?
JB PARCEL carries 301,638 parcel records for Baltimore County, Maryland, with owner information on 82 percent of them.
Can I find out who owns a property in Baltimore County?
Yes. Search by owner name, address, or parcel number to pull the record: owner of record and mailing address, assessed values, recorded sales, year built and lot lines on the map. Sale records here currently run through 2026-04-22.
How do I find vacant land or absentee owners in Baltimore County?
We do not hold vacancy data for Baltimore County yet, so this filter has nothing to match there. Vacancy filters work in the counties where we hold the field.
Can I search Baltimore County by lot size or acreage?
Yes. Acreage is on 99 percent of Baltimore County parcels, mapped from the parcel boundary, and the advanced search filters on it directly - set a minimum and maximum to pull every tract in that range, then stack vacancy or absentee ownership on top.
